Abstract

1379744 Vibrators ROBERT BOSCH GmbH 8 Dec 1971 [9 Dec 1970] 56956/71 Heading B1C [Also in Division F2] A vibrator, e.g. for submersion in concrete, has an eccentric mass 29 driven by an electric motor 35 mounted in an extrusion moulded tube 2 closed at one end by an integral end wall 5, and a replaceable cap 18, e.g. of an elastomeric material or hardened steel. The cap is held against release, due to vibration, by one of the bent up ends of a spring washer 24 cooperating with saw teeth 23 or the cap. Precision-machined seals 8, 12 are provided for a roller bearing 9 and a ball bearing 13 respectively, which 'bearings support the eccentric mass. A cover 47 for closing the open end of the tube includes a bore 49 for receiving a sintered bearing bush 50 (or a needle or roller bearing) for the trunnion 61 of the rotor 36 of the motor which is a high frequency 3-phase motor. The other end of rotor has a recess 60 which receives a projection 31 of the eccentric mass. The stator 37 which is laminated is located in the tube by spacing sleeves 34, 46 and has cement applied to its outer surface prior to insertion in the tube. When the vibrator has been assembled the cover 47 is welded to the tube, and foam material is injected into the interior of the cover.
