[0002] New energy vehicles refer to vehicles that use unconventional vehicle fuels as their power source (or use conventional vehicle fuels and adopt new on-board power devices), and integrate advanced technologies in vehicle power control and drive to form vehicles with advanced technical principles, new technologies, and new structures. New energy vehicles drive the vehicle through electric motors, and bearings are installed on the motors. Bearings are parts used to support the shaft. They can guide the rotation of the shaft and also withstand idling parts on the shaft. Chinese patent application number 201821069034.6 discloses a new energy vehicle bearing. It can be seen that the content describes a new energy vehicle bearing.

[0003] When the existing bearings for new energy vehicles are in use, the rollers will roll in contact with the outer wall of the inner ring and the inner wall of the outer ring. Over time, the outer wall of the inner ring and the inner wall of the outer ring will be worn, affecting the use time of the inner ring and the outer ring and reducing the service life of the bearing. For this reason, we propose a bearing for new energy vehicles. Utility Model Content

[0004] The purpose of the utility model is to provide a bearing for new energy vehicles, so as to solve the problem in the above-mentioned background technology that when the existing bearings for new energy vehicles are in use, the rollers roll in contact with the outer wall of the inner ring and the inner wall of the outer ring, which will cause wear to the outer wall of the inner ring and the inner wall of the outer ring over time.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a bearing for new energy vehicles, comprising an outer ring and an inner ring, a plurality of groups of rollers are arranged between the outer ring and the inner ring, a protection mechanism is arranged inside the inner ring, the protection mechanism comprises an oil storage tank and an oil-core cotton thread, a connecting tube is fixedly arranged inside the inner ring, a sponge column is fixedly arranged inside the connecting tube, the bottom of the sponge column can contact the outer wall of the roller, and the end of the oil-core cotton thread is fixedly connected to the top of the sponge column.

[0006] Preferably, a baffle is fixedly disposed inside the oil storage tank, and a rubber sealing tube is fixedly disposed inside the baffle.

[0007] Preferably, the end of the oil-core cotton thread passes through the interior of the rubber sealing tube, and an oil filling hole is opened on the front side of the inner ring, and the oil filling hole is connected to the oil storage tank.

[0008] Preferably, a rubber column plug is provided inside the oil filling hole, and the oil storage tank is communicated with the connecting pipe.

[0009] Preferably, the oil storage tank is an arc-shaped structure.

[0010] Preferably, a limit plate is fixedly provided on the front side of the rubber column plug, and the limit plate is fixedly connected to the inner ring by two sets of screws.

[0011] Preferably, a retaining frame is provided outside the roller, and the outer ring and the inner ring are annular structures when viewed from the front.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] (1) The utility model guides the lubricating oil in the oil storage tank to the sponge column through the oil core cotton thread. When the outer wall of the roller contacts the sponge column during rolling, the lubricating oil on the sponge column sticks to the outer wall of the roller. When the roller rolls, it lubricates the outer wall of the inner ring and the inner wall of the outer ring, thereby reducing the wear between the outer wall of the inner ring and the inner wall of the outer ring, increasing the service life of the inner ring and the outer ring, and thus increasing the service life of the bearing.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-Figure 4 The utility model provides a technical solution: a bearing for new energy vehicles, including an outer ring 100 and an inner ring 103, multiple groups of rollers 101 are arranged between the outer ring 100 and the inner ring 103, and the rollers 101 can roll between the inner ring 103 and the outer ring 100 when in use, and a protection mechanism is arranged inside the inner ring 103, and the protection mechanism includes an oil storage tank 202 and an oil core cotton thread 203, and a connecting pipe 206 is fixedly arranged inside the inner ring 103, and the connecting pipe 206 is fixedly arranged inside There is a sponge column 205, which can absorb lubricating oil when in use, and the bottom of the sponge column 205 can contact the outer wall of the roller 101. The end of the oil core cotton thread 203 is fixedly connected to the top of the sponge column 205. A baffle 204 is fixedly arranged inside the oil storage tank 202, and a rubber sealing tube 207 is fixedly arranged inside the baffle 204. When in use, the oil core cotton thread 203 is fixed in the rubber sealing tube 207, and the end of the oil core cotton thread 203 passes through the rubber sealing tube 207. 7, an oil filling hole 200 is provided on the front of the inner ring 103, and lubricating oil can be injected into the oil storage tank 202 through the oil filling hole 200 during use. The oil filling hole 200 is connected with the oil storage tank 202, and a rubber column plug 201 is provided inside the oil filling hole 200, and the oil storage tank 202 is connected with the connecting pipe 206. The oil storage tank 202 is an arc-shaped structure, and the designed protection mechanism facilitates the injection of lubricating oil into the oil storage tank 202 during use, and the oil storage tank 202 is filled with oil through the oil core cotton thread 203. The lubricating oil in the groove 202 is guided to the sponge column 205. When the outer wall of the roller 101 contacts the sponge column 205 during rolling, the lubricating oil on the sponge column 205 is attached to the outer wall of the roller 101. When the roller 101 rolls, it lubricates the outer wall of the inner ring 103 and the inner wall of the outer ring 100, thereby reducing the wear between the outer wall of the inner ring 103 and the inner wall of the outer ring 100, thereby increasing the service life of the inner ring 103 and the outer ring 100, and thus increasing the service life of the bearing.
