Abstract

PURPOSE: To realize a device of smaller and lighter type without changing the speed reduction ratio and lowering the torque of output by fitting with a play, the inside of a pinion in the central part of a support block in a reduction gear, by making effective use of the inside of the pinion.
CONSTITUTION: A support block 11 in this reduction gear consists of a block body 1 and a marginal disc 9, out of which the block body 1 has a connection part 7 composed of connection-plate parts 3, for instance, of three, extending in the radial direction with an interval of an equal angle and projecting in the axial direction to form the part 7. On the other hand, a pinion 12 has a piercing hole 13 similar in shape to the profile of the connection part 7, which is fitted with a play, in the hole 13. In addition, the pinion 12 has an insertion hole 14 between the parts of the piercing hole 13, and the eccentric large-diameter part 30 of a crank pin 27 is fitted in the insertion hole 14 in a rotation-free way. The small-diameter part 29 of the crank pin 27 is fitted to outer gears 38, in plural number, provided so as to be faced with a disc body 36, and the outer gears 38 are engaged with the outer teeth 22 of an input axis 17.
