摘要： A hand-held power tool is provided with a drive motor and a clutch connected to the drive motor. The drive motor drives a tool member through the clutch. The clutch has a clutch drum with a circumferential wall provided with an end face. A follower member engages a groove in the circumferential wall of the clutch drum and a driven element is connected to the follower member to be driven by the follower member. The groove extends from the end face of the circumferential wall into the circumferential wall and has a groove bottom and two groove sides positioned opposite each other. The circumferential wall has a protrusion located at the groove bottom. The protrusion has a protrusion thickness measured at the groove bottom that amounts to at least approximately 110% of a wall thickness of the circumferential wall measured at the two groove sides.

摘要： A balancing element for balancing a friction clutch, including a balancing head for providing a balancing mass, and a shaft that is connected to the balancing head, is to be inserted into an opening in the friction clutch, and has a shaft end which points away from the balancing head and which includes a face pointing away from the balancing head substantially in the axial direction of the shaft. The shaft end has a weakening in the material in a subsection between the face and the balancing head in order for the shaft end to plastically deform radially outward in relation to the longitudinal axis of the shaft when a compressive force is applied to the balancing head in the axial direction. This especially allows the face of the shaft end to about a part of the friction clutch once the shaft has been introduced into a receiving opening in the friction clutch, and makes it possible to apply a compressive force to the balancing head in the direction of insertion, said compressive force being so great that the shaft end is plastically deformed in a particularly easy manner in the region of the weakening in the material such that a secure form-fitting connection is established, thereby preventing the balancing element from coming loose again even when the assembly space is tight and keeping the risk of the friction clutch becoming unbalanced low during the entire service life of the friction clutch.

摘要： The present invention provides improved clutch plates for use in wet friction pack clutches and brakes which exhibit greatly reduced flutter particularly at high rotational speeds. Friction clutches and brakes include a first plurality of circular clutch plates or discs coupled to a first member comprising a metal core plate having bands of friction material affixed to both faces. These clutch plates are interleaved with a second plurality of circular metal reaction plates which are coupled to a second member. The metal core plate of the first plurality of clutch plates includes a plurality of radial slots spaced about the core plate which extend inwardly a portion of the radial width of the clutch core plate. Different numbers of slots, different spacings and different configurations of slots provide reduced plate flutter with varying thicknesses of core plates and ranges of rotational speeds.
