In the large-displacement motorcycle market, which enters a rapid development stage in recent years, in 2020, the yield and sales of motorcycles with displacement of more than 250ml (without 250 ml) is about 20.08 ten thousand, which is 13.32% higher than that of the motorcycles with displacement of more than 250ml, and is 14 times higher than that of the motorcycles with displacement of 2013 (1.3 ten thousand). From the total motorcycle market amount in China, the motorcycle with large discharge only accounts for about 3 percent, and still has huge development potential. With the continuous improvement of the income level of residents, the income groups of medium and high level are continuously expanded, and the future large-displacement motorcycle accounts for 10 percent of the total amount of the domestic motorcycle market.
With the rapid development of the large-displacement motorcycle, the bearing applied to the large-displacement motorcycle is also rapidly developed; since bearings for engines and transmissions of motorcycles are used under conditions of high temperature and high speed rotation in a foreign matter environment and large impact load, they are required to have high rigidity and high resistance to foreign matters.
Meanwhile, the engine and transmission of a large-displacement motorcycle are being reduced in size and weight, and the engine and transmission bearings of a motorcycle are also required to be reduced in size, weight, and life.
Most of the existing bearings used on the large-displacement motorcycles are deep groove ball bearings with a universal single-side RS sealing structure or cylindrical roller bearings with an external independent sealing structure as shown in the attached drawing 1, because the engine and the speed change device of the motorcycle have the requirements on the miniaturization and the light weight of the bearings, the traditional ball bearing load cannot meet the requirements, and no space is available for selecting larger deep groove ball bearings, the deep groove ball bearings need to be replaced by the cylindrical roller bearings with the same specification and external dimension to improve the bearing capacity and the service life, but the traditional cylindrical roller bearing structures are separable structures: at least one of the inner ring or the outer ring is a single rib or no rib, so that the inner ring or the outer ring can be separated from the roller. And all are not sealed, requiring an external independent seal structure. The cost of the engine and the speed changing device of the large-displacement motorcycle is increased, the occupied space is large, and the requirement of miniaturization and lightweight of the installation space cannot be met.
Meanwhile, the outer diameter of the outer ring of the traditional cylindrical roller bearing is in interference fit with the seat hole; when the bearing is installed in a large-displacement motorcycle engine and a speed change device, the outer diameter of the outer ring of the traditional cylindrical roller bearing is pressed into a seat hole and then sleeved on a shaft, and the inner diameter of the inner ring of the traditional cylindrical roller bearing is in clearance fit with a shaft neck, so that the risk of falling of the inner ring exists in the assembly process.

the utility model provides a sealed inseparable cylindrical roller bearing in area, has outer lane, inner circle and a plurality of cylindrical roller, cylindrical roller arranges between outer lane and inner circle, sets up the raceway respectively on inner circle and the outer lane, the outer lane has arranged bellied flange in raceway one side, and the opposite side is equipped with first mounting groove and arranges the lock ring at the inslot, outer lane flange side still is equipped with the second mounting groove, still has the sealing washer interference to install between second mounting groove and inner circle.
On the basis of the technical scheme, the two sides of the raceway of the inner ring are respectively provided with a first raised rib and a second raised rib, and the second raised ribs are matched with the outer ring ribs.
On the basis of the technical scheme, the width of the outer ring rib is larger than half of the difference between the width of the outer ring and the width of the cylindrical roller.
On the basis of the technical scheme, the width of the first rib of the inner ring is smaller than that of the second rib.
On the basis of the technical scheme, the lock ring is an annular elastic metal piece with a notch.
On the basis of the technical scheme, the cylindrical roller is further provided with a bearing retainer, and the bearing retainer is arranged on the inner side of a sealing ring at the flange of the outer ring.
On the basis of the technical scheme, the bearing retainer is made of copper materials, steel materials, alloy materials, engineering plastics or resin materials.
On the basis of the technical scheme, the bearing is further used for an engine and a speed changing device of a motorcycle.
The inseparable cylindrical roller bearing with the seal, provided by the invention, has the advantages that the built-in seal structure and the lock ring structure are adopted, the fatigue life is prolonged by one time and 8 times compared with a deep groove ball bearing with the same external dimension, and meanwhile, the inseparable cylindrical roller bearing with the seal has good sealing performance, avoids leakage of lubricating oil of a large-displacement motorcycle engine gearbox, and is convenient for realizing miniaturization and light weight of the large-displacement motorcycle engine gearbox.
