Abstract
The present invention relates to a face cam of cleaning machine, it is applicable for driving several groups of plunger components of high pressure plunger pump to make them implement axial reciprocating movement in turn so as to implement high pressure light output. It is characterized by that its working surface is a spherical recess ball track which can make rolling friction with ball of thrust rolling bearing, and can be directly used as ball track of thrust rolling bearing. It is made up by using high-quality carbon steel through the stamping forming process, and on the surface of ball track the alloy elements of tungsten and molybdenum are infiltrated, then it is undergone the processes of carbonization and heat treatment so as to make ball track portion directly form high-quality material with high-speed tool steel characteristics.
Description
Technical field
The present invention relates to a kind of washing machine face cam, especially relate to a kind of face cam of high-pressure plunger type water pump cleaning machine; It is applicable to that mainly the many groups plunger assembly that promotes high-pressure plunger pump makes axially reciprocating successively, to finish the output of highly pressurised liquid.
Background technique
The face cam 101 of existing high-pressure plunger type water pump cleaning machine, its groundwork surface are a garden planar annular 102, as shown in Figure 3; When motor 104 rotates, electric machine main shaft 102 drives face cam 101 rotations, the interior ring 105 of thrust bearing is posted by the garden planar annular 102 of face cam, the another side of ring 105 is then done rolling friction with the ball 106 of thrust bearing in being somebody's turn to do, and simultaneously the plunger piston assembly of forming by many groups plunger, piston spring etc. to the previous crops axial motion, and under the piston spring effect, make backward axially reseting movement respectively successively, face cam whenever revolves and turns around, the plunger piston assembly of many groups is made axially reciprocating once successively, just with low pressure water source P in the pump
2Be press-fit into high pressure exhalant region P
1, so move in circles and in hyperbaric chamber, set up constant working pressure.Yet, the interior ring 105 of bearing requires height because being posted by the contact precision on the ring plane 102 of face cam, could guarantee the running precision and the stationarity of high-pressure plunger type water pump cleaning machine, and in fact the interior ring 105 of described bearing all is to produce certain machining error in manufacture process with face cam 101, brings influence therefore for the running precision and the stationarity of high-pressure service pump washing machine.
Summary of the invention
Technical problem to be solved by this invention provides and a kind ofly can reduce contacting link and rotary inertia, improve the simple and reasonable plane cam for high-pressure plunger type water pump cleaning machine of transmission stiffness, stability and operational efficiency between face cam and the thrust bearing.
The present invention solves the problems of the technologies described above the technological scheme that is adopted: employing ball direct by face cam and rolling bearing is made the project organization of rolling friction, omits the interior ring of a thrust bearing; Its working procedure is such: the rotation of driven by motor face cam, a spherical groove is arranged on the interior conocave plane of face cam, it directly contacts with the ball of thrust bearing and does rolling friction, the ball of same thrust bearing and the outer ring of thrust bearing are done rolling friction, and transmission of power organized the plunger piston assembly be made up of plunger, piston spring etc. at the most to the previous crops axial motion, and under three piston spring effects, make backward axially reseting movement respectively successively; It has a tightening wall and a motor shaft bowl-shape, that be connected and fixed usefulness with motor shaft to be connected and fixed with screw.Face cam whenever revolves and turns around, and the plunger piston assembly of many groups is made axially reciprocating once successively, just low pressure water source in the pump is press-fit into the high pressure exhalant region, so moves in circles and set up constant working pressure in hyperbaric chamber.According to connected system flexibility theory, the general flexibility of face cam and thrust bearing is each attachment portion flexibility sum, promptly
