It belongs to the universal joint shaft of the mill frame, mainly to solve the existing technical problems such as short service life of the joint shaft.
The main points of its technical program: including the cross universal joint shaft body and the bearing gland which is solidly connected with the convex round fork, characterized by: a groove is set on the convex round fork, and a bolt hole corresponding to the screw hole on the bearing gland is set on the outer side of the groove, and the bearing gland is solidly connected with the convex round fork through the bolts.
It ensures its sufficient strength and does not affect the use of the entire cross universal joint shaft, the use of standard parts fastening bolt connection, more economical and practical.
Experimental evidence in accordance with this method of transformation of the universal joint shaft, the service life of one year, than the original life extension of 2 times, the amount of maintenance is greatly reduced, the mill equipment start rate increased significantly, resulting in good economic and social benefits.
It can be popularized and applied to various types of rolling mills and other poor working conditions under the mechanical transmission.
