Embodiment 1

[0016] This embodiment provides a production process for fully quenching high-hardness scale gears, characterized in that the production process includes the following steps:

[0017] A. Select the materials of ring gear (1), wheel hub (2) and sub-plate (3) according to the needs of manufacturing scale gears;

[0018] B. Determine the basic process route for processing the ring gear (1), hub (2) and sub-plate (3), and process them separately:

[0019] a. Process the ring gear (1): select the ring gear forging, normalize after forging, rough turn the two ends of the ring gear and the inner and outer circles of the ring gear, and leave a margin of 12-15mm for the length and diameter of the ring gear. Chamfering on both sides of the outer circumference of the ring gear, then quenching and tempering treatment, and finally turning before welding, leaving a margin of 5-8mm for the length of both ends of the ring gear, and turning the inner circle to the required size before welding,...

Abstract

Disclosed is a production technology of a fully-quenched high-hardness scale gear. The production technology of the fully-quenched high-hardness scale gear is characterized by comprising the following steps of selecting gear materials; determining a basic process route in the machining process of a gear ring, an accessory plate and a hub; machining the gear ring, the accessory plate and the hub respectively; and machining the gear wholly. The production technology of the fully-quenched high-hardness scale gear has the advantages that the welding labor intensity is reduced, the production efficiency is improved, and the welding quality stability is ensured; and the production technology is suitable for being used and popularized in a large-area manner.

Description

technical field [0001] The invention relates to the field of production technology of scale gears, and in particular provides a production process of fully quenched high-hardness scale gears. Background technique [0002] The existing large gears have a relatively large modulus and diameter. Generally, when manufacturing gears, the integral blank is forged according to the traditional production method, and the gears are hobbed after turning, and then processed by carburizing, quenching, and grinding, which not only wastes materials , and heat treatment will also cause low hardness due to insufficient quenching, large heat treatment deformation, high cost, low yield, and cannot be widely used. Contents of the invention [0003] The object of the present invention is to solve the above-mentioned existing problems, and especially provides a production process for fully quenching high-hardness scale gears. [0004] The invention provides a production process for fully quench...
