Problems solved by technology

However, the structure of the worm gear reducer is heavy, the transmission efficiency is low, the precision is poor, and the input and output are not in the same axis, and the operation stability is poor; the core component of the harmonic reducer is periodically deformed during operation, and it is prone to fatigue damage , and the impact resistance and rigidity of the whole machine are poor, and the input speed is limited; although the planetary reducer has excellent overall performance and can meet the needs of equipment operation, it has very high requirements for the selection of raw materials for components, manufacturing technology and processing accuracy. make the equipment expensive

Embodiment 1

[0052] This embodiment provides a slewing device 1 that can be used as a main part of an intermediate transmission in a multi-stage transmission.

[0053] like figure 2 As shown, the swivel device 1 includes a base body 1c. End-to-end raceways 1c-1 are arranged on the base body 1c. The raceway 1c-1 is used to accommodate several first rollers 1c-2. Preferably, the first rolling element 1c-2 is a rolling part formed by rotation, which can revolve around the axis of the base body 1c on the raceway 1c-1 in a manner of self-rotation on its own axis. For example, the first roller 1c-2 may be a sphere, an ellipsoid, a cylinder or a cone. Adjacent two first rollers 1c-2 are in partial contact with each other. The first roller 1c-2 is also in partial contact with the raceway 1c-1. In the case where two adjacent first rollers 1c-2 are in partial contact with each other, several rollers 1c-2 fill the raceway 1c-1 in such a way that the raceways 1c-1 are in partial contact with eac...

Embodiment 2

[0060] This embodiment may be a further improvement and / or supplement to Embodiment 1, and repeated content will not be repeated here. In the case of no conflict or contradiction, the whole and / or part of the content of the preferred implementations of other embodiments may serve as supplements to this embodiment.

[0061] Preferably, the axis of the rotary device 1 and the axis of the first transmission turntable 1b can be set in such a way that they do not coincide with each other but are in the same direction. Due to the eccentric setting of the first transmission turntable 1b, when the slewing device 1 rotates around its own axis, the first transmission turntable 1b rotates eccentrically around the axis of the slewing device 1, so that the rolling hole 1b-1 on the first transmission turntable 1b The dynamic friction pair is formed in discontinuous contact with the second roller 3 b - 3 on the first transmission member 3 , so that the first transmission member 3 rotates int...

Embodiment 3

[0063] This embodiment may be a further improvement and / or supplement to Embodiment 1, and repeated content will not be repeated here. In the case of no conflict or contradiction, the whole and / or part of the content of the preferred implementations of other embodiments may serve as supplements to this embodiment. This embodiment discloses a transmission device.

[0064] Preferably, the transmission device includes a slewing device 1 and a second transmission member 2 to realize one-stage transmission.

[0065] Or, preferably, the transmission device includes a slewing device 1 and a first transmission member 3 to realize a first-stage transmission.

[0066] Or, preferably, the transmission device includes a slewing device 1 , a first transmission member 3 and a second transmission member 2 to realize two-stage transmission. Its specific operation diagram is as follows figure 1 shown. The external power drives the second transmission part 2 as the active part with ω 2 Rot...

Abstract

The invention relates to a rotary transmission device and method. The rotary transmission device comprises a rotary device, wherein the rotary device comprises a base body; a roller path for accommodating a plurality of first rolling bodies is arranged on the base body; and under the condition that the base body rotates around the axis of the base body, at least one of the first rolling bodies can rotate around the axis of the rolling friction pair formed by the first rolling bodies and the roller path in a non-pure rolling mode and move along the roller path. The position relation between the roller path and the base body has invariance in the rotating process of the base body, so that the complexity of the setting position of a driving body on a second transmission piece can be reduced.

Description

[0001] This case is a divisional application with the application number 201910535454.1, the application date is June 20, 2019, the application type is an invention patent, and the application name is a slewing device for transmission, including its transmission equipment and transmission method. technical field [0002] The invention relates to the technical field of mechanical transmission, in particular to a rotary transmission device and a transmission method.
