Abstract
The utility model discloses a spiral bevel gear for a drive axle of an automobile, which comprises an input bevel gear shaft and a driven gear, wherein the input bevel gear shaft and the driven gear are mutually meshed. Gear tooth profile of the input bevel gear shaft is of a spherical involute structure and shrinks with equal proportion from a large end of the bevel gear to a small end of the bevel gear. The spiral bevel gear for the drive axle of the automobile is high in accuracy, good in stable performance of meshing transmission, small in noise, capable of conveniently achieving mould forming in batches, simple in structure, ingenious in design, convenient, practical and suitable for widespread popularization and application.
Description
Technical field
The utility model relates to mechanical transmission component manufacturing technology field, is a kind of technological improvement that is used for the helical bevel gear of automobile drive axle specifically.
Background technique
In gear transmission part, very important kind of drive of awl (umbrella) tooth transmission; In the existing technology; A kind of spiral arc bevel gear is arranged; It is by the Gleason company design of the U.S. the earliest and makes; The gear of this standard becomes the main product of spiral awl tooth, and uses till today always, and its structural major character is that the tooth trace helical pitch of this helical bevel gear is the circular arc line of conical surface.Its deficiency is: such gear is not suitable for adopting the mould manufacturing, because its tooth trace is a circular arc line, deviates from the former process at product; The phenomenon that has interference takes place; Do not meet formed in mould making principle, and the accuracy of gear is not high, the engagement driving stationarity is general.Thereby design a kind of compact structure, and being skillfully constructed, the accuracy of gear is high, and the engagement driving stationary performance is good, and the convenient formed in mould helical bevel gear of batch of realizing is the utility model design place.
Summary of the invention
The purpose of the utility model is the shortcoming that overcomes above-mentioned existing technology, and a kind of compact structure is provided, and is skillfully constructed, and the accuracy of gear is high, and the engagement driving stationary performance is good, and the convenient formed in mould helical bevel gear in batches of realizing.
The utility model can be realized through following technological scheme:
The utility model discloses a kind of helical bevel gear that is used for automobile drive axle; This helical bevel gear comprises input bevel gear shaft and follower; Input bevel gear shaft and follower are meshing with each other; The gear tooth profile of described input bevel gear shaft is spherical involute shape structure, and input bevel gear shaft gear tooth profile shrinks to cone gear small end equal proportion from the big end of cone gear.
It is long that the utility model and like product have precision height, life-span, the characteristics that the engagement driving stationarity is good, noise is little.The accuracy of gear is stable to reach 7 class precisions, and some projects are superior to 7 class precisions, and like gear ring circular runout≤member 0.036, the gear vibration noise is controlled at 1200 rev/mins of time≤72 decibel, reaches the excellent level of the domestic same industry (greater than 600,000 times) fatigue life; Gear once matches up-to-standard rate and reaches more than 99%.Be highly suitable for the application of driving rear axle gears such as miniature commercial car, pickup automobile.
The utility model compared with prior art has following advantage:
The utility model adopts the gear tooth profile of input bevel gear shaft to be spherical involute shape structure, and input bevel gear shaft gear tooth profile shrinks to cone gear small end equal proportion from the big end of cone gear, and the accuracy of gear is high; The engagement driving stationary performance is good, and noise is little, and the convenient mould-forming in batches of realizing; It is simple in structure; Be skillfully constructed, very convenient and practical, be fit to generally promote the use of.
Description of drawings
Accompanying drawing 1 is the utility model structural representation;
Accompanying drawing 2 is the utility model input bevel gear shaft structural representation.
Embodiment
To combine Figure of description to come the utility model is further described below:
Shown in accompanying drawing 1 and accompanying drawing 2; Present embodiment discloses a kind of helical bevel gear that is used for automobile drive axle; This helical bevel gear comprises input bevel gear shaft 1 and follower 2; Input bevel gear shaft 1 is meshing with each other with follower 2, and the gear tooth profile of described input bevel gear shaft is spherical involute shape structure, and input bevel gear shaft gear tooth profile shrinks to cone gear small end equal proportion from the big end of cone gear.
It is long that the utility model and like product have precision height, life-span, the characteristics that the engagement driving stationarity is good, noise is little.The accuracy of gear is stable to reach 7 class precisions, and some projects are superior to 7 class precisions, and like gear ring circular runout≤member 0.036, the gear vibration noise is controlled at 1200 rev/mins of time≤72 decibel, reaches the excellent level of the domestic same industry (greater than 600,000 times) fatigue life; Gear once matches up-to-standard rate and reaches more than 99%.Be highly suitable for the application of driving rear axle gears such as miniature commercial car, pickup automobile.
The above is merely the preferred embodiment of the utility model, is not the utility model is done any pro forma restriction; But the those of ordinary skill of all industry is all implemented the utility model with the above shown in the by specification accompanying drawing swimmingly; But all professional and technical personnel of being familiar with the above technology contents that is disclosed capable of using and a little change of making, modify the equivalent variations with differentiation in not breaking away from the utility model technological scheme scope, be the equivalent embodiment of the utility model; Simultaneously, all essence technology according to the utility model to the change of any equivalent variations that above embodiment did, modify with differentiation etc., all still belong within the protection domain of technological scheme of the utility model.
