AI Technical Summary
Technical Problem
Existing false twisters have complex spindle assembly, high cost, and are prone to vibration due to bearing axial clearance.
Method used
The design employs a combination of shaft, outer cylinder, bearing, ball bearing, washer, and L-shaped damping ring. Through interference fit and damping ring chamfering, the assembly process is simplified and radial and axial damping forces are provided, eliminating bearing clearance.
Benefits of technology
It reduces the manufacturing cost of the false twister spindle, improves operating accuracy and stability, and reduces vibration.

Abstract
The utility model relates to a false twister spindle and a false twister unit. The false twister spindle comprises a spindle body, an outer cylinder, a bearing, a plurality of balls, a gasket and an L-shaped damping ring. The outer cylinder is coaxially arranged on the peripheral side of the shaft body in a sleeving manner; the bearing is arranged between the shaft body and the outer cylinder in the radial direction; the plurality of balls are arranged between the shaft body and the outer cylinder in the radial direction and are arranged on one side of the bearing in the axial direction; the gasket is arranged between the shaft body and the outer cylinder in a sleeved mode in the radial direction and arranged on the side, away from the balls, of the bearing in the axial direction. The L-shaped damping ring comprises an axial extension part and a radial extension part, the axial extension part is arranged between the bearing and the outer cylinder in the radial direction, and the radial extension part is arranged between the bearing and the gasket in the axial direction. According to the false twister spindle, the design is simplified, the assembly process is easier, and the manufacturing cost is reduced.
