Five types of bearing structure, performance features
Thrust tapered roller bearing structure, performance features? Due to thrust tapered roller bearings for tapered roller, roller of the structure due to rolling busbar and washer raceway on the bus are concurrent in the bearing of a point on the axis line, thus can form pure rolling, rolling surface limit rotational speed is higher than the thrust cylindrical roller bearing. Thrust tapered roller bearings can withstand the one-way axial load. Thrust tapered roller bearing type code 90000 type. Due to low production of thrust tapered roller bearing, GeChang has production model for non standard size, shape and standard appearance size series, varieties of production is less, so there is no dimension of this bearing the national standard.
Angular contact thrust ball bearing structure, performance features? 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.
The structure and characteristics of double row circular cone roller bearings? Double row tapered roller bearing structure is various, the most is a lot of type 35000, has a double raceway outer ring and two inner ring, a baffle between the two inner ring, changing the thickness of the baffle can adjust the clearance. This type of bearings in bear radial load at the same time it can be subject to bi-directional load, can be within the scope of the bearing axial clearance limit shaft and the shell axial displacement.
The structure characteristics of tapered roller bearing? Tapered roller bearing type code 30000, tapered roller bearing for separating type bearing. In general, especially in the GB/T307.1-94 "rolling bearing centripetal bearing tolerance" involved in within the scope of the size of the tapered roller bearing outer ring and inner components is gm's one hundred percent can be used interchangeably. The Angle of the outer ring and the outer raceway diameter size has the same size and appearance has standardized rules. Do not allow the changes in the design and manufacture. As to make the taper roller bearing outer ring and inner components are interchangeable common throughout the world. Tapered roller bearing is mainly used to bear the joint mainly consisting of radial load and axial load. Compared with the angular contact ball bearing, large carrying capacity, limit rotational speed is low. Tapered roller bearings can withstand axial load in one direction, can limit axial displacement of shaft or housing in one direction.
The characteristics of deep groove ball bearing? Deep groove ball bearing in the structure of each ring has cross section is about the equator of the ball perimeter of a third consecutive raceway groove type. Deep groove ball bearing is mainly used to bear radial load, also can absorb a certain amount of axial load. When bearing radial clearance increases, has the properties of Angle contact ball bearing, can carry alternating axial load in two direction. Compared with other kinds of bearings of the same size, such bearing small friction coefficient, extreme high speed, high precision, is a user selection of the preferred type of bearing. Deep groove ball bearing has simple structure, easy to use, is the production batch is the largest, the most widely application scope of a class of bearings.
