Description

Anti-corrosion hard alloy reinforced waterproof carrier roller

Technical Field

The utility model belongs to the technical field of the bearing roller, especially, relate to a waterproof bearing roller of anticorrosive carbide reinforcing.

Background

The normal work of whole conveying link can direct influence in any bearing roller trouble appears in the belt feeder, and in a lot of service environments, the bearing roller works under adverse circumstances for a long time, and current bearing roller leakproofness is poor, easily leads to water and dirt to corrode inside the bearing frame subassembly along the spindle nose to the bearing roller rubs with the conveyor belt for a long time, makes the barrel wall thickness loss gradually even wear through, therefore needs to improve.

Disclosure of Invention

The utility model aims at providing a waterproof bearing roller of anticorrosive carbide reinforcing to the not enough of above-mentioned prior art existence, it has simple structure, and multiple sealed effectual, long service life's characteristics.

In order to realize the purpose, the utility model discloses the technical scheme who adopts is: the utility model provides a waterproof bearing roller of anticorrosive carbide reinforcing, includes the bearing roller body, the both ends of bearing roller body are equipped with the holding tank, be equipped with the bearing frame in the holding tank and install the bearing roller axle in the bearing frame, still be equipped with watertight fittings in the holding tank, the last shaft hole that is equipped with of watertight fittings, the inner wall in shaft hole is seted up and is equipped with first recess, be equipped with first ring packing in the first recess, one side that watertight fittings is close to the bearing frame is equipped with the second recess, be equipped with second ring packing in the second recess, second ring packing and bearing frame butt, first ring packing and bearing roller axle interference fit.

Further, the cross section of the first annular sealing ring is trapezoid with arc edges.

Further, the cross section of the second annular sealing ring is L-shaped.

Further, the holding tank includes outer holding tank and the interior groove of holding in proper order from outside to inside, the diameter that holds the groove outward is greater than the diameter that holds the groove in the interior.

Further, the outer diameter of the waterproof device is equal to the diameter of the outer containing groove, and the outer diameter of the bearing seat is equal to the diameter of the inner containing groove.

Furthermore, the outer wall of the carrier roller body is provided with a metal annular bulge

After the structure is adopted, compared with the prior art, the utility model the advantage that has is:

1. the utility model discloses be equipped with can reduce the connection gap between watertight fittings and the bearing roller axle with bearing roller shaft interference fit's first ring type seal circle, avoid inside water etc. along the bearing roller axle corrodes bearing frame subassembly, increase of service life.

2. The utility model discloses be equipped with the second ring seal of L shape, can reduce the connection gap between watertight fittings and the bearing roller body like this, avoid inside water etc. enters into the erosion bearing frame subassembly along the cell wall of holding tank, increase of service life.

3. The utility model discloses be provided with the cyclic annular arch of metal at the outer wall of bearing roller body, can reduce area of contact between bearing roller body and the conveyor belt and then slow down wearing and tearing, increase of service life like this.

Detailed Description

The following description is only for the preferred embodiment of the present invention, and the protection scope of the present invention is not limited thereby, the present invention will be further explained with reference to the drawings and the embodiments.

Examples, see fig. 1-2: the utility model provides a waterproof bearing roller of anticorrosive carbide reinforcing, includes bearing roller body 10, is equipped with the holding tank at the both ends of bearing roller body 10, is equipped with bearing frame 30 and installs the bearing roller axle 20 in bearing frame 30 in the holding tank, its characterized in that: still be equipped with watertight fittings 40 in the holding tank, wherein watertight fittings 40 are equipped with the shaft hole, set up at the inner wall in shaft hole and be equipped with first recess 41, be equipped with first ring type seal 61 in first recess 41, first ring type seal 61 and bearing roller axle 20 interference fit when using, can be better for bearing roller axle 20 through first ring type seal 61, its cross section of first ring type seal 61 of adoption is trapezoidal and the diameter that first ring type seal 61 is close to bearing frame 30 one end for taking the arc limit is greater than its diameter of keeping away from bearing frame 30 one end.

Further, a second groove 42 is formed in one side, close to the bearing seat 30, of the waterproof device 40, a second annular sealing ring 62 is arranged in the second groove 42, one side, far away from the second groove 42, of the second annular sealing ring 62 is provided with a groove wall abutting against the accommodating groove, the second annular sealing ring 62 abuts against the bearing seat 30, and the cross section of the specific second annular sealing ring 62 is in an L shape, so that the sealing effect can be just achieved.

Further, the housing groove includes an outer housing groove 11 and an inner housing groove 12 in sequence from outside to inside, wherein the diameter of the outer housing groove 11 is larger than the diameter of the inner housing groove 12, wherein the outer diameter of the waterproof device 40 is equal to the diameter of the outer housing groove 11, wherein the outer diameter of the bearing housing 30 is equal to the diameter of the inner housing groove 12, and wherein the height of the bearing housing 30 is equal to the height of the inner housing groove 12, so that when the bearing housing 30 is placed in the inner housing groove 12 and the waterproof device 40 is placed in the outer housing groove 11, the second annular seal ring 62 can abut against the bearing housing 30 to perform a sealing function.

Further, the outer wall of the carrier roller body 10 is provided with the metal annular protrusion 50, wherein the metal annular protrusion 50 is connected with the carrier roller body 10 through welding to improve stability, so that the contact area between the carrier roller body 10 and a conveying belt can be reduced, the abrasion is reduced, and the service life is prolonged.

The above-mentioned embodiment is only the preferred embodiment of the present invention, and does not limit the protection scope of the present invention according to this, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
