Forged Gear 40Cr Keyway Bore For Lifting Equipment

Forged Gear 40Cr Keyway Bore For Lifting Equipment

Product Description

This gear is forged from 40Cr steel and quenched-and-tempered to obtain excellent comprehensive mechanical properties. With high-precision tooth profile machining, it delivers stable transmission and strong impact load-bearing capacity. Designed for transmission mechanisms of lifting equipment, it can withstand alternating loads under heavy‑duty working conditions. It is suitable for fixed cranes and various other lifting machinery.

Technical Parameter

Advantages

1. Forged 40Cr steel with quenching & tempering treatment, combining high strength and toughness, good impact resistance for alternating heavy‑load lifting conditions.
2. Precisely machined gear teeth ensure smooth transmission, low meshing noise and high transmission efficiency.
3. High‑accuracy tooth surface provides good wear resistance, extending service life and reducing equipment failure risks.
4. Specially designed for lifting equipment, compatible with fixed crane transmission systems with good interchangeability.

Matters Need to Attention

1. Inspect gear tooth surface before assembly. No dents, cracks or burrs are allowed, and mating surfaces shall be kept clean.
2. Control meshing clearance and alignment accuracy to prevent partial tooth wear or tooth breakage caused by offset load.
3. Ensure sufficient lubrication during operation, regularly check lubricant condition to avoid dry friction accelerating tooth damage.
4. Over‑load operation and impact overload are prohibited. Regularly inspect tooth wear and cracks for timely maintenance or replacement.
