Abstract
845,019. Ratchet clutches; shaft coupling. NAPIER & SON Ltd., D. May 9, 1958 [May 20, 1957], No. 15945/57. Class 80 (2). In a ratchet clutch for a helicopter rotor drive a clutch member 10 having inclined facial teeth 12 is helically splined at 16 to a driven shaft 15 and a helical spring 20 connected to the shaft 15 and clutch member 10, urges the latter by compression and torsion into engagement with a facially toothed driving clutch member 11, the mean radius R of the spline connection and the mean radius r of the helical spring being such that R#1+#, where # is Poisson's ratio for the spring, whereby under overrun conditions the resultant spring force on the clutch member 10 is substantially along the splines, reducing frictional resistance at the splines. The ends 22 23 of the coil spring are located in holes in the shaft 15 and in a member 24 adjustably screwed to the clutch member 10 and having a series of spring receiving holes to provide adjustment for the end 22 so that the spring 20 is relaxed when the clutch is engaged. The radius of gyration of the clutch member 10 is approximately equal to the radius of the spline connection.
