The speed increaser of the wind turbine is installed at a high place, and maintenance is very difficult, so the life and reliability of the speed increaser bearing are very high. In recent years, wind turbines have become larger and larger, and in order to reduce the load on the tower, attempts have been made to reduce the size and weight of the generator nacelle. Therefore, the demand for small bearings with high load capacity has further increased. The high-load-capacity cylindrical roller bearing developed to meet this demand uses rolling element spacers instead of the cage, so the load capacity is increased without damaging the rotational performance, and the rated life is more than 1.5 times that of the original product.
High Load Capacity Cylindrical Roller Bearing Structure and Features of High Load Capacity Cylindrical Roller Bearing: The new product is designed with a spacer made of resin material between the rollers, which can prevent the rollers from contacting each other. In addition, on the spacer rings that are separated from each other, the tension caused by the clutch and dispersion of the rollers does not work, so the thickness can be reduced, and the size and number of the rollers can be increased.
Structural comparison of new products and original products By comparing the performance of new products and original products, the high load capacity cylindrical roller bearings of new products have the following advantages:
1. The size and number of long-life rollers are optimized to increase the load capacity, and the rated life of the bearing is more than 1.5 times that of the bearing with the cage with the same size as the original.
2. The high speed prevents the rollers from contacting each other in the full complement roller bearing. It is better to optimize the shape of the spacer and the guiding method to achieve the same allowable rotation speed and friction resistance as the bearing with a cage. Injury.
3. Operability Even if the inner ring is removed without causing the rollers to fall off, the inner ring and outer ring components can be installed separately, making it easier to install on the machine.
