SU6946A1 - Composite liner for steam bearings with annular lubrication - Google Patents

Description

The proposed composite liner for ball bearings with annular lubrication is shown in the drawing, where FIG. 1- depicts its side view, partly in longitudinal section; FIG. 2 is a front view and a cross-section along line AB in FIG. one; FIG. 3 is a top view of the lower half and crankcase; FIG. 4 is a front view thereof; FIG. 5 is a plan view of one liner; and FIG. b depicts the same as FIG. 4, for a shaft of smaller diameter.

According to the invention, the bearing consists of two separate parts: a two-half crankcase A and a liner D, the latter can be removed from the crankcase A. and replaced by another when damaged or when changing from one shaft diameter to another.

FIG. The 1.2 / 4 and 6 upper support of the second protrusion T of the upper liner B abuts against a recess in the upper half of crankcase A, while the lateral projections E (Figs 1, 3 and 5) rest in the corresponding support ball surfaces as in the upper,

and in the lower half of crankcase A, which prevents the possibility of turning the liner B into the crankcase A.

In the upper half of the liner B there are slots C (Figs. 1, 2, 4 and 6), which serve to pass the rings D and the inner recesses 3 to further follow the ring D up to the place of contact of the latter with the shaft; then ring D, the passage down through slot C on the opposite side of the lower liner D drives out of the latter and, receiving a rotational movement from the friction with the shaft, falls into the notch of the channel -K (Fig. 3) in the lower half of crankcase A, where oil at the bottom of the crankcase.

Bolts A (Fig. 1) are screwed on the holes that serve to flush and inject oil flowing through narrow channels O into the lower half of the crankcase A. Bolt M is used to screw in the hole to drain the used oil.

The subject of the patent.

Composite liner for ball bearings with annular lubrication, characterized in that the liner consists of two parts — an outer, a composite liner or crankcase A with supporting spherical surfaces and located inside its second, bearing shaft, composite, semen liner B with supporting projections G, fixed in liner A by semicircular lateral projections E, which are included in the corresponding grooves of the upper and lower halves of liner A, which liner B is made semen, in order to replace it with the same body The bearings and the same insert A to shafts of different diameters.
