Output shaft
The cold forging output shaft is a high-precision spline component manufactured from 20CrMoM steel, engineered for reliable power transmission in various mechanical applications. This component features a durable construction with a precisely formed internal interface created through cold forging, which enhances strength, dimensional stability, and load-carrying capacity. The exterior includes two external splines produced via spline rolling in a single process, increasing its durability and ability to withstand high torsional loads. Additional machining methods such as turning, milling, and grinding are utilized to achieve strict dimensional tolerances and surface finish requirements.
Manufacturing involves two heat treatments: initial quenching and tempering to attain approximately 290 HV30 hardness, which improves toughness and resistance to wear; followed by induction heat treatment in select areas, reaching a minimum hardness of HV400. This dual heat treatment process enhances surface hardness and fatigue strength, extending service life. Dimensional control is rigorous, with outer diameters maintained within 7 microns and inner diameters within 13 microns to ensure precise fit during assembly. Laser marking with a 2D barcode provides traceability, facilitating quality control and tracking of each component.
This cold forging output shaft is well-suited for use in automotive transmissions, heavy machinery, and industrial equipment where high strength, accurate dimensions, and traceability are critical. It is especially suitable for OEMs and remanufacturers seeking durable spline components that can operate reliably under demanding conditions. The product is supplied as a finished component, with no additional hardware included.
Care instructions include regular inspection for surface wear and dimensional integrity. Cleaning can be performed with standard metal degreasers. To prevent corrosion, store the component in a dry environment. The manufacturer provides a warranty against manufacturing defects, ensuring long-term serviceability and consistent performance in critical applications.
