In addition, the inner sealing ring is provided with an annular bulge, and the annular bulge is positioned at the movable gap. The annular bulge can ensure that the inner sealing ring and the sealed bearing have a certain gap, and can reduce the contact area of the inner sealing ring and the sealed bearing.
Drawings
The invention will be further explained with reference to the following figures and examples:
FIG. 1 is a three-dimensional structure diagram of the present invention;
fig. 2 is a three-dimensional view of the carrier roller body of the utility model;
FIG. 3 is a view of the installation position of the sealed bearing of the present invention;
fig. 4 is an axial expansion view of the outer sealing ring, the inner sealing ring and the elastic snap ring of the present invention;
fig. 5 is a three-dimensional view of the outer sealing ring of the present invention.
In the figure: the roller carrier comprises a carrier roller body 1, a rotating shaft mounting channel 101, a rotating shaft 2, a sealing assembly mounting groove 3, an outer sealing ring 4, an inner sealing ring 5, an annular protrusion 501, a sealing type bearing 6 and an elastic snap ring 7.
Detailed Description
The preferable scheme is as shown in fig. 1 to 5, the high-sealing carrier roller for the mine belt conveyor conveying equipment comprises a carrier roller body 1, a rotating shaft installation channel 101 is arranged at the axis of the carrier roller body 1, a rotating shaft 2 is installed in the rotating shaft installation channel 101, sealing assembly installation grooves 3 are formed in two ends of the rotating shaft installation channel 101, a bearing is arranged in each sealing assembly installation groove 3, an outer sealing ring 4 and an inner sealing ring 5 are arranged outside the bearing, the outer sealing ring 4 is in sliding fit with the inner sealing ring 5, and the outer sealing ring 4 and the inner sealing ring 5 are used for sealing the bearing.
The general carrier roller only comprises a carrier roller body 1, a rotating shaft 2 and a bearing, the sealing performance and the water resistance are different, more dust is generated around the conveying equipment of the mine belt conveyor, the operation environment is poor, the carrier roller is easily jammed due to the fact that the dust covers the bearing, the rotating resistance is increased, and therefore the working load of the belt conveyor is increased. This technical scheme improves its structure on current bearing roller basis, specifically is: a sealing component mounting groove 3 is additionally arranged, an outer sealing ring 4 and an inner sealing ring 5 are arranged in the sealing component mounting groove 3, and the outer sealing ring 4 and the inner sealing ring 5 are used for shielding the bearing, so that the dust shielding effect is achieved; rainwater can be prevented from entering the rotating shaft mounting channel 101 to cause the rotating shaft 2 to be corroded.
Further, the bearing is a sealed bearing 6 with a seal ring. In a general bearing, a sealing cover is not added, the ball is exposed, and the surface of the ball is easily covered with dust. And the common bearing is replaced by the sealing type bearing 6 with the sealing ring, so that the dustproof performance of the carrier roller can be improved. The generally sealed bearing 6 is commonly used in a submersible pump and is not applied to a belt conveyor at present.
Further, inner seal ring 5 is the nylon seal ring, and outer seal ring 4 is the metal material, and inner seal ring 5 is used for cup jointing in pivot 2, and inner seal ring 5 and 4 sliding fit of outer seal ring, the laminating of 4 outer walls of outer seal ring and 3 inner walls of seal assembly mounting groove. Preferably, the inner wall of the outer sealing ring 4 is of a concave structure, the outer wall of the inner sealing ring 5 is of a convex structure, and lubricating oil is arranged between the inner sealing ring 5 and the outer sealing ring 4. The side surface of the outer sealing ring 4 is provided with an annular groove, so that on one hand, the material is saved, and on the other hand, the outer sealing ring 4 has certain elasticity.
Further, movable gaps are arranged between the outer sealing ring 4, the inner sealing ring 5 and the sealed bearing 6. The running clearance serves to reduce the friction of the sealed bearing 6 with the outer sealing ring 4 and the inner sealing ring 5.
Further, the inner seal ring 5 is provided with an annular protrusion 501, and the annular protrusion 501 is located at the movable gap. The annular protrusion 501 can ensure that the inner seal ring 5 and the sealed bearing 6 have a certain gap, and can also reduce the contact area between the inner seal ring 5 and the sealed bearing 6.
Furthermore, the outer part of the inner sealing ring 5 is provided with an elastic clamping ring 7, and the elastic clamping ring 7 is sleeved on the rotating shaft 2. The elastic snap ring 7 plays a role in limiting and avoids the axial movement of the inner sealing ring 5.
