Abstract
Large -tonnage is chain for pinch roller, it is mainly formed with connecing the round pin to concatenate by a plurality of chain links in proper order, the chain link constitute by left chain link unit and right chain link unit, wherein left chain link unit has a step connection piece that expands in two external contractings, contract to have inserted and put a roller between the piece and worn the cover at the roller centre bore and have the sleeve in the outside of this step connection piece, these telescopic both ends are fixed respectively in piece sleeve bore is contracted in the outside of step connection piece, the both sides of step connection piece are expanded a side that inserts and puts an annex between the piece and are used simultaneously and meet round pin company of wearing, and the tip of the company of wearing between two outer plates of right chain link unit is sold through connecing to another side of this annex, the chain link tip of two chain links is that two outer plates through a chain link insert and put and contract the piece outside with after connecing the round pin to pass the sleeve centre bore at two of another adjacent chain link, contracts and be formed by connecting after piece and outer plate pass in the both ends that connect round pin follow both sides adjacent respectively.
Description
Technical field
The utility model relates to a kind of large-tonnage pinch roller chain, belong to drive chain technical field.
Background technique
Chain is a kind of multi-purpose machinery driving component being 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 primarily of element compositions such as outer plate, internal sheet, bearing pin, sleeve and rollers; But the roller chain of this basic structure is not suitable for large-tonnage pinch roller to be used, reason is that the driving force that large-tonnage pinch roller bears is comparatively large, and existing common drive chain cannot bear so large moment, often easily weares and teares or insufficient strength, cause rapid wear, directly affect the transmission of large-tonnage pinch roller.
Summary of the invention
The purpose of this utility model is for the problems referred to above, and provide a kind of reasonable in design, structure is simple, uses reliable and secure, and intensity is large, and uniform force, long service life, can improve the large-tonnage pinch roller chain of equipment use efficiency.
The purpose of this utility model has been come by following technical solution, a kind of large-tonnage pinch roller chain, it forms with connecing pin serial connection successively primarily of multiple chain link, described chain link is made up of left link units and right link units, wherein left link units has the stepped shape connecting sheet expanded in two panels external contracting, be gripped with a roller between the outside contracting sheet of this stepped shape connecting sheet and be coated with sleeve in roller centre hole, the two ends of this sleeve are separately fixed in the outside contracting sheet sleeve hole of stepped shape connecting sheet;
Be gripped with a side of an annex between the both sides spread sheet of stepped shape connecting sheet and wear connect with connecing pin, another side of this annex is by the end that connects pin and wear between two outer plates being connected in right link units;
The link end of described two chain links be interposed in another adjacent link by two outer plates of a chain link two contracting sheets outside with connecing pin through behind bushing core hole, the two ends connecing pin are formed by connecting respectively after the adjacent contracting sheet of both sides and outer plate pass.
As preferably: described annex is a rectangular blocks, its dual-side offer respectively for connect pin wear connect connect pin-and-hole, the top of described rectangular blocks is provided with protruding pressure roller structure; The semicircle diameter of described chain link contracting sheet end is greater than the semicircle diameter of another spread sheet end.
The utility model belongs to the improvement to prior art, and it has reasonable in design, and structure is simple, uses reliable and secure, and intensity is large, and uniform force, long service life, can improve the features such as equipment use efficiency.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 be Fig. 1 look up structural representation.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail: shown in Fig. 1,2, a kind of large-tonnage pinch roller chain described in the utility model, it forms with connecing pin 4 serial connection successively primarily of multiple chain link, described chain link is made up of left link units and right link units, wherein left link units has the stepped shape connecting sheet 7 expanded in two panels external contracting, be gripped with a roller 5 between the outside contracting sheet 71 of this stepped shape connecting sheet 7 and be coated with sleeve 6 in roller centre hole, the two ends of this sleeve 6 are separately fixed in outside contracting sheet 71 sleeve hole of stepped shape connecting sheet 7;
A side of an annex 2 is gripped with and with meeting pin 4 company of wearing, another side of this annex 2 is by the end that connects pin 4 and wear between two outer plates 3 being connected in right link units between the both sides spread sheet 72 of stepped shape connecting sheet 7;
The link end of described two chain links be interposed in another adjacent link by two outer plates 3 of a chain link two contracting sheets 71 outside with connecing pin 4 through after sleeve 6 center hole, the two ends connecing pin 4 are formed by connecting respectively after the adjacent contracting sheet 71 of both sides and outer plate 3 pass.
Shown in figure, annex 2 described in the utility model is a rectangular blocks, and its dual-side offers respectively and connects pin-and-hole for what meet pin 4 company of wearing, and the top of described rectangular blocks is provided with protruding pressure roller structure 1; The semicircle diameter of described chain link contracting sheet 71 end is greater than the semicircle diameter of another spread sheet 72 end.
