Embodiment Construction

[0027] Embodiments of a bearing cage according to the present invention will hereinafter be described in detail with reference to the accompanying drawings. In the description of the drawings, the same or corresponding parts are denoted by the same numerals and symbols, and repeated descriptions will be omitted.

[0028] Figure 3a is a partial sectional view showing a bearing having a bearing cage according to the present invention. Such as Figure 3a As shown, the bearing is a double row roller bearing, and the rollers are tapered rollers. However, the bearing may be a single row roller bearing, and the rollers may be cylindrical rollers or the like. Bearings can be used in wind turbines. The bearing includes an inner ring 1 , an outer ring 2 , a plurality of rollers 3 and a bearing cage 4 . The inner ring 1 is located radially inside the outer ring 2 , and the bearing cage 4 is located between the inner ring 1 and the outer ring 2 . A plurality of rollers 3 are held o...

Abstract

The invention provides a bearing retainer. The bearing retainer (4) comprises: a first gasket (6) and a second gasket (8), which are located at two sides of the bearing retainer (4) in an axial direction, and a plurality of separation blocks (7) arranged between the first gasket (6) and the second gasket (8). Rollers of the bearing can be kept between the adjacent separation blocks (7). Opposite sides of the first gasket (6) and the second gasket (8) are provided with a first slideway (6.2) and a second slideway (8.2), and the separation blocks (7) can slide along the first slideway (6.2) and the second slideway (8.2). The invention further provides a bearing comprises the bearing retainer.

Description

technical field [0001] The present application relates to a bearing cage and a bearing with the bearing cage. Background technique [0002] Various cages are known for bearings, such as pinned cages and segmented cages. [0003] Figure 1a A double row roller bearing with a pin cage is shown, which comprises two inner rings 1 , an outer ring 2 , rollers 3 , bearing cage 4 and spacer rings 5 ​​. A bearing cage 4 as a pin cage is located between the inner ring 1 and the outer ring 2 , the rollers 3 are held on the pin cage, and the spacer ring 5 separates the two inner rings 1 . Figure 1b A perspective view of the pin cage is shown. The pin cage comprises a first washer 4.1, a second washer 4.3 and a pin 4.2 between the first washer 4.1 and the second washer 4.3. Each roller 3 has a central hole through which a pin 4.2 passes and is connected between the first washer 4.1 and the second washer 4.3. [0004] Figure 2a A double row roller bearing with a segmented cage is s...
