Description
SPECIFICATION
Cage for a conical needle or roller bearing
The present invention relates to cages for roller or needle bearings and more particularly to the cages for conical rolling bearings.
Some known conical roller or needle bearings comprise a cage of plastics material for maintaining the spacing of the rolling elements even.
In order to ensure optimum operation, the cage must be centered relative to the rolling elements.
Further, sealing means must be provided in order to protect the rolling elements from the exterior medium.
An object of the invention is to provide a cage of moulded plastics material for a conical rolling bearing which, while it is relatively simple to produce, can be easily centered relative to the rolling elements and seals the rolling bearing in which it is provided.
The invention therefore provides a cage of plastics material for a conical rolling bearing comprising a body of frustoconical shape including cavities for receiving rolling elements and spaced at equal distances apart in the lateral surface of the body, wherein each cavity receiving a rolling element is provided with projections which retain the rolling element in the cavity, extend inwardly of the cavity and are moulded in one piece with the cage.
Further features of the invention will be apparent from the ensuing description with reference to the accompanying drawings, which are given solely by way of example and in which:
Figure 1 is an elevational and partial sectional view of the cage for a conical rolling bearing according to the invention;
Figure 2 is a sectional view taken along line 2-2 of Fig. 1;
Figure 3 is a sectional view taken along line 3-3 of Fig. 3;
Figure 4 is a partial view, taken in the direction of arrow F of Fig. 1, of a cavity provided with projections for retaining a rolling element;
Figure 5 is a partial sectional view and elevational view of a mould for producing the cage according to the invention;;
Figure 6 is a partial perspective view of an inner semi-mould shown in Fig. 5, there being shown the shape of one of the projections adapted to form, in the cage, in combination with corresponding projections provided on the outer semi-mould, the cavities for the rolling elements, and
Figure 7 is a partial elevational and sectional view of a conical rolling bearing provided with the cage according to the invention.
The cage for a conical rolling bearing shown in Fig. 1 comprises a frustoconical body 1 of plastics material, for example Nylon. Formed in the body 1, at equal distances apart, are cavities 2 for receiving rolling elements such as needles 3 (Fig. 2), said cavities opening onto the inner lateral surface 4 and onto the outer lateral surface 5 of the body 1.
As can be seen in Fig. 1, the cavities 2 are arranged to be perpendicular to the lateral surfaces of the body 1.
At each of its ends, the body 1 has, moulded in one piece therewith, a first lip portion 6, 7 for centering and sealing and adapted to cooperate with the inner ring of a conical rolling bearing which receives the cage according to the invention, and a second lip portion 8, 9 for centering and sealing and adapted to cooperate with the outer ring of this rolling bearing.
The lip portions 6 to 9 are formed by flanges of revolution provided respectively on the inner surface 4 and on the outer surface 5 of the body 1. These flanges are inclined relative to the general direction of the body 1 at a suitable angle so as to ensure their centering and sealing functions. The inner flanges 6 and 7 extend toward the axis of the cage and the outer flanges 8, 9 extend away from this axis.
As can be seen in Figs. 1, 2 and 4, each cavity 2 for receiving a needle 3 has a generally rectangular shape and includes at each of the junctions of two of its walls two projections 10, 1 1 which extend inwardly of the cavity and are adapted to maintain the needle 3 in position in the latter. As can be seen in
Figs. 1 and 4, the projections 10 and 11 have different shapes owing to production problems which will be explained hereinafter when the method for producing the cage according to the invention is described.
As can be seen in Fig. 3, which is a sectional view similar to Fig. 1 but in a part of the cage according to the invention devoid of cavities, the contour of the retaining projections 10 and 11 is maintained throughout the periphery of the cage.
It can be seen in Fig. 4 that the arrangement and the nature of the projections 10 and 11 provided at each end of the cavity are symmetrical relative to the centre of the latter.
The mould shown in Fig. 5 comprises a cavity 15 having the shape of the cage for conical rolling bearings to be produced, said cavity being defined by two shells 16 and 17 which are fitted one inside the other in a direction parallel to the axis of the cage to be obtained.
As shown better in Fig. 6, the inner shell 1 6 of the mould in Fig. 5 has a frustoconical lateral surface 18 which is extended, at its end of large diameter, by a narrow frustoconical surface 19 adapted to form the inner side of the flange 7 (Fig. 1) and, at its other end of smaller diameter, by a cylindrical surface 20 which is connected to the frustoconical surface 18 by a step 21 whose thickness is adapted to define the region of revolution in which the projection 11 of the corresponding cavity 2 will be formed.
In the region of each cavity 2, the inner shell 16 has a projecting portion 22 having the general shape of a triangular prism whose surface 23 opposed to the frustoconical lateral surface 18 is parallel to the axis of the cage to be obtained, ignoring the moulded part stripping draft of the mould. The end surface 24 of the projecting portion 22 makes, with the direction in which the shells 16, 17 fit one inside the other, an angle which is complementary to the semi-angle at the apex of the lateral frustoconical surface 18 so that the corresponding cavity is oriented in the manner indicated hereinbefore.
The apices of the projecting portion 22 which form its end surface 24 have triangular chamfers 25 in the region of its lateral surface 22 and rectangular chamfers 26 in the region of the junction between the projecting portion 22 and the cylindrical portion 20 of the lateral surface of the mould shell 16. The triangular chamfers 25 form, when moulding, the projections 10 and the rectangular chamfers 26 form the projections 11 of the cavities 2.
The shell 17 has a contour complementary to that of the shell 16. In the region of each cavity 2, it has a projecting portion having a triangular prismatic shape 28 whose point points toward the end surface 24 of the projecting portion 22 of the inner shell 16 and whose end surface 29, corresponding to the aforementioned surface 24, is in facing relation to the point of the projecting portion 22. In the same way as the shell 16, the outer shell 17 has a lateral surface of generally frustoconical shape for defining the outer surface of the cage to be obtained. Two corresponding projecting portions 22 and 28, one of which pertains to the inner shell 16 whereas the other pertains to the outer shell 17, are in contact by their outer lateral surfaces, such as the surface 23 of the projecting portion 22, this contact surface being designated by the reference numeral 30 in Fig. 5.
It will be observed that it passes through the opposed apices of a volume of generally parallelepipedic shape that the two projecting portions 22 and 26 form together. This contact surface is parallel to the direction of relative displacement of the shells 16 and 17 and to the axis of the cage to be obtained.
The mould just described has the advantage over the mould heretofore constructed for forming complex parts, such as a conical rolling bearing cage, of being made in solely two parts which are displaceable when stripping the mould in a direction parallel to the axis of the part to be formed. The triangular shape of the chamfers 25 and the rectangular shape of the chamfers 26, the latter also extending in a direction parallel to the direction of relative displacement of the shells 16 and 17, provide the cavities 2 with projecting portions which, while being apparently in the form which is the opposite of a draft and thus hindering stripping from the mould, do not in fact constitute an obstacle to the stripping
Further, in order to permit the stripping of the part from the mould, the portions 15a and 1 sub of the cavity 1 5 located beyond the cavities for moulding the flanges 6, 8 and 7, 9 of the cage, are made cylindrical in shape.
In the moulding cavity defined by the assembly of the shells 16 and 17 of Fig. 5, the sole portions which would prevent the stripping of the mould are formed by the surface 19 of the shell 16 and by the corresponding surface 31 of the shell 17, the surface 19 defining the inner sealing flange 7 and the other surface defining the outer sealing flange 8 of the cage shown in Fig. 1.
However, bearing in mind the fact that these flanges are thin, it will be understood that, upon stripping the mould by separation of the shells 16 and 17 in the general direction of the axis of the cage to be obtained, the surfaces 7 and 8 will, owing to the resilience of the material of the cage subsequently resume the initially-formed shape.
Fig. 7 is a sectional view of a conical rolling bearing provided with a cage according to the invention. It can be seen in this Figure that the inner flanges 6 and 7 of the cage, in bearing against the opposed ends of the rolling surface of the inner ring 35, both centre and seal the cage relative to the ring. Likewise, the outer flanges 8 and 9 bear against the opposed ends of the rolling surface of the outer ring 36 and perform the same centering and sealing functions. Owing to this arrangement, the body 1 of the cage is centered relative to the needles 3.
Further, in the embodiment shown in Fig.
7, the inner ring 35 and outer ring 36 of the rolling bearing have at the ends of their rolling surfaces circular flanges 37 and 38 respectively against which the inner flanges 6 and 7 and the outer flanges 8 and 9 of the cage bear and thereby maintain the inner ring axially in position relative to the outer ring.
This axial maintenance of the inner and outer rings may also be ensured by the cooperation of the flanges with chamfers provided at the end of the rolling tracks of the inner and outer rings.
The cage just described has a number of advantages over the cages of the prior art.
It considerably facilitates the assembly of the rolling bearing for which it is provided, since, when it is placed in position in the outer ring, it centres itself and ensures centering of the rolling elements it carries.
It also ensures centering of the inner ring of the rolling bearing.
The presence of the centering flanges more over maintains the cage centered relative to the rolling elements in operation of the bearing.
Owing to the fact that it is produced by means of a mould comprising two shells, the major part of whose junction surfaces are parallel to the direction of the stripping of the mould, the cage may include inner and outer retaining projections for the rolling elements.
Consequently, it provides an improved retention of the needles, which is essential in particular in the case of an intermittent or alternating movement of the bearing.
