Slewing bearing gear

Slewing bearing supporting gear is a gear assembly used in slewing bearings (also called slewing bearings or slew bearings). Slewing bearings are widely used in various heavy equipment and machinery, such as excavators, cranes, tower cranes, wind turbines and radar antennas, etc., and are mainly used to realize the rotation and load-bearing functions of the equipment.

Product Description

Functions of supporting gears for slewing bearings

Transmitting power: The supporting gears of the slewing bearing are connected to the driving device (such as an electric motor or a hydraulic motor) to transmit power to the slewing bearing, allowing the equipment to achieve rotational motion.
Load support: These gears have a strong design and can withstand large radial, axial and overturning moment loads, ensuring that the equipment is stable and reliable during work.
Positioning accuracy: The matching gears are precision manufactured to ensure high-precision rotational motion and meet the positioning accuracy requirements of various equipment.

Types of supporting gears for slewing bearings

Slewing bearing matching gears are mainly divided into the following types according to their tooth shape and structure:

External gear (external ring gear): The gear teeth are on the outside and are used to mesh with the external drive device.
Internal gear (ring gear): The gear tooth profile is on the inside and is used to mesh with the internal drive.
Spur gear: The gear tooth shape is linear, the structure is simple, and the manufacturing cost is low.
Helical gear: The gear tooth shape is oblique, with smooth meshing, low noise and strong load-bearing capacity.

Design and manufacturing

Material selection: Usually high-strength alloy steel is used, and the hardness and wear resistance of the gear are improved through heat treatment to extend its service life.
Precision machining: Use high-precision machining equipment, such as CNC machine tools, to ensure the size and shape accuracy of the gears.
Surface treatment: Improve the wear resistance and corrosion resistance of gears through surface treatment processes such as carburizing and nitriding.
