Abstract

The utility model provides a shaft end sealing structure for a bearing box body. The shaft end sealing structure consists of an end cover (1), a pressing cover (2), a rubber cushion (4) and an oil baffle (6), and is characterized in that the rubber cushion (4) is cushioned between adhesion faces of the pressing cover (2) and the end cover (1), and is fixedly connected with the adhesion faces by bolts; the oil baffle (6) is located on the inner side of the end cover (1) and is sleeved on a shaft (3); and the end cover (1) is connected with a box body (5) through bolts. The shaft end sealing structure provided by the utility model has the advantages of simple structure and low manufacturing cost.

Description

A kind of bearing housing sealing structure of shaft end

Technical field

The utility model relates to a kind of bearing housing sealing structure of shaft end, does not relate to a kind of sealing structure of shaft end that is used on the machinery such as speed reducer, bearing support.

Background technique

The sealing means of axle head has used various seal rings mostly in the machinery (like speed reducer, bearing support etc.) at present, because beam warp often rotates; So the endoporus of seal ring often is worn soon; Thereby make sealing effect undesirable, oil leakage phenomenon often takes place, and seal ring is changed very frequent; Make the operating cost of equipment very high, and the time that maintenance of equipment is wasted has been caused great influence to production.

The model utility content

The purpose of the utility model is to provide a kind of simple in structure, good sealing effect, does not have the bearing housing sealing structure of shaft end of easily damaged parts.

The utility model solves the technological scheme that its technical problem adopted:

A kind of bearing housing sealing structure of shaft end of the utility model; Form by end cap, gland, rubber pad and oil deflector; It is characterized in that: be lined with rubber pad between the faying surface of gland and end cap; Connect with bolt, it is inboard and be enclosed within on the axle that oil deflector is in end cap, is connected with bolt between end cap and the casing.

The shape facility of said end cap is: lean on the inboard of end cap that convex portion is arranged, lug boss is divided into toroidal, and the external cylindrical surface of annulus has a circular groove; Two to four little circular grooves are arranged on the inner cylindrical surface of annulus, a groove is arranged under the annulus inner cylindrical surface, lean on the outside of end cap that one counter sink is arranged; Counter sink be shaped as the cylindrical hole shape; Its diameter has under the counter sink with the inboard of end cap to communicate greater than the diameter of the external cylindrical surface of annulus, and downward-sloping hole.

Said oil deflector adopts rubber seal, make its endoporus with spool between become interference fit.

The beneficial effect of the utility model is that a kind of bearing housing sealing structure of shaft end of the utility model has simple in structure; Fabricating cost is low; No easily damaged parts does not produce any maintenance expenses basically, is that the structure that the present various seal ring modes of employing seal can't be compared.

Description of drawings

This specification comprises following two width of cloth accompanying drawings:

Fig. 1 is the work schematic representation of a kind of bearing housing sealing structure of shaft end of the utility model.

Fig. 2 is the structural representation of the parts end cap of a kind of bearing housing sealing structure of shaft end of the utility model.

Component, toponym and pairing mark among the figure: end cap 1, gland 2, axle 3, rubber pad 4, casing 5, oil deflector 6, circular groove 11, groove 12, roundlet arc groove 13, hole 14, counter sink 15.

Embodiment

Below in conjunction with accompanying drawing the utility model is further specified.

With reference to Fig. 1; A kind of bearing housing sealing structure of shaft end of the utility model; Form by end cap 1, gland 2, rubber pad 4 and oil deflector 6, it is characterized in that: be lined with rubber pad 4 between the faying surface of gland 2 and end cap 1, connect with bolt; It is inboard and be enclosed within on the axle 3 that oil deflector 6 is in end cap 1, is connected with bolt between end cap 1 and the casing 5.

With reference to Fig. 2, the shape facility of said end cap 1 is: lean on the inboard of end cap 1 that convex portion is arranged, lug boss is divided into toroidal; The external cylindrical surface of annulus has a circular groove 11; Two to four roundlet arc grooves 13 are arranged on the inner cylindrical surface of annulus, a groove 12 is arranged under the annulus inner cylindrical surface, lean on the outside of end cap 1 that a counter sink 15 is arranged; Counter sink 15 be shaped as the cylindrical hole shape; Its diameter has under the counter sink 15 with the inboard of end cap 1 to communicate greater than the diameter of the external cylindrical surface of annulus, and downward-sloping hole 14.

With reference to Fig. 1, said oil deflector 6 adopts is a kind of in the rubber seal, make its endoporus with spool between become interference fit.

Some principles of the above a kind of bearing housing sealing structure of shaft end of the utility model that just explains through diagrams; Be not be to a kind of bearing housing sealing structure of shaft end of the utility model be confined to shown in described concrete structure and Applicable scope in; So every the modify and equivalent that might be utilized all belongs to the claim that the utility model is applied for.
