The difference between tapered roller bearings and thrust ro
Tapered roller bearings mainly bear radial combined load in diameter and axial direction.Bearing capacity depends on the raceway Angle of the outer ring, the greater the Angle, the greater the bearing capacity.This kind of bearing belongs to separate type bearing, which can be divided into single row, double row and four row tapered roller bearings according to the number of rolling body in the bearing.
Tapered roller bearings have a conical inner ring and an outer ring raceway, with tapered rollers arranged in between.All projection lines on the conical surface meet at the same point on the bearing axis.This design makes tapered roller bearings particularly suitable for bearing combined (radial and axial) loads.The axial load capacity of the bearing is mostly determined by the contact Angle a.The greater the alpha Angle, the higher the axial load capacity.The Angle is expressed by the calculation coefficient e;The larger the e value, the larger the contact Angle, the greater the applicability of bearing bearing axial load.
Tapered roller bearings are usually separable, i.e., a tapered inner ring consisting of an inner ring of the roller and retainer assembly may be mounted separately from the tapered outer ring (outer ring).
Tapered roller bearings are widely used in automobile, rolling mill, mining, metallurgy, plastic machinery and other industries.
Thrust ball bearing composition: Thrust ball bearing is composed of seat ring, shaft ring and steel ball retainer assembly.The bearing ring matched with the shaft and the bearing ring matched with the housing.
Thrust ball bearing type: according to the force, there are unidirectional thrust ball bearing and bidirectional thrust ball bearing.
Unidirectional thrust ball bearing can bear unidirectional axial load.
Bidirectional thrust ball bearing can bear bidirectional axial load.Bidirectional thrust ball bearing with ring and shaft mating.The mounting surface of the seat ring is spherical bearing, which has the performance of centering and can reduce the influence of mounting error.
Thrust ball bearing can not bear radial load, the limit speed is low.
Features: 1. With one-way, two-way type; 2.
2. In order to allow mounting errors, whether one-way or two-way, spherical aligning spherical pedestal type or spherical pedestal type with spherical seat ring type can be selected;
3. High-quality steel -- ultra-clean steel that can extend the bearing life by up to 80%;
4. High grease technology - extends the life of grease and improves the performance of bearings;
5. High-grade steel ball -- quiet and smooth when rotating at high speed;
6. Use the ring in the option to allow mounting errors.
