Abstract:
1. A transmission device for a rotary and/or chisel hammer comprising: a torque transmission mechanism having a first torque transmission region for transmitting a torque with a first component and at least one second torque transmission region for transmitting a torque with a second component, wherein the first torque transmission region and the at least one second torque transmission region at least partially have a matching contour for transmitting the torques, wherein the torque transmission mechanism surrounds an intermediate shaft of the rotary and/or chisel hammer and is rotatably supported on the intermediate shaft, wherein the first torque transmission region and the at least one second torque transmission region are disposed on a radially outward-oriented surface of the torque transmission mechanism, and wherein the first torque transmission region has a lesser addendum circle radius than an addendum circle radius of the at least one second torque transmission region, and has an identical root circle radius.
