With the new structure power transmission shaft of long lifespan.
The purpose of this utility model can be realized by following technical proposal：A kind of new structure power transmission shaft, including mandrel
And it is respectively arranged at the clutch can and cylinder outer race at mandrel both ends, it is characterised in that inner race, institute are provided with the clutch can
Retainer is provided with the inner race periphery stated, is provided with ball between described retainer and inner race, the ball it is interior
End face is in rolling contact with retainer, and its outer face is in contact with clutch can inwall, and the cylinder outer race is internally provided with plane axis
Cover, be provided with parallel shelf on described flat bush, described parallel shelf one end is resisted against on the end face inside cylinder outer race, described
Several are circumferentially evenly distributed with parallel shelf and slides ball, described cunning ball outer face keeps sliding contact with cylinder outer race inner face,
Its inner face is engaged with flat bush, and one end of the mandrel is penetrated in clutch can be fixedly connected with inner race, and its other end is stretched
Enter the inside of cylinder outer race, be fixedly connected with flat bush, the mandrel and flat bush mating connection cause power transmission shaft compression,
Range of stretch is 755 millimeters to 802 millimeters.
In a kind of above-mentioned new structure power transmission shaft, it is provided between described clutch can, cylinder outer race and mandrel anti-
Dust hood, described dust cover one end are arranged at the outer face edge of clutch can, cylinder outer race, and its other end card sets and in mandrel
On.The setting of dust cover helps prevent introduced contaminants to enter power transmission shaft and clutch can, the junction of cylinder outer race, and raising goes slick
Property.
In a kind of above-mentioned new structure power transmission shaft, the outer end Yan Chu inside described cylinder outer race is provided with to be worn for mandrel
The end cover crossed, described end cover using can the fluorubber material of deformation be made.End cover is manufactured using fluorubber,
Can deformability is strong, good airproof performance, the secondary ability for improving protection cylinder outer race and entering impurity.
In a kind of above-mentioned new structure power transmission shaft, the chuck of circumferential projection is provided with described mandrel, it is described
The side that chuck is used to help dust cover is fixed on mandrel.When preventing that power transmission shaft from working, dust cover produces cunning under force
Move, prolonged sliding, which easily causes, to come off.
In a kind of above-mentioned new structure power transmission shaft, installation opening one end of described flat bush offers chamfering.Side
Just the Fast Installation of mandrel, operating efficiency is improved.
Compared with prior art, this new structure power transmission shaft is improved traditional tubular shell structure, is made after improvement
It is bigger to obtain the scope of power transmission shaft compression and tension, simultaneously because driving torque is changed so that transmission is more stable, has
The advantages of ensuring smooth transmission, long service life.
