Slewing drive is a new type of slewing product, usually also called slewing bearing. The main components of the slewing drive are a worm, slewing bearing, motor, casting base, and some standard parts such as bearings and bolts. Since the core component uses a turntable bearing (slewing bearing), it can bear axial force, radial force, and overturning moment at the same time. The rotary drive uses wheel and axle movement to reduce force consumption and play a role in safety protection. Compared with traditional rotary products, the slewing drive has the characteristics of simple installation, easy maintenance, and more significant installation space saving.

Basic Technology of Slewing Drive

Unique rotary deceleration products derived from slewing drive products with high height and large reduction ratio, simple structure, and convenient use and maintenance during slewing drive. Due to the use of slewing bearings as the follower and frame foundation, the inner and outer rings of the slewing bearings are used. The input and output of the driving power are realized separately so that the slewing drive can recognize the 360-degree rotation of the entire circumference without a dead point and install the driving power source based on the slewing support frame. Hence, its transmission efficiency is high, and a family of mechanical transmission devices. Because it is a deceleration device, it can also be called a slewing reducer, turntable reducer, or drive turntable.

Features of Slewing Drive

1. A large transmission ratio, which is more compact than the staggered shaft helical gear mechanism, can be obtained.

2. There is line contact between the meshing tooth surfaces of the two wheels, and its load-carrying capacity is much higher than that of the staggered-shaft helical gear mechanism.

3. Worm drive is equivalent to helical drive. It is a multi-tooth mesh drive, so the transmission is stable, and the noise is very low.

4. Self-locking of rotary drive. When the lead angle of the worm is less than the equivalent friction angle between the teeth of the meshing gears, the mechanism is self-locking, which can realize reverse self-locking.

5. The rotary drive transmission has low efficiency and severe wear. When the worm gear is driven, the relative sliding speed between the gear teeth is significant, so the friction loss is large, and the efficiency is low. And to dissipate heat and reduce wear, more expensive materials are often used, so the cost is higher.

Application Range of Slewing Drive

Slewing drives are mainly used in many industries, such as unique vehicle steering tables, heavy-duty flatbed trucks, and container cranes. Truck-mounted cranes, truck cranes, aerial work trucks, gantry cranes, small wind power stations, aerospace communications, satellite reception, solar tracking systems, and many other industries. Dönmə sürücüsü is used in the solar photovoltaic power generation industry, generally equipped with slewing or AC gear motor; the hydraulic motor is mainly used as power drive on construction machinery. Especially in recent years, the rapidly developing solar photovoltaic power generation industry has been widely used.
