Background technique
Screw compressor in the prior art is by a fixed involute scroll plate (or being quiet disk) and one in inclined
The compressor of involute motion scroll plate (or being Moving plate) the composition collapsible volume of heart convolution translation.Quiet disk is fixed on rack
On, Moving plate is driven by crankshaft (eccentric shaft) and is restricted by anti-rotation mechanism, surrounds quiet disk basic circle center, makees the plane of very little radius
Rotation.Cold media gas is sucked inside compressor by air filtering core from compressor suction duct, and then suck the formation of dynamic and static disk
In compression chamber, with the rotation of crankshaft, cold media gas sound disk bite composed by conjunction in several crescent compression chambers by by
Step is compressed into the gas of high temperature and pressure, is then continuously discharged by the axial hole of quiet disk center's component.It is former according to the reaction of stress
Reason, compressed gas can act on a gas force to sound disk, sound disk be pushed open in the axial direction, so that between Moving plate and quiet disk
Gap increases, and cold media gas is caused to leak, compressor performance decline.
Meanwhile quiet disk in the prior art is generally an integral structure, the quiet maximum position of disk stress is scroll wrap portion, and
The thickness of usual teeth portion is all thinner than the thickness of substrate, and the material that the quiet disk of this integral structure uses must be according to teeth portion intensity
Come the selection of material (because scroll wrap portion stress is maximum, and thickness is than relatively thin), thus there is substrate position intensity surplus, deposit
The waste of material the problem of (because substrate position does not need the material very good with intensity, good material general cost is all high), therefore
Existing scheme is not optimal.
