Abstract
The utility model discloses a maintenance-free type outer roller plate chain. A pin shaft is inserted to a connecting chain plate, an outer roller is arranged on the pin shaft in a sleeved mode and located on the outer side of the connecting chain plate, and a rolling bearing is arranged between the outer roller and the pin shaft. According to the maintenance-free type outer roller plate chain, abrasion of the chain can be reduced, the service life of the chain is prolonged, lubrication is of no need, material pollution is avoided, and energy consumption is lowered.
Description
Technical field
The utility model relates to material equipment, is specifically related to the outer roller plate chain of a kind of non-maintaining type.
Background technology
What on chain scraper reclaimer equipment, generally adopt at present is interior roller chain, between the bearing pin of interior roller and connection carrier bar, there is no bearing and sealing, dust in bulk cargo or fine particle easily enter in the gap between them, cause serious wearing and tearing, have greatly dwindled the service life of chain.In chain operational process, in order to guarantee interior roller normal rotation, need a large amount of continuous lubrications, the lubricating oil of drippage can pollute material.Between roller and bearing pin and carrier bar, be cliding friction, friction force is large, has increased energy consumption.
Utility model content
Technical problem to be solved in the utility model be between roller and bearing pin and carrier bar for cliding friction, friction force is large, has increased energy consumption, and needs a large amount of continuous lubrications, the problem that the lubricating oil of drippage can pollute material.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopts is to provide the outer roller plate chain of a kind of non-maintaining type, connect on carrier bar and be inserted with bearing pin, outer roller housing is on described bearing pin and be positioned at the outside that connects carrier bar, between described outer roller and bearing pin, is provided with antifriction-bearing box.
Outside above-mentioned non-maintaining type, in roller plate chain, described antifriction-bearing box right-hand member is provided with double-layer labyrinth type all-metal sealing.
Outside above-mentioned non-maintaining type in roller plate chain, described antifriction-bearing box is to be provided with spacer ring between two deep groove ball bearings being arranged side by side of left and right and the two.
Outside above-mentioned non-maintaining type, in roller plate chain, on described bearing pin, cover has axle sleeve, and described antifriction-bearing box is fixed on the outside of described axle sleeve.
Outside above-mentioned non-maintaining type, in roller plate chain, between described axle sleeve and bearing pin and between axle sleeve and the inner ring of antifriction-bearing box, be respectively equipped with binding ring.
Outside above-mentioned non-maintaining type, in roller plate chain, the right-hand member of the joint face of described bearing pin and axle sleeve is provided with small circular seal ring.
Outside above-mentioned non-maintaining type, in roller plate chain, the left part of described outer roller inner side is fixed with the circular end cap that covers its through hole.
Outside above-mentioned non-maintaining type, in roller plate chain, the left end at described end cap edge is against there being a binding ring, and described binding ring is fixed in the groove of described outer roller inner side.
Outside above-mentioned non-maintaining type, in roller plate chain, the right-hand member at described end cap edge is provided with a large circular seal ring.
Outside above-mentioned non-maintaining type in roller plate chain, described axle sleeve and connect between carrier bar and be respectively equipped with spacer ring between antifriction-bearing box and end cap.
The outer roller plate chain of non-maintaining type that the utility model provides can reduce the wearing and tearing of chain, improves service life, and without lubricated, avoids the pollution to material, reduces energy consumption.
Accompanying drawing explanation
The structural representation of the outer roller plate chain of non-maintaining type that Fig. 1 provides for the utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail.
As shown in Figure 1, on the connection carrier bar 5 of the outer roller plate chain of non-maintaining type that the utility model provides, be inserted with bearing pin 8, outer roller 9 is enclosed within on bearing pin 8 and is positioned at the outside that connects carrier bar 5, between outer roller 9 and bearing pin 8, be provided with antifriction-bearing box 1, between two deep groove ball bearings that antifriction-bearing box 1 is arranged side by side for left and right and the two, be provided with spacer ring 13, antifriction-bearing box 1 right-hand member is provided with double-layer labyrinth type all-metal sealing 14, during assembling, in institute is gapped, all fills long-life, high-temperature bearing special grease.
On bearing pin 8, cover has axle sleeve 10, and antifriction-bearing box 1 is fixed on the outside of axle sleeve 10, between axle sleeve 10 and bearing pin 8 and between axle sleeve 10 and the inner ring of antifriction-bearing box 1, is respectively equipped with binding ring 2, and the right-hand member of the joint face of bearing pin 10 and axle sleeve 10 is provided with small circular seal ring 15.
The left part of outer roller 9 inner sides is fixed with the circular end cap 11 that covers its through hole, and the left end at end cap 11 edges is against there being a binding ring 3, and binding ring 3 is fixed in the groove of outer roller 9 inner sides, and the right-hand member at end cap 11 edges is provided with a large circular seal ring 16.
The utility model adopts the structure design of outer roller, between bearing pin 8 and outer roller 9, add antifriction-bearing box 1, change cliding friction is friction of rolling, between bearing pin 8 and outer roller 9, add actv. sealing, owing to having bearing and effective sealing between roller and bearing pin, can guarantee that outer roller freely rotates, and can prevent entering of dust again; At the lifelong actv. grease of surrounding's filling of antifriction-bearing box 1, avoid extra lubricating.
The outer roller plate chain of non-maintaining type that the utility model provides can reduce the wearing and tearing of chain, improves service life, and without lubricated, avoids the pollution to material, reduces energy consumption.
The utility model is not limited to above-mentioned preferred forms, and anyone should learn the structural change of making under enlightenment of the present utility model, every with the utlity model has identical or close technical scheme, within all falling into protection domain of the present utility model.
