Abstract
The utility model discloses a hypoid gear coupling. The hypoid gear coupling comprises a first gear sleeve, a second gear sleeve and a shaft liner used for connecting the first gear sleeve with the second gear sleeve, and the gear surfaces of the shaft liner are hypoid. Adopting the hypoid gear structure, the hypoid gear coupling is used for flexible drive, the deviation control capacity in the axial direction, the radial direction and the angular direction is strong, and the larger contact area between the two hypoid gear surfaces can effectively avoid the phenomenon that the local stress is centralized due to the annular deviation and the radial deviation, therefore the coupling is seldom worn out, and is dispensed with maintenance, and the service life of the coupling is prolonged.
Description
Technical field
The utility model relates to the coupling of hydraulic machinery, is specifically related to a kind of hyperboloid tooth shaft coupling.
Background technique
At present, the coupling in domestic hydraulic machinery field mostly is the straight-tooth coupling greatly, is having under the situation of installation deviation, and the straight-tooth contact surface easily produces the stress concentration phenomenon, the wearing and tearing of coupling have been accelerated, reduce the working life of coupling, and coupling on the market adopts all steel material to make, when operating with miscellaneous part, wearing and tearing mutually when unlubricated mutual motion need regular maintenance between the metal parts, and having influenced manufacturing efficiency has also increased cost of production.
The model utility content
Goal of the invention: the purpose of this utility model is in order to solve the deficiencies in the prior art, to provide a kind of not easy to wear, the hyperboloid tooth shaft coupling that need not keep in repair.
Technological scheme: in order to realize above purpose, a kind of hyperboloid tooth shaft coupling described in the utility model comprises the first tooth cover, second tooth cover and is connected first tooth cover and the axle sleeve of second tooth cover that the described axle sleeve flank of tooth is a hyperboloid.
Wherein, preferably, described first tooth cover is made for nylon material.
Wherein, preferably, described second tooth cover is made for nylon material.
Wherein, preferably, described first tooth cover and the second tooth cover are nylon material and make.
Wherein, preferably, described axle sleeve is that nylon material is made.
Beneficial effect: a kind of hyperboloid tooth shaft coupling that the utility model provides, owing to adopt the structure of hyperboloid tooth, be used for flexible drive, axially, radially very strong centering capacity is arranged with angle, bigger tooth surface of contact can be avoided the phenomenon of the stress raisers that cause because of angle and radial missing effectively, thereby coupling can not produce wearing and tearing substantially; Because first tooth cover or second tooth cover adopt nylon material to make, thereby the material fit of steel bearing and nylon tooth cover has guaranteed that the frictional force between the tooth surface of contact is very little in continuous transmission, thereby need not keep in repair, prolonged the operating life of self and adjacent component, damped vibration simultaneously, reduce noise, improved manufacturing efficiency and also reduced cost of production.

Fig. 5 is the structural representation of the utility model assembled state.
Embodiment
Below in conjunction with the drawings and specific embodiments, further illustrate the utility model.
As Fig. 1, Fig. 2, a kind of hyperboloid tooth shaft coupling shown in Figure 3, comprise first tooth cover, 1, second tooth cover 2 and the axle sleeve 3 that is connected first tooth cover, 1 and second tooth cover 2, described first tooth cover, 1 and second tooth cover 2 is nylon material and makes (also one of them adopts nylon material to make), described axle sleeve 3 is made (also can be nylon material makes) for steel material, and the flank of tooth 4 of described axle sleeve 3 is a hyperboloid 5.
The utility model adopts the double-joint type structure to need not bearings, can level and vertical installation, and easy for installation, need not any special assembling instrument.The utility model is used for flexible drive in use, axially, radially with angle very strong centering capacity is arranged, and can compensate very big installation deviation, and the stress of angle and radially installation deviation generation can be ignored simultaneously, and angular velocity cyclic fluctuation can not occur.First tooth cover, 1 and second tooth cover 2 is nylon material and makes, axle sleeve 3 is made for steel material, because the nylon composite materials smooth in appearance, hard, have a high thermal stability, and can anti-lubricant oil, corrosion such as fuel, hydraulic oil, solvent, and can not wear and tear even without lubricated and maintenance between smooth nylon and the steel yet, thereby the material fit of steel bearing and nylon tooth cover has guaranteed that the frictional force between the tooth surface of contact is very little in continuous transmission, thereby need not keep in repair, prolong the operating life of self and adjacent component; Damped vibration simultaneously reduces noise, has improved manufacturing efficiency and has also reduced cost of production.When axle sleeve 3 is also made for nylon material, reduced cost of production to a greater extent.
The foregoing description only is explanation technical conceive of the present utility model and characteristics, its objective is to allow to be familiar with these those skilled in the art and can to understand content of the present utility model and enforcement according to this, can not limit protection domain of the present utility model with this.All equivalents or modifications of having done according to the utility model spirit all should be encompassed within the protection domain of the present utility model.
