Slewing drive introduction
1. Introduction of LYHY slewing drive
LYHY Slewing Drive movement can reduce power consumption, since the security role. In addition to the field of use in the daily solar power systems are usually used for Special vehicle, heavy-duty flat-panel truck, container cranes, truck mounted crane, automobile crane and aerial vehicles, cranes, gantry cranes, small wind power stations, space communications, satellite receiver, etc...The Slewing Drive in the solar photovoltaic industry, the general configuration DC planetary reduction motor or AC geared motors; Main configuration of the hydraulic motor as a power-driven construction machinery
LYHY Slewing Drive principle of the large transmission ratio of the deceleration device to transmit motion and power between the two axes staggered in space. The Slewing Drive transmission is usually the case of the main components of the worm and wheel bearings, shell, and the power source
As the core component of turntable bearings, can withstand the axial load, radial load and overturning moment.
2. Structure
Slewing drive can be divided into two different structures as per different applications.
Light load slewing drive
Heavy load slewing drive
The dimensions of slewing drives include 3 inch, 5 inch, 7 inch, 9 inch, 12 inch, 14 inch, 17 inch, 21 inch and 25 inch.
3. Features:
Slewing drive is a special bearing. And a slewing drive usually consist of slewing bearing, worm shaft, housing, bearing, motor and so on. Motor drive the worm shaft, the outer ring of slewing bearing will rotate, the outer ring output the torque through flange while the inner ring of slewing bearing is fixed in housing.
LYHY Slewing Drive and rotary products, compared with the ease of installation, ease of maintenance, Installation space savings advantages to a greater extent.
4. Application:
Slewing drives are widely used in aerospace area, solar power systems, wind turbines, satellite broadcasting system, and engineering machinery like truck cranes, and man lifts, etc. Recently years, it has been prosperously used in photovoltaic power generation systems, special vehicle, heavy-duty flat-panel truck, container cranes, truck mounted crane, automobile crane and aerial vehicles, cranes, gantry cranes, small wind power stations, space communications, satellite receiver, etc.
