Description

Technical Field

[0001] The invention relates to the technical field of motor seats, and in particular to an adjustable motor seat. Background Art

[0002] In the field of mechanical transmission, belt transmission is widely used in a large number of mechanical equipment due to its simple structure, smooth operation, low noise, ability to mitigate impact, low installation and maintenance requirements, and low cost. Figure 1 As shown, Figure 1 It is a schematic diagram of the matching structure of the motor pulley and the reducer pulley in the prior art; a large number of oil pumps use belt transmission between the motor and the reducer. However, based on the principle of friction transmission, it is usually necessary to ensure that the motor pulley 100 and the reducer pulley 200 are aligned during the belt installation process, and to reasonably adjust the tension of the belt 300 to ensure that the belt can work normally and obtain a reasonable life. Usually, the tension required to be generated during the operation of a single belt may reach more than 2000N, which is difficult for manpower to bear, and it is generally not allowed to pry the belt into the pulley groove during the installation process. Therefore, it is necessary to use appropriate methods to replace and install the belt, ensure the alignment of the pulleys and adjust the tension of the belt.

[0003] In general, see Figure 2 As shown, Figure 2 It is a top view of the prior art when the motor pulley and the reducer pulley are not aligned; if the motor pulley 100 and the reducer pulley 200 are not aligned, it will cause the side wear of the belt 300, affecting the life of the belt.

[0004] Figure 3 It is a side view of the belt between the motor pulley and the reducer pulley in the prior art that is not sufficiently tensioned; if the belt 300 between the motor pulley 100 and the reducer pulley 200 is not sufficiently tensioned, the belt 300 and the pulley will slip, friction will generate heat, the belt life will be short and it will not be able to transmit effectively. Only after the correct tension is adjusted, the belt can achieve the best performance and life.

[0005] The motor adjustment method in the prior art relies on a single top screw at the pulley end, which can only achieve single-side longitudinal adjustment and a small adjustable range. If the pulley is misaligned after tensioning, it is necessary to loosen the belt and motor guide rail fixing bolts to adjust the motor position to achieve alignment. Usually, the above process needs to be repeated many times to achieve the final alignment and tensioning state, and lifting equipment is required, which is inconvenient to operate. Figure 4 As shown, Figure 4 It is a schematic diagram of the state that when adjusting the motor position in the prior art, the motor 110 is skewed and the pulley is difficult to align. When the belt force is large, the motor is prone to be skewed and the pulley is difficult to align.

[0043] To make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

In the description of the present invention, unless otherwise specified, "plurality" means two or more.

[0045] See also Figure 1 As shown, Figure 1It is a schematic diagram of the matching structure of the motor pulley and the reducer pulley in the prior art; a large number of oil pumps use belt transmission between the motor and the reducer. However, based on the principle of friction transmission, it is usually necessary to ensure that the motor pulley 100 and the reducer pulley 200 are aligned during the belt installation process, and to reasonably adjust the tension of the belt 300 to ensure that the belt can work normally and obtain a reasonable life. Usually, the tension required to be generated during the operation of a single belt may reach more than 2000N, which is difficult for manpower to bear, and it is generally not allowed to pry the belt into the pulley groove during the installation process. Therefore, it is necessary to use appropriate methods to replace and install the belt, ensure the alignment of the pulleys and adjust the tension of the belt.

[0046] In general, see Figure 2 As shown, Figure 2 It is a top view of the prior art when the motor pulley and the reducer pulley are not aligned; if the motor pulley 100 and the reducer pulley 200 are not aligned, it will cause the side wear of the belt 300, affecting the life of the belt.

[0047] Figure 3 It is a side view of the belt between the motor pulley and the reducer pulley in the prior art that is not sufficiently tensioned; if the belt 300 between the motor pulley 100 and the reducer pulley 200 is not sufficiently tensioned, the belt 300 and the pulley will slip, friction will generate heat, the belt life will be short and it will not be able to transmit effectively. Only after the correct tension is adjusted, the belt can achieve the best performance and life.

[0048] The motor adjustment method in the prior art relies on a single top screw at the pulley end, which can only achieve single-side longitudinal adjustment and a small adjustable range. If the pulley is misaligned after tensioning, it is necessary to loosen the belt and motor guide rail fixing bolts to adjust the motor position to achieve alignment. Usually, the above process needs to be repeated many times to achieve the final alignment and tensioning state, and lifting equipment is required, which is inconvenient to operate. Figure 4 As shown, Figure 4 It is a schematic diagram of the state that when adjusting the motor position in the prior art, the motor 110 is skewed and the pulley is difficult to align. When the belt force is large, the motor is prone to be skewed and the pulley is difficult to align.

[0049] In response to the above problems, an embodiment of the present invention provides an adjustable motor seat, which does not require repeated adjustment of the motor installation position, facilitates the alignment of the motor pulley 100 and the reducer pulley 200, and facilitates the belt tensioning between the motor pulley and the reducer pulley.

[0050] Combine the following Figure 5-Figure 12 The technical solution provided by the present invention is described in more detail.

[0051] The adjustable motor seat provided in this embodiment includes a fixed frame 1, a lifting frame 2, a transverse adjustment mechanism and a longitudinal adjustment mechanism, wherein: the lifting frame 2 is rotatably connected to the fixed frame 1 and can be lifted and lowered; the longitudinal adjustment mechanism is located on the lifting frame 2, the longitudinal adjustment mechanism includes a longitudinal movable frame 41, the transverse adjustment mechanism includes a transverse movable frame 51, and the motor is installed on the transverse movable frame 51; the longitudinal movable frame 41 can drive the transverse movable frame 51 to move along the length direction of the lifting frame 2 to put the belt in a tensioned state; the transverse movable frame 51 can slide on the longitudinal movable frame 41 along the width direction of the lifting frame 2 to align the motor pulley 100 and the reducer pulley 200.

[0052] The width direction of the lifting frame 2 and the length direction of the lifting frame 2 are two directions perpendicular to each other, one of which is the X-axis direction, and the other is the Y-axis direction.

[0053] Among them, the fixed frame 1 is used to be fixed to the equipment to be fixed, the motor 110 is fixed on the transverse moving frame 51, and when the longitudinal moving frame 41 moves along the length direction of the lifting frame 2, it can drive the transverse moving frame 51 and the motor 110 to move synchronously, thereby adjusting the distance between the motor 110 and the reducer pulley 200, thereby adjusting the tension of the belt to prevent the belt between the motor pulley 100 and the reducer pulley 200 from being insufficiently tensioned, resulting in sliding of the belt and the pulley, frictional heat generation, short belt life and ineffective transmission.

[0054] The transverse moving frame 51 can slide on the longitudinal moving frame 41 along the width direction of the lifting frame 2, so that the motor pulley 100 is aligned with the reducer pulley 200, preventing the motor pulley 100 and the reducer pulley 200 from being misaligned, which will cause the side wear of the belt and affect the belt life.

[0055] The adjustable motor seat provided in this embodiment can adjust the height of the motor 110 through the lifting frame 2 to achieve rapid tensioning and replacement of the belt 300. The longitudinal movable frame 41 drives the transverse movable frame 51 and the motor 110 to move along the length direction of the lifting frame 2, so that the belt 300 can be tensioned. The transverse movable frame 51 moves along the width direction of the lifting frame 2 on the longitudinal movable frame 41 to adjust the transverse position of the motor 110 to ensure that the motor pulley 100 and the reducer pulley 200 are aligned.

[0056] The adjustable motor seat realizes three-way adjustment of the position of the motor 110, and can realize rapid adjustment of the lateral and longitudinal positions of the motor without repeatedly adjusting the motor installation position, thereby facilitating the alignment of the motor pulley 100 and the reducer pulley 200, and facilitating the belt tensioning between the motor pulley 100 and the reducer pulley 200.

[0057] As an alternative embodiment, see Figure 5-Figure 7As shown, the adjustable motor base also includes a lifting drive device 3, wherein: the first end of the lifting frame 2 is rotatably connected to the fixed frame 1, the lower end of the lifting drive device 3 is rotatably connected to the fixed frame 1, the upper end of the lifting drive device 3 is a telescopic end, and the telescopic end is rotatably connected to the second end of the lifting frame 2. In this embodiment, the second end of the lifting frame 2 is arranged away from the reducer pulley 200, and the lifting drive device 3 can drive the second end of the lifting frame 2 to move up and down.

[0058] The lifting drive device 3 in this embodiment can adjust the angle between the lifting frame 2 and the horizontal plane, such as Figure 6 and Figure 7 See Figure 5 As shown, the end of the lifting frame 2 facing the reducer pulley 200 is rotatably connected to the fixed frame 1 through the rotating shaft 21. When the lifting drive device 3 can drive the end of the lifting frame 2 away from the reducer pulley 200 to rise and fall, the lifting frame 2 as a whole rotates around the rotating shaft 21 as the axis.

[0059] The lifting drive device 3 may be a telescopic cylinder, a telescopic electric cylinder, a hydraulic telescopic rod, etc. Figure 7 As shown, when the telescopic end of the lifting drive device 3 is extended, it can drive the end of the lifting frame 2 away from the reducer pulley 200 to rise, and the motor is fixed on the horizontal moving frame 51. The motor rises, and the distance between the motor pulley 100 and the reducer pulley 200 becomes smaller, so the belt can be easily replaced.

[0060] After the belt is installed on the pulley, the angle adjustment of the lifting frame 2 is lowered to make the belt in a tensioned state. If it is not tensioned or too tight, the longitudinal adjustment mechanism can also be used to adjust the longitudinal position of the motor to make the belt reach a suitable tension state.

[0061] As an alternative embodiment, see Figure 8 and Fig. 9 As shown, the longitudinal adjustment mechanism also includes a longitudinal adjustment rod 42, a first fixed seat 43 and a first movable seat 44, wherein: in this embodiment, the first fixed seat 43 is fixed to the end of the lifting frame 2 away from the reducer pulley 200, the first fixed seat 43 is provided with a first threaded hole, and the first movable seat 44 is fixed to the longitudinal movable frame 41; the longitudinal adjustment rod 42 passes through the first threaded hole, and the end of the longitudinal adjustment rod 42 is rotatably connected with the first movable seat 44, and the rotation of the longitudinal adjustment rod 42 can push the longitudinal movable frame 41 to move along the length direction of the lifting frame 2. The lifting frame 2 is provided with a longitudinal guide rail 22, which is provided along the length direction of the lifting frame 2, and the longitudinal movable frame 41 is slidably connected with the longitudinal guide rail 22; the first movable seat 44 is fixedly provided with a first bearing seat 45, and the longitudinal adjustment rod 42 is rotatably connected with the first bearing seat 45 to ensure that the longitudinal adjustment rod 42 can rotate flexibly.

[0062] Among them, the longitudinal adjustment rod 42 is provided with an external thread. Since the longitudinal adjustment rod 42 is threadedly connected to the first threaded hole, and the end of the longitudinal adjustment rod 42 is rotatably connected to the first bearing seat 45, when the longitudinal adjustment rod 42 is turned, the longitudinal adjustment rod 42 pushes the longitudinal movable frame 41 to slide along the longitudinal guide rail 22, and the longitudinal movable frame 41 moves along the length direction of the lifting frame 2. When the longitudinal adjustment rod 42 stops being turned, the position of the longitudinal movable frame 41 no longer changes, that is, the position of the longitudinal movable frame 41 is determined.

[0063] As an alternative embodiment, see Fig.10 and Fig.11 , Fig.12 As shown, the transverse adjustment mechanism also includes a transverse adjustment rod 52, a second fixed seat 53 and a second movable seat 54, wherein: the second fixed seat 53 is fixed to the side of the longitudinal movable frame 41, a second threaded hole is provided on the second fixed seat 53, and the second movable seat 54 is fixed on the transverse movable frame 51; the transverse adjustment rod 52 passes through the second threaded hole, and the end of the transverse adjustment rod 52 is rotatably connected with the second movable seat 54, and the rotation of the transverse adjustment rod 52 can push the transverse movable frame 51 to move along the width direction of the lifting frame 2. The longitudinal movable frame 41 is provided with a transverse guide rail, which is provided along the width direction of the lifting frame 2, and the transverse movable frame 51 is slidably connected with the transverse guide rail; a second bearing seat 55 is fixedly provided on the second movable seat 54, and the transverse adjustment rod 52 is rotatably connected with the second bearing seat 55 to ensure that the transverse adjustment rod 52 can rotate flexibly.

[0064] Among them, an external thread is provided on the lateral adjustment rod 52. Since the lateral adjustment rod 52 is threadedly connected to the second threaded hole, and the end of the lateral adjustment rod 52 is rotatably connected to the second bearing seat 55, when the lateral adjustment rod 52 is turned, the lateral adjustment rod 52 pushes the lateral moving frame 51 to slide along the lateral guide rail, and the lateral moving frame 51 moves along the width direction of the lifting frame 2. When the lateral adjustment rod 52 stops being turned, the position of the lateral moving frame 51 no longer changes, that is, the position of the lateral moving frame 51 is determined.

[0065] See also Fig.12 As shown, the second fixed seat 53 is provided with a lubrication hole 9 for lubricating the movable parts. Similarly, the first fixed seat 43 can also be provided with a lubrication hole 9. The lubrication hole 9 mainly lubricates the external thread of the corresponding adjustment rod. The first bearing seat 45 and the second bearing seat 55 are greased and sealed during assembly.

[0066] See also Fig.12 As shown, the locking nut 56 threadedly connected on the lateral adjustment rod 52 is used to lock the lateral adjustment rod 52 after adjusting to the appropriate position, limit its rotation, and improve the stability of the structure. Of course, the longitudinal adjustment rod can also be provided with a corresponding locking nut to lock the longitudinal adjustment rod.

[0067] As an alternative embodiment, see Fig.10 and Fig.11 As shown, at least two mounting parts (mounting rails 6) for fixing the motor are provided on the transverse moving frame 51, and the mounting parts (mounting rails 6) are arranged at intervals along the length direction of the lifting frame 2, and the distance between the two mounting parts (mounting rails 6) is adjustable.

[0068] The distance between the two mounting parts can be adjusted to flexibly adapt to motors of different sizes, with a wide range of applications.

[0069] As an alternative embodiment, see Fig.10 and Fig.11 As shown, the mounting portion includes a mounting rail 6 , which extends along the width direction of the lifting frame 2 .

[0070] The motor can slide to a predetermined position along the mounting rail 6 and then be locked in this position to complete the adjustment of the initial position of the motor. The above structure can also achieve lateral adjustment of the motor position, that is, adjust the position of the motor in the width direction of the lifting frame 2.

[0071] In this embodiment, when the motor is installed, the installation guide rail 6 can be used as the primary adjustment of the lateral position of the motor, and rotating the lateral adjustment rod 52 can be used as the secondary adjustment of the lateral position of the motor.

[0072] As an alternative embodiment, see Fig.10 and Fig.11 As shown, the mounting portion is fixed on the adjusting block 7, and an adjusting hole 71 is provided on the adjusting block 7. The adjusting hole 71 is a long strip hole and extends along the length direction of the lifting frame 2. The locking member 8 passes through the adjusting hole 71 to lock the adjusting block 7 on the transverse moving frame 51, and when the locking member 8 is fixed at different positions of the adjusting hole 71, the distance between the two mounting portions can be adjusted.

[0073] The locking member 8 may be a locking bolt and nut assembly. When the locking member 8 is loosened, the locking member 8 and the adjustment hole 71 can slide relative to each other to adjust the distance between the two mounting rails. After the distance between the two mounting rails is adjusted, the mounting rails can be locked on the transverse moving frame 51 by tightening the locking member 8.

[0074] As an alternative embodiment, see Figure 6 As shown, the fixing frame 1 includes a horizontal seat 11 and a support rod 12, one end of the horizontal seat 11 is fixed on the device to be fixed, the support rod 12 is arranged obliquely, the bottom end of the support rod 12 is fixed on the device to be fixed, and the high end of the support rod 12 is fixedly connected to the fixing frame 1.

[0075] The horizontal seat 11, the support rod 12 and the equipment to be fixed can form a stable triangular structure, thereby improving the stability of the structure and ensuring stable operation of the motor.

[0076] Generally, during use, the lifting drive device 3 can be operated to make the lifting frame 2 in a horizontal state, and then the motor 110 is installed on the mounting guide rail 6, and the lateral position of the motor 110 is adjusted to ensure that the motor pulley 100 and the reducer pulley 200 are aligned. The longitudinal adjustment rod 42 is pre-adjusted according to the belt length to make the motor in a suitable position; then, the lifting drive device 3 is used to make the end of the lifting frame 2 facing the reducer pulley 200 in a raised state, at which time the distance between the motor pulley 100 and the reducer pulley 200 becomes smaller, and the belt can be easily loaded. After the belt 300 is installed on the pulley, the end of the lifting frame 2 facing the reducer pulley 200 is lowered to make the belt 300 in a tensioned state. If it is not tensioned or too tight, the longitudinal adjustment rod 42 can also be used to adjust the longitudinal position of the motor to make the belt 300 reach a suitable tension state.

[0077] When replacing the belt, generally, it is only necessary to control the lifting drive device 3 to raise the motor. At this time, the distance between the motor pulley 100 and the reducer pulley 200 becomes smaller, and the belt can be replaced.

[0078] Compared with the traditional single top screw adjustment method, this mechanism has the following advantages:

[0079] 1. It is three-way adjustable, which can realize the rapid adjustment of the motor's lateral position without repeatedly adjusting the motor's installation position.

[0080] 2. The motor installation operation avoids repeated adjustments.

[0081] 3. The belt can be quickly tightened and replaced by adjusting the lifting frame 2.

[0082] 4. It can be applied to situations where the belt tension is large (the advantages are more obvious under conditions of large motors and multiple belts).
