Description
Technical field
The utility model relates to vacuum pump technology field, is specifically a kind of camshaft integrated form vacuum pump.
Background technique
At present, comparatively common camshaft vacuum pump, its camshaft, rotor, coupling are generally three independent parts, three needs to carry out assembling assembling, and not only step is more when assembling, assemble more loaded down with trivial details, and three's reason is assembled, more or less there is the assembly error produced because of assembling, affect the coaxial accuracy of three to a certain extent.
In addition because rotor installs blade by the opening slot of open-topped, such blades installation in this opening slot after, vane tip just directly contacts with pump housing cover plate, like this when blade bottom is subject to lubricant oil impact force upwards, vane tip just can and pump housing cover plate between rub continuously, vane tip is worn and torn, has a strong impact on the working life of blade.
Model utility content
The technical problems to be solved in the utility model is, provide a kind of simple for structure, without the need to assembling, effective guarantee coaxality, and effectively can avoid blade wear, extend the camshaft integrated form vacuum pump in blade working life.
For solving the problems of the technologies described above, the technological scheme that the utility model provides is: comprise the pump housing, camshaft, blade, be loaded on the rotor of pump housing inner chamber, the lower end of rotor forms linkage section and rotor is integral type structure by this linkage section and camshaft, rotor is provided with mounting hole radially, blade is unsettled to be loaded in mounting hole, mounting hole below blade forms the lower oil suction chamber entered for lubricant oil, the symmetrical oil groove offering lower end and be communicated with lower oil suction chamber vertically on the two side of mounting hole, the top of rotor is provided with the capping for covering oil groove, the second oil suction chamber entered for lubricant oil is formed between capping and vane tip.
The cross section of described oil groove is semicircle, and described capping is circular closure.
The bottom of described blade and top are equipped with the square aperture groove being convenient to lubricant oil circulation along its length, and the two ends of square aperture groove extend to the two ends of blade respectively.
Camshaft integrated form vacuum pump linkage section of the present utility model replaces the coupling of prior art, and by this linkage section by rotor and the integral formula structure of camshaft design, make rotor, linkage section becomes as a whole with camshaft, be component, terminal with compact integral structure is a lot, not only eliminate the assembling of multiple component as prior art, simultaneously as a whole rotor, linkage section and camshaft coaxial accuracy high, avoid and affect coaxial accuracy because of assembly error as prior art, additionally by mounting hole, oil groove, the blade of capping and unsettled setting, vane tip is made also to be formed with oil suction chamber, like this when lubricant oil still can continue by oil groove to enter into upper oil suction chamber after the lower oil suction chamber of blade bottom enters, all there is lubricant oil at such blade bottom and top, under the effect of bottom and top lubricant oil oil pressure, blade is in state of suspension, the top of such blade just directly can not touch capping, so do not have wearing and tearing, effectively extend the working life of blade.
Further, the cross section of described oil groove is semicircle, described capping is circular closure, cross section is semicircular oil groove by after being symmetrical arranged, just can the conglobate oil duct of shape, just can arrange circular capping like this at the top of circular oil duct, circular and semicircle processing simultaneously also facilitates, and overall structure is also succinct.
Further, the bottom of described blade and top are equipped with the square aperture groove being convenient to lubricant oil circulation along its length, the two ends of square aperture groove extend to the two ends of blade respectively, and after the arranging of square aperture groove, oil just can be passed through this opening slot and lubricating blade.
Accompanying drawing explanation
Accompanying drawing is the broken section structural representation of the utility model camshaft integrated form vacuum pump.
Shown in the utility model figure: 1 pump housing, 2 camshafts, 3 blades, 3.1 square aperture grooves, 4 rotors, 4.1 mounting holes, 4.2 oil grooves, 5 linkage sections, 6 times oil suction chambers, 7 cappings, 8 second oil suction chambers.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in the figure, camshaft integrated form vacuum pump of the present utility model, comprises the pump housing 1, camshaft 2, blade 3, is loaded on the rotor 4 of the pump housing 1 inner chamber.
Unlike the prior art, the lower end of rotor 4 forms linkage section 5 and rotor 4 is integral type structure by this linkage section 5 and camshaft 2.For namely becoming component after integral type structure, eliminate the assembling procedure of each component like this, coaxality also can obtain effective guarantee simultaneously.
Rotor 4 is provided with mounting hole 4.1 radially, and shape, the size of the shape of this mounting hole 4.1, size and blade match, and in the present embodiment, because blade is rectangular, therefore mounting hole 4.1 is also rectangular.Blade 3 is unsettled to be loaded in mounting hole 4.1, and wherein unsettled installation is actually between the bottom of blade and the diapire of mounting hole and leaves distance, and the two ends of the bottom of blade are then placed on pump housing bottom wall of inner cavity, so just can complete the unsettled installation of blade.
Mounting hole 4.1 below blade 3 forms the lower oil suction chamber 6 entered for lubricant oil, the symmetrical oil groove 4.2 offering lower end and be communicated with lower oil suction chamber 6 vertically on the two side of mounting hole 4.1, the top of rotor 4 is provided with the capping 7 for covering oil groove 4.2, forms the second oil suction chamber 8 entered for lubricant oil between capping 7 and blade 3 top.
The cross section of described oil groove 4.2 is semicircle, and described capping 7 is circular closure.
The bottom of described blade 3 and top are equipped with the square aperture groove 3.1 being convenient to lubricant oil circulation along its length, and the two ends of square aperture groove 3.1 extend to the two ends of blade 3 respectively.
The rotor of camshaft integrated form vacuum pump of the present utility model, linkage section, camshaft are integral type structure, and three is as a whole, become component, effectively simplify the structure, eliminate the assembling of each parts simultaneously, and effective guarantee coaxality.Additionally by the setting of upper oil suction chamber, under the effect of lubricant oil oil pressure, blade is in state of suspension between capping plate and linkage section, avoids the wear phenomenon that vane tip causes with direct contact of capping, improve the serviceability of blade, extend working life.
