Abstract

The invention discloses a method and a machine tool for machining a hypoid gear pair and aims to solve the problem that the hypoid gear pair is difficultly machined in the prior art. The machining method comprises the following steps of: 1, machining a big gear surface, namely 1) machining the right gear surface of a big gear; and 2) machining the left gear surface of the big gear; and 2, machining a small gear surface, namely 1) machining the left gear surface of a small gear; and 2) machining the right gear surface of the small gear. The machining machine tool comprises a workpiece shaft, a power head, a tilting working table, a rotary working table, an XYZ working table and a body, wherein the workpiece shaft replaces an original power spindle head of the conventional machine tool; the rotary working table is fixedly arranged on the XYZ working table and makes rotating axes of the rotary working table and the workpiece shaft coplanar; the tilting working table is fixedly arranged on the rotary working table; an inclined angle chi is formed between the upper surface of the tilting working table and the bottom surface of the tilting working table; and the power head is fixedly arranged on the tilting working table through a bolt, a guide rail and a guide rail groove.

Description

technical field [0001] The invention relates to a processing method and processing equipment for a gear pair, more precisely, the present invention relates to a processing method and a processing machine tool for a hypoid gear pair. Background technique [0002] In the space-staggered shaft transmission, the hypoid gear pair based on the theory of space-staggered shaft transmission usually uses a relatively simple conical surface instead of a single leaf hyperboloid as the indexing surface, and cuts teeth on the surface. It constitutes a hypoid-conical gear transmission, in which the bevel gears are mostly arc teeth and cycloidal teeth. The methods of Gleason and Olikon are the most widely used in the design and machining of hypoid gear pairs. [0003] The shape of the tooth surface of the hypoid gear can be in various forms, as long as the curved surface satisfies the principle of conjugate mesh transmission, it may be used as the tooth surface. Like the spiral bevel gear...
