Precision Differential Reducers for TCG Series 3212-4012, NSP Series

Available to Combine with TCG series large frame numbers 3212 and 4012.

It is possible to collectively select a combination of TCG series and recommended reducers from ours, so reduce assembly man-hours.


The internal gear of this differential reducer has a trochoid tooth profile, which enables high-precision positioning while maintaining the strength to withstand the maximum working load of the TCG series.

The high-precision crossed roller bearing is used for this output shaft, and run-out accuracy and shaft load are at a high level.

The main body has an output shape that allows the roller pinion to be attached directly, so it is possible to use it from the beginning with the NSP dedicated roller pinion installed.

In addition, the flange shape and slotted holes for preload adjustment are standard specifications that take into consideration the incorporation into

equipments, which contributes to the reduction of design and assembly man-hours on the part of the customer.

Also, since it is a grease-filled type reducer, it can be used maintenance-free up to the rated life.


*NSP series are sold as a reducer and a dedicated roller pinion set. Therefore, please note that it is not compatible with the standard roller pinion model "CPA" and "CPC".

Precision Differential Reducers for TCG Series 3212-4012  NSP Series

Highlights

High precision

More than one contact of precision trochoid gear with high-precision roller enables ever higher force transmission.

High rigidity

High contact ratio and resultant load dispersion realizes the extremely high degree of rigidity.

Easy motor mounting

With the availability of various manufacturers’ servo-motor attachments, motor can be installed immediately after purchase.

Reduction assembly and selection man-hours

NSP series are already set the roller pinion due to reduce the customer’s man-hours.

In addition, the design of the dedicated reducer shape that matches the conbination with the TCG series have improved the ease of incorporation into the equipments.

*1 This allowable radial load value is realized when the load positioned in the axial direction is applied to the pitch circle diameter of the roller pinion.

*2 This value is realized when the reducer is used in combination with the roller pinion.

*3 The recommended motor capacity is a guideline. Please select the motor before use.

*4 Please contact us if you plan to use it for continuous rotation or high-frequency repetitive operation.
