Deep groove ball bearings (GB/T 276 - 1994), formerly known as single row radial ball bearings, are the most widely used rolling bearings. It is characterized by small friction resistance and high speed, which can be used to withstand the combined load of radial and radial and axial loads. It can also be used in the mechanical parts of the axial load, such as small power motor, automobile and tractor gearbox, machine gear box, general machine, tool and so on.
Deep groove ball bearings are the most common type of rolling bearings.
The basic type deep groove ball bearings are made up of an outer ring, an inner ring, a set of steel balls and a group of retaining structures. There are two types of deep groove ball bearings, single and double row, deep groove ball structure is also divided into two kinds of sealing and opening, the open type is the bearing without sealing structure, sealed type deep groove ball is divided into dust proof seal and oil proof seal. The dust-proof sealing cover material is made of steel sheet and only prevents dust from entering the bearing raceway. The oil proof type is a contact type oil seal, which can effectively prevent the grease from overflow in the bearing.
The single row deep groove ball bearing type code is 6, the double row deep groove ball bearing code is 4. Its structure is simple and easy to use. It is the most widely used and most widely used kind of bearings.
Working principle
Deep groove ball bearings mainly bear radial load, and can also bear radial load and axial load. 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, which can bear large axial load. The friction coefficient of deep groove ball bearing is very small and the ultimate speed is very high.
Bearing characteristics
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 bearing radial clearance is increased, it has the performance of a certain angular contact ball bearing, which can bear the joint load of the diameter and the axial direction. When the speed is high and the thrust ball bearing is not suitable, it can also be used to bear pure axial load. Compared with other bearings of the same size as deep groove ball bearings, this type of bearing has small friction coefficient and high limit speed. But it is not resistant to impact and is not suitable for heavy load.
After the deep groove ball bearing is mounted on the axis, the axial displacement in the two directions of the shaft or shell can be restricted within the axial clearance range of the bearing, so the axial orientation can be made in the direction of the axial direction. In addition, this kind of bearing has a certain ability to adjust the heart. When it is 2 '~ 10' relative to the shell hole, it can still work normally, but it has a certain effect on the bearing life.
Deep groove ball bearings can be used for gearbox, instrument, motor, household electric appliance, internal combustion engine, traffic vehicle, agricultural machinery, construction machinery, engineering machinery, roller type roller skating shoes, leisurely ball and so on.
