Abstract
The utility model discloses a double-cutting-edge framework oil seal for a backing bearing. The double-cutting-edge framework oil seal can bear pressure over 3 kilograms and meet a requirement on a rotating speed of 10 meters per second, is abrasion-proof and durable, can be used for avoiding oil leakage of the bearing, is convenient to assemble and disassemble, and can be used for prolonging the service life of the backing bearing, and reducing the production cost of the backing bearing. The double-cutting-edge framework oil seal consists of an outer ring flange, a nitrile rubber outer oil seal, a steel framework and an outer check ring, wherein the outer check ring is internally and coaxially provided with the outer ring flange; the nitrile rubber outer oil seal is arranged between the outer ring flange and the outer check ring; the L-shaped steel framework is arranged in the middle of the nitrile rubber outer oil seal; and two cutting edges of which the side sections form a fork shape are arranged at the upper end of the nitrile rubber outer oil seal. The double-cutting-edge framework oil seal has a simple structure, is convenient to use and mount, and can be used for reducing the abrasion; a good sealing effect is achieved; and requirements of the oil seal of the backing bearing on high pressure resistance and high rotating speed are met; and furthermore, the processing and manufacturing cost is low, so that the investment is low, and the double-cutting-edge framework oil seal is convenient to popularize.
Description
Technical field
The utility model relates to oil sealing, especially a kind of twolip limit outside framework oil seal of back lining bearing.
Background technique
At present, the outside framework oil seal of existing back lining bearing generally all is that spring is arranged, Steel Skeleton, and the nitrile rubber oil sealing is formed, and this structure is complicated, and processing cost is higher.For back lining bearing, require oil sealing can bear the pressure more than 3 kilograms, and can satisfy the rotating speed requirement of 10m/s, common reinforced seal is difficult to the sealing effect that reaches such.Domestic certain tame back lining bearing manufacturing enterprise has adopted the Che Shi combination seal, though this oil sealing also can play seal action, working life is shorter, and the installation and removal process is complicated.
In view of the foregoing, the outside framework oil seal of existing back lining bearing needs to improve.
The model utility content
The purpose of the utility model is in order to overcome deficiency of the prior art, a kind of twolip limit outside framework oil seal of back lining bearing to be provided, can bear the pressure more than 3 kilograms, satisfying the rotating speed requirement of 10m/s, and is wear-resisting, durable, avoided the bearing leakage of oil; Easy for installation, dismounting has easily prolonged working life simultaneously, has reduced cost of production.
The utility model adopts following technological scheme to achieve these goals: a kind of twolip limit outside framework oil seal of back lining bearing is by the outer ring rib, the nitrile rubber outer oil seal, and Steel Skeleton, outer back-up ring constitutes; Coaxial in the rib of outer ring outer back-up ring is set, between outer ring rib and the outer back-up ring nitrile rubber outer oil seal is set, nitrile rubber outer oil seal middle part is provided with L shaped Steel Skeleton.
The upper end of described nitrile rubber outer oil seal is provided with the twolip limit that the side section is a fork-shaped.
The beneficial effect of the utility model is: simple in structure, easy to install and use, reduce wearing and tearing; The oil sealing that has satisfied back lining bearing bears big pressure, high-revolving requirement.Invest lowly, be convenient to promote.
The oil seal structure of the utility model is simpler, mainly contains Steel Skeleton and nitrile rubber outer oil seal and forms.Bearing is when work, and the two twolip limits on top contact with the outer ring rib of rotation, and the bottom of band Steel Skeleton is fixed on the static outer back-up ring.Because outer ring rib and twolip limit constantly rub, be easy to cause the wearing and tearing of sword limit, do not have seal action.Through the proportioning of nitrile rubber material being improved and to the appropriate design of twolip limit and outer rib angle, the degree of sword limit wearing and tearing is less greatly, through the installation use, can play good sealing effect.And processing and low cost of manufacture, the back lining bearing oil sealing of our company has all adopted this structure at present.
