Product Description

LYHY Bearing is short for LUOYANG HUAYANG SPECIAL HEAVY-DUTY AND LARGE BEARING MANUFACTURING CO., LTD.



1. Introduction of LYHY heavy load slewing drive
Slewing Drive is also called slewing gear, worm gear, worm drive, rotary drive, slew drive, worm gear reducer and rotary drive unit. At present the majority of such devices are caller Slewing Drive.
LYHY heavy load slewing drive is usually composed of a slewing ring, worm, casting housing, and standard components likebearing and bolts, etc. While used in photovoltaic power generation system, the slewing drive is usually used in combination with DC planetary speed reducer motor and AC speed reducer motor. While used in engineering equipment, it is regularly used in combination with hydraulic motor to function as power driving system.

2. Structure
According to the raceway diameter of the slewing ring, a heavy load slewing drive include M3 ich, M5 inch, M7 inch, M9 inch, M12 inch, M14 inch, M17 inch, M21 inch, M25inch, H14 inch, H17 inch, H21 inch and H25 inch.




3. Features:
Heavy load slewing drive is a special bearing. And a slewing drive is usually composed of a slewing ring, worm, casting housing, and standard components like bearing and bolts, etc.
Slewing drive is able to sustain more axial load, radial load and tilting moment. Turntable or frame rotates at azimuth and elevation driven by slewing drive.




4. Application:
Slewing drives are widely used in solar power generation tracking system, timber grab, special vehicle, heavy-duty flat-panel truck, container cranes, overhead working truck, truck mounted crane, automobile crane and aerial vehicles, cranes, gantry cranes, small wind power stations, space communications, satellite receiver, etc.




LYHY can also design and make other standard and non-standard Slewing Drives as per customer's different technical requirements. For more information about the slewing drive, please contact LYHY Bearing sales department. We will give you the best technical support.
