Why are large and small gears of cone crushers failing?

There are five types of cone crushers, which can be divided into single-cylinder cone crusher, multi-cylinder cone crusher, Simmons cone crusher, compound cone crusher and spring cone crusher. The external and internal structures of the five have similarities and have certain differences. Differences, such as the bevel gears are the same and are important rotating parts. During the crushing operation of the cone crusher, all parts are indispensable and must be fault-free, otherwise normal work cannot be performed. This article shares with you the reasons for the frequent failure of the cone crusher bevel gears to help users effectively prevent the occurrence and occurrence of failures.

First, the cone crusher frequently passes iron and causes the bevel gear to fail
Each size of the cone crusher has applicable materials and parameters of a large feed opening. If the input materials do not comply with the crushing equipment, it will cause the equipment to fail to run or become jammed by foreign objects. This phenomenon is called iron crossing. Frequent and prolonged jamming of foreign objects leads to poor discharge or even blockage, increasing the load of the crusher and the motor, the gears are damaged and broken under huge load pressure, and the entire machine fails to operate.

The phenomenon of iron crushing in the cone crusher is very harmful to the entire machine. We can take two measures to prevent this phenomenon and protect the crusher. First, an iron-type device is added from the beginning to prevent foreign matter from entering the crusher cavity when transporting materials. Secondly, an automatic trip type device is added. If foreign matter enters the cavity and causes the crusher to overload, it can automatically cut off the power to protect the internal components of the crusher from the impact of pressure.

Second, the cone bevel gear clearance is too large or too small
When the large and small bevel gears of the cone crusher are not affected by external shocks, they can start from the component itself to make judgments and find out why. For example, during the installation process, the gear gap adjustment is too large and too small, and the tooth will be generated during the operation. Installation is the forefront step of a smooth operation. Be sure to make sure that the gear clearance is within the appropriate range.

In summary, the two reasons for the failure of the bevel gear of the conical crusher are explained above, and the bevel gear may be damaged due to insufficient lubrication and processing accuracy problems. After the crusher breaks down, users need to check it one by one.
