Double moduli high-accurate planet reducing mechanism

Abstract

The invention relates to a double moduli high-accurate planet reducing mechanism. At present no high-accurate planet reducing mechanism is high in precision, compact in structure, small in meshing clearance and strong in bearing capability. The double moduli high-accurate planet reducing mechanism is characterized by comprising an output shaft, an output shaft oil sealing, a secondary gear ring shell body, a plurality of secondary planet gears, a primary gear ring shell body, an intermediate planet carrier, a plurality of primary planet gears, a primary sun gear, a coupling bearing, a simple-clamp type locking ring, a rear cover, a secondary sun gear, bearings, a coupling and a secondary planet carrier. The output shaft is installed inside a secondary gear case shell body through a front bearing, the secondary planet carrier is fixed at one end of the output shaft, the secondary planet gears are all installed on the secondary planet carrier, the secondary sun gear is installed in a secondary sun gear cavity of the secondary planet carrier, the primary planet gears are meshed with the primary gear ring, and the primary planet gears are all meshed with the primary sun gear. The double moduli high-accurate planet reducing mechanism is compact in structure, small in back lash, and high in concentric degree and repeated location.

Problems solved by technology

However, this increases the length of the overall high-precision planetary reduction mechanism, which cannot meet the requirements of small size, light weight and compact structure of the high-precision planetary reduction mechanism.

[0006] 2. Scalloped and cylindrical gear transmission: It is a helical cylindrical gear transmission, which belongs to a form of cylindrical gear. The helical gear has a high load-carrying capacity, and it is relatively messy in production and processing. Increased costs

[0010] At present, there is no high-precision planetary reduction mechanism that can meet the requirements of various high-precision equipment, and has a compact structure, small meshing clearance, high concentricity and repeat positioning accuracy, and strong bearing capacity.
