Abstract

A találmány lapátzár axiális turbinához, ahol a lapátok (3) a turbinajárókerekének (1) hátrametszett lapáthornyába (2) vannak behelyezve ésa lapáthorony (2) legalább egy befűzési hellyel áll kapcsolatban és abefűzési helyen egy, a lapátok (3) lapátlábával (6) formazáró töltődarab (8) és egy ék (9) van behelyezve. A találmány lényege, hogy abefűzési helynek, a töltődarabot (8) felvevő keresztmetszete alapáthoronyból kiindulva kónuszosan bővül és a töltődarab (8)keresztmetszete a befűzési hely keresztmetszetéhez van igazítva. Atalálmány továbbá eljárás lapátzár előállítására, amelynek lényege,hogy a lapáthorony (2) kimunkálása után a lapáthoronyhoz (2) előregyártott töltődarabot (8) az előkészített befűzési helybe behelyezikés az ékkel (9) rögzítik, a lapáthorony (2) kontúrját a lapáthoronyba(2) és egyidejűleg a töltődarabba (8) bemunkálják a töltődarabot (8)és az éket (9) a befűzési helyből kiveszik és azután a turbinajárókereket (1) a lapátokkal (3) ellátják és a lapátokat (3) alapáthoronyban (2) a lapátzárral biztosítják.
