Description

Triangular Seamless Steel Pipe and Tube for PTO Shaft is a type of special-shaped steel pipe. The full name of PTO shaft is “Power Take Off”, which is an important part of agricultural machinery. The main function of Triangular Seamless Steel Pipe and Tube for PTO Shaft is to transmit the power output of the tiller engine to the tilling implements, driving the tilling implements to perform operations such as turning the soil, loosening the soil, and sowing.

Triangular Seamless Steel Pipe and Tube for PTO Shaft is one of the shafts behind the tiller. It connects the tiller and the tilling implements to enable the tilling implements to have power and complete the tilling operation.

Triangular Seamless Steel Pipe and Tube for PTO Shaft can adjust the speed and output power according to the requirements of different tilling implements, so that the tiller can adapt to different operation requirements. In addition, PTO shaft can realize mechanized tillage, improve production efficiency, reduce the labor intensity of tillage, and better meet the needs of modern agriculture.

Features of Triangular Seamless Steel Pipe and Tube for PTO Shaft:

Triangular Seamless Steel Pipe and Tube for PTO Shaft are seamless steel tubes with a triangular cross-section used in power take-off (PTO) drive shafts. Their core features are: non-circular cross-section, seamless structure, high torsional strength, and compatibility with spline connections.

1. Non-circular cross-section (triangular/trilobal spline): Enables efficient torque transmission and prevents relative rotation. Often used in conjunction with splines for agricultural machinery PTO drive shafts.

2. Seamless manufacturing process: Triangular Seamless Steel Pipe and Tube for PTO Shaft uses hot-rolled or cold-drawn seamless steel tube blanks, which are subsequently formed (such as rolling or broaching) into a triangular cross-section. This maintains the seamless tube’s characteristics of “no weld seams, uniform structure, and resistance to high pressure/high torsion,” but the final product is a “formed shaft tube.”

3. Materials and properties: Mostly 16Mn (Q345), 45 or alloy steel, with a yield strength ≥350MPa. Heat treatment ensures fatigue resistance and high torsional stiffness, suitable for tractor PTO shafts (typically operating at 540/1000 rpm).
