ABSTRACT:
A braking device for drive motors is disclosed. The braking device includes a brake disk which is adapted to be moved axially by the exertion of a spring force which acts against the rotor of the motor when the motor winding is de-energized. Such axial movement causes the brake disk to engage an oppositely disposed brake lining of the braking device, the latter lining being connected to a stationary part of the device.
In accordance with the invention, the brake lining and the brake disk are configured such that their mutual contact surfaces are arranged in the manner of a cone brake which is at an angle to the rotor displacement and the line of force of the spring. Additionally, the brake lining is resiliently connected, at least in the radial direction, via an elastic intermediary member, with the stationary part of the device. As a result, self-centering of the brake lining occurs when it is engaged by the brake disk.
