Description

supporting rollers convenient for maintenance

Technical Field

The utility model belongs to the technical field of conveyer bearing roller subassembly, concretely relates to kinds of bearing rollers of maintenance of being convenient for.

Background

The rubber belt conveyor is common equipment in the lifting and transporting industry, the carrier roller is an important component of the rubber belt conveyor, the carrier roller is applied to the open air, large dust and high-corrosiveness severe environments such as mining, chemical industry, coking, steel, thermoelectricity, coal washing, cement, metallurgy and other industries, at present, most of domestic carrier rollers are permanently sealed (the carrier roller cannot be maintained after being assembled), and the main defect of the carrier roller is that under special use conditions (high temperature and high speed), lubricating grease in a bearing of the carrier roller can permeate and dry, so that the service life of the carrier roller is seriously damaged and shorter, and the normal operation and the conveying efficiency of the conveyor are seriously influenced by adverse factors.

SUMMERY OF THE UTILITY MODEL

To the problem among the prior art, the utility model discloses a provide open bearing rollers, can lubricate in real time to can prevent that emollient from drying out.

In order to achieve the above purpose, the technical scheme of the utility model is that:

bearing roller convenient to maintenance, including axis of rotation and roll body, be equipped with the bearing frame in the roll body inner race, be equipped with the bearing between axis of rotation and the bearing frame, the bearing inner race is worn to establish by the axis of rotation, the bearing outside is equipped with the seal assembly who is located between axis of rotation and the bearing frame, seal assembly includes the bottom sealing washer, the axle sleeve, axle sleeve sealing washer and sealed enclosing cover, the bottom sealing washer sets up in the side of bearing along the axial of bearing roller, the axle sleeve, axle sleeve sealing washer and sealed enclosing cover set up in the other side of bearing along the axial of bearing roller, and the axle sleeve, axle sleeve sealing washer and the coaxial setting of sealed enclosing cover, the axle sleeve forms the oil storage tank with the bearing side, the side that the axle sleeve.

Step , the width of the protrusion is the same as the difference between the inner and outer diameters of the bearing.

, the position of the protrusion is matched with the position of the bearing ball.

, reinforcing sleeves are arranged between the bottom sealing ring and the bearing and between the bearing seat and the bearing.

, pairs of snap springs are arranged in the oil storage tank and are respectively arranged on the side surface of the bearing and the side surface of the shaft sleeve, and the snap springs are clamped on the rotating shaft.

Compared with the traditional totally enclosed bearing roller, the utility model discloses a set up oil storage tank and oiling mouth, can pour into emollient into to the bearing in real time, avoid emollient consumption, muddy and infiltration can't in time supply the bearing wear who causes, through set up the arch in the axle sleeve side, can stir the emollient in the oil storage tank in axis of rotation pivoted, prevent emollient dry knot, bellied position and ball position looks adaptation, in protruding pivoted, can be with in the better roll of dialling of emollient, make lubricated effect better, advance step and set up the reinforcing cover, fixing bearing that can be better, the utility model discloses can lubricate in real time to can prevent emollient dry knot.

Drawings

In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings needed to be used in the description of the embodiments or the prior art will be briefly described below, it is obvious that the drawings in the following description are only the embodiments of the present invention, and for those skilled in the art, other drawings can be obtained according to the drawings without creative efforts.

FIG. 1 is a schematic structural view of the present invention;

figure 2 is the structure schematic diagram of the middle shaft sleeve of the utility model.

In the figure: 1. the roller comprises a roller body 2, a bearing seat 3, a sealing outer cover 4, a shaft sleeve sealing ring 5, a shaft sleeve 5-1 bulge 6, an oil injection port 7, a rotating shaft 8, a bearing 9, a bottom sealing ring 10, a reinforcing sleeve 11, an oil way 12 and an oil storage tank.

Detailed Description

It is to be understood that the embodiments described are merely exemplary embodiments , rather than all exemplary embodiments, and that all other embodiments obtained by those skilled in the art without any inventive step are within the scope of the present invention.

As shown in fig. 1 and 2, carrier rollers convenient for maintenance comprise a rotating shaft 7 and a roller body 1, a bearing seat 2 is arranged in an inner ring of the roller body 1, a bearing 8 is arranged between the rotating shaft 7 and the bearing seat 2, the rotating shaft 7 penetrates through the inner ring of the bearing 8, a sealing assembly located between the rotating shaft 7 and the bearing seat 2 is arranged outside the bearing 8, the sealing assembly comprises a bottom sealing ring 9, a shaft sleeve 5, a shaft sleeve sealing ring 4 and a sealing outer cover 3, the bottom sealing ring 9 is arranged on a side of the bearing 8 along the axial direction of the carrier roller, the shaft sleeve 5, the shaft sleeve sealing ring 4 and the sealing outer cover 3 are arranged on the other side of the bearing 8 along the axial direction of the carrier roller, the shaft sleeve 5, the shaft sleeve sealing ring 4 and the sealing outer cover 3 are coaxially arranged, an oil storage groove 12 is formed by the side surfaces of the shaft sleeve 5 and the bearing 8, a bulge 5-1 is arranged on a side of the shaft sleeve 5 located in the oil storage groove 12, an oil injection port 6 is arranged at the end of the rotating shaft 7, the oil storage groove 6 is communicated with the oil passage 11, the bulge 5-1 has the same width as the position of the ball of the bearing 8, a position matched with the position of the ball bearing.
