Abstract
The utility model discloses a combined gear structure which comprises an outer gear ring and an inner shaft sleeve which are coaxial, wherein a plurality of grooves are circumferentially distributed in a part of contact between the outer gear ring and the inner shaft sleeve; pressure springs and guide pins penetrating through the pressure springs are arranged in the grooves; the two ends of each pressure spring are propped against the two sides of each groove respectively; a flat gasket and a shaft sleeve flange are arranged on the two sides of the pressure spring in the axial direction of the outer gear ring and the inner shaft sleeve respectively; a disc spring is arranged between each flat gasket and the side surface of the pressure spring. According to the combined gear structure, the radial impact force is absorbed by compressing the pressure springs mounted in the grooves between the outer gear ring and the inner shaft sleeve, so that the impact force between gears is reduced during working of the combined gear; the two sides of the pressure spring are limited through the flat gasket and each shaft sleeve flange on the inner shaft sleeve; the disc springs have a buffer effect on the axial displacement of the outer gear ring, so that the integral buffer effect of the gear structure can be effectively enhanced, the purpose of effectively reducing the noise can be achieved, and the service life of the gears can be prolonged. The combined gear structure is used in the field of gear structures.
Description
Technical field
The utility model relates to gear structure field, particularly relates to a kind of built up gear structure.
Background technique
Built up gear is conventionally arranged on trunnion shaft and drives trunnion shaft to rotate the first order reciprocating inertia force of balanced engine, thereby reduces the vibration of motor.
Existing built up gear passes through circumferentially increasing several damping springs conventionally, then inner sleeve and outer shroud are riveted to as a whole formation, or relies on the end face of gear to carry out axially locating.This type of built up gear is when High Rotation Speed, the Internal and external cycle of engagement can have the effect of a buffering, but gear shaft is to without buffer function, and the technique that inner sleeve and outer shroud are riveted is comparatively complicated, and its axial displacement cannot compensate in the process that runs up, be easy to produce noise.
Model utility content
For addressing the above problem, the utility model provides a kind of built up gear structure that can effectively increase axial buffer effect.
The utility model solves the technological scheme that its technical problem adopts:
A kind of built up gear structure, the outer tooth ring and the internal axle sleeve that comprise coaxial setting, along the circumferential contacting point at outer tooth ring and internal axle sleeve, be distributed with some grooves, in each groove, be equipped with stage clip and through the guide finger of stage clip, the two ends of stage clip lean respectively in groove both sides, along the axial of outer tooth ring and internal axle sleeve, in the both sides of stage clip, be respectively equipped with plain washer and axle sleeve flange, between the side of plain washer and stage clip, be provided with belleville spring.
Be further used as the improvement of technical solutions of the utility model, axle sleeve flange protrudes from the end face of outer tooth ring, and the inner side surface of axle sleeve flange is close to the end face of outer tooth ring.
Be further used as the improvement of technical solutions of the utility model, the external diameter of plain washer is less than the internal diameter of outer tooth ring.
Be further used as the improvement of technical solutions of the utility model, outer tooth ring and internal axle sleeve Spielpassung.
Be further used as the improvement of technical solutions of the utility model, each groove is rectangle groove, and the length of each guide finger is less than the length of groove.
The beneficial effects of the utility model: this built up gear structure compresses to absorb impact force radially by being arranged on the stage clip in some grooves between outer tooth ring and internal axle sleeve, thereby while making built up gear work, impact force between gear is eased, this gear structure carries out spacing by the axle sleeve flange on plain washer and internal axle sleeve to the both sides of stage clip simultaneously, belleville spring plays buffer function to the axial displacement of outer tooth ring, thereby can effectively strengthen the integrated buffer effect of gear structure, reach the object of effective noise reduction, extend the working life of gear.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Fig. 1 is that the utility model embodiment uses view;
Fig. 2 is the utility model embodiment circle inner structure detailed maps in Fig. 1;
Fig. 3 is the utility model embodiment plan view.
Embodiment
With reference to Fig. 1～Fig. 3, the utility model is a kind of built up gear structure, the outer tooth ring 1 and the internal axle sleeve 2 that comprise coaxial setting, along the circumferential contacting point at outer tooth ring 1 and internal axle sleeve 2, be distributed with some grooves 3, in each groove 3, be equipped with stage clip 5 and through the guide finger 4 of stage clip 5, the two ends of stage clip 5 lean respectively in groove 3 both sides, along the axial of outer tooth ring 1 and internal axle sleeve 2, are respectively equipped with plain washer 6 and axle sleeve flange 21 in the both sides of stage clip 5, between the side of plain washer 6 and stage clip 5, are provided with belleville spring 7.
This built up gear structure absorbs impact force radially by stage clip 5 compressions that are arranged in 2 some grooves 3 of outer tooth ring 1 and internal axle sleeve, thereby while making built up gear work, impact force between gear is eased, this gear structure is undertaken spacing by the both sides of the 21 pairs of stage clips 5 of axle sleeve flange on plain washer 6 and internal axle sleeve 2 simultaneously, buffer function is played in the axial displacement of 7 pairs of outer tooth rings 1 of belleville spring, thereby can effectively strengthen the integrated buffer effect of gear structure, reach the object of effective noise reduction, extend the working life of gear.
As the utility model preferred embodiment, axle sleeve flange 21 protrudes from the end face of outer tooth ring 1, and the inner side surface of axle sleeve flange 21 is close to the end face of outer tooth ring 1,1 of internal axle sleeve 2 and outer tooth ring is reached closely and coordinate.
As the utility model preferred embodiment, the external diameter of plain washer 6 is less than the internal diameter of outer tooth ring 1.
Plain washer 6 and internal axle sleeve 2 are coaxially arranged on running shaft, and the inner side end of the end face of plain washer 6 and internal axle sleeve 2 is close to, and 1 of plain washer 6 and outer tooth ring leave a small amount of gap can be convenient to add lubricant oil in gear structure.
As the utility model preferred embodiment, outer tooth ring 1 and internal axle sleeve 2 Spielpassung.
As the utility model preferred embodiment, each groove 3 is rectangle groove, and the length of each guide finger 4 is less than the length of groove 3.
In this gear rotary course; running shaft drives internal axle sleeve 2 to be rotated; frictional force due to 1 of internal axle sleeve 2 and outer tooth ring; and the pressure of stage clip 5; can drive outer tooth ring 1 motion; thereby 2 of outer tooth ring 1 and internal axle sleeves contacts at a high speed the impact force producing and can pass through outer tooth ring 1 and be passed to stage clip 5 and be eased, and axle sleeve flange 21 is set in stage clip both sides and belleville spring 7 can carry out buffer protection to side, stage clip both sides, thereby further extend the working life of gear structure integral body.
Certainly, the invention is not limited to above-mentioned mode of execution, those of ordinary skill in the art also can make equivalent variations or replacement under the prerequisite without prejudice to the utility model spirit, and the modification that these are equal to or replacement are all included in the application's claim limited range.
