Abstract
The utility model discloses a contact-type sealing nylon carrier roller; a bearing is symmetrically assembled on a stair on both ends of a radial central line of a stair shaft; an inner maze sealing ring assembled in an annular sealing ring of a bearing seat close to the bearing is in an interference fit with the stair shaft; the bearing seat is fixed in the shaft body from both ends of the stair shaft in the manner of interference fit; a V-shaped sealing piece is arranged on a V-shaped sealing piece positioning step on the inner side of the outer end of the bearing seat in the manner of interference fit; and a limit ring close to the V-shaped sealing piece is arranged in an annular clamping groove on the inner side of the inner hole on the outer end of the bearing seat. The contact-type sealing nylon carrier roller can resist water and dust, thereby reducing the rotation resistance of the carrier roller and prolonging 3-5 times of the service life of the carrier roller; and the contact-type sealing nylon carrier roller has practical and expanding values.
Description
Technical field
The utility model relates to a kind of carrying roller, relates in particular to a kind of contact-type seal nylon carrying roller for using on the band conveyor of carrying bulk material.
Background technology
Before the utility model, in different poses and with different expressions for its structure of carrying roller and the shape used on the band conveyor of carrying the material that looses to use, and bring into play separately effect; But problem is: most of carrying roller is made of metallic material, there is the sealing property defective, the sealing arrangement of prior art middle idler roller is generally non-contacting seal spare, and non-contacting seal spare itself does not have sealing property, can only rely on to add grease in the space of non-contacting seal spare and reach the leak free purpose; But grease also can be along with non-contacting seal spare produces motion in rotary course to carry carrying roller, grease can produce in motion process and shear frictional heat, cause the grease temperature build-up, grease can cause that when temperature is too high oil, fat in the grease separates, thereby make grease lose lubricated and sealing function fully, aggravated the bearing influence in service life, and then shortened the service life of carrying roller; On the other hand, carrying roller in use, because of the sealing effectiveness of non-contacting seal spare bad, and make carrying roller sealing arrangement water inlet, advance ash, increase the bearing resistance of carrying roller, even can stuck bearing, cause carrying roller not rotate, belt scratch phenomenon appears.
Summary of the invention
Task to be solved in the utility model provides a kind of good seal performance, energy waterproof and dustproof, reduces the carrying roller resistance and improves the carrying roller contact-type seal nylon carrying roller in service life.
For finishing above-mentioned task, the technical solution adopted in the utility model is: described a kind of contact-type seal nylon carrying roller comprises that roll body, bearing seat, interior labyrinth seal, V-seal spare, stop bit circle, bearing and ladder advance axle, the bearing symmetry is assemblied in ladder and enters the step place of the diameter of axle to the line of centers two ends, the interior labyrinth seal that is loaded in the bearing seat annular seal groove near bearing advances axle one-tenth interference fit with ladder, bearing seat advances axle from ladder two ends are fixed in the roll body with the form of interference fit, allow position of bearings on the bearing positioning step of bearing seat inboard.V-seal spare is assemblied on the V-seal spare positioning step of inboard, bearing seat outer end with the form of interference fit, has the stop bit circle to be assemblied in the annular arrangement draw-in groove of endoporus inboard, bearing seat outer end near V-seal spare.
Adopt a kind of contact-type seal nylon carrying roller that as above technical scheme provides compared with prior art, technique effect is:
1. because the roll body of this contact-type seal nylon carrying roller and sealing member use non-metallic material to make non-corrosive;
The V-seal spare that 2. annular seal lip small size contact is arranged can prevent effectively that exterior water, dust and gas from entering the carrying roller sealing arrangement, can reduce roller revolving resistance again;
3. can prolong 3～5 times of carrying roller service lifes.
Description of drawings
Fig. 1 is the partial schematic sectional view of a kind of contact-type seal nylon carrying roller described in the utility model, also is Figure of abstract of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail.
A kind of contact-type seal nylon carrying roller as shown in Figure 1 comprises that roll body 1, bearing seat 2, interior labyrinth seal 3, V-seal spare 4, stop bit circle 5, bearing 6 and ladder advance axle 7, wherein roll body 1 can select for use the MC nylon material to make, bearing seat 2, interior labyrinth seal 3 and stop bit circle 5 can select for use the inelastic body High molecular material to make, V-seal spare 4 can select for use elastomer macromolecule material to make, and ladder advances axle 7 and can select for use metallic material to make, bearing 6 can be selected ball bearing of main shaft for use, product, prior art can be bought in market.
