Definitions

  • the invention relates to a rotary machine core assembly and to a rotary machine comprising the rotary machine core assembly.
  • the endplates of a rotary engine are held in place against the sides of the engine rotor housing using a through bolt or threaded stud located through each endplate and extending through the rotor housing.
  • the rotor housing is made of Aluminium and the through bolts are typically made of steel alloy.
  • the rotor housing defines a trochoid bore within which the engine rotor rotates during operation. When the engine is running there is a thermal distribution around the circumference of the rotor housing trochoid bore, a cooler region existing around the area of engine induction and a hotter region being associated with the ignition and power phase of the engine cycle.
  • the regions of the trochoid which become hotter have either engine cooling fins or a liquid coolant passageway provided within the rotor housing to assist with cooling.
  • a general, measurable distortion of the rotor housing caused by the heat generated during operation.
  • a surface coating, such as nickel silicone is applied to the aluminium surface of the rotor housing defining the trochoid bore, to create a suitable wear surface.
  • the distortion of the aluminium rotor housing leads to adhesion/cracking issues in surface coating, which ultimately leads to a loss in engine performance and/or increased engine maintenance.
  • the arrangement of the fixing holes and the mechanical fixing elements allows the rotor housing to expand when it becomes hotter during operation within a rotary machine, such as a rotary engine or a rotary compressor.
  • the compressive distortion of the rotor housing which occurs in prior art rotary engines may thus be reduced or substantially eliminated.
  • the associated adhesion/cracking issues in the surface coating of the trochoid bore may be reduced or substantially eliminated, which improve machine performance and/or reduce machine maintenance.
  • the effectiveness of the gas seal between the rotor housing and the endplate may be maintained and the clamping load between the rotor housing and the endplates may be maintained, may reduce or substantially eliminate surface fretting between the rotor housing and one or both endplates.
  • the rotor housing additionally has at least one single fixing hole provided therein, extending from a respective one of the sides of the rotor housing part-way into the rotor housing. At least one correspondingly located through hole is provided in a respective one of the endplates and at least one additional mechanical fixing element is located through the through hole in the respective endplate and is received in the single fixing hole.
  • each mechanical fixing element extends part-way into the respective fixing hole. This may increase the amount of thermally induced expansion which the rotor housing is able to accommodate.
  • each fixing hole is a blind hole and the rotor housing comprises solid metal between the ends of the oppositely located fixing holes of each pair. This may enable expansion of the rotor housing while maintaining mechanical strength and rigidity of the rotor housing. This may also provide improved heat transfer and less distortion of the rotor housing in the region of the fixing elements.
  • a respective connecting bore is provided through the rotor housing between the ends of the oppositely located fixing holes of each pair. This may increase the amount of thermally induced expansion which the rotor housing is able to accommodate.
  • the connecting bore has a diameter which is less than a diameter of each of the fixing holes of the respective pair.
  • the connecting bore is a tapping hole. Providing the connecting bore with a smaller diameter than the fixing holes may provide a 'stop' for the respective filing element at the end of each fixing hole.
  • the connecting bore has a diameter which is greater than a diameter of each of the fixing holes of the respective pair.
  • each mechanical fixing element comprises one of a threaded stud and a threaded bolt.
  • each fixing hole has a complementary internal thread provided on at least part of its length.
  • a first embodiment of the invention provides a rotary machine core assembly 10 comprising a rotor housing 12, a first endplate 14, a second endplate 16 and a plurality of mechanical fixing elements 18.
  • the rotor housing 12 defines a trochoid bore 20 for receiving a rotor (not shown) and comprises a plurality of cooling fins 22, arranged extending generally outwardly from the trochoid bore.
  • a plurality of pairs of fixing holes 24 are provided in the rotor housing; in this example 12 pairs of fixing holes are provided.
  • Each pair of fixing holes comprises a first fixing hole 24a and a second fixing hole 24b.
  • Each first fixing hole 24a extends from one side 12a of the rotor housing part-way into the rotor housing and each second fixing hole 24b extends from the opposing side 12b of the rotor housing part-way into the rotor housing.
  • the fixing holes 24a, 24b of each pair are generally co-axially aligned such that they extend towards each other.
  • Each fixing hole has a depth which is less than one half of the thickness of the rotor housing 12, such that the ends of the fixing holes of each pair are spaced from each other.
  • Each fixing hole is provided with an internal thread. In this embodiment a region 26 of solid metal is provided between the ends of the fixing holes.
  • Each endplate 14, 16 is provided with two dowel pins 34, in the form of straight, tubular dowels, for location in the dowel location holes 28 in the rotor housing 12, to correctly align each endplate 14, 16 against the respective side of the rotor housing.
  • mechanical fixing elements 18a, 18b are provided through each endplate 14, 16.
  • Each mechanical fixing element 18a, 18b is located through a respective through hole 30, 32 in its respective endplate and is received in the respective fixing hole 24a, 24b in the rotor housing.
  • each mechanical fixing element 18a, 18b has a length which is less than the combined depth of the respective through hole 30, 32 and the respective fixing hole 24a, 24b. The ends of oppositely located fixing elements 18a, 18b are therefore spaced from each other.
  • the mechanical fixing elements 18a located through the first endplate 14 each comprise externally threaded bolts.
  • the mechanical fixing elements 18b located through the second endplate 16 each comprise externally threaded studs, with a fixing nut located at the external end of the stud 18b to secure the stud in place.
  • each of the mechanical fixing elements 18a, 18b may be either one of a threaded bolt or a threaded stud plus a nut. Other types of mechanical fixing elements may also be used.
  • the spacing of the ends of the fixing holes 24a, 24b and the mechanical fixing elements 18a, 18b allows the rotor housing 12 to expand when it becomes hotter during operation as part of a rotary machine, such as a rotary engine or a rotary compressor.
  • a second embodiment of the invention provides a rotary machine core assembly 40 as shown in Figure 3 .
  • the rotary machine core assembly 40 of this embodiment is similar to the rotary machine core assembly 10 of Figures 1 and 2 , with the following modifications.
  • the same reference numbers are retained for corresponding features.
  • a third embodiment of the invention provides a rotary machine core assembly 50 as shown in Figure 4 .
  • the rotary machine core assembly 50 of this embodiment is similar to the rotary machine core assembly 10 of Figures 1 and 2 , with the following modifications.
  • the same reference numbers are retained for corresponding features.
  • the fixing holes 58a, 58b have larger diameter openings at the respective sides 12a, 12b of the rotor housing 12.
  • the through holes 54, 56 have correspondingly larger openings at their ends which meet the fixing holes.
  • the fixing holes 58a, 58b are spaced from each other, with a smaller separation, provided by a region 52 of solid metal between their ends.
  • a fourth embodiment of the invention provides a rotary machine 60 as shown in Figure 5 .
  • the rotary machine 60 of this embodiment takes the form of a rotary engine 60. It will be appreciated by the person skilled in the art that the rotary machine 60 may alternatively take the form of a rotary compressor.
  • the rotary engine 60 comprises a rotary machine core assembly 10 as shown in Figure 1 and a rotor 62.
  • the rotor 62 is located within the trochoid bore 20 of the rotor housing 12 and is arranged to rotate within the trochoid bore during operation of the engine 60.
  • the operation of rotary engines will be well known to the person skilled in the art and will not be described in further detail here.
