Abstract
The utility model relates to a low inertia freewheel clutch, which is characterized in that a spacing disk 9 is riveted with the inner side of a gear 7, pin shafts 8 are uniformly distributed on the circumference of the gear 7, and one end of each pin shaft penetrates through the spacing disk and is coupled with the gear and the other end is sheathed with a slide block 5; a front following disk 2 is free sheathed on a shaft sleeve 4, a back following disk 3 is free sheathed on the spacing disk, and a wedge block 6 is coupled between a front spacing disk and the back spacing disk through a pin shaft 11; a suspension arm of the wedge block is contacted with the slide block 5, the driving arc-shaped surface of the wedge block is contacted with a basin-shaped ring with thin wall 1, and the wedge block is contacted with a gear pin 13 fixed on the back following disk through a return spring 10. Combined elements of the clutch belong to the contact with lower pair; the contact stress thereof is small; the requirement of assembly precision is low; when in use, the variation of frictional facter is difficult to influence the reliability; the added moment of inertia of driven elements is small.
Description
The utility model relates to a kind of free wheel device, especially lower pair inertia-type free wheel device.
At present, common on the market free wheel device roughly has two classes: roller type and wedge block type.Roller-type overrunning clutch is constructed a wedge shape space by star-wheel and ring, and roller relies on rubbing action to realize its unidirectional transmission betwixt.Wedge type over running clutch then is to substitute roller as binding member with voussoir, relies on voussoir self shape to form the angle of wedge, utilizes rubbing action to realize unidirectional transmission again.Roller type and wedge block type belong to friction overdrive clutch together, and binding member all belongs to higher pair contact, and its contact stress is bigger, and assembly precision is had relatively high expectations, in the use variation of friction factor relatively more responsive to the influence of reliability, and the added moment of inertia of driven member is bigger.
The purpose of this utility model provides a kind of lower pair inertia-type free wheel device, be low auxiliary structure by changing high auxiliary structure, the modified line contact is the face contact, solves the variation problem big to the added moment of inertia that influences tender subject and driven member of reliability of friction factor in using.
Concrete scheme of the present utility model is: comprise thin-walled bowl-shaped ring, axle sleeve, gear, it is characterized in that: A. has position-arresting disk in the riveted joint of the inboard of gear, evenly be furnished with bearing pin along circumference of gear, one of bearing pin passes position-arresting disk and connects with gear, other end suit slide block; B. preceding servo-actuated is circled or whirl in the air and is enclosed within on the axle sleeve, and back follower disk is enclosed within on the position-arresting disk surely, and voussoir is connected between the forward and backward position-arresting disk through bearing pin; C. the cantilever of voussoir contacts with slide block, and the driving cambered surface of voussoir contacts with the thin-walled bowl-shaped ring, and voussoir is the shelves pin contacts on the follower disk through return spring and after being fixed on.
Adopt such scheme, the force part of binding member is surface contact state, and contact stress is less, and the variation of the factor that rubs in the use is insensitive to the influence of reliability, and the improvement of binding member stress is minimized material and heat treatment requirements, has reduced cost; Because clutch whether " stuck " is only relevant with the entering angle of slide block, whether " skid " and depend on the stress of voussoir, thereby can give and distribute satisfiedly by rational design, improved the reliability of using; Again owing to be fixed on thin-walled bowl-shaped ring very light weight on the driven member, thereby added moment of inertia is very little.
Below in conjunction with drawings and Examples the utility model is further specified:
Fig. 1 is a plan view of the present utility model;
Fig. 2 is the P-P sectional view of Fig. 1.
Please see Figure 1, Fig. 2, the utility model is made up of thin-walled bowl-shaped ring 1, preceding follower disk 2, back follower disk 3, axle sleeve 4, slide block 5, voussoir 6, gear 7, bearing pin 8, position-arresting disk 9, return spring 10, bearing pin 11, rivet 12, shelves pin 13, structure characteristic of the present utility model is: A. has position-arresting disk 9 in the riveted joint of the inboard of gear 7, evenly be furnished with bearing pin 8 along gear 7 circumference, 8 one of bearing pins pass position-arresting disk 9 and connect with gear 7, other end suit slide block 5; B. preceding follower disk 2 skies are enclosed within on the axle sleeve 4, and back follower disk 3 skies are enclosed within on the position-arresting disk 9, and voussoir 6 is connected between the forward and backward position-arresting disk 2,9 through bearing pin 11; C. the cantilever of voussoir 6 contacts with slide block 5, and the driving cambered surface of voussoir 6 contacts with thin-walled bowl-shaped ring 1, voussoir 6 through return spring 10 be fixed on after shelves pin 13 on the follower disk 3 contact.
As shown in Figure 2: the driving cambered surface of voussoir 6 and the inwall cambered surface of thin-walled bowl-shaped ring 1 are amplexiformed, and both radiuses equate.
The utility model is performed such work: before work, earlier thin-walled bowl-shaped ring 1 is fixed on the driven member, 4 skies of axle sleeve that are fitted in gear 7 are enclosed within on the driven member axle, enter work then.When gear 7 was rotated counterclockwise as shown in Figure 2, because the existence of moment of inertia, preceding follower disk 2 and back follower disk 3 be rotation thereupon immediately not, and the voussoir 6 on it can only be rotated around bearing pin 11 by the effect of slide block 5, will go up cambered surface and press to thin-walled bowl-shaped ring 1.When frictional force surpassed the driven member resisting moment, voussoir 6, the thin-walled bowl-shaped ring 1 of front and back follower disk 2,3 on being fixed on driven member rotated synchronously with gear 7, thereby realize unidirectional transmission.When the driven member rotating speed is higher than driving link; thin-walled bowl-shaped ring 1 imposes on the frictional force of voussoir 6 away from slide block 5; meanwhile, return spring 10 makes voussoir 6 counterrotatings break away from thin-walled bowl-shaped ring 1 under shelves pin 13 effects that are fixed on the follower disk 3 of back, thereby realizes contactless surmounting.Wherein, the permission wear extent of non-contacting gap and friction pair is controlled by position-arresting disk 9.
