How to solve the abnormal sound and vibration of the hammer breaking transmission device?

The transmission is the power component of the hammer crusher . Once a problem occurs, the equipment will stop running, which will seriously affect the production efficiency. However, in the work, due to improper operation or neglect of daily maintenance, various problems will inevitably occur. Today we will talk about the hammering of the transmission.

Before we understand the fault, we need to know what the hammered drive contains, and its structure is as follows:

Some time ago, we analyzed the problem of bearing suspension of the hammer breaking transmission. Today, let us talk about why the transmission device has abnormal noise and vibration, and attach a solution.

Transmission abnormal sound

Due to the high-speed operation of the transmission for a long time, the oil seal is damaged, other impurities enter the bearing, and the lubrication is not timely, resulting in rust and slight pitting of the rolling elements. If you put it in the bearing seat hole with a metal rod, the other end into the ear, you will hear very obvious abnormal sound. At this time, it is necessary to stop the vehicle for maintenance and replace the bearing.

Large vibration of the transmission

When the short-axis bearing is in the normal state, the machine will emit a soft, uniform vibration sound. When the short-axis bearing is worn out and the clearance exceeds the standard, the vibration of the machine will increase. At this time, stop the vehicle for maintenance and replace the bearing. Since the short-shaft drive is driven by the belt, sometimes the tension of the belt is not well adjusted, which may also cause vibration of the transmission.

Troubleshooting method

Before the equipment is turned on, it is very important to do the inspection of the hammer break. For the transmission, the following three points should be eliminated:

1. When dismantling and repairing the transmission, it is necessary to strictly carry out the overhaul process and operate it carefully. When replacing bearings and seals, they must be carefully inspected by the quality inspector, and the dimensions of the shaft diameter and the bearing housing hole should be proofread.

2. When replacing the short shaft assembly, the installation size should be measured first to prevent problems in the assembly;

3. Carefully check the equipment during operation, find hidden troubles, eliminate in time, replace the grease on time, and ensure that the transmission work is always in good condition.

As a power transmission component broken by the hammer, if there is a problem with the transmission device, it will affect the entire production process. Do the above 3 points and eliminate the hidden troubles in time to ensure the efficient operation of the crushing work.
