example 1

[0050] Example 1: if Figure 1 to Figure 15 As shown, a laminated screw shaft is disclosed. The screw shaft includes a sheet part 1 and a shaft 2. The sheet part 1 has a tooth bottom engaging part 7 and a tooth top engaging part 8 on the outside, and the sheet part 1 has a shaft hole , there is at least one tooth-shaped protrusion in the shaft hole, and at least one helical groove on the outside of shaft 2, the number of tooth-shaped protrusions in the shaft hole of thin-film part 1 and the number of outer helical grooves in shaft 2 The same, and cooperate with each other, the outside of the shaft 2 is tightly and orderly covered with multiple thin-film parts 1, the relative position between the shaft 2 and the multi-chip thin parts 1 is fixed, and the mutual gap between the shaft 2 and the multi-chip thin parts 1 It is filled with metal and adopts the following processing steps:

[0051] Step 1): the sheet metal is machined into a toothed sheet part 1;

[0052] Step 2): The...

Abstract

The invention relates to a laminated screw shaft, in particular to a screw shaft, and solves the problems that when a screw shaft is machined in the prior art, the process is complex, the machining time is long, the machining difficulty is large, and the machining cost is high. The screw shaft is formed by overlapping a plurality of toothed sheet parts after the toothed sheet parts are arranged on shafts in a sleeving manner, and clearances are filled with molten metal in the quenching process. The screw shaft comprises the sheet parts and the shafts. Tooth bottom meshing portions and tooth top meshing portions are arranged on the outer portions of the sheet parts, shaft holes are formed in the sheet parts, and at least one tooth-shaped protrusion is arranged in each shaft hole. At least one spiral groove is formed in the outer portion of each shaft, the number of the tooth-shaped protrusions in the shaft holes of the sheet parts is equal to that of the spiral grooves outside the shafts, and the tooth-shaped protrusions match the spiral grooves. The outer portions of the shafts are closely sleeved with the sheet parts in order, the relative positions between the shafts and the sheet parts are fixed, and the clearances between the shafts and the sheet parts are filled with metal. The technical aim of fast manufacturing the high-physical-property screw shaft with low cost is achieved.

Description

technical field [0001] The invention relates to a laminated screw shaft, in particular to a screw shaft which is formed by inserting a plurality of thin sheet parts with teeth 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 realize unattended...
