Standard Differential Reducer PSR series
A differential speed reducer featuring high rigidity and extreme flatness made possible through thin cross roller bearings and a pin-and-hole type drive.
Its sleek, polished design contributes to the shortening and compactness of a variety of equipment.
Technical InformationHighlights
-
Ultra-flat and compact design
The adoption of a differential reduction mechanism and a thin cross-roller bearing has enabled an ultra-flat form. This contributes to the realization of contraction and compactification of equipment.
-
High rigidity
High contact ratio and load dispersion have realized extremely high rigidity.
-
High Accuracy
High transmission accuracy made possible through multiple meshing of high-accuracy rollers and high-precision trochoidal gears.
-
Small backlash
High-precision positioning with a backlash under 3 arcmins achieved by optimizing each component’s clearance.
-
High Efficiency
Appropriate pressure angle settings for smooth operation and high efficiency.
-
Maintenance-free
Grease-filled and maintenance-free. No need to refuel and no restrictions on mounting position.
-
Motor Attachment Standardization
The PSR Series has standardized motor attachments for servo motors of various manufacturers, allowing the motor to be immediately installed after purchase.
