Abstract
The utility model relates to a lubricating device for a pumping unit decelerator, which overcomes the shortcoming that when a current pumping unit decelerator is operated in low speed, a driving shaft bearing can not get enough lubrication, which causes damage to the bearing. The utility model comprises a gearbox body (6), a driving shaft (5), a driving shaft bearing (4), an oil-collecting box (2) which is installed on the gearbox body (6) parallel to the driving shaft (5), and an oil-scraping sheet (1) on the oil-collecting box (2) close to the axial diameter of the driving axle (5). One end of an oil pipeline (3) is connected with the oil-collecting box (2) and the other end is close to the driving shaft bearing (4). The utility model has the advantages of simple structure, convenient installation and compulsory lubricating function, and can guarantee that the driving shaft bearing gets enough lubrication when the decelerator is operated in low speed, and avoids damage to the bearing which is caused by lubrication deficiency.
Description
Affiliated technical field
The utility model relates to a kind of petroleum production pumping unit, especially relates to a kind of oil pump speed reducer lubricating fitting.
Background technique
The retarder of pumping unit is based on two circular arc herringbone tooth retarders, 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 by gear band, and lubricant oil flows on the bearing along cover wall, flows in the casing by 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
When having the oil pump speed reducer low-speed running now in order to overcome, drive shaft bearing can not get sufficient lubrication, the deficiency that causes damage of bearings, the utility model provides a kind of oil pump speed reducer lubricating fitting, and this oil pump speed reducer lubricating fitting can be good at satisfying the lubricated of drive shaft bearing under the low-speed running state.
The technological scheme that its technical problem that solves the utility model adopts is: the oil pump speed reducer lubricating fitting comprises speed reducer casing, driving shaft, drive shaft bearing, on the speed reducer casing parallel with driving shaft oil box is installed, oil box has oil-scrapping sheet near driving shaft diameter of axle place; One end of oil pipe line is connected with oil box, and the other end is near drive shaft bearing; The end that oil pipe line is connected with oil box is higher than the other end near drive shaft bearing.
The beneficial effects of the utility model are, and are simple in structure, easy for installation, have the pressure lubrication function, can guarantee retarder when low-speed running, and drive shaft bearing obtains sufficient lubrication, avoids causing damage of bearings because of lack of lubrication.
Description of drawings
Fig. 1 is the utility model oil pump speed reducer lubricating fitting structural representation.
Fig. 2 is the A-A sectional view of Fig. 1.
Among the figure: 1. oil-scrapping sheet, 2. oil box, 3. oil pipe line, 4. drive shaft bearing, 5. driving shaft, 6. speed reducer casing.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
With reference to accompanying drawing 1 and accompanying drawing 2.The utility model oil pump speed reducer lubricating fitting comprises speed reducer casing 6, driving shaft 5, drive shaft bearing 4, on the speed reducer casing 6 parallel with driving shaft 5 oil box 2 is installed.Outwards extend in the two ends of oil box 2, an end is wherein fixedlyed connected with speed reducer casing 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 pipe line 3 is connected with oil box 2; The other end is near drive shaft bearing 4, and oil pipe line 3 outlets are positioned at the rolling element place of drive shaft bearing 4 lower ends.The end that oil pipe line 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 oil pump speed reducer lubricating fitting is as follows, lower when driving shaft 5 rotating speeds of oil pump speed reducer, when gear can't take up lubricant oil and splash, the oil-scrapping sheet 1 that front end upwarps slightly scrapes the lubricant oil on the driving shaft 5, the lubricant oil that scrapes is in oil-scrapping sheet 1 flows to oil box 2, oil in the oil box 2 passes through oil pipe line 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.
Claims (2)
1. oil pump speed reducer lubricating fitting, comprise speed reducer casing, driving shaft, drive shaft bearing, it is characterized in that: on the speed reducer casing (6) parallel with driving shaft (5) oil box (2) is installed, oil box (2) has oil-scrapping sheet (1) near driving shaft (5) diameter of axle place; One end of oil pipe line (3) is connected with oil box (2), and the other end is near drive shaft bearing (4); The end that oil pipe line (3) is connected with oil box (2) is higher than the other end near drive shaft bearing (4).
2. oil pump speed reducer lubricating fitting according to claim 1 is characterized in that: the quantity of described oil box (2) is 2.
