Abstract:
A one-stage transmissible turbocharger comprising:a front current-guider having a front intake hole defined by an annular wall, three ribs formed between said annular wall of said intake hole and a bearing base of a turbine wheel, said bearing base having an inner bearing groove for receiving a ball bearing and a shaft seal therein, an inner annular wall of said front current-guider forming an air passageway by combining with a front wall surface of a rear current-guider, said turbine wheel having at least a plurality of leaves helically formed on a surface; each leaf of said turbine wheel having five continual sections, any group of four neighboring leaves forming an anti-backwash layer, an angle for catching in air changed to 32 degrees from the conventional 45 degrees for catch inlet section, of said leaf; said turbine wheel located in said inner wall of said front current-guider, having a center shaft hole with a key groove for a shaft to fit therein and fixed firmly with a long key fitting in said key groove, said shaft rotating said turbine wheel, said shaft further having male threads respectively formed in a front and a rear section, said turbine wheel fixed with said shaft by means of said front male threads engaging with a nut and a washer; a current guiding disc provided behind said turbine wheel, having a curved guiding surface on a right side, a center shaft hole for said shaft to pass through, a plurality of threaded holes formed around said center shaft hole for bolts to screw said current guiding disc with a rear current-guider, said shaft received in two ball bearings and a shaft seal after passing through said current guiding disc, said two ball bearings deposited in a shaft hole of said rear current-guider with said shaft passing through said shaft hole and through a shaft ring to be fixed with a pinion thereon by means of a key fitted in a key groove of said pinion to combine said pinion with said shaft, said shaft and said turbine wheel rotated by said pinion, said rear male threads of said shaft fitted around with a washer, then screwing with a nut and fitted around with a ball bearing deposited in a small shaft hole of a rear cover; said rear current-guider having a plurality of front threaded holes for bolts to combine said rear current-guider with said front current-guider, said rear current-guider having a plurality of rear threaded holes for bolts to combine said rear current-guider with said rear cover, said rear current-guider having an air passageway as an air outlet for augmented air pressure to be guided to an intake of a carburetor of an engine, said rear-current-guider having a bearing groove for a ball bearing to fit therein; a transmitting shaft passing through said ball bearing for a large gear fixed thereon, said large gear engaging with said pinion, said large gear and said pinion contained in an lubricating oil chamber formed in said rear current-guider, said large gear having two one-way bearings fitted in a center hole, a shaft sleeve fitted between said two ball bearings, said shaft sleeve having an inner shaft sleeve fixed firmly with said transmitting shaft with a key, said inner shaft sleeve having a plurality of ratchet teeth spaced apart on an outer surface, each said ratchet tooth having a spring groove in an inner side for receiving a buffer spring therein, each said buffer spring having a top block to contact resiliently with a round post deposited in a hole of said shaft sleeve, said transmitting shaft having its right side fitted with two ball bearings and a shaft seal, said two bearings and said shaft seal deposited in a large shaft hole of said rear cover; a belt wheel having a bush fixed in its center hole, said bush having a shaft hole and key grooves formed in an inner and outer side of said shaft hole for keys to fit therein so as to indirectly combine said belt wheel firmly with said transmitting shaft to rotate together, said sleeve of said belt wheel having a large diameter portion and a small diameter portion, said large diameter portion having a plurality of curved spring holes spaced part near its outer edge for a plurality of buffer springs to fit therein, an annular left cover closing a left side of said large diameter portion and having a plurality of slots spaced apart and corresponding to said spring holes of said large diameter portion, a plurality of T-shaped nuts fitting in said slots of said left cover and into a large section of each said spring hole of said large diameter portion, an annular right cover closing a right side of said large diameter portion and having a plurality of round holes and contacting a left side of said belt wheel; said belt wheel having an inner sleeve fitted in its center hole, said inner sleeve fitting around said small diameter portion of said bush, said belt wheel further having a plurality of threaded holes spaced apart in a left side surface and extending to a right side surface for a plurality of bolts to fit through to engage with said T-shaped nuts to combine said bush and said belt wheel with said transmitting shaft.
