Abstract
The utility model relates to an oil receiving pan type lubricating device for a speed reducer of a pumping unit and aims to solve the following problems: a driving shaft of the traditional speed reducer is not provided with a lubricating device, so that when the pumping unit pumps less than four times, a bearing can not be lubricated. An oil receiving pan is mounted below a driving shaft gear of the speed reducer and a driven gear in engaging transmission with the driving shaft gear and fixed on the end surface of a tank seat through a sealing gasket, a bolt and a spring; an oil cavity of the oil receiving pan is higher than the frication surface of the bearing; an oil return hole communicated with an oil path of the frication surface and a lubricating oil pool is formed on an external tank seat of the bearing. When the driving wheel rotates, the driving gear is engaged and in contact with the driven gear, the driven gear rotates to suck lubricating oil from the lubricating oil pool and stick to the driving shaft gear, and under the functions of gravity and centrifugal force, the lubricating oil can fall into the oil receiving pan with a distance of 10mm away from the driving gear and the driven gear and flows into the bearing for lubrication through the oil receiving pan, therefore, the bearing can be fully cooled; after cooling the bearing, the oil is discharged to the oil pool through the oil return hole of the tank seat and continuously sucked by the driven gear, so that the lubricating oil can be recycled. The lubricating device can be used for lubricating cooling of the driving shaft gear of the speed reducer of the pumping unit.
Description
(1) technical field: the utility model relates to a kind of lubricating arrangement that is used for the cooling of oil pump speed reducer drive shaft bearing.Belong to transmission device class (F16H).
(2) background technology: the reducer that conventional pumping unit is used, its driving shaft are not generally established lubricating arrangement, and the oil groove of the oil that the lubricated dependence driving shaft of drive shaft bearing splashes on block flows into bearing and lubricate drive shaft bearing.But development along with oil pumper, require oil pumper to have lower jig frequency, when the jig frequency of oil pumper be lower than 4 towards the time, driving shaft can be crossed the low lubrication oil that splashes on the driving shaft of causing and can't lubricate because of the drive shaft bearing that causes of the oil groove that can't enter block owing to rotating speed.
(3) summary of the invention:
The oil pump speed reducer driving shaft oil drain pan formula lubricating arrangement that the utility model provides solves existing oil pump speed reducer driving shaft exactly and does not establish lubricating arrangement, when the jig frequency of oil pumper be lower than 4 towards the time, the problem that causes drive shaft bearing to lubricate.
Its technical scheme is as follows:
Oil pump speed reducer oil drain pan formula lubricating arrangement comprises that lubricating oil bath is arranged at the bottom in the reducer block, and the both ends of main drive shaft bearings has the spill port that lubrication oil is entered oil sump on the block on the reducer block, it is characterized in that:
1) below the driven pulley place of the reducer driving shaft gear and the transmission that is meshing with each other, establishes oil drain pan; 2) oil drain pan is fixed in the reducer block medial surface of drive shaft bearing below by sealing mat, nut and the bullet pad that is provided with; 3) height and position of oil drain pan setting is to make the oil drain pan oil pocket be higher than bearing friction face; Oil circuit that bearing friction face forms and spill port are communicated with.
The concrete parameter of the technical program etc. is chosen in the back accompanying drawings.
The beneficial effects of the utility model: below driving shaft, install an oil drain pan additional, as long as driving shaft and passive helical gear contact, lubrication oil on the helical gear will be bonded on the driving shaft gear, these lubrication oil can since gravity and action of centrifugal force fall into be installed in its following from it apart from the oil drain pan that has only about 10mm, and through oil drain pan inflow drive shaft bearing, guarantee that drive shaft bearing has sufficient lubrication oil, thereby thoroughly solved the lubrication problem of reducer under low jig frequency.

2To schematic diagram (oil drain pan assembly plan view).
(5) specific embodiment:
See Fig. 1-Fig. 3, be provided with in the oil pump speed reducer: the driven helical teeth opinion 4, driving shaft 7, the drive shaft bearing box 8 that fill the oil sump 6, driving shaft gear 2, drive shaft bearing 3 of certain altitude lubrication oil in reducer block 5, the block, be in transmission connection with driving shaft.Bearing 3 is supported on the reducer block 5.See Fig. 3, have on the outer block 5 of bearing lubrication oil is entered the axial spill port 5.1 of oil sump, vertical spill port 3.2.
See Fig. 3, below driven pulley 4 places of the reducer driving shaft gear 2 and the transmission that is meshing with each other, establish oil drain pan 1; Oil drain pan apart from driving shaft gear along the short transverse distance, delta
1Be taken as 10mm.
See Fig. 3, Fig. 5, oil drain pan is fixed on reducer block 5 medial surfaces below the drive shaft bearing 3 by sealing mat 1.1, nut 1.3 and the bullet pad 1.2 that is provided with; See Fig. 3, Fig. 4, the height and position of oil drain pan setting is to make oil drain pan oil pocket 1.1 be higher than bearing friction face 3.1.
The course of work:
When driving shaft 7 rotates, after driving shaft gear 2 contacts with passive helical gear 4 engaged transmission, passive helical gear rotates lubrication oil in the oil sump 6 is sucked, and can be bonded on the driving shaft gear, these lubrication oil can since gravity and action of centrifugal force fall into be installed in its following from it apart from the oil drain pan 1 that has only about 10mm, when bearing inner race rotates with driving shaft, lubrication oil is inhaled into bearing friction face 3.1 in the oil drain pan, in bearing, carry out lubricated fully, guarantee that bearing fully cools off, lubrication oil behind the cooling bearing flows into the axial spill port 5.1 of block through the vertical spill port 3.2 of bearing, enter oil sump 6 again and suck continuously, lubrication oil circulation is used with this for driven gear.
