The planet circular system of forming by sun gear, planetary gear and internal gear be automatic transmission, hub reduction gear and planetary reducer mainly subtract (change) fast member.At present, sun gear and planetary gear have been realized high efficient grinding, therefore improve the accuracy of manufacture of planet circular system, increase its bearing capacity, and key is the grinding problem that will solve hard flank of tooth internal gear.Owing to lack high efficiency grinding machine, homemade internal gear generally adopts modified and tooth-face strengthening technology nitrogenize, and this heat treatment method requires flank of tooth quenching and tempering hardness height, causes gear shaping efficient low; Not grinding after the heat treatment, the accuracy of gear reach 7 grades at most.Once had enterprise to attempt to change gear material into mild steel, tooth-face strengthening adopts carburizing and quenching, and the working (machining) efficiency and the tooth face hardness of gear are improved, but precision is reduced to below 8 grades, can't use at all.
The utility model content
In order to solve the problem of above-mentioned existence, the utility model provides a kind of internal gear moulding grinding machine bed, can carry out the high efficiency roll flute to internal gear.
The utility model is to adopt following technical scheme to realize:
Described internal gear moulding grinding machine bed, the grinding machine head of this grinding machine bed is installed on the vertical slide unit, and vertical slide unit is installed on the column of this grinding machine bed, and column is installed on vertical slide unit, and vertically slide unit is installed on the base of this grinding machine bed; Internal gear is installed on the panoramic table, and the axis normal of internal gear is placed, and the direction of displacement of vertical slide unit is identical with the axis direction of internal gear, and panoramic table is installed on the horizontal slide unit, and laterally slide unit is installed on the base of lathe; Dresser can be installed on the panoramic table, also can be installed on the horizontal slide unit.
Described internal gear moulding grinding machine bed, the emery wheel on the grinding machine head of this grinding machine bed is connected with grinding motor by belt.
Described internal gear moulding grinding machine bed, the panoramic table of this grinding machine bed can be a numerical control turntable, also can be the machinery rotation platform.
Described internal gear moulding grinding machine bed, the vertical slide unit of this grinding machine bed, horizontal slide unit and vertical slide unit can be nc sliding tables, also can be mechanical skid plateform or hydraulic pressure moving platform.
Described internal gear moulding grinding machine bed, the column of this grinding machine bed can be directly installed on the base of this lathe, and panoramic table is installed on the horizontal slide unit, and laterally slide unit is installed on vertical slide unit, and vertically slide unit is installed on the base of this grinding machine bed.
Described internal gear moulding grinding machine bed, the axis direction of the emery wheel of this grinding machine bed can be vertical mutually with Gear axis, also can be mutual out of plumb, i.e. the angle of the axis of rotation of emery wheel rotation is the helical angle of gear.
Owing to adopted technique scheme, the utility model to obtain following effect:
The utility model is easy to high efficient grinding owing to do not need model to become processing after the heat treatment, the accuracy of gear can reach 6 grades; Adopt the mild steel carburizing and quenching, flank of tooth intensity height not only, and need not modifiedly before the heat treatment, Gear Shaping efficient is very high.This can the lathe of internal gear high efficiency roll flute being widely used in industry is specially adapted to the internal gear in automatic transmission, hub reduction gear and the planetary reducer is carried out roll flute.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
The specific embodiment:
As shown in Figure 1, the utility model comprises grinding machine head 1, vertical slide unit 2, panoramic table 3 and two horizontal slide unit 4 and vertical slide units 5 that energy moves perpendicular to the internal gear axis of rotation.Grinding machine head 1 is installed on the vertical slide unit 2, and vertical slide unit 2 is installed on the column of this grinding machine bed, and column is installed on vertical slide unit 5 and can vertically moves with vertical slide unit 5, and vertically slide unit 5 is installed on the base of this grinding machine bed; Internal gear is installed on the panoramic table 3, and the axis normal of internal gear is placed, and the direction of displacement of vertical slide unit 2 is identical with the axis direction of internal gear, and panoramic table 3 is installed on the horizontal slide unit 4, and laterally slide unit 4 is installed on the base of lathe; Emery wheel on the grinding machine head 1 is driven by grinding motor, make the emery wheel high speed rotary by belt transmission, emery wheel leans on the cross grinding flank of tooth perpendicular to self axis of rotation, and vertical slide unit 2 pumps, grinding machine head 1 makes the whole facewidth obtain grinding with vertical slide unit 2 motions; During the grinding internal spur gear, the coordinated movement of various economic factors of controlling vertical slide unit 2 and panoramic table 3 is carried out form grinding to the flank of tooth of internal gear; The every grinding flank of tooth of emery wheel once, during leaving side, panoramic table 3 real-time calibration, driven gear turns over a tooth, all grinding is intact up to whole teeth.The indexing accuracy of panoramic table 3 will be enough to guarantee pitch error; Panoramic table 3 can be a numerical control turntable, also can be the machinery rotation platform; Move horizontal slide unit 4 and can control transverse tooth thickness and profile angle, move the grinding depth that vertical slide unit 5 can be controlled tooth; Vertical slide unit 2, horizontal slide unit 4, vertical slide unit 5 can be nc sliding tables, also can be mechanical skid plateform or hydraulic pressure moving platform.Dresser is implemented online finishing, and it can be trimmed to involute with the shaft section of emery wheel by the relative motion of horizontal slide unit 4, vertical slide unit 5 and panoramic table 3; Dresser can be installed on the panoramic table 3, also can be installed on the horizontal slide unit 4; Therefore, two kinds of methods can be arranged during trimming wheel: a kind of is that golden steel wheel is installed on the panoramic table 3, emery wheel is by the motor-driven high speed rotary, form the angular displacement of mechanical drive train control panoramic table 3 and the straight-line displacement of mobile horizontal slide unit 4 by digital control system control or by change gear, come the grinding end face of trimming wheel, make internal gear obtain required involute flank by form grinding; Another kind is to use golden pen trimming wheel, and golden pen is installed on the horizontal slide unit 4, controls horizontal slide unit 4 and the vertically relative motion of slide unit 5, the grinding end face of trimming wheel.
