Long Service Life 20CrMnTi Drive Shaft For Mechanical Drive Systems

Long Service Life 20CrMnTi Drive Shaft For Mechanical Drive Systems

Drive shaft is a core power transmission component in mechanical drive systems, mainly composed of shaft body, universal joint, splined shaft, telescopic sleeve, flange plate and balance weight. It connects transmission parts with different axes, angular deviation and axial displacement, realizing flexible long-distance power transmission, and compensating installation deviation, angle offset and axial expansion. Made of high-strength alloy steel with precision forging and finishing, it features high torque, high rigidity, fatigue resistance and excellent dynamic balance. Widely used in automobiles, construction machinery, agricultural machinery, industrial equipment, ships and new energy vehicles.

Product Features

• Adaptable to angular deviation and axial expansion between two shafts with strong transmission compatibility.
• Integral forged structure with high strength and toughness, able to withstand high torque impact load.
• High-precision dynamic balance treatment with low vibration and low noise at high speed.

Cautions

• Over-torque and over-speed overload operation are strictly prohibited to avoid shaft torsion and fracture.
• Forced installation under severe axial deviation is forbidden to prevent early damage from excessive additional stress.
• Lubricate splines and universal joints regularly; dry running without grease is prohibited.
• Do not strike shaft and flange heavily during installation to avoid deformation and precision deviation.
• Keep transmission parts sealed and dustproof to prevent abrasive wear caused by sediment impurities.
• Operating temperature shall not exceed rated range to avoid metal fatigue and material performance degradation.
• Stop immediately for maintenance when abnormal vibration, noise or overheating occurs.
• Replace the whole drive shaft integrally when shaft cracks, severe spline wear or excessive universal joint clearance appears.
• Avoid continuous heavy impact load to reduce fatigue damage of shaft.
• Store in dry and ventilated environment with anti-rust treatment to prevent oxidation and corrosion.
