Roller Chain is not recommended for drives with vertical shafts, but providing the drive is well engineered, and certain basic rules followed, a satisfactory drive can be achieved. As the chain is supported by its side-plates on the sprockets, it is essential to use sprockets with high numbers of teeth (minimum 25 teeth) to spread the load. To ...

10%In the vertical rolling process, the rolling depth (RD) is known to be the most significant parameter, which is controlled by the amount of force applied on the roller (see Fig. 7 ). To investigate the residual stress distribution in numerical simulations, the RD values of 0.1, 0.2, 0.5, 0.75 and 1 mm have been considered in the analyses. Fig. 7
