Rolling bearing pedestal and rolling bearing pedestal are installed differently

There are two main types of sliding bearing equipment:

One is sectional sliding bearing equipment, and the other is integral sliding bearing equipment.

1. Clean and inspect the bearing bush;

First, check the bearing model, clean the bearing, tap the appearance of the bearing pad with a copper hammer, and inspect the cracks, holes, and sand holes with static hearing.

2. Fix the bearing seat;

Make sure that the center line of the bearing block is on the same shaft. Then check the wire drawing method and painting.

3. Equipment bearing bush

The key points to pay attention to when installing equipment bearing shells are:

The contact surfaces of the upper and lower bearing pads should be tight;

2. The fit between the bearing bush and the bearing seat - generally small transition fit;

The diameter of the bearing bush shall not be too large or too small;

4. The positioning pin equipment should be firm;

5. There should be no axial clearance between the flange or tab and the bearing seat;

No matter how good the bearing pedestal steel is, their use is limited, such as temperature. In the application state of the bearing block, assuming that the mold temperature is too high, the mold core appearance is prone to cracking at the initial stage, and some bearing blocks are subject to large-scale cracking, with the mold number not exceeding 2000. Therefore, due to the excessively high temperature of the bearing block, the mold core changes color when the bearing block is consumed.

Through measurement, it reaches above 400 degrees. At this temperature, the release agent is prone to cracking in severe cold, and the consumed product is prone to deformation, strain, and adhesion. The use of cold water in bearing pedestals can greatly reduce the use of mold release agents, preventing operators from using mold release agents to reduce the temperature of the bearing pedestals.

Its advantages are to improve the service life of bearing seats, save die casting cycles, improve production quality, reduce mold adhesion and strain, and reduce the use of release agents. It can also reduce the loss of the ejector pin and core caused by overheating of the bearing pedestal temperature.
