     Select the planetary gear reducer, China is in the hardened and soft tooth surface drive so far, at the same tim e consumption used in carburizing quenching scrapers and carbonitriding spiral lift.
The square of the planetary gear reducer features:
1) the planetary gear reducer, the tooth profile embossing mesh, the larger radius of curvature, and thus have a high understanding of strength. Phased double arc worm gear, the thickness of the tooth root
Tooth bending strength relative to a single planetary gear reducer improved a lot.
2) planetary gear reducer, the secondary tooth parameters sensitive design, such as the radius of tooth profile, tooth height, tooth waist and teeth to be the thickness according to strength requirements and to stop conditioning, has been designed to meet the different requirements of gear transmission.
3) planetary gear reducer to accelerate the machine drive is a point of meshing, before the full load of work and will need to run together, so that the point is understood that part of the surface deformation by the running-in and carrying understand. After plenty of running-arc worm gear competence with higher load carrying ability and the use of a longer life. In the operation process, the tooth profile of the absolute sliding velocity is approximately equal to the average tooth wear, normal wear and tear of the tooth surface without prejudice to the tooth precision, and the planetary gear reducer, the running-in process can play the parents of the finishing.
4) arc tooth worm gear meshing process to understand the regional high rolling speed to move along the tooth width direction of the circumferential speed of the moving speed of the gear, easy to constitute a smooth film elastohydrodynamic friction loss between the tooth surface. lower tooth wear reduces the progress of the transmission efficiency.
