[0002] The wear resistance test of rubber synchronous belts is an important part of evaluating their quality and service life. The following are some common wear resistance test methods for rubber synchronous belts: Friction and wear test principle: By making the synchronous belt move relative to a specific friction material to simulate the friction situation in actual use. For example, using a rotary friction testing machine, under certain pressure, speed and time conditions, measure the wear amount of the synchronous belt. Reciprocating wear test principle: Make the synchronous belt move reciprocally in a straight line direction to generate friction with the contact surface. For example, set a fixed stroke and frequency on the testing machine and observe the wear degree of the synchronous belt after multiple reciprocating movements.

One side of the moving frame two 28 is rotatably connected with a synchronous pulley two 29. The synchronous pulley two 29 and the synchronous pulley one 26 are tensioned and connected by a synchronous belt.

[0032] In this embodiment, first, the synchronous belt is sleeved on the side walls of the second synchronous pulley 29 and the first synchronous pulley 26. Then, rotating the knob 3 can drive the threaded rod 21 to rotate, so that the threaded rod 21 can drive the lifting plate 22 to move.
