What is a deep groove ball bearing
Deep groove ball bearings (GB/T 276—2003) originally listed radial ball bearings are the most widely used rolling bearing. It is characterized by low frictional resistance and high speed. It can be used on parts that bear radial load or a combined load that acts on both radial and axial directions. It can also be used on parts that bear axial load, such as low-power motors, Automobile and tractor gearboxes, machine tool gearboxes, general machines, tools, etc.
Deep groove ball bearings are the most common type of rolling bearings.
The basic deep groove ball bearing consists of an outer ring, an inner ring, a set of steel balls, and a set of cages. There are two types of deep groove ball bearings, single row, and double row. The deep groove ball structure is divided into two types: sealed and open. The open type means that the bearing does not have a sealed structure. The sealed deep groove ball is divided into dust-proof and oil-proof. seal. The dust-proof seal cover material is stamped with a steel plate, which only serves to prevent dust from entering the bearing raceway. The oil-proof type is a contact oil seal, which can effectively prevent the grease in the bearing from overflowing.
The single row deep groove ball bearing type code is 6, and the double row deep groove ball bearing type code is 4. Its simple structure and convenient use make it the most commonly produced and widely used type of bearing.
The working principle of deep groove ball bearings
Deep groove ball bearings mainly bear radial load, but 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 a large radial clearance, it has the performance of an angular contact bearing and can bear a large axial load. The friction coefficient of the deep groove ball bearing is very small and the limit speed is also high.
Bearing characteristics of deep groove ball bearings
Deep groove ball bearings are the most commonly used rolling bearings. Its structure is simple and easy to use. It is mainly used to bear radial load, but when the radial clearance of the bearing is increased, it has a certain performance of angular contact ball bearing and can bear the combined radial and axial load. When the speed is high and 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 specifications and dimensions of deep groove ball bearings, this type of bearing has a small friction coefficient and a high limit speed. But it is not resistant to impact and is not suitable for heavy loads.
After the deep groove ball bearing is installed on the shaft, the axial displacement of the shaft or the housing can be restricted within the axial clearance of the bearing, so it can be axially positioned in both directions. In addition, this type of bearing also has a certain degree of aligning ability. When it is inclined 2'-10' with respect to the housing hole, it can still work normally, but it will have a certain impact on the life of the bearing.
Deep groove ball bearing processing form
Multi-process processing: Generally, the production of bearings requires 20-40 processes, with more than 70 processes.
Forming processing: The working surfaces of the bearing parts are all rotary forming surfaces, which are suitable for processing by the forming method.
Precision machining: Most of the surface of the bearing parts must be ground, and the grinding dimensions and geometric accuracy are in μm.
Deep groove ball bearing application
Deep groove ball bearings can be used in gearboxes, instrumentation, motors, household appliances, internal combustion engines, transportation vehicles, agricultural machinery, construction machinery, engineering machinery, roller skates, yo-yos, etc.
