Structure and performance characteristics of thrust taper roller bearing:
As the rolling body in the thrust tapered roller bearing is tapered roller, the rolling surface can form pure rolling and the limit speed is higher than that of the thrust cylindrical roller bearing, because the rolling busbar and the raceway busbar of the washer meet at a certain point on the axis line of the bearing.
Thrust tapered roller bearings can withstand unidirectional axial load.
The type of thrust taper roller bearing is type 90000.
Because the output of thrust taper roller bearing is less, the models that have been produced by various factories are mostly non-standard external dimensions, and the series of standard external dimensions are less produced. Therefore, there is no national standard for external dimensions of such bearings.
Structure and performance characteristics of thrust angular contact ball bearing:
Thrust angular contact ball bearing contact Angle 60 ° commonly used thrust angular contact ball bearings are generally two-way thrust angular contact ball bearings, mainly used for precision machine tool spindle, commonly used together with the double row cylindrical roller bearing, it can be subject to bi-directional load and have high precision, good rigidity, low temperature, high speed, convenient installation.
Structure and performance characteristics of double-row tapered roller bearings:
Double row tapered roller bearings have various structures, the largest of which is type 35,000. There is a double raceway outer ring and two inner rings. There is a gap between the two inner rings.This kind of bearing can bear bidirectional axial load while bearing radial load, and can limit the axial displacement of shaft and housing within the range of axial clearance of bearing.
Structural features of tapered roller bearings:
Tapered roller bearing type code for 30000, tapered roller bearing for separation bearings.In general, especially in GB/ t307.1-94 "radial bearing tolerance of rolling bearings", tapered roller bearings within the size range involved are 100 percent interchangeable between the outer ring and the inner components.The Angle of the outer ring and the diameter of the outer raceway have been standardized with the external dimensions.It is not allowed to be changed during design and manufacture.As a result, the outer ring of tapered roller bearings and the inner components can be interchangeable throughout the world.
Tapered roller bearings are mainly used to bear combined radial and axial loads, mainly radial loads.Compared with angular contact ball bearings, the bearing capacity is large, the limit speed is low.Tapered roller bearings can withstand axial load in one direction and limit axial displacement of the shaft or housing in one direction.
Features of deep groove ball bearing:
Structurally, each ring of a deep groove ball bearing has a continuous groove raceway whose cross section is approximately one third of the length of the ball's equatorial circumference.
Deep groove ball bearing is mainly used to bear radial load, but also can bear a certain axial load.
When the radial clearance of the bearing increases, it has the property of angular contact ball bearing and can bear the axial load alternating in two directions.
Compared with other types of bearings of the same size, the friction coefficient of this type of bearings is small, the limit speed is high, and the accuracy is high.
The deep groove ball bearing is simple in structure and easy to use.
