Slew Drive Intruduction & Tips
How to select suitable slewing drive?
  • August 25,2017.

Slewing drives have many appliances. They are widely used not only in excavators, tower cranes, mobile cranes and crawler cranes, but also in other construction machines, engineering machines, harbor machines, metallurgical machines, light industrial machines, military equipments and wind generators, solar PV utilities etc.
types of slewing drives

Slewing drives are like silent heroes, delivering the positional accuracy and mechanical control that make much of modern technology possible. The slewing drives include single /two axis slewing drive,open/enclosed housing slewing drives,single/two worm slewing drives etc. How to choose suitable slewing drives? The following questions will give you some indications.

What are your actual performance requirements?

The most cost effective and reliable drive design will be the one that fits a minimum size profile while also meeting particular structural, power, duty cycle and survivability holding torque values. Fully appreciating your actual operating requirements is critical when evaluating slewing drive designs intended to meet them.

What are your expected environmental conditions?

Your drive’s protective outer casing must be sufficient to ensure a long mechanical life, reliable performance and adequate defense against the surrounding elements. Will the drive be exposed to dust, dirt or other particulate contaminants? Will water or other liquids be a concern? Lude Transmission slewing drives are available with IP55, IP65, IP66 and other standard rated housings for various environmental conditions, as well as fully exposed open architecture anything you need to confront even the most challenging stresses.

What are your expected axes of rotation and motion ranges?

A best-fit slewing drive design will easily and smoothly accommodate a necessary range of motion about one or more rotation axes. Lude Transmission drives can be designed with single or dual-axis rotation capability in any specific motion range.

What are your required backlash tolerances?

Backlash, also called play or lash, refers to the slewing drive’s accuracy. It is a measure of the clearance existing between the gear teeth, gaps that result in lost motion potential in the drive. Greater backlash tolerances looser gear fittings may be necessary to accommodate thermal expansion, bending stresses or other engineering concerns. Backlash, however, limits the accuracy of the drive and the efficiency of energy transmission between the gears.

What are your power requirements?

A slewing drive can be designed using one of many different common types of power systems. Lude Transmission drives are available with electric (DC brushed/brushless and AC motor), hydraulic and hand rotation power controls.

Choosing the right slewing drive can be a detailed and complicated process, but it is not so difficult and you do not need to deal with it alone. Lude Transmission’s engineers can help you streamline processes and help your organization pick the most cost-effective, highly reliable rotary drive solution as per your specific application needs.
