About product

A worm gearbox for winch is a type of gear reducer specifically designed for winch applications. It consists of several essential components, including a worm gear, worm, shaft, bearings, housing, and various accessories. The gearbox can be divided into three main parts: the housing, worm gear, and shaft with bearings.

  • Integrated Housing
  • Housing Types
  • Input Shaft Options
  • Output Shaft Variations
  • Shaft Orientation
  • Multiple Reducers Combination

Additional information

Input Power

Gear Ratio

1/10~1/60(single stage)

Product Detail

The housing serves as the foundation for all the components, providing support and stability for the shaft assembly. It ensures the proper alignment of the transmission parts and bears the load applied to the reducer. The worm gear and worm are crucial for transmitting motion and power between two intersecting shafts.

Various accessories are associated with the worm gear reducer. These include the oil cap/ventilator, which releases gas from the gearbox, and the end cover, consisting of a large and small cover that fixes the axial position of the shaft assembly and withstands axial loads. Bearing covers seal the ends of the bearing holes. The oil seal prevents lubricating oil leakage and extends its usage time. The drain plug allows for the drainage and cleaning of used oil during oil replacement. The oil level cap/oil level indicator enables observation of the oil level inside the gearbox.

Features Of Worm Gearbox For Winch

The features of a worm gearbox for winch include:

  • Integrated Housing: The gearbox is built with a sturdy and aesthetically pleasing integrated housing structure, providing excellent rigidity and durability.
  • Housing Types: There are different housing types available, including basic types with vertical or horizontal baseplates and universal types with a rectangular housing. Universal types often have multiple fixed screw holes and can be used with or without a baseplate, offering flexibility in installation.
  • Input Shaft Options: The gearbox allows for various input shaft configurations. It can have a single input shaft or a double input shaft arrangement. Additionally, it can be designed to connect with a motor flange, simplifying the motor integration process.
  • Output Shaft Variations: The output shaft structure of the gearbox offers versatility. It can have a single output shaft or a double output shaft configuration. There is also an option for a hollow output shaft, which can be advantageous for specific winch applications.
  • Shaft Orientation: The orientation of the input and output shafts can be customized according to the specific requirements of the winch system. The input shaft can be positioned upward or downward, and the same flexibility applies to the output shaft.
  • Multiple Reducers Combination: For applications that require a high transmission ratio, multiple worm gearboxes can be combined in series. This allows for achieving the desired reduction ratio while maintaining the compactness and efficiency of the overall winch system.
