Abstract
The utility model relates to an oil seal, which is composed of an oil seal body 1 and an oil baffle ring 2 which are connected together, and the outer periphery of the oil baffle ring 2 is provided with an annular slot 3. When a rotating shaft 4 runs, the lubricating oil splashed from bearing rolling balls 5 to the conical surface of a bearing end cover 6 can flow to the utility model, with rotating flow in the annular slot 3 on the oil baffle ring 2, and then the lubricating oil can flow back to an oil tank from an oil return bore 7 finally. The structure avoids the phenomenon of the lubricating oil flowing to the inner wall of the oil seal, so the service life of the oil seal is extended, and the oil leakage problem is solved. The utility model has the advantages of simple structure and convenient manufacture.
Description
The utility model relates to the dynamic sealing technology of rotating machinery.
At present, the oil sealing that is used for machinery input, the anti-leakage of oil in output shaft place, its excircle can guarantee good sealability, but its inwall because and closely cooperating and the corrosion of lubricant oil between the rotating shaft, cause oil sealing unavoidably to have wearing and tearing, aging, thereby cause leakage of oil, must change oil sealing.Like this, not only cause spillage of material many, and the service work intensity that causes thus is big, long in time limit, certainly will influence production.
The purpose of this utility model is to provide a kind of good leak-proof effect, long oil sealing of life-span.
The utility model is to reach the oil deflector (2) that fuses with it by oil sealing main body (1) to constitute, and circular groove (3) is arranged on the excircle of oil deflector (2).
Advantage of the present utility model is: the sealability that 1, has strengthened the running shaft place; 2, improve the working life of oil sealing, reduced the replacing frequency of oil sealing; 3, save material, the cost of overhaul, improved manufacturing efficiency.
Fig. 1 is the utility model structural drawing;
Fig. 2 is the erection drawing of the utility model and rotor axis mechanical.
Details are as follows to the utility model structure and working principle below in conjunction with drawings and Examples:
As shown in Figure 1, oil deflector (2) links into an integrated entity with oil sealing main body (1), and on the excircle of oil deflector (2), be processed with circular groove (3), the internal diameter of oil deflector (2) can be greater than the internal diameter of oil sealing main body (1), make between itself and rotating shaft (4) to have certain interval, its external diameter is less than the external diameter of oil sealing main body (1).As shown in Figure 2, when rotating shaft (4) is rotated, from the lubricant oil that flows out between bearing ball (5), under action of centrifugal force, be splashed on the conical surface of bearing (ball) cover (6), flow to the excircle of oil deflector (2) then, the bottom along circular groove (3) circulation to bearing (ball) cover (6) flows into oil sump through spill port (7).This oil sealing also can with the supporting use of oil thrower ring (8), when small part oil when circular groove (3) flows to the inner conical surface of oil thrower ring (8) because the rotation of oil thrower ring (8) can be got rid of oil on the conical surface of bearing (ball) cover (6) again, repeat said process then.
Claims (4)
1, a kind of oil sealing is characterized in that this oil sealing is made of oil sealing main body (1) and oil deflector (2), has circular groove (3) outside the oil deflector (2).
2, oil sealing according to claim 1, the internal diameter that it is characterized in that oil deflector (2) be greater than oil sealing main body (1) internal diameter, thereby and certain interval arranged between rotating shaft.
3, oil sealing according to claim 1 and 2, the external diameter that it is characterized in that oil deflector (2) is less than oil sealing main body (1) external diameter.
4, oil sealing according to claim 1 and 2 is characterized in that this oil sealing and oil thrower ring (8) are used.
