EQUALIZl NG-G EAR.
SPECIFICATION folming part of Letters Patent No. 571,187, dated November 10, 1896.
Application filed March 1 1, l 8 9 5.
thereof, reference being had to the accompanying drawings, and to the letters of referro ence marked thereon, which form a part of this specification.
This invention relates to improvements in equalizing-gears, and relates more particularly to an equalizing device for use in connection with a two-part shaft or axle which encounters a variable resistance at each of its ends, the equalizing device being interposed between said points of resistance and serving to equalize the resistance of the two sides. The device is adapted for use for relieving the torsional strain on a driven axle incident to the unequal rate of travel of the wheels fixed thereon in traversing curves,
and also for equalizing the power transmitted from a motor or prime mover to any drivingshaft encountering a variable resistance at its opposite ends, as hereinbefore described.
The object of the invention is to provide an improved construction in devices of the character above referred to;'and the invention consists in the matters hereinafter described and more particularlypointed out in the appended claims.
- The invention may be more readily understood by reference to the accompanying drawings, in which Figure 1 is an axial section of a shaft and equalizinggear embodying my invention. Fig. 2 is a similar view of the annular gear- 40 casing removed from the shaft. Fig. 3 is an end elevation of the same, looking at the lefthand end of Fig. 2; Fig. 4 is an end eleva tion of the gear-retaining plate in position within the annular gear-casing, taken on line 4 at of Fig.1 and looking in the direction of the arrows. Figs. 5 and 6 are inner .and outer faced views, respectively, of the gearplate removed from the gear-casing. Fig. 7'
Serial No. 541,229. (No model.)
is a transverse section of the same, taken on line'7 7 of Fig. 6. Fig. 8 is a central trans-- verse sectional view wherein the gear is shown as forming a core of an armature. Fig. 9 is an axial section of the same.
Referring to said drawings, A A designate the two adjacent ends of a shaft or axle made in two independently-revoluble alined sections. v
C, Figs. 1. and 2, designates a casting mounted concentrically with the axis of the shaft and constituting principally a gearsupport, within which are journaled one or more (in the present instance four) miter-gears D, having their axes disposed radially and at right angles to the aXis of the shaft.
In the construction herein shown the gearsupport C is revolubly mounted concentrically with the shaft by means of spindle projections b 1), extending from opposite sides thereof and engaging axial recesses in'the adjacent ends of the shaft-sections, said spindle projections being herein shown as provided in the form of a core or mandrel which extends through the gear-support, and the opposite ends of which are each tapered from the point of juncture with the gear-support to its outer end and fit accurately Within the correspondingly-shaped recesses of the shaftsections A and A. By means of the above construction the shaft-sections are held rigidly in alinement, but are permitted to rotate independently of each other. I
Referring more particularly to the construction of the gear-support C, the same comprises an inner hub portion 0, having a bore c,withinwhich is located the mandrel B, a keywayc formed longitudinally with the bore for the reception of a key 0 a flat or disk-shaped portion 0 which forms with the hub the pinion-support proper, and an outer cylindrical portion 0 constituting in effect oppositely-extending annular flanges on the periphery of the disk part c. As herein shown the 'ends of the hub and the adjacent ends of the shaft-sections have interiitting parts provided with oppositely-arranged annular rabbets c a, respectively, thereby forming an overlapping joint having square abutting shoulders. In one face of the disk are formed radially-disposed semicylindric j ournal-recesses c for the reception of the journals of the miter-pinions D, the said disk 0* being also provided with an opening 0 extending across each j ournal-recess for the reception of the body of the gear,-as shown more clearly in Fig. 3.
E is a second annular casting forming a gear-retaining plate adapted to fit within one end of the casting O. This latter casting comprises a hub e, which fits upon the exterior of the hub c, aradially-disposed web 6, adapted to fit against the face of the disk 0 provided in its proximate face with semicylindric journal-recesses e and openings e, which are similar to and register with those of the castings C, and an annular flange 6 which fits against the inner face of the part c of the casting C.
F F designate miter-gears keyed concentrically upon the ends of the shaft-sections A and A, respectively, in position to intermesh with the diametrically opposite sides of the miter-gears D I).
G G designate bearing-rings rigidly supported upon the cylindric flanges of the gearsupport 0 and arranged to overlap portions of the gears F F, thereby forming bearings which prevent said gears from endwise movement or separation from the miter-pinions D. The bearing-rings G G are herein shown as secured in position by means of through-bolts 9, passed through suitable apertures in the margins of the rings and through corresponding apertures formed in the disk portions 0 and 6. Obviously said bearing-rings G will sustain the principal part of the endwise thrust due to the tendency of the miter-gears to separate, and in order to reduce the friction between the bearing-rings and annular gears annular roller-bearing races g and f are formed in the adjacent surfaces of said parts, within whichare arranged antifrictionroller bearings II.
It will be obvious that the bearing-rings G G need not necessarily extend inward or overlap the peripheries of the gears F F more than sufficient to form suitable bearings between said parts, but in order to form a complete housing for the entire gear mechanism both the cylindric flanges c of the gear-support 0 and the said bearing-rings are made imperforate, and the latter are extended inwardly and provided with out-turned hub portions g, which embrace and form tubular bearings for the hub portions of the gears F F.
I I designate annular glands closely fitted upon the respective ends of the shaft-sections A A and each provided at its periphery with an internal]y-threaded flange 1', adapted to fit upon the correspondinglythreaded tubular bearings g. Between the inner face of each gland and the end of the gear F or F a packing-ring J is interposed, and preferably an antifriction-washer K will also be interposed between the inner face of the gland and the end of the casing G or G and packing-rin g J.
1 \Vith the various parts constructed and arranged as above described it will be obvious that each end of the shaft may rotate with relation to the other and that whenever the resistance or friction on one end of the shaft exceeds that of the other that end will be re tarded, the shafts will turn with relation to each other, and through the medium of the miter-gears the resistance will be distributed or equalized between the two ends of the shaft.
I am aware that equalizing-gears similar in principle to that herein described have before been applied both to power-shafts and to the axles of vehicles, but the general construction herein set forth is, so far as I am aware, novel and possesses important features of improvement.
The construction as a whole is extremely simple, compact, and easy of access for inspection or repairs. The use of the rollerbearings described is of special utility, since practically the entire spreading or endwise thrust on the miter-gears is received and carried directly upon said rollers, and the friction is thereby reduced to a minimum.
The tapered form of the spindle projection is also a feature of importance, especially when, as herein shown, used in conjunction with shaft-sections abutting against the relatively fixed hub of the spindle. With the parts thus constructed and arranged they are to a certain extent self-adjusting or compensating for wear, since as the ends of the shaftsections are worn away by contact with the hub of the spindle the through-bolts may be tightened to bring said sections together. This will result in closing up the joints at all places of principal wear, to wit, between the shaft-sections and spindle, between the mitergears, and between the ends of the shaft-sections and hub of the spindle.
The construction hereinbefore described and illustrated in Figs. 1 to 7, inclusive, is such a one as will be found suitable for application to any driven shaft, and the power may be transmitted to the device either by means of a driving-belt applied directly to the exterior of the casing by providing the latter with external gear-teeth with which a suitable driving-pinion meshes or otherwise.
In Figs. 8 and 9, however, I have illustrated anovel combination wherein the power for driving the axle or shaft is transmitted thereto through the equalizing-gear by means of electric motor elements mounted concentrically around the device and of which motor said gear and casing as a whole forms the movable part. It will be obvious that such a combination possesses many valuable features. The peculiarly compact arrangement of the parts of the device enables it to perform the function of an armature-core practically as well as though it were a solid mass of iron,while the arrangement is such that the stationary elements of the motor maybe built or mounted upon the device with great facility. As shown in said Figs. 8 and 9, which are to a certain extent diagrammatic, K designates the coil-sections of the rotary armature,which sections are secured directly upon the cylindric exterior of the gear-casin g. L L designate two rectangular iron frames mounted at their longitudinal centers on the shaft or axle at each side of the gear-casing, and arranged to extend radially at right angles to the shaft and to each other. These rectangular frames L L form four symmetrically-disposed field-mag net supports, each of which carries a mass of iron constituting one of the stationary elements of the motor. Obviously the field-magnet-carrying frames will be mounted upon the shaft-sections, so as to permit free rotation of the latter, being to this end provided with hubs ZZ,forming journal-boxes, and will be held from rotation with the shaft by any suitable connections between said frames and the truck-frame of the car. Preferably a suitable housing or casing :M will be arranged to inclose the entire device. A desirable form of construction for these supporting-arms will be that herein illustrated, wherein each arm comprises a pair of channel-irons placed back to back and bolted together, as indicated clearly in Fig. 8.
It will be understood, of course, that the windings and connections of the fixed and moving elements of the motor may be of any usual form, the drawings: herein being intended merely to illustrate diagrammatically the general arrangement.
