Meaning of bearing seat, common problems and solutions

The turntable bearing pedestal is a large and oversized bearing pedestal capable of accepting comprehensive loads, characterized by compact structure, sensitive rotation, and convenient device maintenance. Where there are bearings, there must be support points. The inner support point of the bearing is a shaft center, and the outer support is called a bearing seat.

Meaning of bearing seat

Because bearings can choose different types of bearing blocks, and bearing blocks can choose different types of bearings. Bearing blocks are fast, easy, and excellent, and many large foreign bearing companies also have their own bearing block catalogs. However, the same bearing housing model has different markings in different company samples. For different applications of standard bearing blocks, the bearing blocks can be made of different materials such as gray cast iron, ductile iron, cast steel, stainless steel, plastic, and so on.

Common problems and solutions for bearing seats:

1、 Wear issues

Wear is a common problem in bearing seats, and bearing seat wear often occurs.

2、 Repair method

Traditional methods generally use surfacing and machining for repair, but surfacing can cause the surface of the part to reach high temperatures, resulting in deformation or pear shaped patterns of the part, and the size obtained through machining can greatly extend downtime. On the other hand, the on-site repair uses forsythia blue polymer composite material, which has no thermal impact and unlimited repair thickness. The abrasion resistance of the product and the non yielding property of metal materials ensure 100% contact and fit of the repaired parts, reduce the impact vibration of the equipment, and avoid the possibility of wear. On-site repair and avoidance of processing can save enterprises a lot of downtime and create enormous production value.

3、 Partial bearing pedestal repair process

1. Surface treatment: Remove the oil and water from the surface to be repaired/kloc-2.

2. Coordination and maintenance materials

3. Evenly coat the material on the bearing pedestal maintenance site and firmly fill it.

After the material has solidified, the surface can be appropriately heated to accelerate its solidification.

General bearing seat wear can be repaired within 3-6 hours, and can be easily operated without special equipment and training. Compared with "advanced" technologies such as laser welding and cold welding, it saves time and effort, and the cost is only 1/5-1/10 of the general repair cost. Field maintenance reduces equipment maintenance time and transportation costs. Example: This bearing block is the main drive reducer of the coal mill in the boiler workshop of a thermal power plant. The reducer transmits large torque. During long-term operation, there is a gap between the bearing pedestal and the outer ring of the bearing, resulting in uneven wear of the bearing chamber. The main wear part is located on the upper cover of the gearbox, and the lower housing is slightly worn. The deep wear depth is around 2 mm. Using polymer composite technology, the entire repair work can be completed within 4 hours, and the material curing time is 8 hours, ensuring the production of the enterprise. It saves a lot of valuable time and low cost for enterprises.
