SDE12" High Torque Slew Drive Gearbox Reducer With NEMA34 For Concentrated Solar Power Station
Description
Our slewing drive is powered with hourglass worm technology for maximum gear torque and the smoothest rotation. Typical slew drive applications include solar industry, truck cranes, man lifts, and utility equipment, hydraulic attachments, oil tool equipment, marine cranes, tire handlers, digger s and automotive lifts, but the slew drives are used in many other applications requiring load holding and rotational capability. We offer different slew drive models with different moment load capacities. The standard slew drives are fitted with an open housing and single self-locking hourglass worm shaft. Once the power source input is returned to neutral, the worm shaft will lock the load into position without requiring any external braking device.
The slew drive can be with worm gear, spur gear, bevel gear. And also for the inside slewing ring, it can be single-row ball slewing ring, and also can be double-row ball slewing ring. The one with double-row can take much more load. It can be chosen depended on your application.
Advantages
1. Precision: less than 0.1 degree
2. Self-locking
3. IP rating: IP66
4. High precision to let the system fully automatic tracking in a higher precision manner
5. To achieve approx 45% more power output than fixed mounting system
6. Easy installation and handling
7. easy maintenance
Dual Axis Slew Drive
The most common slewing drive application for the dual axis slewing drives is dual axis solar trackers. The dual axis tracking system is a kind of power unit that can keep the solar panel facing the sun at any time and make the solar light irradiate the solar panel vertically at any time. Dual axis slew ring drive can improve the tracking precision and power generation efficiency which means the dual axis slew drive are able to create an efficient and reliable solution in a single drive. The dual axis slew drives for CPV can be mounted horizontally, vertically, or on a combination of multiple axes.
How to choose the proper size of slewing drives?
Choosing a proper size of the slewing drives in order to avoid from not only performance lack or performance surplus is play an important role in achieving cost effective solutions.
Please give us the following information in order to select a suitable slewing drive:
1. the application
2. the output toque required. If you do not have a clear idea of that data, just tell us the load, for example, the weight of panels and the mounting brackets on our slewing drive.
3. the load dimensions and the biggest wind in your area in the past 10 years which are used to calculate if the drive we recommended could bear the maxium load when there comes the big wind.
4. the output speed you required which will help us to recommend the suitable motors for you.
5. other informations such as backlash, IP grade demand etc
