Abstract
The utility model discloses a high pressure cleaner plunger pump gearing, comprising a box body(1), a middle cover(11), a transmission shaft(2), a big annular gear(5), a swash plate(6) and a plunger(10); wherein, the middle cover(11) is fixed at the box body(1), the transmission shaft(2) is arranged between the box body(1) and the middle cover(11), the swash plate(6) is arranged at the transmission shaft(2) through a radial ball bearing(4), the big annular gear(5) having an interference fit is arranged at the swash plate(6), a thrust bearing(3) is arranged between the internal side of the swash plate(6) and the internal end face of the box body(1), a thrust bearing(7) is arranged at the inclined plane outside the swash plate(6), and the bulb of the plunger(10) is contacted with the working face of the thrust bearing(7). Adopting the structure above, the utility model solves the problems that the swash plate and the plunger have a quick wearing and the radial ball bearing(4) has a short service time.
Description
Technical field
The utility model relates to a kind of transmission device, the transmission device between particularly a kind of jetting machine motor and the plunger displacement pump.
Background technology
Present plunger-type pump of high pressure cleaner transmission device generally is made up of casing, middle cover, power transmission shaft, bull gear, swash plate, plunger, middle cover is fixed on the casing, power transmission shaft is arranged between casing and the middle cover, swash plate is installed on the power transmission shaft by radial ball bearing, the bull gear interference fit is installed on the swash plate, plunger directly contacts with the inclined-plane, the outside of swash plate, during work, motor output shaft is by gear driven bull gear and swash plate rotation, the inclined-plane, the outside that plunger contacts with swash plate constantly changes, thereby it is reciprocating to promote plunger; The weak point that this structure exists: the one, the thrust of plunger acts directly on the swash plate, causes the composition surface wearing and tearing of swash plate and plunger very fast, and the plunger operating efficiency is descended, and causes plunger displacement pump to lose efficacy when serious; The 2nd, the thrust of plunger passes to radial ball bearing by swash plate, and it is excessive to cause radial ball bearing to bear axial force, rotates not steadily, shortens service life of radial ball bearing.For this reason, many manufacturers and knowledgeable people have carried out research repeatedly, but do not have ideal method to solve the problems referred to above so far as yet.
Summary of the invention
For overcoming the disadvantage of above-mentioned existence, the purpose of this utility model provides that a kind of simple and reasonable, stability of rotation, wearing and tearing are little, the plunger-type pump of high pressure cleaner transmission device of long service life, good reliability.
The technical scheme that its technical problem that solves the utility model adopts, it comprises casing, middle cover, power transmission shaft, bull gear, swash plate, plunger, middle cover is fixed on the casing, power transmission shaft is arranged between casing and the middle cover, swash plate is installed on the power transmission shaft by radial ball bearing, and the bull gear interference fit is installed on the swash plate, is provided with thrust bearing between swash plate inboard and casing inner face, be provided with thrust bearing on inclined-plane, the swash plate outside, the bulb of plunger contacts with the thrust bearing working face.
Described plunger is provided with spring pad and plunger spring, is provided with the plunger oil sealing on the plunger in the middle cover outside.
Described bull gear cooperates with gear on the motor output shaft.
After adopting said structure following advantage is arranged, the one, the bulb of plunger contacts with the thrust ball bearing working face, and it is less therefore to wear and tear each other, has overcome the bulb and the big defective of swash plate sliding frictional wear of original structure plunger; The 2nd, the influence of the axial thrust that radial ball bearing is produced when no longer being subjected to plunger work, only play radial support and guide effect, and axial thrust is directly passed to casing by thrust bearing, swash plate, thrust bearing, make the thrust in the transmittance process reach balance, therefore, stability of rotation, thus service life of radial ball bearing prolonged greatly.
