High‑Strength C45 Steel Drive Shaft With DIN5482 External Involute Spline TR80×16 Power Screw For Heavy‑Duty Winch Transmission

1.Description

This heavy‑duty drive shaft (Part No.476591) is manufactured from C45 carbon steel, designed with TR80×16 power screw thread and DIN5482 B40×36 external involute spline. Strictly follow NS‑ISO 2768‑mK general tolerance standard, surface roughness Ra3.2. Precision machined for winch & mechanical power transmission systems. Weight calculated 94kg, each dimension & spline parameter is fully inspected to guarantee stable torque output under heavy‑load working conditions.

3.Advantage

1. High‑quality C45 carbon steel blank, excellent tensile strength and torsion resistance. It can bear large cyclic torque under heavy‑load marine and industrial working conditions, resist deformation and fracture during long‑time continuous operation.
2. DIN5482 standard grade‑9 external involute spline. Even tooth‑profile load distribution, small transmission backlash, stable torque transfer. Complete spline inspection report is available for each batch, all spline dimension including pin‑over measurement value can be traced.
3. TR80×16 trapezoidal power screw thread. Good wear‑resistance, can realize rotary‑to‑linear compound motion, reliable for power‑screw‑type winch drive mechanism.
4. Strictly follow NS‑ISO 2768‑mK tolerance specification and Ra3.2 surface finish. Lower friction coefficient, reduce component abrasion during reciprocating movement, greatly extend service life of mating parts.
5. Strict multi‑step in‑house quality control. We inspect thread dimension, spline parameter, surface quality and overall shaft straightness before shipment. We accept custom modification based on original drawing, capable to copy non‑standard overseas shaft spare parts.
6. Specially optimized structure for marine offshore hoisting equipment, compatible with Lebus double‑folded drum winch system, good adaptability for harsh site environment.

4.Applicaton

This C45 drive shaft serves as core power transmission spare part, widely used for marine deck winch, offshore platform hoisting winch, industrial heavy‑duty winch, Lebus double‑folded rope‑groove drum winch, lifting & hoisting machinery, power‑screw‑driven actuator equipment.
It fits various heavy‑duty industrial scenarios including ship‑deck operation, offshore engineering project, port lifting equipment, heavy‑duty material handling machinery. Suitable as replacement spare part for original Evotec winch transmission system, also available for new‑project mechanical transmission assembly.
