Abstract (en)
[origin: EP2666961A1] A rotary machine core assembly (10) comprising a rotor housing (12), first and second endplates (14, 16) and mechanical fixing elements (18a, 18b). The housing defines a trochoid bore (20) and has a plurality of pairs of fixing holes (24a, 24b) provided therein. A first fixing hole (24a) of each pair extends from one side (12a) of the housing and a second fixing hole (24b, 42b) extends from an opposing side (12b) of the housing. Each fixing hole extends part-way into the rotor housing. The fixing holes extend towards each other and have a depth such that their ends are spaced from each other. The endplates (14, 16) are located adjacent respective sides of the housing. Each endplate has a plurality of through holes (30, 32) provided in it which are correspondingly located with the fixing holes on the rotor housing. Each mechanical fixing element is located through a respective through hole in an endplate and is received in the respective fixing hole in the rotor housing.
