この発明は1台の装置でころがり軸受のすきま測定と回
転精度測定とを該軸受をセット換えすることないこ測定
可能とした測定装置の改良に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a measuring device that allows a single device to measure the clearance and rotational accuracy of a rolling bearing without changing the bearing.
従来の測定装置では、回転精度とすきまを測定するには
別々の装置を用意しなけれならず、特に大形の軸受を測
定するにはセット換えするのに作業が厄介であった。With conventional measuring devices, separate devices must be prepared to measure rotational accuracy and clearance, and it is especially troublesome to change the set when measuring large bearings.

装置について発明をなし、特許出願を行った(昭和$年
特許藤第111769号)。In addition, when measuring radial clearance, it is necessary to apply the measurement load from above and below, which not only makes it difficult to apply an even radial load to the bearing to be measured, but also makes it difficult to place the transferred body on the load side correctly on the raceway surface of the inner and outer raceways. It was also difficult to bring them into contact, and when manual operation was carried out, it was inevitable that the load would fluctuate. It is also used when measuring rotational accuracy. Because the inner ring had to be rotated and the outer ring had to be rotated depending on the fixed bearing ring, the ikioi device became complicated. The applicant first stops the rotation of the outer ring (or inner ring) of the bearing to be measured, and then rotates the inner ring (
Invented and patented a measuring device that made it possible to measure the gap in one set of bearings to be measured by rotating only the bearing (or outer ring) and making it possible to move the rotary table that holds the bearing to be measured. An application was filed (Showa $ year patent Fuji No. 111769).

from above and rotate the rotary table 14 several times to read the indicated value of the measuring stylus 32. Thereafter, the rotary table is rotated in the opposite direction to return to its original angular position. Next, as shown by the broken line in FIG.
180o to the right to the rotating table while keeping it relatively fixed.
When reversed, the measuring element 32 comes into contact with the outer ring surface of the outer ring from below. After rotating the rotary table 14 in this state, it is reversely rotated to return to the original angular position, the indicated value of the measuring stylus 32 is read, and the value of the radial clearance is calculated based on the constant value on both sides. To measure the axial clearance, a pair of arms 31 are provided at the tips of a pair of arms 31 that protrude from the outer end of the rotary table 14 at symmetrical positions with respect to the axis of the spindle shaft 15, as shown by solid lines in FIG. Measuring head 3
2 is brought into contact with the lower end surface of the outer ring 33 of the bearing, and the rotary table 14 is rotated.

に定がきわめて容易となった。Then, the measuring element 32 rotates together with the rotary table 14, and measurement is performed. Next, the rotary table 4 is rotated 180 degrees as shown by the dotted line in FIG.
Rotate 4 and take measurements. Find the difference between the maximum and minimum values of the measurement values obtained with each probe, and average these to obtain the measurement value. The radial clearance can also be measured by bringing the pair of probes 32 into contact with the outer ring surface and moving the rotary table 14 as shown in FIG. 3. As mentioned above, in this invention, since the rotary table can be mounted on the head and neck, it is possible to measure internal and external run-out and clearance with one device, and there is no need to change the bearing settings, so it is particularly easy to perform the measurement. became.

遊隙が測定誤差となって現われることはない。Furthermore, when measuring the clearance, especially in large bearings, it is not necessary to apply measurement loads to the bearing from above and below, and an even radial load can be obtained. Furthermore, even if the rolling elements are located in an abnormal position before measurement, one bearing ring is fixed and the other bearing ring is rotated, so the frictional force at the contact part at the abnormal position is removed. This allows the rolling body to be brought into proper contact with the raceways and surfaces of the inner and outer rings, allowing for highly accurate measurements. Furthermore, when measuring the axial clearance, the probe was protruded from the outer side of the rotary table and brought into contact with the end face of the outer ring of the bearing, so the rotary table and the inner ring of the bearing were directly fixed. Even if there is a play between the spindle and the extra-axial muscle that has been carefully placed, the play does not appear as a measurement error, unlike when the arm body 31 and the probe 35 are attached to the outer cylinder.

。In addition, since the probe is located near the measurement site, the arm body 31 becomes short, and even if vibration or deflection occurs at the measurement site,
Since these errors can be minimized, accurate measured values can be obtained. In addition, by providing a pair of measuring elements symmetrically with respect to the wisteria line of the spindle shaft as in the example, highly accurate measured values can be maintained even if the bearing to be measured is not set correctly. It greatly contributes to high-accuracy measurement of bearings and automation of measurements. Additional Relationship This invention is disclosed in Japanese Patent No. 1167310 (Japanese Patent Publication No. 5716
2001), “Rotational accuracy and clearance of rolling bearings.
Regarding the improvement of the cylindrical body and rotary table, a pair of axial clearance measuring parts were installed at the outer diameter end of the rotary table, instead of having a clearance measuring part attached to the joint body. Even if there is play between the spindle shafts to which the spindle is attached, or if the bearing to be measured is improperly set, highly accurate measured values can be obtained without being affected by these.
