Products Description
The Main drive shaft of pipe jacking machine is a crucial component that transmits power to the tunneling head. It consists of a power motor, small gear, and large gear. The motor is fixed to the rear box, and the small gear is mounted on the front and rear boxes. Through involute gear transmission, it drives the large gear and main shaft to rotate. This structure is compact with high power density, facilitating multi - cutterhead arrangement and suiting different pipe - jacking machine interfaces.
Features
1. The Main drive shaft of pipe jacking machine is made of high - strength alloy steel, with chromium enhancing corrosion resistance and molybdenum increasing strength and toughness. After quenching and tempering, its properties are strengthened to handle complex working conditions.
2. The Main drive shaft of pipe jacking machine is stepped, fitting components well and reducing stress concentration with processed fillets. High - precision keyways cooperate with connectors for efficient power transmission.
4. The Main drive shaft of pipe jacking machine is often hard - chrome - plated to resist soil scratches. Some high - end products use ceramic coatings to enhance durability, reduce maintenance, and strengthen wear resistance.
5. High - precision equipment is used for the dynamic balance of the Main drive shaft of pipe jacking machine, strictly controlling the unbalance to ensure high - speed stability, reducing noise and impact, and ensuring construction safety and accuracy.
Application
The Main drive shaft of pipe jacking machine is central to underground pipeline laying. When the motor starts, power is transmitted through high - precision keyways to the cutterhead, which rotates at a preset speed to cut soil. With high - strength material and fine structure, the shaft bears axial force and torque, coordinating with seals and bearings to steadily push the pipe - jacking machine for trenchless pipeline laying.
