During operation, because the surface of the inner ring 1 of the liquid filling port 41 is provided with threads, the inner ring is convenient to be matched with the first sealing plug 42, when the first sealing plug 42 needs to be disassembled, the first sealing plug 42 is rotated for disassembling, then the inflowing lubricant impacts the scraping ring 6 when flowing in the lubricating cavity 4, so that the scraping ring 6 rotates, and meanwhile, the scraping blade 61 on the scraping ring 6 scrapes the inner wall of the lubricating cavity 4, so that the residual and attached old lubricant is scraped off, and the residual and attached old lubricant flows out under the action of the flowing new lubricant; the surface of the outer ring 2 of the scraper 61 is in contact with the inner wall of the lubricating cavity 4, so that the scraper ring 6 is limited, the scraper ring 6 rotates along an annular stable motion track without jumping up and down to a large extent, when the first sealing plug 42 is installed, the bottom of the downward-moving first sealing plug 42 is attracted by a magnet, so that the fixing holes 63 which are possibly deviated are automatically adjusted and matched with each other to be embedded into the fixing holes 63, the scraper ring 6 is limited and does not rotate any more, and the scraper ring 6 cannot rotate due to rotation in the working process of the bearing to cause vibration of the bearing; the installation of scraping ring 5 needs before the ring that constitutes lubrication chamber 4 is installed to scraping ring 5 can obtain complete scraping ring 5 through the same part combination more than two equally, and the smooth installation in lubrication chamber 4 of scraping ring 5 of being convenient for is followed and is installed the ring again, realizes installing scraping ring 5 in lubrication chamber 4's inside smoothly.
As a specific embodiment of the present application, the rolling channel 5 is nested with the sealing rings 7 at the positions close to the upper and lower surfaces of the bearing, so as to improve the sealing degree of the rolling channel 5.
When the transmission bearing works, when lubricant flows in, the lubricant does not pass to the outer ring 2 part and flows out from the gap part due to the gap between the inner ring 1 and the outer ring 2 on the transmission bearing, so that the detachable sealing ring 7 is arranged, the flowing-in lubricant is guaranteed to be limited and only flows out through the liquid outlet 22, and the utilization rate of the lubricant is improved; in a closed environment, the accumulated lubricant rapidly flows under the action of pressure to further flush the interior of the bearing and take away old lubricant and debris generated by abrasion of the rolling body 3; the sealing ring 7 is also detachable, can be smoothly detached when not needed, is flexibly applied and improves the practicability.
On the other hand of the embodiment of this application provides a shaft coupling, including foretell new energy automobile drive bearing, shaft coupling body and bearing flange in addition, drive bearing installs inside the bearing flange, and the bearing flange is installed on the shaft coupling body. Install on new energy automobile, at the in-process of transmission power, through the transmission bearing who installs this application setting, improve lubricated effect, reduce and maintain the clearance time.
In summary, the specific working principle of the invention is as follows:
according to the invention, the tapered chip storage grooves 5 are arranged in the ball grooves 4, so that the angle formed between the side walls of the chip storage grooves 5 is an obtuse angle, the direct contact area with the balls 3 can be further reduced, and the friction resistance of the balls 3 in the rotating process can be reduced.
Furthermore, the conical chip storage groove 5 forms a triangular-like area on the contact part with the ball 3, so that abrasion debris generated by the ball 3 in the high-strength working process can be collected in the area in a concentrated manner, the abrasion debris is not in direct contact with the ball 3, the friction resistance of the ball 3 in the working process is further reduced, and the purpose of improving the working efficiency of the bearing is achieved.
Further, the contact gap region between the chip pocket 5 and the ball 3 is divided into a plurality of small regions by the plurality of cleaning members 63 uniformly distributed in the chip pocket 5. When the wear debris gets into the clearance between the cleaning piece 63, because receive the limiting displacement of cleaning piece 63, can avoid the wear debris to concentrate in the clearance and contact ball 3 after and lead to increasing its frictional resistance.
Further, by serially connecting a plurality of cleaning pieces 63 through the cleaning pull ropes 62, two cleaning pull ropes 62 are arranged in the same chip storage groove 5, and each cleaning pull rope 62 is distributed in a semi-annular shape in the chip storage groove 5. One end of the cleaning pull rope is arranged at the impurity outlet 61, and the other end of the cleaning pull rope is arranged in the chip storage groove 5 and is positioned at the position with the largest distance from the impurity outlet 61, so that when two cleaning pull ropes 62 are pulled at the impurity outlet 61, the two cleaning pull ropes 62 are pulled out, and the cleaning piece 63 is driven to move through the impurity outlet 61 to enter the outside. In the process that the cleaning pieces 63 move, the cleaning pieces 63 scrape the inner parts of the chip storage grooves 5, abrasion debris with gaps among the cleaning pieces 63 is cleaned out, and then the cleaning piece 63 body is cleaned. After cleaning, the cleaning cord 62 is returned by the elastic repulsive force of the cleaning cord 62, and the function of stabilizing the debris is exerted again.
Furthermore, in the working process, the inner ring 2 part of the bearing and the matched shaft part rotate, so that the ball 3 rotates, abrasion debris is mainly concentrated inside the chip storage groove 5 of the outer ring 1 under the centrifugal action, the impurity removing port is positioned on the outer side surface of the outer ring 1, and the debris can be cleaned without disassembling the bearing; the impurity outlet 61 of the chip storage groove 5 on the inner ring 2 is positioned on the inner side surface of the inner ring 2 and is contacted with the part matched with the shaft, so that the inner ring needs to be disassembled for cleaning, but the accumulation of chips is relatively less, so that the cleaning period is longer; through the effect of clean stay cord 62 cooperation cleaning member 63, can realize the clearance to the inside accumulation piece of bearing under the condition that need not wholly decompose the bearing, reduce the degree of difficulty and the time that the bearing was maintained, improve the work efficiency of bearing.
Further, the cleaning pieces 63 in the chip storage grooves 5 are in contact with the side walls and play a skeleton supporting role in high-strength work, so that the load of a part of the bearing is borne, and the overall strength of the bearing is improved.
The front, the back, the left, the right, the upper and the lower are all based on figure 1 in the attached drawings of the specification, according to the standard of the observation angle of a person, the side of the device facing an observer is defined as the front, the left side of the observer is defined as the left, and so on.
