Description

Technical Field

[0001] This utility model relates to the field of lithium-ion battery technology, specifically to a novel high-sealing transmission device. Background Technology

[0002] In the rapid development of new energy, cylindrical lithium-ion batteries have become the primary choice for many industries such as automobiles and power tools. One step in the production of cylindrical batteries is cleaning. The main function of the cleaning machine is to remove dirt and residual electrolyte from the battery surface, and cleaning with plasma water effectively prevents the battery from rusting.

[0003] The cleaning machine works by rotating the battery under the pull of a chain. Brushes and high-pressure spray work together to clean the entire battery (4 sets of side brushes and 2 sets of end brushes), achieving thorough cleaning. The next station performs further fine washing, followed by air cutting and drying. The brush rotation is achieved by the cooperation of the brush shaft and bearing housing. The brushes are located at the tail end of the brush shaft. Because the bearing housing operates in a humid environment for extended periods, it rusts quickly and has a short lifespan. Rusting of the bearings can cause the brushes to swing excessively, resulting in incomplete cleaning or battery accumulation on the chain. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a novel high-sealing transmission device for use in battery cleaning machines, thereby avoiding contact between the bearing and external water vapor or steam, improving the service life of the bearing, and ensuring the cleaning effect on the battery.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a novel high-sealing transmission device, including a bearing mounting seat and a transmission shaft. The bearing mounting seat has a shaft hole, and bearing cavities are provided at both ends of the shaft hole. Each bearing cavity contains a bearing and a bearing cover. The bearing cover is connected to the bearing mounting seat and fixes the bearing to the bearing cavity. A shaft seal is provided on the bearing cover. The transmission shaft passes through the shaft hole and the shaft seal and connects to each bearing. The bearing mounting seat also has an oil injection hole, which communicates with each bearing cavity through the shaft hole. The oil injection hole is equipped with an oil nozzle. The transmission shaft passes through the shaft hole and connects to the bearings in the two bearing cavities. Each bearing cavity is sealed by a bearing cover. A waterproof seal is achieved between the transmission shaft and the bearing cover through the shaft seal. The bearing mounting seat has an oil injection hole, which communicates with the two bearing cavities through the shaft hole to facilitate oiling of the two bearings.

[0006] As an optional technical solution, the bearing cover includes a limiting cylinder. A limiting end cap is provided at one end of the limiting cylinder, which is located inside the bearing cavity and abuts against the bearing. An installation end cap is provided at the other end of the limiting cylinder, located outside the bearing cavity and connected to the outer end face of the bearing mounting seat. Both the limiting end cap and the installation end cap are provided with drive shaft clearance holes. A shaft seal is located inside the limiting cylinder. The bearing cover not only covers the bearing cavity but also limits the bearing's position.

[0007] As an optional technical solution, the bottom of the bearing mounting base is provided with a connecting base, which has several connecting holes. Using the connecting holes on the connecting base, the bearing mounting base can be installed into a designated position on the cleaning machine.

[0008] As an optional technical solution, the mounting hole is a waist hole.

[0009] As an optional technical solution, the oil filling hole is located at the top of the bearing mounting base.

[0010] As an optional technical solution, the drive shaft is provided with a transmission connection part and / or a brush mounting part outside the bearing mounting seat.

[0011] Compared with the prior art, the present invention has the following advantages: The transmission device of the present invention uses a bearing cover, shaft seal and transmission shaft to isolate the bearing cavity from the outside, effectively preventing water or moisture used for battery cleaning from entering the bearing cavity and affecting the service life of the bearing; the oil injection hole allows grease to be added to the two bearings, which not only lubricates the bearings, but also further isolates the bearings from moisture, preventing the bearings from rusting and shortening their service life, and also preventing the brush shaft of the cleaning machine from deforming due to bearing rusting and deformation, which would affect the cleaning efficiency of the battery, thus ensuring the cleaning effect of the battery; the device has good sealing performance, which is conducive to the use of the related structure of the device in water or other harsh and humid environments.

Example

[0017] Please see Figure 1 and Figure 2 A novel high-sealing transmission device includes a bearing mounting base 1 and a transmission shaft 2. The bearing mounting base has a shaft hole inside, which penetrates two opposite end faces of the bearing mounting base to allow the transmission shaft 2 to pass through. Bearing cavities are provided on both opposite end faces of the bearing mounting base. The two bearing cavities are located at the two ends of the bearing and are connected to the shaft hole. The bearing cavities are used to install bearings 3. After the bearings 3 are installed in the bearing cavities, the bearing cover 4 is connected to the bearing mounting base 1 and fixes the position of the bearings 3. The transmission shaft 2 is the brush shaft of the battery cleaning machine. The transmission shaft 2 passes through the shaft hole and is connected to the bearings 3 in the two bearing cavities. The transmission shaft 2 has a transmission connection part and / or a brush mounting part on the outside of the bearing mounting base. The transmission connection part is used to connect with the drive device so that the drive device can drive the brush shaft to rotate. The brush mounting part is used to install the brush.

[0018] The bearing cover 4 includes a limiting cylinder, with a limiting end cap at one end and a mounting end cap at the other end. The limiting cylinder extends into the bearing cavity, while the mounting end cap is located outside the bearing cavity and connected to the outer end face of the bearing housing via bolts, welding, riveting, or other connection methods. The limiting end cap is located inside the bearing cavity and engages with the bearing 3 to axially limit the position of the bearing 3. Both the bearing end cap and the mounting end cap have clearance holes for the drive shaft 2 to pass through.

[0019] The bearing cover 4 is also provided with a shaft seal 5, which is located inside the limiting cylinder. When the drive shaft 2 is installed on the bearing mounting seat 1, the drive shaft 2 passes through the shaft seal 5 and the outer end face of the drive shaft 2 mates with the shaft seal 5.

[0020] Optionally, the bearing mounting base 1 has a connecting base 7 at its bottom. The bearing mounting base 1 and the connecting base 7 can be an integral structure. The connecting base 7 has several connecting holes 8. Through the connecting holes 8 and connecting components such as bolts, the bearing mounting base 1 can be installed in a designated position on the cleaning machine. To facilitate the adjustment of the position of the bearing mounting base 1, the mounting holes are preferably oblong holes.

[0021] The bearing mounting base 1 is provided with an oil injection hole, which communicates with the shaft hole and, through the shaft hole, with each bearing cavity. The oil injection hole is equipped with an oil nozzle 6, which allows for simultaneous oiling of two bearings, thus improving the service life of the bearings. The oil injection hole can be located on the top of the bearing mounting base 1 for easy periodic oiling by the operator.

[0022] The transmission device of this utility model, by using bearing cover 4 and shaft seal 5, can effectively prevent water or moisture from entering the bearing cavity during battery cleaning and causing the bearing to rust. It can also periodically inject grease through the oil injection hole to lubricate the bearing. Moreover, the injected grease can further block the bearing from contacting external moisture, thus maximizing the service life of the bearing.
