Embodiment Construction

[0021] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific implementation manners of the present invention will now be described in detail with reference to the accompanying drawings.

[0022] like figure 1 shown and combined with figure 2 . The oil baffle in this embodiment includes an oil baffle ring 3 sleeved on the rotating shaft 7, and an inner oil baffle plate 5 fitted on the outer periphery of the rotating shaft 7, and the inner oil baffle plate 5 is fixedly connected to the inner side of the oil baffle ring 3 , A gap is formed between the inner oil baffle 5 and the rotating shaft 7, the inner oil baffle 5 is used to block the oil attached to the rotating shaft 7 on the oil inlet path, and make the oil enter the oil baffle ring 3 below through the gap. The interval of the gap is L, 0.4≤L≤0.6 mm.

[0023] The oil retainer also includes an outer ring 1 and an inner ring 2. The inner side of th...

Abstract

The invention discloses an oil catch which comprises an oil catch ring (3) arranged on a rotating shaft (7) in a sleeving mode and an inner oil baffle plate (5) sleeving the periphery of the rotating shaft (7). The inner oil baffle plate (5) is fixedly connected to the inner side of the oil catch ring (3), a gap is formed between the oil baffle plate (5) and the rotating shaft (7), and the inner oil baffle plate (5) is used for blocking oil attached to the rotating shaft (7) on an oil inlet path and enabling the oil to enter the position below the oil catch ring (3) through the gap. The oil catch has the advantages that due to the inner oil baffle plate fixedly connected to the inner side of the oil catch ring, the intercepting ability is improved, namely oil attached to the rotating shaft is firstly blocked by the inner oil baffle plate and then enters the gap, and the sealing effect is good.

Description

technical field [0001] The invention relates to an oil sealing device, and more specifically, relates to an oil baffle installed at the rotating shaft of a generator for oil sealing and preventing the oil attached to the rotating shaft from being thrown out. Background technique [0002] Generators generally include a rotating shaft, but during the operation of the generator, with the rotation of the rotating shaft, the oil (such as lubricating oil) attached to the rotating shaft is easily thrown from the inside of the generator to the outside of the generator, which is not only harmful to the operation of the generator itself , and the oil thrown outside the generator is also likely to pollute other equipment, causing serious pollution to other equipment. In some cases, the oil thrown outside the generator will also cause problems such as short circuits of other equipment. In view of the above problems, the solution in the prior art is generally to insert an oil stopper on ...
