Description
Technical field
The present invention relates to transmission device technical fields, more particularly to the waterproof knot at a kind of output shaft of speed reducer
Structure and a kind of speed reducer.
Background technique
Speed reducer, also referred to as reduction gearbox or retarder are a kind of common transmission devices.The output end of speed reducer according to
Requirement can be designed in the lower section, top and side of the cabinet of speed reducer.The output end of speed reducer is arranged in the side of cabinet
The output shaft of Fang Shi, speed reducer are usually arranged horizontally.When the output end of speed reducer is arranged in the below or above of cabinet, slow down
The output shaft of machine is usually vertical arrangement.End cap would generally be arranged in the position that output shaft passes through cabinet, and output shaft makes across end cap
Output end exposes to end cap, and end cap can be used to compress bearing, oil sealing can generally be arranged at the inner wall of end cap, to prevent in cabinet
Cooperation place of the lubricating oil between end cap and output shaft leak out.
Speed reducer above cabinet is located at for output end, under general operating condition, the structures such as end cap, output shaft and oil sealing are complete
It can satisfy requirement entirely.But under the operating condition for thering is water to fall, such as when rainwater or cooling water fall in the top of speed reducer,
Water is easy for cooperation place between end cap and output shaft and enters in the cabinet of speed reducer, although usually end cap and output shaft it
Between be provided with oil sealing, but oil sealing can not stop the flowing of water completely, penetrated into the cabinet of speed reducer so still having water, from
And lead to bearing, gear, shaft and cabinet wall etc. and corrode, influence the normal use of speed reducer, reduce lubricant effect and
Service life etc..
Such as in the Rolling Production workshop of seamless steel pipe, the speed reducer of seamless steel pipe main mill is located at rolling seamless steel pipe
Underface needs to be rinsed seamless steel pipe with water during the rolling process, so having many water falls on underlying subtract
On fast machine.The part for being exposed to outside of the cabinet of speed reducer and other driving members can be carried out by smearing the methods of underwater paint
Waterproof, but do not prevent but water from entering the structure of cabinet from end cap and between output shaft in the prior art, water is easy to seep
Enter in the cabinet of speed reducer, causes bearing, gear, shaft and cabinet wall etc. very serious by the corrosion condition of water, make for a long time
Safety accident occurs with the structural rigidity decline for resulting even in cabinet and its inside.
Summary of the invention
The present invention is to overcome the deficiencies in the prior art described above, and provides the waterproof construction at a kind of output shaft of speed reducer
