Description
Technical Field
The utility model relates to the field of lubricating structures for reciprocating pumps, in particular to a built-in lubricating structure for a pump meeting the working condition of large-angle inclination and impact.
Background
In a reciprocating pump for a ship, since the pump is mounted on the ship and floats on the water surface with the ship, the pump has an inclined working condition, and the maximum angle can reach 50 degrees, which causes lubricating oil in the pump to flow to one side and causes the other side to be free of lubricating oil. The rolling bearing of the conventional reciprocating pump adopts splash lubrication, and the lubricating oil can only lubricate the bearing on one side under the working condition of large-angle inclination, and the bearing on the other side is not lubricated by the lubricating oil, so that the operation of the pump is influenced.
Disclosure of utility model
The utility model aims to provide a built-in lubricating structure of a pump meeting large-angle inclined and impact working conditions, which can lubricate under any working conditions, meet the adaptability of the pump to inclined and impact working conditions and improve the reliability of the pump.
In order to achieve the above purpose, the utility model adopts the following technical scheme: the utility model provides a satisfy built-in lubricating structure of large-angle slope, impact operating mode pump, includes bent axle, pump case, and the bent axle both ends are installed on the pump case through antifriction bearing, and the bent axle is inside to be equipped with the lubrication oil duct, has offered the lubricating oil mouth that spouts towards antifriction bearing roller on the first crank in bent axle both ends, and lubricating oil spouts the hydraulic fluid mouth and lubricates the oil duct intercommunication.
Preferably, as an improvement, an oil filling port communicated with the lubricating oil duct is formed at one end of the crankshaft.
Preferably, as an improvement, the lubricating oil duct is formed by communicating lubricating oil holes formed in each crank, each connecting rod journal and each main journal.
Preferably, as a modification, the axis of the lubrication hole is parallel or perpendicular to the main axis of the crankshaft.
Preferably, as an improvement, the opening ends of the other lubricating oil holes are all in threaded connection with plugs except the lubricating oil spraying port.
The principle of the scheme is as follows: when the device is in practical application, the rolling bearings are arranged at the two ends of the crankshaft of the reciprocating pump to rotatably support the crankshaft, lubricating oil is injected into the crankshaft through the oil injection port, the lubricating oil is sprayed out from the lubricating oil injection ports at the two ends of the crankshaft after forced pressurization, the lubricating oil injection port is arranged on the end faces of the cranks at the two ends of the crankshaft, facing the rolling bearings, of the rollers, and the lubricating oil is directly sprayed to the roller parts. In the continuous rotation process of the crankshaft, the lubricating oil injection port also continuously rotates, lubricating oil is circumferentially sprayed on the rolling bearing, the whole circle of bearing rollers are lubricated, the rolling bearings at the two ends of the crankshaft can be effectively lubricated even if the reciprocating pump is in an inclined state, and the full lubrication of the rolling bearings in the full working condition period is realized.
The utility model has the advantages that the lubricating requirement of the rolling bearing of the reciprocating pump under the working condition of large-angle inclination is met, the problems of complicated pipelines and oil leakage of the pipelines are avoided by the built-in oil circuit system, the cost is low, and the adaptability and the reliability of the reciprocating pump are improved. Built-in integral type lubricating structure, no weak oil circuit pipeline, avoid connecting not hard up and appear the oil leak after the impact, lead to the pump package lubricating oil not enough scheduling problem, satisfy pump package shock resistance. The whole circle of bearing rollers can be lubricated, so that the lubricity of a bearing friction pair is enhanced, the abrasion of the bearing is reduced, and the service life of the bearing is prolonged.
Drawings
Fig. 1 is a schematic structural diagram of an embodiment of the present utility model.
Detailed Description
The following is a further detailed description of the embodiments:
Reference numerals in the drawings of the specification include: pump case 1, lubricating oil injection port 2, roller 3, rolling bearing 4, connecting rod journal 5, lubricating oil hole 6, crankshaft 7, lubricating oil duct 8 and crank 9.
An example is substantially as shown in figure 1: the utility model provides a satisfy built-in lubricating structure of large-angle slope, impact operating mode pump, includes bent axle 7, pump case 1, and the bent axle 7 both ends are installed on pump case 1 through antifriction bearing 4, and bent axle 7 is inside to be equipped with lubrication oil duct 8, and lubrication oil duct 8 is by seting up at every crank 9, connecting rod journal 5, the inside lubrication oil hole 6 intercommunication of main journal and constitute, and the axis of lubrication oil hole 6 is parallel or perpendicular with the main axis of bent axle 7. One end of the crankshaft 7 is provided with an oil filling port communicated with the lubricating oil duct 8. The first crank 9 at the two ends of the crankshaft 7 is provided with a lubricating oil injection port 2 facing the roller 3 of the rolling bearing 4, and the lubricating oil injection port 2 is communicated with a lubricating oil duct 8. The opening ends of the other lubricating oil holes 6 are all in threaded connection with plugs except the lubricating oil spraying port 2.
The specific implementation process is as follows: the crankshaft 7 is filled with forced pressurized lubricating oil through an oil filling port at the end part, and the lubricating oil hole 6 is closed through a plug, so that the lubricating oil duct 8 only discharges the lubricating oil outwards through the lubricating oil filling port 2 at the two ends of the crankshaft 7. The reciprocating pump using the crankshaft 7 is in an inclined working condition or not, the lubricating oil injection port 2 synchronously rotates in the rotation process of the crankshaft 7, and the lubricating oil injection port 2 can continuously spray lubricating oil at the positions of the rollers 3 of the rolling bearing 4 in the circumferential direction, so that the whole circle of the rollers 3 are lubricated. The lubricating oil duct 8 built in the crankshaft 7 avoids complicated oil-way pipelines, also avoids the problem of loose oil leakage caused by connection of the oil-way pipelines after impact, and remarkably improves the adaptability and reliability of the reciprocating pump, so that the reciprocating pump can stably work under the working conditions of equal large inclination and impact of a ship.
