Abstract
The invention discloses an eccentric type tamping pickax with self-lubrication function, belonging to mechanical field of railway maintenance, which is characterized in that: a central hole and a lateral aperture are processed on an eccentric shaft which is provided with an oil suction nozzle at the lower end; an oil seal arranged at the upper end of the rod shell enables the rod shell form a confined space; a partial pressure gland bush is arranged in a hole at the lower end of the rod shell; the bearing and the partial pressure gland bush enable the confined space to form an upper and a lower parts with lubrication oil arranged at the lower part. When the momentum of a gasoline engine passes through a clutch and a flexible shaft drives an eccentric shaft to rotate to produce vibration, the eccentric part of the eccentric shaft drives the air flow at high speed, thereby enabling the pressure at the upper part of the confined space smaller than the pressure at the lower part; under the action of pressure difference, the lubricating oil flows to the upper part of the bearing through the central hole and the lateral aperture and flows back to the lower end through the bearing under the gravity action, thereby forming a circulation; on one hand, the flowing of the lubrication oil lubricates the bearing and takes away the hot energy produced by high-speed rotation of the bearing on the other hand, thereby prolonging service life of the bearing.
Description
One, technical field
The invention belongs to the railway maintenance mechanical field.
Two, background technology
A kind of " internal combustion Direct Action Type tamping tool " that Chinese patent application number " 01261646 " provides does power with gasoline engine, drive the eccentric shaft rotation by flexible axle and produce vibration, the bearing rotating speed that supports eccentric shaft up to 7000 rev/mins about, machine is made radiating condition firm by ramming in ballast aggregate poor, there is not effective lubricating again, therefore the bearing damage of very easily generating heat influences the normal use of machine.
Three, summary of the invention
Purpose of the present invention is exactly to design a kind of tamping pickaxe that has self-lubricating function, improves the lubricating condition and the radiating condition of bearing, improves bearing life, satisfies abominable working condition requirement.
The technical scheme that the present invention solves its technical problem employing is: the output of gasoline engine clutch connects flexible axle, the flexible axle other end connects with eccentric shaft, the eccentric shaft up/down steps respectively is equipped with two bearings, bearing is contained in the excellent shell, rod shell lower end connects pick, in the rod shell upper end hole oil seal seat is housed, oil sealing is housed in the oil seal seat, the oil sealing endoporus cooperates with the eccentric shaft cylindrical of topping bar, make airtight space of the interior formation of excellent shell of oil sealing bottom, in the stomidium branch gland is housed under the rod shell, two bearings of eccentric shaft lower end and divide gland again the confined space of excellent shell to be divided into two parts up and down, on eccentric shaft, be processed with centre bore and side opening, centre bore and side opening communicate, the lower end of eccentric shaft is connected with oil-Absorbing nozzle, lower cavity is equipped with lubrication oil, gasoline engine power is through centrifugal clutch, reach flexible axle, flexible axle drives eccentric shaft and rotates the vibrative while, the eccentric shaft eccentric part drives the ambient air flow at high speed, the pressure that makes confined space top is less than base pressure, produce pressure differential, under the effect of pressure reduction, lubrication oil is through fuel sucking pipe, above eccentric shaft centre bore and the side opening inflow upper end bearing, under the effect of gravity, flow back into the bottom through bearing again, form circulation, the mobile one side lubricating bearings of lubrication oil is taken away the heat that bearing rotates generation at a high speed on the other hand.
The invention has the beneficial effects as follows: rely on the eccentric shaft rotation to drive the ambient air flow at high speed and produce pressure differential up and down, make lubrication oil be drawn to the bearing upper end, flow back into the lower end by bearing again, form circulation, lubricating bearings is taken away heat, significantly improve the lubricating condition and the radiating condition of bearing, improve bearing life.
