Abstract
The utility model relates to a kind of double oil seals to arrange transparent cover, including two outside framework oil seals being set between speed reducer transparent cover inner wall and shaft, two outside framework oil seals are arranged in parallel and there are the gaps for forming outer oil seal lubricating cavity between the two, transparent cover top is equipped with oil inlet passage, the collar extension of oil inlet passage connects lubricating cup through atomizer, the internal orifice of oil inlet passage is connected to outer oil seal lubricating cavity, and transparent cover lower part is equipped with drainback passage, and drainback passage is connected to outer oil seal lubricating cavity and decelerating chassis intracoelomic cavity；The corresponding transparent cover inner wall of outer oil seal lubricating cavity is equipped with the baffle ring plate with the discontiguous multi-turn baffle ring plate of shaft or a circle helical structure.Its structure is simple, compact, and energy effectively lubricating double oil seal avoids influencing service performance in external oil sealing excessive wear.
Description
Technical field
The utility model relates to speed reducers, and specifically speed reducer double oil seal arranges transparent cover.
Background technique
Traditional transparent cover wears to pick out and generallys use two or more oil sealings on axis and carry out placing the leakage of internal lubrication oil, but due to the
The sealing of one of oil sealing, basic non lubricant oil at second oil sealing, is chronically at dry condition, leakage is easily caused after abrasion.
Summary of the invention
It is simple, compact that the utility model provides a kind of structure, can effectively lubricating double oil seal, avoid in external oil sealing
The double oil seal that excessive wear influences service performance arranges transparent cover.
The technical solution adopted in the utility model is: a kind of double oil seal arrangement transparent cover, including is set in speed reducer transparent cover
Two outside framework oil seals between wall and shaft, it is characterised in that: two outside framework oil seals be arranged in parallel and between the two there are
The gap of outer oil seal lubricating cavity is formed, transparent cover top is equipped with oil inlet passage, and the collar extension of oil inlet passage connects lubricating cup through atomizer, into
The internal orifice in oily channel is connected to outer oil seal lubricating cavity, and transparent cover lower part is equipped with drainback passage, drainback passage be connected to outer oil seal lubricating cavity and
Decelerating chassis intracoelomic cavity；The corresponding transparent cover inner wall of the outer oil seal lubricating cavity be equipped with the discontiguous multi-turn baffle ring plate of shaft or
The baffle ring plate of one circle helical structure.
The utility model between two outside framework oil seals there are outer oil seal lubricating cavity, by transparent cover top oil inlet passage, by
Lubricating cup supplies outer oil seal lubricant reservoir through atomizer oil spout, and lubricating oil is in outer oil seal lubricant reservoir in external second
Outside framework oil seal is limited and effective feed lubrication, avoids oil leak caused by the excessive wear being used for a long time, outer oil seal lubrication
Intracavitary lubricating oil returns to decelerating chassis intracoelomic cavity by drainback passage；On the corresponding transparent cover inner wall of outer oil seal lubricating oil be equipped with
The baffle ring plate of the discontiguous multi-turn baffle ring plate of shaft or a circle helical structure, it is stagnant in outer oil seal lubricating cavity to extend lubricating oil
The time is stayed, lubricating cup fuel delivery is reduced and takes into account lubricant effect.
Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model.
In figure: transparent cover 1, shaft 2, the first outside framework oil seal 3, the second outside framework oil seal 4, outer oil seal lubricating cavity 5, baffle ring plate 6, into
Oily channel 7, atomizer 8, lubricating cup 9, drainback passage 10.
Specific embodiment
It is described further below in conjunction with drawings and examples.
Shown in Fig. 1, a kind of double oil seal arrangement transparent cover, including transparent cover 1, the first outside framework oil seal 3, the second outside framework oil seal 4, outer oil
Seal lubricating cavity 5, baffle ring plate 6, oil inlet passage 7, atomizer 8, lubricating cup 9, drainback passage 10.First and second outside framework oil seal 3,4 is by introversion
It is arranged in parallel between 1 inner wall of transparent cover of speed reducer and shaft 2 outside and between the two there are the gap for forming outer oil seal lubricating cavity 5,
1 top of transparent cover is equipped with oil inlet passage 7, and the collar extension of oil inlet passage 7 connects lubricating cup 9 through atomizer 8, and the internal orifice connection of oil inlet passage is outer
Oil sealing lubricating cavity, transparent cover lower part are equipped with drainback passage 10, and drainback passage is connected to outer oil seal lubricating cavity and decelerating chassis intracoelomic cavity；Institute
It states the corresponding transparent cover inner wall of outer oil seal lubricating cavity 5 and is equipped with the gear for enclosing helical structure with the discontiguous multi-turn baffle ring plate of shaft or one
Ring flat-plate 6.
