Abstract
The utility model relates to a novel skewed tooth gear shaping mechanism, it includes lathe main motion crank dish, installs the bulb pull rod on the lathe main motion crank dish, and bulb and the sphere cover assembly of bulb pull rod cooperate and constitute the bulb and is connected, and the sphere overlaps assembly lower sleeve internally mounted has the ball screw axle, and ball screw axle and screw -nut cooperate, and screw -nut fixed mounting is in the inside of worm wheel, the worm wheel constitutes the worm gear transmission with the worm to through flange dish fixed mounting in the inside of knife rest, helical type gear shaper cutter fixed mounting is at the ball screw the tip of the axis. This skewed tooth gear shaping mechanism adopts ball screw to substitute traditional mechanical guide rail and uide bushing, and application ball screw's unfortunate lot running fit worm gear transmission reaches the purpose of cutting helical gear.
Description
Technical field
The utility model relates to gear shapping machine equipment technical field, particularly relates to a kind of novel helical teeth gear shapping machine structure, is applicable to the helical gear processing little helical pitch (being less than 100mm), is particularly suitable for helical teeth in processing minor diameter.
Background technology
At present, traditional helical teeth blade adapter for gear shaper structure adopts mechanical spiral guide rail mostly, and mechanical spiral guide rail moves up and down in fairlead, and the helical pitch of mechanical guide is equal with cutter helical pitch, uses when this structure is suitable for guide rail helical pitch comparatively large (being greater than 300mm).When required guide rail helical pitch is less, the mechanical helical guideway structure of tradition can be similar to sees a screw as, the tooth abdomen of screw and crest are guide pass and the periphery of helical guideway, and in the course of the work, this mechanical spiral guideway exists the shortcoming of the following aspects:
1, guideway contact surface is excessive, and during slotting, frictional force is comparatively large, generate heat more severe, and then causes guide rail and fairlead easily to generate heat be out of shape, and heating degree is different, and then causes being out of shape inconsistent, easy generation expansion loss.
2, because guide rail helical pitch is little, the main motion power overwhelming majority is used for overcome friction, and only have small part for cutting, cutting force is little.
3, because guide rail helical pitch is little, there is wedge angle with back-out place in being threaded into of guide rail, and guide rail is very easy to wearing and tearing, needs frequent grinding pretension.
4, panel processing difficulties in fairlead.
Process the gear of little helical pitch according to above structure, not only stock removal action cannot ensure, and cuts unable, also easily causes the wearing and tearing of mechanical spiral guide rail.
Utility model content
The purpose of this utility model is exactly for above-mentioned Problems existing, novel helical teeth gear shapping machine structure is provided, this helical teeth gear shaping mechanism adopts ball screw to come alternative traditional mechanical guide and fairlead, uses the inverse running of ball screw to coordinate Worm Wheel System to reach and cuts helical gear object.
For achieving the above object, design of the present utility model is: a kind of novel helical teeth gear shapping machine structure, it comprises lathe main motion crank disc, lathe main motion crank disc is provided with ball-head tension rod, bulb and the sphere of ball-head tension rod overlap assembly and match and form bulb and be connected, sphere cover assembly lower sleeve inside is provided with ball screw axle, ball screw axle matches with feed screw nut, feed screw nut is fixedly mounted on the inside of worm gear, described worm gear and worm screw form Worm Wheel System, and the inside of knife rest is fixedly mounted on by ring flange, helical gearshaper cutter is fixedly mounted on ball screw the tip of the axis.
The top of described ball screw axle is arranged on the inside of sphere cover assembly by the angular contact bearing that two are installed dorsad.
The utility model has following beneficial effect:
1, adopt ball leading screw driving to coordinate and substitute traditional mechanical screws auxiliary driving cooperation, the friction between friction pair can be reduced, thus decrease the generation of heat, prevent feed screw nut from producing overheating deforming, extend its service life.
2, adopt rolling friction to substitute original sliding friction, considerably reduce the frictional force between friction pair, thus make main cutting force be mainly used in cutting operation, instead of for overcome friction.
3, can be used in the processing of little helical pitch internal helical gear, due in the little internal helical gear process led, precession and the back-out of screw rod will be frequent, easily cause the wearing and tearing of wedge angle position, adopt ball wire rod mechanism to effectively reduce fretting wear, decrease the probability of wedge angle position infringement.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Fig. 1 is overall structure schematic diagram of the present utility model.
In figure: knife rest 1, ball screw axle 2, feed screw nut 3, ring flange 5, lathe main motion crank disc 6, ball-head tension rod 7, sphere cover assembly 8, angular contact bearing 9, worm screw 10, helical gearshaper cutter 11.
Detailed description of the invention
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further.
See Fig. 1, a kind of novel helical teeth gear shapping machine structure, it comprises lathe main motion crank disc 6, lathe main motion crank disc 6 is provided with ball-head tension rod 7, bulb and the sphere of ball-head tension rod 7 overlap assembly 8 and match and form bulb and be connected, sphere cover assembly 8 lower sleeve inside is provided with ball screw axle 2, ball screw axle 2 matches with feed screw nut 3, feed screw nut 3 is fixedly mounted on the inside of worm gear 4, described worm gear 4 forms Worm Wheel System with worm screw 10, and the inside of knife rest 1 is fixedly mounted on by ring flange 5, helical gearshaper cutter 11 is fixedly mounted on the end of ball screw axle 2.
Further, by pumping of the rotational movement ball-head tension rod 7 of lathe main motion crank disc 6, and then the up and down reciprocatingly operation of band movable knife rack 1 and helical gearshaper cutter 11, main cutting force is provided.
Further, by coordinating between worm screw 10 with worm gear 4, drive feed screw nut 3 to rotate, feed screw nut 3 drives ball screw axle 2 to rotate around its axial line, thus provides the screw in working angles.
Further, the top of described ball screw axle 2 is arranged on the inside of sphere cover assembly 8 by two angular contact bearings installed dorsad 9.The ability that ball screw axle 2 bears axial force can be improved by two angular contact bearings 9 installed dorsad.
The utility model device specific works principle and the course of work are:
1, lathe is rotated by lathe main motion crank disc 6, ball-head tension rod 7 is driven to rotate around sphere cover assembly 8, and then driving sphere cover assembly 8 to move back and forth, ball screw axle 2 rotates in feed screw nut 3 simultaneously, thus drives helical gearshaper cutter 10 to carry out spiral slotting campaign.
2, worm screw 10 drives worm gear 4, feed screw nut 3 rotates, and then drives ball screw axle 2, helical gearshaper cutter 11 to rotate around its center alignment fixed-direction, thus realizes slotting helical teeth compound motion.
