Abstract
The utility model discloses a bearing with an outer seal. The bearing comprises an outer ring with a flange, an inner ring and a rolling body, wherein the rolling body is arranged between the inner ring and the outer ring; a retainer is arranged outside the rolling body; sealing bodies are also arranged on two sides of the rolling body between the inner ring and the outer ring; channels for fixing the sealing bodies are arranged on the outer ring; sealing grooves are concavely formed in the position, corresponding to the channels, on the outer side of the outer ring; a plurality of connecting ducts are arranged between the sealing grooves and the channels; the connecting ducts are evenly distributed in a radiation manner by taking the axis of the outer ring as a center; connection bumps which are equal to the connecting ducts in quantity are arranged on the outer sides of the sealing bodies; the sealing bodies are clamped into the channels; the connection bumps are clamped into the connecting ducts; sealing rings are injection-molded into the connecting ducts and the sealing grooves; the sealing rings are fixedly connected with the connection bumps of the sealing bodies. The bearing has the beneficial effects that the sealing rings which are integrally injection-molded together with the sealing bodies are unlikely to fall off from the outer ring due to existence of the connecting ducts.
Description
Technical field
The utility model relates to the improvement of a kind of bearing, particularly bearing seal.
Background technique
Existing bearing exterior edge face is not generally provided with sealing, establishes Packed words, and bearing was put into to be installed when upper, and sealing also easily departs from from outer ring, more unreliable, can fall into and in gear assembly, damage whole machinery when serious.
Summary of the invention
The deficiency easily departing from from outer ring in order to overcome the seal ring of existing bearing external sealed, the bearing that the utility model provides a kind of external sealed to be not easy to depart from from outer ring.
The technical scheme in the invention for solving the technical problem is: a kind of bearing with external sealed, comprise that one with the outer ring of rib, inner ring, rolling element between inner ring and outer ring, described rolling element is provided with retainer outward, between described inner ring and outer ring, rolling element both sides are also provided with seal, described outer ring is provided with the raceway groove of fixing seal body, outside described outer ring, corresponding raceway groove position is also concaved with sealed groove, between described sealed groove and raceway groove, be provided with some connection, beyond described connection road, centered by coil axis, homogeneous radiation distributes, described seal outside is provided with the connection projection equal with being connected number, described seal snaps in raceway groove and in described connection projection Snap joint road, described connection road with in sealed groove, be injected with sealing ring and being fixed together with the projection that is connected of seal.
The local stiffened strengthening of seal, is also provided with skeleton in described seal.
A good selection, described connection road be connected projection and be provided with 16.
The utility model is used with the bearing of prior art in use, and the sealing ring on outer ring withstands outer ring surface and plays seal action.
The beneficial effects of the utility model are: due to the existence in some connections road, integrated sealing ring together with being injection-moulded in seal is not easy to come off from outer ring.
