Abstract
The utility model provides a novel blade structure of a TDI motor vacuum pump, which comprises rotary vane heads, a rotary vane body, a main shaft, a pump casing body and a fixed seat, wherein the pump casing body is mounted on the fixed base, fixing holes are formed in the peripheries of the pump casing body and the fixed seat, a casing outer edge is arranged on the outer side of the pump casing body, a pump chamber is formed in the casing outer edge, a shaft hole is formed in the middle of the pump chamber, the main shaft is mounted inside the shaft hole, the main shaft comprises a shaft head and a shaft handle which are integrally formed, a main shaft oil groove is formed inside the shaft head, the rotary vane body is mounted inside the main shaft oil groove and the rotary vane heads are arranged at the two ends of the rotary vane body. In the novel blade structure, the novel rotary vane heads adopt rolling friction so as to enable the abrasion to be lowered greatly, the hollow structure of a novel rotary vane enables motor oil to enter the interior of the rotary vane so as to lower the temperature of the rotary vane inside, a rotary vane lubrication circuit does not change an original pump body structure, so that an original pump body pressure casting die can still be used, and further the cost is lowered.
Description
Technical field
The utility model relates to vacuum pump technology field, is specially a kind of novel vane structure of TDI motor vacuum pump.
Background technique
Vacuum pump is a kind of rotating volume-varying gas transfer pump, vacuum pump must have fore pump to coordinate to use and in wider pressure range, have larger pumping speed, in gas, contained dust and water vapor is insensitive to extracting, be widely used in the industries such as metallurgy, chemical industry, food, electronics plated film.
Vacuum pump comprises dry screw vacuum pump, water ring pump, reciprocating pump, slide valve pump, sliding vane rotary pump, Roots pump and diffusion pump etc., and these pumps are requisite main force pump kinds in Chinese national economy every profession and trade application vacuum technology process.In recent years, being accompanied by China's economy grows continuously and fast, the relevant downstream application industry of vacuum pump keeps the rapid growth impetus, and simultaneously in vacuum pump application field constantly under jointly the pulling of the factor such as expansions, China's vacuum pump industry has realized sustainedly and stably and having developed fast.
Along with the development of vehicle vacuum pump, conventional Vacuum pump rotary vane structure makes blade head when rotated and between the pump housing, produces sliding friction, accelerate the wearing and tearing of blade head, therefore usually adopt the material of high-performance price to cook blade head, this has also impelled a kind of birth of Novel rotary chip architecture vacuum pump.
Model utility content
The technical problem that the utility model solves is to provide a kind of novel vane structure of TDI motor vacuum pump, to solve the problem proposing in above-mentioned background technology.
The technical problem that the utility model solves realizes by the following technical solutions: a kind of novel vane structure of TDI motor vacuum pump, comprise: blade head, rotary vane, main shaft, pump case housing, fixed base, described pump case housing is arranged on fixed base, pump case housing, fixed base surrounding is provided with fixed hole, pump case hull outside is provided with housing outer, housing outer forms pump chamber, pump chamber middle part is provided with axis hole, main shaft is installed in axis hole, described main shaft comprises spindle nose, footstalk, spindle nose, footstalk is one-body molded, in spindle nose, offer main shaft oil groove, in main shaft oil groove, rotary vane is installed, rotary vane two ends are provided with blade head.

Compared with prior art, the beneficial effects of the utility model are: in the utility model, Novel rotary head utilize rolling friction that wearing and tearing are reduced greatly, the hollow structure of novel blade makes engine motor oil enter blade inside, lower the temperature from inner blade, and in the utility model, blade lubricating oil path makes original pump housing die casting grinding tool still can continue to use to former pump body structure without change, further reduces costs.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is rotary vane structural representation of the present utility model.
Fig. 3 is main shaft structure schematic diagram of the present utility model.
Embodiment
In order to make of the present utility modelly to realize technological means, creation characteristic, reach object and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
As shown in Figures 1 to 3, a kind of novel vane structure of TDI motor vacuum pump, comprise: blade head 1, rotary vane 2, main shaft 3, pump case housing 4, fixed base 8, described pump case housing 4 is arranged on fixed base 8, pump case housing 4, fixed base 8 surroundings are provided with fixed hole 9, pump case housing 4 outsides are provided with housing outer 11, housing outer 11 forms pump chamber 10, pump chamber 10 middle parts are provided with axis hole, main shaft 3 is installed in axis hole, described main shaft 3 comprises spindle nose 12, footstalk 13, spindle nose 12, footstalk 13 is one-body molded, in spindle nose 12, offer main shaft oil groove 7, rotary vane 2 is installed in main shaft oil groove 7, rotary vane 2 two ends are provided with blade head 1.
Described rotary vane 2 two ends are provided with groove 6, and groove 6 is arc-shaped structure, and blade head 11 is arranged in the groove 6 at rotary vane 2 two ends.
Described rotary vane 2 both sides are provided with filler opening 5, and filler opening 5 is ellipsoidal structure.
While installing and using, blade in Fig. 1 is put in main shaft opening slot, rotary vane filler opening 5 in Fig. 2 is aimed to the main shaft oil groove 7 in Fig. 3, again blade head is put into how much die cavities that rotary vane two groove 6 and pump case surround, added that pump case end cap tightens fixing bolt and be in place and can use.
When work, utilize original main shaft to drive blade rotation by direct-connected mode, the engine motor oil that blade provides by main shaft oilhole is lubricated and self cooling blade head, adopts the rotary vane of hollow in the utility model, can well ensure the lubricity of blade head and self is cooling.
In the utility model, Novel rotary head utilize rolling friction that wearing and tearing are reduced greatly, therefore make the blade head with PEEK material originally use ABS material cheaply instead, make cost.The hollow structure of novel blade makes engine motor oil enter blade inside, lowers the temperature from inner blade.Novel blade lubricating oil path makes original pump housing die casting grinding tool still can continue to use to former pump body structure without change, further reduces costs.
More than show and described basic principle of the present utility model and major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and specification, describes just illustrates principle of the present utility model; do not departing under the prerequisite of the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.Claimed scope of the present utility model is defined by appending claims and equivalent thereof.
