Slewing drive


  • Fenghe's worm gear and worm rotary drive includes two categories: cylindrical worm and envelope worm, of which cylindrical worm is suitable for medium speed. Heavy-duty applications while the enveloping worm is suitable for low-speed heavy-duty and high-precision applications, the worm gear and worm rotary drive can be self-locking, in the power movement The domain can provide basic security and further simplify the overall design of the equipment, and is an excellent industrial accessory.

  • Rotary drive can be divided into gear drive and worm gear drive according to different transmission forms. It can be divided into two types: open type and closed type. The simplest form of rotary drive is the drive turntable applied to construction machinery products such as excavators and tower cranes. As the last link of the deceleration transmission chain, this rotary drive is open. The front end needs to be equipped with a planetary reducer with a large reduction ratio as its power input, so it can only be called the prototype of the rotary drive. In order to expand the application range of such products and further improve the convenience of product use and maintenance In order to further improve the driving ability of the product, the enveloping worm drive has also been applied to such products. The slewing drive equipped with the enveloping worm not only increases the driving torque, but also The drive accuracy has also been further improved, and digital control is possible, so it is widely used in tracking and fine-tuning devices on solar and wind power generation equipment, in addition to robots, radar, low-speed heavy-duty lifting, lifting equipment, precision CNC turntables and other product fields All have good application effects.

  • (SDE/PDE) The advantages of combined slewing drive systems for horizontal and vertical rotation include precise position control, versatility and adaptability. The horizontal rotation function allows the structure to rotate in a horizontal plane, usually within a 360-degree range, to suit different application needs. This is important for applications that require tracking targets, positioning equipment, or implementing rotating platforms. The vertical rotation function allows the structure to move up and down in the vertical plane, usually within a certain range of angles. This vertical rotation is commonly used in applications such as cameras, telescopes and astronomical observations to observe objects at different heights.

  • A slew drive is essential for solar tracking systems, enabling panels to follow the sun for maximum energy capture. There are several types of slew drives: worm gear, helical gear, and hydraulic. Worm gear drives offer high torque and self-locking capabilities, ideal for single-axis trackers but are less efficient. Helical gear drives are more efficient and quieter, suitable for dual-axis trackers, though they may need additional braking.

  • A slew drive solar tracker is a mechanism that optimizes solar panel orientation to maximize sunlight exposure. It consists of a slewing bearing, a drive mechanism (electric or hydraulic), and a control system with sensors. The tracker adjusts the angle of solar panels throughout the day, increasing energy output compared to fixed systems. There are single-axis and dual-axis trackers, with the latter providing more precise sun tracking. Slew drive solar trackers are used in utility-scale solar farms, commercial installations, and residential systems, offering improved efficiency and energy production, despite higher initial costs and maintenance needs.

  • The SEA/PEA fence frame oil-sealed slewing drive is an industrial machinery reducer for rotating applications, typically used in equipment such as logging machinery. This type of reducer is typically used in applications requiring swing or rotary motion, such as logging machinery. Rotary reducers enable equipment to precisely control rotational motion to position and operate tools. The fence frame is the external structure of the reducer and is usually used to fix and support other mechanical components. It helps ensure that the reducer remains stable during operation. The SEA/PEA fence frame oil-sealed slewing drive is a mechanical component specially used for rotating applications. It ensures the accuracy and reliability of mechanical equipment by decelerating the rotating motion.

  • SE/PE series slewing drives are commonly used in engineering machinery and construction equipment for rotating equipment such as excavators, cranes, rotary drilling rigs, etc. These drives are powered by hydraulic or electric systems to achieve the rotary motion of the equipment. SE series slewing drives generally feature high torque, high load-bearing capacity and stability to meet the needs of heavy machinery. This system provides a high reduction ratio and is suitable for applications requiring high torque and low speed rotation, such as lifting equipment. It provides high precision and helps stabilize rotation and position control. In addition, the worm drive usually does not reverse rotation when it stops rotating and is self-locking, which can be used to prevent the load from sliding or rotating. Widely used in industrial and mechanical applications.

  • The compact and space-saving design of slewing drives is particularly advantageous for solar tracking applications. Their ability to provide high precision and accuracy in panel positioning is crucial for optimizing energy absorption. Additionally, these drives are known for their durability and reliability, as they are constructed with materials that can withstand outdoor environmental conditions, ensuring long-term performance in the field.
