The course of work for the speed changer test device that present embodiment provides is specific as follows:
Step S1: speed changer 2 is installed in speed changer test device, and speed changer 2 is placed in some to be measured
On gear, and locking is carried out to the first output end 21 by the first locking assembly 1, is exported by the second locking assembly 6 to second
End 23 carries out locking；
Step S2: input terminal 22 and torque wrench 31 are connected using connector 32；
Step S3: applying torque to torque wrench 31 along clockwise direction, until torque wrench 31 reaches preset torque
Stop when value 20Nm, and the angle value that input terminal 22 rotates is read by inclinometer 4；
Step S4: applying torque to torque wrench 31 in the counterclockwise direction again, until torque wrench 31 reaches preset power
Stop when square value 20Nm, and the angle value that input terminal 22 rotates is read by inclinometer 4；
Step S5: being repeated several times step S3 and step S4, and the angle value rotated to each input terminal 22 is averaged,
To obtain the speed changer 2 in a certain particular gears, torque wrench 31 applies the angle rotated under torque with input terminal 22
The respective value of value θ；
Step S6: successively changing the preset moment values of torque wrench 31 is 40Nm, 60Nm ..., and successively clockwise
Apply torque with counterclockwise, to obtain the speed changer 2 in a certain particular gears, under the application torque of torque wrench 31 with it is defeated
Enter the respective value of the angle value θ of 22 rotation of end.
The speed changer test device can be used for testing the gear backlash of speed changer 2, and the input terminal 22 of speed changer 2 rotates
Angle, θ can characterize gear backlash.Certain gear backlash is reserved, can avoid gear because operating fever expansion goes out
Existing stuck phenomenon improves movement transmitting accuracy, reduces the loss in movement transmittance process.Test the gear engagement of speed changer 2
Whether reasonable gap can fully understand the gear backlash, so that speed changer 2 plays optimum performance, improve the dynamic of automobile
