Description

Technical Field

[0001] This utility model belongs to the field of motor manufacturing technology, specifically relating to a motor performance testing platform. Background Technology

[0002] Geared motors reduce speed and increase torque by adding a reduction gear set to the motor output shaft. Different torque motors can be produced by designing different reduction gear sets. However, after the torque motor is produced, a torque test is required to ensure that the motor meets the rated torque design standard. However, the current torque testing equipment is relatively complicated, and the torque testing range is narrow with poor test compatibility. Utility Model Content

[0003] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0004] A motor performance testing platform includes a frame body and a motor section, a braking section, and a signal acquisition section mounted on the frame body. The signal acquisition section is located between the motor section and the braking section. The motor section and the signal acquisition section are connected by a first coupling, and the braking section and the signal acquisition section are connected by a second coupling.

[0005] The braking unit includes a housing, a brake disc disposed within the housing, and a drive element for driving the brake disc to move forward / backward. The housing also contains a friction disc, which is connected to a shaft within the second coupling.

[0006] Furthermore, the motor unit includes a motor under test and a fixing member for fixing the motor under test, and also includes a sliding member for driving the fixing member to move forward / backward.

[0007] Furthermore, the friction disc is provided with a plurality of first grooves, and wear-resistant blocks are provided in the first grooves. The wear-resistant blocks are detachably connected to the friction disc, and the top surface of the wear-resistant blocks is higher than the top surface of the friction disc.

[0008] Furthermore, the friction disc is provided with several second grooves, which are used to embed weight-adding blocks, the top surface of which is lower than the top surface of the wear-resistant block.

[0009] Furthermore, the fixing component includes a fixing base and a fixing block. The fixing block is detachably connected to the fixing base by a number of fasteners, and the motor under test is located between the fixing base and the fixing block.

[0010] Furthermore, the sliding component comprises a slider and a slide rail, with the slider connected to the fixed base and the slide rail connected to the frame body.

[0011] Furthermore, the driving element is a hydraulic cylinder.

[0012] The beneficial effects of this utility model are:

[0013] 1. This utility model connects the signal acquisition device and the braking unit in a coaxial series. By using a motor to drive the shaft to rotate, the torque under different motors can be tested. The braking unit provides different torque values ​​by driving the brake disc close to the friction disc through a hydraulic cylinder. Friction blocks are distributed on the friction disc for hard contact and can be replaced after long-term use. In order to facilitate the adjustment of different torque values, grooves for installing weight blocks are also provided on the friction disc to increase the mass of the friction disc and provide a wider torque range.

[0014] 2. The motor mounting end of this utility model uses a slide rail, which facilitates the fixing of motors with different gearboxes. The slide rail can be moved backward to match a longer motor, which has wider compatibility and a higher degree of matching.

In order to better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, the preferred embodiments of this utility model are described in detail below with reference to the accompanying drawings.
