Harmonic reducer life:
The harmonic drive of harmonic reducer uses the elastic deformation controlled by the flexible elements to transfer the motion and power. It is small in size and high in accuracy, but its disadvantages are the limited service life of the flexible wheel, the non impact resistance, and the poor rigidity compared with the metal parts. The input speed cannot be too high.
Generally, the service life of harmonic reducer is about 5000 to 10000 hours. enter
Small, light weight: under the same torque and speed ratio, compared with the ordinary reducer with the same transmission ratio, its parts are reduced by 50%, and its volume and weight are reduced by about 1 / 3 or more.
Large torque: the harmonic reducer has large bearing capacity, and the flexible wheel is made of special steel with high strength and fatigue resistance. At the same time, the number of meshing teeth is about 30% of the total number of teeth. That is to say, the number of teeth bearing load is large, and the force of each tooth is very small. In the case of the same material and speed ratio, the load bearing capacity is much higher than other drives.
High transmission efficiency: high transmission efficiency of harmonic reducer. Compared with other drives with the same speed ratio, the harmonic drive has high efficiency because of the small number of moving parts and the low speed of meshing tooth surface, and the highest efficiency is about 96%.
Quiet operation: when the harmonic reducer is moving, the teeth are meshed in and out along with the deformation of the flexible wheel, and gradually enter and exit the rigid teeth. During the meshing process, the tooth surface contacts, the slip speed is small, and there is no sudden change. Therefore, the operation is stable, without impact, and the noise is small
