Embodiment Construction

[0024] The laminated gear of the present invention can form various transmission modes according to transmission requirements. Such as Figure 1~2 The first type of spur gear shown is formed by superimposing several identical gear pieces 1 with tooth profiles 11 aligned, and the pieces are fixedly connected by rivets 2 . The thickness L of the tooth pieces on the left and right sides of the gear is greater than the thickness L' of the middle tooth piece.

[0025] Such as Figure 3-5 The second type of spur gear shown is composed of a number of identical gears 5 stacked in alignment with each tooth profile 11. Except for the outer gear 5', the rest of the gears are at a distance of radius R from the center of the circle. There are evenly distributed concave-convex points 12 punched on the circumference, and the convex part of the concave-convex point 12 of the previous tooth piece is embedded in the concave part formed by the concave-convex point of the next tooth piece; Con...

Abstract

The present invention relates to a gear and its production method. Said gear is made up by using several toothed sheets with identical tooth outline and superimposing them in the mode of aligning tooth profile or alternating them in a certain order, and fixedly connecting them. Its production method includes the following steps: punching thin sheet into toothed sheet, suporimposing toothed sheetsand connecting them together by mechanical process or adhesive process in the mode of aligning their tooth profile and alternating them according to a certain order to form a whole body gear.

Description

(1) Technical field [0001] The invention relates to a gear and a gear processing method. (2) Background technology [0002] The gear and its transmission in mechanical transmission rely on a special tooth profile to ensure its precise operation. Whether it is an involute gear or an arc tooth shape or other tooth shapes, special equipment and special tools are required to complete the processing of the gear. Due to the shape and accuracy requirements of the tooth profile, there will be differences in gear processing and gear performance. Various problems are traditionally solved by corresponding countermeasures. From gear selection to wheel blank formation to heat treatment, machining has formed a fairly complete process. [0003] However, due to the special shape requirements of the tooth profile of the gear, the gears required by different industries have different purposes and precision requirements. In order to meet the precision requirements of the gears, in addition t...
