MINING MACHINE REDUCTION DRIVE DISENGAGEMENT MECHANISM

摘要

1. Technical field: mining machinery. 2. Direct application: in devices for the mechanical disengagement of engines from reduction drives of a cutting tool actuator. 3. Essence of the invention: it is proposed to provide a shaped recess (21-22) along the longitudinal axis (X) of a cup (3), in the form of a groove (21) connected to a nest (22), and to fasten a rod (2) in the recess in an initial position in such a way that a flat area (10) provided on the rod (2) is situated transversely to the longitudinal axis (X) of the cup (3), wherein the rod (2) is installed in the rear portion (4) of the cup (3) and is positioned in the shaped recess with the ability to rotate in the nest (22) and to move in the groove (21) along the longitudinal axis (X) of the cup (3), and the thickness (L10) of the rod (2) with the flat area (10) is made to be proportional to the width (L21) of the groove (21). 4. Technical result: increasing the operational reliability and decreasing the activation time of a reduction drive disengagement mechanism.
