Why calculate and measure the starting torque of the spur gear slew drives?

Spur gear slew drive is also called gear type slew drive, it’s a component that includes slewing ring, transmission pinion, housing and adapter flange. It can achieve 360° rotation without dead angle, can bear axial force, radial force and tilting force at the same time, has a certain gear ratio, compact structure, powerful, strong and durable. Like all speed reducers and all slewing bearings, gear type slew drives have different starting torques under different working conditions.

The starting torque of the spur gear slew drive directly affects the customer’s choice of reducer and motor. For example, if the starting torque of the spur gear slew drive is large, it needs to be equipped with a reducer with a large output torque and a high power motor. If the starting torque of the spur gear slew drive is small, a small reducer and a small motor are sufficient. So under what working conditions the starting torque of the spur gear slew drive is large and under what working conditions the starting torque of the spur gear slew drive is small?

This requires a comprehensive evaluation based on scientific calculations combined with the actual measured values of the loading experiment, as well as factors such as choosing different safety factors for different applications to obtain a scientific starting torque value.

The starting torque of the spur gear slew drive is directly related to the size of the spur gear slew drive, the clearance of the spur gear slew drive, the tightness of the seal of the spur gear slew drive housing, the actual load of the spur gear slew drive, whether the spur gear slew drive is bear tilting force, etc. Through repeated calculations and actual measurements, Unique Transmission has analyzed and compared scientifically, has scientifically summarized the calculation method of the spur gear slew drive starting torque suitable for its own products, which provides great convenience for customers to design the whole machine.

If you also need to know the starting torque or selecting suitable reducer motor when designing, please contact Unique Transmission, the engineers of the Unique Transmission will provide professional help for you.
