Embodiment
The preferred embodiment of the present invention is described in detail below in conjunction with the accompanying drawings, so that advantages and features of the invention energy
It is easier to be readily appreciated by one skilled in the art, so as to make a clearer definition of the protection scope of the present invention.
Referring to Fig. 2 to Fig. 5, a kind of tension pulley, including tensioning wheel 1, preceding dustproof cover 2, rear dust cover 3, sealing ring 4,
Bearing 5 and connection bolt 6.
Preceding dustproof cover 2 is located at the front end of tensioning wheel 1, and rear dust cover 3 is located at the rear end of tensioning wheel 1, and bearing 5 is inserted into tensioning wheel
1, connection bolt 6 is inserted into the inner wall of bearing 5.Sealing ring 4 is between connection bolt 6 and bearing 5.
1 circular ring shape of tensioning wheel is shelly-shaped, and center is through hole.1 surface of tensioning wheel is coated with coating by ability cathode electrophoresis.Tensioning wheel 1
Through-hole wall 1a be smooth surface.The section of tensioning wheel 1 is U-shaped.The outer wall of through-hole wall 1a and bearing 5 is interference fit.Bearing 5 is installed
When, bearing 5 is pressed into the through hole of tensioning wheel 1 by oil pressure interference fit.The interface of tensioning wheel 1 is U-shaped, can be with referring to Fig. 3
It is processed by disposal molding, after being polished to the through-hole wall 1a of tensioning wheel 1, is pressed directly into bearing 5.It is greatly reduced
