Product Description


The detail description of
Universal joint:


Material:
   Normally we are using 20Cr or 20CrMnTi gear steel, as
chinese standarded


alloy steel for the cross
spider of our universal joint cross assembly and the


glove bearing is also based on
such material. Also we can make the u-joint as


you requested material when the
quantity is acceptable for production lot. For


the needle roller, the material
will be GCr15 bearing steel. High-quality materials


are used for our accessarries
such snap ring, NBR seal rings, straight or


jointed hydraulic grease
nipples, and general purpose lithium base grease for


automobile.


 Application:


     A power transmission universal joint cross assembly is widely used
in automobile types including: middile and high end salon, off-road vehicles,
most of the trucks, agriculture machinery, mine and heavy-duty machine,
specifical purpose vehicles.


 


 


Structure:
     A universal joint has four needle roller bearings that
provide the strength and life which is most important and both the axes of the
spider are inserted into two yokes. In the
bearing, a seal is located to prevent dust, water, etc.from ingress and to
prevent grease egress. For heavy duty vehicles with
high torque transmission, such as large size vehicles and various industrial
machine vehicles, a wing type (3 kinds: block, wing, delta) is used. Bolt-fastening mechanism and key-way are incorporated to the
bearing and a precise circle is on its back. By receiving the torque
through the key-way, even if a bolt is loosely tightened, the shearing stress
does not  apply to
the bolt.


 


The advantage of Universal joint:
 A universal joint is fitted between the
driveshaft and the differential axle to transmit power through the axis of
rotation. Perfectly smooth rotation is required, in order to handle the
constantly changing angles of the rear axle caused by the vertical movement of
uneven surfaces transmitted through the suspension system. In other words, a
universal joint efficiently transmits power through both fixed and fluctuating
angles. Moreover, since the universal joint is lightweight and compact with
superior durability, it has proved to be a safe and positive product for power
transfer in Automotive and Industrial applications. In recent years, we have
been working to develop and produce the press type bearing which is aimed at
improvement in intensity and durability and reduces cost further.
