Damping vibration attenuation metacentric-type electric spindle centrifugal machine

Abstract

The invention discloses a damping vibration attenuation metacentric-type electric spindle centrifugal machine and aims at solving the problems that a motor rotor of an existing chemical fiber and textile fiber centrifugal spinning electric spindle centrifugal machine is in a rigid connection with a centrifugal spinning pot of the existing chemical fiber and textile fiber centrifugal spinning electric spindle centrifugal machine, and in the process of starting, normally operating and stopping of the electric spindle centrifugal machine, the factors such as manufacturing and installation of the centrifugal spinning pot, and spinning and spindle forming of the fiber in the centrifugal spinning pot cause dynamic unbalanced inertia moment to influence normal operation of equipment and even damage the equipment. The damping vibration attenuation metacentric-type electric spindle centrifugal machine comprises a base, an electric spindle shell body, the motor rotor, a hollow output shaft, a cone-shaped central spindle, the centrifugal spinning pot and an upper back-up bearing. On the premise of fully retaining the advantages of the existing electric spindle centrifugal machine, the damping vibration attenuation metacentric-type electric spindle centrifugal machine is capable of effectively improving reliability of equipment operation, prolonging service life, reducing power loss and energy consumption, improving the comprehensive performance index of the equipment through adoption of an improved structure, and effectively solves the problems of fatigue bearings, short service life, large energy consumption, high damage rate and high manufacturing cost, and the like of the existing electric spindle centrifugal machine.

Description

technical field [0001] The invention relates to the field of machinery, in particular to the field of textile machinery, and specifically relates to a damping, vibration-reducing and stable-center electric spindle centrifuge, which is mainly used for centrifugal spinning of chemical fibers and textile fibers. Background technique [0002] The existing electric spindle centrifuges for centrifugal spinning of chemical fibers and textile fibers are mainly composed of a centrifugal tank, a fixed plate, a solid shaft, a hollow shaft, a motor rotor, a motor stator, an upper support bearing, a lower support bearing, a fixed casing and a bracket, etc. . The existing electric spindle centrifuge has compact structure and low cost, but it also has some disadvantages. [0003] The motor rotor and the centrifuge tank are rigidly connected. During the start-up, normal operation and shutdown of the electric spindle centrifuge, a dynamic unbalanced moment of inertia is formed due to factor...
