Product Series:Harmonic drive

Product Number:DHS-25-100-U-OC11

This product is ahat-type reducer with a standard length. Its model is 25 and its reductionratio is 100. It is equipped with the European coupling at the input end. Itsrated torque is 67N.m and its transmission error is ≤60. It is mainly used forlight-load six-joint robot, stamping manipulator, etc.

1.Designed with anadvanced double arc tooth profile, it can enlarge 20%~30% teeth simultaneously.Compared with the traditional involute tooth profile, it achieves a significantimprovement in accuracy, strength, rigidity, service life and other aspects;

2.The transmissionratio is large and the range is wide; the transmission ratio of a single-stagetransmission i=30~160;

3.High transmissionaccuracy;

4.The backlash can beadjusted easily; zero backlash transmission can also be achieved easily;

5.Stable transmission,no impact and reliable operation;

6.Simple structure,small volume and light weight; under the same transmission ratio and loadingconditions, its volume and weight can be reduced by 1/3~1/2 in contrast withgeneral gear reducers.
