Abstract
The utility model discloses a simple clutch device which comprises a rotating shaft and a belt wheel fixedly arranged on the rotating shaft. A locking nut is arranged on the rotating shaft on one side of the belt wheel, a tension sleeve for achieving non-clearance transmission of the belt wheel and the rotating shaft is arranged on the combining portion of the belt wheel and the rotating shaft, and tension sleeves are sleeved on two sides of the combining portion of the belt wheel and the rotating shaft. When the simple clutch device is used for transmitting power, the locking nut can be screwed, the tension sleeve is axially stressed and then can generate radial pressure, outer rings of the tension sleeves and the belt wheel are tightly held together, inner rings of the tension sleeves and the rotating shaft are tightly held together, and the belt wheel is in non-clearance transmission with the rotating shaft through connection of the tension sleeves.
Description
Technical field
The utility model relates to a kind of simple clutch device, is applicable to the transmission device of computer embroidering machine.
Background technique
The transmission device of traditional computer embroidering machine is that the belt wheel that adopts the rotating shaft drive to be located in rotating shaft is irregularly realized, belt wheel is fixed on the method in rotating shaft, thereby be generally to adopt to establish the structures such as latch or keyway fix the synchronous rotation with movable belt pulley in rotating shaft, the shortcoming of this method is easily loosening, and installs also cumbersome.
Summary of the invention
For the easy shortcoming of becoming flexible and trouble being installed that the transmission device that overcomes existing computer embroidering machine exists, the utility model provides a kind of simple clutch device simple in structure, easy for installation.
The technical solution adopted in the utility model is:
The simple clutch device, comprise rotating shaft and be installed in the belt wheel in rotating shaft, it is characterized in that: be provided with locking nut in the rotating shaft of described belt wheel one side, be provided with the expansion sleeve that can realize belt wheel and rotating shaft gapless driving in the junction of described belt wheel and rotating shaft.
Further, the both sides of described belt wheel and rotating shaft junction are arranged with respectively described expansion sleeve.
The utility model adopts expansion sleeve to substitute traditional spline keyway transmission.When transferring power, tighten locking nut, make to produce radial pressure after the expansion sleeve axially loaded, expansion sleeve outer ring and belt wheel, inner ring and rotating shaft are fully held tightly, by expansion sleeve, connect, and realize belt wheel and rotating shaft gapless driving.When belt wheel and rotating shaft need to break away from, unscrew locking nut, expansion sleeve and belt wheel, disengagement is loosened in rotating shaft, and belt wheel separates with rotating shaft.By the locking nut effect, realize that transmission is high-accuracy, break away from flexible.
The beneficial effects of the utility model are embodied in: simple in structure, easy for installation.
The accompanying drawing explanation
Fig. 1 is the utility model overall structure schematic diagram.
Embodiment
With reference to Fig. 1, the simple clutch device, comprise rotating shaft 4 and be installed in the belt wheel 2 in rotating shaft 4, in the rotating shaft 4 of described belt wheel 2 one sides, be provided with locking nut 3, in described belt wheel 2 and the junction of rotating shaft 4, be provided with the expansion sleeve 1 that can realize belt wheel 2 and rotating shaft 4 gapless drivings.
Further, described belt wheel 2 is arranged with respectively described expansion sleeve 1 with the both sides of rotating shaft 4 junctions.
The utility model adopts expansion sleeve 1 to substitute traditional spline keyway transmission.When transferring power, tighten locking nut 3, make to produce radial pressure after expansion sleeve 1 axially loaded, expansion sleeve 1 outer ring and belt wheel 2, inner ring and rotating shaft 4 are fully held tightly, by expansion sleeve 1, connect, and realize belt wheel 2 and rotating shaft 4 gapless drivings.When belt wheel 2 needs to break away from rotating shaft 4, unscrew locking nut 3, expansion sleeve 1 and belt wheel 2, disengagement is loosened in rotating shaft 4, and belt wheel 2 separates with rotating shaft 4.By locking nut 3 effects, realize that transmission is high-accuracy, break away from flexible.
The described content of this specification embodiment is only enumerating the way of realization of inventive concept; protection domain of the present utility model should not be regarded as only limiting to the concrete form that embodiment states, protection domain of the present utility model also reaches the equivalent technologies means that design can be expected according to the utility model in those skilled in the art.
