Various-modulus grinding method of end surface gear disc

Abstract

The invention relates to a various-modulus grinding method of an end surface gear disc. The method comprises the following steps: the end surface gear disc to be grinded after rough milling of the gear surface is mounted on an indexing mechanism; a gear-shaped angle of a grinding wheel on a grinding machine is finished; a center axle I of the end surface gear disc to be grinded is aligned; a gear groove center axle II of any symmetric gear groove is aligned; an intersecting point of a large end diameter D1 of the end surface gear disc to be grinded and the gear groove center axle II is used as an initial point; the grinding wheel moves to the intersecting point A, and is tangential to the same; according to setting of the end surface gear disc, and according to end surface gear disc parameters set by the grinding machine, a single-edge large end difference value L of a 1 / 2 difference value between two large end diameters is obtained; the grinding wheel flatly moves to a point B by the single-edge large end difference value L, so that the grinding wheel is tangential to the point B as a gear grinding starting point; and the gear groove is grinded according to the end surface gear disc parameters set by the grinding machine to manufacture a various-modulus end surface gear disc.the method can realize grinding of end surface gears with various modulus on a traditional machine tool, is convenient for operation, and can improve the generality and the production efficiency of the machine tool equipment.

Description

technical field [0001] The invention relates to a grinding processing method of variable modulus of an end face gear plate, which belongs to the technical field of end face gear plate processing. Background technique [0002] The connection of the face gear has the characteristics of high transmission torque and self-centering. It is often necessary to use the face gear connection transmission in rail transit, gas turbines and machine tools. There are usually two methods for the processing of high-precision end tooth discs: one is to perform index milling on a machining center or milling machine, and then pair them on a grinding machine to grind them to improve the accuracy of the pair of end tooth profiles. The disadvantage of this method is that the efficiency is low, and it must be assembled and used in pairs after grinding, there is no interchangeability, and the use cost is high. Another method is to rough mill the teeth on the machining center or milling machine first...

Problems solved by technology

However, there are currently no special grinders on the market that do not have an end tooth disc. Generally, an indexing mechanism is added to the surface grinder to realize the grinding of the end tooth disc. This modified machine tool is limited by the original mechanism and program of the machine tool. Usually, one The grinding machine can only be used to process the face gear of one modulus, resulting in poor versatility of the machine tool equipment
