Improvements in or relating to Ball Bearings for Shafting.
We ENGELBERT FRIES and WILHELM HÖPFLINGER, both of Schweinfurt a/M
in the Empire of Germany, Manufacturers, do hereby declare the nature of this
invention and in what manner the same is to be performed to be particularly
described and ascertained in and by the following statement:-
This invention relates to ball bearings and consists in certain improvements
therein as hereinafter described and claimed, rendering them easily applicable to
and suitable for rotary shafting, whether horizontal, vertical or inclined.
In the annexed sheet of drawings, Fig. 1 is a longitudinal central section of the
improved ball bearing as applied to a horizontal shaft and illustrating two forms of
construction, Fig. 2. is a plan of said bearing and shaft, Fig. 3 is an end view
thereof from either end with one of the members of the bearing removed, Fig. 4 is
an end view from the right of Fig. 1 with said member in place.
The bearing box b, which may be of cast iron and be made in one or more pieces
with a passage way therethrough for the shaft a to occupy, preferably without
contact with the bearing box, is suitably flanged or otherwise made to receive one
at each end two steel rings c c forming respectively annular tracks for the balls f.
The rotary members or journals of the bearings usually termed cones d d are made
so that they can be slid along the shaft a and be caused to firmly grip the latter
after they have been adjusted respectively to bear against the series of balls fat
each end of the bearing box.
We do not confine ourselves to any particular method or means for causing the
cones d d to grip tightly upon the shaft a but may use any such means or method;
to the left of Figs 1 and 2 we have shown on the back of the cone a slightly
tapered screw threaded sleeve d' with a slit or slits as at s in direction parallel to
its axis. e is a screw threaded nut adapted to engage the threads on sleeve d' and
by being screwed up thereon compress said sleeve into firm frictional engagement
with the shaft a. To the right of Figs. 1 and 2 and in Fig. 4 we have illustrated
an alternative construction in which the sleeve d' provided with a slit s carries a
lug along each side of said slit. These lugs may be forced together by means of
a screw 7 or bolt and nut in the known manner.
Having now particularly described and ascertained the nature of this said
invention and in what manner the same is to be performed we declare that what
we claim is ;-
The improvements consisting in :—
1. The combination with a bearing body having at its ends annular bearing
faces for balls with two counter faces d d adapted to be slid upon the shaft a
lengthwise thereof and brought into gripping contact with said shaft for the
purpose set forth.
2. The combination with the bearing body b, of steel bearing rings e o in the
ends thereof, balls ff and counter bearings d d with means for bringing same into
gripping engagement with shaft a for the purpose set forth.
3. The construction, in the bearing herein described, of 'the counter bearings d d
as cones having extending from their bases slit sleeves d' adapted to be compressed
onto the surface of shaft such as a for the purpose described.
Dated this 1st day of October 1894.
