发明名称 Gear pump with spline function generated gear profile
摘要 <p>A rotary positive-displacement pump comprises two gear wheels which mesh with each other without encapsulation. Each gear wheel has a plurality of teeth with a profile which falls within a band of tolerance of +/- 1/20th of the depth of the tooth with respect to a theoretical profile similar to a profile defined by a natural spline function passing through a plurality of nodal points having pre-established coordinates äX, Yü. <IMAGE></p>
