Worm Slewing Drive

Safety of Worm Slewing Drive

Compared with traditional slewing products, worm slewing drive (slewing drive) has the advantages of simple installation, easy maintenance, and greater space savings. The worm gear transmission has the characteristic of reverse self-locking, which can achieve reverse self-locking, that is, it can only be driven by the worm gear, and cannot be driven by the worm gear to move. This feature enables worm slewing drive (slewing drive) to be widely used in lifting, high-altitude operations and other equipment. While improving the technological content of the host, it also enhances the stability and safety factor of the host's operation.

Precautions for the installation and use of worm rotation drive

1. The specified bolts should be used for tightening bolts, and full thread bolts cannot be used. Do not use old bolts, nuts, and washers, and do not use open washers such as elastic washers

2. The inner and outer raceways of the positioning worm slewing drive have a soft belt that should be placed on both sides of the main load plane. Staggered by 90 degrees from the main load zone. There is a blockage or an "S" mark at the soft band. In addition, it is necessary to check the fit between the worm rotation drive and the installation surface, usually using a feeler gauge. If the fit is not good, appropriate materials should be used to fill it. Welding operations on the support are prohibited after the installation of the worm rotation drive.

The use of wheel axle motion in the slewing drive auxiliary device can reduce force consumption and provide safety protection. In addition to being used in daily solar power generation systems, slewing drives are also commonly used in fields such as special vehicle steering platforms, heavy-duty flatbed transport vehicles, container cranes, truck mounted cranes, aerial work vehicles, crane cranes, gantry cranes, small wind power stations, aerospace communication, satellite reception, etc. The slewing drive pair is used in the solar photovoltaic power generation industry, generally equipped with a DC planetary reducer motor or an AC reducer motor; Hydraulic motors are mainly used as power drives in construction machinery.

A slewing driver is an integrated device consisting of a gear slewing ring, a drive gear, a housing and a motor (electric or hydraulic). Designed for axial, radial and moment loads.

Socare slewing drives use hourglass (double-enveloped) worm technology to improve load handling, efficiency and accuracy.

Socare manufactures a wide range of drive types, model sizes, performance ranges, sealing options and mounting characteristics.

Standard model sizes from 75mm to 800mm in diameter

Performance Load characteristics range from:

-6kNm to 220kNm holding torque

-200Nm to 63kNm output torque

-500Nm to 271kNm overturning moment load capacity
