Effect of parameters of self-aligning idler and belt conveyer on the force to correct deviation of the belt;

Designed a kind of twin helix hinge joint adjustable idler which has high effective upon aberrancy of extensible belt conveyor.

In manufacture process of unitary spinning no-mandrel roller,spinning forming of roller sleeve is the key process,the thin wall hollow sleeve was installed in spinning machine,and the goal of forming can be achieved by means of the power spinning of cycloid to cause the work piece local distortion.

In view of the problems existed in rollers of belt conveyor at present, a new structure of unitary spindleless roller is advanced.

This article explains the various reasons of the sl anting of the belt i n belt conveyors and the corresponding anti-slanting adjusting measures to be ta ken; introduces several main anti-slanting adjusting rollers, analyses the opera ting principles of anti-slanting adjusting rollers and recommends a kind of perf ect rotating taper anti-slanting adjusting rolle
