Short Description:

These internal spur gears and internal helical gears are used in planetary speed reducer for construction machinery. Material are middle carbon alloy steel . Internal gears usually could be done by either broaching or skiving ,for big internal gears sometimes produced by hobbing method as well .Broaching internal gears could meet accuracy ISO8-9 ,skiving internal gears could meet accuracy ISO5-7 .If do grinding ,the accuracy could meet ISO5-6.

Features

Customized broaching power skiving shapping gringding milling internal gears，Planetary speed reducer used in large and medium-sized construction machinery  has many characteristics compared with other types of gearbox, such as compact structure, high transmission efficiency, small between tooth load, stiffness big, easy to realize power shift transmission, etc. This kind of gearbox consists of several basic planetary row by fitting the transmission speed reducer, rely on shift gear shifting clutch and brake control component. 

Application

The planetary reduction mechanism is used in the transmission part of low speed and high torque, especially in the side drive of construction machinery and the rotating part of tower crane.This kind of planetary reduction mechanism requires flexible rotation and strong transmission torque capacity.

Planetary gears are gear parts widely used in planetary reduction. At present, the requirements for the planetary gears to be processed are very high, the requirements for gear noise are high, and the gears are required to be clean and free of burrs. The first is the material requirements; the second is that the tooth profile of the gear meets the DIN3962-8 standard, and the tooth profile must not be concave , third, the roundness error and cylindricity error of the gear after grinding are high, and the inner hole surface .There are high roughness requirements.
