    摘要: A skinned rotor 201 or skinned stator 305 of a progressive cavity apparatus is described. A rotor 201 can be skinned by threading a sleeve 210 with a profiled helical outer 212 and profiled helical inner 214 surface onto a core 202 with a profiled helical outer surface 204. A rotor (1301, 1401) can also be skinned by inserting a non-helical core (1302, 1402) into a non-helical longitudinal bore (1314, 1414) of a sleeve (1310, 1410) with a profiled helical outer surface (1312, 1412). A stator 305 can be skinned by threading a tubular liner 310 with profiled helical inner 314 and profiled helical outer 312 surfaces into a profiled helical bore 308 of a tube 306. A stator (2405, 2505) can also be skinned by inserting a tubular liner (2410, 2510) with a non-helical outer surface (2412, 2512) into a non-helical bore (2408, 2508) of a tube (2406, 2506).
