摘要： A hand-held processing tool with a housing that includes at least two housing parts is disclosed. The housing parts each have a side edge which are directly adjacent to one another in the assembled state of the housing. A recess is provided in at least one partial region of the side edges of at least one of the two housing parts such that the side edges of the at least two housing parts are spaced apart from one another in the at least one partial region.

摘要： A hand-held power tool device, in particular a hammer drill and/or chisel hammer device, includes at least one operating element and at least one locking unit. The at least one locking unit includes at least one locking element and at least one controllable actuator element. The at least one locking element can be moved from at least one storage position into at least one locking position, and vice versa, and locks the operating element in at least one operating state in the locking position. The at least one controllable actuator element influences motion of the locking element.

摘要： A hand-held power tool includes a housing in which a drive unit and an impact-mechanism unit are arranged. The hand-held power tool further includes a tool-receiver interface configured to releasably connect with a tool receiver, the tool receiver configured as a stirrer-basket receiver. A user interface is configured to set at least one of a rotary-hammer mode and a stirring mode for the hand-held power tool.

摘要： 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.

摘要： A bearing device includes at least one bearing element. The at least one bearing element has at least one bearing running surface and at least one lubricant pocket. The at least one lubricant pocket is configured to lubricate at least a portion of the bearing running surface of the at least one bearing element. A method of producing the at least one bearing element includes forming the at least one lubricant pocket in the at least one bearing element at least partly by a non-cutting production method.
