Abstract
A speed reducing device for a carriage includes: a base fixed to a carriage body; a carrier fixed to the base; a case to which a wheel is detachably attached; a reducer that is supported by the carrier, decelerates power input thereto, and transmits the power to the case to rotate the case; and a flange fixed to the base or the carriage body and separately provided from the carrier. The flange supports a brake unit that is for braking the power input to the reducer.
Claims7
A speed reducing device for a carriage, comprising:
- a base fixed to a carriage body;
- a carrier fixed to the base;
- a case to which a wheel is detachably attached;
- a reducer supported by the carrier, the reducer decelerating power input thereto and transmitting the power to the case to rotate the case;
- and
- a flange fixed to the base or the carriage body and separately provided from the carrier, the flange supporting a brake unit that is for braking the power input to the reducer,
- wherein the flange is provided such that the flange is not connected to the case.
4 more elements
A driving device for a carriage, comprising:
- a speed reducing device supported by a carriage body, the speed reducing device reducing a speed of rotation input thereto and outputting the rotation from an output element;
- a wheel detachably attached to the output element of the speed reducing device;
- a flange directly or indirectly supported by the carriage body;
- and
- a brake unit retained by the flange for braking the wheel,
- wherein the brake unit and the wheel are detachable from the output element by moving the brake unit and the wheel toward one side along a rotation axis of the output element while the speed reducing device is retained on the output element.
