Abstract
The utility model relates to a friction type one way clutch which is characterized in that a movable clutch connector (2) is connected with a driving shaft (3) through screw threads with relatively great lead angles or multi-head screw threads, the connecting end of the movable clutch connector (2) is provided with a friction connecting surface, and a friction connecting surface which can be engaged with the friction connecting surface of the movable clutch connector (2) is arranged on a driven shaft (1). The utility model is used for connection of driving shafts with relatively high rotation speed and driven shafts, and the connection needs one way clutch. The friction type one way clutch has the advantages of automatic engaging and disengaging ability, no noise, easy fabrication, etc.
Description
The utility model belongs to the mechanical clutch field, specifically a kind of can folk prescription under running, automatically connect and separation machinery equipment in driving shaft and the coupling of driven shaft.
According to the investigation of existing market with relevant technical data is retrieved, in existing various mechanical clutches, all do not have with the similar technology of the utility model technology.The clutch of existing one-way clutch mainly contains roller overrunning clutch, voussoir free wheel device, ratchet type overrunning clutch, sliding lock formula free wheel device etc., these clutches mainly exist following point: (1) complex structure, boundary dimension are big, manufacturing and installation difficulty, are not suitable for the needs of product structure miniaturization development; When (2) rotating, wearing and tearing and noise are arranged between each coupling in the clutch under the situation of clutch separation, particularly running up down, wearing and tearing and noise are just more obvious.
Goal of the invention of the present utility model is exactly the disadvantage that overcomes above-mentioned prior art, the time does not have wearing and tearing and muting overrunning clutch for the master and slave moving axis that needs one-way clutch provides a kind of simple in structure, cheap for manufacturing cost, running.
The utility model is compared with existing various overrunning clutchs, when having simple in structure, transmission noiseless, manufacturing and installation easily, do not have advantages such as wearing and tearing, clutch boundary dimension are less between the coupling, the manufacture cost of whole clutch has only 1/2nd to 1/4th of roller-type overrunning clutch, and be more than five times of roller overrunning clutch working life.
Technical characteristics of the present utility model is: be provided with an activity clutch coupling ［ 2 ］ on driving shaft ［ 3 ］, be to adopt they to be linked together between activity clutch coupling ［ 2 ］ and the driving shaft ［ 3 ］ than the screw thread of great-lift angle or the screw thread of bull, joining end on activity clutch coupling ［ 2 ］ is provided with a friction conjunction plane, is being provided with the friction conjunction plane that an energy and friction conjunction plane on the activity clutch coupling ［ 2 ］ mesh together on the driven shaft ［ 1 ］.
Description of drawings:
Fig. 1 shows a kind of friction type overrunning clutch of structure, also is a kind of embodiment's of the present utility model schematic representation.
Fig. 2 is the partial enlarged view of Fig. 1.
Fig. 3 shows the friction type overrunning clutch of another kind of structure, also is another kind of embodiment's of the present utility model schematic representation.
Mark among the figure:
Driven shaft ［ 1 ］, activity clutch coupling ［ 2 ］, driving shaft ［ 3 ］, fixing clutch coupling ［ 4 ］.
Fig. 1 and Fig. 2 show the embodiment of a kind of structure of the present utility model, activity clutch coupling ［ 2 ］ is contained on the driving shaft ［ 3 ］, be to adopt they to be linked together between activity clutch coupling ［ 2 ］ and the driving shaft ［ 3 ］ than the screw thread of great-lift angle or the screw thread of bull, joining end on activity clutch coupling ［ 2 ］ is shaped on a friction conjunction plane, is shaped on the friction conjunction plane that an energy and friction conjunction plane on the activity clutch coupling ［ 2 ］ mesh together at the joining end on the driven shaft ［ 1 ］.When the Hand of spiral of the connection screw thread on driving shaft ［ 3 ］ and the activity clutch coupling ［ 2 ］ is dextrorotation, driving shaft ［ 3 ］ is when contrary clockwise direction starting and running, because activity clutch coupling ［ 2 ］ is subjected to action of inertia, activity clutch coupling ［ 2 ］ and driving shaft ［ 3 ］ are produced relative rotation, consequently activity clutch coupling ［ 2 ］ is to the direction motion of driven shaft ［ 1 ］ on axial direction, and at this moment this clutch has just meshed together automatically; When starting of driving shaft ［ 3 ］ clockwise direction and running, because activity clutch coupling ［ 2 ］ is subjected to action of inertia, activity clutch coupling ［ 2 ］ and driving shaft ［ 3 ］ are produced relative rotation, consequently activity clutch coupling ［ 2 ］ is to the direction motion away from driven shaft ［ 1 ］ on axial direction, and at this moment this clutch can be separated automatically; When driving shaft ［ 3 ］ and driven shaft ［ 1 ］ when meshing together, driving shaft ［ 3 ］ is when clockwise direction turns round, because activity clutch coupling ［ 2 ］ is subjected to the effect of the warping force on the driven shaft ［ 1 ］, activity clutch coupling ［ 2 ］ and driving shaft ［ 3 ］ are produced relative rotation, consequently activity clutch coupling ［ 2 ］ is to the direction motion away from driven shaft ［ 1 ］ on axial direction, and at this moment this clutch can be separated automatically.
Fig. 3 shows the embodiment of another kind of structure of the present utility model, fixedly clutch coupling ［ 4 ］ is fixed on the driven shaft ［ 1 ］, activity clutch coupling ［ 2 ］ is contained on the driving shaft ［ 3 ］, be to adopt they to be linked together between activity clutch coupling ［ 2 ］ and the driving shaft ［ 3 ］ than the screw thread of great-lift angle or the screw thread of bull, joining end on activity clutch coupling ［ 2 ］ is shaped on a friction conjunction plane, is shaped on the friction conjunction plane that an energy and friction conjunction plane on the activity clutch coupling ［ 2 ］ mesh together on fixing clutch coupling ［ 4 ］.When this clutch can mesh together, and when can separate, and reason is said identical with above-mentioned embodiment, has here just no longer narrated.
From two above-mentioned embodiments as can be seen, the friction type overrunning clutch of the utility model technology is in engagement (promptly connect) on what sense of rotation or to separate be that Hand of spiral by the connection screw thread on driving shaft ［ 3 ］ and the activity clutch coupling ［ 2 ］ decides.Besides because the connection of activity clutch coupling ［ 2 ］ and driving shaft ［ 3 ］ is to adopt scyewed joint, so the moment of torsion of this clutch transmits is big more, friction conjunction plane on the activity clutch coupling ［ 2 ］ is just pressed to the friction conjunction plane that is arranged on the driven shaft ［ 1 ］ more, so in the engagement driving process, generally skidding can not occur.
For the friction type overrunning clutch that makes the utility model technology can mesh (promptly connecting) better automatically and separate, the rotary centerline that departs from master and slave moving axis can be made by the center of mass of activity clutch coupling ［ 2 ］, depart from the big I of the rotary centerline of master and slave moving axis and decided by the rotating speed of driving shaft ［ 3 ］, the high more bias of rotating speed is more little.
