Problems solved by technology
[0003] (1) The processing technology is complicated. The processing of the positioning stop must be processed by combining the upper box or the upper half flange with the lower box. The processing of the positioning pin hole must be processed with the volute and the box.
[0004] (2) The assembly accuracy is low, the installation and centering of the volute is guaranteed by processing, and the centering of the axis of the volute and the axis of the rotor cannot be adjusted during assembly
[0005] (3) For superchargers with high medium pressure or compressors with toxic and harmful gases, it is not conducive to the design of sealing and isolation gas or balance gas interface

Disclosed are a component connector, a volute and a gear box connection mechanism and method, and a compressor, belonging to the technical field of compressors. The connector includes a first assembly, a second assembly, and an intermediate piece. The first assembly is fixedly connected to the first body to be connected, the second assembly is fixedly connected to the second body to be connected, and the intermediate piece can be detachably connected to the first body at the same time. A body to be connected, and, a second body to be connected. The connecting mechanism includes the connecting piece, the connecting half flange, and the connecting arm. The connecting half flange is fixedly connected to the volute through the connecting arm. The first component is fixedly connected to the connecting half flange, and the second component is fixedly connected to the gear box. The double-ended stud can connect the first component and the second component together, so that the volute and the gearbox can be connected together. The method is implemented based on this mechanism. The compressor includes a volute, a gear box, and the mechanism. The processing technology of the parts is simple and the assembly precision is high, so that the arrangement of the isolation gas or balance gas interface of the shaft end seal of the compressor is more reasonable.
Description
technical field [0001] The invention relates to the technical field of compressors, in particular to a modular connector, a connection mechanism and method for a volute and a gear box, and a compressor. Background technique [0002] The volute is a key component of the assembled centrifugal compressor, and its function is to convert the dynamic pressure of the gas at the outlet of the impeller or diffuser into static pressure. The impeller of the assembled compressor is in the form of a cantilever, and each impeller is provided with a volute matching its basic stage, and the volute is connected with the gear box. The existing connection structure is as follows: the volute and the gear box are connected by bolts in the way of positioning notches or positioning pins. This connection method has the following disadvantages: [0003] (1) The processing technology is complicated. The processing of the positioning spigot must process the upper box body or the upper half flange an...
