Embodiment 1
[0029] A bearing test device that can be loaded with alternating loads based on a synchronous belt transmission mechanism, such as figure 1 As shown, the device includes a computer 1, a driving motor 2, a coupling 3, a torque meter 4, a fixed fixture A 5, an oil supply system 6, an alternating load loading assembly 7, a movable fixture 8, a fixed fixture B 9, and a rotating shaft 10. Accompanying test bearing B 11, tested bearing B 12, tested bearing A 13, accompanying test bearing A 14, working platform 15. Among them, such as figure 2 As shown, the alternating load loading assembly 7 includes a temperature sensor 16, a rotating motor A 17, a synchronous belt transmission mechanism A 18, a spring A 19, a connection device A 20, a connection device B 21, a spring B 22, a timing belt transmission mechanism 23, Rotate motor B 24 . In this embodiment, the sliding bearing is mainly tested, which is composed of a bearing seat and a bearing bush embedded in the bearing seat with ...
Embodiment 2
[0035] A bearing test device that can be loaded with alternating loads based on a synchronous belt transmission mechanism, its structure is roughly the same as that of Embodiment 1, the difference is that in this embodiment, the driving wheel and the driven wheel are spur gears, which are connected to each other by a chain , the transmission effect is better.
