Failure analysis and connection design of pumping unit crank pin

The utility model is composed of a land wheel, a driving pin, a driving crank arm, a driving inserted link, a release spring, and a driving ratchet.

它由地轮、传动销、传动拐臂、传动插杆、回位弹簧和传动棘轮组成。

The facility is operated by the driving of crank to keep a guide rod stable and overwork under high speed, Moreover, it is also available to4 pieces of heald frame according to density.

设备转动通过驱动曲柄来进行，配备导杆不会有颤动、且高速下可以超负荷运转。
