Angular contact ball bearings mainly bear large unidirectional axial load. Bearing Grease The larger the contact angle is, the greater the load bearing capacity is.
Cage materials include steel plate, brass or engineering plastics, and the forming methods include stamping or turning, which can be selected according to the bearing form or service conditions. Others include combined angular contact ball bearings, double row angular contact ball bearings and four point contact ball bearings.
Angular contact ball bearings can bear both radial and axial loads. It can work at high speed. The larger the contact angle, the higher the axial Bearing Grease bearing capacity. High precision and high-speed bearings usually have a contact angle of 15 degrees. Under the action of axial force, the contact angle will increase.
Single row angular contact ball bearings can only bear axial load in one direction, which will cause Bearing Grease additional axial force when bearing radial load. And can only limit the axial displacement of the shaft or housing in one direction.
If it is installed in pairs, make the outer rings of a pair of bearings opposite, that is, the wide end face to the wide end face, and the narrow end face to the narrow end face. In this Bearing Grease way, additional axial force can be avoided, and the shaft or housing can be limited to the axial clearance in both directions.
Because the raceways of the inner and outer rings of angular contact ball bearings can have relative Bearing Grease displacement on the horizontal axis, they can bear both radial load and axial load – combined load (single row angular contact ball bearings can only bear axial load in one direction, so they are usually installed in pairs).
Cage materials include brass, synthetic resin, etc., which are Bearing Grease distinguished according to bearing form and service conditions.
The technique of selecting grease for angular contact ball bearing. Grease Bearing Grease is a stable solid or semi-solid product composed of dispersing thickener in liquid lubricant, in which additives and fillers aimed at improving some characteristics of grease can be added.
The grease can be attached to the vertical surface without loss at room temperature, and can work in open or poorly sealed friction parts. It has a holding point that can not be replaced by other lubricants. Therefore, grease is used as lubricating material in many parts of automobile and construction machinery and angular contact ball bearing parts.
special lithium based compounds as thickener and various additives such as anti-oxidation, anti-corrosion and Bearing Grease anti-corrosion. Specially developed and designed for sealed bearings, it is characterized by long service life in high temperature environment.
It is widely used in sealed ball bearings requiring low noise, long life or lifetime lubrication, such as rolling bearings in high-speed and high-temperature motors, textile machinery, electric tools, household appliances and office equipment; Clutch bearing, cooling water pump bearing.
The grease used in angular contact ball bearing must have anti rust effect, and the anti rust agent can not be dissolved in water. The grease shall have good adhesion and can form an oil film on the steel surface, which can be maintained even if the grease is filled with water.
Deep groove ball bearing is a widely used rolling bearing. It is characterized by low friction resistance and high speed. It can be used for parts bearing radial load or combined load of radial and axial at the same time.
It can also be used for parts bearing axial load, such as small power motor, automobile and tractor gearbox, machine tool gearbox, general machines, tools, etc. Deep groove ball bearings mainly bear radial load, and can also bear radial load and axial load at the same time. When it only bears radial load, the contact angle is zero.
When the deep groove ball bearing has large radial clearance, it has the performance of angular contact bearing and can bear large axial load. The friction coefficient of deep groove ball bearing is very small and the limit speed is also very high. Bearing characteristics, deep groove ball bearing is a more commonly used rolling bearing.
The utility model has the advantages of simple structure and convenient use. It is mainly used to bear radial load, but when the radial clearance of the bearing is increased,
it has certain performance of angular contact ball bearing and can bear combined radial and axial load. When the rotating speed is high and the thrust ball bearing is not suitable, it can also be used to bear pure axial load.
Compared with other types of bearings with the same specification and size of deep groove ball bearing, this kind of bearing has small friction coefficient and high limit speed. However, it is not resistant to impact and is not suitable to bear heavy load.
After the deep groove ball bearing is installed on the shaft, the axial displacement in both directions of the shaft or housing can be limited within the axial clearance of the bearing, so it can be positioned axially in both directions.
In addition, this kind of bearing also has the ability of centering. When it is inclined by 2 ′～ 10 ′ relative to the shell hole, it can still work normally, but it has an impact on the service life of the bearing.
