Abstract
The utility model relates to a kind of anti-oil-leakage retarding machines, input shaft or output shaft are supported in cabinet through self-aligning roller bearing, disc, transparent cover, outside framework oil seal and envelope pressing plate are successively socketed on the input shaft or output shaft shaft part of self-aligning roller bearing outer end, disc inner end pushes against self-aligning roller bearing outer end, disc outer end is connected on shaft part through snap ring and positions, transparent cover inner end pushes against self-aligning roller bearing outer end, and outside framework oil seal, which is set between end cap and shaft part and is sealed pressing plate, is bolted transparent cover compression.Its is compact-sized, can effectively prevent oil leakage, takes into account speed reducer performance and used life.
Description
Technical field
The utility model relates to a kind of speed reducer, specifically a kind of anti-oil-leakage retarding machine.
Background technique
Traditional speed reducer is typically easy to that oil leakage occurs on shaft, and existing using sealing ring, oil enveloping structure
Although can enhance sealing performance, since lubricating oil is always behind sealing structure top, the long-time service of speed reducer, there are still few
There is leakage hidden danger after amount leakage and sealing element senile abrasion.
Summary of the invention
The utility model provides a kind of compact-sized, can effectively prevent oil leakage, takes into account the leakproof of service life
Oily speed reducer.
The technical solution adopted in the utility model is: a kind of anti-oil-leakage retarding machine, including cabinet, input shaft and output shaft,
It is characterized by: the input shaft or output shaft are supported in cabinet through self-aligning roller bearing, self-aligning roller bearing outer end it is defeated
Enter successively to be socketed with disc, transparent cover, outside framework oil seal and envelope pressing plate on axis or output shaft shaft part, disc inner end pushes against aligning rolling
Sub- bearing outer end, disc outer end are connected on shaft part through snap ring and position, and transparent cover inner end pushes against self-aligning roller bearing outer end, skeleton
Oil sealing, which is set between end cap and shaft part and is sealed pressing plate, is bolted transparent cover compression.
Further, disc is equipped on the self-aligning roller bearing inner end and input shaft or output shaft shaft part between the shaft shoulder,
Or disc is equipped between self-aligning roller bearing inner end and input shaft or output shaft shaft part gear.
Still further, the disc includes ring body and the fin around ring body outer wall, section for triangle outwardly.
The utility model is respectively provided at the inside and outside end of self-aligning roller bearing that input or the installation of output shaft are used to support and gets rid of oil
Ring is further dropped in conjunction with outer end setting outside framework oil seal by envelope pressing plate encapsulation crimping sealing transparent cover and shaft part, compact overall structure
The low lubricating oil leaked out by self-aligning roller bearing, and the lubricating oil of leakage is thrown back, then be aided with outside framework oil seal and finally seal, energy
It is effectively prevent oil leakage, extend the service life of sealing structure and improves the service performance of speed reducer.
Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model；
Fig. 2 is enlarged drawing at A in Fig. 1；
Fig. 3 is enlarged drawing at B in Fig. 1.
In figure: cabinet 1, input shaft 2, output shaft 3, self-aligning roller bearing 4, outer disc 5, snap ring 6, transparent cover 7, skeleton oil
Envelope 8, envelope pressing plate 9, interior disc 10.
Specific embodiment
It is described further below in conjunction with drawings and examples.
Shown in Fig. 1-3: a kind of anti-oil-leakage retarding machine, including cabinet 1, input shaft 2, output shaft 3, as in Fig. 2 on input shaft 2
It is supported in cabinet through self-aligning roller bearing 4, self-aligning roller bearing inner end is located on the shaft shoulder of input shaft, self-aligning roller bearing
Outer disc 5, snap ring 6, transparent cover 7, outside framework oil seal 8 and envelope pressing plate 9 are socketed on the input shaft of outer end, outer 5 inner end of disc is supported
Tight self-aligning roller bearing outer end, the outer end of outer disc 5 is connected on axis through snap ring 6 to be positioned, and the inner end of transparent cover 7 pushes against aligning rolling
Sub- bearing outer end, transparent cover 7 are equipped with annular groove outwardly, set outside framework oil seal 8 in annular groove, the inner circle of outside framework oil seal 8 is socketed in input
On axis, outside framework oil seal 8 is bolted transparent cover 7 through envelope pressing plate 9 and is crimped in annular groove；In such as Fig. 3, structure on output shaft 3
It is identical as on input shaft, interior disc is equipped between the self-aligning roller bearing inner end on output shaft and output shaft gear end face
10。
