Abstract
The utility model belongs to the technical field of bearing and relates to a biserial self-aligning roller bearing which comprises a bearing outer ring, a bearing inner ring, an entity retainer and a roller. A lube groove and a lube hole are arranged on the bearing inner ring. The relevant bearing axis of the two circular arc bus bars ball races of the bearing inner ring declines to form an angle a of 13-15 DEG. The beneficial effect of the utility model is that the lube hole plays a role in lubricating effect during the using of the bearing without burning, decorticating and rust-eaten phenomena.
Description
Technical field
The utility model belongs to technical field of bearings, especially a kind of double-row self-aligning roller bearing.
Background technique
Selfaligning roller bearing is a key state project---the key water control project at the Three Gorges on the Yangtze River auxiliary products, be used for dam ship lock maintenance gate, and be the key position of water-control project.Water control project is with ship lock maintenance gate bearing working condition very severe, and it is long not only to carry span, and working load is big.Be used for so huge maintenance ship lock of scale, home or overseas does not all have mature theory and experience to use for reference.This maintenance vessel truck side bearing is selected the selfaligning roller bearing with conventional design in early days for use, bearing inner race does not have the oil groove oilhole, and the obliquely-angled design of two relative bearing axis of arc generatrix raceway of inner ring is unreasonable, therefore bearing in use, frictional force increases, greasy property is poor, occurs early failue and slight corrosion phenomenas such as burn, peeling easily.
Summary of the invention
Be the special Environmental Conditions of fitted bearing, overcome it and early failue forms such as burn, peeling and slight corrosion in use occur, the utility model proposes a kind of double-row self-aligning roller bearing, compare with the outer astragal oil groove oilhole of traditional mode of production, bearing inner race is provided with oil groove and oilhole, helps bearing and in use plays special lubrication.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of double-row self-aligning roller bearing, form by bearing outer ring 1, bearing inner race 4, solid cage 3 and roller 2, it is characterized in that, bearing inner race 4 is provided with oil groove 5 and oilhole 6, and two obliquely-angled a of the relative bearing axis of arc generatrix raceway of inner ring 4 are the 13-15 degree.Two obliquely-angled a of the relative bearing axis of arc generatrix raceway of described inner ring 4 are that 10 timesharing design of 14 degree and cooperation thereof are the most reasonable.
According to the applying working condition condition and the combination property characteristics of bearing, the design theory and the processing technology of this series bearing are innovated, and definite new structure.In the design of main parameter, utilize CAD and finite element analysis software to be optimized design, it is the most reasonable that lasso raceway size, roller diameter, length are equipped with; On structural design, according to hertz Elastic Contact theory, select the roller of science and the adaptation coefficient between the raceway for use, promptly inside and outside circle, rolling element radius of curvature reasonable disposition makes the contact stress that contacts bus between roller contact bus and lasso raceway even.But reach the bearing self-aligning, be not subject to the influence of bearing housing seat angular alignment error or bending shaft.The bearing decapacitation is born outside the radial load, can also bear the beidirectional axial load.
The beneficial effects of the utility model are: bearing in use, oilhole plays special lubrication, burn, peeling and corrosion phenomena do not occur.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1, bearing outer ring, 2, roller, 3, solid cage, 4, bearing inner race, 5, oil groove, 6, oilhole.
Embodiment
Lubricant oil on bearing inner race 4 oil groove 5 and oil groove oilhole 6, through retainer 3 internal diameters shuntings, enter the bearing element chamber, realize lubricated to bearing.The angle that two relative bearing axis of arc generatrix raceway of bearing inner race 4 are inclined to is 14 degree 10 minutes.Biserial rolling element 2 is between the inside and outside circle raceway, and the effect of retainer 3 is to isolate and the guide rolls rotation, makes shaft strength even.By inner ring, the assembly that roller and retainer are formed can be done rotation at any angle with respect to the outer ring, has just realized the function of self-aligning thus.
Claims (2)
1, a kind of double-row self-aligning roller bearing, form by bearing outer ring (1), bearing inner race (4), solid cage (3) and roller (2), it is characterized in that, bearing inner race (4) is provided with oil groove (5) and oilhole (6), and two obliquely-angled a of the relative bearing axis of arc generatrix raceway of inner ring (4) are the 13-15 degree.
2, a kind of double-row self-aligning roller bearing according to claim 1 is characterized in that, two obliquely-angled a of the relative bearing axis of arc generatrix raceway of described inner ring (4) are 14 degree 10 minutes.
