摘要:
A tool-handling device for an insert tool(14) equipped with an at least essentially disk-shaped hub (42), in particular for a hand guided angle grinder (32) or a hand-guided circular saw, having a drive shaft (16) and a drive device (12) equipped with at least one locking element(20) that is supported so that it is able to move in relation to a spring element (18) in order to fix the insert tool (14) in a form-locked manner in the circumference direction (50, 52).The drive shaft (16) has at least one form-locking element (100) formed onto it in a non-cutting manner in order to connect it in a form-locked manner in the circumference direction (50, 52) to a drive torque-transmitting mechanism of the drive device (12).
摘要:
The invention relates to a tool receiving device for a machine tool (14), comprising an at least essentially disk-shaped hub (42), particularly for a hand-guided angle grinder (32) or a hand-held circular saw. Said tool receiving device also comprises a drive shaft (16) and a receiving device (12) comprising at least one catching element (20) which can be displaceably mounted against a spring element (18) in order to fix the machine tool in a positive fit in the direction of the periphery (50, 52). According to the invention, the drive shaft (16) comprises at least one shaped positive fit non chip-removing element (100) which is connected in a positive fit in the direction of the periphery (50, 52) to means for the transmission of drive torque in the receiving device (12).

摘要:
In a hand power tool having a housing which at least in part comprises an inner housing and an outer housing, and in which the inner housing and the outer housing are spaced apart from one another, at least one damping element is provided between the inner housing and the outer housing, so that the inner housing and the outer housing are decoupled from one another.
摘要:
A gear mechanism, in particular for hand power tools, is disclosed which has a driving gear wheel (12), seated on a drive shaft (11) in the manner fixed against relative rotation, and a driven gear wheel (13), meshing with the driving gear wheel and driving a driven shaft (14). To attain high running smoothness of the gear mechanism and a longer service life by reducing the mechanical load on the gearing upon startup and in load peaks that occur during operation, spring-elastic damping elements (22) are located between the driven gear wheel (13) and the driven shaft (14) (FIG. 2).
摘要:
A power tool brake mechanism, in particular a portable power tool brake mechanism, includes at least one mechanical brake unit that has at least one brake element mounted rotatably about a rotation axis and at least one actuating unit that has at least one movably mounted actuating element. The actuating unit is configured to activate and/or deactivate the brake unit. The power tool brake mechanism further includes at least one movement converting unit that has at least one movement converting element configured to convert a movement of the actuating element into a movement of a counter-brake element of the brake unit. The movement of the counter-brake element is at least in a direction that is different from a direction extending along the rotation axis of the brake element.
