Analysis of the force condition of each part of the jaw crusher

Among all the parts of the equipment, the jaw plate, eccentric shaft and bearings are the ones that require high strength, and these parts are subjected to large load capacity during operation. Let's take a look at the force analysis of these main parts during work.

1. Force analysis of the jaw crusher bearing. Jaw crusher bearings are subjected to large axial vibration loads and certain radial vibration loads during operation, so the bearings of the jaw crusher are often used with self-aligning performance and double-row radial spherical roller bearings that can carry large capacity.

2. Force analysis of the jaw plate. During the operation of a jaw crusher, the movement of the boredom in the crushing chamber is very complex. The force on the jaw plate is influenced by the material feed state, the eccentric shaft speed of the crusher, the size of the discharge opening and other factors. During the crushing process of the jaw crusher, most of the material is concentrated in the middle of the crushing cavity, and the upper and lower part of the material is relatively small. Therefore, the force on the jaw plate is the largest in the middle of the horizontal direction, and the force on both sides is smaller, and the force on both sides is symmetrical.

3. Analysis of the force on the eccentric shaft of the jaw crusher. The maximum stress on the eccentric shaft of the jaw crusher is located at the edge of the shaft items of the two bearings of the eccentric shaft linkage. The level of stress at the two ends of the eccentric shaft is lower and the stress values in the surrounding directions are comparable. When the jaw crusher is in operation, the structure of the crusher and the condition of the crushing force determine the force condition of the eccentric shaft support point, which is variable in both force and moment, and the maximum crushing force of the jaw crusher and the maximum stress place of the eccentric shaft.

Jaw crusher is the most commonly used machine in ore equipment, its importance is self-evident. The above points are the force analysis of several important parts of the jaw crusher, which can help you better understand the jaw crusher and play a reference role for the majority of customers, helping them to produce high quality and qualified products efficiently and quickly.
