Large electrical power roller chains with improved fatigue strength and effect power
HI-PWR-S roller chains are enhanced in fatigue power and impact strength devoid of altering the dimension while in the pin length path of regular roller chains. Plates are enlarged, as well as machining accuracy and assembling accuracy of components are improved. The roller chains hold high transmission efficiency for applications from low to substantial speeds and therefore are impressive sufficient to stand up to long-term use.
Advisable employs
?Compared to standard roller chains, HI-PWR-S roller chains are increased in optimum kilowatt rating by about thirty % inside a medium to very low velocity variety. They exhibit fantastic capability in destinations exactly where huge shock loads are utilized, drive units for frequent start/stop, and in addition in large speed 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 on.
Selection of chains
On the whole, select your chain with reference to “Designing of Chain Transmission” and in addition to your tables of “Drive Performance” and “Dimensions” of HI-PWR-S sort roller chains.Having said that, only for a distinctive case of reduced velocity and less shock, “Low-speed selection” is additionally applicable.
Sprockets
HI-PWR-S Roller chains and ANSI normal chains would be the identical in essential dimensions. Use ANSI regular sprockets.
Connecting backlinks and offset hyperlinks
Use H connecting backlinks for HI-PWR-S. In an H connecting link, the pins are lightly interference-fitted together with the connecting plate. For your connection amongst the connecting plate and the connecting pins, spring pins are utilised as an alternative to cotter pins for any 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 hyperlink. Use an even quantity of hyperlinks.
Hardly ever make the holes of the connecting plate larger and under no circumstances make the pins thinner to facilitate the do the job for fitting the pins to the connecting plate, because otherwise the fatigue strength will likely be lowered.
