Abstract
670,397. Turning-gear. BENDIX AVIATION CORPORATION. Jan. 25,1950 [April 25, 1949], No. 2007/50. Addition to 665,242. Class 7(v) In an improvement in, or modification of, the engine starter gear claimed in the parent Specification there is provided yielding means, such as compression springs 25, for normally holding the overrunning clutch 21, 22 out of engagement, and a friction coupling, for example, shoes 36 and flange 44, between the driving overrunning clutch member 19 and the pinion 2, the friction coupling being adapted to be released in response to rotation of the pinion 2 above a predetermined speed. Upon manual or electromagnetic shifting of the fork 11 the pinion 2 is moved into mesh with the engine gear 3. Rotation of the power shaft 1 is transmitted to a barrel 12 by means of a sleeve 4 splined to the power shaft, the outer end of the sleeve being formed as a flange 9 with radial lugs 14 that engage slots 13 in the barrel 12, which slots also house radial lugs 31 on the driving coupling member 29. The latter has teeth 34 which engage similar teeth 35 on one side of the driving clutch member 19, whilst teeth 21 on the other side of member 19 are normally held by springs 25 out of engagement with teeth 22 of an element 17 secured to the pinion 2; teeth 34 and 35 form an overload coupling. Due to engagement of pinion 2 and engine gear 3, rotation of member 29 causes teeth 34 to cam the clutch member 19 rightwardly by interaction with teeth 35, and so engage the overrunning clutch, the member 19 being held against rotation by the centrifugal friction coupling, the shoes 36 of which frictionally engage the flange 44 on member 19. When the axial movement of member 19 is arrested by a thrust washer 18 interposed between member 17 and the inturned part 16 of the barrel 12, further camming action between teeth 34 and 35 takes place by backward movement of member 29 against its disc loading springs 33 so that torque is transmitted through the overload coupling and overrunning clutch to crank the engine. When the engine starts, the teeth 21 and 22 are cammed out of mesh and the shoes 36 lift to enable the pinion 2 to rotate freely. In a modification, the frictional surfaces of the shoes and flange are tapered.
