Consultation

Product Series:Harmonic drive

Product Number:DHDG-14-50-U-R11

This product is ashort-cylinder hat-type reducer. Its model is 14 and its reduction ratio is 50.The rigid input mode is adopted for the input end. Its rated torque is 3.7N.m and its transmission error is ≤90″. It is mainly used for light-load six-jointrobot, stamping manipulator, etc., especially the last joint.

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;

The service life of HAOZHI products is longer than L10:10000 hours L50:50000 hours.

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.
