Võllidega

Võllidega refers to mechanical systems or assemblies that utilize shafts (võllid) as central elements to transmit torque and rotational motion between components. In engineering, võllid serve as the core members that connect power sources, such as engines or motors, to driven parts like gears, pulleys, couplings, or wheels. The term is used to describe both individual shafts and complete transmissions or drivetrains where shafts form the main axis of rotation.

A shaft is designed to resist torsion, bending, and shear while operating at high speeds. Important design considerations include material selection (commonly steel alloys), diameter, surface finish, and the presence of features for torque transmission such as keyways or splines. Shafts are typically supported by bearings and may be balanced to minimize vibrations. Tolerances and runout affect gear alignment, efficiency, and lifespan. In many systems, hollow or stepped shafts are used to optimize strength-to-weight ratios and to route other components or cables.

Common applications include crankshafts in internal combustion engines, propshafts in drive trains, intermediate or input shafts in gearboxes, and precision shafts in machine tools or CNC equipment. Depending on the application, shafts may incorporate features such as lubrication channels, coatings, or surface hardening to extend service life.

Maintenance of systems with võllidega focuses on bearing condition, alignment, lubrication, and inspection for wear, corrosion, or fatigue. Proper design and upkeep are essential for reliability and efficiency in mechanical power transmission.
