SHUTTLE AND ROTOR ASSEMBLY WITH A BALANCING DEVICE

Abstract

 The present invention discloses a shuttle and rotor assembly with a balancing device, comprising a rotor assembly. The rotor assembly comprises a housing and multiple eccentric sleeves symmetrically arranged on the housing. The eccentric sleeves are connected to an inner cylindrical cam and an outer cylindrical cam via an adjusting component, with the inner cylindrical cam and the outer cylindrical cam being of different sizes and opposite directions. This invention relates to the field of loom technology. The shuttle and rotor assembly with the balancing device, during the high-speed operation of the rotor shuttle, the spool is subjected to a centripetal pulling force, causing frictional conflict in the area of the cam disc at the other end of the spool. The adjustment slot is an annular groove, and the ball is placed on the surface of the adjustment slot. The ball, inner cylindrical cam, and outer cylindrical cam are all installed inside the eccentric sleeve. The ball can contact the inner wall of the eccentric sleeve and make fine distance adjustments. The inner cylindrical cam and outer cylindrical cam can rotate, thereby offsetting the impact of manufacturing errors and achieving the requirements for normal operation at low precision, thus reducing production costs.
