Abstract
The utility model discloses a lubrication structure of a decelerator. The decelerator comprises a casing, a driving shaft, and a driving shaft bearing. The lubrication structure is characterized in that the casing is provided with a spoon-shaped oil-collecting box; the oil-collecting box is disposed in parallel with the driving shaft, and an oil-scraping sheet is disposed at one side of the oil-collecting box adjacent to the shaft diameter of the driving shaft; an oil-guiding pipe is disposed in the casing; one end of the oil-guiding pipe is connected to the oil-collecting box, and the other end of the oil-guiding pipe is adjacent to the driving shaft bearing; one end of the oil-guiding pipe connected to the oil-collecting box is higher than the other end of the oil-guiding pipe, adjacent to the driving shaft bearing. The lubrication structure of a decelerator is advantageous in that the structure is simple and the installation is convenient; the function of forced lubrication is possessed; when the decelerator is running at a low speed, the driving shaft bearing can have complete lubrication and bearing damage due to insufficient lubrication can be prevented.
Description
Technical field
The utility model relates to a kind of retarder, is specifically related to a kind of lubricating structure of retarder.
Background technique
The retarder of pumping unit is main with two circular arc herringbone reducers in the prior art, and good lubricated gear and all bearings of can guaranteeing worked under kilter.At present, oil pump speed reducer adopts traditional splash lubrication mode, and the part of gearwheel is positioned at below the lubricant oil liquid level, and the lubricating oil splash that its running takes up lubricates other gears to other gears.Drive shaft bearing lubricated is to work the lubricant oil that splashes to case lid through gear band, and lubricant oil flows on the bearing along cover wall, flows in the casing through spill port again.When the driving shaft rotating speed of oil pump speed reducer hanged down, gear can't take up lubricant oil and be splashed on the cover wall, and drive shaft bearing can't be lubricated, and in use bearing is owing to can not get the lubricated damage that is easy to.
The model utility content
The purpose of the utility model is to overcome when having the retarder low-speed running now; Drive shaft bearing can not get sufficient lubrication; The deficiency that causes damage of bearings provides a kind of retarder lubricating structure, and this machine retarder lubricating structure can be good at satisfying the lubricated of drive shaft bearing under the low-speed running state.
For realizing above-mentioned purpose; The technological scheme of the utility model is the lubricating structure of a kind of retarder of design; Said retarder comprises casing, driving shaft, the drive shaft bearing of retarder, it is characterized in that, the oil box of spoonful shape is installed in said casing; The mounting point of said oil box is parallel to said driving shaft, and said oil box is provided with oil-scrapping sheet in the diameter of axle one side near said driving shaft; In said casing, be provided with oil guide pipe, an end of said oil guide pipe is connected with said oil box, and the other end of said oil guide pipe is near said drive shaft bearing; The end that said oil guide pipe is connected with said oil box is higher than the other end near drive shaft bearing.
Wherein, the quantity of said oil box has 2 at least.
Wherein, said oil box is installed in the said casing through screw, or is plugged in the casing through draw-in groove.
The advantage and the beneficial effect of the utility model are: the lubricating structure of this retarder has simple in structure, easy for installation; The pressure lubrication function is arranged; Can guarantee retarder when low-speed running, drive shaft bearing obtains sufficient lubrication, avoids causing damage of bearings because of lack of lubrication.
Description of drawings
Fig. 1 is the lubricating structure schematic representation of the utility model retarder;
Fig. 2 is the A-A sectional view of Fig. 1.
Among the figure: 1, oil-scrapping sheet; 2, oil box; 3, oil guide pipe; 4, drive shaft bearing; 5, driving shaft, 6, casing.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the embodiment of the utility model is further described.Following examples only are used for more clearly explaining the technological scheme of the utility model, and can not limit the protection domain of the utility model with this.
As depicted in figs. 1 and 2, the lubricating structure of a kind of retarder of the utility model comprises casing 6, driving shaft 5, the drive shaft bearing 4 of retarder, on the reduction case 6 parallel with driving shaft 5 oil box 2 is installed.Outwards extend in the two ends of oil box 2, an end wherein is fixedly connected with reduction case 6, and the other end is tilted upward slightly, and near driving shaft 5 diameter of axle places, promptly oil-scrapping sheet 1.One end of oil guide pipe 3 is connected with oil box 2; The other end is near drive shaft bearing 4, and oil guide pipe 3 outlets are positioned at the rolling element place of drive shaft bearing 4 lower ends.The end that oil guide pipe 3 is connected with oil box 2 is higher than the other end near drive shaft bearing 4.The quantity of oil box 2 is preferably 2.
The working procedure of the utility model on the oil pump speed reducer lubricating fitting is following;, gear lower when driving shaft 5 rotating speeds of oil pump speed reducer can't take up lubricant oil when splashing; The oil-scrapping sheet 1 that front end upwarps slightly scrapes the lubricant oil on the driving shaft 5, and the lubricant oil that scrapes is in oil-scrapping sheet 1 flows to oil box 2, and the oil in the oil box 2 passes through oil guide pipe 3 water conservancy diversion to drive shaft bearing 4; To drive shaft bearing 4, make it obtain good lubrication the lubricant oil forced feed.
The utility model applicability is strong, not only is confined to oil pump speed reducer, also can be used in other similar means lubricated.
The above only is the preferred implementation of the utility model; Should be understood that; For those skilled in the art; Under the prerequisite that does not break away from the utility model know-why, can also make some improvement and retouching, these improvement and retouching also should be regarded as the protection domain of the utility model.
