Hypoid gear head HMTK

General-purpose gear heads for servo applications achieving high economic efficiency and short lead-time.
The hypoid gearhead HMTK is a high-efficiency type with right-angle shaft.
Output shaft: Hollow/solid
Compatible servo motors: 0.2 to 5.0kW
Reduction ratio: 1/5 to 1/200

Features

Economy

We have adapted general-purpose gearheads for servo applications, allowing us to deliver products economically and with Quick delivery.
-High efficiency

Compared to worm gears, it has less slippage and is more efficient. It consumes less power for the same output.
・Compact and space-saving

The compact body with reduced height allows for flexible installation and mounting. There are no restrictions on the installation angle, whether horizontal, vertical, or tilted.

・Output shaft backlash (approximate value)

Unit: minutes
Reduction ratio	5～10	15～100	120～200
angle	60	30	20

*This is not a guaranteed value.

Mounting type/shaft arrangement

H	US	UT

[Mounting type]: H: Hollow shaft type; US: Face mount type, single output shaft; UT: Face mount type, double output shaft; L: Foot mount type *Please contact us.

[Output shaft rotation direction]: When rotating clockwise toward the input shaft, viewed from the surface on the through-hole side; Two-stage type: Left rotation; 3-stage type: Right rotation

Type Name

HMTK: Right-angle shafttype using hypoid gears.

GMTK: A parallel shaft type that uses helical gears.

size

Indicates the rated input capacity.

Frame No.

This indicates the size of the reducer. For most models, this is the same value as the output shaft diameter.

It is automatically determined from the motor capacity and reduction ratio.

Mounting Type

L: Foot mount mounted type.

U: Face-mounted type.

F: Flange mounting type.

Face mount or flange mount?
It is automatically determined by the frame number.

Reduction ratio

Indicates the reduction ratio.

The range division corresponds to the frame number.

Shaft arrangement

For HMTK type

No symbol: If the mounting format is a hollow shaft type (H), the shaft arrangement symbol is not required.

S: When the mounting format is face mount (U), the solid output shaft protrudes toward the mounting surface.

T: A type with a solid output shaft on both sides.

For GMTK type

No symbol: No shaft arrangement symbol is required.

Mount Code

Specify the mount code that matches the motor you are installing.
