Abstract:
PCT No. PCT/EP87/00394 Sec. 371 Date Mar. 29, 1988 Sec. 102(e) Date Mar. 29, 1988 PCT Filed Jul. 20, 1987 PCT Pub. No. WO88/00873 PCT Pub. Date Feb. 11, 1988.A rig puller for removing rings from shafts to which they are affixed. The puller is formed by a steel heat accumulator ring having a slot separating the ring into a band having separated ends. An electrical conductor extends between the ring ends, and a clamping device is provided to force the ring ends towards each other about a ring to be removed. By utilizing steel which as compared to most metals and more particularly aluminum has relatively low specific heat and thermal conductivity, the ring may be efficiently heated inductively and used immediately to effect expansion of the ring to be removed without requiring cleaning where the accumulator ring had been heated in an oil bath or the like as previously.
