Product Overview
This series of gerotor/orbital motors, tailor-made for agricultural machinery, with their classic four-bolt mounting flange, robust parallel key output shaft, and mature gerotor gear pair design, serve as the ideal power source for driving the rotating mechanisms of various medium-sized agricultural equipment. With high cost performance, excellent low-speed stability, and strong anti-pollution capability, they provide reliable power for processes such as sowing, fertilizing, irrigating, and harvesting.
Core Features
• Agricultural-specific design: Structurally reinforced with a higher dust and water resistance rating, suitable for harsh working conditions in the field such as heavy dust, humidity, and vibration.
• Standard mechanical interface: Adopts a universal four-bolt mounting flange and a splined output shaft, which directly matches most agricultural machinery transmission systems, making installation and replacement simple.
• Cycloid technology core: Built-in high-efficiency cycloid gear pair (planetary meshing mechanism) provides high starting torque and extremely low stable speed, very suitable for direct drive without a gearbox.
• Sturdy and durable: The housing is robust, and key moving parts are heat-treated to ensure long service life and reliability under impact loads.
Main application scenarios
This series of motors are widely used to drive the working devices of the following agricultural machinery:
• Sowing and fertilizing machinery: driving seed meters, fertilizer dispensers, and fans.
• Plant protection machinery: driving spray boom folding mechanisms, pesticide pumps, and mixers.
• Irrigation equipment: driving the traveling wheels of reel-type sprinklers and pointer-type sprinklers.
• Harvesting machinery: driving the ear picking rollers of corn harvesters, the side output shafts of straw returning machines, and the augers of small harvesting platforms.
• Tillage machinery: driving the deflection angle adjustment mechanism of disc harrows and the height adjustment of ridgers.
• Livestock machinery: driving the discharge augers and conveyor belts of feed mixing trucks.
