Description
Technical field
The utility model belongs to the hypoid generating machine technical field, particularly relates to a kind of numerical control helical bevel gear mill teeth machine workpiece box transmission device.
Background technology
The kind of drive of spiral bevel gear generator workpiece box mainly adopts gear drive in the prior art, and the gear drive rotating speed is high, but robust motion is poor, and therefore excesssive gap needs to remedy above-mentioned deficiency through gear clearance elimination mechanism.Traditional gear clearance elimination is to realize through adjusting two pin-and-hole and straight pins on the spur gear; Wearing and tearing occur because spur gear rotates for a long time, cause the gap between it increasing, need dismantle straight pin or punching again repeatedly; So cause the gap adjustment loaded down with trivial details, efficient is low.In addition, traditional spiral bevel gear generator workpiece box can't satisfy and can process the demand that the convergent tooth can be processed equal-depth teeth again owing to its structural limitations.
Summary of the invention
The utility model improves the Machinetool workpiece speed of mainshaft, motion is steady, noise is low and efficient is high and can satisfies the convergent tooth and the numerical control helical bevel gear mill teeth machine workpiece box transmission device of equal-depth teeth processing for the technical problem that exists in the solution known technology provides a kind of.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is:
Numerical control helical bevel gear mill teeth machine workpiece box transmission device; Comprise: workpiece casing, work spindle, servomotor; Work spindle is installed on the workpiece casing through bearing; It is characterized in that: also comprise the gear clearance elimination mechanism that is made up of driving gear, gear shaft, first gear train, second gear train and adjusting pad, through the direct suit driving gear of shaft coupling, said gear shaft one end is installed on the tool box through bearing on the motor shaft of servomotor; The other end is installed on the workpiece casing through bearing and bearing holder (housing, cover); On gear shaft, first gear train that is meshed with driving gear is housed, is provided with the adjusting pad that is used to adjust with the driving gear gap between said first gear train, two gears, second gear train is housed at the work spindle tail end through shaft coupling; The said driving gear and first gear train form first gear pair, and the said gear shaft and second gear train form second gear pair.
The utility model can also adopt following technical scheme:
Two gears of said second gear train are fixed through platen, screw, dish spring.
Also be provided with adapter sleeve, adjusting pad and the screw that is used for the second gear train axial location on the said work spindle tail end.
Advantage and the good effect that the utlity model has are: because the utility model adopts technique scheme; Promptly on workpiece spindle box, be provided with gear clearance elimination mechanism; Overcome two spur gears and rotated the appearance wearing and tearing for a long time; Need dismantle taper bolt or hinge pin hole and cause gap adjustment loaded down with trivial details again repeatedly, inefficient deficiency; Also can solve the gear drive bumpy motion simultaneously, excesssive gap, noise reach inefficient problem greatly, can satisfy the demand of processing convergent tooth and equal-depth teeth in addition.

The specific embodiment
For further understanding summary of the invention, characteristics and the effect of the utility model, the following examples of giving an example now, and conjunction with figs. specifies as follows:
See also Fig. 1, numerical control helical bevel gear mill teeth machine workpiece box transmission device comprises: workpiece casing 19, work spindle 18, electric machine support 2 and servomotor 1.The work spindle two ends are supported through pair of bearings 10 and are installed on the workpiece casing, and pass through the interior ring of locking nut 11 locking right-hand member bearings, on the work spindle tail end, also are provided with the adapter sleeve 17, adjusting pad 5 and the screw 13 that are used for the second gear train axial location.This workpiece box transmission device also comprises the gear clearance elimination mechanism that is made up of driving gear 3, gear shaft 20, first gear train 7, second gear train 15 and adjusting pad 5, on the motor shaft of servomotor 1 through shaft coupling 6 direct suit driving gears 3.Said gear shaft one end is installed on the tool box through bearing; The other end is installed on the workpiece casing 19 through bearing and bearing holder (housing, cover) 8; On gear shaft, first gear train 7 that is meshed with driving gear is housed through shaft coupling; In the present embodiment, said first gear train adopts two helical gears, is provided with the adjusting pad 5 that is used to adjust with the driving gear gap between said first gear train, two helical gears.At the work spindle tail end second gear train 15 is housed, in the present embodiment, said second gear train adopts two helical gears, and the said driving gear and first gear train form first gear pair, and the said gear shaft and second gear train form second gear pair.Two helical gears of said second gear train carry out axial restraint through platen 14, screw and dish spring 16, also can be through tightening and loosening screw and adjust the driving torque between two gears.
The operation principle of the utility model is:
Two helical gears of first gear train and adjusting pad 5 link together through screw, and Machining of Gear profile together.In installation process, driving gear 3 is meshed with two helical gears of first gear train 7 simultaneously, when gears engaged is gapped, eliminates two gaps between the helical gear through grinding adjusting pad 5.Gear shaft 20 is connected with main shaft casing 19 through bearing, and gear shaft is meshed with second helical gear of second gear train 15, and first helical gear is connected through screw with second helical gear through platen 14, and the dish spring is housed in platen.First helical gear and second helical gear and platen compress through the dish spring, change the frictional force between them through adjustment screw, and play the effect in the crack that disappears through frictional force.Because have frictional force between first helical gear and second helical gear and the platen, they also can play the effect of damping.Said gear shaft and first helical gear and gear shaft and the second helical gear centre-to-centre spacing and modulus are identical.
