The utility model content

Technical problem to be solved in the utility model is to provide a kind of modified form friction aligning carrier roller at the existing friction existing deficiency of aligning carrier roller.

Technical problem to be solved in the utility model can be achieved through the following technical solutions:

A kind of modified form friction aligning carrier roller comprises:

One;

One is installed in roll body on the axle by first back-up ring, clutch shaft bearing, in described first back-up ring, the both sides of clutch shaft bearing are separately installed with first seal ring assembly and second seal ring assembly, wherein second seal ring assembly is limited in first back-up ring by seal disc, the second back-up ring assembly, baffle plate; Described axle has at least one section to expose outside the described baffle plate;

One exposes the friction wheel on a section outside the described baffle plate by axle sleeve, the 3rd poted assemblies, second bearing installation at described axle, and described second bearing is installed in the 3rd back-up ring component limitations on the friction wheel in friction wheel by one;

Be enclosed within described axle and expose spring fixture block, spring, friction shoe and the end cap on a section outside the described baffle plate, described end cap is connected with the end face of described friction wheel by fastener, and described friction shoe, spring and spring fixture block be limited between end cap and the 3rd back-up ring assembly, wherein friction shoe and end cap wipe contact, described spring is limited between described spring fixture block and the friction shoe, is provided with the 4th poted assemblies between described end cap and described axle;

It is characterized in that it is the coiling of 3.2mm spring wire that described spring adopts diameter, described spring external diameter is 42mm, and length is 60mm.

To the rub friction wheel in-to-in spring size φ 42*4*75 of aligning carrier roller of the utility model changes φ 42*3.2*60 into, and the elastic force of spring has minimizing like this, and its in-to-in friction pressure correspondingly obtains reducing, and the flexibility of revolution of this carrying roller also just increases.Thereby can use less drag coefficient during drag calculation.
