Problems solved by technology

[0004] Although the above solution solves the deficiencies of the prior art to a certain extent, the oil retaining effect is not good enough, and the oil is still easy to leak. In addition, the lubricating oil is not evenly distributed on the bearing surface, which is not conducive to lubrication, and the overall design is not reasonable enough.

Embodiment

[0022] Such as Figure 1-2 As shown, the water guide bearing oil retaining mechanism includes a cylindrical body 4 arranged at the main shaft 2 with the shaft collar 1 and located in the annular space 3 formed between the main shaft 2 and the shaft collar 1. The main shaft 2 is fixed On the main shaft seat 9 and between the main shaft 2 and the main shaft seat 9, there is a bearing 6 sleeved outside the collar 1. The bearing 6 is rotatably connected with the main shaft 2. The feature is that the body 4 There is a pressure forming structure 5 which can form a positive pressure when the main shaft 2 rotates so as to prevent the loss of lubricating oil. The pressure forming structure 5 forms a positive pressure on the main shaft 2, that is, when the main shaft 2 rotates, since the main body 4 is provided with a helical groove 7, the main shaft 2 and the helical groove 7 rotate relatively, so that the gap between the main shaft 2 and the main body 4 The gap in the gap forms press...

Abstract

The invention belongs to the technical field of bearing parts, and particularly relates to an oil stopping mechanism of a turbine guide bearing. The oil stopping mechanism of the turbine guide bearing comprises a cylindrical body which is arranged at a main shaft provided with a shaft collar and located in an annular space formed between the main shaft and the shaft collar, the main shaft is fixed on a main shaft seat, the bearing arranged on the shaft collar in a sleeving mode is arranged between the main shaft and the main shaft seat, and the bearing is rotatably connected with the main shaft. The oil stopping mechanism of the turbine guide bearing is characterized in that the body is provided with a pressure forming structure which can form positive pressure to prevent lubricating oil from running off when the main shaft is rotated. The oil stopping mechanism of the turbine guide bearing has the advantages that the pressure forming structure can form the positive pressure on the main shaft, therefore, the lubricating oil is prevented from leaking, the oil stopping effect is good, the overall design is reasonable, and the structure is simple; the lubricating oil can be contained in a spiral groove in the rotating process of the main shaft, therefore, the lubricating oil leakage is reduced, and the oil stopping effect is good; the oil stopping mechanism is beneficial for the lubricating oil to be evenly distributed on the surface of the main shaft, and lubricating is facilitated.

Description

technical field [0001] The invention belongs to the technical field of bearing components, and in particular relates to an oil retaining mechanism of a water guiding bearing. Background technique [0002] The water guide tile can withstand the radial force of the main shaft of the water turbine, and is a bearing that can keep the main shaft in the center position. Widely used in hydroelectric generator sets, large water pumps, cement mills, ball mill bearings, ship machinery and other fields. The water guide pad bearing oil retaining cylinder in the prior art can block the fluctuating oil when the oil in the oil tank fluctuates, preventing the oil from leaking through the oil retaining cylinder. However, the oil retaining effect is not good enough, and the oil is still easy to leak. In addition, the lubricating oil is not evenly distributed on the bearing surface, which is not conducive to lubrication. [0003] In order to improve the existing technology, people have carri...
