Abstract
The invention discloses the high-precision differential mechanisms using spherical pad, including shell, the both ends of shell are all provided with there are one bearing, differential axle there are one being set on each bearing, the end of each differential axle is all provided with that there are one axle shaft gears, each to be all provided between axle shaft gear and shell there are one elastic element, one end of elastic element is contacted with the seam allowance of shell, and the other end is in contact with corresponding axle shaft gear.The Novel differential gear can reach the big sideshake not only eliminated between planetary gear and axle shaft gear, but also prevent and stuck purpose occurs when gear drive;The increase of manufacturing cost, reasonable design of the present invention will not be caused to be suitble to promote the use of simultaneously.
Description
Technical field
The present invention relates to field of mechanical technique, and in particular to uses the high-precision differential mechanism of spherical pad.
Background technology
It needs 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 the part accuracy of manufacture, general assembly error, stand under load 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 the part accuracy of manufacture, general assembly error, stand under load 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 thing followed 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, vicious circle are thusly-formed, electronic again in turn with regard to even more serious
In the new energy vehicles transmission system such as vehicle, it is more obvious to beat the noise that tooth is brought.
Invention content
The present invention is above-mentioned in order to overcome the shortcomings of, provides a kind of big side both eliminated between planetary gear and axle shaft gear
Gap, and prevent and the stuck high-precision differential mechanism using spherical pad occurs when gear drive.
The present invention is achieved through the following technical solutions above-mentioned purpose:
Using the high-precision differential mechanism of spherical pad, including shell, the both ends of shell are all provided with that there are one bearing, each bearings
On set there are one differential axle, the end of each differential axle is all provided with there are one axle shaft gear, and shell is internally provided with 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
It does not set there are one planetary gear, two planetary gears are arranged in a planet axis, which is sequentially connected, and there are one masters to subtract
Fast tooth, the main reducing gear are parallel with planet axis;
Spherical pad is equipped between the planetary spherical surface and shell, the Internal Spherical Surface radius of a ball of shell is more than ball ring
0.5~1.0mm of piece outer ball diameter.
Specifically, being all provided between each axle shaft gear and shell, there are one flat pads.
Specifically, the shell is equipped with bolt.
Specifically, the planetary gear and axle shaft gear are bevel gear.
In the program, the differential casing Internal Spherical Surface radius of a ball is more than spherical pad 0.5~1.0mm of outer ball diameter, shell and ball
It is not to be bonded completely between the gasket of face, spherical pad plays the role of elastic element, after the completion of same assembly between bevel gear only
Reserved 0~the 0.05mm of sideshake that can form lubricating oil film.When initial assembly, it is ensured that two spherical pads have certain elasticity and become
Shape is worn due to the factors either longtime running such as manufacturing or assembling, and planetary gear and axle shaft gear sideshake become larger, two
Planetary gear moves inward reduction sideshake under the action of two spherical pad elastic forces respectively, conversely, there are stuck trend
When, two planetary gears further compress spherical pad, prevent stuck.
After in this way, occurred 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 will not cause manufacturing cost simultaneously reduces in conventional differential assembly, because adjusting axle shaft gear pad
The trouble that piece is brought.
The beneficial effects of the invention are as follows:Compared with the existing technology, the differential casing Internal Spherical Surface radius of a ball of the present invention is more than ball
Face gasket 0.5~1.0mm of outer ball diameter is not to be bonded completely between shell and spherical pad, and spherical pad plays elastic element
Effect, the only reserved 0~0.05mm of sideshake that can form lubricating oil film between bevel gear after the completion of same assembly;
Above technical scheme can reach the big sideshake not only eliminated between planetary gear and axle shaft gear, but also gear is prevented to pass
Stuck purpose occurs when dynamic;The increase of manufacturing cost will not be caused simultaneously.
