Embodiment 1

[0034] refer to Figure 1-2 , the mechanical overload protection device of the present invention includes: a first rotating part 1, a second rotating part 2 and an overload protection assembly; the second rotating part 2 is coaxially arranged inside the first rotating part 1; the overload protection assembly includes a wave track 31 , at least one elastic support part and rolling elements 33 equal in number to the elastic support part; the wave track 31 is arranged on the inside of the first rotating part 1, and the elastic support part is arranged on the outside of the second rotating part 2; the wave track 31 has a closed wave profile Surface, the corrugated profile surface includes crest surface 311 and trough surface 312 connected in sequence; the elastic support part has a groove that can be deformed along the direction away from the wave track 31; Between the grooves, the rolling body 33 is suitable for rotating around its own rotation axis 331 in the groove, and the rol...

Embodiment 2

[0046] refer to Figure 7-8 , the difference between this embodiment and the first implementation is:

[0047] The wave track 31 is arranged on the outside of the second rotating member 2 , and the elastic supporting part is arranged on the inner side of the first rotating member 1 . Specifically, the wave track 31 is arranged outside the second rotating member 2, and the wave track 31 and the second rotating member 2 are integrally formed or the wave track 31 is combined with the second rotating member 2; the elastic support part is arranged on the first rotating member 1 The inner side, and the elastic support part is integrally formed with the first rotating part 1 or the elastic supporting part is combined with the first rotating part 1

[0048] Similarly, in this embodiment, the second rotating member 2 can also be used as the driving member, and the first rotating member 1 can be used as the driven member; or the first rotating member 1 can be used as the driving member...

Abstract

The invention discloses a mechanical overload protection device. The mechanical overload protection device comprises a first rotating piece, a second rotating piece and an overload protection assembly, wherein the overload protection assembly comprises a waveform track, at least one elastic supporting part and a rolling body; the waveform track is arranged on the inner side of the first rotating piece; the elastic supporting part is arranged on the outer side of the second rotating piece, or the waveform track is arranged on the outer side of the second rotating piece; the elastic supporting part is arranged on the inner side of the first rotating piece; the waveform track has a closed waveform contour surface; the waveform contour surface comprises a wave crest surface and a wave trough surface; the elastic supporting part is provided with a groove; the rolling body is a revolving body; the rolling body is contained between the wave trough surface and the groove; the rolling body is suitable for rotating around the rotation axis of the rolling body in the groove; and the rolling body is suitable for rolling relative to the waveform contour surface. According to the mechanical overload protection device disclosed by the invention, under the condition that one rotating piece is overloaded or stuck, the two rotating pieces can rotate relatively to achieve overload protection.

Description

technical field [0001] The invention relates to the technical field of mechanical transmission, in particular to a mechanical overload protection device. Background technique [0002] In the field of mechanical transmission, the transmission of torque between two rotating parts is very common. However, due to the influence of the working environment, it is inevitable that one of the rotating parts will be overloaded or stuck. When such a situation occurs, it will cause damage to the power output mechanism. For example, when the power output mechanism is a motor, the motor It may be burned, which will delay production, delay the construction period, and cause economic losses. Contents of the invention [0003] In order to overcome the disadvantages of the prior art, the object of the present invention is to provide a mechanical overload protection device. When one of the rotating parts is overloaded or stuck, the two rotating parts can rotate relative to each other to real...
