kardaanijärjestelmiä

Kardaanijärjestelmiä, often referred to as a universal joint or U-joint, is a mechanical coupling that connects rotating shafts that are not in alignment. Its primary function is to transmit rotational power between shafts whose axes are at an angle to each other. This allows for flexibility in mechanical designs where rigid connections are not feasible due to movement or misalignment. The most common type of kardaanijärjestelmiä consists of two U-shaped yokes attached to the ends of the shafts and a cross-shaped piece, known as a spider, that pivots within the yokes. This structure enables the joint to accommodate angular misalignment. Kardaanijärjestelmiä are widely used in automotive drivetrains to connect the transmission to the differential, allowing for suspension movement and steering. They are also found in industrial machinery, agricultural equipment, and various other applications where power needs to be transmitted through angled or moving shafts. The design and size of kardaanijärjestelmiä vary depending on the torque and speed requirements of the application. Maintenance typically involves lubrication to ensure smooth operation and prevent wear.
