Utilizing the gear and reducer manufacturing technologies cultivated since NISSEI foundation, in August 2021 we launched High Stiffness Reducers that employs an eccentric oscillating differential reduction mechanism. This product contributes to higher speeds and compactness of robots and FA equipment and gives greater design freedom to our customers. We will keep expanding our product lineup to meet the diverse needs of our customers.

[Structure] A structure with high precision.
- ・In accordance with the crankshaft (input shaft) rotation, the two planetary gears revolve while autorotating,
transmitting their movement through the reaction pin and metal to the output cross roller bearing. - ・Even with on a single stage gearing , the two planetary gears ( 180° offset ) can phase simultaneously
and engage with internal gears, avoiding imbalance during rotation.
[Features] Large Hollow Shaft with High Stiffness and High Torque
The use of a differential reducer mechanism (eccentric oscillation type) achieves high torsional rigidity and allowable torque. Because the gear engagement ratio remains effectively the same even when the reduction ratio changes, a large torque can be obtained even at a low reduction ratio. In addition, the large hollow diameter makes it easy for wiring, piping, shafts and the like to go through, greatly enhancing the degree of freedom you can enjoy in designing robots and devices. Helps improve the productivity.
Designed for maximum performance.
The use of a differential reducer mechanism (eccentric oscillation type) achieves high torsional rigidity and high allowable torque. As well, the cross roller bearing integrated with the output shaft keeps the unit compact while ensuring higher moment stiffness. Even if the reduction Ratio changes, the Meshing does not change so the allowable torque is constant. High torque can be obtained even at low reduction ratios.
