Problems solved by technology

During the use of the screw discharge centrifuge, the movement between the drum body and the screw pusher will be blocked due to reasons such as blockage, while the main drive wheel and the main differential wheel are always rotating at a constant speed, which means It will cause the main shaft of the differential to break, which not only affects the normal use of the centrifuge, but also increases the maintenance cost

Abstract

The present invention discloses a differential drive set in a spiral discharge centrifuge which can ensure that a transmission mechanism is safe and reliable. The differential drive set comprises a driving motor, a main driving wheel which is arranged in a principal axis of the driving motor in a movable way and a main differential wheel which is arranged at the principal axis of the driving motor in a stationary way. The main driving wheel and the main differential wheel are arranged together by at least one axial pin. The present invention arranges the main driving wheel and the main differential wheel together by the pin to ensure that when the resistance of the main driving wheel reaches a set value, the pin is broken, and the main driving wheel is in free state, so the transmission mechanism in the centrifuge is protected well and is avoided from being damaged.

Description

technical field [0001] The present invention relates to centrifuges, and more particularly to differential drives in screw discharge centrifuges. Background technique [0002] As we all know, a centrifuge is a machine that uses the inertial centrifugal force generated by the rotation of the drum to separate or concentrate suspensions, emulsions and other heterogeneous materials. The screw discharge centrifuge uses the mutual cooperation between the differential drive device and the differential gear installed in the centrifuge to make a certain speed difference between the rotating drum body and the screw pusher rotating in the same direction, so that the screw pusher goes up and down. The helical blades push the solid-phase filter residue deposited on the inner surface of the drum out of the drum at a stable speed. Among them, the differential drive device includes: a drive motor and a main transmission wheel and a main differential wheel arranged on the main shaft of the ...
