Abstract
The invention discloses a pin roller sliding vane vacuum pump. The pin roller sliding vane vacuum pump comprises a shell and a sliding vane, wherein the sliding vane is rotatably installed in the shell; two cylindrical pin rollers are installed at two ends of the sliding vane through a movable centrifugal action member; the pin rollers and the centrifugal action member contact with the profile of the shell under the action of a centrifugal force; the centrifugal action member comprises a small vane, wherein the small vane is embedded in a slot at two ends of the sliding vane and a gap is respectively reserved between the small vane and the end parts of the sliding vane; a slot and a concave arc plane are machined in the small vane; the pin rollers can be installed in the slot in free rotation so as to be adhered to the concave arc plane tightly; the pin rollers can rotate in the slot freely; and a taper angle D is machined in the front of the small vane. According to the pin roller sliding vane vacuum pump provided by the invention, compared with the traditional vacuum pump, the sliding friction between the head of the small vane and the profile of the shell is changed into rolling friction, the abrasion resistance of the vacuum pump is improved on the premise that the sealability is not reduced, thereby greatly reducing manufacturing cost and simultaneously improving the service life of the vacuum pump.
Description
Technical field
The present invention relates to the rotary slide sheet vacuum pump that a kind of automobile is used, relate in particular to a kind of roller sliding vane vacuum pump.
Background technique
At present, existing automobile is used the rotary slide sheet vacuum pump structure, with reference to the Chinese patent publication number is: CN101002021A; Denomination of invention is: single vane vacuum pump, and this Chinese patent discloses sliding-vane-type vacuum pump as shown in Figure 1, and its housing molded lines is the envelope of appellation conchoid on a kind of mathematics in theory; When rotor 2 drives slide plate 3 high-speed rotation; The circular arc at the two ends of slide plate 3 should keep in touch with housing molded lines 1 always in theory, so that form Seal cage, produces vacuum.In fact slide plate 3 two ends install two activities circular arc small leaf 4; It is embedded in 3 liang of end slots 3.1 of slide plate; Slide plate 3 is gapped with small leaf 4, by centrifugal force small leaf 4 front end circular arcs 4.1 is close on the housing profile 1 when slide plate 3 rotates and slides, because the vacuum pump rotating speed is very high; Sliding velocity is very big between small leaf 4 and the housing molded lines 1, and fricative high temperature reaches degree more than 200.So small leaf 4 must adopt high temperature resistant, wear-resisting material.Be the special plastic that adopts expensive heat resistant and wear resistant at present, its price is about 1/3 of a whole vacuum pump cost.
Therefore, how to reduce the small leaf head and housing between frictional force, prolonging its life-span is one of importance of improving the vacuum pump performance.
Summary of the invention
The object of the present invention is to provide a kind of roller sliding vane vacuum pump, adopt rolling friction between its slide plate and the housing molded lines, reduce the frictional force of small leaf head, reduce heating value,, improve the working life of whole slide plate to improve the wear resistance of small leaf head.
For reaching this purpose, the present invention adopts following technological scheme:
A kind of roller sliding vane vacuum pump; It comprises housing and the rotating slide plate that is installed in the housing; Wherein, two cylinder rollers are installed through mobilizable centrifugal action parts in the two ends of said slide plate, and said roller and centrifugal action parts contact with the housing profile under centrifugal action.
Especially; Said centrifugal action parts comprise small leaf; Said small leaf be inlaid in the groove at slide plate two ends and and the end of slide plate between have the gap, be processed with groove and concaved circular cambered surface in the small leaf, being contained in the groove that roller is free to rotate is close to concaved circular cambered surface; Roller can freely rotate in groove, is processed with cone angle D before the small leaf.
Especially; Said centrifugal action parts comprise compensation block; Inside groove and water jacket are all opened in the slide plate two ends, and processing cone angle D, and what roller was free to rotate is contained in the water jacket; Said compensation block is installed in the inside groove and under action of centrifugal force, can moves along inside groove, has the gap h of 0.02～0.1mm between said compensation block and the slide plate.
Especially, said cone angle D is between 30 °～90 °, and said roller center and slide plate identity distance foremost leave A at 0.5～1.5mm.
Especially, the inner of said small leaf is provided with some soft springs, and vacuum pump is when beginning to start, and rotating speed is lower, and centrifugal force is little, and spring force has improved the pressure of roller and housing, the sealing when improving low speed.
Especially, offer several through holes on the said slide plate, to alleviate the weight of slide plate.
Beneficial effect of the present invention is that the sliding friction that said roller sliding vane vacuum pump is compared between original small leaf head and the housing profile with traditional vacuum pump becomes rolling friction, is not reducing its wear resistance of raising under the sealing prerequisite.Roller can be used wear-resisting Chilled Hardened Steel, reduces manufacture cost so greatly, has improved vacuum pump working life simultaneously.

Embodiment
Further specify technological scheme of the present invention below in conjunction with accompanying drawing and through embodiment.
Embodiment one:
See also shown in Figure 2ly, Fig. 2 is the structural representation of the roller sliding vane vacuum pump that provides of the specific embodiment of the invention 1.
In the present embodiment; As shown in the figure, be inlaid in the groove 3.1 at slide plate 3 two ends as the small leaf 4.4 of roller seat, slide plate 3 ends 3.3 are h with small leaf 4.4 gaps; Small leaf 4.4 front ends are processed with straight trough 4.5; The width of groove is than the big 0.05-0.1mm of roller 4.2 diameters, and roller 4.2 can freely rotate in groove 4.5, and circular arc 4.6 is fitted in roller 4.2 cylindricals and the small leaf 4.4.This moment small leaf 4.4 preceding Transverse plane 4.7 and roller 4.0 centre distances greater than 0.5, but can not be too big, in the time of guaranteeing that slide plate 3 rotates; When the groove 3.1 band small leaf 4.4 on the slide plate 3 rotated, the groove 4.5 on the small leaf 4.4 promoted roller 4.2, and roller 4.2 is contacted with housing profile 1; Centrifugal force during slide plate rotation simultaneously makes slide plate 3; End face 3.3 is pressed on the small leaf 4.4, makes the intersection 4.3 of cone angle D and face 4.7 on the small leaf 4.4, near housing molded lines 1.The size of correct selected angle D and distance A is guaranteed roller 4.2 when housing molded lines 1 moves, and intersection 4.3 does not collide with housing molded lines 1.
