Description

Technical Field

[0001] The utility model relates to the technical field of bearings, in particular to a roller head bearing used for the tail of a spinning machine. Background Art

[0002] The spinning frame is a spinning machine that drafts, twists, and winds semi-finished roving or sliver into fine cops during the spinning process. The sliver is drafted and twisted on the roving frame to produce roving, the sliver is drafted and twisted on the spinning frame to produce fine yarn, the sliver is drafted and twisted on the roving frame to produce roving, the combing machine combs the fibers to produce combed sliver, the gilling machine combines the slivers, and the pin bar drafting improves the sliver structure. The roving is further twisted and spun on the ring spinning frame to produce fine yarn. The spinning frame is the primary machine in spinning, and the yield and quality of fine yarn are a comprehensive reflection of the quality of each step in the spinning process.

[0003] Roller heads are cylindrical rotating parts in textile machinery that perform functions such as feeding, drafting, and output. They are a transliteration of the English word "roller," meaning both roller and shaft. They are widely used in drafting, carding, and conveying mechanisms. They are categorized by their function as drafting rollers, feed rollers, pressure rollers, and work rollers. Drafting rollers are key components of the spinning machine's drafting mechanism. They consist of a pair of upper and lower rollers that form the roller mouth, gripping the yarn for drafting. Roller heads are a crucial component of the spinning frame. The roller heads at the tail of the spinning frame are equipped with bearings, typically thrust and needle bearings. However, after about 20 days of use, the thrust and needle bearings can cause significant wear and tear, resulting in a short service life for the roller heads. This poses a significant risk of machine breakdown, and frequent replacement increases worker workload, impacting production efficiency and yarn quality. Utility Model Content

[0004] In order to overcome the defect of severe wear of roller heads in the prior art, the utility model provides a roller head bearing for the tail of a spinning machine.

[0005] The technical solution adopted by the utility model to solve the technical problem is: a roller head bearing for the tail of a spinning machine, comprising a roller head, a deep groove ball bearing is provided on the roller head, the deep groove ball bearing comprises an outer ring and an inner ring, and a plurality of steel balls are arranged between the outer ring and the inner ring.

[0006] As a further improvement of the present invention, the plurality of steel balls are connected via a retaining frame.

[0007] As a further improvement of the present invention, a plurality of oil holes are provided in the inner ring.

[0008] As a further improvement of the present invention, an oil cavity communicating with the oil hole is provided inside the inner ring.

[0009] As a further improvement of the present invention, the outer ring and the inner ring are made of stainless steel.

[0010] As a further improvement of the present invention, grooves for fitting the steel balls are provided on the inner wall of the outer ring and the outer wall of the inner ring.

[0011] Compared with the existing technology, the utility model has the beneficial effects: in this solution, a deep groove ball bearing is provided on the roller head, the deep groove ball bearing includes an outer ring and an inner ring, and a number of steel balls are provided between the outer ring and the inner ring. The thrust bearing on the roller head is replaced with a deep groove ball bearing, and the needle bearing is removed, which can effectively prevent the wear of the roller head.

[0016] In order to make the technical solution and beneficial effects of the present invention more clearly understood, the present invention will be further described in detail below with reference to specific embodiments.

[0017] Reference Figure 1 and Figure 2 The present invention discloses a roller head bearing for the tail of a spinning machine, comprising a roller head 1, on which a deep groove ball bearing 2 is mounted. The deep groove ball bearing 2 includes an outer ring 3 and an inner ring 4, with a plurality of steel balls 5 disposed between the outer ring 3 and the inner ring 4. By replacing the thrust bearing on the roller head 1 with the deep groove ball bearing 2 and removing the needle bearing, wear of the roller head can be effectively prevented.

[0018] The inner ring 4 is provided with a plurality of oil holes 7, and an oil cavity 8 is provided inside the inner ring 4, which is connected to the oil holes 7. Oil is added to the oil cavity 8 and the oil holes 7, and the oil flows through the oil holes 7 into the position where the roller head 1 and the steel balls 5 are located, which has a good lubrication effect. On the one hand, it reduces the wear of the roller head 1 and the deep groove ball bearing 2, and on the other hand, it reduces the wear of the steel balls 5.

[0019] The outer ring 3 and the inner ring 4 are made of stainless steel, which is more wear-resistant. The inner wall of the outer ring 3 and the outer wall of the inner ring are provided with grooves for matching the steel balls 5. Several steel balls 5 are connected by a retaining frame 6, so that the steel balls 5 roll more smoothly between the outer ring 3 and the inner ring 4.

[0020] It should be understood that the specific embodiments described herein are only used to understand the present invention and are not used to limit the present invention. All other embodiments obtained by those skilled in the art without making any creative work are within the scope of protection of the present invention.
