Do you know how the bevel gear reducer is driven?

2021-07-02

The bevel gear reducer mechanism drives the roller mill. In order to reduce the speed of the K series reducer, we use a helical gear and two planetary gear stages (vertically distributed). The floating gear in the first gear shift stage is connected to the helical gear shaft through a raised double input gear type coupling.

Axial support is achieved by a plastic thrust plate. This degree of freedom with space allows the inner sun gear to be set in a way that ensures uniform meshing of the gear teeth and uniform load distribution among the three bevel gears.

The bevel gear reducer is located on its axis in a spherical shape and is supported by a roller bearing that can be automatically aligned, so that the bevel gear can automatically adapt to the load curve of its teeth. Although the carrier of the bevel gear reducer is suspended and can be set freely, its torque is transmitted to the inside of the fixed second gear through the coupling teeth mounted on the coupling shaft (hollow) or its upper end On the center wheel. The bottom end of the coupling shaft (hollow) is firmly connected to the planetary carrier.

The carrier of the K series reducer is vertically supported, that is, its weight. The steering rod supported by the anti-friction bearing is carried by a fixed flange located on the bevel gear carrier. The torque is transmitted to the gears and is evenly distributed on the 6 gears. Through the structure of bevel gears in pairs and a K series reducer that can be adjusted freely without support, to ensure the even distribution of torque.

The radial ball bearing guides this planetary gear. Another further task of this radial bearing is to guide the thrust plate fastened to the carrier. The two annular sleeves of the inner gear teeth are both firmly connected to the outer shell through a common annular carrier.

Because of this free movement transmission of the bevel gear reducer, the interference accuracy of the entire upper gear mechanism is reduced to a lower level. The oscillating motion of the grinding bowl or thrust plate caused by the impact of the grinding object and the grinding stick will not affect the gear teeth.
