Bearing capable of bearing axial force

Abstract

The invention relates to a bearing capable of bearing axial force with a flange edge, comprising an outer ring, an inner ring, a roll ball, a retainer and seal rings, wherein the retainer is arranged outside the roll ball; dustproof grooves are arranged at the inner walls of the left end and the right end of the outer ring; the seal rings are arranged in the dustproof grooves; the outer walls of the seal rings and the outer wall of the inner ring adopt contact seal; the length of the inner ring is greater than the length of the outer ring; the two end parts of the inner ring are respectively extended out from the corresponding two end parts of the outer ring; the flange edge which protrudes in the radial direction is arranged at the circumference of the outer wall of the right end part of the outer ring; the right end face of the flange edge and the right end face of the outer ring are arranged parallelly and levelly; and the included angle of the connection line of the intersection point of the plane of the right end face of the outer ring and the axis of the inner ring and the spherical centre of the roll ball as well as the perpendicular line of the axis from the spherical centre of the roll ball to the inner ring is 20-30 DEG. The bearing capable of bearing the axial force, provided by the invention, can replace a full ball bearing to be used for the decoration of housings and has the advantages of long service life, lower subsequent maintenance cost and the like.

Description

technical field [0001] The invention relates to a bearing, in particular to a bearing with a flange side for bearing axial force. Background technique [0002] At present, bearings used for residential decoration are more and more widely used. For example, sliding sleeves are generally used for the moving parts of doors and windows, and there are also simple full-ball bearings. The biggest disadvantage is that the service life is short and the subsequent maintenance costs are high. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art, and provide a bearing that can replace full-ball bearings for residential decoration, has a long service life, and can bear axial force with a flange. [0004] According to the technical solution provided by the present invention, the bearing includes an outer ring, an inner ring, balls, a cage and a sealing ring. There is an outer raceway, and the combination of the inner r...
