Abstract

Provided is an improved clutch unit adapted to be made compactly and to lower the manufacturing cost without spoiling the smoothness of action when the torque transmission is disconnected. In a planetary gear type clutch unit, there is provided with a planetary gear base (16) rotatably supported in co-axial with an outer member (12) and an inner member (11), and rotatably supporting a planetary gear (13); a stopper member (35) moving in and out by means of the action of a solenoid (32) fitted on a member substantially unrotatable; a clutch releasing member (18) rotatably supported by the planetary gear base, and having a protrusion (projecting rib 27) engagable with the stopper member that is being protruded; and a spring member (torsion spring 19) elastically linked and connected between the planetary gear base and the clutch releasing member. With such construction, the engaging force between the planetary gear and the inner member loosens for the flexion of the spring member at the moment the clutch releasing member stops, thereby the disconnection movement of the planetary type clutch unit can be smoothened.

Description of the invention (1) [Detailed description of the invention] [Technical field to which the invention belongs] Install or install remotely; don't be concerned about those who are frightened to install facsimile machines. The ",", and "" cakes perform disconnection-connection clutches that transmit torque. [Previous technology] In fax machines or photocopiers; for 2ΪΠ rotation, stop ▲, and often receive motor rotation ϊ = ΐ Passive ω Between the wheel and the paper-feeding roller, there is a clutch device that is well-known in the history. It will be recognized ~ s ^ f /, the use of the, there will be · fixed and fixed on the drive shaft of the screw Jingqiangwa at the other end The part is wound on the passive shaft. The driving axis of the passive shaft is more momentary because the spiral impulse is wrapped on the passive shaft to convey the torque. The torque of the passive spring is intercepted by the slack of the coil spring. The lap spring-type one-way clutch with the opposite action is constructed to form 1 57 1 28). ',,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, – – –––––––– ## In the clutch device of this type There is a need to increase the size of the entire clutch in the axial direction, and the use of a special spiral bomb with a square cross-sectional shape of the wire rod. The coupling parts of the shaft and the coil spring require higher accuracy, so the & Cost is easy To promote miniaturization and low manufacturing costs, as disclosed in Japanese Patent No. 6 5-2 2 8 6 7, the use of planetary gears can be considered.
