Product Series:Harmonic drive

Product Number:DHDG-14-50-U-H14

This product is a short-cylinderhat-type reducer. Its model is 14 and its reduction ratio is 50. It is equippedwith the hollow axis mode at the input end to meet the demand for centralwiring. Its rated torque is 3.7N.m and itstransmission error is ≤90″.


1.Designed with anadvanced double arc tooth profile, it can enlarge 20%~30% teeth simultaneously.Compared with the traditional involutes tooth profile, it achieves asignificant improvement in accuracy, strength, rigidity, service life and otheraspects;

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

3.High transmission accuracy;

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

5.Stable transmission,no impact and reliable operation;

6.Simple structure, small volume andlight weight; under the same transmission ratio and loading conditions, itsvolume and weight can be reduced by 1/3~1/2 in contrast with general gearreducers.
