Abstract
The utility model relates to a board -like displacement pump is revolved to two -stage, include casing, transmission shaft, revolve board, stator, the stator install on the casing, the transmission shaft setting is inside the stator, symmetrical arrangement has a soon board on the transmission shaft, the molded lines of stator inner chamber do: be 53 at angle A~127 o'clock for one section circular arc of R=15.175mm, is 233 at angle A~for one section circular arc of R=22.225mm at 307 o'clock, is R=17mm+3.525cos [ 180 (A -37) / 106 ] mm's outer equidistant curve between two sections circular arcs. The utility model discloses through using the identification, the molded lines of stator has higher oil extraction and oil absorption little with the blade fit clearance.
Description
Technical field
The utility model 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 purpose of this utility model is to provide a kind of two-stage spiral plate type displacement pump, and 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.
The technical solution of the utility model 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 utility model 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 utility model proves through using, and the molded line of stator, little with blade matching gap, has higher oil extraction and oil absorption.
