Embodiment Construction

[0009] The present invention will be further described below in conjunction with the accompanying drawings: as shown in Figure 1, an air-cooled anhydrous thin oil lubricated cylindrical bearing structure with a shaft collar, which includes an upper oil tank 1, a bearing cover 3, an oil passing plate 4, a bearing body 6, a return Oil pipe 5, support cover 9, oil retaining cylinder 8 and signal monitoring device, bearing body 6 is a bearing body poured with babbitt alloy tiles. The lower oil tank is composed of the top cover 10, the seal 2, the bearing body 6, the pressure plate 7, the oil retaining cylinder 8, the support cover 9 and the corresponding connectors, through the external air cooling of the top cover and the formation between the bottom of the top cover and the runner The seal between the upper crown of the runner and the top cover in the annular cavity cools the top cover, thereby reducing the oil temperature. Some cooling fins are arranged on the top cover as part...

Abstract

A bearing of diluted oil lubrication barrel type with air cooling water free shaft collar consists of oil box, bearing cover, oil passing plate, bearing body, oil returning tube, support cover, oil blocking barrel and signal monitoring unit. It is featured as making said bearing be free of cooler for simplifying structure of said bearing and of providing great convenience on erection and maintenance of said bearing.

Description

[0001] Field [0002] The invention relates to a water turbine bearing device, in particular to an air-cooled thin oil lubricated cylindrical bearing structure without water collar. Background technique [0003] At present, the structural design of the hydraulic turbine bearing is relatively complicated, and the traditional structure of the hydraulic turbine bearing is equipped with a cooler, which is not conducive to installation and maintenance. The oil mist splashes in the oil circulation system, and the temperature is high during operation, which poses a safety hazard. Contents of the invention [0004] The purpose of the present invention is to overcome the disadvantages of the prior art and provide an air-cooled waterless thin oil lubricated cylindrical bearing structure with a shaft collar that does not need a cooler. The structure is simple, the oil circulation system is reliable, and the temperature is low during operation. [0005] The object of the present invent...
