Hollow-Shaft POWER-LOCK Type
Hypoid gear head HMTK Type
A special hollow shaft with POWER-LOCK enables keyless coupling and gives rise to further hollow shaft functions.
Mounting and unmounting are easy, and a reduced number of machinery device parts helps save space.
Features
- ・There's no need for a keyway on the driven shaft.
- ・Mounting and unmounting of the reducer are easy.
- ・There's no backlash with the driven shaft.
- ・A special shaft-end cover is available. (Hypoid motor: 0.2 kW to 0.4 kW, 0.75 kW, reduction ratios 1/5 to 1/50 only)

- Note) The driven shaft to be coupled to the hypoid motor hollow shaft should have a dimensional tolerance of ϕS h6, a finish length of dimension E or longer, and a surface roughness of 12S or less. The finished surface of the driven shaft should be located within the range indicated by E.
- Note) For 0.2 to 0.4 kW and 1/5 to 1/50 of 0.75 kW, a special shaft-end cover is available.
