Description
Technical field
The utility model relates to a kind of vacuum pump, and more particularly, it relates to a kind of rotor for vacuum pump.
Background technique
At present, motor car engine is all furnished with vacuum pump mostly, and this vacuum pump is used as the vacuum power source of the systems such as brake power-assisted, cruise, airconditioning control.Traditional automobile vacuum pump mostly is blade type, comprise the pump housing, pump cover, rotor, blade, there is offset distance at the intracavity sidewall center of rotor and the pump housing, blade is positioned at rotor and can rotates along with rotor, and its end and intracavity sidewall keep in touch, side, the bottom surface of blade and pump housing inner chamber form Seal cage, in vacuum pump rotary course, pump housing inner chamber is separated into zone of high pressure and low pressure area by blade, along with the consecutive variations of sealed volume, air in vacuum tank is extracted out, in vacuum system, forms vacuum.In the process, due to rubbing contact all the time between inside blade and intracavity sidewall and rotor, therefore very easily wear and tear, and along with the wearing and tearing of blade, frictional loss also constantly increases, the gap of blade and intracavity sidewall and rotor becomes large simultaneously, cause sealing to reduce, whole efficiency reduces further, thus causes the engine power of consumption to make idle work greatly, therefore, lasting rotor is lubricated is needed.
Now commercially there is the vacuum pump rotor of some single blades to utilize stable rotational structure, its rotor does not design some structures of conveniently carrying out lubricating mostly.And in the process of rotor turns, need the oil groove carrying out lubricating to need structurally to coincide with rotor structure, guarantee stablizing in rotary course.
Model utility content
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of rotor for vacuum pump, add the casting lug thereon for guaranteeing blade stable rotation in both sides, then add oil groove and oilhole in casting lug thereon both sides, guarantee that rotor both sides in rotation process are evenly lubricated.
For achieving the above object, the utility model provides following technological scheme: a kind of rotor for vacuum pump, comprise columned rotor body, described rotor body offers groove, described rotor body opposite side is provided with the draw-in groove with the clamping of rotating shaft clamp, described rotor body outer wall is provided with two symmetrical casting lug thereons, described casting lug thereon is circular arc, described rotor body be provided with for blade axially across through hole, the two ends of described through hole are corresponding with the gap between described casting lug thereon, described casting lug thereon side is provided with some oil grooves, described oil groove is evenly distributed in described casting lug thereon, described casting lug thereon opposite side is provided with the oilhole be communicated with described oil groove.
The utility model is set to further: the oil groove quantity that each casting lug thereon is provided with is 4, and the oilhole quantity that each casting lug thereon is provided with is one.
The utility model is set to further: described oil groove is kidney-shaped.
The utility model is set to further: described rotor body, casting lug thereon are made into integration by plastics.
Compared with prior art, the utility model has the advantage of, two casting lug thereons can play the effect of clamping to blade, and meanwhile, the casting lug thereon of arc and blade are conflicted, and play and rotate body and carry out auxiliary stressed effect to blade in rotation process.Be distributed in the oil groove in casting lug thereon and oilhole, can in the stable spilling of centrifugal effect, can be stable above rotor fuel-displaced, ensure the stable lubrication in chamber.Comparatively light on the rotor structure that plastics are made, heat-conducting property is poor, effectively can completely cut off the transmission of heat between blade and vacuum pump.

Embodiment
Referring to figs. 1 through Fig. 5, the rotor embodiment that the utility model is used for vacuum pump is described further.
A kind of rotor for vacuum pump, comprise columned rotor body 1, whole rotor body 1 is made of plastics, and described rotor body 1 side offers groove 11, lower seal such as groove 11 grade is on the end cap of vacuum pump, and described rotor body 1 opposite side is provided with the draw-in groove 12 with the clamping of rotating shaft clamp.Described rotor body 1 be provided with for blade axially across through hole 13, and draw-in groove 12 on vacuum pump can with the rotating shaft clamping in the external world, it is comparatively dark that groove 11 is offered, the weight of minimizing entirety that can be larger.And also offer above rotating shaft and the hole of through hole 13 to it, can directly run through rotor body 1 for blade, rotating shaft rotor driven body 1 rotates, and then can drive blade rotary, have oil circuit in vacuum pump, can to rotor fuel feeding.
Described rotor body 1 outer wall is provided with two symmetrical casting lug thereons 2, described casting lug thereon 2 is circular arc, casting lug thereon 2 leaves gap between two ends, the two ends of described through hole are corresponding with the gap between described casting lug thereon 2, when blades installation in the rotor, all can conflict with bump in blade both sides.Described casting lug thereon 2 side is provided with some oil grooves 21, lubricant oil is filled with in oil groove 21, described oil groove 21 is evenly distributed in described casting lug thereon 2, described casting lug thereon 2 opposite side is provided with the oilhole 22 be communicated with described oil groove 21, each casting lug thereon 2 is provided with an oilhole 22, oilhole 22 can guarantee the stable of rotation substantially.
Two casting lug thereons 2 can play the effect of clamping to blade, meanwhile, the casting lug thereon of arc 2 and blade are conflicted, and play and rotate body and carry out auxiliary stressed effect to blade in rotation process.Be distributed in oil groove in casting lug thereon 2 21 and oilhole 22, can in the stable spilling of centrifugal effect, can be stable above rotor fuel-displaced, ensure the stable lubrication in chamber.
Wherein, oil groove 21 quantity that each casting lug thereon 2 is provided with is 4 and described oil groove 21 is kidney-shaped, and oil groove 21 quantity that each casting lug thereon 2 is provided with is one.Four oil groove 21 structures, comparatively rationally stable, guarantee that the smectic lubricant oil in each oil groove 21 can be filled, not easily occur the situations such as leakage.Side only needs to offer an oilhole 22 and just can complete emerging of lubricant oil in addition, can guarantee the lubricating oil on another side.And the structure of kidney-shaped is comparatively reasonable, each oil groove 21 stressed comparatively stable, the power on blade can be evenly distributed on rotor, also not easily there is deformation etc. in oil groove 21.
Wherein, described rotor body 1, casting lug thereon 2 are made into integration by plastics, and comparatively light on the rotor structure that plastics are made, heat-conducting property is poor, effectively can completely cut off the transmission of heat between blade and vacuum pump.
The above is only preferred implementation of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technological schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
