Description

Technical Field

[0001] The utility model belongs to the technical field of textile rollers, in particular to a roller bearing structure that can be used with or without lubrication. Background Art

[0002] The top roller bearings, also known as top roller bearings, are widely used on domestically produced spinning machines. They play a role in drafting and pulling the yarn during the spinning operation of the spinning machine. The stability of the bearing operation will be directly related to the quality of yarn drafting and pulling, and affect the thickness of the yarn evenness, which is especially obvious for high-grade and high-count yarns. In the field of industrial machinery, the top roller bearings are the core transmission components, and their working performance is directly related to the operating efficiency and stability of the equipment.

[0003] Traditional roller bearing designs tend to favor one of two lubrication modes: either relying on a continuous oil supply to ensure adequate lubrication and reduce friction and wear; or using self-lubricating materials or structural designs to reduce maintenance frequency, which is suitable for occasions where regular oiling is difficult or there are special requirements for the environment. However, roller bearings with continuous oil supply have more stringent maintenance requirements. Any failure in the oil circuit may lead to insufficient lubrication, accelerated bearing wear, and even cause environmental pollution in some cases. Although self-lubricating roller bearings reduce maintenance requirements, their self-lubricating performance will gradually decline after long-term operation, especially under high load or extreme temperature conditions, and may not provide sufficient lubrication. Therefore, we propose a roller bearing structure that takes into account both oiling and non-oiling. Utility Model Content

[0024] The two spacers 107 and the two grooves 109 are staggered and distributed. The spacer 107 is located between the two deep groove ball bearings 104 . The top roller shell 101 is rotatably connected to the mounting sleeve 106 via the deep groove ball bearings 104 .

[0025] The fixing mechanism 2 includes a fixing seat 201, which has two arc grooves 208, and two balls 202 are slidably connected inside the arc groove 208. The inner wall of the fixing seat 201 is provided with a threaded groove 203, and the internal thread of the threaded groove 203 is connected to a bolt 204, a baffle 206 is fixedly connected to the bolt 204, and an annular groove 205 is provided on the bolt 204. Limiting grooves 207 are provided on both sides of the fixing seat 201.

[0026] The arc-shaped groove 208 passes through the surface of the fixing seat 201 and extends to the interior of the fixing seat 201. The two limit grooves 207 are staggered with each other, and the two limit grooves 207 are symmetrically distributed with the bolt 204 as the center. The size of the baffle 206 is larger than the size of the fixing seat 201. The ball 202 and the annular groove 205 are offset against each other. The size of the limit block 108 is adapted to the size of the limit groove 207. The limit block 108 is slidingly connected to the limit groove 207. The side of the ball 202 away from the bolt 204 is clamped with the groove 109, and the inner wall of the mounting sleeve 106 is slidingly connected to the surface of the fixing seat 201.

[0027] The leather roller mechanism 3 includes a core shaft 301, an aluminum sleeve 302 is sleeved on the core shaft 301, and a rubber sleeve 303 is sleeved on the aluminum sleeve 302. Fixing holes 304 are provided at both ends of the core shaft 301. The side of the fixing seat 201 away from the leather roller shell 101 is fixedly connected to the core shaft 301. The bolt 204 passes through the fixing seat 201 and extends to the inside of the fixing hole 304. The leather roller shell 101 and the core shaft 301 are rotatably connected. The sealing ring 103 is away from the deep groove ball bearing 104 and is abutted against the side of the core shaft 301. The deep groove ball bearing 104 is located between the baffle 206 and the core shaft 301.

[0028] Adopting the above solution: when working, the oil filling hole 102 faces upward, and the oil filling hole 102 is covered with a pressure shaft, but there is a gap for air to pass through, which is conducive to heat dissipation. When the drawing frame manufacturer supplies, a high-quality double-sided sealed deep groove ball bearing 104 is installed, and the textile user can use it like an oil-free roller. If the user really needs to periodically oil the roller, the double-sided sealed deep groove ball bearing 104 can be replaced with a single-sided sealed deep groove ball bearing 104, and they can be installed opposite to each other. Oil is periodically or continuously injected through the upper oil filling hole 102, so that the oil passes through the micropores 105 on the deep groove ball bearing 104 to lubricate the deep groove ball bearing 104;

[0029] During assembly, first put the bolt 204 into the interior of the leather roller shell 101, and assemble the two deep groove ball bearings 104 and the mounting sleeve 106. Then, after the assembled mounting sleeve 106 is put into the interior of the leather roller shell 101, the deep groove ball bearing 104 is away from the baffle 206, and the sealing ring 103 is clamped between the inner wall of the leather roller shell 101. At the same time, the hanging small shaft 110 is removed. Then, the limit block 108 inside the mounting sleeve 106 is aligned with the limit groove 207 on the fixed seat 201, and the assembled leather roller shell 101 is moved in the direction close to the core shaft 301 so that the mounting sleeve 106 is sleeved on the surface of the fixed seat 201. At this time, the two grooves 109 are respectively located at the two ball bearings 20 2, and the unthreaded portion of the bolt 204 is moved into the interior of the fixing seat 201. Then, the bolt 204 is rotated with a hexagonal wrench to threadably connect the bolt 204 with the threaded groove 203 until the baffle 206 abuts against the side of the fixing seat 201 away from the core shaft 301. During this process, the unthreaded portion of the bolt 204 squeezes the ball 202 so that the side of the ball 202 away from the bolt 204 abuts against the groove 109, fixing the mounting sleeve 106 to the surface of the fixing seat 201. At this time, the side of the roller shell 101 close to the core shaft 301 is clamped with the side surface of the core shaft 301, making it easy to install and remove the deep groove ball bearing 104.

[0030] At the same time, the positions of the two deep groove ball bearings 104 can be limited by the spacer sleeve 107, and the installation sleeve 106 is set between the deep groove ball bearing 104 and the fixed seat 201 to avoid frequent replacement of the deep groove ball bearing 104 causing wear on the fixed seat 201 and reducing the service life of the core shaft 301.

[0031] The working principle and usage process of the present invention are as follows: first, when assembling the device, the bolt 204 is first put into the interior of the leather roller shell 101, and the two deep groove ball bearings 104 are assembled between the mounting sleeve 106, and then the assembled mounting sleeve 106 is put into the interior of the leather roller shell 101, and the sealing ring 103 is clamped between the inner wall of the leather roller shell 101 when the deep groove ball bearing 104 is away from the baffle 206, and the hanging small shaft 110 is removed at the same time, and then the limiting block 108 inside the mounting sleeve 106 is aligned with the limiting groove 207 on the fixing seat 201, and the assembled leather roller shell 101 is moved in the direction close to the core shaft 301, so that the mounting sleeve 106 is sleeved on the surface of the fixing seat 201, and the two grooves 109 are respectively located at the two ball bearings. 202 are away from each other, and the unthreaded part of the bolt 204 is moved to the inside of the fixing seat 201, and then the bolt 204 is rotated with the hexagonal wrench to thread the bolt 204 into the threaded connection between the bolt 204 and the threaded groove 203 until the baffle 206 and the fixing seat 201 are against the side away from the core shaft 301. During this process, the unthreaded part of the bolt 204 squeezes the ball 202 so that the side of the ball 202 away from the bolt 204 is against the groove 109, and the mounting sleeve 106 is fixed to the surface of the fixing seat 201. At this time, the side of the roller shell 101 close to the core shaft 301 is clamped with the side of the core shaft 301. Finally, the hanging small shaft 110 is installed to complete the installation of the bearing. The disassembly is carried out in the opposite order to the installation.

[0032] During operation, the oil filling hole 102 faces upward, and a pressure shaft is covered on the oil filling hole 102, but there is a gap for air to pass through, which is conducive to heat dissipation. When supplied by the drawing frame manufacturer, a high-quality double-sided sealed deep groove ball bearing 104 is installed, and textile users can use it like an oil-free roller. If the user really needs to periodically oil the roller, the double-sided sealed deep groove ball bearing 104 can be changed to a single-sided sealed deep groove ball bearing 104, and installed relatively. Oil is periodically or continuously injected through the upper oil filling hole 102 to lubricate the deep groove ball bearing 104 through the micropores 105 on the deep groove ball bearing 104.
