The beneficial effects of the utility model are that: adopt the relative pivoted configuration mode of a bevel gear and the 2nd bevel gear suit and ability with original monolithic structure's bevel gear, set up the pressure spring simultaneously between first and second bevel gear, thereby make the relative rotation of first and second bevel gear realize eliminating backlash through the tension of pressure spring to realize backlash automatic compensation's mesh.
Description
Technical field
The utility model relates to a kind of cone gear circumference spring side set setting device, belongs to field of machine tool equipment.
Background technology
Geartransmission is widely used in Machine Tool design is with manufacturing, along with lathe is to the requirements at the higher level of precision, rigidity, speed and energy consumption, to machine tool gears transmission rig, especially the gear drive of machine tool chief axis it is also proposed higher requirement, wherein one is requirement geartransmission gapless, namely gear drive possesses the gap function that disappears, and to meet the service requirements of precision drive and high-performance cutter, this just needs to carry out the design of geartransmission anti-backlash mechanism.
The gap method that disappears conventional at present is for eccentric axle sleeve adjusting method, it adjusts the width between centers between intermeshing two gears by eccentric rotation axis cover, thus reach the object eliminating tooth side clearance, but this kind of method sideshake can not compensate automatically at two gears after adjusting, so the transmission rig that accuracy requirement is high still can not be met requirement by kind method.
Practical novel content
The utility model is intended to provide a kind of can be eliminated tooth side clearance and can realize the cone gear circumference spring side set setting device of compensation automatically.
Cone gear circumference spring side set setting device in this scheme, comprise the first cone gear and the 2nd cone gear, first cone gear is provided with projection, 2nd cone gear empty set is in projection, 2nd cone gear can around own axis but shaftless to degree of freedom, first cone gear circumference is evenly equipped with at least two circular grooves, 2nd cone gear circumference is evenly equipped with the convex pawl identical with circular groove quantity, convex pawl can stretch into come and go in circular groove and along circular groove and move, it is provided with stage clip between convex pawl and circular groove, stage clip one end and convex pawl offset, the stage clip the other end and circular groove offset, stage clip is in by compressed state, stage clip can be produced when compressing and compression direction opposite effect power.
The principle of work of the cone gear circumference spring side set setting device in this scheme is: when two cone gears cooperations carry out transmission, one of them wide cone gear adopts ordinary construction, another cone gear adopts the structure of the first cone gear and plug tap gear set in this scheme, when carrying out cone gear and assemble, the convex pawl of the 2nd cone gear is stretched in the upper corresponding circular groove of the first cone gear, now it is positioned between convex pawl and circular groove by the stage clip of compressed state by being in, owing to the tension force contrary with compression direction will be produced when stage clip is compressed, 2nd cone gear can around own axis simultaneously, therefore under the effect of stage clip tension force, convex pawl is promoted to move along circular groove, namely the 2nd cone gear is around own axis, until the first cone gear offsets with wide cone gear teeth groove side, 2nd cone gear offsets with wide another side of cone gear teeth groove, now under the restriction of wide cone gear teeth groove, stage clip compression degree remains unchanged, if in working process, there is tooth side clearance in first cone gear or the 2nd cone gear and wide gear teeth groove, under the effect of stage clip tension force, 2nd cone gear is around own axis, until eliminating tooth side clearance, therefore the automatic compensation of tooth side clearance can be realized.
The useful effect of the cone gear circumference spring side set setting device in this scheme is: the cone gear of original one-piece construction is adopted the first cone gear and plug tap gear set and can structure mode in relative rotation, stage clip is set between the first and second cone gears simultaneously, make the first and second cone gears relatively rotate thus realize eliminating tooth side clearance by the tension force of stage clip, and realize the object that tooth side clearance compensates automatically.
Further, in order to make the 2nd cone gear shaftless to degree of freedom, being connected with axle by the first cone gear, axle is provided with the baffle plate for the 2nd cone gear carries out axial limiting, and plug tap face of gear is put down together to the end face of baffle plate and projection.
Further, in order to the position relation making the first cone gear and the 2nd cone gear can keep correct when mounted, the first cone gear also has stop screw when installing location for the 2nd cone gear.
Further, in order to make the uniform force of whole device, circular groove is 3.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
Fig. 2 is the sectional view of the utility model embodiment G-G.
Embodiment
Below by embodiment, the utility model is described in further detail:
Reference numeral in Figure of description comprises: the first cone gear 1, the 2nd cone gear 2, wide gear 3, stage clip 4, stop screw 5, convex pawl 6, circular groove 7, axle 8.
Embodiment is substantially as shown in Figures 1 and 2: cone gear circumference spring side set setting device, comprises the first cone gear 1, the 2nd cone gear 2, wide gear 3, stage clip 4, stop screw 5, convex pawl 6, circular groove 7 and axle 8.
Open-celled structure centered by first cone gear 1, interior hole has keyway, this keyway is for installing flat key, first cone gear 1 is arranged on axle 8, first cone gear 1 has a projection, also being evenly distributed with three circular grooves 7 in the first cone gear 1 circumference, have a threaded hole in the side of the first cone gear 1, threaded hole is for installing stop screw 5 herein.
In 2nd cone gear 2, hole empty set is in the projection of the first cone gear 1, and the 2nd cone gear 2 end face and protruding end face, at axle 8 projection place, end is provided with a baffle plate, baffle plate and the 2nd cone gear 2 offset, thus the axial motion of the 2nd cone gear 2 is limited, on the 2nd cone gear 2, circumference is also evenly distributed with three convex pawls, 6, three convex pawls 6 and can stretch into respectively in three circular grooves 7, and convex pawl 6 can come and go motion in circular groove 7.
Stage clip 4 all it is furnished with between each convex pawl 6 and circular groove 7, this stage clip 4 remains compressed state, first cone gear 1 and the 2nd cone gear 2 all gear grooved with wide gear 3 coordinate, when there is tooth side clearance when between the first cone gear 1, the 2nd cone gear 2 and wide gear 3 teeth groove, convex pawl 6 is made to move in circular groove 7 under the effect of stage clip 4 tension force, 2nd cone gear 2 is around own axis, until tooth side clearance is eliminated.
