Abstract
The invention relates to a two-stage rotary plate type displacement pump. The two-stage rotary plate type displacement pump comprises a shell, a transmission shaft, rotary plates and a stator. The stator is installed on the shell. The transmission shaft is arranged in the stator. The rotary plates are symmetrically arranged on the transmission shaft. The molded line of an inner cavity of the stator comprises a segment of arc with the radius R being 15.175 mm when the angle A ranges from 53 degrees to 127 degrees, a segment of arc with the radius R being 22.225 mm when the angle A ranges from 233 degrees to 307 degrees, and an outer isometric curve with the radius R being 17 mm+3.525 cos[180(A-37)/106] mm between the two segments of arcs. It is proved through use that the fit clearance between the molded line of the stator and a vane is small, and high oil discharge and absorption capacity is achieved.
Description
Technical field
The present invention relates to a kind of displacement pump, especially a kind of two-stage spiral plate type displacement pump.
Background technique
The lubricating oil pump that aircraft drive system adopts is two-stage spiral plate type displacement pump, as shown in Figure 1, working principle forms 4 chambeies by transmission shaft, 4 rotating plates and an eccentric stator with special molded line, transmission shaft drives rotating plate to rotate, by the restriction of molded line in eccentric stator, constitute at diverse location and stator type group the cavity that volume constantly changes in rotation one week process of rotating plate, achieve pressurization and the conveying of lubricating oil.From working principle, stator is the critical component of lubricating oil pump, the molded line of stator coordinates with blade the oil extraction and oil suction that achieve pump, and the control of curve of the rotator shape to matching gap of lubricating oil pump is very important, and its matching gap has a great impact oil extraction and oil absorption.
Summary of the invention
The object of this invention is to provide a kind of two-stage spiral plate type displacement pump, the molded line of the pump stator of this displacement pump is after coordinating with blade, and matching gap is little, thus improves oil extraction and the oil absorption of spiral plate type displacement pump.
Technological scheme of the present invention is, described two-stage spiral plate type displacement pump comprises housing, transmission shaft, rotating plate, stator, described stator is arranged on housing, transmission shaft is arranged on stator interior, transmission shaft has been arranged symmetrically with rotating plate, described rotating plate is along the radial arrangement of transmission shaft, and can contact with bore of stator after radial motion under the influence of centrifugal force, the molded line of described bore of stator is: the one section of circular arc when angle A is 53 ° ~ 127 ° being R=15.175mm, it is one section of circular arc of R=22.225mm when angle A is 233 ° ~ 307 °, it is the outer equidistant curve of R=17mm+3.525cos [180 (A-37)/106] mm between two sections of circular arcs.
The bore of stator molded line of the present invention's design, proves through over-fitting and l-G simulation test, adopts the curve of the rotator shape of the method design more smooth, continuous, and meets the characteristics of motion of rotating plate, can realize this displacement pump traffic ability requirement.The present invention proves through using, and the molded line of stator, little with blade matching gap, has higher oil extraction and oil absorption.
