Structure and manufacturing method of light load gear

Abstract

The invention discloses a structure and a manufacturing method of a light load gear. A convex platform and a concave platform which are matched are respectively arranged on an internal round surface of a gear ring and an external round surface of a hub of the light load gear. A spoke is made of engineering plastics, such as polycarbonate (PC), polyamide (PA) and polyformaldehyde (POM). The spoke is fixed on the central position of the gear ring through a mould, the spoke melt at high temperature is pressed through the mould and is filled in a space between the hub and the gear ring, and after the spoke is cooled, the spoke, the hub and the gear ring form the uniform integral gear. The structure and the manufacturing method of the light load gear have the advantages of being easy to manufacture, saving metal materials, and being low in cost, relatively small in vibration in the transmission process, small in noise, and favorable for environment protection.

Description

technical field [0001] The invention relates to a light-load gear structure and a manufacturing method thereof, belonging to the technical field of mechanical parts and mechanical transmission. Background technique [0002] Gears are commonly used parts in mechanical transmission. At present, gears are generally manufactured by metal cutting. For some light-loaded gears, there are also cold stamping methods. No matter the gears manufactured by metal cutting or stamping , these gears are all in the form of an integral metal structure. Although the gears of this structure have the advantage of bearing a large load, for some light-loaded transmission mechanisms, for example: signal transmission and In the transmission mechanism of the transmission, the gears of this integral metal structure have the defects of serious waste of metal raw materials and high cost. In addition, these metal gears of the integral structure also have relatively large vibration and high noi...
