Description
Technical field
The present invention relates to hardened face gear precision processing technology field, particularly a kind of numerical control internal tooth honing wheel knife rest.
Background technology
High accuracy hardened face gear is requisite mechanical transmission component in the fields such as automobile, wind-power electricity generation, boats and ships, lathe, Aero-Space, high ferro.According to China Gear professional association statistics, China Gear market scale expects 2015 and reaches 2200-2500 hundred million yuan, and have benefited from the fast development of the industries such as automobile, wind-powered electricity generation, high ferro, the newly-increased gear market demand of more than 50% comes from these industries.Country's emphasis during " 12 " supports that the key technologies such as the long-life of the basic components such as gear, antifatigue, structure loss of weight, unstressed concentrated manufacture and assembling break through.The main purpose of Hardened gear face precision gear finishing step realizes the maximum bearing capacity of gear and minimum drive noise.High accuracy hardened gear finishing process is the effective manufacturing technology realizing high-quality gear maximum load capacity and minimum drive noise.The processing technologys such as traditional gear hobbing/gear shaping-shaving/roll flute-heat treatment cannot meet the requirement of gear in high-end dynamoelectric equipment in transmission accuracy, rotational noise and reduction manufacturing cost etc., and corresponding Hardened gear face method for fine finishing---powerful gear honing, skiving etc., become the dominant direction of Gear Manufacturing Technology research.
Since the later stage fifties in last century, external toothing gear honing process technology was applied by the U.S., gear honing process technology has become one of accurately machined main method of hardened face gear gradually.Research finds that gear honing can not only effectively reduce gear noise and surface roughness, and the distinctive surface texture featur that after gear honing, the flank of tooth is formed can strengthen flank of tooth wearability, makes a kind of fine-processing technique that gear honing becomes conventional after hardened face gear grinding.Tradition gear honing process technology exists the top gem of a girdle-pendant, and to cut surplus little, and the highest only have 10-15 μm of cutting output; Crudy depends on one manufacturing procedure (shaving etc.) and ensures; Profile of tooth after the top gem of a girdle-pendant, teeth directional capability for correcting are poor; Honing wheel adopts epoxide resin material manufacture, and precision is lower, and service life is short, the not high defect of Gear shape process precision.The application making the free top gem of a girdle-pendant cut processing is subject to certain restrictions, for removing the residual stress after heat treatment, smoothing, touching and knock and the aided processes such as deburring, for after grinding being reduction High-performance gear noise, strengthen flank of tooth compression, improve the occasions such as the service life of gear, the larger development constraining gear honing process technology.
After heat treatment, Hardened gear face method for fine finishing mainly contains Hardened gear face shaving, Hardened gear face roll flute, Hardened gear face essence roll and Hardened gear face gear honing etc.When hardened face gear machining accuracy controls in the precision that ISO5 level is even higher, under the prerequisite that manufacturing cost maintains an equal level, powerful gear honing process technology can meet the requirement of high-end equipment to transmission performances such as the accuracy of gear, bearing capacity, movement rate, stationarity, working life and noises.Wideling popularize employing gear hobbing-heat treatment-this new process for processing of powerful gear honing abroad at present, but domestic extensively popularizing also has difficulties.
The powerful gear honing processing of numerical control internal honing wheel applies internal tooth wheel shape honing wheel and taken turns by gear honing to do engaged transmission, is equivalent to a pair crossed helical involute gears, utilizes the relative sliding velocity between its flank of tooth and pressure to carry out a kind of flank of tooth method for fine finishing of honing.The powerful gear honing machine of numerical control internal honing wheel is the key equipment of the accurate external tooth of batch machining, duplicate gear, shaft gear, barreled tooth flank, can to harden or the cylinder of non-hardenable is straight, bevel wheel machining.Gear honing production efficiency is high, and cost is low, can reduce grating of gears, improves gear capacity, extends gear life, and reduce tooth-face roughness, tooth-face roughness can be machined to below Ra0.63um, the accuracy of gear can reach 6 ~ 7 grades.For the processing of external tooth top gem of a girdle-pendant wheel gear honing, it has higher profile of tooth and tooth pitch precision.Interior honing wheel knife rest realizes one of topmost functional part of above-mentioned process, but existing interior honing wheel cutter frame structure is single, can not meet the eurypalynous demand in market.
Summary of the invention
Given this, the numerical control internal tooth honing wheel knife rest providing a kind of structure simple and easy to use is necessary.
