Description
The utility model is a kind of mine hoisting container roller.
Roller is mainly by wheel, rocker, buffering and adjusting mechanism are formed, the wheel construction of roller that known above-mentioned occasion is used is (seeing coal mine machinery equipment type selecting handbook and each originating firm specification manual) at present: the end at an anchor shaft is installed antifriction-bearing box, outer wheel hub in installing on the outside race, seal with plain cushion between the interior outer wheel hub, elastic wheel (material is generally polyurethane) is installed on wheel hub, use single oil sealing sealing between wheel hub and the projecting shaft, the other end adds the plain cushion sealing with end cap, by axle head baffle plate and wheel carrier relative fixed, an axle fixed end is established oil nipple in the projecting shaft insertion turning rolls hole.
The shortcoming of existing roller is: the sealing of roller is unreliable, and the water in the roller working environment, mud, dust and other impurities enter roller inside easily, and antifriction-bearing box is damaged, and roller lost efficacy; Roller and wheel carrier are fixed with the axle head baffle plate, and poor reliability is not easy to the mounting or dismounting and the exchange of gauche form; Oil nipple exposes, and damages easily; Antifriction-bearing box, damages the locking catch easily, thereby withdraws from circular nut when inner ring is followed rotation after the bearing failure with circular nut and the locking of locking catch, causes the wheel accident.
For overcoming the weak point of above-mentioned rollers, the purpose of this utility model provide a kind of seal reliable, that mounting or dismounting are exchanged is convenient, oil nozzle is not fragile, be difficult for falling wheel, roller that the stable operation time is long.
The purpose of this utility model can reach by following structure:
End at axle is installed two antifriction-bearing boxs, and rolling bearing inner ring adds wear washer with circular nut and locked spacer locking between bearing inner ring and locked spacer; Outside race is located by the annular protrusion on the left wheel hub; The left wheel hub left end adds the sealing of O shape circle, bolt up with end cap; Right wheel hub is installed on left wheel hub, is used seal with O ring between the wheel hub of the left and right sides, bolt up; Between the wheel hub of the left and right sides, elastic wheel is installed; The other end of axle stretches out from right wheel hub center, and the two way seal circle is installed between axle and right wheel hub, and the two way seal circle can be integral body or isolating construction; Establish cannelure at right wheel hub right-hand member, fix a circular baffle plate on axle, establish annular protrusion on the circular baffle plate, annular protrusion gos deep into forming in the cannelure labyrinth packing; The outrigger shaft right-hand member is loaded in the turning rolls hole, and outrigger shaft is provided with cannelure, and the lock bolt that groove is used on the turning rolls stretches into locking; Overhanging axle head is established an inward recess, and oil nipple is installed in the hole.
The roller of above-mentioned structure, for obtaining better result of use, the cannelure number of labyrinth packing should be more than two or two, and the wheel edge that projection should be arranged on the wheel hub of the left and right sides is to clamp elastic wheel.
The utility model has following advantage compared to existing technology:
1, sealing is reliable, and the roller stable operation time is long;
2, the mounting or dismounting exchange is convenient, oil nozzle is not fragile;
3, be difficult for falling wheel.
The utility model is described further below with reference to accompanying drawing:
Figure one is the utility model roller shaft cutaway view, wherein: 1-elastic wheel, the right wheel hub of 2-, the right wheel of 2.1-hub wheel edge, 3-left and right sides wheel hub fastening bolt, 4-O shape circle, 5-two way seal circle, 6-baffle plate, 7-axle, 7.1-shrinkage pool, 7.2-cannelure, 8-oil nozzle, 9-wear washer, 10-circular nut and locked spacer, 11-antifriction-bearing box, 12-left wheel hub, 12.1-revolver hub wheel edge, 13-end cap, 14-end cap binding bolt.
The structure and the principle of work of the utility model roller are:
Left end at axle 7 is installed two antifriction-bearing boxs 11, and rolling bearing inner ring adds wear washer 9 with circular nut and locked spacer 10 lockings between bearing inner ring and locked spacer; Outside race is located by the annular protrusion on the left wheel hub 12; The left wheel hub left end adds 4 sealings of O shape circle with end cap 13, and is fastening with end cap binding bolt 14; Right wheel hub 2 is installed on left wheel hub,, fastening between the wheel hub of the left and right sides with left and right sides wheel hub fastening bolt 3 with 4 sealings of O shape circle; Elastic wheel 1 is installed between the wheel hub of the left and right sides; The other end of wheel shaft stretches out from right wheel hub center, and two way seal circle 5 is installed between wheel shaft and right wheel hub, and the two way seal circle can be integral body or isolating construction; Establish cannelure at right wheel hub right-hand member, fix a circular baffle plate 6 on axle, establish annular protrusion on the circular baffle plate, annular protrusion gos deep into forming in the cannelure labyrinth packing; Axle 7 right-hand members are loaded in the turning rolls hole, and outrigger shaft is provided with cannelure 7.2, and the lock bolt that groove is used on the turning rolls stretches into locking; Overhanging axle head is established an inward recess 7.1, and oil nipple 8 is installed in the hole.
For obtaining better result of use, the cannelure number of labyrinth packing is two, and the wheel that left and right sides wheel hub epirelief rises is used to clamp elastic wheel along 2.1 and 12.1.
When the elastic wheel orbiting, friction force drives left and right sides wheel hub, outside race and ball and rotates around bearing inner ring, the positiver sealing of O shape circle and labyrinth and two way seal circle, make extraneous mud, water, dust etc. can not enter in the bearing, the grease or the lubricating fluid of bearing can not leak into the external world simultaneously, bearing is worked under good lubricating condition, and arranged long service life; When causing the bearing inner ring rotation as bearing failure, because wear washer are arranged between bearing inner ring and locked spacer, can prevent the early failure of locked spacer, help the maintenance and inspection personnel and in time find and handling failure, prevent the generation of wheel, material such as wear washer available copper, nylon; Axle is locked with groove is relative with bolt with turning rolls, and it is firm to lock, and safety is good; Left and right sides wheel hub is established wheel along clamping elastic wheel, can prevent that elastic wheel from coming off and pine is spacious, and elastic wheel can be used material manufacture such as rubber, polyurethane elastomer; The oil nozzle that caves in and install, can avoid transporting with environment for use in the direct impact of other object, the protection oil nozzle is not damaged.
The utility model roller if can with the supporting use of patent 99203361.6 rollers, can obtain better result of use.
