たジャーナル軸受の外輪回転装置に関する。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an outer ring rotation of a journal bearing suitable for judging the degree of damage of a roller of a journal bearing which is fitted to journals at both ends of a wheel axle of a railway vehicle without disassembly by vibration inspection. Related to the device.

Description of the Related Art As shown in FIG. 5, this type of journal bearing 1 is a roller bearing in which cylindrical rollers 4 are arranged in a double row between an inner ring 2 and an outer ring 3, and both ends of a wheel shaft 5 are provided. The inner ring 2 is fitted to and attached to the journal portion 6 of the above.

た。[0003] Since the journal bearing 1 is an important part for transmitting the load of the vehicle body to the rotating wheel set 5, it is necessary to always maintain a normal operating state by regular inspection. Conventionally, the journal bearing 1 has been visually inspected by withdrawing the bearing 1 from the journal portion 6 of the wheel axle 5 and disassembling it. Non-decomposition inspections, which detect flaws while attached to the wheelset, have come to be performed.

損傷程度を判別するのである。That is, as shown in FIG. 6, a wheel shaft 5 is placed on a roller, and the outer ring 3 of the journal bearing 1 fitted to the journal portions 6 at both ends thereof is fixed with a V-block or the like, and the pinion gear is mounted. Power belt wrapped around 9
It drives and rotates the wheel set 5 to a required number of rotations. That is, the inner ring 2 (see FIG. 5) of the journal bearing 1 is rotated.
Then, the vibration pickup 11 attached to the end face of the journal portion 6 of the wheel axle 5 detects a vibration in a specific frequency range generated from the roller 4 of the journal bearing 1, and converts the detection signal into a speed or an acceleration. The degree of damage to the roller 4 is determined from the size.

ともに振動ピックアップで検出されるのである。However, in the above-mentioned non-disassembly inspection, the obtained discrimination result does not always coincide with the actual degree of damage of the roller 4, and the roller 4 is not actually damaged. In many cases, it is often determined that there is damage, or in fact, even a small damage is a large damage. According to the investigation by the present applicants, the main cause was rotation of the wheel set 5. That is, when the wheel shaft 5 is rotated to obtain the vibration from the roller 4, vibrations in the same frequency range as the roller 4 may be generated from the wheel 12 or the pinion gear 9 fitted thereto. Is detected by the vibration pickup together with the vibration from the rollers.

An object is to provide an outer ring rotating device for a bearing.
