采用“直线包络螺杆副”作单螺杆压缩机啮合副型线可以获得稳定的流体动力润滑,但此种啮合副加工困难。本文提出采用“圆台二次包络啮合副”作为单螺杆压缩机啮合副的型线。实践表明,这种啮合副加工便利,适于大批量生产,并且同样能获得稳定的流体动力润滑,进一步提高压缩机运行可靠性。本文详细阐述了“圆台二次包络啮合副”的数学模型、齿面性质、结构特征、加工方法,并用实验加以验证。 The use of a “linear envelope screw pair” as a single-screw compressor meshing with a secondary line produces a stable hydrodynamic lubrication, but such mating process is difficult. This paper proposes the use of “round table secondary enveloping meshing deputy” as a single screw compressor meshing vice profile. Practice shows that this mating mesh processing convenience, suitable for mass production, and can also get a stable hydrodynamic lubrication, to further improve compressor reliability. This paper elaborates the mathematical model, the nature of the tooth flanks, the structure characteristics and the processing method of “the secondary enveloping meshing of the circular table” and verifies it by experiments.
