1. Description 

Slewing drives,designed in integrated structure,compose of housing,slewing bearing,motor and worm.They are widely used in energy industry,machines and rotating parts of port machine. Because of integrated structure,they features of saving space,easy to install and high rigid.They can be without motor, or driven by Hydraulic motor,Electric motor,Pneumatic motor.


2. Function

Our slewing drive is able to withstand large axial force, radial force, and overturning moment. It can the turntable or stand for horizontal and tilt angle rotation.


3. Application Field

Metal cutting and forming: These applications need full precision in positioning the workpieces. Slewing drives with a reduced backlash option deliver high accuracy results under varying conditions.
 
Mining: Slewing drive mechanisms are ideal for applications demanding a maximum torque capacity along with shock loading resistance. They also offer ratio reduction and present a profile low enough to support an extensive selection of mining equipment.
 
Construction: Slewing drives operate with systems providing power to construction equipment that is subject to heavy loads of variable operation. They are appropriate for this field due to the ability to produce high torque and smooth operation in limited spaces. Crowded construction areas are typical with equipment such as winches, hoists, and cranes.
 
Printing: Printing press rolls keep precision print registration at top speeds. A slewing drive supports rapid changes in the operating speed. Compact drives with low inertia perform better where rapid starting and stopping is necessary than devices with heavier gearing featuring multiple stages.


Application Examples


Engineering Machinery
The slewing drives are widely used for engineering machinery.


Medical Equipment

The slewing bearings are used for Medical Equipment like CT equipment and Gamma Knife.

Port Equipment

The slewing drives are used for boat lift, offshore crane and reach stacker.


Other Appliances

The slewing drives are also applied in other areas like welding and automation.

Hand Operated Screw Jack for Crank Table
Hand Operated Screw Jack for Crank Table

The working principle of the hand operated  worm gear screw jack is that the worm (also called the input shaft) is manually rotated by the hand wheel, the worm wheel is rotated by the worm, and the trapezoidal lifting screw is moved by the rotating worm wheel. The linear motion speed of the  worm wheel manual screw jack trapezoidal lifting screw depends on the thread size and the worm gear speed ratio. Hand Operated Screw Jack is composed of hand wheel or hand crank and a worm gear screw jack.It is ideal solutions for applications where electricity or power generators is inconvenient or dangerous.
