Abstract
The utility model relates to a lubrication sealing structure of a novel high-speed low resistance roller. The two ends of the roller are provided with bearing seats. The end of the bearing seat is provided with a lubricating oil cavity. The utility model is characterized in that an inner baffle plate, a bearing, a labyrinth seal, a distance ring, a sealing ring and an outer cover are arranged in the lubricating oil cavity from inside to outside, the bearing adopts thin oil lubrication, and the distance ring, the sealing ring and the outer cover adopt lubricating grease lubrication. The utility model reduces the rotating resistance of the roller. The end part of the roller is waterproof and dustproof. The service life of the bearing is prolonged.
Description
Technical field
The utility model relates to the belt transporter technical field, further relates to the carrying roller on the belt transporter, the concrete lubrication sealing structure that relates to the carrying roller end.
Background technology
One of critical component of roller-type belt conveyer, because its consumption in equipment is big, the quality of its performance and quality directly influences power consumption, traveling comfort and the reliability of whole piece conveyer, also the follow-up maintenance cost of remote effect complete machine.And the performance of carrying roller and quality depend on the service life of Idler bearing, and depend on sealing and lubricated the service life of bearing.
Under coal mine, pollutants mainly is trickle and coal slime, and in steel plant, cement mill and power plant, pollutants mainly is a dust.As everyone knows, after water or dust enter bearing, all the grease in the bearing " can be eaten up ", bearing can not get lubricating, and the life-span promptly reduces hundred times, will soon lose efficacy, and perhaps stuck by dust, carrying roller is also scrapped immediately; So not only delay production but also increased maintenance cost.
The utility model content
Technical problem to be solved in the utility model is, overcome the problem that existing carrying roller exists, the carrying roller lubrication sealing structure of a kind of high life is provided, this structure can improve carrying roller service life, reduce the rotational resistance of carrying roller, guarantee the reliable pulsation-free operation of belt conveyer.
In order to address the above problem the technical solution of the utility model is such:
The lubrication sealing structure of novel high speed low-resistance carrying roller, two ends at carrying roller are provided with bearing seat, the bearing seat end has a lubricant reservoir, it is characterized in that, be provided with Internal baffle, bearing, labyrinth packing, spacer ring, seal ring, enclosing cover with this from inside to outside in the lubricant reservoir, bearing adopts thin oil lubricant, and spacer ring, seal ring, enclosing cover adopt grease lubrication.
Described seal ring is a serpentine, and spacer ring, seal ring, enclosing cover form the labyrinth packing that has two cavitys, and grease is filled in the cavity.
Described labyrinth packing is made of inner seal liner and outside seal may, and the interlaced formation labyrinth packing of inner seal liner and outside seal may also is provided with O type circle in the labyrinth packing outside.
Beneficial effect, lubrication sealing structure described in the utility model has reduced the rotational resistance of carrying roller, and carrying roller end waterproof and dustproof has prolonged service life of bearing greatly.
Description of drawings
Describe the utility model in detail below in conjunction with the drawings and specific embodiments;
Fig. 1 is the structural representation of the lubrication sealing structure of the utility model novel high speed low-resistance carrying roller.
Wherein 1, back-up ring 2, enclosing cover 3, seal ring 4, spacer ring 5, inner seal liner 6, outside seal may 7, bearing 8, Internal baffle 9, roller carrier shaft 10, bearing seat 11, housing 12, O type circle
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
Referring to Fig. 1
Lubrication sealing structure comprises roller carrier shaft 9, bearing seat 10, housing 11, inner seal liner 5, outside seal may 6, and bearing seat 10 is single-piece spaces, the interlaced formation labyrinth packing of inner seal liner and outside seal may.By inner seal liner 5, outside seal may 6, bearing 7, O type circle 12 inner space of bearing seat 10 is formed a lubricant reservoir, lubricating oil is lived oilhole by axle head new lubricating oil is injected lubricant reservoir, and the old lubricating oil in the carrying roller flows out by other end oilhole.The inboard of bearing 7 also is provided with an Internal baffle 8, makes bearing and bearing seat 10 separate.
The swivel of bearing seat 10 and housing 11 integrally welded formation carrying rollers; Form another labyrinth packing in the sealing member outside by enclosing cover 2, seal ring 3, spacer ring 4, form 2 cavity A, C therebetween.Different lubricated and sealing means is adopted in the outside in the bearing, and its inboard is a fully enclosed oil pocket, adopts thin oil lubricant in the oil pocket; And labyrinth packing, the sealing of O type circle, grease seal are adopted in the outside, promptly pour the purpose that grease reaches waterproof and dustproof in cavity A, C.Further in order to form labyrinth packing, seal ring 3 is a serpentine, and spacer ring 4, seal ring 3, enclosing cover 2 form the labyrinth packing that has two cavitys.Also be provided with a back-up ring 1 in the outside of enclosing cover 2, prevent that enclosing cover 2 from coming off.
The characteristics of this structure are:
1, bearing lubrication is lubricated by thin oil, like this than the rotational resistance that can reduce carrying roller with grease lubrication, the particularly resistance between two sealing members;
2, the mode by thin oil lubricant can change oil, so just can prolong the bearing service life of carrying roller, the service life of indirect prolongation carrying roller;
This structure adopts the mode of two kinds of labyrinth packings, and a kind of is to constitute by inner seal liner 5, outside seal may 6, and dashing therebetween has thin oil; Another kind is to form another labyrinth packing by enclosing cover 2, seal ring 3, spacer ring 4, pours the purpose that grease reaches waterproof and dustproof in cavity A, C, thereby prolongs the service life of carrying roller.
More than show and described groundwork of the present utility model, principal character and advantage of the present utility model.The technical personnel of the industry should be understood; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification sheets just illustrates principle of the present utility model; the utility model also has various changes and modifications under the prerequisite that does not break away from the utility model spirit and scope, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
