Description

Technical Field

[0001] This utility model relates to the field of no-load detection of speed reducers, and in particular to a transmission cooperation structure between a speed reducer and a drive motor. Background Technology

[0002] Existing speed reducers undergo no-load testing before leaving the factory to check their vibration and noise levels under no-load conditions. Currently, this no-load testing requires connecting the speed reducer to the drive motor so that the motor can operate it under no-load conditions. The speed reducer is typically connected to the drive motor via keys, couplings, or bolts. This connection and disconnection process is time-consuming and labor-intensive for testing personnel. When performing no-load testing on large batches of speed reducers, this connection and disconnection process severely restricts testing efficiency, resulting in low testing overall efficiency.

[0003] In view of the above problems, it is necessary to study a transmission cooperation structure between the reducer and the drive motor, which can help improve the efficiency of no-load testing of the reducer. Utility Model Content

[0004] The purpose of this invention is to provide a transmission and engagement structure between a speed reducer and a drive motor, which helps to improve the efficiency of no-load testing of the speed reducer.

[0005] To achieve the above objectives, the solution of this utility model is: A transmission connection structure for a speed reducer and a drive motor includes a testing machine, a speed reducer, a drive motor, an input shaft connector, and an output shaft connector. The testing machine is fitted with a positioning fixture. The speed reducer and the positioning fixture are movably positioned together. The drive motor is mounted on the testing machine and located above the positioning fixture. The input shaft connector is detachably connected to the input shaft of the speed reducer. The input shaft connector has a rotating rod, which is symmetrically arranged about the input shaft of the speed reducer and perpendicular to the input shaft of the speed reducer. The output shaft connector is drively connected to the output shaft of the drive motor. The output shaft connector is located above the positioning fixture and has two symmetrically arranged and spaced transmission rods, which abut against the two sides of the rotating rod.

[0006] The input shaft connector is inserted into the input shaft of the reducer and is also engaged with the circumferential limiting mechanism.

[0007] The input shaft connector and the input shaft of the reducer are tightly bound together by a clamp.

[0008] The output shaft of the drive motor is fixedly fitted with a connecting flange, and the output shaft connector is locked to the connecting flange by bolts.

[0009] The transmission rod is equipped with a rotatable rotating sleeve, which is used to abut against the rotating rod.

[0010] The rotating sleeve is made of polyurethane.

[0011] The positioning fixture is detachably connected to the testing machine.

[0012] The positioning fixture is locked to the testing machine with bolts.

[0013] The positioning fixture is provided with a positioning slot, which is used for the speed reducer to be inserted and to cooperate with the speed reducer in a circumferential limiting manner.

[0014] The bottom of the positioning slot is provided with a clearance hole.

[0015] With the above solution, when performing no-load testing on the reducer, the testing personnel simply place the reducer, pre-installed with the input shaft connector, onto the positioning fixture and position it in place before performing the no-load test. During the no-load test, the drive motor drives the output shaft connector to rotate, and the two transmission rods of the output shaft connector abut against the sides of the rotating rod, forming a circumferential limiting engagement. This rotation of the output shaft connector causes the input shaft connector to rotate, thus changing the direction of the reducer's input shaft and bringing the reducer into a no-load state. After the no-load test is completed, the testing personnel can simply remove the reducer from the positioning fixture. As can be seen from the above, the testing personnel do not need to connect and disconnect the reducer from the drive motor; during no-load testing, they only need to place and remove the reducer, simplifying the operation and improving the efficiency of no-load testing. Moreover, the connection and disconnection of the input shaft connector and the drive motor can be performed simultaneously with the no-load test without affecting its efficiency.

Hoop. Detailed Implementation

[0023] To further explain the technical solution of this utility model, the following detailed description is provided through specific embodiments.

[0024] like Figures 1 to 6 As shown, this utility model discloses a transmission and engagement structure between a speed reducer 2 and a drive motor 3, which includes a testing machine base 1, a speed reducer 2, a drive motor 3, an input shaft connector 4, and an output shaft connector 5. The testing machine base 1 is fitted with a positioning fixture 11. The speed reducer 2 is movably positioned with the positioning fixture 11. The drive motor 3 is mounted on the testing machine base 1 and located above the positioning fixture 11. The input shaft connector 4 is detachably connected to the input shaft 21 of the speed reducer 2. The input shaft connector 4 has a rotating rod 41, which is symmetrically arranged about the input shaft 21 of the speed reducer 2 and perpendicular to the input shaft 21 of the speed reducer 2. The output shaft connector 5 is transmissionally connected to the output shaft 31 of the drive motor 3. The output shaft connector 5 is located above the positioning fixture 11 and has two symmetrically arranged and mutually separated transmission rods 51, which abut against the sides of the rotating rod 41.

[0025] When performing a no-load test on the reducer 2, the tester places the reducer 2, which has been pre-installed with the input shaft connector 4, onto the positioning fixture 11 and positions it in place. Then, the no-load test is performed. During the no-load test, the drive motor 3 drives the output shaft connector 5 to rotate, and the two transmission rods 51 of the output shaft connector 5 abut against the sides of the rotating rod 41 to form a circumferential limiting fit with the rotating rod 41. In this way, the rotation of the output shaft connector 5 will drive the input shaft connector 4 to rotate, causing the input shaft 21 of the reducer 2 to turn, thus putting the reducer 2 into a no-load state. After the no-load test is completed, the tester can simply remove the reducer 2 from the positioning fixture 11. As can be seen from the foregoing, the testing personnel do not need to connect and disconnect the reducer 2 and the drive motor 3. When conducting no-load testing, they only need to place the reducer 2 and remove the reducer 2, which simplifies the operation of the testing personnel and helps to improve the efficiency of no-load testing of the reducer 2. Moreover, the connection and disconnection of the input shaft connector 4 and the drive motor 3 can be carried out at the same time as the no-load testing, without affecting the efficiency of no-load testing.

[0026] In this embodiment of the invention, the input shaft connector 4 is plugged into the input shaft 21 of the reducer 2 and is also fitted with a circumferential limiting device; thus, the connection between the input shaft connector 4 and the reducer 2 is simple and the input shaft connector 4 can drive the input shaft 21 of the reducer 2 to rotate. Furthermore, the input shaft connector 4 and the input shaft 21 of the reducer 2 can be tightly bound together by the clamp 7 to prevent the input shaft connector 4 from loosening.

[0027] In an embodiment of this utility model, the output shaft 31 of the drive motor 3 is fixedly fitted with a connecting flange 6, and the output shaft connector 5 is locked to the connecting flange 6 by bolts, so that the output shaft connector 5 and the drive motor 3 are securely connected.

[0028] In an embodiment of this utility model, the transmission rod 51 of the output shaft connector 5 is provided with a rotatable rotating sleeve 511. The rotating sleeve 511 is used to abut against the rotating rod 41. The rotating sleeve 511 can rotate, which helps to reduce the wear of the rotating rod 41. The material of the rotating sleeve 511 can be polyurethane. The rotating sleeve 511 is rotatably mounted on the transmission rod 51 through a bearing.

[0029] In this embodiment of the invention, the positioning fixture 11 is detachably connected to the testing machine 1. Specifically, the positioning fixture 11 can be locked to the testing machine 1 with bolts. With this configuration, the invention can select the appropriate positioning fixture 11 for installation according to different models of reducers 2. The positioning fixture 11 may be provided with a positioning slot 111, which is used for the insertion of the reducer 2 and for circumferential limiting cooperation with the reducer 2. The bottom of the positioning slot 111 is provided with a clearance hole 1111 to allow space for the output shaft 22 of the reducer 2.

[0030] The above embodiments and figures are not intended to limit the product form and style of this utility model. Any appropriate changes or modifications made by those skilled in the art should be considered as not departing from the patent scope of this utility model.
