Helical Shaft Mount Speed Reducer
The Sumitomo Helical Shaft Mounted (HSM) Speed Reducer provides a convenient installation and removal method for speed reduction by mounting directly on the drive shaft. The Taper-Grip® bushing provides simple keyless mounting and easy removal.
The HSM can be quickly and simply mounted on to the machine shaft. A user-friendly fitting and removing system has been developed with the Sumitomo Taper-Grip® bushing, which does not require a key The particular advantages of the HSM are case hardened gears with optimized geometry for maximum load and high efficiency. This ensures optimum power drive in a compact design.
