However, pits, grooves and holes for installing gas sealing elements and engine oil sealing elements are machined on two end faces and top corners of the existing triangular rotor, the heat dissipation is required to be good, the wall thickness cannot be too thick, and when the triangular rotor and the phase internal gear are combined together in a welding mode, the parts are easy to deform.
2. In order to reduce abrasion and improve sealing performance, the dimensional accuracy requirements of the rotor profile and the cylinder profile are high. Because pits, grooves and holes are arranged on two end faces and a vertex angle of the triangular rotor, the wall thickness on a rotor profile line is uneven, the wall thickness at partial positions is very thin, and deformation is easy to generate during welding.
3. In order to ensure the performance and reliability of the product, the triangular rotor and the phase internal gear are made of two different materials. Because the thermal expansion coefficients of the two metals are different, larger stress and deformation can be generated during welding; in addition, the original phase internal gear has a complex structure, so that the gear grinding cannot be performed, and the gear precision is low and can only reach 9-level precision.
