Patent number: 11279016Abstract: A system includes first and second power tools that each have a percussion mechanism, a motor, and a transmission. The transmission includes a striking mechanism and is configured to transfer a driving motion of the motor to an insert tool held in a tool holder. The transmission has a guide tube that is identical in some regions along a working axis and accommodates a striker. The guide tube is rotatably coupled to the motor by a first transmission unit. The striker is driven to linearly oscillate by a piston of a second transmission unit. A ratio between a diameter of the tool holder and a diameter of the guide tube is 1.8 times greater in the first power tool than in the second power tool. A striking energy of the second power tool is mechanically reduced compared to a striking energy of the first power tool.Type: GrantFiled: June 1, 2018Date of Patent: March 22, 2022Assignee: Robert Bosch GmbHInventors: Andre Kurz, Thomas Brinkmann, Lars Schmid, Pascal Schmitz, Hardy Schmid, Patrick Heinen, Jan Koalick

Publication number: 20120279741Abstract: An electric tool includes a vibratory means which is configured to impart a counteracting vibration which counteracts a housing vibration of the electric tool. A vibration-relevant characteristic of the vibratory means can be adapted during the operation of the electric tool in such a way that the amplitude, the phase position and/or the frequency of the counteracting vibration varies with a change in the vibration-relevant characteristic. The vibratory means of the electric tool has a natural frequency which can be varied by variation means of the electric tool. A method for compensating housing vibrations, in particular of the electric tool, includes imparting a counteracting vibration by a vibratory means which counteracts a housing vibration of the electric tool. The amplitude, the phase position and/or the frequency of the counteracting vibration is varied during the operation of the electric tool.Type: ApplicationFiled: October 6, 2010Publication date: November 8, 2012Applicant: ROBERT BOSCH GMBHInventors: Gerd Schlesak, Carsten Diem, Willy Braun, Hardy Schmid, Holger Ruebsaamen, Michael Weiss, Jan Koalick, Peter Loehnert
