Abstract
The utility model relates to an oil-tight speed reducer, comprising an output shaft, a shaft cap, a bearing, a bearing cap, a drive bevel gear, a driven bevel gear and a flange. The utility model is characterized in that the bearing on the front end of the drive bevel gear is provided with an oil insulating ring, the inner end surface of the shaft cap and the bearing cap is provided with a pressure reduction groove; the end surface of the connection of the shaft cap and the flange is provided with a zigzag flanged lip. The utility model has the advantage of effectively preventing the lubricating oil in the speed reducer from flowing out of the speed reducer along the output shaft.
Description
One, technical field
The utility model relates to a kind of speed reducer, relates in particular to a kind of anti-leakage of oil speed reducer.
Two, background technique
Present speed reducer mainly is made up of output shaft, shaft-cup, bearing cap, bearing, drive bevel gear, driven wheel of differential and flange; Shaft-cup, bearing cap are installed in the outside of output shaft; Owing in speed reducer, need to add lubricant oil to drive bevel gear, driven wheel of differential and bearing are lubricated, it can be run well, but lubricant oil flows on the output shaft from the front end of drive bevel gear and from the gap between flange and the shaft-cup easily, again along output shaft and shaft-cup, gap between the bearing cap flows to outside the speed reducer, make the lubricant oil in the speed reducer constantly reduce, the final time, the drive bevel gear that makes like this, driven wheel of differential and bearing are easy to and will can't work because of wearing and tearing, flow of lubricant also pollutes and has destroyed speed reducer environment on every side to the outside of speed reducer simultaneously.
Three, summary of the invention
At above-mentioned shortcoming, the purpose of this utility model is to provide a kind of interior lubricant oil of speed reducer that can make can not flow to the outer anti-leakage of oil speed reducer of speed reducer.
Technology contents of the present utility model is that a kind of anti-leakage of oil speed reducer comprises output shaft, shaft-cup, bearing, bearing cap, drive bevel gear, driven wheel of differential and flange; It is characterized by an oil removal circle is housed on the bearing of drive bevel gear front end, on the interior edge face of shaft-cup and bearing cap, have the decompression groove; On the end face that is connected of shaft-cup and flange, the zigzag fashion flange is arranged.
By on the bearing of drive bevel gear front end, loading onto the oil removal circle, can prevent that lubricant oil from flowing on the output shaft from the front end of drive bevel gear; Zigzag fashion flange on the end face of shaft-cup and flange connection can prevent that lubricant oil from flowing on the output shaft from the gap between flange and the shaft-cup; When still having less amount of lubrication oil to leak on the output shaft, unable again outside output shaft flows to speed reducer after the decompression groove on the interior edge face of shaft-cup and bearing cap can make lubricant oil fall into the decompression groove.
The advantage that the utility model is compared with prior art had is:
1, can prevent effectively that the lubricant oil in the speed reducer from flowing out speed reducer along output shaft.
2,, the working environment of speed reducer is not polluted destruction owing to do not have flow of lubricant outside speed reducer.
Four, description of drawings
Fig. 1 is a structural representation of the present utility model.
Five, specific embodiment
As shown in Figure 1, a kind of anti-leakage of oil speed reducer comprises output shaft 1, shaft-cup 2, bearing 3, bearing cap 4, drive bevel gear 5, driven wheel of differential 6 and flange 7; Shaft-cup 2 and bearing cap 4 are installed in the outside of output shaft 1; One oil removal circle 8 is housed on the bearing 3 of drive bevel gear 5 front ends, on the interior edge face of shaft-cup 2 and bearing cap 4, has decompression groove 9; On the surface of contact of shaft-cup 2 and flange 7, zigzag fashion flange 10 is arranged.
