This invention relates to such wheel and axle structures as are embodied in mine cars and similar cars.
The object of the invention is to produce a structure wherein the .parts are so arranged that the mine mechanic will not need to use judgment in order to get the finest adjustment of parts, namely, the play between the balls and the races this being then the play of the wheel endwise on the axle. In other words, the object is to so organize the structure that the mine mechanic need only draw the binding bolts as tight as he can draw themwhereupon the interior adjustments of play'are accurately arranged.
In the accompanying drawings,
Fig. 1 is a longitudinaLupright section along the axial line of the structure approximately on the line I-l of Fig. 2;
Fig. 2 is an upright transverse section on the line, 2-2, of Fig. 1, looking toward the left;
Fig. 3 is an upright transverse section on the line, 3--3, of Fig. 1, looking toward the right;
Fig. 4 is an upright transverse section on the line, 44, of Fig. 1, looking toward the right;
Fig. 5 is an upright transverse section on the line, 5-5, of Fig. 1, looking toward the right;
Fig. 6 is an upright transverse section on the line, 66, of Fig. 1 looking toward the right;
Fig. 7 is an upright transverse section on the line, 1-1, of Fig. 1, looking toward the right;
Fig. 8 is a horizontal section on the line, 8-8, of Fig. 1, looking downward.
Referring to said drawings, A is the body of the axle. Al is the journal. A2 is an annular collar integral with the axle between the body, A, and the journal. The outer, or right-hand end of the journal is threaded to receive a ring-form nut, A3. The wheelB, having a'hub, BI, and an end wall, B2, surroundsthe' journal. In the form shown infthe drawings, the wheel, has six spokes, B3. 'I'he alternate spokes have horizontal openings,,B4, extendingthrough the spokes approximately parallel to the journal, Al.
At the inner end ofthe hub (the end toward F the body, A,of the axle) a ring-form end plate,
B6,surrounds the collar, A2,.rotatably. On the collar, A2, are grooves, A4, adapted to receive packing to prevent'passage of lubrication from .the interior of the hub and to prevent the passage of dirt from the exterior of the hub. Through, each spoke opening, B4, thereis inserted a binding bolt, B1,- the head of the bolt being at the outer or right hand'face of the spoke and the opposite end. of the bolt being threaded into the ring-form end plate, B5. A locking plate, B8,
surrounds the bolt between the adjacent face of the spoke and the head of the bolt and bears downward on the adjacent face of the hub to prevent turning of said plate on the bolt. When the bolt has been sufiiciently turned to adjust the ring-form plate, B5, a suitable part of the plate,
B8, is to be bent over one of the faces of the bolt head. The drawings show the outer part (the part the farther from the hub) so bent.
In the form of the structure illustrated by these drawings, the function of these binding bolts is to draw the ring form end plate B6, toward, but not against, the inner or adjacent end of the hub. The function of said bolts is to draw the end plate against an adjacent ball race, as will be described further on.
Parallel to and spaced from the nut, A3, a circumferential channel, A5, is formed in the journal Al, to receive the two halves of a split ring, A6.
A hub bushing, C, surrounds and is spaced from said split ring and extends toward the end plate, B6. Opposite each half of the split ring, A6, a part of the bushing is bent downward to form a tongue, CI, directed toward the split ring to hold the two parts of the ring in the channel, A5, of the'journal.
Between the nut, A3, and the split ring, A6, a ball race, C2, surrounds the journal and bears against said nut and said split ring. For adjustment, the nut is driven against. the ball race, whereby the ball race is pressed against the split ring and the latter is pressed against the inner wall of the channel, A5. Thus the split ring forms an abutment for that ball race. On the nut, A3, are circumferential notches, A'I, any one of which may receive one end of'a locking member, A8, the other end of said-member being held between the journal and the ball race, 02. When the nut, A3, is to be turned, the outer end of the locking member, A8, is to be bent upward out of the adjacent notch, Al.
Concentric to the ball race, C2, is a companion ball race, C3. Between those ball races are balls, C4. The ball race, C3, rests against a shoulder, A9, formed on the interior of the hub. The outer end of the hub bushing, C, normally bears against the ball race, C3, and presses said race against the hub shoulder, A9.
Near the axle collar, A2, the ball race, C5, surrounds the journal, Al. Concentric to and surrounding that race is a ball race, C6. Between those two races are balls, C1. The race, C5, bears against the adjacent end of the hub bushing, C, and the adjacent face of the ring-form end race, the end plate making contact with that race and not with the adjacent end of the hub, space being left between said end plate and the end of the hub, as shown by the drawings. The binding bolts, B1, are to be set to forcibly maintain engagement of the end plate with the ball race, C6, whereby maintained binding engagement is made between the end plate and said ball race and the bushing and the ball race, C3, and the hub shoulder, A9. Thus the ball race, C6, and the ball race, C3, are locked. I have already noted that the ball race, C2, is held immovably between the nut, A3, and the split ring, A5. The ball race, C5, is not held against movement parallel to the length of the journal. That ball race is floating.
While the ring-form end plate, B6, performs a part in binding the ball races, C6 and C3, that end plate also serves as a closure for the end of the hub.
In addition to the function performed relative to the ball race, 02, the nut, A3, forms an abutment for holding the hub against outward movement on the axle; and in addition to its function relative to the ball race, C2, the split ring, A6, forms an abutment for holding the hub against inward movement on the axle, whereby the hub end wall is held away from the end of the axle, the ball races, C2 and C3, and the balls, C4, making needed engagement with the hub and the nut and the split ring. This additional functioning is to be noted in connection with the claims.
In the form shown in the drawings, the lubricant is to be introduced through the port, B9, formed in the end wall, B2, of the hub, B, and normally closed by a screw plug, BIB, of any desired form.
From the foregoing it will be seen that this invention provides for a wheel hub of maximum simplicity, cast as a unit and requiring a minimum amount of machine work without need of precise accuracy of machine work. It will also b ob.- served that provision is made for retaining grease in the lower part of the hub to a height halfway between the journal, Al, and the bottom of the hub, the leakage, in the limited desired qua tity being between the lower part of the an, nular collar, A2, and the adjacent. part of the ring-form plate, B5.
While this invention has been mentioned as applicable to wheel and axle structures such as are embodied in mine cars and similar cars, it is to be understood that the invention may be embodied in wheel and axle structures to be used otherwise than in such cars.
