Spare parts for chains Driving roller
Drive roller chains are made up of external and internal links. Individual circuit components considered external plate. and ext. links, rollers, bushings and rollers. inside the plate. link attached to the sleeves with a tension and forming the unbreakable connection. Roller comes free manner into the sleeve and thereby forming a cylindrical hinge connection. Outer plates are pressed with rollers at the ends flared. Clip on the sleeve can rotate freely engaged with the teeth of the sprocket. In mobile connections sleeves with rollers and the rollers there is a sliding friction when contacting rollers with teeth sprocket arises rolling friction.
are made 1, 2, 3, 4-row and respectively referred to as PR, 2np, 3PR, 4PR. The number of rows of chain almost in proportion to the load-bearing capacity. Their use makes it possible to significantly reduce the transmission dimensions in a plane which is perpendicular to the shaft axes. Produce them from the components, as well as single-row, the difference lies in the increased length of the rollers. Due to the presence of 2 types of links of the chain units the number of contour should be even. If necessary, use chains with an odd number of links used special transitional links. There is also a circuit with curved plates and the 1st batch link - IF. They use the same links, in this regard, perhaps as an even and odd number of links. They longitudinally more pliable, and because of this, are used for shock loads.
