Embodiment
With reference to accompanying drawing, the enforcement mode of the dimension measurement method of the guide wheel of the self-aligning roller bearing of the present invention is described in detail.
It it is the guide wheel used in self-aligning double-row roller bearing by the guide wheel of the dimension measurement method measurement size of present embodiment. First, with reference to Fig. 1, the structure of the self-aligning double-row roller bearing with guide wheel is described.
The self-aligning double-row roller bearing of Fig. 1 have interior take turns 1, foreign steamer 2, freely to rotate be configured in interior take turns between 1 and foreign steamer 2 two row spherical rollers 3, take turns the maintenance frame 4 keeping two row spherical rollers 3 between 1 and foreign steamer 2 interior and be configured between two row spherical rollers 3 and guide the guide wheel 5 of spherical roller 3.
Orbital plane 1a, the 1a being formed with 2 row spherical rollers 3 at the interior periphery taking turns 1, about interior take turns 1 external diameter, central part is formed greatly than axial both ends. Further, the inner peripheral surface of foreign steamer 2 be provided with 2 row one sphere orbital plane 2a, this sphere orbital plane 2a with interior take turns 1 orbital plane 1a, 1a relative.
Further, at the axial both ends of the interior periphery taking turns 1, there is flange 7,7 towards radial outside is projecting. The interior side of flange 7,7 and the end face sliding contact of spherical roller 3,3, as guiding and keep the face of spherical roller 3,3 to play a role.
And, it is also possible to it is configured with the lubricant such as lubricating oil, lubricating grease being formed in the interior bearing interior space taken turns between 1 and foreign steamer 2. And, it is also possible to adopt the structure not having and keeping frame 4 and flange 7,7.
Here, further the shape of guide wheel 5 is described in detail. As shown in Figure 1, cross-sectional shape when being cut off by the plane orthogonal with circumference of guide wheel 5 is roughly trapezoidal (such as isosceles trapezoid). That is, the inner peripheral surface 5a of guide wheel 5 is parallel with periphery 5b, and and the interval of two sides 5c, 5c of end face sliding contact of spherical roller 3 reduce gradually (5c, 5c are tapered in two sides) towards radially inner side.
About the size of this guide wheel 5, it is (with reference to Fig. 2) that be managed due to the width W of inner peripheral surface 5a, the width of periphery 5b and two sides 5c, 5c angulation �� (being designated as below " taper angle theta "), so these sizes of manufactured guide wheel 5 are measured.Below, the measuring method of these sizes is described.
For the width of periphery 5b, it may also be useful to the common measuring appliance such as vernier callipers or micrometer just can easily be measured.
For the width W of inner peripheral surface 5a, due to the interference of the side 5c at guide wheel 5, it may also be useful to the common measuring appliance such as vernier callipers or micrometer can not directly be measured accurately, so being measured by the dimension measurement method of present embodiment.
First, respectively the width (interval of two sides 5c, 5c) of the guide wheel 5 at different 2 the height location places of the radial distance of the inner peripheral surface 5a from guide wheel 5 is measured. If the width of the guide wheel 5 at the height location place that the radial distance from inner peripheral surface 5a is the width of the guide wheel 5 at the height location place of H1 is W1, radial distance from inner peripheral surface 5a is H2 is W2 (with reference to Fig. 2). Size from radial distance H1, H2 of inner peripheral surface 5a is not particularly limited, and all can adopt arbitrary size.
Next, substitute into following formula (1) by from radial distance H1, H2 of inner peripheral surface 5a and width W 1, the W2 of guide wheel 5, calculate the width W of inner peripheral surface 5a.
W=(H2 W1-H1 W2)/(H2-H1) ... (1)
Further, taper angle theta also can calculate according to from radial distance H1, H2 of inner peripheral surface 5a and width W 1, the W2 of guide wheel 5. That is, substitute into following formula (2) by from radial distance H1, H2 of inner peripheral surface 5a and width W 1, the W2 of guide wheel 5, calculate taper angle theta.
��=2tan-1{ 1/2 �� (W2-W1)/(H2-H1) } ... (2)
By the dimension measurement method of such present embodiment, it is possible to high precision and easily measure width W and the taper angle theta of the inner peripheral surface 5a of guide wheel 5. Therefore, if using the dimension measurement method of present embodiment, then can carry out processing in the manufacture scene of guide wheel and carry out dimensional measurement.
(embodiment 1)
The width W 1 of guide wheel 5, the measuring method of W2 do not limit especially, it is possible to use the common measuring appliance such as vernier callipers, micrometer to measure, but the survey 10 of the needle-like that front end as shown in Figure 3 also can be used sharp-pointed is measured. That is, guide wheel 5 is clamped from both sides by surveying 10 by 2, it is possible to measure width W 1, the W2 of guide wheel 5. And, if measuring result being substituted into upper formula (1), (2), then can obtain width W and the taper angle theta of the inner peripheral surface 5a of guide wheel 5. If using the survey 10 of needle-like as shown in Figure 3, then measuring accuracy is high precision.
(embodiment 2)
The width W 1 of guide wheel 5, W2 can also use the survey 20 that front end as shown in Figure 4 is spherical to measure. Owing to front end is spherical, so not easily making the side 5c of guide wheel 5 impaired when measuring. Further, owing to the front end of survey 20 is not easy to wear, even if so long-time continuing uses survey 20, being also not easy generation measuring error.
But, when using the survey 20 that front end is spherical to measure, as shown in Figure 5,6, owing to survey 20 contacts in the position of the central shaft of deviation survey 20 with the side 5c tilted, so the measuring result of the width W 1 of guide wheel 5, W2 can be produced error.
Such as, when the width W 1 of guide wheel 5 at the height location place to the radial distance from inner peripheral surface 5a being H1 is measured, from Fig. 5,6, contact at the height location place being the high �� h of the height location of H1 than the radial distance from inner peripheral surface 5a with side 5c owing to surveying 20, so at the height location place from the radial distance of inner peripheral surface 5a being H1, survey 20 not contact with side 5c but separate, 2 �� �� bigger than the width W 1 of reality can be exportedWValue as observed value.Further, by Fig. 5,6 it will be seen that error 2 �� ��WSize change according to the size of taper angle theta.
Therefore, when measuring the width W of inner peripheral surface 5a of guide wheel 5, it is necessary to error is corrected. If the true value of the width of guide wheel 5 is W1, W2, the observed value that comprises error is W11, W12, then W1=W11-2 �� ��W, W2=W12-2 �� ��W. If these 2 formulas are substituted into upper formula (1), then become following formula (3), it may also be useful to this formula (3), it is possible to calculate the width W of the inner peripheral surface 5a of guide wheel 5 according to observed value W11, W12 of comprising error.
W=(H2 W11-H1 W12)/(H2-H1)-2 �� ��W��(3)
Further, error delta w following formula (4) represents (with reference to Fig. 7). R in formula (4) is the radius-of-curvature of the spherical front end of survey 20, and �� nom is the taper angle theta of guide wheel 5, is the accompanying drawing value of the target value manufactured as guide wheel 5.
�� w=R sin (�� nom/2) tan (�� nom/2)-{ R-R cos (�� nom/2) } ... (4)
For the taper angle theta of guide wheel 5, it is possible to by observed value W11, W12 substitution of error calculating in formula (2) by comprising.
The shape of the front end surveying 20 in example 2 is spherical, but the shape that also can use front end be spherical beyond the survey head of shape measure. The shape held before use be spherical beyond the survey head of shape when, sometimes also need similarly to Example 2 error to be corrected. The content of correction is different according to the shape of front end, and also different according to the dimensional precision wanting to try to achieve. In addition, according to the shape of front end and the dimensional precision wanting to try to achieve, certainly have, in the measurement using survey head, the situation needing measuring method to be made an effort.
And, embodiment 1,2 any one in, the shape (cross-sectional shape when being cut off by the plane orthogonal with circumference of guide wheel 5) of the guide wheel 5 width W and the taper angle theta of inner peripheral surface 5a measured is not limited to the isosceles trapezoid shown in Fig. 2. Such as, as shown in Fig. 8��Figure 10, a part of chamfering in 4 angles of guide wheel 5 can also. Fig. 8, Figure 10 are both sides' chamferings at 2 angles of periphery side, and Fig. 9 is a chamfering in 2 angles of periphery side. Can also be different from Fig. 8��Figure 10, it is possible to be the angle chamfering of inner peripheral surface side, it is also possible to be both all chamferings at the angle of inner peripheral surface side and the angle of periphery side.
And, as shown in Fig. 8��Figure 10, can according to formed the radial direction along self-aligning roller bearing plane mode to the angle of periphery side design chamfering (that is, cross-sectional shape when being cut off by the plane orthogonal with circumference of guide wheel 5 is hexagon), can also according to the patten's design chamfering of formation curved surface.
And, the shape of guide wheel 5 is when seeing with cross-sectional shape when being cut off with the circumferential orthogonal plane of guide wheel 5, periphery can also be linearly shape (with reference to Fig. 2,8,9), it is also possible to be the shape (with reference to Figure 10) of the convexly circular arc shape of (or recessed shape can also).
Even if when these shapes, it is also possible to use the dimension measurement method of present embodiment the width W of inner peripheral surface 5a and taper angle theta to be measured. Further, even the guide wheel of the shape beyond the shape shown in Fig. 2 and Fig. 8��Figure 10, it is also possible to use present embodiment dimension measurement method the width W of inner peripheral surface 5a and taper angle theta are measured.
