Description

Shock attenuation formula torque limiter one-way clutch with braked wheel

Technical Field

The utility model relates to a torque limiter field specifically is a shock attenuation formula torque limiter one way clutch with braked wheel.

Background

At present, limiters in various forms are widely applied to various devices, most limiters can only play a role in overload protection, namely when the torque of the devices exceeds a set value during operation, the devices are separated from driving and driven to idle, and damage to the devices due to overlarge torque is avoided. However, in many applications, the protection effect is not sufficient, for example, in some applications with large vibration, the vibration needs to be reduced by a damping device so as to prevent the device and the limiter from being damaged by excessive vibration.

It can thus be seen that there is a need in the art to provide a one-way clutch for a damped torque limiter having a brake wheel.

Furthermore, a threaded hole is formed in the shaft sleeve, a set screw penetrates through the threaded hole, and the shaft sleeve and the driven shaft are fixed through the set screw.

Furthermore, a plurality of threaded holes are formed in the tire elastic body in the radial direction, first inner hexagon screws penetrate through the threaded holes, and the tire elastic body and the shaft sleeve are fixed through the first inner hexagon screws.

Furthermore, the tire elastomer, the transition flange and the brake wheel are connected through a second inner hexagon screw.

Further, a check ring for a shaft and a check ring for a hole are arranged between the one-way clutch and the cover plate and between the one-way clutch and the transition flange.

Compared with the prior art, the utility model discloses following beneficial effect has:

the utility model discloses can realize playing the guard action after the moment of torsion transships, can also realize that the customer requires the folk prescription to transship and throw off protect function, simultaneously, adopt the high elasticity elastomer of tire formula, have better cushioning effect, can be used for vibrations great occasion like this again, and this product is equipped with the braked wheel, can play the braking action simultaneously again.
