Because the rolling body in the thrust taper roller bearing is a cone roller, the rolling bus and the raceway bus of the washer meet at a certain point on the axis line of the bearing. So the rolling surface can form pure rolling, and the ultimate speed is higher than that of the thrust cylinder roller bearing.
The thrust cone roller bearing can withstand a unidirectional axial load.
The type of thrust cone roller bearing has a name is the 90000 type.
Due to the low production volume of thrust cone roller bearings, factories produce many non-standard external dimension models, while the series of standard external dimensions and varieties are less produced. So there is no national standard on external dimensions of such bearings at present.
The double row taper roller bearing structure is various. The largest number is 35000 type, there are a double raceway outer ring and two inner rings. There is a separate ring between the two inner rings, changing the thickness of the packer ring can adjust the clearance. This bearing can bear bidirectional axial load while bearing radial load and limit axial displacement of shaft and shell within the range of bearing axial clearance.
The type code of taper roller bearing is 30000, and taper roller bearing is separated type bearing. In general, especially in GB/ t307. 1-94 "rolling bearing centripetal bearing tolerance". The outer ring and inner assembly of taper roller bearing within the range of dimensions involved are 100 percent interchangeable. The outer ring angle and the outer raceway diameter have the same standard as the external dimension. It doesn't allow changes at design time. So that the outer ring and inner components of tapered roller bearings are interchangeable throughout the world.
The main function of the taper roller bearing is to bear combined radial and axial loads, mainly radial loads. Compared with angular contact ball bearing, the bearing capacity is large and the ultimate speed is low. Tapered roller bearings are capable of bearing axial loads in one direction and limiting axial displacement in one direction of the shaft or housing.
Each deep groove ball bearing sleeve has a continuous groove raceway with a cross-section of approximately. And its one-third of the length of the equatorial circumference of the ball.
The deep groove ball bearing the main function is to bear radial load but also can bear certain axial load.
When the bearing radial clearance increases, it has the property of angular contact ball bearing and can bear the axial load of two directions alternating.
Compared with other types of bearing of the same size, this kind of bearing has a small friction coefficient, high limit speed, and precision. It is the preferred type of bearing when selecting the type by users.
Deep groove ball bearing structure is simple, easy to use, is the largest production volume, the most extensive application of bearings.
