Whole-type bearing high-speed spinning spindle with detachable and washable spindle feet

Abstract

The invention relates to a whole-type bearing high-speed spinning spindle with detachable and washable spindle feet. The whole-type bearing high-speed spinning spindle comprises a spindle base and a rod disc, the spindle base is composed of the spindle feet and a bolster, abrasive particles can be removed by directly disassembling and washing oil storage cups in the spindle feet, vibration is transmitted to spindle foot tubes through a vibration attenuation sleeve and lubricating oil in a two-time mode, the vibration energy consumption can be effectively reduced, and the service life of the spindle is prolonged. The inner wall of a bearing base, the upper end face of an elastic pipe and the lower end of an oil proofing cap in the bolster serve as an outer ring, a lower bearing plate and an upper bearing plate of a roller respectively, a whole-type bearing structure is combined, a spinning spindle bearing, the upper bearing plate and the lower bearing plate are removed, the requirement for the fit accuracy between parts is lowered, the concentricity of bearing holes is guaranteed, and stress of the holes in the radial direction is even. Meanwhile, as the outer diameter of the bearing base is reduced, the diameter of a spindle disc of the spindle is accordingly reduced, high-speed operation of the smaller spindle disc can be adapted, and the operation speed ranges from 25000 r/min to 30000 r/min.

Description

technical field [0001] The invention relates to a component of a textile ring spinning machine, in particular to a high-speed spinning spindle with an integral bearing with detachable and washable spindle feet. Background technique [0002] Spindle is the key component for twisting and winding in the spinning frame, and the spindle foot is the support and oil storage part of the spindle. The traditional spindle foot is an integral structure made of castings or steel billets, which is difficult to process and occurs during operation. The metal abrasive particles remain in the inner cavity, which makes cleaning and changing oil and maintenance troublesome, and the vibration absorption effect is poor, which affects the service life of the spindle. In the core structure of the traditional spindle, the spindle bearing with the outer ring and the upper and lower bearing plates is pressed into the inner hole of the bearing housing. Since the installation inner holes of the spindle ...
