Abstract

Protection arrangement for units for rotation of excavator buckets, by means of an output shaft (8), a hydraulic motor (20) and also, between the motor and the output shaft, a transmission (12, 13). The transmission (12, 13) is a self-braking worm transmission whose worm screw (13) has bearings which permit axial movement of the screw under the effect of forces in the transmission. A spring arrangement (25) holds the screw in a normal position up to a certain level of force effect. A detection member (25) detects the axial position of the screw and is coupled to a control arrangement (23) connected to the motor. In the event of force effect over the said level, the screw moves axially and the detection member couples the motor (20) to the drive source for rotation in the direction of the force effect. As a result of the turning of the output shaft in the direction of the force effect, the unit is protected from breaking due to excessively great, external forces.
