に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention is for measuring a gap of a bearing of a drive gear of a drive wheel shaft of a railway vehicle or the like or a gap of a bearing of a pinion meshing with the drive gear. The present invention relates to a drive wheel shaft bearing clearance measuring device.

ーの軸受の隙間は高精度をもって測定され、該測定にも
とづいて精密に調整されなければならない。Among the bearings of each part of the drive wheel axle of a railway vehicle, especially the bearing of the drive gear expands due to the heat generated while the vehicle is running, so to absorb such expansion, the outer race, rollers,
It is necessary to provide a clearance in the bearing configured with the inner race. However, if this gap is too large, wear is promoted due to impact due to so-called rattling during traveling, and the life of the bearing is shortened. Therefore, the clearance of the bearing of the drive gear of the drive wheel shaft must be measured with high accuracy and must be precisely adjusted based on the measurement.

該（δ１）は軸受の隙間（δ）に比例することから上記
測定によって軸受（４）の隙間（δ）を求める。The same applies to the bearing of the pinion that meshes with the drive gear. FIG. 2 is a structural explanatory view of an example of a drive wheel shaft, in which FIG. 2 (a) is a transverse sectional view thereof, and FIG. 2 (b) is a partially enlarged sectional view of a bearing of a drive gear.
The wheel (2) is searched for on the axle (1) and the axle (1), the drive gear (3) and the inner races (42) (42) of the bearings (4) (4) are integrally connected, Bearing (4)
The outer races (41) (41) of (4) and the gear box (5) are integrally connected, and a plurality of conical rollers (43) (4)
It is rotatably attached to the inner races (42) and (42) with a predetermined gap (δ) through 3). The pinion (6) meshes with the drive gear (3), and the pinion (6), the pinion shaft (61) and the inner race (72) of the bearing (7) of the pinion are integrally connected. The outer race (71) of the bearing (7) of the pinion is fixed to the gear box (5) and is rotated through the rollers (73) (73) to the inner races (72) (72) with a predetermined clearance as described above. It is freely circulated. In order to measure the clearance (δ) of the bearing (4) of the drive gear (3) of the drive wheel axle having the above-mentioned structure, the gear box (5) of the drive wheel axle held horizontally is used for the axle. By moving it in the axial direction of (1), the displacement of the gearbox (5) having the outer race (41) fixed thereto with respect to the axle (1) having the inner race (42) fixed thereto is measured. The displacement is the outer race (4
It corresponds to the displacement (δ1) of the inner race (42) in 1),
Since (δ1) is proportional to the clearance (δ) of the bearing, the clearance (δ) of the bearing (4) is obtained by the above measurement.

間を求める。Alternatively, the gearbox (5) of the drive wheel shaft held vertically
The displacement of the gear box (5) when the suspension is suspended by a crane or the like is compared with the displacement when the suspension is not suspended. By measuring the displacement, the clearance (δ) of the bearing (4) can be obtained based on the same principle as described above. Also in the case of measuring the clearance of the bearing (7) of the pinion (6), the measurement is performed in substantially the same manner as above. That is, the drive wheel shaft is held horizontally or vertically, the gear box (5) is fixedly held, and the pinion shaft (61) is moved to move the inner race (72).
The clearance of the pinion bearing (7) is obtained based on the same principle as above by measuring the displacement of the pinion shaft (61) fixed to the gearbox (5) fixed to the outer race (71). .

直に保持するため測定作業は極めて危険であり、また低
能率であるという問題があった。However, when measuring the clearance between the bearings (4) while holding the wheel (2) horizontally, the moving direction of the axial center of the inner race (42) and the axial center of the outer race (41) are parallel to each other. If not, a so-called "twisting" or "squealing" phenomenon occurs, and accurate displacement cannot be measured. Also, when measuring the bearing gap with the drive wheel shaft held vertically, the phenomenon referred to as the above "twisting" or "tightening" can be avoided, but the measurement work is performed because the drive wheel shaft is held vertically. Was extremely dangerous and had a problem of low efficiency.
