Embodiment 1

[0032] Such as Figure 1~2As shown, in this embodiment, in order to be able to measure the actual maximum torque of a motor at different speeds using simple conditions and low cost without a torque measuring instrument and a torque sensor, and without the need for different motor test structures Complicated modifications can better meet the experimental needs of general small businesses and schools. The measuring device for the actual maximum torque of the motor includes a mounting assembly 100 , a transmission mechanism 200 and a weight component 300 . Specifically, the installation assembly 100 is used to install and fix the measured motor, the input end of the transmission mechanism 200 is connected to the measured motor, and the output end is connected to the pulley block 201 for transmitting the rotational motion of the measured motor to the pulley block 201, The weight component 300 is connected to the output end of the transmission mechanism 200, and is suspended below ...

Embodiment 2

[0034] Such as Figure 3-4 As shown, in order to realize that the motor transmission mechanism 200 converts the rotational motion of the measured motor into the reciprocating motion of the weight component 300 in the vertical direction, the difference between this embodiment and the first embodiment is that the transmission mechanism 200 also includes a transmission part 202 , a bearing seat 203 , a handwheel 204 , a “U” groove bearing 205 and a coupling 206 . Specifically, the measuring device for the actual maximum torque of the motor includes a mounting assembly 100 , a transmission mechanism 200 and a weight component 300 . Wherein the installation assembly 100 is used for the installation and fixing of the measured motor, the input end of the transmission mechanism 200 is connected to the measured motor, and the output end is connected to the pulley block 201, and is used to transmit the rotational motion of the measured motor to the pulley block 201, and the weight compo...

Embodiment 3

[0037] refer to Figure 5-6 In this embodiment, in order to divert the movement mode of the measured motor and use several pulleys to effectively reduce the weight of the heavy object, it is convenient to increase or decrease the mass of the weight box when measuring the maximum torque of the motor. It is also possible to reduce the weight of the heavy object And increase the stability and balance of the structure. The difference between this embodiment and the second embodiment is: the device also includes a fixed pulley block 201a and a double row pulley 201b. Specifically, the measuring device for the actual maximum torque of the motor includes a mounting assembly 100 , a transmission mechanism 200 and a weight component 300 . Wherein the installation assembly 100 is used for the installation and fixing of the measured motor, the input end of the transmission mechanism 200 is connected to the measured motor, and the output end is connected to the pulley block 201, and is u...

Abstract

The invention discloses a device and a method for measuring the actual maximum torque of a motor. The device comprises a mounting assembly, which is used for installing the measured motor; a transmission mechanism, wherein the input end of the transmission mechanism is connected with the measured motor, and the output end is connected with the pulley block and, the transmission mechanism is used for driving the rotary motion of the measured motor to be transmitted into the pulley block; a weight part, which is connected with the output end of the transmission mechanism and is suspended below the pulley block. The invention has the beneficial effects that the supporting component, the transmission component, the pulley block and the weight part are ingeniously matched; measurement of the ultimate torques of the motor at different speeds is realized with the simple device and at a low cost in a limited condition; high-cost equipment such as a torque measuring instrument, a torque sensorand the like is not needed; complicated modification does not need to be carried out on different motor test structures, and the requirements of general small enterprises and school experiments can bewell met.

Description

technical field [0001] The invention relates to the technical field of motor torque testing, in particular to a measuring device for the actual maximum torque of a motor and a measuring method based on the device. Background technique [0002] In recent years, motors have been widely used in various driving devices, such as: trolley drive, conveyor belt drive, mine hoist, electric stair climbing wheelchair, bionic robot and robot arm drive, etc. In the motor-driven electric stair climbing wheelchair, the torque is the key to the selection of the motor, and it is the standard for the limit of the load at a certain speed. Therefore it is necessary to measure the actual maximum torque of a motor. At present, the motor torque is tested by means of a torque measuring instrument. The professional measuring equipment has a complex structure and high cost, and it is complicated to change the test structure of different motors. Generally, experiments done by small businesses and sc...
