Description
Technical field
The utility model relates to field of mechanical technique, and in particular to a kind of high-precision differential mechanism using elastic element.
Background technique
Need to reserve a certain amount of sideshake between the planetary gear and axle shaft gear of existing differential for vehicles, this is mainly examined
Consider the factors such as part manufacturing precision, general assembly error, loaded elastic deformation, thermal deformation and flank of tooth film lubrication, with
Occur stuck when preventing gear from rotating, causes transmission failure that accident even occurs, in general, in factors above, except for shape
It needs to be arranged except a small amount of sideshake at oil film, considers part manufacturing precision, general assembly error, loaded elastic deformation, thermal deformation
Factor and reserved sideshake is unfavorable to transmission properties.Generally reserved sideshake is 0.05~0.25mm, so big side
Gap consequent side effect be generated when the decline and engagement of gear-driven accuracy beat tooth phenomenon, and as part is ground
The aggravation of damage, this phenomenon exacerbate the abrasion of part again in turn, vicious circle are thusly-formed, electronic with regard to even more serious
In the new energy vehicles transmission system such as vehicle, it is more obvious to beat tooth bring noise.
Utility model content
The utility model is above-mentioned in order to overcome the shortcomings of, provide it is a kind of both eliminated it is big between planetary gear and axle shaft gear
Sideshake, and prevent and the stuck high-precision differential mechanism using elastic element occurs when gear drive.
The utility model achieves the above object through the following technical schemes:
Using the high-precision differential mechanism of elastic element, including shell, the both ends of shell are equipped with a bearing, each bearing
It is equipped with a differential axle, the end of each differential axle is equipped with an axle shaft gear, and the inside of shell sets that there are two mutually
The perpendicular through-hole in cross distribution, two axle shaft gears are located in one of the both ends of through-hole, the both ends point of another through-hole
Not She You a planetary gear, two planetary gears are arranged in a planet axis, which is sequentially connected with a master and subtracts
Fast tooth, the main reducing gear are parallel with planet axis；
An elastic element is equipped between each axle shaft gear and shell, one end of elastic element and the seam allowance of shell connect
Touching, the other end are in contact with corresponding axle shaft gear.
Specifically, the planetary gear and axle shaft gear are bevel gear.
Specifically, the elastic element is normal spiral spring or butterfly spring.
Specifically, being equipped with spherical pad between the planetary gear spherical surface and shell.
Specifically, the shell is equipped with bolt.
In the program, the flat pad generallyd use is eliminated at the position that two axle shaft gears are in contact with shell, is changed
At elastic element, when assembly, need to guarantee that spring is in compressive state, only reserve be capable of forming between bevel gear after the assembly is completed
0~0.05mm of sideshake of lubricating oil film is ground in engaged transmission due to the factors either longtime running such as manufacturing or assembling
There is sideshake in damage, planetary gear and axle shaft gear, two axle shaft gears anterior displacement under spring force, to reduce sideshake；
There are when stuck trend, two axle shaft gear rearward displacements are prevented stuck with compressed spring.
After in this way, generation when not only having eliminated the big sideshake between planetary gear and axle shaft gear, but also having prevented gear drive
Stuck purpose；The increase that not will cause manufacturing cost simultaneously reduces in conventional differential assembly, because adjusting axle shaft gear pad
Piece bring trouble.
The beneficial effects of the utility model are: this is used in the high-precision differential mechanism of elastic element, in two axle shaft gears
The position being in contact with shell eliminates the gasket generallyd use, has been changed to elastic element, after the assembly is completed between bevel gear only
Reserved 0~the 0.05mm of sideshake for being capable of forming lubricating oil film；Above technical scheme, which can reach, both eliminates planetary gear and half axle gear
Big sideshake between wheel, and prevent and stuck purpose occurs when gear drive；The increase of manufacturing cost is not will cause simultaneously.
