High power roller chains with enhanced fatigue power and impact strength
HI-PWR-S roller chains are enhanced in fatigue strength and affect strength without the need of transforming the dimension inside the pin length direction of normal roller chains. Plates are enlarged, and the machining accuracy and assembling accuracy of components are enhanced. The roller chains hold high transmission efficiency for applications from reduced to higher speeds and therefore are strong ample to withstand long-term use.
Proposed makes use of
?In contrast to conventional roller chains, HI-PWR-S roller chains are higher in optimum kilowatt rating by about thirty % in the medium to reduced speed selection. They exhibit great capability in areas wherever significant shock loads are applied, drive units for regular start/stop, as well as in large velocity applications.

?Civil engineering machines this kind of as skid steer, trenchers, trucks, cranes, agitating trucks, forklifts and drive units for conveyors, elevators, stackers, and so forth.
Selection of chains
Generally, choose your chain with reference to “Designing of Chain Transmission” and also towards the tables of “Drive Performance” and “Dimensions” of HI-PWR-S kind roller chains.Even so, only to get a exclusive situation of low speed and less shock, “Low-speed selection” can be applicable.
Sprockets
HI-PWR-S Roller chains and ANSI common chains would be the similar in standard dimensions. Use ANSI common sprockets.
Connecting back links and offset back links
Use H connecting hyperlinks for HI-PWR-S. In an H connecting website link, the pins are lightly interference-fitted with the connecting plate. For the connection involving the connecting plate as well as connecting pins, spring pins are used in place of cotter pins for a common roller chain.
The center plates of an H connecting link for multiplex chain has bushings pressed in.
HI-PWR-S roller chains usually do not have any offset website link. Use an even quantity of backlinks.
Never ever make the holes of your connecting plate greater and never make the pins thinner to facilitate the get the job done for fitting the pins to the connecting plate, since otherwise the fatigue power will probably be lowered.
