Abstract

The invention discloses a heat treatment technology of high-strength flexible wheels used for a harmonic rotating speed machine. The heat treatment technology of the high-strength flexible wheels used for the harmonic rotating speed machine comprises the following steps: (1) pre-cleaning workpieces, and stacking the workpieces in a workpiece tray to complete feeding; (2) conducting pre-heating treatment on a heating furnace, wherein the temperature of a hearth ranges from 350 DEG C to 450 DEG C, and heating and heat preservation are conducted for 1 h to 2 h; (3) feeding the workpieces into the heating furnace for heating treatment, wherein the temperature of the hearth ranges from 840 DEG C to 870 DEG C, and heating and heat preservation are conducted for 1 h to 2 h; (4) putting the workpieces into quenching liquid for isothermal quenching treatment to obtain finished products of the high-strength flexible wheels used for the harmonic rotating speed machine, wherein the quenching temperature ranges from 310 DEG C to 330 DEG C; and (5) draining, cleaning, detecting and discharging the finished products of the high-strength flexible wheels used for the harmonic rotating speed machine. According to the heat treatment technology of the high-strength flexible wheels used for the harmonic rotating speed machine, on the premise that the conditions such as material components, size and design of an existing flexible wheel machining technology are kept unchanged, the strength and fatigue performance of the final finished products are significantly improved by optimizing the heat treatment process.

Description

technical field [0001] The invention relates to a processing technology of a flexible wheel, in particular to a heat treatment process of a high-strength flexible wheel for a harmonic speed machine, and relates to the technical field of material processing. Background technique [0002] Harmonic reducer is a kind of mechanical equipment widely used in the field of mechanical transmission. It has many advantages such as large reduction ratio, small backlash, high precision and efficiency. Generally speaking, a complete harmonic reducer includes at least three main parts: rigid wheel, flexible wheel and wave generator. Among them, the rigid wheel is an inner ring gear with high rigidity; the flexible wheel is cylindrical and made of less rigid material. In the middle of the wheel, its external teeth mesh with the internal teeth of the rigid wheel; the wave generator is an elliptical columnar structure, which extends into the mouth end of the flexible wheel. When the wave gen...
