Kind Code:
B2
Abstract:
PURPOSE: To reduce weight and size of a power transmitting device of a planetary roller type wherein holes for fastening an inner roller is located within a periphery of the inner roller, so that the outer diametrical dimensions of a casing and a case cover may be reduced down to about the outer diametrical dimension of the inner roller.
CONSTITUTION: A sun roller 2 is connected to the end of an input shaft 1, while, a carrier 4 is connected to the end of an output shaft 3, so that respective planetary rollers 7 may be supported on planetary pins 5 inserted to the carrier 4. Screw holes 8b for fixing an inner roller 9 are provided to the flange 8a of a casing 8, while bolt setting holes 13a are provided at the locations corresponding to those of the screw holes 8b. Further, bolt setting holes 23a of a spacer wheel 23, which is inserted into a groove 9m of the inner roller 9, are provided at the locations corresponding to the bolt setting holes of the inner roller 9. Then, the inner rollers 9 are inserted with packings 14 applied on both side surfaces of the spacer wheel 23 so as to contact with the outer surfaces of the planetary rollers, thereafter a case cover 13 is integrally fastened onto the spacer wheel 23.
