example 1

[0050] Example 1: if Figure 1 to Figure 15 As shown, a disclosed laminated screw compressor includes a cylinder, and there is a screw shaft in the cylinder. The screw shaft is a laminated screw shaft, and the screw shaft also includes a sheet part 1, a shaft 2, and a sheet part 1 There are gear bottom meshing parts 7 and tooth top meshing parts 8 on the outside, and there is a shaft hole in the sheet part 1, and there is at least one tooth-shaped protrusion in the shaft hole, and there is at least one spiral groove on the outside of the shaft 2, and the sheet part 1 The number of the tooth-shaped protrusions in the shaft hole is the same as the number of the external spiral grooves of the shaft 2, and they cooperate with each other. The outside of the shaft 2 is closely and orderly covered with a plurality of sheet parts 1, shaft 2 and a plurality of sheets The relative position between the parts 1 is fixed, the gap between the shaft 2 and the multi-piece thin parts 1 is fil...

example 2

[0061] Example 2: if Figure 1 to Figure 15 As shown in Example 1, a disclosed laminated screw compressor adopts one of the methods of stamping, wire cutting, laser cutting, plasma cutting, and high-pressure liquid force cutting to process metal sheets into toothed sheet parts 1 .

example 3

[0062] Example 3: if Figure 1 to Figure 15 As shown in Example 1, a disclosed laminated screw compressor is quenched by high frequency quenching, intermediate frequency quenching or heating and quenching in a heat treatment furnace.

Abstract

The invention provides a stacked screw rod type compressor and particularly relates to a compressor for a screw rod shaft. The screw rod shaft is formed in the mode that a plurality of sheet parts with teeth are arranged on the shaft in a sleeving mode and then stacked, and gaps are filled with metal solutions during quenching. The compressor aims to overcome the technical defects that when a compressor in the prior art is used for machining a screw rod shaft, the technology is complex, machining time is long, machining difficulty is large and machining cost is high. The screw rod shaft comprises a screw rod shaft body, and the screw rod shaft body is formed in the mode that the sheet parts with the teeth are arranged on the shaft in the sleeving mode and then stacked. Each sheet part is at least provided with one connection hole, and the connection holes are overlapped into a through hole after the sheet parts are stacked. The connection holes are fixedly connected into the screw rod shaft body through connecting pieces. The screw rod shaft body is quenched, heated and then immersed in the metal solutions, and the screw rod shaft body is taken out from the metal solutions to be quenched and cooled. The metal solutions cool and solidify into metal, and the gaps between the sheet parts of the screw rod shaft body and the surface of the screw rod shaft body are filled with the metal. The technical purpose of quickly manufacturing the compressor with high physical performance at a low cost is achieved.

Description

technical field [0001] The invention relates to a laminated screw compressor, in particular to a compressor which adopts a screw shaft which is formed by inserting multiple toothed sheet parts into the shaft and superimposed, and the gap is filled with metal solution during quenching. Background technique [0002] Screw compressors, also known as screw compressors, include screw air compressors and screw process compressors (vinyl chloride compressors, etc.), screw compressors are divided into single-screw compressors and twin-screw compressors, screw compressors use screw The shaft-shaped rotor makes rotary motion in the cylinder to compress and transport the medium. [0003] The screw compressor has high reliability, few parts, and no wearing parts, so it operates reliably and has a long life. The design life of the main screw head of a general screw compressor is 30 years; it is easy to operate and maintain, and has a high degree of automation. Professional training to r...
