WEDGE FOR PREVENTING NOISE OF DC ELECTRIC MACHINE
Document Type and Number:
Japanese Patent JPS56145741
Kind Code:
A
Abstract:
PURPOSE:To effectively prevent the vibration and the noise of an interpole with a simple mounting work by mounting a wedge having a recess for receiving the end of a central pole of an E-shaped interpole at one side end and a projection for preventing the removal thereof at the other side end in the gap between the end of the central pole and the end of the leg pole of the interpole. CONSTITUTION:A wedge 2 is mounted between the edge 3a of a leg pole 3 and the edge 4a of a central pole 4 of an E-shaped interpole 1. The wedge 2 has a recess 5 formed at one side end for receiving the edge 4a of the leg pole and a projection 7 formed at the other side end for preventing the removal thereof together with a tapered shoulder part 6 in such a manner that the substanital width B is larger than the distance A between the edges 3a and 4a. The wedge 2 is mounted by initially engaging the recess 5 with the edge 4a of the central pole, and then pressing the projection 7 with the shoulder part 6 as a guide until it engages with the inside of the edge 3a of the leg pole.
