Description

Technical Field

[0001] This utility model relates to the field of speed reducer testing technology, and in particular to a speed reducer break-in equipment. Background Technology

[0002] As a core component of industrial transmission systems, speed reducers require necessary break-in tests after assembly to eliminate problems such as machining errors, assembly stress, and surface burrs, ensuring the meshing accuracy and operational stability of key components such as gear pairs and bearings.

[0003] Most existing testing equipment adopts a single-unit, sequential testing mode, allowing only one gearbox to be installed and tested at a time. After the equipment is started, a preset break-in period (which may range from tens of minutes to several hours) must be completed before the tested gearbox can be disassembled and the next gearbox to be tested can be installed. When facing the demands of mass production, a large number of testing equipment and operators are required, occupying a significant amount of production space. This not only significantly increases production costs (equipment purchase, maintenance, energy consumption, and labor costs) but also greatly extends the overall product production and delivery cycle, failing to meet the efficiency requirements of modern large-scale production. Utility Model Content

[0004] The main purpose of this invention is to propose a speed reducer break-in device, which aims to solve the problem that existing testing equipment cannot test multiple speed reducers simultaneously.

[0005] To achieve the above objectives, the present invention proposes a speed reducer break-in device, which includes:

[0006] The workbench is equipped with multiple test stations at intervals, and the test stations are used to place the speed reducers to be tested;

[0007] A synchronous transmission mechanism includes a plurality of spaced-apart synchronous pulleys, each of which is correspondingly connected to the input shaft of a speed reducer, and the synchronous pulleys are fixedly connected to the input shaft; and

[0008] A drive mechanism is mounted on the workbench. The drive mechanism is used to drive the synchronous rotation of multiple synchronous pulleys, so as to drive the input shafts on multiple reducers to rotate simultaneously.

[0009] In one embodiment, the synchronous transmission mechanism further includes:

[0010] The drive wheel is coaxially and fixedly connected to the output shaft of the drive mechanism;

[0011] A timing belt is wound around the drive pulley and the plurality of timing pulleys to synchronously connect the drive pulley and the plurality of timing pulleys.

[0012] In one embodiment, the synchronous belt has an upper section and a lower section connected end to end, the upper section being connected to the synchronous pulley; the synchronous transmission mechanism further includes a driven pulley, the driven pulley being disposed away from the driving pulley, and a plurality of the synchronous pulleys being disposed between the driven pulley and the driving pulley, and the driven pulley supporting the lower section of the belt in a direction away from the synchronous pulley, so that the lower section of the belt is disengaged from the synchronous pulley.

[0013] In one embodiment, the synchronous transmission mechanism further includes a tensioning wheel, which is located above the synchronous wheel and abuts against the upper belt, such that the tensioning wheel and the synchronous wheel abut against the upper and lower sides of the upper belt, respectively.

[0014] In one embodiment, the speed reducer break-in equipment further includes a mounting plate, which is fixedly mounted on the workbench, and the synchronous transmission mechanism is rotatably mounted on the mounting plate.

[0015] In one embodiment, the speed reducer break-in equipment further includes a positioning mechanism, which is fixedly mounted on the mounting plate. The positioning mechanism has an internal accommodating space, and the input shaft of the speed reducer and the rotation shaft of the synchronous pulley are connected and fixed within the accommodating space.

[0016] In one embodiment, the speed reducer break-in equipment further includes a connecting mechanism, which is disposed within the accommodating space and connects the input shaft of the speed reducer and the synchronous pulley.

[0017] In one embodiment, the connecting mechanism includes a coupling disposed within the accommodating space, with one end of the coupling connected to the input shaft of the reducer and the other end connected to the rotating shaft of the synchronous pulley.

[0018] In one embodiment, the inner wall of the coupling is provided with a limiting groove; the connecting mechanism further includes a bushing, which is sleeved on the outer periphery of the input shaft of the reducer, the bushing is embedded in the limiting groove, and the shape of the limiting groove is adapted to the shape of the bushing.

[0019] In one embodiment, the speed reducer break-in equipment further includes a pressing mechanism, which is disposed on the worktable and abuts against the speed reducer to press the speed reducer toward the synchronous transmission mechanism.

[0020] This invention provides a technical solution by setting multiple test stations on a workbench, which can accommodate multiple speed reducers. The synchronous transmission mechanism includes multiple spaced synchronous pulleys, fixing the input shaft of each speed reducer to its corresponding driven synchronous pulley. A single drive mechanism simultaneously drives the synchronous rotation of multiple synchronous pulleys, thereby driving multiple speed reducers to operate synchronously, allowing the break-in tests of multiple speed reducers to be performed in parallel. Compared to the traditional solution where each speed reducer is equipped with an independent drive system, this solution can significantly shorten the testing cycle and effectively improve testing efficiency.

[0032] Most existing testing equipment adopts a single-unit, sequential testing mode, allowing only one gearbox to be installed and tested at a time. After the equipment is started, a preset break-in period (which may range from tens of minutes to several hours) must be completed before the tested gearbox can be disassembled and the next gearbox to be tested can be installed. When facing the demands of mass production, a large number of testing equipment and operators are required, occupying a significant amount of production space. This not only significantly increases production costs (equipment purchase, maintenance, energy consumption, and labor costs) but also greatly extends the overall product production and delivery cycle, failing to meet the efficiency requirements of modern large-scale production.

[0033] This utility model proposes a speed reducer break-in device.

[0034] Please see Figure 1 In one embodiment of this utility model, the speed reducer break-in device 100 includes:

[0035] Workbench 1 is equipped with multiple test stations at intervals. The test stations are used to place the reducer 01 to be tested.

[0036] The synchronous transmission mechanism 2 includes a plurality of spaced synchronous pulleys 21, each synchronous pulley 21 being connected to the input shaft of a reducer 01, and the synchronous pulley 21 being fixedly connected to the input shaft; and

[0037] The drive mechanism 3 is mounted on the workbench 1. The drive mechanism 3 is used to drive the synchronous rotation of multiple synchronous pulleys 21, so as to drive the input shafts on multiple reducers 01 to rotate simultaneously.

[0038] The technical solution of this utility model involves setting multiple test stations on the workbench 1, which can be used to place multiple speed reducers 01. The synchronous transmission mechanism 2 includes multiple spaced synchronous pulleys 21, which fix the input shaft of each speed reducer 01 to the corresponding driven synchronous pulley 21. A single drive mechanism 3 simultaneously drives the synchronous rotation of multiple synchronous pulleys 21, thereby driving multiple speed reducers 01 to operate synchronously, allowing the break-in tests of multiple speed reducers 01 to be performed in parallel. Compared with the traditional solution where each speed reducer 01 is equipped with an independent drive system, this solution can greatly shorten the test cycle and effectively improve test efficiency.

[0039] Specifically, the workbench 1 can be a square or round plate made of metal. Multiple vertical partitions can be installed on the workbench 1 at certain intervals to form multiple independent test spaces, allowing the reducer 01 to be tested independently at each test station. Furthermore, the test stations on the workbench 1 can also be provided with positioning holes or slots for fixing the reducer 01. The shape of the test stations is not specifically limited, as long as it is a shape that fits the mounting base of the reducer 01. The structure of the synchronous transmission mechanism 2 is not specifically limited; for example, it can include multiple synchronous pulleys 21 and one (or more, depending on the layout) synchronous belt 23. The synchronous pulleys 21 are wheels with equidistant teeth, and the synchronous belt 23 is an annular belt with equidistant teeth on its inner surface. The drive mechanism 3 can be directly connected to one drive pulley 22, with the rest being synchronous pulleys 21. Each synchronous pulley 21 is connected to the input shaft of a reducer 01, and the synchronous belt 23 surrounds all the synchronous pulleys 21 to ensure tooth meshing. The drive mechanism 3 can be a servo motor, a frequency converter motor, or a regular asynchronous motor, and its output shaft can be fixedly connected to a drive wheel 22.

[0040] The specific working principle is as follows: Multiple speed reducers 01 to be tested are placed on various test stations of the workbench 1 and fixed with bolts or other fasteners. The input shaft of each speed reducer 01 is fixedly connected to the corresponding driven synchronous pulley 21. For example, keyways are machined on the input shaft and the hub of the synchronous pulley 21, a flat key is inserted and tightened with a nut, or an expansion sleeve is used to ensure that both rotate synchronously without relative slippage. Additionally, the drive mechanism 3 is installed near the speed reducer 01 so that the output shaft of the drive mechanism 3 can be driven to connect with multiple synchronous pulleys 21 in the synchronous transmission mechanism 2, thereby driving the input shafts of the multiple speed reducers 01 to rotate synchronously.

[0041] In the embodiments of this utility model, please refer to Figure 1 and Figure 2 The synchronous transmission mechanism 2 also includes:

[0042] The drive wheel 22 is coaxially and fixedly connected to the output shaft of the drive mechanism 3;

[0043] A timing belt 23 is wound around the drive pulley 22 and multiple timing pulleys 21 to synchronously connect the drive pulley 22 and multiple timing pulleys 21.

[0044] Specifically, in this design, the drive pulley 22 is fixedly connected to the output shaft of the drive mechanism 3 via a tensioning sleeve or keyway to ensure no slippage. A timing belt 23 is fitted over all the timing pulleys 21 and the drive pulley 22, and tensioned to a suitable preload using a tensioning mechanism (such as adjusting the motor mounting position or using a tensioning pulley 25) to ensure good meshing between the teeth, effectively transmitting power without excessive wear due to overtightness. Each timing pulley 21 corresponds to the input shaft of a reducer 01, and its specifications must match those of the drive pulley 22 and the timing belt 23. The timing pulleys 21 can be mounted on independent brackets, which are bolted to the worktable 1 to ensure stable positioning. Assuming four test stations are located on the worktable 1, there are four corresponding timing pulleys 21. The timing pulleys 21 can be made of polyurethane. To accommodate possible minor center distance differences or installation errors, different numbers of teeth can be selected, but it must be ensured that they match the timing belt 23.

[0045] In the embodiments of this utility model, please refer to Figure 2The synchronous belt 23 has an upper section 231 and a lower section 232 connected end to end. The upper section 231 is connected to the synchronous pulley 21. The synchronous transmission mechanism 2 also includes a driven pulley 24, which is positioned away from the driving pulley 22. Multiple synchronous pulleys 21 are positioned between the driven pulley 24 and the driving pulley 22. The driven pulley 24 supports the lower section 232 in a direction away from the synchronous pulley 21, so that the lower section 232 is disengaged from the synchronous pulley 21. The driven pulley 24 can be mounted on the worktable 1 via bearings. Multiple synchronous pulleys 21 are spaced apart between the driven pulley 24 and the driving pulley 22. The first synchronous pulley 21 is positioned close to the driving pulley 22, and the last synchronous pulley 21 is positioned close to the driven pulley 24. The arrangement of the driven pulley 24 can reduce the wrap angle of the synchronous belt 23 at the last synchronous pulley 21 and support the lower section 232 to disengage from the lower side of the synchronous pulley 21, avoiding interference that would affect the rotation of the synchronous belt 23. The synchronous belt 23 engages with the drive pulley 22, each synchronous pulley 21, and the driven pulley 24 through toothed meshing, ensuring that the rotation of the drive pulley 22 can be accurately and synchronously transmitted to each synchronous pulley 21.

[0046] In the embodiments of this utility model, please refer to Figure 2 The synchronous transmission mechanism 2 also includes a tensioning pulley 25, which is positioned above the synchronous pulley 21 and abuts against the upper belt 231, such that the tensioning pulley 25 and the synchronous pulley 21 abut against the upper and lower sides of the upper belt 231, respectively. The tensioning pulley 25 may include a hub with teeth on the synchronous belt 23, a support bearing, an adjustment mechanism, and a housing. The adjustment mechanism can be a spring-tensioned mechanism, where a constant thrust is provided by compressing a spring to push the tensioning pulley 25 against the synchronous belt 23. The spring force can be set by adjusting the spring preload or by replacing the spring with one of different stiffness. Alternatively, an eccentric bolt can be used for adjustment; by rotating the eccentric bolt, the position of the axis of the tensioning pulley 25 is changed, thereby adjusting its pressure on the synchronous belt 23. The addition of the tensioning pulley 25 creates a clamping structure of "synchronous pulley 21 (lower) - synchronous belt 23 - tensioning pulley 25 (upper)" in the region of the synchronous pulley 21, enhancing the stability and tension effect of the upper belt 231 in the region of the synchronous pulley 21.

[0047] In the embodiments of this utility model, please refer to Figure 2 The reducer break-in equipment 100 also includes a mounting plate 4, which is fixedly mounted on the worktable 1. The synchronous transmission mechanism 2 is rotatably mounted on the mounting plate 4. The material of the mounting plate 4 is not specifically limited; for example, it can be a steel plate or a glass plate. Mounting holes (threaded holes or smooth holes for bolts) can be machined on the mounting plate 4 at the positions corresponding to the driving wheel 22, synchronous wheel 21, driven wheel 24, and tensioning wheel. The mounting plate 4 can be fastened to the pre-embedded bolts or a special mounting base on the top of the worktable 1 using multiple high-strength bolts. To prevent loosening, double nuts or spring washers can also be used.

[0048] In the embodiments of this utility model, please refer to Figure 1 and Figure 4 The speed reducer break-in equipment 100 also includes a positioning mechanism 5, which is fixedly mounted on the mounting plate 4. The interior of the positioning mechanism 5 forms an accommodating space 50, within which the input shaft of the speed reducer 01 and the rotating shaft of the synchronous pulley 21 are connected and fixed. The positioning mechanism 5 can be designed as an L-shape or have an open surface, allowing the user to push the input shaft of the speed reducer 01 in from the side or front, and insert the rotating shaft of the synchronous pulley 21 from the opposite side, achieving alignment and connection. After completion, the clamping mechanism 7 clamps the housing of the speed reducer 01. If maintenance or removal of the speed reducer 01 is required, simply loosen the clamping mechanism 7, and possibly also loosen a fastener on the positioning mechanism 5 (such as a cover plate screw), to easily remove the speed reducer 01. In other embodiments, the positioning mechanism 5 can also consist of a fixing frame 51 and a positioning plate 52, which together form an open accommodating space 50, reserving connection space for the input shaft of the speed reducer 01 and the rotating shaft of the synchronous pulley 21.

[0049] In the embodiments of this utility model, please refer to Figure 3 The speed reducer break-in equipment 100 also includes a connecting mechanism 6, which is located within the accommodating space 50 and connects the input shaft of the speed reducer 01 and the synchronous pulley 21. The type of connecting mechanism 6 is not specifically limited; for example, it can be a key connection or a flange connection. In one embodiment, when using a key connection, keyways can be machined on the inner hole of the synchronous pulley 21 hub and the outer circle of the speed reducer 01 input shaft, respectively, to embed rectangular or flat keys. When using a flange connection, a flange can be provided at the end of the speed reducer 01 input shaft near the synchronous pulley 21, and a flange can also be provided at the end of the synchronous pulley 21 near the input shaft. The flanges on both are fastened together by bolts to achieve a coaxial fixed connection between the input shaft and the synchronous pulley 21.

[0050] In the embodiments of this utility model, please refer to Figure 4The connecting mechanism 6 includes a coupling 61, which is disposed within the accommodating space 50. One end of the coupling 61 is connected to the input shaft of the reducer 01, and the other end is connected to the rotating shaft of the synchronous pulley 21. The coupling 61 enables coaxial connection between the input shaft of the reducer 01 and the rotating shaft of the synchronous pulley 21. The coupling 61 can be a commonly used structure such as a flexible coupling 61 or a diaphragm coupling 61. In one embodiment, a flexible coupling 61 is used, comprising two half-couplings 61 with mounting holes and several pins with elastic sleeves (usually rubber or nylon). The two mounting holes are used to connect the input shaft of the reducer 01 and the rotating shaft of the synchronous pulley 21, respectively. The pins are located between the two half-couplings 61. Torque is transmitted to the pins through the half-couplings 61, and then from the pins to the other half-coupling 61. The elastic sleeves serve to buffer vibration and compensate for shaft misalignment. In another embodiment, a diaphragm coupling 61 is used, comprising two half-couplings 61, one or more sets of metal diaphragms (typically thin stainless steel sheets, polygonal or cross-shaped), and a bolt assembly. The diaphragms are connected to the two half-couplings 61 by bolts. Torque is transmitted to the diaphragms through the bolts, and the diaphragms compensate for axial deviations (radial, axial, angular) through their own elastic deformation, while simultaneously transmitting torque.

[0051] In the embodiments of this utility model, please refer to Figure 4 The coupling 61 has a limiting groove 611 on its inner wall. The connecting mechanism 6 also includes a bushing 62, which is sleeved on the outer circumference of the input shaft of the reducer 01. The bushing 62 is embedded in the limiting groove 611, and the shape of the limiting groove 611 matches the shape of the bushing 62. For example, the limiting groove 611 can be a hexagonal groove, and the bushing 62 has a hexagonal structure similar to a nut. The shape matching design of the bushing 62 and the limiting groove 611 can form a similar snap-fit ​​structure. The user only needs to align the input shaft of the reducer 01 with the bushing 62 with the coupling 61 and gently push it in. The bushing 62 will automatically embed into the limiting groove 611, reducing repeated adjustments and alignment checks during installation and improving installation efficiency. In one embodiment, a keyway can be provided on the outer wall of the input shaft, and a key-shaped protrusion can be provided inside the bushing 62 to facilitate the insertion of the bushing 62 into the input shaft.

[0052] In the embodiments of this utility model, please refer to Figure 1 and Figure 3The speed reducer break-in equipment 100 also includes a clamping mechanism 7, which is mounted on the worktable 1 and abuts against the speed reducer 01 to clamp the speed reducer 01 toward the synchronous transmission mechanism 2. In this embodiment, the clamping mechanism 7 may include a telescopic cylinder and a push rod fixedly connected to the piston rod of the cylinder. The telescopic cylinder is fixed on the worktable 1, and the extension and retraction of the piston rod drives the push rod to extend or retract, so as to clamp the speed reducer 01 onto the positioning mechanism 5 or disengage it from the positioning mechanism 5. Of course, in other embodiments, the clamping mechanism 7 may also include a base, a connecting member, a push rod, and a rotating handle, etc. The base is provided with a through hole, and the push rod passes through the through hole. One end of the push rod is hinged to a connecting member, and the connecting member is hinged to a rotating handle, which is hinged to the base. When it is necessary to clamp or release the reducer 01, simply move the rotating handle at a certain angle. Through the hinged connection, the push rod can move back and forth in the through hole, thereby clamping or releasing the reducer 01.

[0053] The above description is merely an exemplary embodiment of the present utility model and does not limit the scope of protection of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the scope of protection of the present utility model.
