Description

A kind of taper roll bearing

Technical field

This practicality is related to a kind of technical field of bearings, more specifically to a kind of taper roll bearing.

Background technology

Taper roll bearing is designed as, and inner ring, the roller surface of outer ring and roller cone vertex are gathered on bearing centre axis A bit, radial load acts on bearing, then generates axial force.It therefore, must be using 2 bearings towards using or as double in pairs Shaft coupling is held, and double-row bearing uses.Combination and double-row conical bearing, it is interior when Radial Loads are in taper roll bearing Portion's contact angle can generate induced axial load.The generation of induced axial load makes the separated active force of inner ring, outer ring, so usually adopting With paired or multiple row taper roll bearing to offset this power.And the single seal groove of existing taper roll bearing, easily make Dust class enters in bearing, and bearing life is caused to shorten.

Utility model content

The purpose of the present invention provides a kind of steel and sealing ring that rubber phase combines aiming at the deficiency of the prior art Taper roll bearing.

A kind of taper roll bearing, including outer ring, inner ring, roller and retainer, the quantity of the inner ring is 2, roller Also it is 2 circles, the self-locking ring of hook-type is equipped between two inner rings, the both ends of bearing is equipped with sealing ring；The sealing ring is by One catch, labyrinth ring and the second catch composition, first catch and the second catch are half opposite frame folded structure, second Catch wherein one end is equipped with oblique section, to be embedded labyrinth ring, is sealed cavity.

As further improving and supplementing to said program, this practicality further includes following additional technical feature：

The both ends of the outer ring are equipped with guide section, easy for installation.

First catch and the material of the second catch are 08F, plasticity and good toughness.

The material of labyrinth ring is NBR, and service life is long.

It can reach following advantageous effect using the utility model：It is changed significantly by increasing guard circle in Bearing outer The good sealing performance of bearing, effectively prevents external water and sundries from entering Bearing inner, substantially increases the service life of bearing, And by setting self-locking ring, it can not only bear outside very big radial and axial load, tilting moment can also be born, further Extend the service life of bearing.

Description of the drawings

Fig. 1 is the structure diagram of the utility model.

Specific embodiment

Specific embodiment of the present utility model is described in detail below in conjunction with the accompanying drawings.

As shown in Figure 1, the utility model is a kind of taper roll bearing.

Taper roll bearing described in the present embodiment, including outer ring 1, inner ring 2, roller 3 and retainer 4, the inner ring 2 Quantity for 2, roller 3 is also 2 circles, and the self-locking ring 6 of hook-type is equipped between two inner rings 2, locks and removes conveniently, not only may be used To bear outside very big radial and axial load, tilting moment can also be born.The both ends of bearing are equipped with sealing ring 5；Described Sealing ring 5 is made of the first catch 51,52 and second catch 53 of labyrinth ring, and first catch 51 and the second catch 53 are phase To half frame folded structure, on the second catch 53 wherein one end be equipped with oblique section, to be embedded labyrinth ring 52, be sealed sky Chamber, good airproof performance prevent sundries etc. to enter in bearing, extend the service life of bearing.

Further, the both ends of the outer ring 1 are equipped with, outer diameter is slightly less than the guide section 11 of intermediate outer ring outer diameter, installation It is convenient during bearing.

Further, the material of first catch 51 and the second catch 53 is 08F, plasticity and good toughness, is used Long lifespan.

Further, the material of the labyrinth ring 52 is NBR, and NBR is nitrile rubber, and resistance to temperature range is big, is used Long lifespan.

The present embodiment pertains only to the improvement of planform, is not related to the improvement of assembly method.

It is the preferred embodiment of the utility model above, the scope of protection of the utility model is not limited, for ability The deformation and improvement that field technique personnel mentality of designing according to the present utility model is made, should all be considered as the protection of the utility model Within the scope of.
