Description

Technical Field

[0001] This utility model relates to equipment machinery for rail transit, specifically to a bearing press machine's shaft support device. Background Technology

[0002] Existing bearing press-fitting machines typically use a center to lift the axle during the bearing press-fitting process. The deformation of the main hydraulic cylinder piston rod due to the weight of the wheelset affects the coaxiality of the two main hydraulic cylinder piston rods. To prevent this, a practical solution must be found. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this utility model provides a bearing press-fitting device with a simple structure, economic efficiency, and practicality. It reduces the deformation of the main cylinder piston rod caused by the weight of the wheelset and improves the coaxiality of the two main cylinder piston rods.

[0004] To achieve the above objectives, the technical solution of this utility model is a bearing press machine with a shaft support device, comprising a bearing press machine main unit, characterized in that: the shaft support device is disposed on the base of the bearing press machine main unit, and the shaft support device is one or two; the shaft support device is a shaft support cylinder, and a nylon pad is mounted on the top of the piston rod of the shaft support cylinder.

[0005] The nylon pads are available in different sizes.

[0006] The beneficial effects of this utility model are that it has a simple structure, is economical and practical. When the axle is held by the top, this device can support the axle, reduce the deformation of the piston rod of the main cylinder caused by the weight of the wheelset, and improve the coaxiality of the piston rods of the two main cylinders.

[0011] 2 rounds; 3 bearings. Detailed Implementation

[0012] The embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0013] like Figures 1 to 5 As shown, this utility model discloses a bearing press machine with a shaft support device 100, including a bearing press machine main unit 1, the shaft support device being disposed on the base 11 of the bearing press machine main unit, and the shaft support device 12 being one or two; the shaft support device is a shaft support cylinder, and a nylon pad 13 is mounted on the top of the piston rod of the shaft support cylinder.

[0014] The nylon pads are interchangeable in size to accommodate different axle diameters.

[0015] The working process of this wheelset is illustrated below: like Figure 3 As shown, the wheelset enters the bearing press-fitting machine center; like Figure 4 As shown, the small piston rod of the press-fit cylinder extends, the tip inserts into the tip hole of the axle to lift the axle, and the piston rod of the axle support device rises to support the axle; like Figure 5 As shown, the bearing press-fitting is completed, the piston rod of the bearing support device descends and resets, awaiting the next operation.

[0016] The above description is merely one embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
