Abstract
The utility model relates to the technical field of gear reducers, and discloses a combined sealing system of a three-ring gear reducer for a piling machine. The combined sealing system comprises an output shaft upper end sealing system and an output shaft lower end sealing system, wherein the output shaft upper end sealing system consists of a mechanical labyrinth combined sealing device and lubricating oil filled in gaps of a mechanical labyrinth, and the output shaft lower end sealing system consists of a lower shaft sleeve pressing plate (10), a combined sealing device, a lower shaft sleeve (14) and an inner covering framework sealing ring (15) which are connected onto a hollow shaft (19) and arrayed sequentially. The combined sealing system is capable of sealing a box for preventing lubricating oil inside the box from leaking outwardly and preventing cement paste outside the box from entering the box, and further capable of self-lubricating for prolonging the service life of the sealing ring. Therefore, the gear reducer is capable of piling for 3-4 myriameters without replacing internal bearings and the sealing ring, and the service lives of all bearings, an inner toothed ring plate, an outer toothed gear and the sealing ring inside the special three-ring gear reducer for the piling machine are prolonged greatly after combined sealing.
Description
Technical field
The utility model relates to the speed reducer technical field, relates in particular to a kind of machine three-ring gear reducer combination sealing system, and this system can seal the outside seepage of speed reducer internal lubrication oil and the outside cement slurry of speed reducer enters in the speed reducer casing.
Background technique
At present, the special-purpose three-ring gear reducer of known stake machine is to adopt traditional sealing means, can not sealing lubricating oil and cement slurry, during use, the output shaft upper end the outside cement slurry of speed reducer often occurs and enters casing in using rules, and all seal rings of output shaft upper end are in no deep-fried twisted dough sticks spare work.The outside seepage of lubricant oil in use often appears in the output shaft lower end, because the seal ring in the Lower shaft sleeve assembly process in the Lower shaft sleeve is stung bad by hollow shaft easily, the bad seal ring of stinging that has in the assembly process is found, the seal ring that has can not be found after being snapped badly, causes occurring in the working procedure seepage.Its problem is as follows:
1, Lower shaft sleeve endoporus and cylindrical in use often appear in the output shaft lower end all the seepage phenomenon, brings very big inconvenience to construction, and the outward appearance of speed reducer is very dirty, and uncontrollable to speed reducer internal lubrication oil quantity in the working procedure,
2, in using rules, often occur the outside cement slurry of speed reducer on the output shaft and enter the casing phenomenon, after cement slurry enters speed reducer, speed reducer internal lubrication oil is just impure, speed reducer working life is shortened in the wearing and tearing of the inner components such as internal tooth ring plate, external tooth gear, bearing and seal ring of acceleration-deceleration machine inside.
3, processed complex, difficulty of processing are big, the check difficulty is bigger, and assembling difficulty is also bigger, and is assembled to such an extent that the speed reducer sealability is also unreliable.
Summary of the invention
In order to overcome existing stake machine three-ring gear reducer, the output shaft lower end seepage phenomenon and output shaft upper end in use often occurs and the phenomenon that the outside cement slurry of speed reducer enters casing often occurs in using rules when proper functioning, the utility model provides a kind of machine three-ring gear reducer combination sealing system, the outside cement slurry of outside seepage of lubricant oil and casing enters casing in not only can seal case, but also can selflubricating, increase the working life of seal ring.
For achieving the above object, the utility model adopts following technological scheme:
A kind of machine three-ring gear reducer combination sealing system, comprise: output shaft upper end sealing system and output shaft lower end sealing system, described output shaft upper end sealing system is made of mechanical mazy type combination sealing arrangement and the lubricant oil that fills up slit in the mechanical labyrinth, described mechanical mazy type combination sealing arrangement is by being provided with rubber pad and O RunddichtringO between hollow shaft gland that is provided with on the hollow shaft and the hollow shaft; Be provided with rubber pad and O RunddichtringO between the Upper shaft sleeve of described hollow shaft cylindrical setting and the hollow shaft gland; Constitute labyrinth gap between gland that the Upper shaft sleeve below is provided with and the Upper shaft sleeve, labyrinth gap is filled up the lubricant oil of sealing cement slurry; Described output shaft lower end sealing system connects and composes by being connected Lower shaft sleeve pressing plate, combination sealing arrangement, Lower shaft sleeve and the Nei Bao backbone sealing ring arranged in regular turn on the hollow shaft, described combination sealing arrangement is arranged in regular turn by O RunddichtringO, Lower shaft sleeve dividing plate, O RunddichtringO and is constituted, and described Lower shaft sleeve pressing plate, O RunddichtringO, Lower shaft sleeve dividing plate, O RunddichtringO and Lower shaft sleeve are connected as a single entity by bolt.
A kind of machine three-ring gear reducer combination sealing system, described mechanical mazy type combination sealing arrangement is provided with the oil filler grease nipple of a lubricant oil.
Owing to adopt as above technological scheme, the utlity model has following superiority:
A kind of machine three-ring gear reducer combination sealing system, not only can seal case in the outside seepage of lubricant oil and the outside cement slurry of casing enter casing, but also can selflubricating, increase the working life of seal ring.Solve the problem that prior art exists, it is reliable to have sealing, life-span is long, and speed reducer piling 3-4 myriametre need not be changed internal bearings and seal ring, by improving the working life of inner all bearings of the special-purpose three-ring gear reducer of stake machine, internal tooth ring plate, external tooth gear, seal ring etc. behind the combination seal greatly.Its effect is as follows:
1, reduces difficulty of processing, because axle sleeve endoporus processing seal groove is not easy to control tolerance.
2, reduce to check difficulty,, and check that the result who comes out is also inaccurate because axle sleeve endoporus processing seal groove is not easy inspection.
3 reduce assembling difficulty, because the separately assembling of seal ring and other parts avoids seal ring to be snapped bad phenomenon.
4, the cement slurry of other equipment seepages can only drain to speed reducer in appearance in the using process, can not drain in the speed reducer casing.
5, speed reducer internal lubrication oil can outside again seepage.
