Substantial power roller chains with improved fatigue strength and effect power
HI-PWR-S roller chains are enhanced in fatigue power and influence power without altering the dimension while in the pin length course of common roller chains. Plates are enlarged, and also the machining accuracy and assembling accuracy of components are improved. The roller chains hold high transmission efficiency for applications from low to substantial speeds and are powerful sufficient to stand up to long-term use.
Proposed utilizes
?Compared to standard roller chains, HI-PWR-S roller chains are increased in optimum kilowatt rating by about 30 % within a medium to reduced velocity variety. They exhibit superb capability in places exactly where huge shock loads are applied, drive units for frequent start/stop, and in addition 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
On the whole, 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 sort roller chains.Nevertheless, only for a special case of reduced velocity and much less shock, “Low-speed selection” is additionally applicable.
HI-PWR-S Roller chains and ANSI typical chains will be the similar in fundamental dimensions. Use ANSI regular sprockets.
Connecting backlinks and offset backlinks
Use H connecting back links for HI-PWR-S. In an H connecting link, the pins are lightly interference-fitted together with the connecting plate. To the connection involving the connecting plate as well as the connecting pins, spring pins are utilised in lieu of cotter pins for a conventional roller chain.
The center plates of an H connecting hyperlink for multiplex chain has bushings pressed in.
HI-PWR-S roller chains usually do not have any offset hyperlink. Use an even quantity of hyperlinks.
By no means make the holes of the connecting plate larger and under no circumstances make the pins thinner to facilitate the function for fitting the pins into the connecting plate, because otherwise the fatigue strength will likely be lowered.
