Description

SPECIFICATION A mounting device for antifriction bearings The present invention relates to a device for mounting antifriction bearings in place.
Most common of the conventional methods of mounting antifriction bearings consists in first setting the outer race of the bearing in the bore provided in the housing of a machine, then bringing one end of the outer race into contact with the peripherally stepped portion formed on the inner periphery of the housing's bore and blocking the other end thereof with a stopper ring set in the inner periphery of the housing's bore to thereby prevent displacement thereof along the axial direction with respect to the bearing.
This method, however, is troublesome in that machining is required for forming the peripherally stepped portion in the inner periphery of the housing and also for providing an inner circumferential groove for fixing the stopper ring. Moreover, the method necessitates designing the housing bore taking into consideration an allowance in length and thickness for accommodating the stopper rings at one or both ends thereof.
A typical embodiment of the bearing mounting device disclosed therein is shown in Figure 1C of U.S. Patent Specification No.
4,054,999. Both ends of an outer race 1 20 of the double cup type having symmetrical tapered raceways 10 set in a housing's bore 1 24 are checked against displacement by snap rings 1 26 fitted in circumferential grooves 1 28 formed in the inner periphery of the bore 1 24.
The circumferential grooves 1 28 are required to have sufficient strength to ensure against axial displacement of the bearing's outer race 1 20 in the bore by means of the snap rings 1 26 and also to withstand the shaft thrust applied to the bearing. The body of the housing is, therefore, required to be longer than the bearing's outer race, hence it is difficult to reduce the size of the housing.
In the case of a bearing with its outer race designed as a double cup thinner at both ends, the condition is such that the inner diameter of the snap ring is smaller than the inner diameter of both ends of the outer race, and the bearing's rollers interfere with the inner periphery of the snap ring to obstruct smooth rotation of the bearing.
It is, therefore, the object of the present invention to provide a mounting device for antifriction bearings which eliminates the aforementioned shortcomings of the prior art.
The present invention consists in a bearing mounting device comprising; a first circumferential groove provided in the outer peripheral face of the outer race of an antifriction bearing, a second circumferential groove provided in the inner periphery of the bore of a member in which said bearing is mounted and aligned with said first circumferential groove in the outer race, an opening provided in part of the bottom of said first circumferential groove and communicating with the interior of said outer race, a resilient fixing means inserted peripherally into said first and said second circumferential grooves striding both, and an end portion of said fixing means extending into said outer race through said opening in said first circumferential groove.
This fixing means is made accessible from inside the outer race for the mounted bearing so as to be easily demountable from inside the bore of the housing.
Furthermore, the manner of mounting the bearing is simplified and the size of the housing can be reduced. Also it provides for, for instance, double row taper roller bearing with the ends of its outer race being thin, a device enabling mounting thereof safely in a housing without interfering with the bearing's operation.
Figure 1 is a front view in vertical section of an embodiment of the present invention, Figure 2 is a side view in vertical section taken along the line ll-ll in Figure 1, Figure 3 is a fragmentary side view in vertical section similar to Figure 2 of a modified embodiment, Figure 4 is a side view in vertical section similar to Figure 2 of another example of fixing means, Figure 5 is a side view in vertical section similar to Figure 2 showing a still further example of fixing means, Figure 6 is a fragmentary side view in vertical section of a modification of Figure 5, Figure 7 is a fragmentary sectional view showing the dimensions of the circumferential grooves in the outer race and the housing as well as the fixing means of Figures 5 and 6.
The embodiment shown in Figure 1 is of a device for mounting wheel hub bearings. The mounting device shown comprises a housing 1 having an axial bore 1 a, a double cup outer race 2 of a double row taper roller bearing, taper rollers 3, inner races 4 and a retainer 5 for each taper roller. An axle 6 is tightly mounted in the inner race 4.
The outer peripheral face of the outer race 2 (central zone in the outer periphery of outer race in the embodiment) and the inner peripheral face of the bore la of the housing 3 have formed therein opposed circumferential grooves 7 and 8 respectively.
The circumferential groove 7 in the outer periphery of the outer race 2 has formed therein at an arbitrary point an opening 10 communicating with the bearing interior.
As shown in Figure 2, there is provided a substantially C-sectioned fixing means 9 extending circumferentially around and engaging in both circumferential grooves 7 and 8 with one end 11 thereof bent hookwise to ward the inside of the outer race 2, and the hooked end 11 of the fixing means 9 extends into the bearing interior through the opening 10 provided in the circumferential groove 7.
The fixing means 9 is formed of a bendable resilient material and its cross-section is rectangular as shown in Figure 1. Furthermore, the outer diameter of the fixing means 9 is larger than that of the outer race 2, while its inner diameter is smaller than the outer diameter of the outer race 2, and the radial thickness of the fixing means 9 is dimensioned to enable its mounting in the circumferentail groove 7 of the outer race 2.
The sectional shape of the fixing means 9 is not necessarily rectangular and can equally well be circular or oval. The material of the fixing means 9 may be formed of any resilient material such as metals, non-metals or plastics.
The cross-sectional shape of the opening 10 may, besides being tapered as shown in Figure 2, be substantially tangential with respect to the inner periphery of the outer race 2 as shown in Figure 3 as opening 1 Oa so as to facilitate insertion of the fixing means 9 in the outer race 2.
As shown in Figure 4, the fixing means 9a may have its radial thickness increased over the fixing means 9 of the embodiment shown in Figure 2 in order to improve rigidity. To make the fixing means 9a easily bendable as it is inserted or pulled out of the circumferential groove, the fixing means 9a has a plurality of radial slits or cutouts 1 2 provided in the inner periphery at equal intervals. The end 11 of the fixing means 9a is bent toward the inside of the outer race and has formed therein an aperture 11 a provided to facilitate removal. The same as shown in Figures 1 and 2, the end of the fixing means 9a in which aperture 11 a is formed extends into the bearing interior through the opening 10 provided in the bottom of the circumferential groove 7.
The aperture 11 a is not absolutely necessary, and may be substituted by a hook formed at the end of the fixing means 9a.
Now will be described the manner of mounting the bearing in the bore of the housing and demounting it therefrom with reference to the embodiment shown in Figures 1 to 4.
First described is the manner of mounting the bearing in the bore of the housing 1.
Radially resilient fixing means 9 or fixing means 9a is positioned in advance in the circumferential groove 7 of the outer race 2, and the hooked end 11 or the end having an aperture 11 a therein is caused to extend into the bearing interior through the opening 10 or 10a. The outer peripheral portion of the fixing means 9 or 9a is then projecting above the circumferential groove 7 of the outer race 2.
When the outer race 2 with the fixing means 9 or 9a positioned thereon (in the circumferential groove 7 thereof) is then positioned inside the inner periphery of the housing 1, the fixing means 9 is embedded in the circumferential groove 7 of the outer race 2. The outer race 2 is then further pushed into the housing bore until the circumferential groove 7 aligns with the circumferential groove 8 in the inner periphery of the housing bore, and thereupon the fixing means 9 or 9a with its radial resilience engages in the circumferential groove 8. Of course, the inner peripheral portion of the fixing means 9 our 9a is engaged in the circumferential groove 7 of the outer race 2. The outer race 2 is thus automatically fixedly mounted in the bore of the housing.
In order to demount the bearing from the bore of the housing 1, the hook-shaped end of the fixing means 9 or 9a or the aperture 11 a in one end thereof extending into the bearing interior through the opening 10 or 1 0a is hooked by a tool to be pulled out windingwise, and the outer race 2 is then removed from the bore of the housing 1.
Since the fixing means 9 or 9a is now removed, the outer race 2 is no longer restrained in the housing 1, and can be demounted without any difficulty.
In the embodiment shown Figures 1 through 4, the outer peripheral portion of the fixing means 9 or 9a set in the circumferential groove 7 of the outer race 2 projects above the circumferential groove 7 all around its periphery and the outer race 2 is pressed into the bore of the housing 1 in this condition, but since the fixing means 9 or 9a is then freely movable radially in the circumferential groove 7, the extent of projection of the fixing means 9 or 9a beyond the peripheral face of the outer race 2 is not necessarily uniform around the periphery.Hence, according to the shape of the chamfered edge 16 of the housing bore 1 a, it is possible that the fixing means 9 or 9a is caught by the chamfered edge 1 6 where the projection of its outer periphery is increased to interfere with proper embedding of the fixing means 9 or 9a in the circumferential groove 7 of the outer race 2.
Thus, there is also provided a modified construction as shown in the embodiment of Figure 5.
Shown in Figure 4 is a fixing means 1 3 of wavy or undulating form, which is improved alternative of the above described fixing means 9. The sectional form of this fixing means 1 3 is also rectangular, and is formed wavy along the periphery with its one end bent radially inward of the outer race with an aperture 11 a to facilitate removal of the fixing means 1 3. The same as in the aforementioned embodiment, one end thereof has the aperture 11 a therein extending inward of the outer race through the opening 10 provided in the bottom of the circumfereritial groove 7 of the outer race.
The principle of mounting the bearing by the fixing means 1 3 is, as is easily understood, that the wavy fixing means alternately crossing the boundary between the circumferential groove 7 of the outer race 2 and the circumferential groove 8 of the housing 1 maintains the opposing positions of these circumferential grooves 7 and 8 unaltered.
To describe it in greater detail, the individual crests 13a, 1 3a on the inside of the wavy fixing mens 1 3 come into contact with the bottom of the circumferential groove 7 of the outer race, while the individual crests 13b, 1 3b on the outside thereof are either in or out of contact with the base of the circumferential groove 8 of the housing 1, the fixing means 1 3 thus serving the aforementioned engaging function. The dimensional relationships between the fixing means 1 3 and the circumferential grooves 7 and 8 are as follows as seen from Figure 7.
With h, = Depth of housing's circumferential groove 8 h2 = Depth of outer race's circumferential groove 7 t = Thickness of fixing means 13, t, = Extent of projection above outer peri phery of outer race of fixing means 13, it is essential that the conditions of h2 > t and t, > O be always be satisfied.
The fixing function is attainable when the relation between h, and t is h, > t, h, = t as well as h, < t.
for h2 > t and > 0.
The sectional shape of the opening 10, besides those illustrated as 10 and 1 Oa, may be as well radially parallel as shown in Figure 6.
The aperture 11 or 11 a may be substituted by a hook as shown in Figures 1 and 2.
The manner of mounting or demounting the bearing in or from the bore of the housing in the embodiment shown in Figure 5 is the same as in the embodiment shown in Figures 1 to 4.
In the case of the fixing means 13, wavy as it is, its multiplicity of crests 1 3a and 1 3b on the outside alone are caused to project uniformly beyond the outer periphery of the outer race 2 when it is set in the circumferential groove 7 of the outer race, hence, when the bearing is mounted in the bore 1 a of the housing 1, the individual crests 13b, 136 can be embedded easily and securely in the circumferential groove 7 guided by the chamfered edge 1 b. There is, therefore, no possibility of the fixing means 1 3 being caught by the chamfered edge 1 b of the housing 1 a so as to interfere with the embedding of the fixing means 1 3 in the circumferential groove 7 of the outer race 2, and the bearing can be easily mounted in the bore of the housing 1.
Also positional engagement of the fixing means 1 3 with the circumferential grooves is feasible even if the thickness of the fixing means t is not large enough to astride both circumferential grooves 7 and 8.
Also, even if the sectional dimensions and resilience of the fixing means 1 3 are small, its effect to engage the circumferential grooves 7 and 8 is sufficient if only its shearing stress is ample. It is advantageous in that the work is facilitated when the fixing means is pulled out by the aid of a tool in a winding mode in order to take the bearing out of the housing.
(Then either or both of the inner race 4 and the rollers 3 are removed to evacuate half the space inside the outer race 2.) In the embodiments shown in Figures 1 to 7 the length of the fixing means 9, 9a or 1 3 is less than the circumference of the circumferential groove 7, but it is generally sufficient if its length is more than 1/2 the circumference.
According to the present invention, it is not that both ends of the outer race are fixed in the housing by means of the snap rings set in the two grooves provided in the inner periphery of the bore of the housing respectively as is the case with conventional bearing mounting device, hence no excessive length is required of the housing for forming the grooves for carrying and holding the aforementioned snap rings where corresponding to both ends of the bearing in the housing.
Since the work of forming grooves in the bore of the housing for accommodating shoulders or snap rings is obviated, the axial length of the housing can be reduced substantially.
The embodiments shown here are all for double row taper roller bearings, but, needless to say, the mounting device of the invention can be effectively applied to other types of bearings such as double row angular ball bearings.
