Abstract
The utility model discloses a rolling bearing used in a fixed wheel of an irrigation gate, which is provided with an inner ring (4) and an outer ring (1), wherein a retainer (2) and a double-row roller (3) are arranged between the inner ring (4) and the outer ring (1), and the end surface of the double-row roller is a ball base surface. Both sides of a middle block edge (7) of the inner ring are in a circular arc shape, an oil tank (6) is arranged in the center line of the inner diameter of the inner ring (4), and an oil hole (5) is arranged in the oil tank (6). Because the end surface of the double-row roller is provided with the ball base surface and the double-row roller is matched with the middle block edge of the inner ring, which is in a circular arc shape, the condition that the end surface of a rolling body is in point contact with the middle block edge of the inner ring can be realized and the frictional force between the rolling body and the middle block edge of the inner ring is reduced. The oil groove and the oil hole are arranged on the center line of the inner ring, simultaneously, the size of the inner diameter of the retainer can be enlarged and the shape of a retainer pocket hole is optimized to realize the precise guide of the rolling body. The frictional force between the retainer and the block edge of the inner ring is reduced, and lubricating grease can successfully enter the inner part of the bearing.
Description
Affiliated technical field
The utility model belongs to a kind of rolling bearing, relates generally to a kind of water conservancy gate fixed wheel rolling bearing, and it is a kind of heavy duty, low friction double-row self-aligning roller bearing.
Background technique
At present, Chinese large-sized hydraulic engineering gate bearing of fixed wheel all adopts sliding bearing.Sliding bearing has advantages such as bearing capacity is big, reliability is high, the life-span is long, and still, the friction factor of sliding bearing is big, keying is dumb, has improved the hoisting capacity and the volume of starting device greatly, and therefore, the manufacture cost of complete equipment is higher.
Summary of the invention
The purpose of this utility model provides long service life, little, the flexible a kind of water conservancy gate fixed wheel rolling bearing of keying of friction factor.
The technological scheme that its technical problem that solves the utility model adopts is: have inner ring and outer ring, between inner ring and outer ring, be provided with retainer and biserial roller, the end face of biserial roller is the ball basal plane, the centre rib of inner ring is a circular arc, and the center line of inner ring internal diameter is provided with oil groove, is provided with oilhole in oil groove.
Described oilhole is six, is distributed on the oil groove.
As seen from the above,, match, can realize that the rolling element end face contacts with inner ring centre rib point, has reduced the frictional force of rolling element and inner ring centre rib with inner ring circular arc centre rib because the end face of biserial roller is set to the ball basal plane.Open oil groove and oilhole on the inner ring center line, the shape that strengthens retainer internal diameter size, optimization retainer pocket hole simultaneously realizes that rolling element accurately guides, and has both reduced the frictional force between retainer and the inner ring rib, makes lubricating grease can enter bearing inside smoothly again.The heavy duty that relates to, low friction double-row self-aligning roller bearing, remedied the deficiency of sliding bearing, have, characteristics such as greasy property is good, long service life, reliable smoothness of operation height, friction factor is little, keying is flexible, greatly reduce the hoisting capacity and the volume of starting device, therefore the manufacture cost that can save complete equipment.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model.
Among the figure: 1, outer ring, 2, retainer, 3, roller, 4, inner ring, 5, oilhole, 6 oil grooves, 7, the inner ring centre rib.
Embodiment
In conjunction with the accompanying drawings, specific embodiment of the utility model is described.
As shown in Figure 1: the utility model is used for the fixed wheel of water conservancy gate, comprise inner ring 4, outer ring 1, retainer 2 and biserial roller 3 are set between inner ring and outer ring, the middle part of inner ring 4 has centre rib 7, its both sides are arc-shaped structure, the end face of roller 3 is the ball basal plane, matches with the arc surface of centre rib.The center line of inner ring 4 internal diameters is provided with oil groove 6, is evenly equipped with six oilholes 5 on oil groove.
Claims (2)
1, a kind of water conservancy gate fixed wheel rolling bearing, has inner ring (4) and outer ring (1), between inner ring (4) and outer ring (1), be provided with retainer (2) and biserial roller (3), it is characterized in that: the end face of biserial roller is the ball basal plane, the both sides of the centre rib of inner ring (7) are circular arc, and the center line of inner ring (4) internal diameter is provided with oil groove (6), is provided with oilhole (5) in oil groove (6).
2, water conservancy gate fixed wheel rolling bearing according to claim 1, it is characterized in that: described oilhole (5) is six, is distributed on the oil groove.
