Efficient screw rotor
The third-generation U Series Host
1, independent research and development and production of the third generation of U-series mainframe, using a new tooth that is double helix host male and female rotor gear ratio of 5:6 to form the tooth profile parameter equation arc, arc envelope, put lines, dots, ellipses optimal combination of programs, the adjacent two teeth formed at the connection point a fine curve tangent slope transition 0.02mm-0.035mm to obtain high-precision and uniform tooth profile of the working gap space.
2, composed of two adjacent teeth tooth curve smooth transition at the connection point, the rotor contact line is short, triangular small leak, flow area, was streamlined, aerodynamic resistance, lower than the power, you can get a higher power. Larger interdental area utilization factor, make full use of the rotor teeth volume, long-necked than small, and enhance the rigidity of the rotor, streamlined design increases the intake and exhaust flow area orifice amount greater trochanter low speed, low noise and longer life.
3, the use of imported high-quality carbon steel, quenched, material has good microstructure and mechanical properties of the tooth surface hardness. Reach HB200-240, good abrasion resistance, spiral tooth surface using an efficient semi-finishing milling rotor in Japan after precision grinding, along the spiral male rotor and female rotor pitch helical gear together with a zero-for-zero-touch high-voltage work side space conjugation generating method grinding. Body is made of multi-axis machining centers batch processing, combined with top-level high-precision coordinate detection equipment, access to the most sophisticated smooth space backlash.
4, the host is using the best combination of imported bearings, precision bearings paired four penalty short cylindrical bearing positioning, effectively ensuring the rotor during operation, axial, radial high-precision positioning; bearing lubrication circulating oil lubrication, and through cycle oil away heat generated by the movement, high-strength load-bearing design to withstand the load pressure of 17bar wider range of applications.
5, the unique design allows the oil is injected into the channel constant cooling lubricants play a role.
6, according to the Chinese Academy of Science and Technology issued Novelty display, independent intellectual property rights of the host product can achieve high efficiency energy saving, more innovation, integrated technology reached the international advanced level. |
