The spur wheel K 31015 is a critical gear component mounted on the crankshaft of the Sulzer ZV40/48 engine, responsible for transmitting rotational motion to associated engine systems with high precision. Designed with accurately machined teeth geometry, it ensures smooth meshing, efficient power transfer, and minimal noise and vibration during operation. Operating under high loads, continuous rotation, and varying thermal conditions, this gear is manufactured from high-strength, wear-resistant materials to guarantee long-term durability and dimensional stability. Proper alignment and surface finishing further enhance its operational reliability. By enabling synchronized motion within the engine’s mechanical systems, the K 31015 spur wheel plays a vital role in maintaining timing accuracy, mechanical efficiency, and overall engine performance.
