Description
Technical field
This utility model relates to the left-handed female screw axle that a kind of interior multiple-grooved metal-to-metal adhesive adhesion coating is filled, particularly relate to a kind of be inserted in axle by the toothed sheet parts of multi-disc after step up after superposition and the screw shaft of impregnation after quenching.
Background technology
Helical-lobe compressor, also referred to as screw compressor, including screw air compressor and screw rod technique compressor (vinyl chloride compressor etc.), helical-lobe compressor is divided into single screw compressor and double-screw compressor, and helical-lobe compressor is to utilize screw shaft shape rotor to compress do gyration and pumped (conveying) medium in cylinder body.
Helical-lobe compressor has reliability height, and parts are few, it does not have consumable accessory, thus its operating is reliable, and the life-span is long, and general screw machine host header reaches 30 years projected life; Convenient operating maintenance, automaticity is high, and operator need not move through long-time professional training, it is achieved unmanned operates; Dynamic equilibrium is good, it does not have unbalance inertia force, and machine can smoothly high speed operation, it is achieved foundation-free operates; Strong adaptability, has the advantages that to force gas transmission, and volume flow is little affected by the impact of pressure at expulsion, higher efficiency can be kept in broad condition range, when compressor arrangement without any changes, it is adaptable to various working, thus be prone to sizing batch production; Multi-phase mixed delivering, actually leaves gap between the rotor flank of tooth, thus resistant to hydraulic shock, can the force feed gas containing liquid, containing dusty gas, easy polymerizable gas etc.; Guiding valve Flow-rate adjustment, it is not necessary to return stream, it is possible to effectively reduce the advantages such as energy consumption, therefore, helical-lobe compressor is widely used.
The subject matter of containment helical-lobe compressor development is the cost height of helical-lobe compressor at present, owing to the flank of tooth of the screw shaft rotor of screw machine is a space curved surface, the outer contour in its cross section is to be formed by connecting by the curve of multiple complexity, the curved surface of the flank of tooth of overall screw shaft rotor is formed through spiral stretch by the outline of above-mentioned complex curve, the flank of tooth of screw shaft rotor is the curved surface of a complicated stereoscopic three-dimensional, therefore, turning common in machining and milling device are not competent, numerical control turning general at present and milling device can not be processed, machining needs utilize special cutter to be processed on expensive special equipment.
The processing of screw shaft rotor, divides from product material, is generally divided into foundry goods machining and forged steel pieces machining.
The screw shaft rotor that foundry goods machining shapes, it is necessary to first cast form, then with machining center and dedicated tool machining, the quality such as the rigid of product, wearability is weaker relative to the screw shaft rotor that forged steel pieces cuts.
During the screw shaft rotor machining that forged steel pieces cuts, must first by steel formed by forging, then with machining center and dedicated tool repeatedly machining, Quenching Treatment and Surface Finishing is carried out again after shaping, therefore, technological requirement is high, technological process is complicated, process velocity is slow, production cost is high.
