Description

Technical Field

[0001] The utility model relates to a piece of equipment machinery for rail transportation, in particular to a bearing rotating device. Background Art

[0002] During the press-fitting process of train wheel bearings, the bearing press machine pushes against the inner ring of the bearing until it is pressed into place. To prevent press-fit failure, where the bearing struggles to rotate or won't rotate at all, manual inspection was previously used during the process. This method involved manually rotating the bearing while pressing. This was time-consuming, labor-intensive, and unsafe, making it unsatisfactory. Consequently, a bearing rotation device was developed and installed on the bearing press machine. During the press-fitting process, the device rotates the bearing, allowing a human operator to observe whether the bearing is rotating. However, this bearing rotation device still required close human observation and was unsuitable for the demands of modern, mechanized, and automated production. Summary of the Invention

[0003] In order to solve the deficiencies in the prior art, the utility model provides a bearing rotating device, which has a scientific and reasonable structure and can mechanize and automatically realize the detection of the bearing press-fitting state.

[0005] The described runner assembly is provided with a runner under the rotating motor;

[0006] The detection wheel assembly is provided with a small slide in front of the slide, an elastic lifting mechanism is provided between the small slide and the slide, a detection wheel, a bearing and a bearing seat are provided under the small slide, and the rear axle of the detection wheel is connected to the sensor;

[0007] The lifting assembly is connected to the guide assembly by a guide movement force.

[0008] The rotating wheel and the detection wheel are both rubber-coated wheels.

[0009] The elastic lifting mechanism is a spring sleeved on the optical axis.

[0010] The guiding moving force is an oil cylinder or a gas cylinder.

[0029] The following describes embodiments of the present invention in conjunction with the accompanying drawings. It should be understood that the embodiments described herein are only used to illustrate and explain the present invention and are not used to limit the present invention.

[0030] like Figures 1 to 9 As shown, the utility model discloses a bearing rotating device, including a seat frame 1 and a slide plate 2, a rotating wheel assembly 3, a detection wheel assembly 4, and a lifting assembly 5; the sliding plate is mounted on the seat frame, and the rotating wheel assembly and the detection wheel assembly are mounted on the seat frame and the slide plate;

[0031] The rotating wheel assembly 3 is provided with a rotating wheel 32 under the rotating motor 31;

[0032] The detection wheel assembly 4 is provided with a small slide 41 in front of the slide, a lifting mechanism 42 is provided between the small slide and the slide, a detection wheel 43 and a bearing and a bearing seat 44 are provided under the small slide, and a sensor 45 is connected to the rear axle of the detection wheel;

[0033] The lifting assembly 5 is connected to the guide assembly 52 by the guide movement force 51.

[0034] The rotating wheel and the detecting wheel are both rubber-coated wheels, which are in flexible contact with the bearings to prevent damage to the bearings.

[0035] The elastic lifting mechanism is a spring 422 sleeved on the optical axis 421 .

[0036] The guiding moving force is an oil cylinder or a gas cylinder.

[0037] The guide assembly is a guide rail and guide groove pair.

[0038] The working process of this utility model is as follows:

[0039] like Figure 5-9 As shown, the utility model is installed on the large piston rod of the bearing press cylinder device, and moves forward and backward with the large piston rod. When the bearing is pressed, the utility model's rotating wheel and the detection wheel are lowered at the same time through the lifting assembly, and the detection wheel first contacts the bearing, and then the detection wheel is lowered to push the small slide plate to rise, and the rotating wheel contacts the bearing, and the rotating motor is started to drive the bearing to rotate. The detection wheel rotates with the bearing, and its detection signal is transmitted to the industrial computer for display through the sensor connected to the detection wheel. The success or failure of the bearing press can be seen intuitively, and there is no need for manual observation, which saves time and effort and ensures safety. A lifting assembly is provided behind the slide plate, which drives the rotating wheel assembly and the detection wheel assembly to move up and down, and can avoid interference with the wheel pair entering the bearing press.
