What is the material and function of the jaw crusher bearing housing?

October 23, 2024
1007
The material of the jaw crusher bearing housing is mainly cast steel and forged billet. Cast steel has sufficient strength and rigidity to withstand the huge reaction force during the crushing process and ensure the stable operation of the machine. The heavy eccentric shaft is processed with forged billet, which further improves the reliability and durability of the jaw crusher.
 
The role of the bearing housing
The  bearing housing plays a vital role in the jaw crusher, mainly including the following aspects:
 
‌ Support and fix the bearing ‌: The bearing housing effectively supports and fixes the bearing through its structural design to ensure the stability and precision of the bearing during operation.
‌ Transmit power ‌: The bearing housing effectively transmits power through its structural design to ensure that the rotation of the eccentric shaft can be smoothly converted into the crushing force of the crusher.
‌ Protect the machine ‌: Under abnormal circumstances, such as when the crushing chamber falls into non-crushed materials, the bearing seat can play a certain protective role to prevent other parts of the machine from being damaged.
 
The working principle and maintenance method of the bearing housing
The working principle of the bearing housing is mainly to ensure the stability and precision of the bearing during operation through its structural design. Maintenance methods include regularly checking the tightness of the bearing housing to ensure that the coaxiality error with the eccentric shaft is within the allowable range to avoid uneven load and heating problems caused by the error. In addition, regular lubrication of the bearing seat and checking its wear are also necessary maintenance measures.
