Description

Technical Field

[0001] This utility model belongs to the field of spindle technology, specifically relating to a novel spindle structure. Background Technology

[0002] The spindle is a core component of textile machinery, and its rotational stability directly affects yarn quality. Traditional spindles are prone to settling when subjected to axial loads in textile machinery, and the internal lubricating oil is prone to overflow during rotation, leading to accelerated spindle wear and shortening spindle life. Utility Model Content

[0003] The main objective of this invention is to provide a novel spindle structure that reduces the possibility of spindle rod settling and lubricant leakage.

[0004] To achieve the above objectives, this utility model provides a novel spindle structure, which includes a spindle rod, on which an elastic tube assembly is provided. The upper end of the elastic tube assembly is provided with a stepped structure, and several spacer plates are provided along the inner sidewall of the elastic tube on the stepped structure. Ball bearings are provided between the spacer plates. Several support rods are provided along the outer wall of the spindle rod, and the bottom end of the support rod is provided on the ball bearings.

[0005] The novel spindle structure provided by this utility model allows the support rod to transfer the weight of the spindle to the ball bearings. Under the constraint of the stepped structure, the ball bearings convert the vertical load into a radially dispersed force, reducing the risk of settlement.

[0006] In one possible implementation, the top of the elastic tube assembly has a first anti-overflow groove on its inner sidewall, and the top of the first anti-overflow groove is configured as a barbed groove. When the spindle rotates, the lubricating oil is subjected to centrifugal force and is thrown towards the sidewall, thereby preventing lubricating oil from overflowing through the barbed groove.

[0007] In one possible implementation, a second anti-overflow groove is provided on the nail rod, the second anti-overflow groove being disposed on the outer wall of the nail rod and located inside the elastic tube assembly, above the support rod. The second anti-overflow groove and the first groove form an oil barrier zone, further ensuring that lubricating oil will not overflow or leak through double protection.

[0008] In one possible implementation, the top height of the second spill containment tank is lower than the top height of the first spill containment tank, and the bottom height of the second spill containment tank is higher than the bottom height of the first spill containment tank.

[0009] In one possible implementation, the spindle rod is installed inside a spindle foot tube, the bottom end of which has a perforated chip storage area for storing worn-off chips. A plug screw is located at the bottom of the spindle foot tube. Metal chips fall into the storage area through the perforated holes, preventing chips from embedding in the ball bearing track and causing jamming. Attached Figure Description

[0011] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art. The basic principles of the present invention defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.

[0012] In the description of this application, it should be understood that the terms "upper" and "lower" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0013] In the description of this application, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated.

[0014] See attached diagram. Figure 1 and Figure 2 As shown in the figure, this utility model provides a novel spindle structure, which includes a spindle rod 1, an elastic tube assembly 2 on the spindle rod 1, a stepped structure at the upper end of the elastic tube assembly 2, a plurality of spacers along the inner sidewall of the elastic tube on the stepped structure, ball bearings 3 between the spacers, and a plurality of support rods 4 along the outer wall of the spindle rod, with the bottom end of the support rod 4 mounted on the ball bearings 3.

[0015] The novel spindle structure provided by this utility model allows the support rod 4 to transfer the gravity of the spindle rod 1 to the ball bearings 3. Under the constraint of the stepped structure, the ball bearings 3 convert the vertical load into a radially dispersed force, reducing the risk of settlement.

[0016] In one possible implementation, the top of the elastic tube assembly 2 has a first anti-overflow groove 51 on its inner sidewall, and the top of the first anti-overflow groove 51 is configured as a barbed groove. When the spindle rotates, the lubricating oil is subjected to centrifugal force and is thrown towards the sidewall, thereby preventing the lubricating oil from overflowing through the barbed groove.

[0017] In one possible implementation, a second anti-overflow groove 52 is provided on the nail rod. The second anti-overflow groove 52 is located on the outer wall of the nail rod, inside the elastic tube assembly 2, and above the support rod 4. The second anti-overflow groove 52 and the first groove form an oil barrier, further ensuring that the lubricating oil will not overflow or leak through double protection.

[0018] In one possible implementation, the top height of the second spill containment tank 52 is lower than the top height of the first spill containment tank 51, and the bottom height of the second spill containment tank 52 is higher than the bottom height of the first spill containment tank 51.

[0019] In one possible implementation, the spindle rod 1 is installed inside the spindle foot tube, and the bottom end of the spindle foot tube is provided with a perforated chip storage area 6. The storage area is used to store chips that have fallen off due to wear, and a plug screw 7 is provided at the bottom of the spindle foot tube. Metal chips fall into the storage area through the perforated holes to prevent chips from getting embedded in the track of the ball bearing 3 and causing jamming.

[0020] It is worth mentioning that those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
