Advantages of deep groove ball bearing: small friction resistance, high speed, deep groove ball bearing is one of the most widely used bearings, can be used to bear radial load or radial and axial simultaneous action of the combined load on the machine, but also can be used to bear axial load on the machine.
Deep groove ball bearing structure is simple, compared with other types of easy to achieve high manufacturing accuracy, the use of extremely common. Select a larger radial clearance when the axial load carrying capacity increases, bearing pure radial force contact angle is zero. When there is an axial force, the contact angle is greater than zero.
Generally use the stamping wave-shaped cage, turning solid cage, sometimes also use nylon frame.
Deep groove ball bearings in addition to the basic type, there are various variants of structure, such as: deep groove ball bearings with dust cover; deep groove ball bearings with rubber seal; deep groove ball bearings with stop groove; deep groove ball bearings with ball loading gap of large load capacity; double row deep groove ball bearings.
1, in the structure of deep groove ball bearings each ring has a cross-section of about one-third of the circumference of the ball continuous groove type raceway. It is mainly used to bear radial load, but also can bear a certain axial load.
2, in the bearing radial clearance increases, has the nature of angular contact ball bearing, can withstand two directions of alternating axial load;.
3, small friction, high speed.
4, simple structure, low manufacturing cost, easy to achieve high manufacturing accuracy.
5, the general use of stamping wave-shaped cage, inner diameter greater than 200mm or high-speed operation of the bearing, using the solid cage of the car.
Deep groove ball bearing is the most representative rolling bearing, widely used. Suitable for high speed or even very high speed operation, and very durable, low maintenance costs, long operating cycle. However, they require regular inspection and maintenance by professional technicians to ensure the safety and reliability of operation and to improve the cycle time and quality of operation.
The assembly of deep groove ball bearings requires high professional skills of assemblers and strict implementation of technical requirements and operating procedures in the assembly process.
The accuracy, life and performance of the bearing will be affected by the good or bad bearing mounting. Therefore, it is necessary to install the bearings according to the requirements.
1、Clean the bearing and related parts
2, check the size of the relevant parts and finishing.
3, the installation method bearing installation should be based on the bearing structure, size and bearing parts with the nature of the pressure should be added directly in the tight fit to the ring end face, not through the rolling body to transfer pressure.
