The utility model has the advantages of simple technology, simple structure, convenient installation and maintenance, light weight, high intensity, small power consumption, corrosion resistance, abrasion resistance, low cost, long service life, etc.

Description

Integrated link joint driving chain

The utility model relates to a kind of mechanical chain, particularly relates in the industries such as a kind of oil, chemical industry, environmental protection and the matching used mechanical chain of sewage disposal device.

At present, with matching used mechanical transmission chains of sewage disposal device such as scraper, oil skimming machines, be by solid shaft pass respectively symmetrically arranged two outside outer plate, near sleeve, the roller of two inner plates of outer plate inboard and clamping between two inner plates, and roll riveting is carried out in the solid shaft end connect and form.This chain all adopts Structural Hardware, complex structure not only, the installation and maintenance trouble, the mechanical wear to sprocket wheel during work is serious, and perishable, the life-span is short, power consumption is big.

The purpose of this utility model is that the integral type carrier bar drive chain that a kind of simple in structure, installation and maintenance are convenient, mechanical wear is little, anticorrosive, the life-span is long and power consumpiton is little will be provided.

The purpose of this utility model is achieved in that this model utility is that inner plate, outer plate, sleeve, roller are combined together, by two straight chain plates of the end of the chain in being respectively equipped with and the outer end of the chain and a plurality of identical two straight chain plate cranked plates through chain rivet, the hinge that constitutes of lock pin connection only.Narrow in the middle of its straight chain plate, both sides are by narrow gradually wide, and the end is a circular arc.The stiffening rib of projection is arranged along the plate both sides, and two end part center of arc is provided with axis hole.Evagination, the interior semi-convex half recessed pylon that is interlocked are set along the hole between inboard corresponding axis hole wall of the end of the chain and circular arc, and the axis hole external symmetry of end of the chain outside correspondence is provided with projection and has the T shape head of chamfering two outside in two straight chain plates.Its cranked plate is to widen by in the middle of straight chain plate one side, vertically establishes a flat board again, is arranged with the dunnage perpendicular with this flat board at dull and stereotyped two ends.This cranked plate and straight chain plate are engineering plastics and are injection molded into one.Its chain rivet is a metal hollow axle, and its end is provided with and straight, the corresponding T shape head in the cranked plate outer end of the chain outside, and the other end symmetry is established the hole.It ends lock pin is that elastomeric plastics is made, and whole pin becomes " T " font, and there is an opening at the pin center, and the end respectively is a hemisphere.

Because carrier bar of the present utility model adopts engineering plastics injection molded, in one, makes this model utility technology, simple in structure with multi-functional, installation and maintenance are convenient, and have in light weight, intensity is high, anticorrosive, wear-resistant, advantage such as cost is low, the life-span is long.

Accompanying drawings embodiment:

Fig. 1 is the structural front view of integral type carrier bar drive chain;

Fig. 2 is the structure plan view of integral type carrier bar drive chain;

Fig. 3 is the only detent configuration schematic representation of integral type carrier bar drive chain.

By Fig. 1-integral type carrier bar drive chain shown in Figure 3, be through chain rivet 3, the hinge that constitutes of lock pin 4 connections only by two blocks of straight chain plates 1 of the end of the chain 5 in being respectively equipped with and the outer end of the chain 6 and a plurality of identical two blocks of straight chain plates 1, cranked plate 2.Narrow in the middle of its straight chain plate 1, both sides are by narrow gradually wide, and two end part are the garden arc.The stiffening rib 7 of projection is arranged along the plate both sides, and arc center, garden, two end part respectively is provided with axis hole 8 and 9.In two blocks of straight chain plates 1, evagination is set, interiorly is the semi-convex half recessed pylon that is interlocked 10 that corresponding axis hole 9 external symmetrys in the outside of the end of the chain 6 are provided with projection and have the T shape 11 of chamfering outside two blocks of straight chain plates 1 between the hole wall of the inboard corresponding axis hole 8 of the end of the chain 5 and this garden, end arc along axis hole 8.Its cranked plate 2 is by widening in the middle of straight chain plate 1 one sides and vertically establish a flat board 12, being symmetrical arranged dunnage 13 formations perpendicular with dull and stereotyped 12 at dull and stereotyped 12 two ends.This cranked plate 2 all adopts the engineering plastics single injection-molded with straight chain plate 1.

Earlier two blocks of straight chain plates 1, two cranked plates 2 or a straight chain plate 1 are coated mighty bond with cranked plate 2 each convex-concave surface of contact that the pylon 10 of the end of the chain 5 projectioies is interlocked two in respectively during assembling, and corresponding fastening is bonding firm.Corresponding one by one the communicating of axis hole 9 on the outer end of the chain 6 of the axis hole 8 on the interior end of the chain 5 of the two straight chain plates 1 that will glue again and other two straight chain plates 1, its position is that the two interior end of the chains 5 are interior, the outer end of the chain 6 outside, outside one, insert chain rivet 3 in the axis hole 9 of the end of the chain 6, and through the axis hole 9 of axis hole 8 end of the chain 6 to another outside of the interior end of the chain 5 make the T shape head of chain rivet 3 one ends lucky with straight chain plate 1 outside outside the axis hole 9 of the end of the chain 6 set T shape 11 corresponding, and be close to.In the symmetrical holes of chain rivet 3 the other ends, penetrate only lock pin 4.Repeat with chain rivet 3, end lock pin 41 connection of straight chain plate, while is according to the needs of user installation annex, peg graft two cranked plates 2 or the double-stranded plate formed of carrier bar 1 and a cranked plate 2 always, this two strands plate is identical with the outer end of the chain 6 structures with the interior end of the chain 5 of straight chain plate 1, assembles also identical.With connecting pin the chain two ends is connected and fixed at last.
