VE/PE series slew drive for solar tracker

Product catalog summary

1. Overview

This document details technical specifications, performance parameters, and design considerations for a range of slewing drives, including both active and passive types. These drives provide rotational motion control with integrated gear reduction and torque transmission, suitable for high-precision applications.

2. General Specifications

Units: Dimensions are in millimeters (mm), with 1 inch = 25.4 mm.
Weight Range: Models weigh between 33 kg and 90 kg.
Precision Tracking: All models maintain positional accuracy within ≤ 0.3°.
Output Shaft Types: Available in square or octagonal profiles; customizable per customer needs.
Protection Class: Motor units have an IP65 rating, ensuring dust-tight and water-resistant operation.

3. Performance Parameters by Model

The slewing drives cover a broad range of torque and gear ratio options. Key parameters include:

Holding Torque: From 15 kN·m up to 55 kN·m.
Rated Output Torque: Between 2.5 kN·m and 5.5 kN·m.
Maximum Output Torque: Up to 11.5 kN·m.
Gear Ratios: Wide range from 50:1 to over 500:1, enabling tailored speed and torque outputs.
Weight: Varies by model from 33 kg to 90 kg.
Output Shaft Dimensions: Square shafts range approximately from 110×110 mm to 154×154 mm; octagonal shafts around 226×158 mm.

4. Mechanical Features

Hard Stop: Integrated mechanical limiters prevent over-rotation, typically limiting angular movement to about 3°–4°.
Grease Plug: Standard M10×1 plugs facilitate lubrication maintenance.
Mounting: Multiple M10 tapped holes evenly spaced for secure installation.
Output Shaft Tolerances: Detailed dimensional tolerances ensure proper fit and function.

5. Motor Integration (Active Drives)

24 VDC brushed planetary reducer motors are used, with rated torque ranging from 43 N·m to 550 N·m depending on model.
Rated speeds vary between 1 rpm and 9.5 rpm.
IP65 protection rating ensures durability in harsh environments.
One motor can drive multiple slewing drives simultaneously (e.g., two or three units).

6. Customization and Design Notes

Output shaft types and sizes can be customized to meet specific customer requirements.
Drawings and specifications are for reference and subject to change without notice due to ongoing product improvements.
The manufacturer reserves the right to modify designs to enhance performance or reliability.

7. Summary of Critical Parameters

Torque Range: Holding torque from 15 kN·m to 75 kN·m; rated torque up to 8.5 kN·m; max output torque up to 18 kN·m in larger models.
Gear Ratios: From 50:1 up to 750:1, allowing for diverse application needs.
Precision: Consistent tracking accuracy ≤ 0.3° across all models.
Weight: Approximately 33 kg to 90 kg depending on model and configuration.

8. Visual and Dimensional Data

Each model includes detailed top, side, and front views with dimensional annotations covering shaft sizes, hole patterns, and mechanical stop locations to ensure proper integration into customer systems.

9. Recommendations and Best Practices

Regular lubrication through grease plugs is essential for optimal performance and longevity.
Verify shaft dimensions and tolerances prior to installation to ensure compatibility.
Select gear ratios and torque ratings carefully to match application requirements.
Use IP65 rated motors for environments requiring dust and water resistance.
Consult the manufacturer for custom designs to meet specific application needs.
Ensure mechanical hard stops are correctly installed to prevent damage from over-rotation.
Account for weight and size in system integration planning.

Note: All technical data and drawings are subject to change without prior notice as part of continuous product improvement efforts.
