Description

Technical Field

[0001] The invention relates to the technical field of spinning machines, in particular to a twisted ring spindle in a spinning machine component. Background Art

[0002] The fancy twist ring spindle comprises a spindle rod, a spindle disk and a spindle rod seat. The spindle rod seat is fixed on the dragon tendon of the spinning machine. The lower section of the spindle rod is rotatably arranged in the spindle rod seat, and the upper section extends out from the spindle rod seat. The spindle disk is sleeved on the upper section of the spindle rod. The contact surface between the spindle disk and the spindle rod is a conical surface, which plays a centering and supporting role. The driving belt is wound around the belt surface of the spindle disk to drive the spindle disk to rotate. The yarn bobbin is sleeved on the spindle rod and falls on the spindle disk. The upper end face of the spindle disk is provided with a driving column inserted into the driving hole on the lower end face of the yarn bobbin. The spindle rod and the spindle disk are rotating parts, and the spindle rod seat is a fixed part.

[0003] Since the working speed of the ring spindle is relatively high, there is an eccentricity problem with different degrees of yarn bobbins. Therefore, the ring spindle itself needs to have a shock-absorbing structure and a structure that is easy to maintain. The structure that is easy to maintain mainly refers to that the spindle rod is easy to take out and replace the bearing. The structure of the existing fancy twist ring spindle is that the spindle rod seat adopts a structure with a closed lower end, that is, the spindle rod seat is a cylinder with an open upper end and a closed lower end, and the lower end of the spindle rod is in the form of a spherical surface against the inner bottom surface of the spindle rod seat, and a detachable bearing is arranged at the upper end of the spindle rod seat to realize the rotation support of the spindle rod, and the spindle rod can be pulled out from the spindle rod seat to realize the addition of spindle oil to the spindle rod seat and / or replacement of the bearing. A coil spring for shock absorption is also arranged in the annular cavity between the spindle rod and the spindle rod seat. In addition to lubricating the friction spherical surface and bearing of the spindle rod, the spindle oil also has the function of absorbing the vibration of the spindle rod. Due to the large number of spindles in each device, this structure using spindle oil is prone to cause: First, high-speed rotation is prone to cause spindle oil overflow and pollute the surrounding environment; Second, the process of adding spindle oil increases maintenance costs and reduces equipment utilization. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a twisted ring spindle, which can achieve vibration reduction and ensure convenient maintenance of the ring spindle without using spindle oil, avoid environmental pollution and reduce downtime.

[0005] The technical solution adopted by the present invention to solve its technical problems is: a kind of twisted ring spindle, comprising a spindle rod, a spindle disc and a spindle rod seat, the spindle rod seat is used to support the spindle rod and to fix the twisted ring spindle on the dragon tendon of the spinning machine, the lower section of the spindle rod is inserted into the spindle rod seat and rotatably arranged in the spindle rod seat, the upper section extends from the spindle rod seat, the spindle disc is sleeved on the upper section of the spindle rod, the assembly surface of the spindle disc and the spindle rod is a conical surface, the spindle disc has a driving surface in contact with the driving belt, the spindle rod seat is cylindrical, the structure of the lower section of the spindle rod rotatably arranged in the spindle rod seat is that the upper and lower ends of the spindle rod seat are respectively provided with an upper bearing and a lower shaft for supporting the spindle rod The inner bearing ring of the upper bearing is sleeved on the spindle rod and pressed on the step of the spindle rod, the outer bearing ring is pressed on the upper step of the inner wall of the spindle rod seat, and an upper shock-absorbing ring is provided in the annular space between the outer bearing ring of the upper bearing and the inner wall of the spindle rod seat; the outer bearing ring of the lower bearing is pressed on the lower step of the inner wall of the spindle rod seat, and the inner bearing ring is pressed on the positioning retaining ring clamped on the spindle rod, the inner bearing ring of the lower bearing is sleeved on the annular lower shock-absorbing ring, the lower shock-absorbing ring is sleeved and axially positioned on the ring groove of the spindle rod, and a sealing cover is sleeved on the lower end of the spindle rod with a gap, and an anti-dropping retaining ring clamped on the inner wall of the spindle rod seat is provided below the sealing cover.

[0006] Specifically, the cost can be reduced by using standard parts, and the upper damping ring is at least two stacked O-rings.

[0007] Likewise, the lower shock-absorbing ring is at least two stacked O-rings.

[0008] Specifically, in order to improve the shock-absorbing effect, the twisted ring spindle also includes an upper semi-rigid shock-absorbing ring and a lower semi-rigid shock-absorbing ring, both of which are mounted on the spindle rod seat but are respectively located above and below the dragon tendon. The upper semi-rigid shock-absorbing ring is tightly fitted on the spindle rod seat, a brake is provided above the upper semi-rigid shock-absorbing ring, and a lower clamping piece is provided below the lower semi-rigid shock-absorbing ring.

[0009] Specifically, the lower clamping member is a fastening nut threaded onto the spindle rod seat.

[0010] Specifically, since the spindle rod seat needs to withstand a certain axial force of the spindle rod, the deep groove ball bearing is the most common bearing that can withstand a certain axial force. Therefore, the upper bearing is a deep groove ball bearing, and the lower bearing is also a deep groove ball bearing.

[0011] The beneficial effects of the present invention are:

[0012] 1. The spindle rod is supported by two upper and lower bearings. A shock-absorbing ring is set on the outer ring of the upper bearing and the inner ring of the lower bearing. The upper bearing can be pulled out from the spindle rod seat along with the spindle rod, and the lower bearing remains in the spindle rod seat. When the spindle rod is pulled out, it only needs to overcome the resistance of the shock-absorbing ring, so the maintenance of the spindle rod is more convenient;

[0013] Second, the shock-absorbing structure between the spindle bar and the spindle bar seat can be further combined with the shock-absorbing structure between the spindle bar seat and the dragon tendon, which can better reduce the impact of the spindle bar vibration on the equipment;

[0014] 3. No spindle oil is used, which avoids environmental pollution and avoids downtime due to adding spindle oil. BRIEF DESCRIPTION OF THE DRAWINGS
