Problems solved by technology

[0002] For a pair of meshing gears, if the parameters are not well selected, the teeth will be stuck and cannot rotate. This phenomenon is called interference, which will affect the transmission of the gears and damage the meshing parts of the accelerated gears, shortening the life of the gears.

Abstract

The invention discloses an anti-interference gear and a rolling cutter thereof used for machining capable of reducing interference amount of gear engagement. The tooth shape comprises following parameters: h-whole depth of tooth, h-xy: tip relief; hs-tooth addendum; sc1- arc tooth thickness; sj-string length; an-a pressure angle; afd-a tip relief angle; az-an increasing angle; and Rpfn-circular angles. An included angle, az, is formed by a first tooth surface and a second tooth surface. An included angle, afd, is formed by the second tooth surface and a vertical surface is a tip relief angle. The relations among the pressure angle am, the tip relief angle afd and the increasing angle az is afd equal to arctan(tan(an)+Delta / tan (0.4m) ); az is equal to afd-an. In the formula, m is the module of gears, delta is anti-interference amount of gears. The value range is 0.02 to 0.09. The anti-interference gear and the rolling cutter thereof used for machining have following beneficial effects: a simple structure is obtained; anti-interference amount of gear engagement is greatly decreased to facilitate using and improve service lifetime of gears.

Description

technical field [0001] The invention relates to a gear, in particular to a point-line meshing gear which can reduce interference when the gears mesh. Background technique [0002] For a pair of meshing gears, if the parameters are not well selected, the teeth will be stuck and cannot rotate. This phenomenon is called interference, which will affect the transmission of the gears and accelerate the damage of the meshing of the gears, shortening the life of the gears. Contents of the invention [0003] In view of the above-mentioned defects in the prior art, the technical problem to be solved by the present invention is to provide a gear capable of reducing the amount of interference during gear meshing and the hob teeth used for processing the gear. [0004] To achieve the above object, the present invention provides an anti-interference gear, the tooth shape of which includes the following parameters: h full tooth height, h- xy Trimming height, h s Addendum height, a n p...
