What Is The Gearbox Housing?A Key Component In Rail Vehicle

The gearbox housing of the rail vehicle is a key component in the transmission system of rail vehicles. It is mainly used to support and protect the transmission elements, such as gears and bearings. It ensures that the power is transmitted from the engine to the wheels.

The internal quality of the gearbox shell is high in strength, air tightness and lightweight. Here are its main features and functions:

Main functions

Support and protection: It is used for fixing gears, bearings and other components, preventing external impacts and contamination.

Lubrication and Cooling: It can provide lubrication and heat dissipation, reducing friction and wear.

Power transmission: It plays a vital part in ensuring efficient power transmission and maintaining regular vehicle operation.

Structural Composition

Box body: The body is usually made of cast iron or aluminum alloy, and it possesses high strength and wear resistance.

Gearsets: It is comprised of the driving gear, driven gear, etc., responsible for power transmission.

Bearings: Support gears and shafts, reducing friction.

Sealing device: Prevents leakage of lubricating oil and entry of contaminants.

Lubrication system: Ensure that gears and bearings are adequately lubricated.

Materials and Manufacturing

Materials: The materials are usually cast iron, aluminum alloy or steel. The advantages are high strength, wear resistance and corrosion resistance. 

Manufacturing process: The process involves casting, machining, and heat treatment. It can ensure accuracy and durability.

Maintenance and servicing

Regular inspection: The purpose of the inspection is to monitor the wear condition of gears and bearings.

Lubrication management: It is necessary to replace lubricating oil and keep the lubrication system clean regularly.

Sealing inspection: The purpose of the inspection is to prevent leakage of lubricating oil and intrusion of contaminants.
