Embodiment Construction

[0039] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0040] Figure 4 It is an assembly drawing of a first-stage gearbox with a flexible high-damping adjustable clearance structure. Its external structure mainly includes cover plates, boxes, large end covers, small end covers and shafts and other main components.

[0041] Figure 5 The exploded view of the gearbox is mainly composed of three parts: the driving gear-shaft system, the driven gear-shaft system and the box assembly. Among them, the driving gear-shaft system includes small end cover 2, variable clearance damping ring 4, push cylinder 5, driving bearing 7, driving gear 10, and driving shaft 11; the driven gear-shaft system includes large end cover 1, driven bearing 6, driven shaft 8 and driven gear 9. The box body assembly includes a box body 3 , an upper box cover 12 , an observation cover 13 and a gasket 14 .

Abstract

The invention discloses a self-adaptation variable-engaging-gap gear transmission device and method. The device comprises a driving shaft and a driven shaft, a driving gear is mounted on the driving shaft, a driven gear engaged with the driving gear is mounted on the driven shaft, driving bearings are mounted at the positions, on the two sides of the driving gear, of the driving shaft, the outer rings of the driving bearings are provided with variable-gap damping rings and push cylinders, the variable-gap damping rings are of annular structures including inner rings and outer rings, four crescent-moon-shaped grooves which are symmetrically staggered in pairs and located on the different radius positions are arranged between the inner rings and the outer rings, the push cylinders are oppositely mounted on the two sides of the variable-gap damping rings, cylinder rod ends of the push cylinders are fixedly provided with arc plates, and the arc plates make contact with the inner surfaces of the variable-gap damping rings. The system stable running working condition range can be obviously improved, the transmission precision can be improved, vibration and noise can be reduced, the system service life can be prolonged, and the equipment system reliability can be ensured.

Description

technical field [0001] The invention relates to a gear transmission device and a method, in particular to a gear transmission device and a method with adjustable meshing clearance. Background technique [0002] In the current gear transmission system, there is a certain gap b between the gear teeth and the meshing transmission. The main purpose of this gap is to provide lubrication space and prevent the phenomenon of meshing jamming, such as figure 1 shown. However, the size of the backlash 15 of the meshing teeth plays a decisive role in the stability of the system transmission. A certain gap can ensure that the system can maintain a stable working condition in a certain speed range. In other speed ranges, unstable multi-cycle or even chaotic motion states may occur, which will generate strong noise and vibration to the system. In addition, as the wear of the tooth surface increases, the gap will be too large, resulting in a change in the motion state of the system. [0...
