RICHARD G. BARZEN, OF KANSAS CITY, MISSOURI, ASSIGNOR TO ENGLISH BROTHERS MACHINERY COMPANY, KANSAS CITY, MISSOURI, :A CORPORATION OF MISSOURI.
LUBRICATING SYSTEM FOR HoIsT DRUMS.,
Application led January My invention relates to improvements in lubricating systems for hoistdrums, and While particularly Well adapted for use in connection with hoist c ruins, it may be advantageously adapted for use in the lubrication Aof ydrums revoluble on shafts of other machines. y p
@ne of the objects of my invention 1s to affords the carrying of a relatively large amount of lubricating material, which is efficient in operation, which provides novel means for preventing the passage out of the drum along the shaft on which it is revoluble of oil carried by the drum, which has novel means for indicating the amount of oil to be fed at a time into the drum, Which is simple, cheap, durable, not liable to get out of order, and which `is adapted for lembodin'ient in hoist drums of types commonly used.
The novel features of my invention are hereinafter fully described, and claimed.
In the accompanying drawings, which illustrate the preferred embodiment of my invention,
Fig. 1 is a vertical sectional view ,on the line 1 1 of Fig. 2, showing my improved lubricating system as applied to a hoist drum. n i
Fig. 2 is a vertical section on the line 2 2 of Fig. i.
Fig. 3 is a section on the line 3 3 of Fig. 1.
Fig. 4 is a sectionY on the line 4 4 of Fig. 1.
Fig. 5 is a section on the line 5 5 of Fig.1. Fig. 6 is an enlarged sectional view of a portion of one of the oil slinging collars and the drive shaft. .Y
Similar reference characters designate similar parts in the different views.
1 designates the hoist drum having a hub comprising a body 2 mounted on sleeve bearing members 3, which are revoluble on a rotary drive shaft 4, the latter being adapted to be connected by clutch mechanism, notl shown with a clutch ldrum 5 encircling the shaft 4 and'fastened to one end ofthe drum 1.
The hub body 2 is provided i'vith an intermediate oil supply chamber 6 at the middle part of theY body, the ends of the latter being respectively provided with two end oil chambers 7, all said chambers encircling the axial hole oflthedrum'in which the shaft 4 is rotatable.
The body 2 is provided With inner end Walls 8 and two partition transverse Walls 9,
s,l 1926.- seriai No. 79,935'.
the latter forming the chamber 6 into three compartments, which are connected With veach othenby ductslO extending through saidpartition Walls 9, said ducts 10 being 4the chamber 6. provide a novel lubrication system which Radial ducts 12 are located in each of the Walls 8 and 9 and communicate at their outerV ends with the adjacent ducts 1() and 11.y The inner ends of the ducts 12 in each ` Wall 8 and 9 communicate with an annular groove 13, one in each of said Walls, Aand Vdisposed next the sleeve bearings 3 adjacent thereto. Each sleeve member 3 is provided with radial holes 14, some of which communicate iviththe adjacent grooves 13, and others communicating With the adjacent one of the three compartments of chamber 6.
In each end Wall 8 are yprovided spaced apart radially disposed oil ducts 15 which lead inwardly from the periphery of the adjacent oil chamber 7 and away from theY axis of the drum 1, and which at their inner ends communicateivith the adjacent ducts l2, the diameter of chamberG being greater than the diameters of the chambers -7 to permit of such arrangement. f
' As shown, the bearings 3 may have a babbittflining 3. n f
' F astened tothe outer ends respectively ,of the hub body 2 are two ring plates 16 which encircle the shaft 4 and respectively close the outer ends of the chambers 7. I
Respectively Vfastened to the shaft 4 inthe chambers`7 are two oil slingingcollarsfl7, Which are Vfastened to the shaft 4 in any manner, as by set screws18, Fig. 6. The
ing the chambers 7 being forced by; centrifugal'force, when the drum 1 is revolving, through the Yducts 15 12 andll yinto the koil 1 supply chamber 6, and when the drum is stationary, the oil in chambers 7 Will run downwardly to the lower sides of the cham-k A bers 7, and through theV ductsvl, andf 1,1
into the chamber v6'.
The oil which is in the chamber 6, will, When the drum is stationary, run through disposed recesses 19, the side walls of which converge inwardly from the periphery of ithe chamber 6 to the adjacent sleeve bearing VV3, each of the latter lhavingv some' of the radial holes 111 between the end and partition wallsl 8 and 9, sothat oil flowing downwardly from those recesses which are above thehorizontal center of the drum, when the drum 'is stationary, will flow onto the bearinlgs `3 and then through the adjacent holes 14 onto theshaftl.
Forpouring oil into the chamber 6, the
inner periphery ofthe latter is provided lwith` an inwardly extending boss 20, Fig. 1,
aiidFig. 2, which has therethrough a radial hole 21, in which is fitted a nipple 22 Vmounted in an elbow Q3, which has fitted in itiapipe 211 mounted in an exterior elbow 25,
inwhichis mounted a closure comprising a screw plug 26. The'boss 2O is preferably llocated in the longitudinal middle of the drum 1,"and communicates with the middle 'compartment ofthe chamber 6.
To determine when a proper amount of oil has been poured into the chamber 6,
through the filling means just described, the
periphery "of the chamber 6 isv provided, in the side of the chamber opposite to tliathav- "ing" the boss 20, Vwith a boss 27, which entends .inwardly from the periphery, and in which is a radial hole 28 in which is fittedv a nipple "Q9 mounted at its outer end in an elbow 30, `'which has mounted in it apipe 31, the outer l end of which is mounted'in a try cock 32 having a shut off'valve 33.
Y then tlie'oil is to be poured into the chamber 6, the drum` is disposed with the boss 27 and try cock 32 inthe lowermost position, as inFig. 1.
The boss 2O and the elbow will then be in the uppermost position. The plug 26 is removed and oil is poured into the chamber 6 through the 'elbow` 9,5,"thevalve 33 at the time being opened. ',Vvlhen oil begins 'to vflow from the try cock 32, the proper amount of oil will be in the chamber 6. The valve 33 is then closed, and the screw plug 26 replaced in the elbow 25.
W'hen the drum 1 is revolved,the oil in chamber G will form by centrifugal force in an annularslieet on the periphery of chamlplane'of the axis of the drum, will flow through the ducts 12, grooves 13 and holes 4111 onto the lshaft 111, the remainder of the oil which is on the inner periphery of the 4chamber 6, and ducts`10 and 11 and recesses 19, which arebelow the horizontal plane of the aXis of the drinn, runningto the bottom of ther chamber 6, as'shownin Fig. 1.
It will be noted that, as shown in Figs. 1 i and 3,`the peripheries of' the chambers 7 iiare inwardly toward the chiots 15 from thering alates 16 to insurethe oil beinO' forced in wardly away from the'said plates.
4vlirom'the foregoing description, it will be seen that every time the drum 1 Vstops, oil willbefed from the periphery ofthe cham ber 6 onto and into the sleeve bearings 3 and onto the shaft Zl, andwhen the drum is running oil will be forced centrifugally to the periphery of the drum, and, whether or not the drum is revolving, oil 'which has passed along the shaft l into the chambers 7, will be fed back therefrom into the chamber 6, through lthe ducts 15, 12 and 11.
Ido .not limit my invention tothe structure shown and described, as many modifications, within the scopeV of the appended claim, may be made witliout'd-eparting from the spirit of my invention.
Vhat I-claim is '1n a lubricating `system of the kind described, the combination with a drum' having a hub provided with two oil chambers at its y ends respectively and an oil supply chamber intermediate of said end chambers, said hub `having an axial hole therethrough, andprovided with means by which oil may be carriedfrom said end chambers into said inter- In testimony whereofI have signedmy l name to this specification.
