Abstract
A torque limiter is provided with a driven shaft, a driven wheel is sleeved on one end of the driven shaft, and is fixed on the driven shaft, the driven wheel and a driving wheel are coaxially fitted and respectively provide with a semicircular notch, the semicircular notches on the driven wheel and the driving wheel are oppositely fitted to form a cylindrical pin hole, and a torque spring is arranged between the driving wheel sleeved on the driven shaft and a fixing ring. The structure of the torque limiter is simple, and the torque limiter is a clutching protector for mechanical drive, which is used in the machining of mechanical parts.
Description
Technical field
The utility model relates to mechanical transmission fields, refers in particular to a kind of structure of machinery or device of manufacturing spectacle component.
Background technique
Disclosed a kind of drive mechanism is made up of driving wheel and driven shaft cooperation on the market, described glasses component such as spring case, catapult shell etc. are arranged on the driven shaft, during driving wheel work, the drive driven shaft rotates, thereby can realize the sharp processing of spring case or catapult shell; And when spring case or catapult shell run into the variation shape, as cut when incomplete, because of driving wheel can not produce displacement relatively with driven shaft, driving wheel rotates synchronously with driven shaft by force and loses the parts that are connected driving shaft and driven shaft like this, causes the transmission device spoilage to strengthen; For example: the mode that machinery is installed socket light bulb is this situation, and after putting in place on the bulb, driving shaft needs to separate with driven shaft, reworks after resetting after rotating a circle again; Therefore be necessary between driving wheel and driven shaft, to be provided with a torsion limting mechanism, to guarantee the proper functioning of described drive mechanism.
The model utility content
The purpose of this utility model provides the torque force limiting device that clutch between a kind of driving wheel and the driven shaft cooperates usefulness; The torsion that is subjected to when driven shaft is during less than the clutching force of driving wheel and driven shaft, and driving wheel drives driven shaft and rotates synchronously; The torsion that is subjected to when driven shaft is during greater than the clutching force of driving wheel and driven shaft, and driving wheel separates with driven shaft, and driving wheel still rotates, and driven shaft is motionless, by manual operation, take off parts to be processed on the driven shaft after, driving wheel cooperates rotation again with driven shaft.
The technical solution of the utility model is achieved in that
A kind of torque force limiting device is provided, it is characterized in that: a driven shaft is arranged, driven shaft one end socket one follower, described follower is fixed on the driven shaft, follower and driving wheel coaxial cooperation and be provided with semi-circular recesses, the semi-circular recesses on follower and the driving wheel is provided with in opposite directions; Semi-circular recesses on follower and the driving wheel cooperates formation one cylinder pin hole; Be socketed between driving wheel on the driven shaft and the retaining ring and be provided with a torque spring.The size of described torque force limiting device torsion is by the elasticity coefficient decision of torque spring.
Aforesaid torque force limiting device is characterized in that: described follower is provided with counterbore, is provided with nut in the counterbore.Insert back rotation in the counterbore by nut, and follower be fixed on the driven shaft,
Aforesaid torque force limiting device is characterized in that: described follower and driven shaft are connected as a single entity.
When the utility model uses, select earlier elasticity coefficient appropriate torsion spring as required, after the technique scheme connection, during processing accessories, driving wheel rotation, the torsion of setting because of torque spring be less than setting value, and driving wheel docks by straight pin with half groove on the follower and do not produce slide relative, like this, driving wheel drive follower rotates synchronously; When part processing is interrupted or finish, follower be hampered and the torsion that produces greater than setting value, the straight pin that driving wheel is crossed in follower half groove produces slide relative, thereby has protected follower and part not to be subjected to be damaged because of incarceration.
The utility model is simple in structure, the clutch protective device when providing a kind of mechanical transmission for the processing of component of machine.
Description of drawings
Fig. 1 is a kind of embodiment's of the utility model a structural drawing.
Fig. 2 is the composite structure schematic representation of Fig. 1.
Embodiment
Below in conjunction with accompanying drawing 1 to accompanying drawing 2 embodiment of the present utility model is described:
A kind of torque force limiting device is provided, one driven shaft 1 is arranged, driven shaft 1 one end sockets one follower 2, described follower 2 is fixed on the driven shaft 1, follower 2 and driving wheel 3 coaxial cooperation and be provided with semi-circular recesses 21,31, the semi-circular recesses 21 of follower 2 and the semi-circular recesses 31 of driving wheel 3 cooperate the hole that constitutes ccontaining straight pin 22 in opposite directions; Be socketed on the driven shaft 1 driving wheel 3 and and the fixing retaining ring 5 of driven shaft screw thread between be provided with a torque spring 4.The size of described torque force limiting device torsion is by the elasticity coefficient decision of torque spring 4.
Described follower 2 is provided with counterbore 23, is provided with nut 24 in the counterbore 23.Insert back rotation in the counterbore 23 by nut 24, and follower 2 is fixed on the driven shaft 1.
On the basis of the foregoing description, described follower 2 is connected as a single entity with driven shaft 1, is the disjunctor parts of integral type.
Obviously, in mechanical transmission, carry out initiatively exchanging, also fall into this patent embodiment's scope with the equivalence of driven setting.
Though above shown detailed embodiment of the present utility model, those skilled in the art is under prerequisite of the present invention, can carry out the part modifications and changes; The content of mentioning in description above and the accompanying drawing is the illustration of property as an illustration only, is not to restriction of the present utility model, has the torque force limiting device of above-mentioned technical characteristics, all falls into this patent protection domain.
Claims (3)
1. torque force limiting device, it is characterized in that: a driven shaft is arranged, rotatingshaft one end socket one follower, described follower is fixed on the driven shaft, follower and driving wheel coaxial cooperation and be provided with semi-circular recesses, the semi-circular recesses on follower and the driving wheel cooperate in opposite directions and constitute a cylinder pin hole; Be socketed between driving wheel on the driven shaft and the retaining ring and be provided with a torque spring.
