Splined Low Speed Output Shaft Free Forging for Industrial Drive Systems
The Splined Low Speed Output Shaft Free Forging for Industrial Drive Systems is a robust forged component designed to transmit high torque at reduced rotational speeds in demanding mechanical environments. Manufactured from high-strength alloy steels such as 42CrMo4, 20CrMnTi, these shafts offer superior fatigue strength, shock resistance, and dimensional stability.
Key Features:
-
Engineered for heavy-load, low-speed torque transmission in gear reducers, mills, and mixers
-
Forged with a ≥ 3.0 forging ratio to ensure optimal grain flow for resistance to torsional and bending stresses
-
Compatible with splined, flanged, stepped, or keyed designs to suit various drive interfaces
-
Heat-treated via quenching + tempering or normalizing, with optional stress relief for enhanced machining precision
-
Subjected to comprehensive ultrasonic and mechanical testing, ensuring internal integrity and consistent performance
-
Available in solid or bored configurations for different transmission setups
Applications:
-
Gearboxes in heavy-duty equipment such as cement kilns, crushers, mixers, rolling mills, and conveyors
-
Low-RPM power transmission shafts in mining, marine, and metallurgical sectors
-
Drive systems requiring high torque stability, long service life, and reliable power delivery
