Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, with reference to the accompanying drawing and implement
Example is described in further detail the utility model.It should be appreciated that specific embodiment described herein is only to explain this reality
With novel, it is not used to limit the utility model.
A kind of cogging torque test device of the utility model, as shown in Figs. 1-2, including workbench 1, motor mounting rack
2, line wheel 3, tensiometer 4 and p-wire 5 are tested, motor mounting rack 2 is arranged on workbench 1, is mounted on motor to measured motor 9
In mounting bracket 2, test line wheel 3 is mounted on the output shaft to measured motor 9, and p-wire 5 is in test line wheel 3, and one
End is connect with tensiometer 5.When measuring cogging torque, tensiometer 4 is slowly pulled, is recorded required when test line wheel 3 rotates
Power, measured by tensiometer 5.Then the torque of tooth socket is can be obtained into multiplied by the radius of test line wheel 3 in the pulling force measured.
In order to adapt to more motors, in one embodiment, is opened up on the desktop of workbench 1 and allow motor mounting rack
2 through-holes 11 passed through adjust the height of the prominent through-hole 11 of motor mounting rack 2 by regulating device 6, to meet various sizes electricity
In addition the installation of machine cooperates matching test line wheel 3 to measure.Specifically, regulating device 6 includes two guide parts
61, elevating mechanism 62 and actuator 63, motor mounting rack 2 are arranged on guide part 61 and elevating mechanism 62, and guide part 61 can
To be column, 2 vertical shift of motor mounting rack is used to support and guided；Elevating mechanism 62 can be screw rod, two screw rods with
Column is arranged in parallel, and distribution triangular in shape；Actuator 63 can be motor, and driving screw rod rotation makes motor installation branch
Frame 2 moves up and down vertically.
In the above-described embodiments, guide rail 7 is horizontally disposed on workbench 1, tensiometer 4 is arranged on guide rail 7, and 7, guide rail
Support and guidance tensiometer 7 are moved along the tangential direction of test line wheel 3.Due in the different sizes to measured motor 9 of replacement, needing pair
The position of motor mounting rack 2 is adjusted, and infrared transmitter 81 and infrared remote receiver 82, the two are also set up on workbench 1
It is arranged on the same line, and parallel with guide rail 7.When in use, the position of motor mounting rack 2 is adjusted by regulating device 6
It sets, the test line wheel 3 after being installed is in higher position, and infrared remote receiver 82 can receive the transmitting of infrared remote receiver 81
