Substantial power roller chains with enhanced fatigue power and effect power
HI-PWR-S roller chains are enhanced in fatigue power and influence power without modifying the dimension from the pin length route of normal roller chains. Plates are enlarged, and the machining accuracy and assembling accuracy of components are improved. The roller chains hold high transmission efficiency for applications from reduced to high speeds and therefore are powerful adequate to stand up to long-term use.
Proposed uses
?Compared to regular roller chains, HI-PWR-S roller chains are higher in highest kilowatt rating by about thirty % inside a medium to low speed assortment. They exhibit excellent capability in locations in which substantial shock loads are applied, drive units for frequent start/stop, and also in substantial pace 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.
Choice of chains
Usually, choose your chain with reference to “Designing of Chain Transmission” and in addition to the tables of “Drive Performance” and “Dimensions” of HI-PWR-S variety roller chains.However, only for a unique situation of minimal velocity and much less shock, “Low-speed selection” can be applicable.
HI-PWR-S Roller chains and ANSI common chains would be the similar in basic dimensions. Use ANSI normal sprockets.
Connecting back links and offset backlinks
Use H connecting back links for HI-PWR-S. In an H connecting link, the pins are lightly interference-fitted with the connecting plate. To the connection involving the connecting plate as well as the connecting pins, spring pins are applied in lieu of cotter pins for a typical roller chain.
The center plates of an H connecting hyperlink for multiplex chain has bushings pressed in.
HI-PWR-S roller chains tend not to have any offset hyperlink. Use an even variety of backlinks.
Never make the holes from the connecting plate bigger and hardly ever make the pins thinner to facilitate the function for fitting the pins into the connecting plate, considering that otherwise the fatigue power is going to be lowered.
