Embodiment Construction

[0022] see figure 2 , the tooth meshing transmission part applied to the precision mechanical structure of this embodiment includes a circular thin sheet body 1, a rotating shaft 2 passing through the center of the body 1, and the outer edge of the circumference of the body 1 is formed with axially divided There are two layers of meshing teeth groups 3, and the tooth shapes and tooth pitches of the meshing teeth 4 in the two layers of meshing teeth groups 3 are the same, and the meshing teeth 4 adjacent to each other are staggered in the circumferential direction, thus forming Staggered plate gears.

[0023] see image 3 , showing a gear pair consisting of two staggered plate gears as described above. In both gears, the toothing 4 on the corresponding level meshes with each other in the usual manner. And between the layers, since the adjacent meshing teeth 4 are staggered from each other along the circumferential direction, a first meshing tooth 4A of the driving gear and ...

Abstract

The invention provides a tooth engagement transmission part applied to a precise mechanical structure. The tooth engagement transmission part comprises a body (1), wherein the outer edge of at least one part of the body (1) is provided with an engagement tooth group (3) which takes a rotating shaft of the body (1) as a center, has the same radius and is in arc arrangement. The tooth engagement transmission part is characterized in that the body (1) is in a flake shape, engagement teeth (4) are divided into two layers along the axial direction, the two layers of engagement teeth (4) are the same in tooth form and tooth space, and adjacent engagement teeth (4) between the two layers are mutually staggered along the circumferential direction. The tooth engagement transmission part is stable and precise in engagement, continuous and smooth in transmission and convenient to process.

Description

technical field [0001] The invention relates to a tooth meshing transmission part applied to a precision mechanical structure, especially a tooth meshing transmission part on door locks and clocks. Background technique [0002] In the prior art, gear meshing transmission is widely used in various mechanical transmission devices because of its compact structure, large transmission power, high mechanical efficiency, and accurate transmission ratio. In the precision mechanical structure, due to the limitation of the mechanical scale, the gear transmission is usually in the shape of a sheet. For example, the Chinese patent document CN201614810U discloses a three-gear transmission mechanism of a mortise door lock, wherein a combined square core is provided between the oblique deadbolt assembly and the square deadbolt assembly for lifting and lowering the handle inside and outside the door. 1. The intermediate gear that plays a transmission role and the lock cylinder gear that ca...
