Abstract
Description
Technical Field
[0001] This utility model relates to the field of mechanical transmission technology, and in particular to a bearing housing and transmission structure. Background Technology
[0002] In existing technologies, when using shaft-type parts for power transmission, these parts are generally mounted on bearing housings for fixation. Furthermore, in practical applications, operators need to adapt the transmission structure composed of shaft-type parts to different situations. For example, due to limitations in equipment machining and installation precision, or gear wear caused by equipment operating under load, significant deviations may occur in the mechanical fit between the transmission structure composed of shaft-type parts (e.g., the fit between transmission gears). In such cases, it is necessary to adjust the relative positions (e.g., height) of the shaft-type parts to compensate for these deviations and ensure the normal operation of the transmission structure.
[0003] Current methods for adjusting the position of shaft components typically involve adding or removing shims under the bearing to raise or lower the shaft component. Different thicknesses of shims are used to compensate for any discrepancies. However, this method cannot accurately adjust the position of the shaft component in one go, requiring repeated adjustments and resulting in low efficiency. Utility Model Content

Through the cooperation of the first sliding seat, the second sliding seat, and the mounting base, the position (height) of the mounting base in the second direction can be adjusted.

[0027] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.
[0028] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0029] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.
[0030] In the description of this embodiment, the terms "upper," "lower," "left," and "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.
[0031] like Figure 1 As shown, this embodiment provides a bearing housing 100 for supporting a first transmission shaft 101. The bearing housing 100 includes a base plate 1, a sliding seat 2, a mounting seat 3, a first adjusting member 4, and a second adjusting member 5.
[0032] The substrate 1 described above may be in the form of a rectangular plate or an elliptical plate, and those skilled in the art can flexibly configure it according to the actual application scenario.
[0033] Combination Figure 1 , Figure 2 As shown, the aforementioned sliding seat 2 is disposed on the substrate 1 and slidably connected to the substrate 1. The sliding connection between the sliding seat 2 and the substrate 1 can be achieved for example: the sliding seat 2 is placed on the upper surface of the substrate 1, with direct contact between the two, and their relative positions are not fixed, thus allowing the sliding seat 2 to slide relative to the substrate 1; or, a slider is provided at the bottom of the sliding seat 2, and a groove adapted to the slider is provided on the upper surface of the substrate 1, with the two achieving a sliding connection through the cooperation of the slider and the groove. The aforementioned sliding seat 2 includes a first sliding seat 21 and a second sliding seat 22. It is easy to understand that the first sliding seat 21 and the second sliding seat 22 should be slidably connected to the substrate 1 respectively. The first sliding seat 21 and the second sliding seat 22 are symmetrically arranged about the axis of the first transmission shaft 101. In other words, in the first direction X1, the first sliding seat 21 and the second sliding seat 22 are directly opposite each other, and the distance between the axis of the first sliding seat 21 and the axis of the first transmission shaft 101 is the same as the distance between the axis of the second sliding seat 22 and the axis of the first transmission shaft 101.
[0034] The aforementioned mounting base 3 is disposed on the first sliding seat 21 and the second sliding seat 22. A mounting hole 311 is provided on the mounting base 3, and the first drive shaft 101 is installed within this mounting hole 311. It is readily understood that the first drive shaft 101 should be installed within the mounting hole 311 via a rotating bearing.
[0035] The first adjusting member 4 is connected to the first sliding seat 21. The first adjusting member 4 can drive the first sliding seat 21 to move along the first direction X1. Specifically, the first adjusting member 4 is threadedly connected to the first sliding seat 21, and by rotating the first adjusting member 4 (forward or reverse rotation) and utilizing the engagement of the threads, the first sliding seat 21 can be driven to move along the first direction X1; or, the first adjusting member 4 is fixedly connected to the first sliding seat 21 (e.g., welded), and by pulling or pushing the first adjusting member 4, the first sliding seat 21 can be driven to move along the first direction X1.
[0036] The second adjusting member 5 is connected to the second sliding seat 22. The second adjusting member 5 can drive the second sliding seat 22 to move along the first direction X1. The setting method of the second adjusting member 5 is the same as that of the first adjusting member 4, and will not be described again here.
[0037] In the first direction X1, the first sliding seat 21 and the second sliding seat 22 can adjust the position of the mounting seat 3 in the second direction X2 by moving them closer to each other or further apart from each other. Here, the second direction X2 is set at an angle to the first direction X1, for example, 90°. Specifically, the principle by which the movement of the first sliding seat 21 and the second sliding seat 22 in the first direction X1 can adjust the position of the mounting seat 3 in the second direction X2 is as follows: rollers are respectively provided on the upper surfaces of the first sliding seat 21 and the second sliding seat 22, and inclined surfaces are provided on the mounting seat 3 corresponding to the positions of the rollers. The rollers roll on the inclined surfaces, pushing the mounting seat 3 to move in the second direction X2; or, two rollers are provided on the lower surface of the mounting seat 3, and inclined surfaces are respectively provided on the first sliding seat 21 and the second sliding seat 22. The inclined surfaces push the rollers to roll, thus pushing the mounting seat 3 to move in the second direction X2. Of course, those skilled in the art can also set other structures to adjust the position of the mounting seat 3 in the second direction X2 when the first sliding seat 21 and the second sliding seat 22 move along the first direction X1. No further limitations are made here.
[0038] Therefore, the bearing housing 100 provided in this embodiment has a first sliding seat 21 and a second sliding seat 22 slidably connected to a base plate 1, and the first sliding seat 21 and the second sliding seat 22 are symmetrically arranged with the axis of the first transmission shaft 101 as the axis of symmetry. At the same time, a mounting seat 3 with a mounting hole 311 is provided on the first sliding seat 21 and the second sliding seat 22, and the first transmission shaft 101 is installed in the mounting hole 311. In addition, a first adjusting member 4 connected to the first sliding seat 21 and capable of driving the first sliding seat 21 to move along the first direction X1 is provided, and a second adjusting member 5 connected to the second sliding seat 22 and capable of driving the second sliding seat 22 to move along the first direction X1 is provided. Furthermore, in the first direction X1, the first sliding seat 21 and the second sliding seat 22 can be moved closer to each other or moved further away from each other to adjust the position of the mounting seat 3 in the second direction X2. The above configuration allows for the adjustment of the position (height) of a shaft component (i.e., the first drive shaft 101) in the second direction X2. The first adjusting member 4 moves the first sliding seat 21 closer to (or further away from) the second sliding seat 22, while the second adjusting member 5 moves the second sliding seat 22 closer to (or further away from) the first sliding seat 21. Through the cooperation of the first sliding seat 21, the second sliding seat 22, and the mounting base 3, the position (height) of the mounting base 3 in the second direction X2 can be adjusted. Since the first drive shaft 101 is mounted in the mounting hole 311 of the mounting base 3, when the position of the mounting base 3 changes in the second direction X2, the position of the first drive shaft 101 in the second direction X2 changes synchronously. This achieves the adjustment of the position of the first drive shaft 101 in the second direction X2. During this adjustment process, only the first adjusting member 4 and the second adjusting member 5 need to be operated to complete the adjustment. The adjustment steps are few, the process is simple, and repeated adjustments are unnecessary, significantly saving adjustment time and improving work efficiency.
[0039] Furthermore, it is easy to understand that, in order to better support the first drive shaft 101, such as... Figure 1 , Figure 2 As shown, multiple sets of bearing seats 100 (e.g., two sets) can be set simultaneously to support the first drive shaft 101 during use. Furthermore, the base plates 1 of the multiple sets of bearing seats 100 can be connected together, or the multiple sets of bearing seats 100 can share a single base plate 1. This can further improve the stability of the first drive shaft 101 when multiple sets of bearing seats 100 support it.
[0040] In some embodiments, combined with Figure 1 , Figure 2 As shown, the first sliding seat 21 has a first sliding ramp 211 on the side near the mounting base 3, and the second sliding seat 22 has a second sliding ramp 221 on the side near the mounting base 3. That is, with... Figure 2 Taking the shown perspective as an example, the first sliding inclined surface 211 is disposed on the upper surface of the first sliding seat 21, and the second sliding inclined surface 221 is disposed on the upper surface of the second sliding seat 22.
[0041] The mounting base 3, near the sliding base 2, is provided with a third sliding inclined surface 3211 and a fourth sliding inclined surface 3212. That is, with... Figure 2 Taking the view shown as an example, the lower surface of the mounting base 3 is provided with a third sliding inclined surface 3211 and a fourth sliding inclined surface 3212.
[0042] The third sliding inclined surface 3211 on the mounting base 3 is directly opposite to the first sliding inclined surface 211 on the first sliding seat 21, and the fourth sliding inclined surface 3212 on the mounting base 3 is directly opposite to the second sliding inclined surface 221 on the second sliding seat 22. Simultaneously, the third sliding inclined surface 3211 is adapted to the first sliding inclined surface 211, and the fourth sliding inclined surface 3212 is adapted to the second sliding inclined surface 221. In other words, the tilt direction and tilt angle of the third sliding inclined surface 3211 are the same as those of the first sliding inclined surface 211; and the tilt direction and tilt angle of the fourth sliding inclined surface 3212 are the same as those of the second sliding inclined surface 221.
[0043] With the above configuration, after the mounting base 3 is placed on the first sliding seat 21 and the second sliding seat 22, the third sliding inclined surface 3211 contacts the first sliding inclined surface 211, and the fourth sliding inclined surface 3212 contacts the second sliding inclined surface 221. Thus, when the first sliding seat 21 and the second sliding seat 22 move along the first direction X1, the first sliding inclined surface 211 pushes against the third sliding inclined surface 3211, and the second sliding inclined surface 221 pushes against the fourth sliding inclined surface 3212. During this pushing process, the horizontal thrust can be decomposed into a normal force and a tangential force. The vertical component (second direction X2) drives the mounting base 3 to move up and down (i.e., move along the second direction X2). This allows the position of the mounting base 3 in the second direction X2 to be adjusted by the movement of the first sliding seat 21 and the second sliding seat 22 along the first direction X1. Meanwhile, the above-mentioned arrangement enables the mounting base 3 to directly and tightly contact the first sliding seat 21 and the second sliding seat 22, improving the stability of the mounting base 3, the first sliding seat 21 and the second sliding seat 22 during movement, while also enhancing the structural strength of the entire bearing housing 100 and improving its durability.
[0044] In some embodiments, combined with Figure 1 , Figure 2As shown, the first sliding inclined surface 211 and the second sliding inclined surface 221 are symmetrically arranged about the axis of the first transmission shaft 101. Similarly, the third sliding inclined surface 3211 and the fourth sliding inclined surface 3212 are also symmetrically arranged about the axis of the first transmission shaft 101. In other words, the first sliding inclined surface 211 and the second sliding inclined surface 221 have the same inclination angle but opposite inclination directions; the third sliding inclined surface 3211 and the fourth sliding inclined surface 3212 have the same inclination angle but opposite inclination directions. This arrangement facilitates the manufacturing and installation of the mounting base 3, the first sliding base 21, and the second sliding base 22, while also improving the stability of the mounting base 3, the first sliding base 21, and the second sliding base 22 during movement.
[0045] In some embodiments, combined with Figure 1 , Figure 2 As shown, the mounting base 3 includes a mounting portion 31 and a sliding portion 32, with a mounting hole 311 formed in the mounting portion 31. The sliding portion 32 includes a sliding sub-part 321 and a first limiting sub-part 322 and a second limiting sub-part 323 disposed on opposite sides of the sliding sub-part 321. That is, with Figure 4 Taking the shown viewpoint as an example, the first limiting sub-part 322 is disposed on the left side of the sliding sub-part 321, and the second limiting sub-part 323 is disposed on the right side of the sliding sub-part 321. The aforementioned third sliding inclined surface 3211 and the aforementioned fourth sliding inclined surface 3212 are disposed on the sliding sub-part 321.
[0046] In the first direction X1, the first limiting sub-part 322 is located on the side of the first sliding seat 21 opposite to the second sliding seat 22, and the second limiting sub-part 323 is disposed on the side of the second sliding seat 22 opposite to the first sliding seat 21. That is, with Figure 4 Taking the shown perspective as an example, the first limiting sub-part 322 is located on the left side of the first sliding seat 21, and the second limiting sub-part 323 is located on the right side of the second sliding seat 22. The first adjusting member 4 passes through the first limiting sub-part 322 along the first direction X1, and the second adjusting member 5 passes through the second limiting sub-part 323 along the first direction X1. Through the above arrangement, the first limiting sub-part 322 and the second limiting sub-part 323 can respectively limit the first sliding seat 21 and the second sliding seat 22 in the first direction X1, preventing the first sliding seat 21 or the second sliding seat 22 from disengaging from the mounting base 3, thereby improving the reliability of the bearing seat 100 during use.
[0047] In some embodiments, combined with Figure 1 , Figure 2As shown, the first limiting sub-part 322 has a first notch 3221, through which the first adjusting member 4 passes. The second limiting sub-part 323 has a second notch 3231, through which the second adjusting member 5 passes.
[0048] The aforementioned first adjusting member 4 includes a first threaded portion 41, a first abutting portion 42, and a first rotating portion 43 arranged along the first direction X1. The first threaded portion 41 is threadedly connected to the first sliding seat 21, and in the first direction X1, the first limiting portion 322 is located between the first abutting portion 42 and the first rotating portion 43.
[0049] The second adjusting member 5 includes a second threaded portion 51, a second abutting portion 52, and a second rotating portion 53 arranged along the first direction X1. The second threaded portion 51 is threadedly connected to the first sliding seat 21, and the second limiting portion 323 is located between the second abutting portion 52 and the second rotating portion 53 in the first direction X1.
[0050] With the above configuration, after the first rotating part 43 is rotated, the first threaded part 41 of the first adjusting member 4 will rotate accordingly. Under the action of the threaded engagement between the first threaded part 41 and the first sliding seat 21, the first adjusting member 4 can push or pull the first sliding seat 21 to move along the first direction X1. During this process, the first abutting part 42 abuts against the first limiting part 322 (when the first adjusting member 4 pushes the first sliding seat 21 to move), or the first rotating part 43 abuts against the first limiting part 322 (when the first adjusting member 4 pulls the first sliding seat 21 to move). This ensures that the first adjusting member 4 will not move itself while pushing or pulling the first sliding seat 21 to move along the first direction X1. The structure is simple and easy to use.
[0051] Similarly, after rotating the second rotating part 53, the second threaded part 51 of the second adjusting member 5 will rotate accordingly. Under the action of the threaded engagement between the second threaded part 51 and the second sliding seat 22, the second adjusting member 5 can push or pull the second sliding seat 22 to move along the first direction X1. During this process, the second abutting part 52 abuts against the second limiting part 323 (when the second adjusting member 5 pushes the second sliding seat 22 to move), or the second rotating part 53 abuts against the second limiting part 323 (when the second adjusting member 5 pulls the second sliding seat 22 to move). This ensures that the second adjusting member 5 will not move itself while pushing or pulling the second sliding seat 22 to move along the first direction X1. The structure is simple and easy to use.
[0052] In some embodiments, combined with Figure 1 , Figure 2As shown, the first sliding seat 21 is provided with a third limiting portion 212. This third limiting portion 212 includes two third limiting sub-parts 2121 extending along a first direction X1, and the two third limiting sub-parts 2121 are spaced apart along a third direction X3 on the first sliding inclined surface 211. In the third direction X3, the distance between the two third limiting sub-parts 2121 is the same as the size of the mounting base 3, that is, the distance between the two third limiting sub-parts 2121 is the same as the width of the mounting base 3. Here, the first direction X1, the second direction X2, and the third direction X3 are arranged at an angle to each other, for example, 90°. And / or, the second sliding seat 22 is provided with a fourth limiting portion 222. This fourth limiting portion 222 includes two fourth limiting sub-parts 2221 extending along the first direction X1, and the two fourth limiting sub-parts 2221 are spaced apart along a third direction X3 on the second sliding inclined surface 221. On the third direction X3, the distance between the two fourth limiting sub-parts 2221 is the same as the size of the mounting base 3, that is, the distance between the two fourth limiting sub-parts 2221 is the same as the width of the mounting base 3.
[0053] With the above configuration, when the mounting base 3 is placed on the first sliding base 21 and the second sliding base 22, the two opposite sidewalls of the mounting base 3 in the third direction X3 will abut against the two third limiting sub-parts 2121 and / or the two fourth limiting sub-parts 2221 respectively. This can limit the mounting base 3 in the third direction X3, prevent the mounting base 3 from shifting during movement, and improve the stability of the mounting base 3 during movement.
[0054] In some embodiments, combined with Figures 1 to 4 As shown, the first sliding seat 21 has a first through hole 213 along the second direction X2, and the second sliding seat 22 has a second through hole 223 along the second direction X2. The bearing seat 100 also includes a first fixing member 61 and a second fixing member 62. The first fixing member 61 passes through both the mounting seat 3 and the first through hole 213 along the second direction X2, and is connected to the substrate 1, for example, in a fixed connection. The second fixing member 62 passes through both the mounting seat 3 and the second through hole 223 along the second direction X2, and is connected to the substrate 1, for example, in a fixed connection. Meanwhile, in the first direction X1, the size of the first through hole 213 is larger than the size of the first fixing member 61, and the size of the second through hole 223 is larger than the size of the second fixing member 62.
[0055] The above-described configuration allows the mounting base 3, the first sliding seat 21, and the second sliding seat 22 to be fixed to the base plate 1 using the first fixing member 61 and the second fixing member 62, thereby improving the stability of the bearing seat 100 during use. Simultaneously, by setting the size of the first through hole 213 in the first direction X1 to be larger than the size of the first fixing member 61 in the first direction X1, and setting the size of the second through hole 223 in the first direction X1 to be larger than the size of the second fixing member 62 in the first direction X1, it is possible to ensure that the first fixing member 61 and the second fixing member 62 can fix the mounting base 3, the first sliding seat 21, and the second sliding seat 22 while ensuring that the first sliding seat 21 and the second sliding seat 22 can move normally along the first direction X1.
[0056] For example, combined Figure 1 , Figure 2 , Figure 4 As shown, a third through hole 33 and a fourth through hole 34 are provided on the mounting base 3 along the second direction X2. The center line of the third through hole 33 coincides with the center line of the first through hole 213, and the center line of the fourth through hole 34 coincides with the center line of the second through hole 223. The first fixing member 61 passes through the third through hole 33 and is adapted to the third through hole 33, that is, the outer diameter of the first fixing member 61 is the same as the inner diameter of the third through hole 33. The second fixing member 62 passes through the fourth through hole 34 and is adapted to the fourth through hole 34, that is, the outer diameter of the second fixing member 62 is the same as the inner diameter of the fourth through hole 34. With this arrangement, the mounting base 3, the first sliding seat 21, and the second sliding seat 22 can be fixed while ensuring that the first sliding seat 21 and the second sliding seat 22 can move normally along the first direction X1. The structure is simple and easy to use.
[0057] On the other hand, such as Figure 5As shown, this embodiment provides a transmission structure, which includes a first transmission shaft 101, a second transmission shaft 102, and a bearing housing 100 as described in any of the above embodiments. The first transmission shaft 101 and the second transmission shaft 102 are connected in a transmission manner, and the axis of the first transmission shaft 101 is perpendicular to the axis of the second transmission shaft 102. Exemplarily, a first bevel gear 1011 is provided at one end of the first transmission shaft 101 near the second transmission shaft 102, and a second bevel gear 1021 is provided at one end of the second transmission shaft 102 near the first transmission shaft 101. The first bevel gear 1011 and the second bevel gear 1021 are adapted to each other. It is easy to understand that the adaptation of the first bevel gear 1011 and the second bevel gear 1021 here means that: the large-end module and pressure angle of the first bevel gear 1011 and the second bevel gear 1021 are equal; the cone angles of the first bevel gear 1011 and the second bevel gear 1021 are complementary; and the cone moments of the first bevel gear 1011 and the second bevel gear 1021 are equal. The first drive shaft 101 is mounted on the bearing housing 100, and / or the second drive shaft 102 is mounted on the bearing housing 100.
[0058] With this configuration, the height of the first drive shaft 101 and / or the height of the second drive shaft 102 can be adjusted using the bearing housing 100. This allows for adaptive adjustment of the relative positions of the first drive shaft 101 and the second drive shaft 102 according to actual operating conditions, avoiding large positional deviations between the first drive shaft 101 and the second drive shaft 102, ensuring the stability of power transmission, and improving the practicality and reliability of the aforementioned transmission structure during use.
