Description
Technical field
The utility model belongs to the gear machine technical field, particularly relates to a kind of numerical control tooth grinder for spiral bevel gear eccentric main axis mechanism.
Background technology
Numerical control tooth grinder for spiral bevel gear is used at a high speed, grinding spiral bevel gear accurately, its objective is the distortion after the profile shifted gear heat treatment, improves tooth accuracy and fineness, the requirement that reach stable drive, reduces noise and improve precision.Spiral bevel gear grinding machine generally adopts single face grinding and enlarging cup emery wheel double-side grinding when grinding bevel gear bull wheel at present, and the former grinding efficiency is low, and the latter is more expensive because of enlarging cup emery wheel price, and difficulty is big during trimming wheel, is unfavorable for producing.If carry out double-side grinding with common straight cup shape emery wheel, owing to be subjected to the restriction of grinding wheel spindle structure, this moment emery wheel and flank of tooth comprehensive engagement, cooling fluid can't enter, and causes flank of tooth large-area burns, can't adapt to the development of today's numerical control lathe.
Summary of the invention
The utility model provides a kind of processing accurate for solving the technical problem that exists in the known technology, precision height, the numerical control tooth grinder for spiral bevel gear eccentric main axis mechanism that efficient is high.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is:
A kind of numerical control tooth grinder for spiral bevel gear eccentric main axis mechanism, it is characterized in that: comprise casing, the casing left side first half is fastened with ring flange A by securing member, be coated with little axle by bearing in the ring flange A, the left side of ring flange A is equipped with the spindle motor installation sleeve, spindle motor installation sleeve left end is fixed with spindle motor, and little axle left end links to each other with spindle motor by shaft coupling, and the right-hand member of little axle is equipped with gear A; In the casing right-hand part spindle jacket is installed, be coated with eccentric main axis by bearing in the spindle jacket, be coated with grinding wheel spindle by bearing in the eccentric main axis, the grinding wheel spindle left end is coated with gear B, gear A and gear B engagement, the grinding wheel spindle right-hand member is equipped with emery wheel by ring flange C; The left end of eccentric main axis is fastened with support set by securing member, is fastened with gear C by securing member on the support set; Casing left side Lower Half is equipped with and connects cover, connect in the cover and be coated with eccentric shaft by bearing, the eccentric shaft right-hand member is coated with gear D, gear D and gear C engagement, the eccentric shaft left end is coated with gear E, connects the cover left side ring flange B is installed, and ring flange B left side is equipped with the eccentric shaft motor, be coated with gear F on the eccentric shaft motor, gear F and gear E engagement.
The utility model can also adopt following technical scheme:
Described securing member is a screw.
Advantage and the good effect that the utlity model has are: the technical solution of the utility model has adopted two main shafts, be grinding wheel spindle and eccentric main axis, grinding wheel spindle is packed in the eccentric main axis endoporus, making grinding wheel spindle can also follow eccentric main axis in rotation revolves round the sun together, produce an eccentric motion and can reach creep feed grinding, thereby make emery wheel produce contacting of clearance-type with the teeth groove flank of tooth.The eccentric gap that produces constantly enters cooling fluid to be ground the flank of tooth and does not burn, and can reach maximum grinding and feeding amount simultaneously as far as possible.
