Description

SPECIFICATION Improvements in circlips The present invention relates to a circlip for axially securing an outwardly cylindrical ele-ment to an inwardly cylindrical element and to an assembly incorporating such a circlip.
For the axial securing of an outwardly cylindrical element, for example an outer race of a roller bearing, within an inwardly cylindrical element, for example a bearing housing, a circlip is usually used which lies in a groove which is cut into the bore of the inwardly cylindrical element, the frontal face of the circlip contacting the frontal face of the outwardly cylindrical element. The inwardly cylindrical element often has at its opposite side a shoulder which which contacts the other frontal side of the outwardly cylindrical element.
The groove for the conventional circlip and the shoulder require a certain amount of space in the axial direction, thus enlarging the dimensions of the parts concerned in the axial direction. This situation is particularly disadvantage when it causes an extension of the distance between the supports of a shaft which is stressed by bending forces, such as the crankshaft of an internal combustion en gine. -As a result of this, it is necessary to make such a shaft relative strong or to manufacture it from a relatively expensive material.
According to one aspect of the present invention there is provided a circlip for axially securing an outwardly cylindrical element to an inwardly cylindrical element, the circlip comprising inner and outer portions in the form of arcuate sections having relatively smaller and larger radii, the inner and outer portions being connected by means of intermediate portions.
The invention also relates to an assembly comprising an outwardly cylindrical element, an inwardly cylindrical element, and a circlip as defined hereinabove, the inner portions of the circlip being received by a first circular groove located on the circumference of the outwardly cylindrical element and the outer portions of the circlip being received by a second circular groove located on an outer portion of the inwardly cylindrical element, the inner portions and the intermediate portions of the circlip being located in recesses formed in the inwardly cylindrical element.
Thus, the circlip can be accommodated within the outer dimensions of the inwardly cylindrical element regardless of the dimensions of the outwardly cylindrical element.
The circlip may be installed and removed easily without the necessity of a special tool which is required for conventional circlips.
Preferably, the inner and outer portions of the circlip, and thus the first and second circlip grooves, lie in a common plane. A welldistributed contact with the elements to be fixed in their location and a particularly easily installation and dismantling can be obtained by a configuration with three inner and three outer portions with the circiip gap being located in one of the outer portions.
The circlip can be manufactured cheaply from spring wire having a circular cross-section.
For a better understanding of the present invention and so shown more clearly how it may be carried into effect, reference will now be made, by way of example, to the accompanying drawings in which: Figure 1 is a cross-sectional view through a crankshaft bearing along the line l-l in Fig. 2; and Figure 2 is a cross-sectional view through the crankshaft bearing along the line ll-ll in Fig. 1 In the illustrated embodiment, an outwardly cylindrical element is constituted by an outer race 1 of a roller bearing, to which bearing rollers 2, an inner race 3 and a cover ring 4 also belong. In the illustrated embodiment, an inwardly cylindrical element is constituted by a bearing cover 5 which is supported by a housing portion 6 of an internal combustion engine otherwise not shown.The inner race 3 is mounted on a crankshaft 7 of the internal combustion engine. The race 3 is urged against a shoulder 10 of the crankshaft 7 by Belleville washers 9 via an angular ring 8 and the cover ring 4. The Belleville washers 9 on their part are supported by a hub portion 11 which is secured to a tapered portion 1 3 of the crankshaft 7 by means of a nut 1 2. A shaft seal 14 is in sliding contact with the angular ring 8. A circlip 15, which may be made, for example, of spring wire having a circular cross-section, consists of inner portions 16, outer portions 1 7 and of intermediate, curved portions 18, there being three of each of the portions 16, 1 7 in the illustrated embodiment.The inner portions 1 6 lie in a circular groove 1 9 of the outer race 1. The outer portions 1 7 lie in a circular groove 20 which is cut into an outer cylindrical portion 21 of the bearing cover 5. The inner portions 1 6 and the curved portions 1 8 lie in recesses 22 of the bearing cover 5 leading from the circular groove 20 to a frontal side 23 and to a bore 24 of the bearing cover 5. A gap 25 in the circlip lies within one of the outer portions 17.
For installation purpose, the circlip 1 5 is slightly widened and moved in the direction of the arrow A over the portion 21 respectively over the outer race 1 until it snaps into the circular grooves 1 9 and 20. The circlip 1 5 is then able to secure the race 1 against axial displacement in both directions.
