Description
76155-S~
1087~9 The present invention relates to overrunning clutches and more particularly to a cage therefor. In overrunning clutches, it is customary to provide concentric inner and outer races having an annular space between the races in which a plurality of one way wedging members are located. A cage is frequently employed for maintaining the wedging members in a desired circumferential spacing and for mounting appropriate energizing spring means arranged for biasing the wedging members for wedging engagement with the races. Frequently, the cage, wedging members and energizing spring means are preassembled and handled as a removable subassembly which is installed endwise into the annular space between a pair of concentric races. Some form of retaining means is desirable for preventing unintended axial displacement of the cage and wedging member subassembly with respect to the races.
In the prior art it is known to provide a subassembly of wedging members and energizing means in a substantially rigid cage which is inserted endwise into a recess defined by a race and an end wall and to secure the subassembly against axial displacement by means of a bolted on cover plate closing the open end of the recess. It is also known to provide a pair of axially spaced retainer ring grooves in one of the races. In the latter construction a rear retainer ring is installed in the rear groove, the subassembly is installed endwise abutting the rear retainer ring and finally a front retainer ring is installed in the front groove such that the subassembly is retained against axial displacement by the front and rear retainer rings. The latter construction -1- ~i 1~871~9 requires the handling and installation of two retainer rings in addition to the subassembly, and in some instances the installation and removal of the rear retainer ring may become a difficult and time-consuming exercise.
The present invention resides, therefore, in an overrunning clutch including inner and outer concentric races having wedging members disposed therebetween, one of the races including a circumferentially extending retainer groove. In the present invention, there is provided a bodily warpable cage including a substantially annular side plate having a plurality of spacer bars extending axially therefrom and defining circumferentially spaced pockets arranged and disposed for receiving the wedging members.
At least one of the spacer bars include a radially extending retainer tab disposed substantially parallel to and spaced axially from the side plate. The side plate is resiliently warpable in an axial direction in response to radial de-flection of the retainer tab permitting releasable engage-ment of the retainer tab with the retainer groove.
The resiliently warpable cage member is capable of being flexed during installation with a clutch race so as to engage a retaining groove in the race and thereby prevent unintended axial displacement of a cage subassembly with respect to the race. The various advantages of the invention will become more readily discernable from the following description of a preferred embodiment of the invention with the aid of the accompanying drawings, in which:
FIGURE 1 is an axial end elevation view of an overrunning clutch including a bodily warpable cage according to the present invention;
FIGURE 2 is a fragmentary view to enlarged scale of a portion of the clutch shown in FIGURE 1;
1087~9 The present invention relates to overrunning clutches and more particularly to a cage therefor. In overrunning clutches, it is customary to provide concentric inner and outer races having an annular space between the races in which a plurality of one way wedging members are located. A cage is frequently employed for maintaining the wedging members in a desired circumferential spacing and for mounting appropriate energizing spring means arranged for biasing the wedging members for wedging engagement with the races. Frequently, the cage, wedging members and energizing spring means are preassembled and handled as a removable subassembly which is installed endwise into the annular space between a pair of concentric races. Some form of retaining means is desirable for preventing unintended axial displacement of the cage and wedging member subassembly with respect to the races.
In the prior art it is known to provide a subassembly of wedging members and energizing means in a substantially rigid cage which is inserted endwise into a recess defined by a race and an end wall and to secure the subassembly against axial displacement by means of a bolted on cover plate closing the open end of the recess. It is also known to provide a pair of axially spaced retainer ring grooves in one of the races. In the latter construction a rear retainer ring is installed in the rear groove, the subassembly is installed endwise abutting the rear retainer ring and finally a front retainer ring is installed in the front groove such that the subassembly is retained against axial displacement by the front and rear retainer rings. The latter construction -1- ~i 1~871~9 requires the handling and installation of two retainer rings in addition to the subassembly, and in some instances the installation and removal of the rear retainer ring may become a difficult and time-consuming exercise.
The present invention resides, therefore, in an overrunning clutch including inner and outer concentric races having wedging members disposed therebetween, one of the races including a circumferentially extending retainer groove. In the present invention, there is provided a bodily warpable cage including a substantially annular side plate having a plurality of spacer bars extending axially therefrom and defining circumferentially spaced pockets arranged and disposed for receiving the wedging members.
At least one of the spacer bars include a radially extending retainer tab disposed substantially parallel to and spaced axially from the side plate. The side plate is resiliently warpable in an axial direction in response to radial de-flection of the retainer tab permitting releasable engage-ment of the retainer tab with the retainer groove.
The resiliently warpable cage member is capable of being flexed during installation with a clutch race so as to engage a retaining groove in the race and thereby prevent unintended axial displacement of a cage subassembly with respect to the race. The various advantages of the invention will become more readily discernable from the following description of a preferred embodiment of the invention with the aid of the accompanying drawings, in which:

Referring to the drawings an overrunning clutch 20 includes an outer race member 21, an inner race member 22, and a cage subassembly 23. The cage assembly 23 includes a plurality of wedging members 24 and energizing springs 26, as well as a cage member 27. In the illustrated form of the invention, the outer race member 21 includes a race formed by a circumferential series of arcuate surfaces 28 and camming surfaces 29 connected by a surface 30 which together define a circumferential series of recesses 31. The wedging members 24 are in the form of cylindrical wedging rollers which are engageable with the camming surfaces 29 and with a smooth cylindrical surface 32 on inner race member 22. In alternate forms of clutches, the camming surfaces occur in the inner race member and the smooth race occurs in the outer race member. A circumferentially extending retainer groove 33 is formed in one of the race members and is herein shown as being formed in outer race member 21 disposed radially outwardly and axially forward of the camming surfaces 29, 29 etc. If desired, the retainer groove may be formed in the race member having the smooth race.
The bodily warpable resilient cage member 27 includes an annular side plate 36 having an outer spacer bar 37 and an inner spacer bar 38 extending axially therefrom at -` 1087119 ea~.n of a plurality of circumferentially spaced locations around the side plate 36. Side plate 36 includes a plurality of radially projecting ears 41 engaging the recesses 31 formed by the junction surface 30 between adjacent arcuate surfaces 28 and camming surfaces 29. Each lower spacer bar 38 has a radial wall 42 and a circumferential finger 39 extending therefrom parallel to and axially spaced from side plate 36. Radial wall 42 serves as mounting means for securing one end of a pleated energizing spring 26. When the cage subassembly 23 is handled as a unit, a pleated spring 26 urges the next adjacent roller 24 into contact -with the next pair of spacer bars 37, 38 thus retaining the roller in the pocket defined by side plate 36 at the rear, the finger 39 in front, the radial wall 42 on the left and the spacer bars 37, 38 on the right. When the cage subassembly 23 is installed with a race member having camming surfaces, the energizing springs 26 urge the wedging members 24 into engagement with the camming surfaces 29. When both races are assembled, the wedging members engage the smooth race 32 and camming surfaces 29, and disengage spacer bars 37, 38.
In the embodiment illustrated in FIGURES 1 - 7, certain of the outer spacer bars 37 includes radial retainer tabs 43 extending parallel to and axially spaced from side plate 36. In FIGURE 1 four retainer tabs 43 are shown equally spaced about the cage 27. In FIGURES 1 and 2 the retainer tabs 43 are shown as being received within the retainer groove 33. FIGURE 3 - 6 illustrate resilient deflection of a retainer tab permitting engagement of a retainer tab with a retainer groove, the deflection of the tab being due, in part, to warping of side plate 36.

-`" 1087119 In FIGURE 3, the cage subassembly 23 is shown axially in front of outer race member 21 preparatory to installation of the subassembly with the race member. In FIGURE 4, the cage subassembly is moved endwise part way into outer race member 21 with ears 41 engaging recesses 31.
In FIGURE 5, the radial retainer tab has been deflected toward the axis which causes momentary flexing or warping of annular side plate 36. FIGURE 6 shows the cage subassembly 23 installed in outer race member 21 wherein cage member 27 has recovered from the warping of FIGURE 5 to resume its normal shape with retainer tab 43 engaging retainer groove 33. FIGURE 7 shows the inner race member 22 inserted into cage subassembly 23 after the cage subassembly has resumed its normal configuration and further illustrates the advantage that the retainer tab or tabs engagement with groove 33 prohibits axial displacement of the cage subassembly in either axial direction. Inasmuch as retainer tabs 43 secure the cage against axial displacement in both directions, the need for additional retainer means adjacent sideplate 36 is avoided.
Removal of the cage subassembly is accomplished by a reversal of the steps illustrated in FIGURES 1 through 7, that is, the inner race member is removed, the cage is warped to release retainer tab 43 from retainer groove 33, and the subassembly ~3 is slid axially out of the outer race member 21.
A modified form of construction is shown in FIGURE
8 wherein a ret~iner tab 44 îs formed on finger 39 and therefore receives its support from spacer bar 38 and radial wall 42 rather than from spacer bar 37.

FIGURE 11 shows a modification of the retainer tab 43 shown in FIGURE 1 - 7 in which a tool receiving notch 51 is formed on the tab providing a recess for insertion of a tool whereby the tab can be sprung radially inwardly for release from retainer groove 33. FIGURE 12 shows a tab construction similar to FIGURE 11, in which the tool receiving recess is provided by the tool aperture 52 rather than by the notch ~1.
FIGURE 13 shows a further modification of cage member 27 in which annular side plate 36 is separated to provide two adjacent end portions 53 and 54 defining a split ring construction. The split ring construction facilitates warping of the side plate 36 and is particularly beneficial in small diameter clu~ches.

Referring to the drawings an overrunning clutch 20 includes an outer race member 21, an inner race member 22, and a cage subassembly 23. The cage assembly 23 includes a plurality of wedging members 24 and energizing springs 26, as well as a cage member 27. In the illustrated form of the invention, the outer race member 21 includes a race formed by a circumferential series of arcuate surfaces 28 and camming surfaces 29 connected by a surface 30 which together define a circumferential series of recesses 31. The wedging members 24 are in the form of cylindrical wedging rollers which are engageable with the camming surfaces 29 and with a smooth cylindrical surface 32 on inner race member 22. In alternate forms of clutches, the camming surfaces occur in the inner race member and the smooth race occurs in the outer race member. A circumferentially extending retainer groove 33 is formed in one of the race members and is herein shown as being formed in outer race member 21 disposed radially outwardly and axially forward of the camming surfaces 29, 29 etc. If desired, the retainer groove may be formed in the race member having the smooth race.
The bodily warpable resilient cage member 27 includes an annular side plate 36 having an outer spacer bar 37 and an inner spacer bar 38 extending axially therefrom at -` 1087119 ea~.n of a plurality of circumferentially spaced locations around the side plate 36. Side plate 36 includes a plurality of radially projecting ears 41 engaging the recesses 31 formed by the junction surface 30 between adjacent arcuate surfaces 28 and camming surfaces 29. Each lower spacer bar 38 has a radial wall 42 and a circumferential finger 39 extending therefrom parallel to and axially spaced from side plate 36. Radial wall 42 serves as mounting means for securing one end of a pleated energizing spring 26. When the cage subassembly 23 is handled as a unit, a pleated spring 26 urges the next adjacent roller 24 into contact -with the next pair of spacer bars 37, 38 thus retaining the roller in the pocket defined by side plate 36 at the rear, the finger 39 in front, the radial wall 42 on the left and the spacer bars 37, 38 on the right. When the cage subassembly 23 is installed with a race member having camming surfaces, the energizing springs 26 urge the wedging members 24 into engagement with the camming surfaces 29. When both races are assembled, the wedging members engage the smooth race 32 and camming surfaces 29, and disengage spacer bars 37, 38.
In the embodiment illustrated in FIGURES 1 - 7, certain of the outer spacer bars 37 includes radial retainer tabs 43 extending parallel to and axially spaced from side plate 36. In FIGURE 1 four retainer tabs 43 are shown equally spaced about the cage 27. In FIGURES 1 and 2 the retainer tabs 43 are shown as being received within the retainer groove 33. FIGURE 3 - 6 illustrate resilient deflection of a retainer tab permitting engagement of a retainer tab with a retainer groove, the deflection of the tab being due, in part, to warping of side plate 36.
