Description

Technical Field

[0001] This application relates to the field of transmission device technology, and more specifically, to a timing belt tensioning device and tensioning method. Background Technology

[0002] Dual synchronous belt drives have been widely used in various precision machinery, and their transmission accuracy is closely related to the tension.

[0003] Current tensioning methods largely rely on skilled workers adjusting the tension manually based on their experience. During manual adjustment, one synchronous belt is typically tensioned first, followed by the adjustment of the other. Adjusting the tension of the second belt can disturb the tension of the already adjusted belt, making it difficult to achieve equal tension between the two belts. This can lead to asynchronous transmission, tooth skipping, or even belt breakage. Furthermore, relying on skilled workers' experience for manual adjustment combined with instrument testing results in a cumbersome and time-consuming process. Summary of the Invention

[0046] Optionally, after placing the first motor and the second motor into the two grooves of the base of the tensioning device of the synchronous belt, and before using the adjusting component to push the motor mounting base horizontally relative to the first motor and the second motor in the first direction to simultaneously adjust the tension of the first synchronous belt and the second synchronous belt, the method further includes:

[0049] Optionally, after using the adjusting component to push the motor mounting base horizontally relative to the first motor and the second motor in the first direction to simultaneously adjust the tension of the first synchronous belt and the second synchronous belt, the method further includes:

[0050] Adjusting the adjusting member of the first fixed adjusting assembly, pushing the motor mounting base horizontally relative to the first motor along the axial direction of the adjusting member, so as to finely adjust the tension of the first synchronous belt;

[0051] Adjusting the adjusting member of the second fixed adjusting assembly, the motor mounting base is pushed horizontally relative to the second motor along the axial direction of the adjusting member, so as to finely adjust the tension of the second synchronous belt.

[0052] The beneficial technical effects of the technical solutions provided in this application include:

[0053] In this embodiment of the application, the dual synchronous belt drive device includes a first motor and a second motor, both of which are mounted on a motor mounting base in a manner that allows for relative horizontal displacement, a driven shaft mounted on the motor mounting base in a manner that does not allow for relative horizontal displacement, a first synchronous belt sleeved on the first motor and the driven shaft, and a second synchronous belt sleeved on the second motor and the driven shaft.

[0054] The timing belt tensioning device includes a base and an adjusting component mounted on the base. A first motor and a second motor are respectively embedded in two grooves in the base. When the adjusting component pushes the motor mounting base horizontally relative to the first and second motors along a first direction (i.e., the direction of the perpendicular bisector of the horizontal line segment connecting the centers of the two grooves), it is equivalent to pushing the driven shaft horizontally relative to the first and second motors. This causes the distance between the driven shaft and the first motor, and the distance between the driven shaft and the second motor, to change simultaneously (e.g., increase simultaneously), thus simultaneously adjusting (e.g., simultaneously tensioning) the tension of the first and second timing belts, achieving simultaneous tension. The tension is preset; moreover, the first direction of the adjustment component is orthogonal to the horizontal line segment connecting the centers of the two grooves and intersects at the midpoint of the horizontal line segment. This can avoid mutual interference when the tension of the first and second synchronous belts is adjusted sequentially, or can minimize the interference. Even if there is still a small amount of interference, it will be canceled out in real time by the synchronous adjustment, so that the tension force is evenly distributed after adjustment. This can effectively avoid the problem of tension force deviation and transmission asynchrony caused by adjusting the tension of the two synchronous belts sequentially, thereby significantly improving the transmission stability and synchronization accuracy of the dual synchronous belt transmission device and extending the service life of the synchronous belt.

[0055] Moreover, the tensioning device of the synchronous belt is easy to operate. It does not require skilled workers to repeatedly try and adjust based on experience. The tensioning of the first and second synchronous belts can be completed simultaneously by pushing the adjustment component once, thereby improving the adjustment efficiency.

[0091] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0092] Dual synchronous belt drives are widely used in various precision machinery, and their transmission accuracy is closely related to their tension. Current tensioning methods mostly rely on skilled workers adjusting manually based on experience. During manual adjustment, one synchronous belt is usually tensioned first, and then the other is adjusted. Adjusting the tension of the second synchronous belt can disturb the tension of the already adjusted belt, making it difficult to achieve equal tension between the two belts. This can lead to asynchronous transmission, tooth skipping, or even belt breakage. Furthermore, relying on skilled workers' experience for manual adjustment combined with instrument testing makes the adjustment process cumbersome and time-consuming.

[0093] The technical solution of this application and how it solves the above-mentioned technical problems are described in detail below with specific embodiments. It should be noted that the following embodiments can be referenced, borrowed, or combined with each other, and the same terms, similar features, and similar implementation steps in different embodiments will not be described again.

[0094] This application provides a timing belt tensioning device 1, such as... Figures 1 to 8 As shown, the tensioning device 1 of the synchronous belt includes: a base 11 and an adjustment component 12.

[0095] The base 11 has at least two grooves, which are configured to accommodate and limit the first motor 21 and the second motor 22, respectively. The dual synchronous belt drive device 2 includes a first motor 21 and a second motor 22, both of which are disposed on the motor mounting base 24 in a manner that allows relative horizontal displacement, a driven shaft 23 disposed on the motor mounting base 24 in a manner that does not allow relative horizontal displacement, a first synchronous belt 25 sleeved on the first motor 21 and the driven shaft 23, and a second synchronous belt 26 sleeved on the second motor 22 and the driven shaft 23.

[0096] Adjustment component 12 is mounted on base 11;

[0097] The adjustment component 12 is configured to push the motor mounting base 24 horizontally relative to the first motor 21 and the second motor 22 along a first direction a, so as to simultaneously adjust the tension of the first synchronous belt 25 and the second synchronous belt 26; the first direction a is the direction of the perpendicular bisector of the horizontal line segment connecting the centers of the two grooves.

[0098] In this embodiment, the dual synchronous belt drive device 2 includes a first motor 21 and a second motor 22, both of which are mounted on the motor mounting base 24 in a manner that allows for relative horizontal displacement, a driven shaft 23 mounted on the motor mounting base 24 in a manner that does not allow for relative horizontal displacement, a first synchronous belt 25 sleeved on the first motor 21 and the driven shaft 23, and a second synchronous belt 26 sleeved on the second motor 22 and the driven shaft 23.

[0099] The tensioning device 1 of the synchronous belt includes a base 11 and an adjusting component 12 disposed on the base 11. A first motor 21 and a second motor 22 are respectively embedded in two grooves of the base 11. When the adjusting component 12 pushes the motor mounting base 24 horizontally relative to the first motor 21 and the second motor 22 along a first direction (i.e., the direction of the perpendicular bisector of the horizontal line segment connecting the centers of the two grooves), it is equivalent to pushing the driven shaft 23 horizontally relative to the first motor 21 and the second motor 22, causing the distance between the driven shaft 23 and the first motor 21 and the distance between the driven shaft 23 and the second motor 22 to change simultaneously (e.g., increase simultaneously), thus simultaneously adjusting the tension of the first synchronous belt 25 and the second synchronous belt 26. Adjustment (e.g., simultaneous tensioning) can simultaneously achieve the preset tension; moreover, the first direction of the adjustment component 12 is orthogonal to the horizontal line segment connecting the centers of the two grooves and intersects at the midpoint of the horizontal line segment. This can avoid mutual interference when adjusting the tension of the first synchronous belt 25 and the second synchronous belt 26 separately, or can minimize the interference. Even if there is still a small amount of interference, it will be canceled out in real time by the synchronous adjustment, so that the tension force is evenly distributed after adjustment. This can effectively avoid the problem of tension force deviation and transmission asynchrony caused by adjusting the tension of the two synchronous belts one after the other, thereby significantly improving the transmission stability and synchronization accuracy of the dual synchronous belt transmission device 2 and extending the service life of the synchronous belt.

[0100] Moreover, the tensioning device 1 of the synchronous belt is easy to operate. It does not require skilled workers to repeatedly try and adjust based on experience. The tensioning of the first synchronous belt 25 and the second synchronous belt 26 can be completed simultaneously by pushing the adjustment component 12 once, thereby improving the adjustment efficiency.

[0101] Alternatively, in one possible implementation of this application, such as Figures 1 to 4 , Figure 6 and Figure 7 As shown, the tensioning device 1 of the synchronous belt also includes: a first fixing adjustment component 13, a second fixing adjustment component 14, and a limiting component 15.

[0102] The first fixed adjustment component 13 and the second fixed adjustment component 14 are both fixed on the base 11 and symmetrically arranged on both sides of the adjustment component 12. They are configured such that at least a portion of the structure can move along its respective axis to define the position of the corresponding motor, and at least another portion of the structure can move along its respective axis to drive the motor mounting base 24 to move.

[0103] The limiting component 15 is fixed on the base 11 and is used to limit the horizontal position adjustment margin of the motor mounting seat 24 of the dual synchronous belt drive device 2.

[0104] In this embodiment, the first fixed adjustment component 13 and the second fixed adjustment component 14 have the same structure. The first fixed adjustment component 13 and the second fixed adjustment component 14 are symmetrically arranged on both sides of the adjustment component 12 along the second direction b. The first fixed adjustment component 13 is used to limit the installation position of the first motor 21 and to fine-tune the tension of the first synchronous belt 25. The second fixed adjustment component 14 correspondingly constrains the installation position of the second motor 22 and fine-tunes the tension of the second synchronous belt 26. The limiting component 15, through an adjustable stop structure, precisely constrains the maximum displacement of the motor mounting base 24 in the first direction a, ensuring that the tension of the dual synchronous belt drive device 2 is always within a preset safety threshold during the adjustment process, avoiding synchronous belt overload or engagement failure due to excessive adjustment.

[0105] Alternatively, in one possible implementation of this application, such as Figures 1 to 5 As shown, the base 11 includes: a base plate 111 and a first base 112 and a second base 113 arranged on the base plate 111 along a first direction a.

[0106] The first base 112 has a concave first curved surface 1121 and a second curved surface 1122 on both sides of its end near the second base 113; the second base 113 has a concave third curved surface 1131 and a fourth curved surface 1132 on one side near the first base 112; the first curved surface 1121, the third curved surface 1131 and the base plate 111 enclose to form a first groove 114 with a notch in its side wall; the second curved surface 1122, the fourth curved surface 1132 and the base plate 111 enclose to form a second groove 115 with a notch in its side wall; the first groove 114 and the second groove 115 are arranged along a second direction b parallel to the base plate 111, the first groove 114 is used to limit the first motor 21 and the second groove 115 is used to limit the second motor 22; the first direction a and the second direction b intersect.

[0107] In this embodiment, a first base 112 and a second base 113 are arranged along a first direction a on a base plate 111, with a gap between them. The first curved surface 1121 of the first base 112, the third curved surface 1131 of the second base 113, and the base plate 111 together form a first groove 114, used to accommodate and limit the first motor 21. The second curved surface 1122 of the first base 112, the fourth curved surface 1132 of the second base 113, and the base plate 111 together form a second groove 115, used to accommodate and limit the second motor 22. The sidewalls of the first groove 114 and the second groove 115 are adapted to the outer contours of the first motor 21 and the second motor 22, ensuring stable motor installation and accurate axial positioning. The first groove 114 and the second groove 115 are symmetrically distributed along the first direction a, enabling the first motor 21 and the second motor 22 to maintain mechanical balance during installation and operation, effectively suppressing vibration transmission.

[0108] The base plate 111 has multiple mounting holes to facilitate the initial fixing of the first motor 21 and the second motor 22 to the base plate 111. Then, the first motor 21 is limited by the first fixing adjustment component 13 and the second motor 22 is limited by the second fixing adjustment component 14, so as to ensure that the first motor 21 and the second motor 22 remain fixed when the tensioning device 1 of the synchronous belt adjusts the tension of the first synchronous belt 25 and the second synchronous belt 26.

[0109] Optionally, in this embodiment, the side of the second substrate 113 away from the first substrate 112 is surrounded by the bottom plate 111 to form a fourth groove 116, which is used to place the driven shaft 23.

[0110] Alternatively, in one possible implementation of this application, such as Figures 1 to 4 and Figure 6 As shown, the adjustment assembly 12 includes: a guide rail component 121, a first adjustment rod 122, and a first adjustment element 123.

[0111] The guide rail component 121 is fixed on the first base 112; the base 11 includes a base plate 111 and a first base 112 and a second base 113 arranged on the base plate 111 along the first direction a.

[0112] The first adjusting rod 122 extends along the first direction a, passes through the guide rail component 121, and is movably connected to the guide rail component 121.

[0113] The first adjusting member 123 is located along the first direction a. One end of the first adjusting member 123 is fixedly connected to the first adjusting rod 122, and the shape of the other end is adapted to the shape of the contact point of the motor mounting base 24. The first adjusting member 123 is slidably connected to the guide rail member 121, and the first adjusting rod 122 is configured to drive the first adjusting member 123 to slide horizontally along the guide rail member 121.

[0114] In this embodiment, the first adjusting rod 122 includes a lead screw. The first adjusting rod 122 is threadedly engaged with the guide rail component 121. Rotating the first adjusting rod 122 causes the first adjusting member 123 to slide horizontally along the guide rail component 121. The other end of the first adjusting member 123 contacts the motor mounting base 24 and pushes the motor mounting base 24 to move along the first direction a. At the same time, in conjunction with the frequency meter for real-time detection, the tension of the first synchronous belt 25 and the second synchronous belt 26 simultaneously reaches the preset tension range, avoiding synchronization errors caused by adjusting the tension separately.

[0115] Alternatively, in one possible implementation of this application, such as Figures 1 to 4 and Figure 6 As shown, the first adjusting member 123 has a concave fifth curved surface 1231 and a sixth curved surface 1232 on both sides of one end near the second base 113.

[0116] The motor mounting base 24 has a seventh curved surface 241 and an eighth curved surface 242 protruding on the outer periphery of the first motor 21 and the second motor 22, respectively. It is configured such that when the first adjusting member 123 contacts the motor mounting base 24, the fifth curved surface 1231 fits with the seventh curved surface 241, and the sixth curved surface 1232 fits with the eighth curved surface 242.

[0117] In this embodiment, the connection between the seventh curved surface 241 and the eighth curved surface 242 is a concave arc transition, and the connection between the fifth curved surface 1231 and the sixth curved surface 1232 is a convex arc transition. Together, they form an adaptive envelope contact structure. When the first adjusting member 123 pushes the motor mounting base 24 to move, the fifth curved surface 1231 and the seventh curved surface 241, and the sixth curved surface 1232 and the eighth curved surface 242 are always in surface contact, ensuring smooth force transmission and uniform force distribution. This avoids deformation of the motor mounting base 24 or tension adjustment errors of the first synchronous belt 25 and the second synchronous belt 26 caused by local stress concentration.

[0118] Alternatively, in one possible implementation of this application, such as Figures 1 to 3 and Figure 6 As shown, the guide rail component 121 includes a fixing member 1211 and a guide rail 1212 connected sequentially along the first direction a.

[0119] The fastener 1211 extends in a direction perpendicular to the base 11, and at least a portion of the first adjusting rod 122 passes through the fastener 1211.

[0120] The guide rail 1212 extends along the first direction a, and the first adjusting member 123 is disposed on the guide rail 1212 and slidably connected to the guide rail 1212.

[0121] In this embodiment, the upper surface of the first base 112 is provided with a slot for embedding the bottom flange of the guide rail 1212, ensuring that the guide rail 1212 is installed firmly and axially positioned accurately; the slot opening faces upward, and the two side walls are provided with guide slopes to facilitate the quick alignment and sliding of the guide rail 1212; the extension direction of the fixing member 1211 is perpendicular to the extension direction of the first base 112, and the fixing member 1211 is fixed to the first base 112; the guide rail 1212 extends along the first direction a, and the guide rail 1212 is fixedly connected to the fixing member 1211, so that the guide rail 1212 is fixed to the first base 112.

[0122] The first adjusting rod 122 includes a lead screw, and the first adjusting rod 122 is threadedly engaged with the fixing member 1211;

[0123] The first adjusting member 123 is disposed on the guide rail 1212 and can slide along the axial direction of the guide rail 1212. One end of the first adjusting member 123 is fixedly connected to the first adjusting rod 122. By rotating the first adjusting rod 122, the first adjusting member 123 is driven to translate along the guide rail 1212, thereby pushing the motor mounting base 24 to move in the first direction a, so as to simultaneously adjust the tension of the first synchronous belt 25 and the second synchronous belt 26. The thrust direction of this adjustment process is precise and the adjusting component 12 has a self-locking function, which can prevent the first adjusting rod 122 and the first adjusting member 123 from shifting due to vibration or load changes after adjustment, ensuring long-term stability of tension.

[0124] Alternatively, in one possible implementation of this application, such as Figures 1 to 4 and Figure 7 As shown, the first fixed adjustment component 13 includes: a first limiting component 131 and an adjustment component 132.

[0125] The first limiting member 131 is fixedly connected to the bottom plate 111 at its bottom. The side of the first limiting member 131 near the second base 113 is adapted to the shape of the first motor 21 and is used to limit the first motor 21. The base 11 includes the bottom plate 111 and the first base 112 and the second base 113 arranged on the bottom plate 111 along the first direction a.

[0126] The adjusting member 132 is disposed above the first limiting member 131. In a plane parallel to the base plate 111, the line connecting the center of the first motor 21 and the center of the driven shaft 23 is collinear with the axis of the adjusting member 132. The adjusting member 132 is configured to push the motor mounting base 24 to move horizontally relative to the first motor 21 along the axial direction of the adjusting member 132, so as to adjust the tension of the first synchronous belt 25.

[0127] In this embodiment of the application, the first limiting member 131 of the first fixed adjustment assembly 13 is used to circumferentially limit the first motor 21; when the adjusting member 132 of the first fixed adjustment assembly 13 moves along its axial direction, it pushes the motor mounting base 24 to move horizontally relative to the first motor 21, so as to precisely adjust the tension of the first synchronous belt 25.

[0128] The first fixed adjustment assembly 13 and the second fixed adjustment assembly 14 have the same structure. The first limiting member 131 of the second fixed adjustment assembly 14 is used to circumferentially limit the second motor 22. When the adjusting member 132 of the second fixed adjustment assembly 14 moves axially, it pushes the motor mounting base 24 to move horizontally relative to the second motor 22, so as to precisely adjust the tension of the second synchronous belt 26. The first fixed adjustment assembly 13, the second fixed adjustment assembly 14 and the adjustment assembly 12 work together to first pre-tighten the first synchronous belt 25 and the second synchronous belt 26 simultaneously along the resultant force direction through the adjustment assembly 12. Then, the first fixed adjustment assembly 13 and the second fixed adjustment assembly 14 respectively perform independent fine adjustment of the first synchronous belt 25 and the second synchronous belt 26 to ensure that the tension of the first synchronous belt 25 and the second synchronous belt 26 is balanced and does not interfere with each other. This can compensate for the tension imbalance caused by manufacturing tolerances, assembly errors and long-term wear in the dual synchronous belt drive device 2, and improve the transmission accuracy.

[0129] Alternatively, in one possible implementation of this application, such as Figures 1 to 4 and Figure 7 As shown, the first limiting member 131 includes: a first fixed seat 1311, a second fixed seat 1312, a movable part 1313, and a fastener 1314.

[0130] The first fixing seat 1311 is fixed on the base plate 111.

[0131] The second fixing seat 1312 is fixed on the base plate 111. The first fixing seat 1311 and the second fixing seat 1312 are arranged in sequence along the line connecting the center of the driven shaft 23 and the center of the first motor 21. The second fixing seat 1312 is provided with a third groove on the side away from the first fixing seat 1311.

[0132] Movable part 1313 is movably set in the third groove.

[0133] The fastener 1314 includes a fastening part 13141 and a lever part 13142 connected to each other; the lever part 13142 is located between the fastening part 13141 and the movable member 1313, and is configured such that when the fastening part 13141 is pressed down, the lever part 13142 drives the movable member 1313 to move horizontally.

[0134] In this embodiment, along the line connecting the center of the driven shaft 23 and the center of the first motor 21, the first fixed seat 1311 and the second fixed seat 1312 are arranged sequentially with a gap between them. The first fixed seat 1311 includes a plate-like structure, and the bottom of the latching part 13141 of the latching member 1314 is fixed to the first fixed seat 1311. One end of the rod part 13142 is movably connected to the latching part 13141. The second fixed seat 1312 has a third groove on the side facing the second base 113. The movable member 1313 is movably disposed in the third groove. One end of the movable member 1313 is connected to the rod part 13142, and the shape of the other end is adapted to the outer contour of the first motor 21. When the latching part 13141 is pressed, it pushes the connected rod part 13142 to move horizontally. The rod part 13142 drives the movable part 1313 to move along the line connecting the center of the driven shaft 23 and the center of the first motor 21 until it is in close contact with the outer contour of the first motor 21, thereby limiting the first motor 21. When the latching part 13141 is released, the movable part 1313 returns to its initial position under the action of the rod part 13142. At this time, the first motor 21 regains its degree of freedom, which facilitates quick disassembly and fine adjustment.

[0135] In this embodiment, the movable part 1313 can be made of PU (Polyurethane) adhesive with a Shore temperature of 70-75, which can prevent scratches on the surface of the first motor 21 during the clamping process, thereby protecting the accuracy and appearance integrity of the first motor 21.

[0136] It should be noted that the limiting principle of the first limiting member 131 of the second fixed adjustment assembly 14 on the second motor 22 is completely the same as the limiting principle of the first limiting member 131 of the first fixed adjustment assembly 13 on the first motor 21, except that the object of action is changed from the first motor 21 to the second motor 22, which will not be elaborated here.

[0137] Alternatively, in one possible implementation of this application, such as Figures 1 to 4 and Figure 7 As shown, the adjusting component 132 includes: a third fixed seat 1321, a second adjusting rod 1322, and a second adjusting member 1323.

[0138] The third fixing seat 1321 is fixed on the second fixing seat 1312.

[0139] The second adjusting rod 1322 passes at least partially through the third fixing seat 1321 and is movably connected to the third fixing seat 1321.

[0140] The second adjusting member 1323 is disposed on the side of the second adjusting rod 1322 near the first motor 21. It is configured to adjust the second adjusting rod 1322. The second adjusting rod 1322 drives the second adjusting member 1323 to move horizontally, pushing the motor mounting base 24 to move horizontally relative to the first motor 21, so as to adjust the tension of the first synchronous belt 25.

[0141] In this embodiment, the second adjusting rod 1322 includes a lead screw, which is threadedly engaged with the third fixed seat 1321. By rotating the second adjusting rod 1322, the second adjusting member 1323 can be driven to move precisely along the axial direction, thereby pushing the motor mounting seat 24 to move horizontally relative to the first motor 21, thus fine-tuning the tension of the first synchronous belt 25. Moreover, the adjusting member 132 has a self-locking function to ensure that after the tension adjustment is completed, the adjusting member 132 remains stable for a long time without external force intervention.

[0142] In this embodiment, the second adjusting member 1323 may be made of PU (Polyurethane) adhesive with a Shore temperature of 70-75, which can prevent scratches on the surface of the motor mounting base 24 during the adjustment process, thereby protecting the accuracy and appearance integrity of the motor mounting base 24.

[0143] It should be noted that the adjustment principle of the adjustment member 132 of the second fixed adjustment assembly 14 on the tension of the second synchronous belt 26 is completely the same as the adjustment principle of the adjustment member 132 of the first fixed adjustment assembly 13 on the tension of the first synchronous belt 25, except that the object of action is changed from the first synchronous belt 25 to the second synchronous belt 26, which will not be elaborated here.

[0144] Alternatively, in one possible implementation of this application, such as Figures 1 to 4 and Figure 8 As shown, the limiting component 15 is fixed on the second base 113. The base 11 includes a base plate 111 and a first base 112 and a second base 113 arranged along the first direction a on the base plate 111. The limiting component 15 includes a second limiting member 151, a third limiting member 152 and a limiting member 153.

[0145] The second limiting member 151 and the third limiting member 152 are arranged at intervals along the second direction b, and are mirror-symmetrically arranged on both sides of the driven shaft 23; the first direction a intersects the second direction b.

[0146] The limiting member 153, relative to the side of the second limiting member 151 and the third limiting member 152 near the first base 112, is configured to abut against the underside of the motor mounting base 24 and is at least partially located between the first motor 21 and the second motor 22.

[0147] In this embodiment, the second limiting member 151 and the third limiting member 152 are symmetrically arranged on both sides of the driven shaft 23 along the second direction b. The motor mounting base 24 located on one side of the driven shaft 23 is partially embedded in the limiting groove of the second limiting member 151, and the other side is correspondingly embedded in the limiting groove of the third limiting member 152, ensuring that the motor mounting base 24 slides smoothly along a preset trajectory during horizontal adjustment, preventing tilting or shaking. The limiting member 153 is fixed to the second base 113, and the limiting member 153 is located at one end of the second base 113 near the first base 112. The shape of the end of the limiting member 153 near the first base 112 matches the end face contour of the second base 113. The side of the motor mounting base 24 closest to the first base 112 is at least partially located on the limiting member 153; the limiting member 153, the second limiting member 151 and the third limiting member 152 work together to provide multi-point support and precise positioning for the motor mounting base 24, avoiding adjustment errors caused by the motor mounting base 24 not moving along the preset path during tension adjustment, thereby improving the synchronization accuracy and operational stability of the dual synchronous belt drive device 2.

[0148] In this embodiment, the limiting member 153 is used to support the motor mounting base 24 and prevent the motor mounting base 24 from tilting when placed. The limiting member 153 is provided with multiple mounting holes for securing the limiting member 153 to the second base 113 with fasteners.

[0149] Alternatively, in one possible implementation of this application, such as Figures 1 to 4 and Figure 8 As shown, the second limiting member 151 includes: a first fixing plate 1511, a first adjusting block 1512, and a second adjusting block 1513.

[0150] The first fixing plate 1511 is fixed to the second base 113.

[0151] The first adjusting block 1512 is disposed on the first fixed plate 1511 in a manner that allows it to move relative to the first fixed plate along the second direction b.

[0152] The second adjusting block 1513 is disposed on the first fixed plate 1511 in a manner that allows it to move relative to the first fixed plate along the first direction a.

[0153] In this embodiment, the third limiting member 152 is mirror-symmetrical to the second limiting member 151. The third limiting member 152 includes a second fixing plate 1521, a third adjusting block 1522, and a fourth adjusting block 1523; wherein, the second fixing plate 1521 is fixed to the second base 113, the third adjusting block 1522 is slidably disposed on the second fixing plate 1521 along the second direction b, and the fourth adjusting block 1523 is slidably disposed on the second fixing plate 1521 along the first direction a.

[0154] The third adjusting block 1522 and the first adjusting block 1512 both extend along the first direction a and respectively fit against the guide surfaces on both sides of the motor mounting base 24, forming a bidirectional guide reference surface; the fourth adjusting block 1523 and the second adjusting block 1513 extend along the second direction b and respectively abut against the end face of the motor mounting base 24 near the driven shaft 23, forming an orthogonal limiting constraint, so that the degree of freedom of the motor mounting base 24 in the two-dimensional plane is completely suppressed. The first adjusting block 1512 and the third adjusting block 1522 can slide along the second direction b, while the second adjusting block 1513 and the fourth adjusting block 1523 slide along the first direction a. Thus, according to the size difference of the motor mounting base 24 of the dual synchronous belt drive device 2 produced in different batches, the position of each adjusting block can be flexibly adjusted to achieve adaptive limiting, ensuring limiting accuracy, and thus ensuring that the tensioning device 1 of the synchronous belt can be used to adjust the tension of the synchronous belt for dual synchronous belt drive devices 2 produced in different batches.

[0155] Based on the same inventive concept, this application provides a method for tensioning a synchronous belt, such as... Figure 9 As shown, the tensioning method includes the following steps:

[0156] S101: The first motor 21 and the second motor 22 are respectively placed in the two grooves of the base 11 of the tensioning device 1 of the synchronous belt; the dual synchronous belt drive device 2 includes a first motor 21 and a second motor 22, both of which are arranged on the motor mounting base 24 in a manner that allows relative horizontal displacement, a driven shaft 23 arranged on the motor mounting base 24 in a manner that does not allow relative horizontal displacement, a first synchronous belt 25 sleeved on the first motor 21 and the driven shaft 23, and a second synchronous belt 26 sleeved on the second motor 22 and the driven shaft 23.

[0157] S102: The adjustment component 12 is used to push the motor mounting base 24 to move horizontally relative to the first motor 21 and the second motor 22 along the first direction a, so as to simultaneously adjust the tension of the first synchronous belt 25 and the second synchronous belt 26.

[0158] In this embodiment, the dual synchronous belt drive device 2 includes a first motor 21 and a second motor 22, both of which are mounted on a motor mounting base 24 with relative horizontal displacement, a driven shaft 23 mounted on the motor mounting base 24 without relative horizontal displacement, a first synchronous belt 25 sleeved on the first motor 21 and the driven shaft 23, and a second synchronous belt 26 sleeved on the second motor 22 and the driven shaft 23. The tensioning device 1 of the synchronous belt includes a base 11 and an adjusting component 12 mounted on the base 11. The first motor 21 and the second motor 22 are respectively embedded in two grooves of the base 11. The perpendicular bisector of the horizontal line segment connecting the extension direction of the adjusting component 12 and the center of the two grooves is perpendicular to the vertical line. The two synchronous belts are aligned in the same direction, ensuring that the tension of the first synchronous belt 25 and the second synchronous belt 26 is balanced and does not interfere with each other during the adjustment process. When the adjustment component 12 pushes the motor mounting base 24 to move horizontally relative to the first motor 21 and the second motor 22 along the vertical line, the first synchronous belt 25 and the second synchronous belt 26 can be tensioned synchronously, so that the first synchronous belt 25 and the second synchronous belt 26 can reach the preset tension at the same time. After adjustment, the tension force is evenly distributed, which can effectively avoid the problem of tension force deviation and transmission asynchrony caused by the two synchronous belts not adjusting their tension at the same time. This can significantly improve the transmission stability and synchronization accuracy of the dual synchronous belt transmission device 2 and extend the service life of the synchronous belt.

[0159] In addition, the tensioning device 1 of the synchronous belt is easy to operate. It does not require skilled workers to repeatedly try and adjust based on experience. The tensioning of the first synchronous belt 25 and the second synchronous belt 26 can be completed simultaneously by pushing the adjustment component 12 once, thereby improving the adjustment efficiency.

[0160] Alternatively, in one possible implementation of this application, such as Figures 1-4 and Figure 7 As shown, in step S101 above, after placing the first motor 21 and the second motor 22 into the two grooves of the base 11 of the tensioning device 1 of the synchronous belt, and in step S102 above, before using the adjusting component 12 to push the motor mounting base 24 horizontally relative to the first motor 21 and the second motor 22 along the first direction a to simultaneously adjust the tension of the first synchronous belt 25 and the second synchronous belt 26, the following steps are also included:

[0161] Adjust a portion of the structure of the first fixed adjustment component 13 to move along the axis of the first fixed adjustment component 13 until a portion of the structure comes into contact with the first motor 21.

[0162] Adjust a portion of the structure of the second fixed adjustment assembly 14 to move along the axis of the second fixed adjustment assembly 14 until the portion of the structure comes into contact with the second motor 22.

[0163] In this embodiment, the first limiting member 131 of the first fixing adjustment assembly 13 is adjusted until the end of the first limiting member 131 near the first motor 21 is in close contact with the outer surface of the housing of the first motor 21, thereby achieving axial limiting of the first motor 21. The first limiting member 131 of the second fixing adjustment assembly 14 is adjusted until the end of the first limiting member 131 of the second fixing adjustment assembly 14 near the second motor 22 is in close contact with the outer surface of the housing of the second motor 22, thereby achieving axial limiting of the second motor 22.

[0164] In this embodiment of the application, after the first motor 21 and the second motor 22 are respectively placed into the first groove 114 and the second groove 115, the fixing bolts at the bottom of the first motor 21 and the second motor 22 are tightened to the pre-tightened state, with an adjustment margin, for the axial limiting operation of the first fixing adjustment component 13 and the second fixing adjustment component 14.

[0165] Optionally, in some embodiments, after the first motor 21 and the second motor 22 are respectively placed into the first groove 114 and the second groove 115, the fixing bolts at the bottom of the first motor 21 and the second motor 22 are fully tightened to ensure that the motors do not move within the grooves.

[0166] Alternatively, in one possible implementation of this application, such as Figures 1-4 and Figure 7 As shown, after step S102 above, in which the adjusting component 12 pushes the motor mounting base 24 horizontally relative to the first motor 21 and the second motor 22 along the first direction a to simultaneously adjust the tension of the first synchronous belt 25 and the second synchronous belt 26, the following steps are also included:

[0167] Adjusting the adjusting member of the first fixed adjusting assembly 13, the motor mounting base 24 is pushed horizontally relative to the first motor 21 along the axial direction of the adjusting member, so as to finely adjust the tension of the first synchronous belt 25.

[0168] Adjusting the adjusting member of the second fixed adjusting assembly 14, the motor mounting base 24 is pushed horizontally relative to the second motor 22 along the axial direction of the adjusting member, so as to finely adjust the tension of the second synchronous belt 26.

[0169] In this embodiment, when the adjusting member 132 of the first fixed adjusting assembly 13 moves axially, it pushes the motor mounting base 24 to move horizontally relative to the first motor 21, thereby precisely adjusting the tension of the first synchronous belt 25. When the adjusting member 132 of the second fixed adjusting assembly 14 moves axially, it pushes the motor mounting base 24 to move horizontally relative to the second motor 22, thereby precisely adjusting the tension of the second synchronous belt 26. The first fixed adjusting assembly 13, the second fixed adjusting assembly 14, and the adjusting assembly 12 work together to first pre-tighten the first synchronous belt 25 and the second synchronous belt 26 simultaneously along the resultant force direction through the adjusting assembly 12, and then independently fine-tighten the first synchronous belt 25 and the second synchronous belt 26 through the first fixed adjusting assembly 13 and the second fixed adjusting assembly 14, respectively, to ensure that the tension of the first synchronous belt 25 and the second synchronous belt 26 is balanced and does not interfere with each other. This can compensate for the tension imbalance caused by manufacturing tolerances, assembly errors, and long-term wear in the dual synchronous belt drive device 2, thereby improving the transmission accuracy.

[0170] During the initial pre-tensioning of the first synchronous belt 25 and the second synchronous belt 26 simultaneously along the resultant force direction by the adjustment component 12, the frequency meter detects in real time, ensuring that the tension of the first synchronous belt 25 and the second synchronous belt 26 reaches the pre-tension range. Then, based on the feedback data from the frequency meter, the first fixed adjustment component 13 and the second fixed adjustment component 14 are finely adjusted along the component force direction until the tension of both the first synchronous belt 25 and the second synchronous belt 26 reaches the target tension range, thus ending the tension adjustment. Using the tensioning method provided in this application embodiment can increase the tension adjustment frequency. Tests show that manually adjusting the tension of two synchronous belts by a skilled worker based on experience takes approximately 30 minutes per adjustment, while using the synchronous belt tensioning device 1 of this application, a single adjustment of the tension of two synchronous belts can be completed in approximately 10 minutes, increasing the adjustment efficiency by more than 2 times.

[0171] By applying the embodiments of this application, at least the following beneficial effects can be achieved:

[0172] 1. In this embodiment, the dual synchronous belt drive device 2 includes a first motor 21 and a second motor 22, both of which are mounted on a motor mounting base 24 with relative horizontal displacement, a driven shaft 23 mounted on the motor mounting base 24 without relative horizontal displacement, a first synchronous belt 25 sleeved on the first motor 21 and the driven shaft 23, and a second synchronous belt 26 sleeved on the second motor 22 and the driven shaft 23; the tensioning device 1 of the synchronous belt includes a base 11 and an adjusting component 12 mounted on the base 11, the first motor 21 and the second motor 22 are respectively embedded in two grooves of the base 11, and the perpendicular bisector of the horizontal line segment connecting the extension direction of the adjusting component 12 and the center of the two grooves is... The two synchronous belts are aligned in the same direction, ensuring that the tension of the first synchronous belt 25 and the second synchronous belt 26 is balanced and does not interfere with each other during the adjustment process. When the adjustment component 12 pushes the motor mounting base 24 to move horizontally relative to the first motor 21 and the second motor 22 along the vertical line, the first synchronous belt 25 and the second synchronous belt 26 can be tensioned synchronously, so that the first synchronous belt 25 and the second synchronous belt 26 can reach the preset tension at the same time. After adjustment, the tension force is evenly distributed, which can effectively avoid the problem of tension force deviation and transmission asynchrony caused by the two synchronous belts not adjusting their tension at the same time. This can significantly improve the transmission stability and synchronization accuracy of the dual synchronous belt transmission device 2 and extend the service life of the synchronous belt.

[0173] In addition, the tensioning device 1 of the synchronous belt is easy to operate. It does not require skilled workers to repeatedly try and adjust based on experience. The tensioning of the first synchronous belt 25 and the second synchronous belt 26 can be completed simultaneously by pushing the adjustment component 12 once, thereby improving the adjustment efficiency.
