Specific embodiment
The utility model is described in detail with reference to the drawings and specific embodiments:
As shown in Figure 1 with Figure 2, the detection device of super large type bearing ring outer diameter described in the present embodiment, including
Pedestal 1, v-shaped bearing 2, handle 3 and measuring instrumentss 5, the pedestal 1 are cuboid plate, have threaded hole, the screw thread thereon
Hole is on the intermediate end face along installation measuring instrumentss direction；It is 90 ° and big bottom edge that the v-shaped bearing 2, which has shaped like two waist angles,
Open isosceles trapezoidal structure, be provided among the small bottom edge for connecting two waists installation measuring instrumentss through-hole and perpendicular to
The top end face in measuring instrumentss direction offers the threaded hole (as shown in Figure 3-4) by 4 fixation measuring instrument 5 of screw, institute
V-shaped bearing 2 is stated to be fixedly welded on the pedestal 1 of cuboid by the lower end surface on small bottom edge；As shown in Fig. 5 (a) and Fig. 5 (b), institute
The one end for stating handle 3 is threaded connector, which is fixedly connected in the threaded hole on pedestal 1, handle 3 it is another
End is for convenience of hand-held cylindrical body, and intermediate open up facilitates the through slot that rotation is tightened；The measuring instrumentss 5 pass through fixation
Screw 4 is fixedly installed in the small bottom edge through-hole of v-shaped bearing.
The method detected using the detection device of above-mentioned super large type bearing ring outer diameter are as follows: determined using 3 points
Round principle by the method for measurement of comparison outer diameter standard component to detect super large type bearing ring outer diameter deviation, specifically:
1) tested outer diameter standard component 61 is placed on platform 7 first, the platform is general plane plate, mainly
In order to enable bearing ring free state to lay flat, it is outer through measurement verification to be that 90 ° of v-shaped bearings are closely closely attached on using angle
The outer surface diameter standard component (radius R), so that the inner surface linear contact of v-shaped bearing structure is in the outer surface of outer diameter standard component,
The table point of measuring instrumentss, which is in close contact, again is fixed zeroing in outer diameter standard component outer surface, and by measuring instrumentss, that is, forms two
Supporting-point and a measurement point determine that the mode of circle completes the measurement process of comparison outer diameter standard component, measuring instrumentss zero.
2) secondly measurement of comparison is gone to be placed on the tested large-scale bearing ring on platform in the same way, by repeatedly right
Than measurement, the measuring instrumentss indicating value variation Δ after measurement of comparison outer diameter standard component returns to zero is observed, measurement data is recorded and simultaneously asks flat
Mean value.
3) finally measuring instrumentss indicating value variation Δ is brought into formula: δ=Δ/(- 1) it, is calculated and is tested especially big profile shaft
The radial misalignment δ of bearing ring outer diameter and outer diameter standard component completes the measurement of comparison to super large type bearing ring outer diameter.
Fig. 5 (a) is to zero standard part, and Fig. 5 (b) is measurement bearing parts, and R is standard component outer radii in figure, and Δ is to survey
Scale indicating value variable quantity, variation of the δ between bearing radius and standard radius are described using outside a kind of super large type bearing ring
Calculation formula specific derivation process used in the detection method of diameter size are as follows:
In conjunction with Fig. 5 (a) it is found that,
In conjunction with Fig. 5 (b) it is found that,
Then, h=(- 1) R, h1=(- 1) (R+δ), it is known that measurement expression value variation delta=h1-h=(-1)δ。
Further, be tested super large type bearing ring outer diameter and outer diameter standard component radial misalignment δ be Δ/(- 1).
