Constant-velocity joint. A constant-velocity joint (also called a CV joint and homokinetic joint) is a mechanical coupling which allows the shafts to rotate freely (without an appreciable increase in friction or backlash) and compensates for the angle between the two shafts, within a certain range, to maintain the same velocity.
Hirth joint. Face spline joints consist of a ring of radial splines or teeth milled or ground into the end faces of two rotary components such as a drive shaft and the hub of a wheel. The angle between the flanks of each spline is usually either 60° or 90°. The two components with matching splines are held together by a bolt through the middle.
A universal joint. A universal joint (also called a universal coupling or U-joint) is a joint or coupling connecting rigid shafts whose axes are inclined to each other. It is commonly used in shafts that transmit rotary motion. It consists of a pair of hinges located close together, oriented at 90° to each other, connected by a cross shaft.
A Schmidt coupling is a type of coupling designed to accommodate large radial displacement between two shafts. Consisting of an arrangement of links and discs—three discs rotating in unison, interconnected in series by three or more links between each pair of discs—a Schmidt coupling can adapt to very wide variations in radial displacement while running under load.
A gear coupling. A gear coupling is a mechanical device for transmitting torque between two shafts that are not collinear. It consists of a flexible joint fixed to each shaft. The two joints are connected by a third shaft, called the spindle. Each joint consists of a 1:1 gear ratio internal/external gear pair.
The original 12-foot skeleton retailed for $399, but not only does the newer version have upgraded eyes, it also has a lower price tag of $299, making it slightly more affordable. Overall, I think ...
A spline is a ridge or tooth [1][2][3] on a drive shaft that matches with a groove in a mating piece and transfers torque to it, maintaining the angular correspondence between them. For instance, a gear mounted on a shaft might use a male spline on the shaft that matches the female spline on the gear. Adjacent images in the section below show a ...
