Embodiment 2

[0036] Embodiment two: if Figure 5 As shown, only cylindrical roller bearings are used for the vibrating bearing and supporting bearing in this embodiment, and this embodiment is suitable for the case where the vibrating shaft component only bears radial force. All the other structures are the same as in Embodiment 1.

Embodiment 3

[0037] Embodiment 3: The four-point angular contact ball bearings and cylindrical roller bearings used together in Embodiment 1 are replaced by tapered roller bearings used in pairs. This embodiment can also carry axial force and radial force at the same time. force. All the other structures are the same as in Embodiment 1.

[0038] A method for cooling the vibrating part of a tamping device, which is implemented by any preferred solution contained in the above-mentioned embodiments, and the specific solution is as follows: a cooling device is arranged on the outer periphery of the high-temperature part of the vibrating shaft part of the tamping device, and the cooling device It at least includes a cooling channel, a cooling inlet, and a cooling outlet. The coolant is injected from the cooling inlet, and the coolant flows through the cooling channel and flows out from the cooling outlet, thereby taking away the heat of the high-temperature part and realizing the cooling of the...

Abstract

The invention relates to a tamping device vibration component with a cooling device. The tamping device vibration component comprises an eccentric vibration shaft (1), a vibration bearing and a vibration bearing sleeve; the inner side of the vibration bearing is connected with the eccentric vibration shaft (1), the outer side of the vibration bearing is connected with the vibration bearing sleeve,and the outer side of the vibration bearing sleeve is connected with the cooling device. The tamping device vibration component with the cooling device is adopted and used for a tamping device, effective cooling of the vibration component can be achieved, high-frequency operation of the tamping device can be achieved, the service life of the tamping device is further prolonged, and the engineering application value is high. The invention further provides a cooling method of the tamping device vibration component; the cooling device is arranged on the periphery of the high-temperature part ofthe vibrating shaft part of the tamping device, a cooling agent is injected from a cooling inlet, flows through a cooling channel and flows out from the cooling outlet, and thus heat of the high-temperature part is taken away, and cooling of the high-temperature part is achieved.

Description

technical field [0001] The invention relates to the technical field of railway maintenance machinery and equipment, in particular to a vibrating part of a tamping device including a cooling device and a corresponding cooling method. Background technique [0002] Tamping operation is one of the main tasks of ballasted railway track bed maintenance, which can effectively improve the stability of the track bed and ensure the safety of trains. At present, in the railway maintenance machinery industry, the widely used tamping devices all adopt the mechanical eccentric excitation method, and use the rotation of the eccentric shaft to generate vibration. The structure of the eccentric shaft part includes rolling bearings, which are lubricated with grease. Usually, the working temperature of the bearing at the eccentric part is about 120°C, which is close to the service limit temperature of ordinary grease. As a result, the temperature of the bearing rises, exceeding the service te...
