Analysis of lightweight double gear slew drive solutions

Core Design Advantages

In response to the core demands of limited installation space for automated rotating platforms, high requirements for lightweight design, strict requirements for repeat positioning accuracy, and severe control of end face runout, the design engineers at U-TRSM have specially developed this slew drive, incorporating multiple innovative designs to meet the customer’s operational requirements.

Key structural design

1. Transmission system optimization

Internal gear dual input design: significantly enhances output torque within limited installation space, the dual gear layout simultaneously achieves mechanical backlash elimination, effectively ensuring transmission accuracy.

High precision gear grinding process: gears are ground to grade 6 precision to make the transmission process smoother, and the backlash can be controlled to less than 3′.

2. Load capacity and stability design

Crossed roller structure: significantly enhances the equipment’s axial/ radial load capacity, combined with precision assembly techniques, the axial/ radial clearance is controlled to <0.04mm, with end face runout <0.02mm, ensuring stable operation of the rotating platform.

Mounting surface precision machining: the mounting surface uses grinding process, the surface roughness can reach 0.8μm, which improves the mounting precision and the equipment overall rigidity.

3. Lightweight and durable design

Aluminium alloy housing application: high-strength aluminium alloy is chosen as the housing material, which significantly reduces the overall weight under the same size and achieves the goal of lightweight. The surface is treated by anodic oxidation, which takes into account the aesthetics and corrosion resistance, and prolongs the service life of the equipment.

Gear quick release design: for the gears are easy to wear, we designed a convenient disassembly structure, when the gears are worn or damaged can be quickly replaced, reducing maintenance costs and downtime.

Summary of design highlights

Balance of space and performance: the inner tooth design breaks through the space limitation and achieves high torque output in a small size to meet the needs of compact installation.

Balancing precision and weight: the aluminium alloy material achieves lightweight without losing performance, and combined with high precision machining process, it ensures repeatable positioning accuracy and operational stability.

Durability and maintainability: wide-temperature materials are suitable for complex working conditions, and the quick-release structure reduces the difficulty of later maintenance and improves the equipment comprehensive use value.

Through structural innovation and process optimisation, this slew drive is perfectly adapted to the needs of automated rotary platforms in terms of high precision, high stability and light weight, providing customers with reliable transmission solutions.
