Deep groove ball bearings are mainly subjected to radial loads, Mounting structure and can withstand both radial and axial loads. When it only bears radial load, the contact angle is zero. When deep groove ball bearings have a large radial clearance, with angular contact bearing performance, can withstand a larger axial load, deep groove ball bearing friction coefficient is very small, Mounting structure the limit speed is also very high.
Deep groove ball bearings are the most representative of rolling bearings, widely used. Suitable for high speed or even very high speed operation, and very durable, without regular maintenance. The friction coefficient of this kind of bearing is small, the limit speed is high, Mounting structure the structure is simple, the manufacturing cost is low, and it is easy to achieve high manufacturing precision.
The size range and form variety, applied in the precision instrument, low-noise motor, automobile, motorcycle and general machinery industry, is the most widely used in the mechanical industry of a kind of bearings. The main bearing radial load, can also withstand a certain amount of axial load.
After the deep groove ball bearing is mounted on the shaft, the axial displacement of the shaft or shell can be restricted in two directions in the axial direction of the bearing, Mounting structure so the axial orientation can be made in two directions. In addition, this kind of bearing also has certain adjustment ability, when relative to the shell hole inclined 2′~10′, still can work normally, but has certain influence to the bearing life. Deep groove ball bearing cages for steel plate stamping wave-shaped cage, Mounting structure large-scale bearings are used in the car metal solid cage.
Deep groove ball bearings are the most commonly used rolling bearings. Its structure is simple and easy to use. Mainly used to withstand radial load, but when increasing the radial clearance of bearings, with a certain angular contact ball bearing performance, Mounting structure can withstand the diameter, axial joint load.
When the rotational speed is high and the thrust ball bearing is not suitable, it can also be used to withstand the pure axial load. Compared with other types of bearings with the same size as the deep groove ball bearings, Mounting structure the friction coefficient of this kind of bearing is small and the limit speed is high. But not withstanding the impact, not suitable for heavy load.
Pressure into the match: bearing inner ring and shaft to make tight, the outer ring and bearing seat hole is more loose, can be used presses the bearing first pressure on the shaft, the shaft is then loaded into the housing hole together with the bearing, and the assembly sleeve (copper or soft steel) is made on the inner ring end of the bearing, and the outer ring of the bearing is tightly matched with the bearing seat hole. When the inner ring and the shaft are loosely matched, the bearing can be pressed into the housing hole first, Mounting structure then the outer diameter of the assembly sleeve should be slightly smaller than the diameter of the seat hole.
Before installation, the installation personnel are required to be familiar with all the rods, types, sizes and positions in the drawing. If the rod in the transport, Mounting structure stacking and hoisting process caused by deformation must be corrected.
