Slewing Drive for Wind Turbines

Introduction

Slewing drives are an essential component of wind turbines. They enable the nacelle to rotate and align with the wind direction for maximum energy output. The design of a slewing drive must be precise, reliable, and able to withstand harsh environmental conditions.

How Does a Slewing Drive Work?

A slewing drive is a gearbox that consists of a horizontal or vertical-mounted ring gear and a coaxial pinion that rotates around its axis. The rotation of the pinion causes the ring gear to rotate, which in turn drives the load attached to the outer ring. The design of the slewing drive allows it to handle high axial, radial, and tilting moment loads with high accuracy and efficiency.

Types of Slewing Drives

Single-axis Slewing Drives

Single-axis slewing drives are designed to handle single-axis loads, typically in horizontal or vertical applications. They are commonly used in small wind turbines, solar trackers, and construction machinery.

Dual-axis Slewing Drives

Dual-axis slewing drives are designed to handle two-axis loads, typically in solar trackers and satellite antennas. They can rotate in two perpendicular planes and accurately track the sun’s movement for maximum energy output.

Advantages of Our Slewing Drives

Our slewing drives are designed with planetary gearboxes that provide high torque density, efficiency, and accuracy. They are also sealed to prevent contamination from dust, moisture, and other environmental factors that can cause damage and reduce performance.

Parameter Considerations
Ratio Ratio selection depends on the application requirements, such as torque, speed, and accuracy. The ratio determines the relationship between the input and output speeds and torques.
Input Speed The input speed should be within the specified range to ensure proper operation and prevent damage.
Output Torque The output torque should be sufficient to handle the load requirements and prevent overload and failure.
Backlash Backlash is the clearance between the gear teeth. It affects the accuracy and precision of the gearbox and should be minimized for applications that require high accuracy.
Noise Noise level should be within acceptable limits for the application environment.
Efficiency Efficiency is the ratio of output power to input power and should be high to maximize energy transfer and minimize waste heat.
Operating Temperature The operating temperature range should be within the specified limits to ensure proper lubrication and prevent damage.
Service Life The service life of the gearbox should be sufficient for the application requirements and maintenance schedule.
