Abstract
The utility model relates to a turbocharger, in particular to a compressor wheel with a three-start thread. The compressor wheel comprises a vane wheel with a connecting segment; the connecting segment is provided with a hole; a shaft sleeve connected with a vane wheel shaft is disposed in the connecting segment; the inner wall of the shaft sleeve is provided with three spiral grooves; the three spiral grooves are spirally arranged along the inner wall of the shaft sleeve to form a thread meshing with the vane wheel shaft; the three spiral grooves are evenly arranged; the angle between each two spiral grooves is 120 degrees. The compressor wheel has the advantages that the traditional single-start thread is replaced with the three-start thread, lead of the three-start thread is long, the number of rotation turns is less, speed is high, time of mounting and demounting the vane wheel is greatly shortened, time and labor are saved, labor intensity is reduced for users, and work efficiency is improved.
Description
Technical field
The utility model relates to a kind of turbosupercharger, especially relates to a kind of air compressor wheel with triple thread.
Background technique
Turbosupercharger can increase air inflow by pressurized air.It is that the exhaust energy that utilizes motor to discharge promotes the turbine in turbine chamber, and turbine drives again coaxial impeller, and the air that impeller force feed is sent here by air-strainer pipeline makes it supercharging and enters cylinder.When engine speed speeds, the waste gas velocity of discharge is also synchronizeed and is speeded with secondary speed, and impeller just compresses more air and enters cylinder, and the pressure of air and density increase the more fuel that can burn, corresponding increase fuel quantity and adjust the rotating speed of motor, increases the output power of motor with this.
Wherein the impeller in turbosupercharger adopts common single screw thread to be connected with impeller shaft, and single screw thread is because lead angle is less and it is larger to screw the frictional force of formation, and is difficult for sliding and having from trivial ability.But to slide and the not high component assembling of self-locking requirement aspect, also there is certain defect in single screw thread, because single-threaded lead angle is less, when component assembling, the stroke of at every turn tightening or dismantle away all shorter, speed is slower, required turn amount is larger, thereby can waste the more time.
Model utility content
The utility model is mainly that be connected existing required turn amount with impeller shaft by single screw thread for existing impeller larger, and the problem wasting time and energy, provides a kind of turn amount less, time saving and energy saving a kind of air compressor wheel with triple thread.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of air compressor wheel with triple thread, it comprises the impeller with linkage section, linkage section is provided with hole, in linkage section, be provided with the axle sleeve being connected with impeller shaft, the inwall of axle sleeve is provided with three spiral chutes, article three, spiral chute distributes in the shape of a spiral and forms the screw thread engaging with impeller shaft along the inwall of axle sleeve, and three spiral chutes are uniformly distributed, and the angle between adjacent spiral chute is 120 °.The utility model changes traditional single screw thread into triple thread, triple thread helical pitch is long, often revolve and turn around, the helical pitch of passing by is original single-threaded several times, thereby reduce the rotating cycle of impeller shaft, greatly shortened the time that impeller is installed and dismantled, time saving and energy saving, the labor intensity that reduces user, has improved working efficiency.Impeller adopts multiple thread to be connected with impeller shaft, and the frictional force that screws formation is less, is more conducive to transferring power and motion.
As preferably, three described spiral chutes all extend to axle sleeve bottom from the external port of axle sleeve.
As preferably, three described spiral fluted pitch scopes are 2.5～5.5mm.
As preferably, described spiral fluted groove depth is 10%～20% of axle sleeve wall thickness.
As preferably, described axle sleeve is vertical with impeller.
Therefore, the beneficial effects of the utility model are: the utility model changes traditional single screw thread into triple thread, and triple thread helical pitch is long, rotating cycle is few, speed is fast, has greatly shortened the time that impeller is installed and dismantled, time saving and energy saving, the labor intensity that reduces user, has improved working efficiency.
Accompanying drawing explanation
Accompanying drawing 1 is a kind of structural representation of the present utility model;
Accompanying drawing 2 is plan views of the utility model Intermediate shaft sleeve.
Shown in figure: 1-impeller, 2-linkage section, 3-axle sleeve, 4-spiral chute.
Embodiment
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment:
As shown in Figure of description 1, a kind of air compressor wheel with triple thread, it comprises the impeller 1 with linkage section 2, linkage section 2 is provided with hole, in linkage section 2, be provided with the axle sleeve 3 being connected with impeller shaft, axle sleeve 3 is vertical with impeller 1, the inwall of axle sleeve 3 is provided with three spiral chutes 4, article three, spiral chute 4 distributes in the shape of a spiral and forms the screw thread engaging with impeller shaft along the inwall of axle sleeve 3, as shown in Figure of description 2, article three, spiral chute 4 is uniformly distributed, angle between adjacent spiral chute 4 is 120 °, article three, spiral chute 4 all extends to axle sleeve 3 bottoms from the external port of axle sleeve 3, article three, the pitch scope of spiral chute 4 is 2.5～5.5mm, as preferred version, the pitch that the present embodiment is chosen three spiral chutes 4 is 3mm, the groove depth of spiral chute 4 is 10%～20% of axle sleeve 3 wall thickness, as preferred version, the pitch that the present embodiment is chosen three spiral chutes 4 is 15%.
This novel impeller connection part adopts the mode of triple thread to connect, when triple thread not only uses, turn amount is minimum, and the speed of tightening is faster than regular screw threads, because it is three, twisting one, enclose the distance of entering be three times of regular screw threads, thus the rotating cycle of minimizing impeller shaft, greatly shorten the time that impeller is installed and dismantled, time saving and energy saving, minimizing user's labor intensity, has improved working efficiency.Impeller adopts multiple thread to be connected with impeller shaft, and the frictional force that screws formation is less, is more conducive to transferring power and motion.
Should be understood that this embodiment is only not used in restriction scope of the present utility model for the utility model is described.In addition should be understood that those skilled in the art can make various changes or modifications the utility model after having read the content of the utility model instruction, these equivalent form of values fall within the application's appended claims limited range equally.
