New description: [New technical field] This creative department is related to the technical field of optoelectronics industry or semiconductor industry. The thirsty wheel vacuum pump is especially suitable for the rotor body of the cave vacuum pump. One-piece type rotor with one pjec sentence. Slave [Prior Art] In the manufacturing process of optoelectronic products and semiconductor products, different etch procedures, chemical vapor deposition and physical vapor deposition are often used. (4) The process flow must generally be carried out in an isolated vacuum processing chamber. The current vacuum processing chamber is generally operated by a turbine that sucks. The boring body...the structural design of the existing difficult vacuum pump, Basically consisting of: a substantially circular outer casing, a base provided at the bottom of the outer casing, a cymbal; a female body in the base and a rotor assembly in the outer casing and driven by a motor; the rotor The component structure is generally as shown in the fifth and sixth figures. The subassembly (90) includes: a mandrel (8) that can be coupled to the motor, and is fixedly coupled to the end of the multi-layered leaf. Room: a magnetic ring (93) that is closely related to the 叮°, and a cover ring (94) of the multi-layer impeller (92), and a member of the gentleman (95); The multi-layer impeller (92) of the mandrel (91) of the mandrel (91) is composed of a plurality of impeller units (92 〇) which are sequentially stacked and two solids. The impeller units (92 〇) are supplied to the shaft center. (91) The passing shaft hole (921), on the outer circumference, 'U a plurality of blades surround the formed vane set (922)' and the respective impeller unit (920) abuts the shaft hole (921) on the top side of the 3 M356017 And a bottom side portion, correspondingly provided with a convex ring (923) and a groove (924) which can be matched with each other, thereby increasing the groove (924) of each impeller unit (920) by heating. In the order of stacking and fitting, after cooling, a plurality of impeller units (920) can be stacked and assembled into a multi-layer impeller (92) as shown in the figure, and the aforementioned mandrel (9彳) is also utilized. The multi-layer impeller (92) is heated and then placed in the shaft hole (921) to be cooled to form a tight fit, and the assembly is coupled to the axial center position of the multilayer impeller (92). In the prior art, a multi-layered impeller (92) structure in which a plurality of impeller units (92 〇) are stacked and assembled, and an assembly structure of a multi-layer impeller (92) and a mandrel (91) are used. Problem: 1. The assembly operation of stacking a plurality of impeller units (920) in sequence and combining the multi-layer impeller (92) with the mandrel (91) not only requires considerable labor and time, but also considerable labor costs. At the time, it is necessary to use expensive special tools such as heating equipment and freezing equipment, and the manufacturing cost of the rotor assembly (9〇) is high enough to meet the industrial utilization demand. • 2. Because the mandrel (91) and the multi-layer impeller (92) and the multi-layer impeller (92 several impeller units (920) are assembled in a fitting fit by (91) and each impeller unit (92〇) There is inevitably some gap or error between the rotor assembly (90), it is difficult to obtain a good dynamic balance effect, easy to smooth the operation of the shadow-wheel vacuum pump and the operating efficiency. 3. Existing assembly in the multi-layer impeller (92) suction side slot The multiples of the room (93 mountain) and the fastening ring for the magnetic cylinder (95) are also closely related to the problem of assembly trouble and high cost. In order to solve the problem of the combination of the existing turbo vacuum pump, the high processing cost, and the difficulty in obtaining the shortage and limitation, the present invention provides a single-type rotor with a structural fine turbo vacuum pump. The main purpose of this creation is to use structural integration and sigh of the sub-body. The 5+ assembly includes a rim portion, a shaft column portion and a one-piece integrated structure, which not only can effectively solve various assembly and processing problems, but also enables the single rotor to achieve optimum conversion efficiency.
