Novel harmonic bearing

Abstract

The invention relates to a novel harmonic bearing. The novel harmonic bearing comprises a flexible tooth outer ring, a rolling body, a wave generating inner ring and a holder; the flexible tooth outerring is designed into the standard flexible tooth outer ring with a standard thin-wall bearing and a standard harmonic speed reducer as supporting, and can also be customized to meet the special requirements of a user; the flexible tooth outer ring is provided with bearing face teeth which are used for being connected with fixed steel wheel inner teeth used in cooperation with the bearing face teeth; the rolling body corresponds to the standard thin-wall bearing; and the wave generating inner ring is oval, and with the standard thin-wall bearing and the standard harmonic speed reducer as supporting, a roller bed, a long shaft and a short shaft are designed, and the long shaft and the short shaft are different in length. The novel harmonic bearing has the beneficial effects that the transmission efficiency of the product can be improved, transmission chains are reduced, the transmission precision is improved, the volume is small, the weight is small, the structure is simple, consumption is reduced, and energy is saved, the transmission capacity of the bearing face teeth is achieved, and therefore the defects that an existing harmonic generator (containing the tooth difference) typespeed reducer is complicated in structure, high in cost, large in manufacturing difficulty, not high in efficiency and the like are overcome.

Description

technical field [0001] The invention relates to the field of speed changers, in particular to a novel harmonic bearing. Background technique [0002] Bearings are an important part of contemporary mechanical equipment and are widely used. The bearing is composed of four parts: inner ring, outer ring, rolling element and cage. Its main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotation accuracy, and the transmission of force is relatively rare. However, the present invention makes the bearing no longer limited to reducing the friction coefficient, ensuring the rotation accuracy, and can also be used as a precision component for transmitting force in the mechanical part. [0003] With the gradual acceleration of China's smart manufacturing 2025, the demand for precision reducers is also heating up. For example: Harmonic, cycloidal, and frictional reducers are all driven by a wave generator to gen...

[0006] The existing Chinese patent document CN 102820104A discloses a mechanical device that realizes the application of a harmonic reducer to two-way transmission. Teaching a Self-Teaching Robot's Driveline

When the mechanical system does reverse transmission, the larger transmission ratio of the reducer will make the robot encounter too much resistance when manually guiding the robot to move, resulting in difficulty in dragging
