example 1

[0050] Example 1: if Figure 1 to Figure 15 As shown, a disclosed multi-piece superimposed sintered screw compressor includes a cylinder, and there is a screw shaft in the cylinder. The screw shaft is a multi-piece superimposed sintered screw shaft, and the screw shaft also includes thin slice parts 1, The shaft 2, the outer part of the sheet part 1 has tooth bottom meshing part 7 and tooth top meshing part 8, the thin part 1 has a shaft hole, and there is at least one protruding tooth in the shaft hole, and the outside of the shaft 2 has at least one helical tooth The number of grooves, the number of tooth-shaped protrusions in the shaft hole of the sheet part 1 is the same as the number of the external spiral grooves of the shaft 2, and they cooperate with each other. The relative position between the shaft 2 and the multi-piece thin parts 1 is fixed, the mutual gap between the shaft 2 and the multi-piece thin parts 1 is filled with metal, and the screw shaft in the cylinder...

example 2

[0061] Example 2: if Figure 1 to Figure 15 As shown in Example 1, a disclosed multi-piece superimposed sintered screw compressor adopts one of the methods of stamping, wire cutting, laser cutting, plasma cutting, and high-pressure liquid force cutting to process the metal plate into a toothed Sheet parts1.

example 3

[0062] Example 3: if Figure 1 to Figure 15 And shown in example 1, the compressor of a kind of sintered screw that discloses a kind of stacked multi-sheet, the metal powder that flux is coated with outside is selected from following any one or the mixing of two or more in arbitrary proportions: lead powder, tin powder, Copper powder, aluminum powder.

Abstract

The invention relates to a multiple slices-superimposed sintering screw compressor, and especially relates to a compressor of a sintering screw formed through superimposing a plurality of quenched toothed slice parts sleeved outside shafts. A screw shaft is provided to solve the technical defects of complex process, long processing time, large processing difficulty and high processing cost in the screw shaft processing process of compressors in the prior art. The screw shaft comprises a screw shaft body, the screw shaft body is formed through mutually superimposing the quenched toothed slice parts sleeved outside shafts, spaces among the slice parts and the surfaces of the slice parts are filled with metal powder, each of the slice parts is provided with at least one connecting hole, connecting holes are overlapped after the superimposing of the slice parts in order to form a through hole, the connecting holes are fixedly connected through a connecting piece to form the screw shaft body, and the metal powder solidifies to form metal after the screw shaft body is sintered and cooled, and is filled in the spaces among all the slice parts of the screw shaft body and the surface of the screw shaft body, so the technical purpose of cheap and rapid manufacturing of the compressor with high performances is achieved.

Description

technical field [0001] The invention relates to a compressor with a multi-layer superimposed sintered screw, in particular to a compressor using a multi-piece quenched toothed sheet part inserted into a shaft and then superimposed on a sintered screw. 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 realize unattended operation; good ...
