Non-standard four-point-contact mounted insert bearing

Abstract

An embodiment of the invention discloses a non-standard four-point-contact mounted insert bearing, comprising a bearing block and a four-point-contact ball bearing. The bearing block is provided witha bearing mounting hole; the inner surface of the bearing mounting hole is an internal spherical surface. The four-point-contact ball bearing that is a non-standard four-point-contact insert bearing at least includes an outer ring, an inner ring, and a steel ball arranged between the outer ring and the inner ring; a line of contacts of the steel ball with circular grooves of the inner and outer rings forms first contact angle a1 and second contact angle a2 with a radial plane of the bearing; the outer surface of the outer ring is an external spherical surface; the external spherical surface ofthe outer ring fits the internal spherical surface of the bearing mounting hole of the bearing block. The non-standard four-point-contact mounted insert bearing can bear radial load or axial load orbear radial and axial joint load, has higher load-bearing capacity, can bear higher tilting torque, can be automatically aligned and corrected through the external spherical surface of the outer ringand the internal spherical surface of the bearing mounting hole even when bearing tilting torque.

Description

Technical field: [0001] The invention relates to a bearing with a seat, in particular to a non-standard four-point contact outer spherical ball bearing with a seat. Background technique: [0002] Bearings with housings are bearing units that combine rolling bearings and housings. They are widely used because of their convenient installation and use, small footprint and low maintenance costs. The existing four-point contact ball bearing with seat generally includes a bearing housing body, an outer ring, an inner ring, several steel balls and a cage arranged between the inner and outer rings. In practical applications, if the inclination of the installation shaft is too large or there is long-axis deflection or bending, a large axial force or overturning moment will be generated, because the self-alignment cannot be realized, which will lead to rapid damage to the bearing. Invention content: [0003] In order to overcome the problem that the existing four-point contact ball...
