Description
Technical field
The utility model relates to a kind of transmission device, a kind of specifically transmission device that is used on the roller cold-upsetting machine.
Background technique
At present, the transmission device that is used on the roller cold-upsetting machine generally has driving gear and five shapes wheel to be used, five shapes wheel is arranged in the driving gear aperture, live axle passes motion to driving gear through five shapes wheel, thereby the driving miscellaneous part, this kind structural disadvantages is as follows: one, conventional driving gear does not generally have inner lining structure, because it is structure as a whole, its end face is provided with tooth engaged, so the material of this gear requirement hardness can not be too high, generally adopts Bearing Steel, yet, in this bore footpath, be provided with the five shapes wheel that drives its running, transmission shaft cooperates with five shapes wheel by key, therefore drives this gear operation, in the operation process, owing to the reason that is subjected to load, wearing and tearing are very fast, and change and this gear integral body need be changed, therefore, engineering time is long, and waste material is serious.Two, five shapes wheel operated by rotary motion and transmission shaft cooperate by key, drive driving gear, because the angle between the conventional five shapes wheel rib tooth is 90 degree, between any two rib teeth, be provided with rolling element, find through long-time the use, five shapes wheel effect in transmission process of this kind structure is relatively poor, and wearing and tearing are very fast.
The model utility content
The purpose of this utility model is to be the deficiency that solves the problems of the technologies described above, and a kind of transmission device that is used on the roller cold-upsetting machine is provided, and it is simple in structure, and transmission performance is good, and is wear-resistant, and prolonged more than the twice working life.
The utility model is the deficiency that solves the problems of the technologies described above, the technological scheme that is adopted is: a kind of transmission device that is used on the roller cold-upsetting machine, by driving gear, the five shapes wheel and the rolling element that are arranged on the driving gear endoporus constitute, described driving gear is the gear mass of annular, on gear mass one end face, be provided with tooth engaged, be provided with on the inner peripheral surface of gear mass annular on fixed cover and following fixed cover, described five shapes wheel is the circle body of annular, evenly be provided with five rib teeth on the circle body outer peripheral surface, the outer diametric plane of rib tooth is a circular arc, and the angle between per two rib teeth is 75 degree.
Be provided with jump ring in the groove between tooth engaged and last fixed cover.
Described aperture of going up the aperture of fixed cover greater than following fixed cover.
Described circle body both ends of the surface up and down is provided with setting sleeve.
One end face of described rib tooth is provided with spring eye.
The beneficial effects of the utility model are:
1, this apparatus structure is simple, and good braking effect can be used as overrunning clutch and uses on the roller cold-upsetting machine, and wear-resistant, and working life is longer.
2, this driving gear first within it the aperture be provided with two fixed covers, it is convenient to change, when the wearing and tearing of internal fixation cover are serious, can wait and change interior cover just, do not need whole driving gear is all changed, save material, and be provided with the internal fixation cover, because fixed cover and original gear body unlike material, it has higher intensity, wear-resistant, as to have improved this driving gear greatly working life.The five shapes wheel that is provided with in it is adjusted into 75 degree through test of many times with the angle between two rib teeth, five shapes wheel better effects if in transmission process of this kind structure, and braking is fast, and it is little to wear and tear.
3, because it is 90 degree that conventional five shapes are taken turns the angle of any two rib teeth, be prone to skidding between five shapes wheel that cooperates with the transmission axle key in the transmission process and the driving gear, skid and caused main contact surface abrasion fast, and transmission performance is very poor, therefore, make that reject rate improves in the work of roller cold-upsetting machine, through experimental results show that: the angle that five shapes are taken turns any two rib teeth is adjusted into 75 when spending, be arranged in the transmission process that rolling element better contacts with the driving gear inner peripheral surface between the five shapes wheels rib bottom angle, skidding no longer takes place, transmission performance improves greatly, and also improve more than 2 times working life.

Embodiment
As shown in figures 1 and 3, a kind of transmission device that is used on the roller cold-upsetting machine, constitute by driving gear 1, the five shapes wheel 2 and the rolling element 3 that are arranged on driving gear 1 endoporus, rolling element 3 is arranged on the five shapes wheel 2 in the space between any two rib teeth 5, five shapes wheel 2 passes through and the transmission axle key cooperates, thereby passes motion to driving gear 1.
As shown in Figures 2 and 3, described five shapes wheel is provided with the circle body 4 of an annular, evenly is provided with five rib teeth 5 on circle body 4 outer peripheral surfaces, and the outer diametric plane of rib tooth 5 is a circular arc, and the angle between per two rib teeth is 75 degree.
Described circle body about in the of 4 both ends of the surface be provided with setting sleeve 6, when cooperating, be provided with bearing between the external peripheral surface of this setting sleeve 6 and the inner peripheral surface of driving gear with driving gear.
One end face of described rib tooth 5 is provided with spring eye 7, when cooperating with driving gear, between the rib tooth 5 of any two 75 degree of being separated by, be provided with rolling element 3, being provided with spring in the spring eye 7 exerts pressure to rolling element, when live axle stops the rotation, the five shapes wheel that cooperates with the driving axle key stops the rotation simultaneously, at this moment, on the driving gear sense of rotation, the rolling element that is provided with between five shapes wheel and the rib tooth has very strong surface friction drag to driving gear, driving gear stops rapidly, and therefore, this five shapes wheel can be used as overrunning clutch when cooperating with driving gear and uses.
As shown in Figure 4 and Figure 5, described driving gear is provided with the gear mass 8 of an annular, be provided with tooth engaged 9 in the upper-end surface of gear mass 8, be provided with on the inner peripheral surface of gear mass 8 annular on fixed cover 10 and following fixed cover 11, described aperture of going up the aperture of fixed cover 10 greater than following fixed cover 11, last fixed cover 10 and the five shapes wheel 2 that is arranged in the driving gear endoporus contact, therefore the inner peripheral surface of going up fixed cover is a rubbing surface, the upper-end surface of following fixed cover is a frictional contact surface, thereby increasing by two very high frictional contact surfaces of hardness, better to have solved conventional driving gear easy to wear, be difficult for difficult problems such as replacing.
The utility model is provided with jump ring 12 in the groove between tooth engaged 9 and last fixed cover 10, and the purpose that jump ring is set herein is more stable in order to guarantee that fixed cover cooperates with gear mass.
This driving gear increases by two fixed covers, and two fixed covers all needed to overflow to cooperate and were pressed into the gear mass endoporus, so that assurance transmission accuracy, the material of two fixed covers is die steel, intensity is higher, and is not easy to wear, therefore makes the life-span of this driving gear improve greatly, and having increased by two dismountable fixed covers, maintenance, replacing are conveniently.
