Our company has more than 20 fully automatic high-precision CNC lathes and more than 10 CNC machining centers, and is also equipped with a complete set of professional turning, grinding, milling, drilling, and planing equipment.

Lighter weight and smaller size: These parts weigh less and are smaller in size than equivalent gear reducer systems. Therefore they are more adaptable and produce efficient torque transmitting capability.
Customizable: A reducer system's stages can be layered or altered to create unique configurations that are tailored to the requirements of a particular application. Planetary gear reducers are also simple to use; after being mounted in a cylindrical gearbox, they can be placed absolutely anywhere.
Longevity and robustness: Ball bearings of it help the parts function smoothly and effectively. Due to decreased wear all across the course of their operating life, there will be less product damage and longer product life.

Its construction features a high-strength cast iron or ductile iron housing, large center distance, and oversized bearings to manage extreme loads and shock. The product accommodates powerful motors through input bores up to 28mm and delivers exceptionally high torque via a 35mm output shaft with a 10mm keyway.
Available reduction ratios cover the full spectrum from 5:1 to 100:1, providing the flexibility needed for both speed-sensitive and torque-critical applications.

Types of Speed Reducer
Cyclo reducers: A cyclo reducer, or cycloidal speed reducer, is a specialized gearbox engineered to reduce the speed of an input shaft by a precise ratio while multiplying torque.
Gearbox speed reducer: A gearbox speed reducer, also called a gear reducer, is a mechanical assembly designed to modify the speed and torque characteristics of a power source such as an electric motor.
Gear drives: Gear drives are pre-assembled power transmission systems used for precise speed and torque adjustment in a variety of industrial applications.
In-line gear reducers: In-line gearboxes transmit the rotational speed from a motor to an output shaft arranged parallel (or co-axial) to the motor’s axis.
Planetary gearbox: The planetary gearbox, or epicyclic gearbox, is distinguished by its coaxial (aligned) gear arrangement, featuring a central sun gear, planet gears, and an outer ring gear.
Herringbone gears: Herringbone gears, a special form of double helical gears, combine two sets of opposing helical gear teeth to neutralize axial thrust.
Spur gears: Spur gears are the most basic and widely used type of gear, featuring straight-cut teeth positioned parallel to the gear shaft. Known for simplicity, reliability, and cost-effectiveness, spur gearboxes are ideal for moderate to low-speed applications that do not require extremely high torque.
Helical gears: Helical gears feature angled teeth, enabling more gradual and quiet meshing compared to spur gears.
Right angle gearboxes: Right angle gearboxes, including “t” type speed reducers, feature input and output shafts at a 90-degree orientation.
Worm gear reducers: Worm gear reducers feature orthogonal input and output shafts, with the worm engaged at 90 degrees to the worm wheel.
Application of Speed Reducer
Agriculture
Tractors, harvesters, grain handling equipment for optimal plowing, seeding, and harvesting.
Automotive
Transmissions for smooth gear shifts and better vehicle performance.
Energy
Wind turbines and marine propulsion.
Food processing
Machinery requiring controlled speed and torque for mixing, packaging.
Construction
Cranes, bulldozers, excavators for digging, lifting, and transport.
Robotics
Precise, low-speed, high-torque control for robotic arms and indexing tables.
Components of Speed Reducer
Carcass: External structure that protects and houses the internal components of the reducer.
Axes: Responsible for transmitting the torque from the engine to the gear system.
Gears: Essential components for speed reduction, gears can be of different types such as helical, bevel, planetary, among others. They are responsible for transmitting the movement from the input shaft to the output shaft, reducing speed and increasing torque.
Bearings: Essential for supporting radial and axial loads, ensuring smooth and efficient operation of the gearbox.
Lubrication system: Responsible for ensuring proper lubrication of gears and bearings, reducing wear and increasing the life of the equipment.
Sealing system: Prevents contaminants from entering the interior of the reducer, keeping the internal environment clean and protected.
Input motor: The speed reducer is connected to an input motor that provides the power required for the system to function.
