Abstract
The utility model discloses a kind of wear-resisting type chain and chain-plate, comprise the Chain plate that more piece is connected successively, wherein, described every pitch chain batten comprises two outer plates be oppositely arranged and two inner plates be oppositely arranged, and described outer plate is positioned at the outside of inner plate; Be connected by bearing pin between described two adjacent outer plates and inner plate, be provided with sleeve outside described bearing pin, between described inner plate and sleeve, interference connects.Interference connection between inner plate of the present utility model and sleeve and the two ends of sleeve exceed inner plate both sides outward edge size 0.5 ~ 1mm respectively; make to leave space between inner plate and outer plate while the reliable connection of guarantee; greatly reduce the friction area between interior outer plate; protect inner plate, thus increase the working life of chain.In addition, the endoporus of interior outer plate of the present utility model is all set to flattened oval hole, and adjacent with sleeve connection by the bearing pin with flattened oval shape head in outer plate, can ensure that bearing pin and sleeve do not rotate at chain plate hole internal fixtion better, and installing/dismounting is very convenient.
Description
Technical field
The utility model relates to a kind of chain and chain-plate, particularly relates to a kind of wear-resisting type chain and chain-plate.
Background technique
Chain is the strength member of board chain hoisting machine, with plate chain as traction enhancement conveying industries, bearing pin, sleeve and the interior outer plate connected separately are fixing can not works in relative rotation, and if any relatively rotating, chain plate hole will soon be large and cause carrier bar to come off chain inefficacy by mill.There are large size wearing and tearing between the interior outer plate of existing chain, therefore shorten the life-span of chain.In addition, existing circular hole carrier bar causes because the reasons such as machining error are easy to make bearing pin and sleeve to loosen and relatively rotates, and processing method carrier bar easily produces stress concentration point at the endoporus of the carrier bar of circular hole routinely, cause carrier bar to ftracture through stress concentration point of being everlasting in actual use and cause equipment accident.
Model utility content
Technical problem to be solved in the utility model is to provide a kind of wear-resisting type chain and chain-plate, can greatly reduce the friction area between interior outer plate, protection inner plate, thus increases the working life of chain.
The utility model is solve the problems of the technologies described above the technological scheme adopted to be to provide a kind of wear-resisting type chain and chain-plate, comprise the Chain plate that more piece is connected successively, wherein, described every pitch chain batten comprises two outer plates be oppositely arranged and two inner plates be oppositely arranged, and described outer plate is positioned at the outside of inner plate; Be connected by bearing pin between described two adjacent outer plates and inner plate, sleeve is provided with outside described bearing pin, between described inner plate and sleeve, interference connects, and is interference fit and exceeds inner plate outward edge size 0.5mm ~ 1mm at the outer barrel of inner plate between described inner plate and sleeve.
Above-mentioned wear-resisting type chain and chain-plate, wherein, the two ends of described outer plate and inner plate are flattened oval shape, and described outer plate and inner plate are equipped with flattened oval hole; The head of described bearing pin and sleeve is flattened oval shape, and head and the described flattened oval hole of described bearing pin and sleeve match.
The utility model contrast prior art has following beneficial effect: the wear-resisting type chain and chain-plate that the utility model provides; between described inner plate and sleeve, interference connects and exceeds inner plate outward edge size 0.5mm ~ 1mm at the outer barrel of inner plate; make to leave space between inner plate and outer plate while the reliable connection of guarantee; greatly reduce the friction area between interior outer plate; protect inner plate, thus increase the working life of chain.In addition, the endoporus of interior outer plate of the present utility model is all set to flattened oval hole, thus generation stress can be avoided to concentrate and cause carrier bar to ftracture or fracture, outer plate in adjacent with sleeve connection by the bearing pin with flattened oval shape head, can ensure that bearing pin and sleeve do not rotate at chain plate hole internal fixtion better, and installing/dismounting is very convenient.

Embodiment
Below in conjunction with drawings and Examples, the utility model will be further described.
Fig. 1 is the utility model wear-resisting type chain and chain-plate structural representation one; Fig. 2 is the utility model wear-resisting type chain and chain-plate structural representation two.
Refer to Fig. 1 and Fig. 2, the wear-resisting type chain and chain-plate that the utility model provides comprises the Chain plate that more piece is connected successively, wherein, described every pitch chain batten comprises two outer plates be oppositely arranged 4 and two inner plates be oppositely arranged 2, and described outer plate 4 is positioned at the outside of inner plate 2; Be connected by bearing pin 1 between described two adjacent outer plates 4 and inner plate 2, be provided with sleeve 3 outside described bearing pin 1, between described inner plate 2 and sleeve 3, interference connects.Described sleeve 3 is preferably 0.5mm ~ 1mm than the length protruded outside inner plate 2.
The wear-resisting type chain and chain-plate that the utility model provides; between described inner plate 2 and sleeve 3, interference connects; after inner plate 2 and sleeve 3 interference fit; the two ends of sleeve 3 exceed inner plate both sides outward edge size 0.5 ~ 1mm respectively; make to leave 0.5 ~ 1mm space between inner plate 2 and outer plate 4 while the reliable connection of guarantee; greatly reduce the friction area between interior outer plate, protect inner plate 2.During concrete assembling inner plate 2 and the first elastic conjunction of sleeve 3 integral, in using process, inner plate 2 does not have relative movement with sleeve 3.In use outer plate 4 only amasss with the end facets of sleeve 3 and contacts and have relative rotation, and inner plate 2 can not be made to wear and tear.
The wear-resisting type chain and chain-plate that the utility model provides, wherein, the two ends of described outer plate 4 and inner plate 2 are flattened oval shape, and described outer plate 4 and inner plate 2 are equipped with flattened oval hole; The head of described bearing pin 1 and sleeve 3 is flattened oval shape, head and the described flattened oval hole of described bearing pin 1 and sleeve 3 match, thus generation stress can be avoided to concentrate and cause carrier bar to ftracture or fracture, and adjacent interior outer plate is connected with sleeve 3 by the bearing pin 1 with flattened oval shape head, thus ensure that bearing pin 1 and sleeve 3 do not rotate at chain plate hole internal fixtion, and installing/dismounting is very convenient.
Although the utility model discloses as above with preferred embodiment; so itself and be not used to limit the utility model; any those skilled in the art; not departing from spirit and scope of the present utility model; when doing a little amendment and perfect, therefore protection domain of the present utility model is when being as the criterion of defining with claims.
