2126 INVOLUTE SP LINESSPLINES AND SERRATIONSA splined shaft is one having a series of parallel keys formed integrally with the shaft andmating with corresponding grooves cut in a hub or fitting; this arrangement is in contrast toa shaft having a series of keys or feathers fitted into slots cut into the shaft. The latter con- struction weakens the shaft to a considerable degree because of the slots cut into it and con-sequently, reduces its torque-transmitting shafts are most generally used in three types of applications: 1) for couplingshafts when relatively heavy torques are to be transmitted without slippage; 2) for trans-mitting power to slidably-mounted or permanently-fixed gears, pulleys, and other rotatingmembers; and 3) for attaching parts that may require removal for indexing or change inangular having straight-sided teeth have been used in many applications (see SAE Paral-lel Side SPLINES for Soft Broached Holes in Fittings); however, the use of SPLINES with teethof involute profile has steadily increased since 1) involute spline couplings have greatertorque-transmitting capacity than any other type.
