Description

A kind of end face seal bearing

Technical field

This utility model belongs to technical field of bearings and in particular to being a kind of end face seal bearing.

Background technology

Bearing is the supporting member in mechanical transmission mechanism, for determining rotary shaft and other part relative motion positions, it Quality directly affect the service behaviour of mechanical whole machine, drive the motion of associated mechanisms by the operating of bearing.Bearing is various Operate in environment, the adverse circumstances of particularly more windy and dusty operating mode, the gap between foreign body is easy to by the inside and outside circle of bearing is entered Enter raceway, make that bearing is on-stream to be damaged.

In order to solve the above problems, need to arrange sealing mechanism to prevent the omission of Bearing inner grease, it is to avoid bearing Under oil starvation state, operating uses, but sealing mechanism of the prior art all has poorly sealed, easy oil leak.Separately Outward, the sealing block in sealing mechanism easily falls off and sealing block is easily wound around accessory structure, causes sealing mechanism to damage.

Utility model content

The purpose of this utility model is to overcome defect mentioned above and deficiency, and provides a kind of end face seal bearing.

The technical scheme that this utility model realizes the employing of its purpose is as follows.

A kind of end face seal bearing, including inner ring, outer ring, rolling member, dust cap and block piece；Described inner ring and outer ring are in all Circular and concentric setting, and rolling member is located between inner ring and outer ring；Described block piece has two pieces, is divided into inner ring both sides And touch with inner ring phase；Described dust cap is fixed on outer ring, and dust cap extends internally, and dust cap the inner is embedded at block piece, and anti- Dirt lid is arranged with block piece gap；Described block piece includes cylinder gear and annulus gear；Described cylinder gear is cylindric in hollow；Described circle Ring gear is circular in hollow；Described annulus gear is integrally formed at cylinder gear side；The cylinder gear of one block piece and another gear The cylinder gear of part is threaded.

The outer wall of described annulus gear offers caulking groove；The inner bending of described dust cap is L-shaped；The inner of dust cap is embedded In caulking groove and with caulking groove interval setting.

This end face seal bearing, is embedded at the structure of block piece using dust cap the inner, improves bearing inner race, bearing outer ring Seal degree and dust cap between and intensity are it is ensured that mechanical transmission mechanism effectively runs for a long time.

Brief description

Fig. 1 is cross section structure diagram of the present utility model；

In figure：1- inner ring, 2- outer ring, 3- rolling member, 4- dust cap, 5- block piece, 5a- cylinder gear, 5b- annulus gear, 5c- are embedding Groove.

Specific embodiment

Below in conjunction with the accompanying drawings, this utility model is described in further detail.

A kind of end face seal bearing, including inner ring 1, outer ring 2, rolling member 3, dust cap 4 and block piece 5；Described inner ring 1 is with outward Circle 2 is all in circular and concentric setting, and rolling member 3 is located between inner ring 1 and outer ring 2；Described block piece 5 has two pieces, point Mutually touch located at inner ring 1 both sides and with inner ring 1；Described dust cap 4 is fixed on outer ring 2, and dust cap 4 extends internally, in dust cap 4 End is embedded at block piece 5, and dust cap 4 and the setting of block piece 5 gap；Described block piece 5 includes cylinder gear 5a and annulus gear 5b；Described circle It is in the cylindric of hollow that post keeps off 5a；It is in the circular of hollow that described annulus keeps off 5b；Described annulus gear 5b is integrally formed at cylinder gear 5a side；The cylinder of one block piece 5 keeps off 5a is threadeded with the cylinder gear 5a of another block piece 5.

The outer wall that described annulus keeps off 5b offers caulking groove 5c；The inner bending of described dust cap 4 is L-shaped；Dust cap 4 interior End be embedded at caulking groove 5c and with caulking groove 5c interval setting.

During installation, first the block piece 5 of side block piece 5 and opposite side is inserted in the mesopore of inner ring 1, the cylinder of a block piece 5 Gear 5a is threadeded with the cylinder gear 5a of another block piece 5, thus block piece 5 is fixed on inner ring 1.During work, block piece 5 is with inner ring 1 action.Two block pieces 5 are designed to threaded, are conducive to block piece 5 is installed on the inner ring 1 of different-thickness, increase product Versatility.Then dust cap 4 is positioned over the side of outer ring 2, and dust cap 4 the inner is embedded at caulking groove 5c, finally use screw Dust cap 4 is installed on outer ring 2.The inner L-shaped structure design of dust cap 4 is so that form labyrinth between dust cap 4 and block piece 5 Sealing structure, desirably prevents the seepage of lubricating oil and isolation sand and dust enter Bearing inner.

Therefore, this sealed bearings has good sealing property, dust cap 4 to inner ring 1 and outer ring 2 no frictionally damage, be easy to pacify Assembly and disassembly are unloaded.

This utility model is illustrated according to embodiment, and on the premise of without departing from present principles, this device can also be made Go out some deformation and improve.It should be pointed out that the technical scheme that the mode such as all employing equivalents or equivalent transformation is obtained, all fall In protection domain of the present utility model.
