How to choose a slewing drive with suitable accuracy level for equipment?

In the slewing drive design, in order to fit different working conditions and different applications, we will choose different accuracy levels, mainly reflected in what we often call the tooth backlash value. So how can we choose a rotary drive with the right level of accuracy for our equipment? So how can we choose a slewing drive with the suitable accuracy level for equipment?

To figure this out, first we need to understand that in the slewing drive, gears and rings are the main components to transmit motion and power, and the backlash value mainly depends on the adjustment of these two components. The engineers of Unique Transmission will design the slewing drives according to the working conditions and other performance parameters provided by the customer, in accordance with the following points:

1.Max power capacity

2.Min size

3.Min noise (quiet operation)

4.Rotation demand (position)

The engineers of Unique Transmission calculate and determine the accuracy level of one of them according to the usage requirements of the gear transmission, and then determine the accuracy level of other usage requirements according to the requirements of other aspects. After comparing previous product designs, performance tests, experience accumulated during use, and references on gear accuracy levels, the designed gears are compared in terms of usage, operating conditions and technical performance before the required accuracy level can be finally determined.

Unique Transmission design engineers have summarized the operating conditions used for the following three accuracy levels of gears.

1. Grade 6 tooth accuracy: use gears that require high speed and smooth rotation, and have high efficiency and low noise, and indexing requirements.

2. Grade 7 tooth accuracy: for high speed, small load, and reversing gears. Gears that need to have motion fit, medium speed reducer gears.

3. Grade 8 tooth accuracy: no special requirements for accuracy, generally with mechanical gears and ordinary reducer gears.
