Product Info Reducer
A reducer is a mechanical device that uses gears to reduce the rotational speed of the power obtained from the output shaft of a power source such as a motor and output it.
The ratio of the number of gear teeth on the input and output sides is the reduction ratio, and the output shaft can obtain torque that is inversely proportional to the reduction ratio.
We offer a lineup of three gear types: helical gears, hypoid gears, and worm gears. You can choose from the motor specifications, shaft arrangement (parallel shaft/ right-angle shaft), and output shaft shape (solid/hollow) that suit your purpose.

*Self-lock: A function possessed by worm gears that prevents the input shaft from rotating from the output shaft.
Generally, it has a single reduction stage with a reduction ratio of 1/60.

Basic knowledge of miter bevel gearboxes
A miter bevel gearbox is a mechanical element that changes the direction and distributes torque obtained from a single power source, enabling flexible layout and easy synchronized operation of multiple mechanisms.
The basic functions are...
1. Change the direction of force transmission by 90°.
2. Change the direction of force transmission by 90° and distribute it left and right (up and down).
Examples of applications include:
3. Line up Miter Gear Box and connect the cross shaft to form the input.
Rotate the lateral axis.
4. Use a lateral 2-axis type and input from the cross axis.
Rotate the opposing lateral axis in the opposite direction.
