Description
Technical field
The utility model is specifically related to a kind of novel internal spherical cage universal joint.
Background technology
Rzeppa constant velocity joint is the critical component in automobile constant velocity universal joint drive spindle, Rzeppa constant velocity joint
Performance and quality life-span directly affect view of the people to automobile itself, universal with automobile, people make automobile
It is higher and higher with performance and the comfort requirement used.This Rzeppa constant velocity joint is internal spherical cage, and draw point can be in retainer
Interior carry out high speed rotation, then steel ball operated respectively inwards or outward, three-way axis outer wall occur rolling friction shorten,
Due under normal circumstances, needle roller inside three-way axis cannot good carry out uniform motion, cause cage frictional force strong, internal machine
Structure is unstable, generates a large amount of heat, working efficiency is reduced, therefore, it is necessary to be improved to internal spherical cage.
Utility model content
The purpose of this utility model is that a kind of novel internal spherical cage universal joint, to solve existing technical problem.
To achieve the above object, the utility model provides the following technical solutions：A kind of novel internal spherical cage universal joint, including clock
Shell, bell shell connect driving shaft by steel strap, and driving shaft right end extends to inside bell shell, are equipped on the outside of driving shaft right end
Retainer is equipped with loop between retainer and driving shaft, be equipped with three-way axis on the outside of retainer, and three-way axis is internally provided with needle roller, and three
To axis connection sliding sleeve, sliding sleeve connects cooling fin, three-dimensional axis connection constant speed instrument, and constant speed instrument is connected to the buzzing in outside by conducting wire
Device, buzzer are set on steel strap.
Further improvement of the utility model is：Protective shell is equipped on the outside of buzzer, protective shell is equipped with aperture.
Further improvement of the utility model is：Bell shell, driving shaft, retainer be all made of the forging of seamless steel and
At.
Compared with prior art, the utility model has the beneficial effects that：
The utility model is simple in structure, by constant speed run evenly of the constant speed instrument control needle roller inside three-way axis, improves
Stability and safety reduce frictional property by the use of sliding sleeve, reduce resistance, improve working efficiency, and good heat dissipation effect goes out
Even if now abnormal alarm, prolongs the service life.
Description of the drawings：

Specific implementation mode
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
It clearly and completely describes, it is clear that described embodiment is only the utility model a part of the embodiment, rather than whole realities
Apply example.Based on the embodiments of the present invention, those of ordinary skill in the art institute without making creative work
The every other embodiment obtained, shall fall within the protection scope of the present invention.
The utility model provides a kind of technical solution：
A kind of novel internal spherical cage universal joint, including bell shell 1, bell shell 1 connect driving shaft 3 by steel strap 2, preferably
It is 3 fixation of driving shaft, and can effectively obstructs phenomena such as junction falls ash, improves stability and precision, 3 right end of driving shaft
It extends to inside bell shell 1, retainer 4 is equipped on the outside of 3 right end of driving shaft, preferably protect driving shaft, improve security performance, clock
Shell 1, driving shaft 3, retainer 4 are all made of seamless steel and forge, and sound construction is with good stability, retainer 4
It is equipped with loop 5 between driving shaft 3, plays dottle pin effect, reduces friction, 4 outside of retainer is equipped with three-way axis 6, in three-way axis 6
Portion is equipped with needle roller 7, and three-way axis 6 connects sliding sleeve 10, and high lubricating effect reduces friction, reduces the generation of heat, effectively improved
The working efficiency of needle roller 7, sliding sleeve 10 connect cooling fin 11, and the heat that friction generates, which is effectively carried out bat, dissipates, and reduces internal stability,
Three-way axis 6 connects constant speed instrument 8, effectively carries out constant speed, improves stability, prolongs the service life, constant speed instrument 8 is connected to by conducting wire
The buzzer 9 in outside, 9 outside of buzzer are equipped with protective shell, and protective shell is equipped with aperture, preferably protects buzzer 9, occurs non-
When at the uniform velocity or being non-constant speed rotation, even if alarm, buzzer 9 is set on steel strap 2.
While there has been shown and described that the embodiments of the present invention, for the ordinary skill in the art,
It is appreciated that can these embodiments be carried out with a variety of variations in the case where not departing from the principles of the present invention and spirit, repaiied
Change, replace and modification, the scope of the utility model are defined by the appended claims and the equivalents thereof.
