The prime mover (usually an electric motor, the same applies below) is connected to the horizontal input shaft of the reducer via a coupling, driving the grinding disc of the vertical mill through the reducer's vertical output.
The reducer employs a two-stage bevel gear-planetary reduction transmission or a three-stage bevel gear-parallel shaft gear-planetary reduction transmission structure. The planetary transmission uses a three- or four-way flow structure, employing various methods to achieve load sharing. The reducer's bevel gears, spur gears, sun gear, and planetary gears all undergo hardened and ground tooth surface processing, achieving a gear precision of grade 6 or higher. The reducer housing is a welded structure, possessing sufficiently high strength and rigidity. Its excellent structural design ensures the reducer can withstand sufficiently large axial and radial loads.
The reducer output shaft offers two design options: axial sliding pair and rolling pair. The output flange support uses either hydrostatic thrust bearings or hydrostatic thrust bearings, depending on the magnitude of the vertical axial load. Monitoring elements are installed at the locations of critical transmission components and the lubrication system, allowing connection to a monitoring system to ensure safe equipment operation.
This series of speed reducers features high power density, high efficiency, low noise, smooth operation, low vibration, and long service life. Its main technical specifications have reached the advanced level of similar products abroad.
