We should know these characteristics of deep groove ball bearings

wallpapers News 2020-11-20
Deep groove ball bearings are basic parts widely used in various mechanical equipment. Deep groove ball bearings are generally composed of four basic parts: inner ring, outer ring, rolling element and cage (alias "four major parts", most of them There must also be moisturizers in the workplace).
 
The inner ring of deep groove ball bearings is generally assembled on the shaft and rotates with the shaft. The outer ring is generally installed in the seated bearing or in the casing of the mechanical parts to act as a support plate. However, in some applications, the outer ring rotates, the inner ring is fixed or both the inner and outer rings rotate; there are also more diverse components; there are also those without retainers, without inner rings, and without outer rings. Wait for the circle.
 
The ring that cooperates with the shaft is called the shaft ring, and the ring that matches the housing of the bearing or mechanical part is called the seat ring. The rolling surface of the rolling elements on the ring is called the raceway, and the raceway of the ball bearing is also called the raceway. The rolling elements roll between the inner and outer ring raceways. The size and the total number of the rolling elements affect the bearing capacity of the rolling bearing.
Compared with other types of bearings of the same size, deep groove ball bearings have a small friction coefficient, high limit speed and high precision. They are the preferred bearing type for users when selecting models. Deep groove ball bearings are simple in structure and easy to use. They have the largest production batch and the widest application range.
 
Deep groove ball bearings are mainly used to bear radial load, but also can bear certain axial load. When the radial clearance of the bearing increases, it has the properties of an angular contact ball bearing and can withstand alternating axial loads in two directions. Structurally, each ring of a deep groove ball bearing has a continuous groove raceway with a cross-section of approximately one-third of the equatorial circumference of the ball.
 
Deep groove ball bearings include the metric system, inch system, customized series, open type, metal sealed type, rubber sealed type and other different types.
For assembled deep groove ball bearings, the internal state cannot be observed from the outside. In addition, the vibration and noise performance of deep groove ball bearings must be checked under actual rotating conditions.
