Technical Field

[0001] The utility model relates to the technical field of spinning frames, in particular to a spindle vibration absorbing structure for an oil-saving spinning frame. Background Art

[0002] The spindle is one of the main twisting and winding parts in the spinning frame and is a symbol of the textile industry. Under normal working conditions, the spindle runs at the rated working speed. If the frequency of this working speed is close to the natural frequency of the spindle, the spindle will resonate and a large amplitude will appear at the same time. The amplitude is likely to affect the output and quality of the spinning frame. Therefore, a fuel-saving spinning frame spindle vibration absorption structure is used;

[0003] To this end, the patent with publication number CN212476993U discloses a vibration-absorbing mounting structure for a single motor spindle of a spinning machine, including an electric spindle, a mounting seat, a first axial vibration isolation ring, a radial vibration isolation ring, a second axial vibration isolation ring, a pressure ring and a positioning clamp ring. The electric spindle is composed of a motor and a spindle rod combination on which a vibration isolation ring housing can be installed; the electric spindle is arranged on the mounting seat, at least one radial vibration isolation ring is arranged between the electric spindle and the mounting seat, axial vibration isolation rings are arranged at both ends of the mounting seat, the positioning clamp ring is arranged on the electric spindle, a pressure ring is arranged between the positioning clamp ring and the second axial vibration isolation ring, and the pressure ring is arranged on the electric spindle. The vibration isolation ring configuration of the utility model adopts a full range of radial vibration isolation and axial vibration isolation, which effectively absorbs the eccentricity and vibration generated by the electric spindle during operation. The eccentricity and vibration generated by the electric spindle during operation are adapted and absorbed by the elastic material layer between the motor and the mounting seat, which has the effect of stabilizing the operation of the electric spindle;

[0004] The above-mentioned vibration-absorbing mounting structure for the single-motor spindle of a spinning machine effectively absorbs the eccentricity and vibration generated by the spindle during operation. However, when the spindle is working, it is inconvenient to limit its bottom, which causes the spindle to swing easily during operation, making it less suitable for use. Utility Model Content
