Description

Technical Field

[0001] This utility model belongs to the field of bearing technology, and specifically relates to maintenance-free bearings for textile machinery. Background Technology

[0002] The existing textile machinery bearings generally use traditional liquid grease, which has the following drawbacks: First, grease leakage and contamination are prone to occur in high humidity and dusty environments; second, foreign matter intrusion leads to lubrication failure and accelerated bearing wear; third, lubrication performance deteriorates after long-term operation, requiring frequent shutdowns for maintenance; fourth, moisture erosion causes rust, reducing bearing life. Traditional mechanical bearings cannot meet both dust prevention and heat dissipation requirements, and grease replacement costs are high. Utility Model Content

[0003] The purpose of this invention is to provide maintenance-free bearings for textile machinery, which have the advantages of good dustproof and heat dissipation effects.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a maintenance-free bearing for textile machinery, comprising an outer ring of the bearing and an inner ring of the bearing disposed inside the outer ring of the bearing, wherein a plurality of balls are disposed between the inner ring of the bearing and the outer ring of the bearing.

[0005] A plastic oil seat is provided between the outer ring and the inner ring of the bearing. The plastic oil seat is U-shaped and the ball is located inside the U-shaped groove of the plastic oil seat. The plastic oil seat is made of a high molecular polymer material that can fully absorb lubricating oil.

[0006] The above technical solution involves a polymer material adsorbing saturated lubricating oil to form a plastic oil seat. This plastic oil seat has a certain viscosity and adhesion, which can fill the gaps inside the bearing, preventing external dust, moisture, and impurities from entering and providing a good sealing effect. Furthermore, under stress, the adsorbed grease can seep out of the plastic oil seat during operation, and when stationary, the grease is drawn back to the temporal part of the plastic oil seat, achieving solid-liquid two-phase lubrication. An installation groove is provided on the outer surface of the bearing inner ring, and a heat-conducting block is installed inside the installation groove. This allows the heat-conducting block to contact the inside of the bearing, and through the heat conduction effect of the heat-conducting block, heat exchange occurs with the external ring, reducing the internal temperature of the bearing and ensuring its service life.

[0007] The present invention is further configured such that a plurality of mounting grooves are equidistantly provided on the outer surface of the inner ring of the bearing, and heat-conducting blocks are symmetrically slidably connected inside the mounting grooves, and limit bolts are threadedly connected between two heat-conducting blocks.

[0008] By adopting the above technical solution, when the balls move inside the bearing, they can come into contact with the heat-conducting block, and the external temperature can be exchanged with the internal temperature of the bearing through the heat-conducting block, thereby reducing the heat inside the bearing and ensuring the service life of the bearing.

[0009] The present invention is further configured such that the plurality of balls are arranged in a ring at equal intervals in the circumferential direction, and the plastic oil seat is internally fitted with a retainer that is slidably connected to the balls.

[0010] The above technical solution is adopted to slide and limit the movement of the ball bearings inside the plastic oil seat.

[0011] The present invention is further configured such that sealing discs are symmetrically engaged between the outer ring and the inner ring of the bearing.

[0012] The above technical solution is adopted to prevent dust from entering the gap between the outer ring and the inner ring of the bearing.

[0013] The present invention is further configured such that the other end of the limiting bolt is threadedly connected to a limiting nut.

[0014] The above technical solution improves the stability of the two heat-conducting blocks fixed inside the mounting groove.

[0015] The present invention is further configured such that the inner ring of the bearing and the side of the heat-conducting block near the ball are both arc surfaces.

[0016] The above technical solution facilitates the rotation of the ball bearings.

[0017] In summary, this utility model has the following beneficial effects:

[0018] 1. This utility model forms a plastic oil seat by adsorbing saturated lubricating oil onto a polymer material. The plastic oil seat has a certain viscosity and adhesion, which can fill the gap inside the bearing and prevent external dust, moisture and impurities from entering, thus playing a good sealing role. Furthermore, under stress, the adsorbed grease can be lubricated and seeped out of the plastic oil seat when it is in operation, and when it is at rest, the grease is drawn back to the temporal part of the plastic oil seat, thus achieving solid-liquid two-phase lubrication.

[0019] 2. This utility model has an installation groove on the outer surface of the inner ring of the bearing, and a heat-conducting block is installed inside the installation groove. The heat-conducting block can contact the inside of the bearing, and through the heat conduction effect of the heat-conducting block, heat exchange with the external ring can be carried out, which can reduce the internal temperature of the bearing and ensure the service life of the bearing.

[0024] The present invention will be further described in detail below with reference to the accompanying drawings.

[0025] Example 1: Reference Figure 1 , Figure 2 and Figure 3 A maintenance-free bearing for textile machinery includes an outer ring 1 and an inner ring 2 disposed inside the outer ring 1. The bearing is characterized by: a plurality of balls 3 disposed between the inner ring 2 and the outer ring 1; and a plastic oil seat 4 disposed between the outer ring 1 and the inner ring 2. The plastic oil seat 4 is U-shaped, with the balls 3 positioned inside the U-shaped groove of the plastic oil seat 4. The plastic oil seat 4 is made of a high-molecular polymer material that fully absorbs lubricating oil. The plastic oil seat 4, made of high-molecular polymer material with a microporous structure, absorbs lubricating oil through these micropores until saturation. The plastic oil seat 4 has a certain viscosity and adhesiveness, capable of filling the gaps inside the bearing, preventing external dust, moisture, and impurities from entering, thus providing a good sealing effect. Furthermore, during operation, the plastic oil seat 4 can cause the absorbed grease to seep out under stress, and when stationary, the grease is drawn back to the temporal part of the plastic oil seat 4, achieving solid-liquid dual-phase lubrication.

[0026] Furthermore, multiple balls 3 are arranged in a ring at equal intervals in the circumferential direction, and a retainer 8 is inserted inside the plastic body oil seat 4 and is slidably connected to the balls 3. By setting the retainer 8, the movement of the balls 3 inside the plastic body oil seat 4 is slidably limited.

[0027] Furthermore, a sealing disc 9 is symmetrically engaged between the outer ring 1 and the inner ring 2 of the bearing. By setting the sealing disc 9, dust is prevented from entering the gap between the outer ring 1 and the inner ring 2 of the bearing.

[0028] Brief description of the usage process: The plastic oil seat 4, which is formed by fully adsorbing saturated lubricating oil into a polymer material to fill the gap between the bearing ball 3 and the raceway, can fill the gap between the ball 3 and the raceway inside the bearing. When in operation, the plastic oil seat 4 can lubricate and seep out the adsorbed grease under stress. When at rest, the grease is drawn back to the temporal part of the plastic oil seat 4 to achieve solid-liquid two-phase lubrication.

[0029] Example 2: Reference Figure 1 , Figure 2and Figure 3 The maintenance-free bearing for textile machinery has multiple mounting grooves 5 evenly spaced on the outer surface of the inner ring 2. Heat-conducting blocks 6 are symmetrically slidably connected inside the mounting grooves 5. Limit bolts 7 are threaded between two heat-conducting blocks 6. The mounting grooves 5 on the outer surface of the inner ring 2 allow the heat-conducting blocks 6 to contact the inside of the bearing. Through the heat conduction effect of the heat-conducting blocks 6, heat exchange occurs with the external environment, reducing the internal temperature of the bearing and ensuring its service life.

[0030] Furthermore, the other end of the limit bolt 7 is threadedly connected to a limit nut 10. By setting the limit nut 10, the stability of the two heat-conducting blocks 6 fixed inside the mounting groove 5 is improved.

[0031] Furthermore, the inner ring 2 of the bearing and the heat-conducting block 6 are both curved surfaces near the ball 3. By setting the inner ring 2 of the bearing and the heat-conducting block 6 to be curved surfaces near the ball 3, it is convenient for the ball 3 to rotate.

[0032] Brief description of usage: When the bearing generates high temperature during operation, the heat-conducting block 6 facilitates heat exchange between the external temperature and the internal temperature of the bearing, reducing the heat inside the bearing and ensuring its service life.

[0033] It should be noted that parts have a lifespan and can be replaced during regular maintenance when they no longer meet performance requirements. Deterioration in performance due to prolonged use of parts is not a design defect of this application.
