Cylindrical roller bearing capable of bearing bidirectional axial force

Abstract

The invention discloses a cylindrical roller bearing capable of bearing a bidirectional axial force. The cylindrical roller bearing comprises a cylindrical roller bearing inner ring, a cylindrical roller and a cylindrical roller bearing outer ring; stopping edges for preventing the cylindrical roller from axially moving are respectively arranged on the outer cylindrical surface of the cylindrical roller bearing inner ring and the inner cylindrical surface of the cylindrical roller bearing outer ring; the cylindrical roller bearing outer ring is connected and combined through internal threads and external threads by two rings along the axial direction to form a whole; and two stopping edges are respectively arranged on the two rings. The cylindrical roller bearing outer ring is formed by combining two parts with the stopping edges and double stopping edges are arranged on the cylindrical roller bearing inner ring, so that the bearing can bear the bidirectional axial force and the bearing force is greater; the cylindrical roller bearing capable of bearing the bidirectional axial force is formed by being improved on the basis of the traditional cylindrical roller bearing and is combined in a threaded connection mode; the cylindrical roller bearing has a simple structure and is easy to manufacture; the nominal contact angle of the cylindrical roller bearing is 0 degree; the roller is linearly contacted with the rollways and has strong bearing capacity; and during rotating, the influence of the centrifugal force on the cylindrical roller bearing is less, so that the limiting speed of work is higher.

Description

technical field

[0001] The invention relates to a cylindrical roller bearing, in particular to a cylindrical roller bearing capable of bearing bidirectional axial force. Background technique

[0002] Cylindrical roller bearings are well known in the prior art. When the shaft rotates, gears and worms on the shaft will generate radial force and axial force on the bearing at the same time, and sometimes this axial force is bidirectional. Since the rollers of cylindrical roller bearings are in line contact with the raceway, they can withstand large radial loads, and sometimes can also withstand large axial loads, and the limit speed is high. The more common bearings on the market that can withstand radial force and bidirectional axial force at the same time include crossed cylindrical roller bearings, tapered roller bearings and angular contact ball bearings, etc., but due to the cross installation of crossed cylindrical roller bearings High cost, difficult manufacturing and lo...
