Slew Drive for Solar Tracking System
This slew drive for solar tracking system adopts envelope worm technology, providing tracking accuracy of up to 0.1 and strong static locking ability, ensuring that the photovoltaic bracket can maximize the power generation income within the whole life cycle of 25 years, and has sufficient supply of goods to support batch mining.
Important parameters of Slew Drive for Solar Tracking System
Slew Drive for Solar Tracking System Characteristics
Reduce power loss
Using multi-tooth contact envelope worm drive, backlash control between 0.05 ° and 0.1 °, compared with the traditional gear to improve more than 3% of the power station tracking efficiency, reduce the power loss caused by alignment error.
Resist the instantaneous wind of 45 m/s
The static overturning moment bearing capacity reaches 135kN.m, which can resist the instantaneous wind of 45 m/s, lock the photovoltaic panel posture in extreme weather, and avoid the vibration or damage of the bracket structure.
Industrial-grade anti-corrosion performance
The shell has been hot-dip galvanized and specially sprayed, and passed the 1000-hour neutral salt spray test to ensure that structural corrosion does not occur for 25 years in coastal high salt spray and high humidity environments.
Reduce mechanical wear
The double lip skeleton oil seal is used to effectively prevent small sand, dust and water vapor from entering the shell in the desert area, prolong the service life of the internal grease by 50%, and reduce mechanical wear.
Low maintenance operation design
Internal pre-filled extreme pressure long-term grease, in the standard operating environment can achieve 5-8 years maintenance-free, greatly reducing the remote large-scale photovoltaic power plant inspection and operation and maintenance costs.
Standard modular interface
Provide universal motor flange interface, which can be seamlessly adapted to mainstream DC motors or stepping motors, simplify the installation process by 30%, and significantly improve the construction progress of EPC project site.

Slew Drive for Solar Tracking System Comparison Points
Through the design of double envelope transmission and the optimization of sealing material, the product significantly improves the operation stability and fatigue resistance, and effectively solves the problem of oil leakage under extreme temperature difference.
Solve The Pain Point Of Bracket Resonance Torsion
Aiming at the pain point of large wind-affected area of 600W + large-size components, this product effectively prevents the risk of bracket resonance torsion caused by strong wind by improving torque rigidity.
Solve The Pain Point Of The Abnormal Wear And Jam Of The Internal Gear Pair
For the problem of sand and dust erosion in remote sites such as deserts and Gobi, the high protection level sealing technology solves the abnormal wear and jam of the internal gear pair caused by the entry of wind and sand.
Solve The Pain Point Of The Precision Drift Caused By Long-term Operation
The use of high hardness alloy steel and induction hardening treatment, the tooth surface hardness of HRC55-62, to solve the low-end products due to long-term operation of the tooth surface wear caused by the increase of backlash.

Our factory
This product is designed with reference to the maximum wind load 1 50 years, and with the system locking mechanism, it can withstand instantaneous wind speed above 45 m/s (above level 14) under static state.
Through the use of 42CrMo high-strength alloy steel material, shell anti-corrosion coating and high-performance seals, combined with regular lubrication maintenance, can meet the photovoltaic industry’s 25-year life cycle standards.
Support. Our SE Series features an enclosed housing with an internal axial load-bearing design optimized for both horizontal and oblique single-axis tracking systems.
Due to the high hardness tooth surface treatment and envelope technology, the wear rate is extremely low. Under normal load, the backlash increase in the first 10 years is usually controlled within 20% of the initial value.
The standard product is IP66, which completely prevents dust from entering and resists strong water spray. If the project is located in a frequently waterlogged or extremely humid area, a reinforced sealed version with IP67 rating can be customized.
You can. In addition to the commonly used 62:1 and 78:1, we can customize the internal worm module according to the customer’s motor speed and torque output requirements.
