BALANCING ARRANGEMENT FOR HOLLOW DRIVE SHAFTS.

摘要

A balancing arrangement for a rotating member, in which a counterweight of predetermined size an weight selected to compensate for an imbalance in the rotating member is securely fastened to the rotating member by a clamp structure extending over the counterweight to tightly engage the external surfaces of the rotating member with the counterweight in a predetermined position to thereby fixedly secure the counterweight onto the external surfaces of the rotating member in said predetermined position; the clamp structure includes a clamping band having inner and outer band end portions overlapping in the installed condition of the clamp structure with connecting means for mechanically connecting the free ends of the clamping a band and with means for tightening the clamping band about the rotating member whereby the connecting means is located within a circumferential area of the clamping band also containing at least part of the counterweight so that any weight of the connecting means is in effect additive to the weight of the selected counterweight; apertures are preferably provided in the clamping band for enhancing the effective value of the counterweight.
