Abstract
The utility model relates to an overhead roller chain, designed to solve various defects of current differential chains adopted by the power and free conveyers. Consisting of a pin roll, an inner chain piece, an outer chain piece, a running roller and so on, the utility model is characterized in that both the inner chain piece 3 and the outer chain piece 2 are provided with ear pieces 5 protruding upward, each corresponding ear piece 5 on both sides of the running roller 1 is provided with a power and free roller 4 through the pin roll 6. Furthermore, the ratio of the overall height of the chain to the width of the power and free roller 4 is less than 2. Under the premise that stability is guaranteed, the utility model has the advantages of small occupying space, simple structure, easy manufacturing, moderate manufacturing cost, long service life, and being suitable for various locations. When in use, the work piece is placed on the overhead contact roller for conveying, when the work piece comes to an operation position and the stopper stops the work piece from running, the chain can continue to move with almost no resistance, thereby allowing the power and free work piece to fulfill its function.
Description
Technical field:
The utility model relates to a kind of conveyor chain.
Technical background:
At present, be used for the long-pending chain of putting conveyer of ground chain type and mostly be the differential chain, the major defect of differential chain is: because the long-pending roller housing of putting on the walking roller, therefore causes cross section size on Width to increase, this is very unfavorable for the very nervous environment of this kind equipment usage space.Because the roller of differential chain adopts engineering plastics, though it has supporting aluminum alloy track, makes its production technology good, cost is low, and its intensity, resistance to abrasion and shock resistance are all relatively poor, and the life-span is shorter, and is inapplicable in a lot of occasions; Though and differential chain intensity, resistance to abrasion and the shock resistance of steel are good, but owing to there is not supporting with it aluminum alloy track, therefore want smooth operation must guarantee that the walking roller bearing part that is positioned at the large roller both sides is in same plane, this has not only increased technology difficulty, but also causes cost to rise.
The utility model content:
Task of the present utility model is to provide a kind of overhead roller chain at the problems referred to above, and it is under the prerequisite that guarantees stability, and it is little not only to take up room, and simple in structure, makes easily, and productive costs is moderate, is applicable to various occasions.Technical solution of the present utility model is: a kind of overhead roller chain, constitute by bearing pin, inner chain sheet, outer chain sheet, supporting roller etc., it is characterized in that: said inner chain sheet and outer chain sheet are equipped with upward the auricle of projection, roll in walking all by bearing pin long-pending putting to be set on each corresponding auricles of both sides and to roll.Its whole height is put the ratio of the width that rolls less than 2 with long-pending.Compared with prior art, advantage of the present utility model mainly is: 1. since the whole height of overhead roller chain and the long-pending ratio of putting the width that rolls less than 2, compact conformation and simple, and it is little to take up room, and therefore has good stability; 2. owing to be positioned at long-pending above the overhead roller chain and put to roll with following walking and roll mutually noninterfere, so the track manufacture craft is simple, produce easily, and cost is moderate; 3. the utility model adopts full steel structure, so its intensity, resistance to abrasion and shock resistance are all very excellent, are applicable to various occasions, and long service life.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the section drawing of Fig. 1
The specific embodiment:
As shown in the figure, the utility model provides the overhead roller chain, is rolled formations such as bearing pin 7, inner chain sheet 3, outer chain sheet 2 and walking (supporting) roller 1 by walking.Inner chain sheet 3 wherein and outer chain sheet 2 are equipped with upward the auricle with holes 5 of projection, and roll and all by bearing pin 6 long-pending putting is set on the corresponding auricle 5 of 1 both sides and rolls 4 being positioned at each joint walking.Skew in order to prevent that chain from producing in when operation, here with the whole height of chain with long-pending put roll 4 width the ratio design less than 2.Such chain, owing to be provided with roller free to rotate (promptly long-pending putting rolled) above it, workpiece places on the overhead roller and carries during use, when therefore meeting the operation position by the operation of stopper prevention workpiece, chain can walk on, and does not almost have resistance, thereby realizes the function of the long-pending part of knocking off.
Claims (2)
1. overhead roller chain, constitute by bearing pin, inner chain sheet, outer chain sheet, supporting roller etc., it is characterized in that: said inner chain sheet (3) and outer chain sheet (2) are equipped with upward the auricle (5) of projection, roll in walking all to be provided with to amass to put by bearing pin (6) on each corresponding auricle (5) of (1) both sides and roll (4).
2. according to the overhead roller chain of claim 1, it is characterized in that: whole height is put the ratio of the width that rolls (4) less than 2 with long-pending.
