The Drive Devices Of Jaw Crusher

In the process of the jaw crusher broken homework transmission device is crucial, transmission device including eccentric shaft, connecting rod and thrust plate. Below Shibang machine introduces jaw crusher drive in turn.

1. The drive devices of Jaw crusher- Eccentric shaft

Jaw crusher eccentric shaft is made up and down movement of the main driving connecting rod parts. Large and medium-sized crusher eccentric shaft is usually made of alloy steel, small crusher can adopt quality carbon steel manufacturing. Axis adopts alloy steel or high quality carbon steel manufacturing.

Part of the suspension of eccentric shaft connecting rod, at both ends of the eccentric shaft are respectively equipped with flywheel and belt wheel, belt wheel besides acting as the transmission, but also fly wheel and role. They have larger diameter and quality, the role is to promote the crusher stable running, and uniform dynamic load.

2. The drive devices of Jaw crusher- Connecting rod

Most of connecting rod manufactured cast steel. Connecting rod to do up and down, in order to reduce the inertia force, should reduce the quality of the connecting rod as far as possible, so a section at the bottom of the connecting rod is often made into h, cross or box structure. The state machine of the connecting rod body with overall and combination, the former is suitable for medium and small crusher, the latter is applicable to large crusher.

3. The drive devices of Jaw crusher- The thrust plate

Thrust plate is connected connecting rod, moving jaw and frame connected component, plays the role of a transmission link force. The role of thrust plate to work under pressure, usually made of cast iron cast integral, also has made combined. The motion of the thrust plate has a certain Angle, It with other parts connected by live hinge, internal Mosaic have easy to replace the bushing.

In order to reduce the thrust plate and thrust and its bearing wear and tear, in addition to often in junction with lubricant, prevent the dust and fine grained material into the junction, so at the junction of the upper should add grey board.
