Abstract
A method and machine for using the numerally controlled abrasive band to grind the teeth of cycloid gear features that a pilot wheel is used to make the abrasive band become a cylindrical grinding tool, the whole width of tooth is simultaneously ground, and the abrasive band is reciprocating for polishing the ground surface.
Description
One, technical field
The invention belongs to the gear manufacturing under the mechanical manufacturing field.
Two, background technology
The cycloid gear reductor has big, the advantage of simple structure of speed reducing ratio, and has obtained to use widely, and the vital part of cycloid speed reducer is a cycloid gear, and this gear need quench and grinding.For many years, gear rotation when cycloidal gear grinding machine all adopts the work of mock pendulum line gear reductor and the disk wheel teeth grinding method of revolution, the productivity ratio of this method is very low, thereby has increased the cost of cycloid gear reductor, and has limited the extensive use of cycloid speed reducer.Along with development of numerical control (NC) technology, and the appearance in high efficiency abrasive band, make the cycloid gear roll flute new favourable turn occur.
Three, summary of the invention
The purpose of this invention is to provide a kind of Numeric Control Technology used, develop into cycloid gear widths over teeth grinding by the pointwise grinding, the good especially abrasive band of grinding force of putting sand with modern static is the new teeth grinding method and the device of instrument, to improve the productivity ratio and the precision of cycloid gear roll flute.
Technology contents of the present invention is: a kind of cycloid gear numerical control abrasive band teeth grinding method and device, comprise the motor in revolution work, horizontal rolling guide rail, vertical scrolling guide rail, ball screw, drive abrasive band and belt raising speed transmission system, abrasive band guide wheel and clamping system, abrasive band balance abrasion system, it is characterized in that: utilize directive wheel to become cylindrical grinding tool to finish efficient widths over teeth grinding abrasive band appearance.
Being characterized as of this abrasive band mill method: although the directive wheel diameter is less, the abrasive band girth is longer, and when gram had been answered the cylindrical grinding wheel grinding, the emery wheel girth was subjected to the problem of diameter restriction.
The technology characteristics of cycloid gear is the ruled surface of loop configurations, is suitable for the two coordinate digital control system appearance method grinding of employing based on the polar coordinates motion, and when promptly workpiece rotated, grinding tool was done corresponding radial motion.The curve at grinding tool center is the equal space line of cycloid.
Because it is milder that the cycloidal profile of workpiece rises and falls, so can utilize bigger lead diameter grinding, the radius of lead exceeds with the radius of curvature at cycloidal profile tooth root place.
Can be with the directive wheel of same diameter, the cycloid gear of grinding plurality of specifications is as long as the radius of directive wheel is less than the radius of curvature of cycloid gear tooth root.

Fig. 1 is the schematic diagram of cycloid gear sbrasive belt grinding method, and it also is the side view of Fig. 2.
Fig. 2 is the schematic diagram of cycloid gear sbrasive belt grinding method, and it also is the top view of Fig. 1.
Fig. 3 is the apparatus structure schematic diagram of cycloid gear sbrasive belt grinding method, and it also is the side view of Fig. 4.
Fig. 4 is the apparatus structure schematic diagram of cycloid gear sbrasive belt grinding method, and it also is the top view of Fig. 3.
Concrete implementation step:
Below in conjunction with accompanying drawing, this method and device are described further.
Fig. 1 and Fig. 2 are cycloid gear sbrasive belt grinding method figure, and the flank profil M of cycloid gear 5 is a cycloid, straight-tooth, because thickness is less, generally adorns one or more pairs of while grindings, the ruled surface flank profil of this annular spread, be suitable for and adopt polar coordinates to form, when promptly workpiece rotates A, the reciprocal radial motion X of grinding tool.The track N that tool focus moves is the equal space line of cycloid M, and both distances are the directive wheel radius R.The abrasive band after the belt raising speed, drives O by motor
3The driving wheel at place drives, and produces ablation.Directive wheel makes soft abrasive band be configured as columniform grinding tool, and directive wheel is with the nonslipping rotation in abrasive band.Use regulating wheel O
5The tensioning abrasive band, regulating wheel makes the abrasive band be in tensioning state by spring all the time.The workpiece flank profil that grinds is the envelope M that lead moves along the N curve.
Fig. 3 and Fig. 4 are cycloid gear abrasive belt grinding device structural representation.Device is made up of following parts: the 1-body; The 2-slide carriage; The 3-rotary table; The 4-anchor clamps; The 5-workpiece; The 6-pressing plate; The 7-binding nut; The 8-abrasive band; The 9-directive wheel; The 10-support; The 11-driving wheel; The 12-bistrique; The 13-rolling guide; The 14-column; The 15-toggle.For the reasonability of structure, the building motion of numerical control two coordinate cycloid; The rotation A of workpiece is finished by rotary table.The radial motion X of workpiece is finished by slide carriage.On bistrique 12, motor and one-level belt raising speed are housed, to guarantee the optimization grinding speed (not marking among the figure) in abrasive band, drive abrasive band driving wheel 11 then and rotate, therefore, drive abrasive band 8, directive wheel 9 and regulating wheel and rotate, finish grinding motion.Because the abrasive band is wideer than workpiece, therefore, the abrasive band is the widths over teeth of grinding work piece simultaneously.After treating that workpiece rotates a whole circle, the abrasive band is whole flank of tooth of energy grinding cycloidal profile just.Behind the workpiece mill one whole circle, numerical control program makes slide carriage make radial feed Δ X and regrinds second time, till the outside dimension that is ground to the cycloid gear requirement.
For making Wear Mechanism of Abrasive Belt even, and the uniformity on cycloid gear surface, in grinding process,, bistrique is moved up and down slowly also by driven by motor toggle 15.Because between bistrique and the column is rolling guide, and balance weight is arranged, therefore, so that motion is very steady up and down.
When changing the abrasive band, need only rise upper bracket 10 can finish.
