Thin-wall normal-section robot bearing

Abstract

The thin-wall normal-section robot bearing comprises an inner ring and an outer ring which are coaxially arranged in a sleeved mode, the outer wall of the inner ring and the inner wall of the outer ring are each provided with a roller path used for rolling of a ball, each roller path comprises a radial perpendicular bisector, and a contact part making contact with the ball is arranged between each roller path and the ball. The contact parts are symmetrically arranged on the two sides of the perpendicular bisector, the included angle between the normal of each contact part and the perpendicular bisector is a contact angle, and the contact angle is larger than 30 degrees. The outer wall of the inner ring and the inner wall of the outer ring are respectively provided with the raceways for rolling of the balls, the contact parts of the raceways and the balls are symmetrically arranged on the two sides of the perpendicular bisector, and the contact angle is set to be larger than 30 degrees, so that the bearing capacity of the axial overturning moment of the bearing can be improved.

Description

Technical field [0001] The present invention relates to the technical field of bearing design, in particular to a thin-walled positive section robot bearing. Background [0002] The demand for industrial robots market is developing faster and faster, and the demand for robots from the service field is also increasing, under this trend, the demand for corresponding bearings of industrial robots is also in urgent need of research and development. In the field of robot joints, as one of the most critical components of industrial robots, thin-walled positive-section robot bearings have a wide range of applications. Thin-walled positive section robot bearing, is one of the key accessories of industrial robots; industrial robots require high working accuracy, strong consistency in continuous production, small mutual error and other special requirements, these items are reflected in the robot reducer all by the bearing to complete, to meet the above requirements to design robot bearings...

AI Technical Summary

Problems solved by technology

The key point of this solution is to use the sealing ring to achieve a better sealing effect. The structure of the bearing itself has not been greatly improved, and compared with the existing bearings, the bearing capacity of the axial overturning moment has not been improved.
