Definitions

  • Ball Mechanism with Rotary Wing belongs to mechanical engineering, or, specifically, to: theory of mechanisms, hydraulic machines, internal combustion engines.
  • a mechanism equivalent to the classical cylinder-piston mechanism (cylinder, piston, piston-rod, crankshaft), but based on a kinematic scheme which enables continual flow control or variable compression ratio, as well as minimal dimensions, and ideal balancing of masses.
  • BMRW consists of a piston in the shape of semicircle which performs rotation and oscillation in a ball-like working chamber.
  • This kinematic structure is known in the theory of mechanisms as a three-link spatial mechanism, with four axes of rotation, which, due to passive constrains (all axes intersect at one point), belongs to the class of so-called spherical mechanisms.
  • the rotary element in BMRW performs also an oscillatory motion, it is more suitable to name this element as a rotary wing, rather then piston.
  • the rotary wing divides the hemispherical housing into two chambers, the same way as the piston divides the cylinder in the case of the classical cylinder-piston design.
  • the angle of the oscillatory component of motion corresponds to the length of stroke of the pistoa
  • the mechanism is functionally equivalent to die classical cylinder-piston mechanism, but with the following advantages:
  • Figs. 1, 2 and 3 show the BMRW applied as a pump.
  • the main parts are: 1 - driving shaft; 2 - crankshaft; 3 - rotary wing; 4 - base plate with bearings 5 and 14; 5 - bearing of shaft 1; 6 - bearing of crankshaft 2; 7 - hinge between shaft 1 and rotary wing 3; 8 - hinge between rotary wing 3 and crankshaft 2; 9 - hemispherical housing; 10 - circular plate; 11 and 12 inlet and outlet openings, respectively; 13 - spherical ring; 14 - bearing which enables adjustment of angle ⁇ (rotation of housing around axis V)
  • Fig. 1 shows the appearance of the pump.
  • the mechanism for adjustment of angle ⁇ is not shown.
  • the pump is presented in the position when axis IV of hinge 7 is perpendicular to the drawing.
  • Axis I is fixed, while the position of axis II is adjustable by changing angle ⁇ .
  • Axes HI and IV rotate in space in accordance with the applied kinematic scheme. In order for this mechanism to have one degree of freedom, the following conditions have to be satisfied:
  • crankshaft 2 performs uniform rotation, three possibilities can be distinguished:
  • shaft 1 performs progressive, nonuniform rotation.
  • shaft 1 performs oscillatory motion.
  • BMRW can be realized only if the first condition is satisfied.
  • Rotary wing 3 divides the housing into two chambers, labeled in Fig. 2 as Vj and ⁇ v * 2.
  • LDP lower dead point
  • UDP upper dead point
  • Fig. 3 hinge 7 wing 3 and plate 10 are presented in a disassembled state. It can be seen that the design enables the sealing between the chambers V ⁇ and V2. in all positions of wing 3.
  • Figure 4 shows the mechanism whose kinematic structure was used to develop BMRW. All the parts in Fig. 4 have the same functions and labels as the corresponding parts in Figs. 1, 2 and 3.
  • This mechanism belongs to the class of spatial, spherical, three-link mechanisms.
  • the adjustability of parameter ⁇ is enabled by the semiarc-shaped bearing 6.
  • one cycle is as follows: When the mechanism is in LDP, the chamber V1 has minimal value, chamber V2 has maximal value, while hinge 7 covers openings 11 and 12. If the wing rotates in the direction marked in Fig. 3, slightly after LDP chambers V and V2 will be connected with openings 11 and 12, respectively. Taking into account thai from LDP to UDP chamber V1 increases while chamber V2 decreases, openings 11 and 12 have functions of inlet and outlet, respectively. When the rotary wing reaches UDP, hinge 7 covers again openings 11 and 12. After UDP connections between the chambers and openings change, V1 is connected with 12 and V2 with 11.
  • Vj decreases and V2 increases, meaning that opening 11 is still an inlet and opening 12 is an outlet.
  • the flow diagram depends on a leading shaft (1 or 2) and on angle ⁇ .
  • the flow is inherently pulsating, as is the case with all reciprocating pumps.
  • - Hinge 7 appears as a circular plate which has the same diameter as the hemisphere, and which has an exhausting orifice (19).
  • the spark plug When the wing is in LDP (presented by continuous lines in Fig 5), the spark plug performs ignition in chamber W and initiates the cycle of expansion. At the same time in chamber V occurs pre-compression. When in the vicinity of UDP orifices 19 and 15 begin to overlap, in chamber ⁇ J ⁇ begins gas exhaustion. Before the exhaustion ends, the wing, which is in the position indicated by dotted lines, enables the overflow of pre-compressed gas through overflow valve 18 from chamber V2 into working chamber V1. After this, up to LDP, the gas enters chamber V2 through one-way valve 17, while, at the same time, the cycle of compression takes place in chamber V ⁇ . After LDP the same cyclic process repeats.
  • the compression ratio can be adjusted by changing angle ⁇ , similarly to the change of discharge in the case of pump with variable flow.
  • BMRW can be used for construction of new types of pumps, compressors, internal combustion engines, hydraulic or pneumatic motors and any other devices that can use the piston-cylinder principle. Its use is especially advantageous in applications where minimal dimensions, variable flow or compression ratio and almost ideal mass balancing are sought.

Abstract

L'invention concerne un mécanisme sphérique à ailette rotative (BMRW) équivalent, du point de vue fonctionnel, au mécanisme classique cylinre-piston, mais présentant une structure cinématique différente. Le BMRW possède une chambre (10) sphérique et une ailette rotative (3) semi-ciculaire et sa conception cinématique appartient à la classe des mécanismes à trois liaisons, tridimensionnels, sphériques. La pompe sphérique à ailette rotative (BPRW) et le moteur sphérique à ailette rotative (BERW) constituent deux principaux champs d'application. Toutefois, le BMRW peut remplacer tout type de mécanisme à mouvement alternatif, s'il importe de faire usage de ses pricipaux avantages: dimensions minimales, régulation de débit et rapport de compression variables, ainsi qu'équilibrage des masses presque idéal.
