Description

Roller

Technical field

The utility model belongs to the device that the mine hoisting container is used, particularly the roller of using about the vertical shaft hoisting container.

Background technology

Roller is used for reducing collision and the friction of lifting container at the vertical lifting process, and play the directional tagging of lifting container, often impact between existing roller and the cage guide, seal bearing lubrication in the bad pair roller bad, inconvenient, cause bearing fragile, elasticity is bad, even has the situation of wheel to take place.

Summary of the invention

The purpose of this utility model is in order to overcome the problem that existing roller exists, and a kind of reliable, lubricated convenient, novel roller of being difficult for falling fixing easy to assemble, the long service life between wheel, wheel shaft and the rotation arm that seals is provided.

Technical solution of the present utility model is: by main shaft (5) and be installed in bearing (8) on the main shaft (5), fixed type bearing outer ring about seize tapering wheel (16), right end cap, the integral type shaft shoulder on both sides by the arms, elastic body (6) is formed; It is characterized in that the elongation end of main shaft (5) and the bearing of rotation arm are taper shaft, and establish a pit thereon, left end has the big shaft shoulder (13) and blocks outside race, bearing inner ring (14) is fixed under the effect of jam nut (4), be equipped with a left side in the outer ring of bearing (8) and seize wheel hub (16) on both sides by the arms, and be set with the right side in its cylinder outer ring and seize wheel hub (1) on both sides by the arms, the internal thread hole of seizing wheel hub by an adjusting nut (9) and a left side on both sides by the arms is integrated the two, seizing wheel hub (1) (16) on both sides by the arms about reaching by the predetermincd tension of regulating bolt (9) inwardly concentrates, under the effect on its wheel hub (1) double tapered disc and wheel edge, make the elastic body (6) that is enclosed within on the outer ring in axial compression and radial dilatation, reach the purpose of tensioning elastic body (6), improve for the intensity that makes elastic body (6) in addition, in elastic body (6), be provided with two jiaos of bands (7) near near the clamping wheel hub (1), right in addition cramping body (1) is equipped with one-way sealing circle (2) and exclusion seal device (3) near the position of main shaft (5), be provided with priming cup (11) and pilot hole makes lubricating oil arrive the inside of bearing (8) with the shortest distance at the left end of main shaft (5), no air pressure, it is last and fixing with end cap (12) with nut (15) that the inner ring of right wheel hub buckles the outer ring (16) of seizing the wheel hub cylinder on a left side on both sides by the arms in addition.And, between right wheel hub (16) and left wheel hub (16) the awl end and between left wheel hub (16) cylinder end face and right wheel hub (16) inner end surface, leave certain interference clearance that screws; And a left side seizes on both sides by the arms to take turns to hold to establish between evagination end cap (12) and the wheel cap grease sealing, links with nut (15) and logical bolt (9); End cover (12) is established one recessed hole, screws in and sealing with plug, and when opening sealing, the filler port of left shaft shoulder end [being priming cup (11)], this design helps to make things convenient for oil injecting lubricating; Simultaneously, roller outrigger shaft and rocker bearing are the tapering face; And right wheel hub (16) and axle are sealed into interference one-way sealing (2) between (5), thereby have guaranteed the leak free reliability, have prolonged bearing service life.

Roller of the present utility model is compared with existing product, and the sealing of product has directivity.During the roller normal operation, can seal overflowing of grease, if when pressurizeing with nozzle, in the bearing bore, no air pressure, fresh oil is easily gone into, waste oil easily goes out, and lubricant effect is better, and is more reliable, make and obtain actv. in service life of product and improve, the design of the big shaft shoulder prevents wheel, has guaranteed reliability of products from structure, and maintaining is convenient, about seize some long nuts of body and function on both sides by the arms and fix, improved elastomeric stability and reliability largely.

The specific embodiment

Those skilled in the art will appreciate that in conjunction with the accompanying drawings, the utility model is by a rigidity main shaft (5) and be enclosed within bearing inner ring (14) and the bearing (8) on the main shaft (5) and be enclosed within a left side on the outer ring of bearing (8) and seize wheel hub (16) and the cover right side thereon on both sides by the arms and seize wheel hub (1) on both sides by the arms and be enclosed within two elastic bodys (6) of seizing on both sides by the arms on the wheel hub outer and formed, left end at axle (5) disposes priming cup (11) and the oiling duct in main shaft (5) left end, lubricating oil is sent in the bearing (8) very quickly, about to seize wheel hub (16) (1) and end cap (12) on both sides by the arms be fixing with whole bolt (9) and nut (15), and dispose seal cover cap (10) to make things convenient for the lubricated of bearing (8) at end cap center shrinkage pool.Bearing (8) is fixed by the big shaft shoulder of main shaft (5) left end (13) and jam nut (4) and regulates, and the position of seizing the close main shaft (5) of wheel hub (1) on a left side on both sides by the arms is provided with one-way sealing circle (2) and dust-proof seal ring (3).The bolt (9) of seizing wheel hub about in addition, fixing on both sides by the arms is one whole and has the bolt (9) of axial tapering.The straight bucket outer ring that has a left side to seize wheel hub (16) on both sides by the arms again is to be enclosed within that the right side is seized on both sides by the arms on the straight bucket inner ring of wheel hub (1), above-mentioned priming cup (11) is a press-fit priming cup (11), establish a pit on the tapering face of main shaft (5) in addition, with swing arm fixing after, be screwed into bolt (9) to limit its unusual moving axially and radially rotating.
