Crank Shaft
Globagon manufactures custom crankshafts for reciprocating compressors, based on customer-defined specifications, load requirements, and material standards.
Each crankshaft is machined for maximum torsional strength, dimensional precision, and dynamic balance—ensuring smooth power transmission and long-term mechanical reliability under cyclic loading. Designs can be configured to suit various frame types, stroke lengths, and lubrication systems.
Using advanced manufacturing processes and thorough quality inspection, Globagon delivers crankshafts that meet the mechanical and performance demands of high-duty compressor applications.
Working Principle
Crank Shaft
In larger reciprocating compressors, forged steel crankshafts are widely used due to their superior strength, fatigue resistance, and long-term durability under high mechanical loads. For smaller units rated at 150 kW or below, ductile iron crankshafts are often a more economical choice, offering sufficient performance for moderate-duty applications.
To ensure stable and efficient operation, crankshafts are typically equipped with removable balance weights. These weights are essential for correcting both rotational and reciprocating imbalances, reducing stress on other components. For compressors operating at speeds above 800 RPM, dynamic balancing of the crankshaft becomes critical. It helps minimize vibration, enhances reliability, and extends the service life of the entire machine.
