Abstract
The utility model provides an oil leakage preventing device for a vertical high-pressure motor oil chamber, which comprises an oil chamber filled with machine oil. The upper end and the lower end of the oil chamber are respectively provided with an oil chamber cover plate and an upper end cover. The oil leakage preventing device for the vertical high-pressure motor oil chamber is characterized in that: the inner wall of the oil chamber is provided with a decompression pipe which extends into the oil chamber at a position that is next to the oil chamber cover plate; and the wall of the oil chamber is provided with a through hole which is communicated with the decompression pipe. According to the oil leakage preventing device for the vertical high-pressure motor oil chamber, the inside surface of the oil chamber is provided with the decompression pipe at the position that is next to the cover plate; and furthermore a through hole is arranged at a corresponding position for equalizing the pressures inside the oil chamber and outside the oil chamber, thereby settling a problem of oil leakage at the oil chamber cover plate of the prior vertical high-pressure motor.
Description
Technical field
The utility model relates to a kind of vertical high-voltage motor grease chamber anti-oil leakage device, belongs to vertical high-voltage motor grease chamber sealing device.
Background technology
Bearing larger axis in the vertical high-voltage motor of power, upper bearing (metal) generally adopts self-aligning thrust roller bearing, and it has automatic aligning ability, adopts 32# engine oil lubrication, and grease chamber seals.Existing structure is between upper end cover and rotating shaft, to have welded the oily support of gear, has solved the Leakage of motor internal.But because grease chamber seals, after motor rotation, can form pressure reduction in inside, grease chamber, cause internal oil pressure to be greater than atmospheric pressure, oil can overflow from cover plate faying face.
Summary of the invention
The purpose of this utility model is to solve existing vertical high-voltage motor oil chamber cover board place Leakage.
In order to achieve the above object, the technical solution of the utility model has been to provide a kind of vertical high-voltage motor grease chamber anti-oil leakage device, comprise the grease chamber that fills machinery oil, the two ends up and down of grease chamber are respectively equipped with oil chamber cover board and upper end cover, it is characterized in that: be provided with the relief pipe stretching in grease chamber at grease chamber's inwall near oil chamber cover board position, on the wall of grease chamber, have the through hole communicating with relief pipe.
The utility model has welded a relief pipe at grease chamber's medial surface near cover plate place, and makes a call to a through hole in corresponding position, makes grease chamber's inside and outside differential pressure consistent, has solved existing vertical high-voltage motor oil chamber cover board place Leakage.
Accompanying drawing explanation
The structural representation of a kind of vertical high-voltage motor grease chamber anti-oil leakage device that Fig. 1 provides for the utility model.
Embodiment
For the utility model is become apparent, hereby with preferred embodiment, and coordinate accompanying drawing to be described in detail below.
The utility model provides a kind of vertical high-voltage motor grease chamber anti-oil leakage device, comprises the grease chamber 6 that fills machinery oil 4, and machinery oil 4 is 32# engine oil lubrication, and the two ends up and down of grease chamber 6 are respectively equipped with oil chamber cover board 3 and upper end cover 7.Machine shaft 1 is located on upper end cover 7, has self-aligning thrust roller bearing 2 at machine shaft 1 overcoat.The utility model is provided with the relief pipe 5 stretching in grease chamber 6 near oil chamber cover board 3 positions at grease chamber's 6 inwalls, have the through hole communicating with relief pipe 5 on the wall of grease chamber 6, makes grease chamber's inside and outside differential pressure consistent, has solved grease chamber's Leakage.
