TL;DR: In this article, a gear processing technology for improving gear grinding efficiency is presented, which comprises the steps that a tooth profile of a gear part is obtained from a blank through a hobbing or gear shaping technology; the gear deformation amount is calculated according to gear materials, sizes and an adopted heat treatment technology; according to the calculated deformation amounts, the tooth surface of the gear is shaved by a gear shaving machine, the gear processed by shaving is subjected to a heat treatment process; and the gear obtained after heat treatment is finished by a grinding machine.
Abstract: The invention provides a gear processing technology for improving gear grinding efficiency. The gear processing technology comprises the steps that a tooth profile of a gear part is obtained from a blank through a hobbing or gear shaping technology; the gear deformation amount is calculated according to gear materials, sizes and an adopted heat treatment technology; according to the calculated deformation amount, the tooth surface of a gear is shaved by a gear shaving machine; the gear processed by shaving is subjected to a heat treatment process; and the gear obtained after heat treatment isfinished by a gear grinding machine. According to the gear processing technology for improving the gear grinding efficiency, the gear is subjected to heat treatment pretreatment according to the geardeformation amount by using the gear shaving technology, then heat treatment and gear grinding shaping are carried out, since the efficiency of the gear shaving process is 10 times or more of that ofgear grinding, the gear grinding efficiency can be significantly improved, and the machining accuracy and quality of the gear are ensured.

TL;DR: In this paper, a full-automatic gear shaping machine for sprocket hubs of bulldozers is proposed, where the conical component and the body are fixedly connected to form an integral structure with the same conical degree, and accordingly the cutter and tabletop of the tooling form an inclination angle of 1 degree, 47 minutes and 43 seconds.
Abstract: The utility model relates to a full-automatic gear shaping machine for sprocket hubs of bulldozers. The full-automatic gear shaping machine aims to resolve problems that a traditional gear shaping machine cannot achieve the effect of optional matching of produced sprocket hubs with gear hubs, and brings enormous difficulty in integral assembly and massive production for an assembly plant. The full-automatic gear shaping machine for sprocket hubs of bulldozers comprises a body, a conical component, a cutter and a tooling, the conical degree of the conical component is 1 degree, 47 minutes and 43 seconds, the conical component and the body are fixedly connected to form an integral structure with the same conical degree, and accordingly the cutter and a tabletop of the tooling form an inclination angle of 1 degree, 47 minutes and 43 seconds. By the aid of the conical component, a machined sprocket hub is a conical gear with the conical degree of 1 degree, 47 minutes and 43 seconds, and the effect of optionally matching of the machined sprocket hub with a machined gear hub with the same conical degree is achieved, assembly of the integral machine is accelerated, work efficiency is improved, and the full-automatic gear shaping machine can be widely applied to production of sprocket hubs of bulldozers.
