[0002] As an important component in bearing technology, cylindrical roller bearings have their background technology rooted in the continuous pursuit of efficiency and reliability of rotating machinery. Since the late 19th century, they have undergone multiple innovations in materials, design, and manufacturing processes. Their development history has witnessed the evolution from simple rolling elements to high-precision, high-performance bearings. Today, cylindrical roller bearings are widely used in various industrial fields such as mechanical manufacturing, automobiles, aerospace, and wind power equipment, covering numerous scenarios that require precise, high-speed, and heavy-load rotation.

[0003] The document with application number 201510014724.6 proposes a cylindrical roller bearing. The invention provides a cylindrical roller bearing, which includes: an inner ring; an outer ring located outside the inner ring in the radial direction of the cylindrical roller bearing; rollers located between the outer ring and the inner ring in the radial direction of the cylindrical roller bearing; and a cage also located between the outer ring and the inner ring in the radial direction of the cylindrical roller bearing and used to retain the rollers. The characteristic of the invention is that the cage is composed of multiple separate circular arc segments, which are arranged concentrically relative to the inner ring and the outer ring, and one roller is arranged between two adjacent circular arc segments. A first gap is provided between the outer ring and the circular arc segment, and a second gap is provided between the inner ring and the circular arc segment. The cylindrical roller bearing of the invention can improve the ability to withstand extreme impact loads without increasing the overall size of the bearing.

[0024] Secondly, the "one embodiment" or "embodiment" referred to here means that specific features, structures or characteristics can be included in at least one implementation of the utility model. In this specification, "in one embodiment" does not mean the same embodiment, nor is it an independent or alternative embodiment that excludes other embodiments.

[0025] Embodiment

[0026] Refer to Figs. 1-4 For the embodiment of the utility model, the embodiment provides a noise reduction type cylindrical roller bearing, which comprises,

[0027] The sleeve 101, the penetration hole 102 opened in the inner wall of the sleeve 101, the reserved groove 103 opened in the side wall of the sleeve 101, the mounting ring 104 movably connected to the inner wall of the sleeve 101, the vertical roller 105 movably connected to the inner wall of the mounting ring 104, the connecting assembly 106 arranged on the side wall of the sleeve 101, and the noise reduction assembly 107 arranged in the inner cavity of the sleeve 101.

[0028] Specifically, the connecting assembly 106 comprises a connecting sleeve 106a threadedly connected to the inner wall of the sleeve 101, and a connecting disc 106b fixedly installed on the inner wall of the connecting sleeve 106a. The connecting assembly 106 further comprises an inclined roller 106c movably installed on the inner wall of the connecting disc 106b, and a reserved opening 106d opened in the side wall of the connecting disc 106b.

[0029] Further, the connecting disc 106b cooperates with the inclined roller 106c. When the roller shaft is connected, the inclined roller 106c cooperates with the roller shaft to rotate, which can increase the area connected by the roller shaft and all the rotors, thereby reducing the stress area of the rotors and the sound generated by the friction of the rollers. The penetration hole 102 can intercept the lubricating oil added into the sleeve 101, so as to penetrate the lubricating oil onto the rollers during operation, thereby reducing the sound generated by the rotation of the rollers.

[0030] Preferably, the noise reduction assembly 107 comprises a support layer 107a fixedly connected to the inner cavity of the sleeve 101, and an adsorption layer 107b fixedly connected to the surface of the support layer 107a. The noise reduction assembly 107 further comprises a filling layer 107c fixedly connected to the surface of the adsorption layer 107b, and a connecting layer 107d fixedly connected to the side wall of the filling layer 107c. The support layer 107a is made of aluminum honeycomb plate material, the adsorption layer 107b is made of sponge material, the filling layer 107c is made of sound insulation cotton material, and the connecting layer 107d is made of glass wool material.

[0031] It should be noted that the support layer 107a made of aluminum honeycomb plate is arranged to absorb the sound generated during the operation of the device. The adsorption layer 107b made of sponge can absorb lubricating oil. During the operation of the device, the lubricating oil can be squeezed out to lubricate the rollers through the penetration hole 102. The filling layer 107c made of sound insulation cotton can absorb the sound generated by the rotation of the rollers at close range. The connecting layer 107d made of glass wool material can absorb noise while providing strong support for the rotation of the rotors.

[0032] In use, the inclined roller 106c in the connecting assembly 106 cooperates with the vertical roller 105 to increase the contact area between the roller shaft and the roller, reduce the force on the rotor, and reduce the noise generated by the friction of the roller. At the same time, the penetration hole 102 can trap lubricating oil, allowing it to gradually penetrate the roller during operation, further reducing noise. The noise reduction assembly 107 is made of different materials. The aluminum honeycomb plate support layer 107a absorbs operating sound. The sponge adsorption layer 107b absorbs and squeezes lubricating oil to lubricate the roller. The soundproof cotton filling layer 107c absorbs the sound of the roller rotating at close range. The glass wool connecting layer 107d absorbs noise and provides support for the rotation of the rotor, working together to reduce noise and improve operating efficiency.

[0033] In summary, through the cooperation of the inclined roller 106c and the vertical roller 105, the contact area between the roller shaft and the roller is increased, effectively dispersing the force on the rotor and significantly reducing the noise generated by friction. The design of the penetration hole 102 cleverly achieves continuous penetration of lubricating oil, providing long-lasting lubrication for the roller and further reducing noise and wear. The noise reduction assembly 107 is composed of aluminum honeycomb plates, sponges, soundproof cotton, and glass wool, forming a multi-layer soundproofing and lubrication system. The aluminum honeycomb plate support layer 107a effectively absorbs the sound of the device during operation. The sponge adsorption layer 107b not only absorbs lubricating oil but also squeezes out lubricating oil to lubricate the roller during operation. The soundproof cotton filling layer 107c absorbs the noise of the roller rotating at close range. The glass wool connecting layer 107d has a dual role, absorbing noise and providing a solid support for the stable rotation of the rotor. The precise cooperation and synergy between these parts achieve multiple beneficial effects of reducing noise, improving lubrication, and improving operating efficiency.
