Abstract

1378987 Percussive tools VSESOJUZNY NAUCHNO-ISSLEDOVATELSKY I PROEKTNOKONSTRUKTORSKY INSTITUT MEKHANIZIROVANNOGO I RUCHNOGO STROITELNO-MONTAZHNOGO INSTRUMENTA VIBRATOROV I STROITELNO-OTDELOCHNYKH MASHIN 12 Dec 1972 57310/72 Heading B4C A percussive tool comprises an armature striker 13 reciprocable in response to energization of the windings 6 of a stator which is formed of two bobbin-like winding formers 7 arranged co-axially about a tubular guide path 14 for the armature striker and at least three stacks 8 of laminations 9 equispaced around the formers to provide polepieces facing the guide path at the opposite axial ends of each of the two formers, each lamination having a shape defined by a longitudinal portion, three portions normal to the longitudinal portion and a lug at each end for the purpose of mounting the lamination in the casing 1. The tool includes a cooling fan 4 and a buffer 18. The windings 6 are electrically insulated from the stacks 8 by insulating elements 12. The laminations form an E-shape and the lugs are received in clamp rings 11.
