6. Thrust ball bearing assembly
There are two key points in the assembly of thrust ball bearings. One is the control of the pressing quality of the cage and the steel ball, and the other is the control of the nominal height T after the bearing is assembled. In addition, since the shaft ring and the seat ring can be separated, it brings a management problem. It is to prevent the mixing of imported bearing parts. The M-type stamping cage uses a flanged assembly die. After pressing, the steel ball is required to rotate flexibly in the pocket, but it cannot fall off from the pocket, and the technical regulations check the amount of movement of the steel ball in the pocket. If the solid cage is imprinted too deeply, the movement of the steel ball will be small, and the connection between the embossed convex part and the cage is too small and the strength is insufficient, which is prone to the phenomenon of falling blocks, causing the cage to be scrapped. There is little difference between the inner diameter of the small thrust ball bearing seat washer and the shaft washer, and there is no obvious difference between the two sets. In order to prevent the phenomenon of mixed sets, it is found that two sets of bearings are both seat washers or shaft washers in the assembled set of bearings. This requires certain measures. Usually, the drawing ring and the seat group are distinguished by auxiliary tooling when the sleeve is assembled, or the inner diameter size is checked with an inner diameter plug gauge before sampling the nominal height. For the convenience of checking the inner diameter, put the seat ring on the bottom and the shaft ring on the top. If the inner diameter of the seat ring has obvious quenching heating oxidation color or has not been ground, it is not necessary to check the inner diameter size, and the difference between the shaft washer and the seat ring can be clearly seen, and it is not easy to mix. After the thrust ball bearing is assembled, the nominal height T needs to be measured to confirm whether it is qualified. When measuring, calibrate with a height block or standard part, and measure the load, the bearing needs to be rotated dozens of times, and the minimum height must be reached.
When the thrust ball bearing operates at high speed, the contact angle between the steel ball and the radial plane of the raceway will be affected by centrifugal force, which will cause the sliding of the steel ball relative to the raceway. Adhesive wear from this sliding can damage the bearing. To prevent this damage, the minimum load on the thrust ball bearing must be guaranteed, see Equation 1 or Equation 2, whichever is the larger of the calculated values.
Formula 1: Famin=K・n*n
Formula 2: Famin=Coa/1000
Famin: Minimum axial load (N)
You will find that these thrust ball bearings will last much longer than other types of bearings because they were made with quality materials and craftsmanship in mind.They will be able to handle any type of pressure or temperature level without failing you during your next project at home or the workplace.
Top Quality and High Precision Thrust Ball Bearing
Thrust ball bearings are used to support radial load and transmit it to a rotating shaft or housing.The concept of operation is based on the rolling contact between a spherical outer ring and a cylindrical inner ring made of steel,hardened carbon steelor stainless steel.It is
characterized by a high radial load carrying capacity,good mechanical performance,and low noise level.It has many applications in industry including aviation,energy,machinery manufacturing,metallurgy, mining industry,and more.
Thrust ball bearings are designed and manufactured to provide high
precision,high load capacity,and long life.They are available for a wide range of applications including the automotive industry,the aerospace industry, machine tools,pumpsand compressors.
The thrust ball bearing has two rows of balls and one or more inner and outer rings. The inner ring is normally made from bronze and the outer ring is from steel.The cage is made from brass or stainless steel.The balls are made of chrome steel or stainless steel.
The balls are supported by a cage that prevents them from coming into contact with each other as they rotate in their sockets.The ball bearings are used in pairs or groups in order to transmit loads in both directions- axially(thrust) and radially(thrust).
The basic thrust bearing consists of an inner ring in rolling contact with its outer race(roller cage assembly),which is made up of a number of rollers held together by cage clips.
Thrust ball bearings have been used for many years to provide high- quality,low-friction motion for many different types of machines and devices. These bearings have become increasingly popular due to their precision and durability.
