Abstract

Transmission chain, it is mainly met in proper order by a plurality of chain links and constitutes, the chain link including: about two, every both ends inner plate on semicircular in shape limit respectively, after both ends between two inner plates insert and put the roller respectively and wear the centre bore of roller even with the sleeve, both ends fix respectively in inner plate sleeve bore, other has two outer plates to insert and put respectively a tip of two inner plates passes through the pivot that sleeve hole, its both ends pass the inner plate respectively and the outer plate will an end connection of outer plate is in on the inner plate, the U type connection piece of two outer plates through upper portion meet together, and the last transverse plane of U type connection piece is placed in the chain drive orientation to one side, two outer plates and upper portion as an organic whole the making of U type connection piece of meeting, the transverse plane is 120 degrees angles with the chain drive orientation and arranges on the U type connection piece, and is provided with two connecting holes at this shang on the transverse plane, it is reasonable, simple that it has structural design, long service life, characteristics such as ability improve equipment availability factor.

Description

Driving chain

Technical field

The utility model relates to a kind of driving chain, belongs to mechanical transmissioning technology field.

Background technology

In existing industrial production streamline, use in large quantities driving chain as important drive disk assembly, this driving chain is a kind of multi-purpose machinery driving member that is made up of flexible system rigid member, is mainly used in meeting the functional requirements such as transmission, conveying, towing. Wherein, roller chain is a kind of widely used chain type, and it is mainly made up of elements such as outer plate, interior, pivot pin, sleeve and rollers. But in some comparatively special application scenarios, the roller chain of this routine cannot be suitable for simply, because in some special use occasion, driving-chain not only needs to carry out the transmission of object, and need to bear certain bearing capacity, therefore driving-chain maximum problem is exactly wearing and tearing or the distortion how reducing in transmission process, because exist above-mentioned two problems will cause the reduction greatly in its service life, thereby has influence on the operating efficiency of transmission equipment.

Summary of the invention

The purpose of this utility model is for the problems referred to above, and a kind of reasonable in design, simple is provided, easy to use and reliable, safe, and long service life can improve the driving chain of equipment service efficiency.

For achieving the above object, the utility model has adopted following technical proposal: a kind of driving chain, it is mainly joined and forms successively by multiple chain links, described chain link includes: two of left and right, the every both ends interior sheet on semicircular in shape limit respectively, both ends between two interior are gripped with respectively roller and wear with sleeve after the centre bore that connects roller, two ends are separately fixed in interior sleeve hole, separately there are two outer plates to be interposed in respectively an end of described two interior, pass sleeve endoporus by pivot pin, its two ends are connected to an end of described outer plate on described interior with outer plate through interior respectively,

Two described outer plates are connected together by the U-shaped brace on top, and the upper transverse plane of U-shaped brace is inclined in chain drive direction.

As preferably: the U-shaped brace that two described outer plates and top join is integrated to be made, on U-shaped brace, transverse plane and chain drive direction are 120 degree angles and arrange, and on this, on transverse plane, are provided with two connecting holes.

As preferably: be mounted with an O type circle being nested with on pivot pin between described interior sheet and outer plate, described pivot pin one end adopts heading structure, and the other end adopts cubic riveting knot structure; The centre of described outer plate 1 is also provided with an outer projection 7.

The utility model belongs to improvements over the prior art, and it has reasonable in design, simple, and easy to use and reliable, safe, long service life, can improve the features such as equipment service efficiency.

Fig. 2 is side-looking structural representation of the present utility model.

Detailed description of the invention

Below in conjunction with accompanying drawing, the utility model is described in detail. Fig. 1, shown in 2, a kind of driving chain described in the utility model, it is mainly joined and forms successively by multiple chain links, described chain link includes: two of left and right, the every both ends interior sheet 2 on semicircular in shape limit respectively, both ends between two interior 2 are gripped with respectively after roller 3 centre bore with sleeve 4 company's of wearing rollers 3, two ends are separately fixed in interior 2 sleeve holes, separately there are two outer plates 1 to be interposed in respectively an end of described two interior 2, pass sleeve 4 endoporus by pivot pin 6, its two ends are connected to an end of described outer plate 1 on described interior 2 through interior 2 and outer plate 1 respectively,

Two described outer plates 1 are connected together by the U-shaped brace 11 on top, and the upper transverse plane 12 of U-shaped brace 11 is inclined in chain drive direction.

Shown in figure, the U-shaped brace 11 that two outer plates 1 described in the utility model and top join is integrated to be made, and upper transverse plane 12 and the chain drive direction of U-shaped brace 11 is 120 degree angles arranges, and on this, on transverse plane 12, is provided with two connecting holes 13.

Between interior 2 and outer plate 1 described in the utility model, be mounted with an O type circle 5 being nested with on pivot pin 6, this O type circle 5 can make driving-chain described in the utility model under rugged environment, improves the service life of driving-chain; Pivot pin described in the utility model 6 one end adopt heading structure 61, and the other end adopts cubic riveting knot structure 62; The centre of described outer plate 1 is also provided with an outer projection 7.
