摘要： A cross section of a tooth profile of a first screw rotor (17) perpendicular to the rotor axis includes a tooth top arc (A1B1), a tooth bottom arc (C1D1), a first curve (A1C1), and a second curve (B1D1). The first curve (A1C1) is a first trochoidal curve that connects a first end (A1) of the tooth top arc (A1B1) to a second end (C1) of the tooth bottom arc (C1D1). The second curve (B1D1) connects the second end (B1) of the tooth top arc (A1B1) to the first end (D1) of the tooth bottom arc (C1D1). The second curve (B1D1) is a composite curve formed by an involute curve (B1E1) and a second trochoidal curve (E1D1), which extend continuously from each other at a first intersection point (E1). A screw pump (11) thus suppresses leakage of fluid with improved performance.
摘要翻译：垂直于转子轴线的第一螺杆转子（17）的齿廓的横截面包括齿顶弧（A1B1），齿底弧（C1D1），第一曲线（A1C1）和第二曲线（B1D1 ）。第一曲线（A1C1）是将齿顶弧（A1B1）的第一端（A1）与齿底弧（C1D1）的第二端（C1）连接的第一次摆线曲线。第二曲线（B1D1）将齿顶弧（A1B1）的第二端（B1）与齿底弧（C1D1）的第一端（D1）连接。第二曲线（B1D1）是通过在第一交点（E1）处彼此连续延伸的渐开线曲线（B1E1）和第二次摆线曲线（E1D1）形成的复合曲线。因此，螺杆泵（11）能够以改进的性能来抑制流体泄漏。

摘要： A housing of a Roots pump is configured by joining a lower housing member and an upper housing member that are separable from each other. With the upper and lower housing members joined together, an upper accommodating portion and a lower accommodating portion form a front bearing accommodating portion and a rear bearing accommodating portion, which accommodate whole bearings, respectively. The Roots pump further includes bearing holders attached to the bearings and fixed to the lower housing member so that the bearings are received in the lower accommodating portion in a positioned state.

摘要： A housing (2) of a Roots pump (1) supports a drive shaft (3) and a driven shaft (4) with radial bearings (32, 33) so as to be rotatable. The housing (2) is formed by joining an upper housing member (20) to a lower housing member (10). The lower housing member (10) has lower bearing support portions (13), and the upper housing member (20) has upper bearing support portions (23). Opening edges (13a) of each lower bearing support portion (13) are positioned above the centers (P1) of the bearings (32, 33). An opening width (T1) of each lower bearing support portion (13) is smaller than the diameter (D1) of the bearings (32, 33). This structure suppresses the bearings (32, 33) from being separated from the lower housing member (10) during an assembling operation of the fluid machine.
摘要翻译：罗茨泵（1）的壳体（2）通过径向轴承（32,33）支撑驱动轴（3）和从动轴（4）以便可旋转。壳体（2）通过将上部壳体构件（20）连接到下部壳体构件（10）而形成。下壳体部件10具有下轴承支撑部13，上壳体部件20具有上轴承支撑部23。每个下轴承支撑部分（13）的开口边缘（13a）位于轴承（32,33）的中心（P1）上方。每个下轴承支撑部分（13）的开口宽度（T1）小于轴承（32,33）的直径（D1）。该结构在流体机械的组装操作期间抑制轴承（32,33）与下壳体构件（10）分离。
