Thrust Spherical Plain Bearings

● Introduction

Thrust spherical plain bearing has a simple structure, consisting of an outer ring and an inner ring. It is a spherical plain bearing. The shaft washer and seat washer of the bearing are all hardened bearing steel, and the seat ring has oil grooves and oil holes. Bearings can bear axial load in one direction, or combined radial and axial load. When subjected to combined load, its radial load value shall not be greater than 0.5 times the axial load value. The axial load capacity increases with the increase of the contact angle. When the contact angle is equal to 90⁰, it can bear pure axial load, the seat washer and the shaft washer can be separated, and the lubrication performance is excellent. Similar to the radial spherical plain bearings, the thrust spherical plain bearing adopts special processing methods, such as surface phosphating, zinc plating, chrome plating or outer sliding surface lining, padding, spraying, etc. It is anti-corrosion, wear-resistant, self-aligning, well lubricated, self-lubricating without pollution.

Spherical plain thrust bearings are widely used in forging machine tools, construction machinery, hydraulic equipment, automation equipment, automobiles, water conservancy machinery and other industries.

● Bearing Series

The type of the bearing is GX series.

● Production Details

◆ Selection of grinding wheels for grinding bearing rings

The grinding wheel affects the grinding effect in many ways, including machining accuracy, surface quality and production efficiency. In order to obtain a good grinding effect, the grinding wheel must be correctly selected according to the physical and mechanical properties of the workpiece material, the heat treatment method, the machining accuracy and surface roughness requirements, the size of the grinding allowance, the shape and size of the workpiece, and the grinding method. The five factors that determine the properties of the grinding wheel are abrasive, particle size, binder, hardness and organization, which are often selected according to the following principles in production.

◆ Cleanliness of bearings

Before assembling the ring, it should be carefully cleaned, which is vital to reduce the vibration and noise of the bearing. Cleaning is to remove dirt such as oil and iron filings on the ferrule. It should be demagnetized before cleaning to improve the cleanliness of the bearing, purify the working environment of assembly and packaging, and avoid artificial contamination of bearing parts and secondary pollution when the finished product is exposed. Generally, the cleaned bearing can reduce the noise by 3dB compared with the uncleaned bearing, and can eliminate the defects such as bumps, scratches, jams, pits and rust on the surface.

● Annealing of Bearing Steel

There are several types of annealing of bearing steel, such as diffusion annealing, stress relief annealing and spheroidizing annealing. The annealing of bearing ring forgings should be spheroidized annealing. Spheroidizing annealing changes the structure into fine-grained pearlite with uniform distribution, which provides the best original structure for quenching. improves plasticity, reduces hardness, and facilitates subsequent cutting.

The GCr15 steel ferrule blank is heated to a temperature slightly above the critical point (the temperature at which pearlite transforms into austenite when heated). Stay at this temperature for a period of time, and then cool down at a certain speed to obtain a uniformly distributed, fine, spherical pearlite structure. This process is called annealing. Heating temperature, holding time and cooling rate are the three elements of the annealing process.
