Description

Technical Field

[0001] The utility model relates to the field of bearings, in particular to a corrosion-resistant bearing. Background Art

[0002] In the field of floor scrubber technology, the corrosion resistance of bearings has always been a key factor affecting equipment performance and service life. In the floor scrubber industry, bearings are key components, and their performance directly affects the overall operation of the equipment.

[0003] Traditional bearing designs are often unable to resist the erosion of liquids and chemicals during the cleaning process, and often exhibit weak corrosion resistance, which causes the bearings to be easily damaged and have a short service life. This not only increases the maintenance cost of the equipment, but also affects the working efficiency of the floor scrubber. Therefore, developing a bearing with excellent corrosion resistance has become an important direction for the development of floor scrubber technology.

[0004] After extensive searching, it was found that the prior art publication number is CN212318546U, which discloses a corrosion-resistant bearing ring. A reinforcing rib is arranged in the central annular groove, and the reinforcing rib reinforces the internal structure of the bearing ring body, so as to avoid the setting of the central annular groove affecting the internal structural strength of the bearing ring body, thereby solving the problems of poor corrosion resistance, easy corrosion and rust, limited use conditions, frequent replacement and high use cost of the bearing in the prior art.

[0005] Therefore, based on the above search and in combination with the prior art, there are still some problems in the use of the above equipment. During the process of oiling the internal raceway, because there is no mechanism on both sides of the raceway to prevent the lubricating oil from overflowing, during the process of injecting the lubricating oil into the interior, the internal lubricating oil is easily thrown out of the interior of the raceway as it rotates, and splashes into the interior of the bearing sleeve, causing corrosion to the internal surface.

Both sides of each connecting frame 19 are connected to another connecting frame 19 by connecting rods. A rotatable sliding wheel 20 is arranged at the center of the connecting frame 19.

The limiting ring 2 is provided with a second retaining groove 17 on the surface of the side close to the bearing sleeve 1, which is matched with the retaining ring 6 on the side of the inner ring 4. A second retaining ring 18 is fixedly installed at the center of the limiting ring 2, which is opposite to the first retaining ring 12 and covers the other side surface of the rolling ring 8.

[0026] The oil filling assembly includes: a nozzle plug 3, which is located on the upper surface of the bearing sleeve 1, and a nozzle 9 is provided on the bottom surface of the nozzle plug 3. The nozzle plug 3 can be inserted and removed from the nozzle 9.

[0027] In this embodiment, a corrosion-resistant bearing in this solution is mainly composed of a bearing sleeve, a rotating mechanism, an isolation mechanism and an oil injection assembly, and each part works together to achieve corrosion resistance and efficient rotation of the bearing;

[0028] The core of the rotating mechanism is the rolling ring, which is composed of multiple connecting rods and connecting frames. These connecting rods and connecting frames are connected to each other to form a ring structure. A sliding wheel is installed in the center of each connecting frame, which enables the entire rolling ring to roll freely inside the bearing sleeve. The sponge block on the upper surface of the connecting rod plays a role in absorbing and applying lubricating oil. When the bearing rotates, the sponge block can evenly apply the lubricating oil to the surface of the rolling ring, reducing friction and improving rotation efficiency.

[0029] The isolation mechanism is designed to prevent the lubricating oil inside the bearing from overflowing or external liquid from invading the inside of the bearing. It is mainly composed of a limiting sleeve, a water absorption sleeve, a first baffle ring, a sliding ring and an inner water absorption ring.

[0030] The water absorption sleeve on the surface of the limiting sleeve can absorb external liquid to prevent it from entering the bearing. At the same time, the limiting sleeve cooperates with the clamping ring on the bearing sleeve through the first clamping groove and is fixed to one side of the bearing sleeve. The sliding ring cooperates with the slideway groove in the bearing sleeve so that the limiting sleeve can slide inside the bearing sleeve but does not separate. The inner water absorption ring absorbs the liquid that has entered the bearing sleeve to keep the inside of the bearing dry.

[0031] The setting of the limiting ring and the second baffle ring works together with the first baffle ring to completely cover both sides of the rolling ring, further preventing liquid from invading, and preventing the internal lubricating oil from overflowing and flowing to the inner side of the bearing sleeve to cause corrosion to the inner side. The limiting ring cooperates with the clamping ring on the inner ring through the second clamping groove, and is ensured to be in the correct position through the cooperation of the limiting plate and the limiting groove;

[0032] The oil injection assembly is responsible for injecting lubricating oil into the bearing to keep the bearing in a lubricated state. The oil injection assembly mainly includes a nozzle plug and a nozzle. The nozzle plug is located on the upper surface of the bearing sleeve. The pluggable design allows the user to easily inject lubricating oil into the bearing through the nozzle. The lubricating oil enters the bearing sleeve through the nozzle, and then flows into the annular groove through the oil outlet hole, and finally lubricates the surface of the rolling ring.

[0033] The outer surface of the bearing sleeve is wrapped with a corrosion-resistant layer of polyurethane material, which can effectively prevent the corrosion of the bearing by external liquids. The polyurethane material has excellent corrosion resistance and oil resistance, which can keep the bearing intact for a long time and extend the service life of the bearing.

Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
