Abstract
The utility model discloses a hollow pin shaft chain, and belongs to the technical field of transmission mechanical parts. The hollow pin shaft chain comprises inner plates, outer plates and pin shafts, wherein the inner plates are connected with the outer plates in sequence through the pin shafts, each pin shaft between each pair of outer plates is provided with a sleeve in a sleeved mode, the inner plates are connected with the sleeves in a sleeved mode, each sleeve between two inner plates is provided with a roller in a sleeved mode, and a plurality of pairs of the uniformly-spaced outer plates on the hollow pin shaft chain are replaced by hollow pin outer plates, each pair of hollow pin outer plates is connected with a hollow pin. Two ends of the hollow pin are provided with connection portions which are used for being fixedly connected with the hollow pin outer plates. The hollow pin shaft chain is reasonable and firm in structure, and has longer service life compared with a similar type chain.
Description
Technical field
The utility model belongs to technical field of transmission, is specifically related to a kind of hollow bearing pin chain.
Background technique
Along with the development of society and the progress of science and technology, the level of industrial automation is also increasingly high.Wherein the commercial production production line is the important component part of industrial automation, and the hollow bearing pin delivering chain is very important transmission part on the commercial production production line.The delivering chain of existing technology structurally comes with some shortcomings, and causes being easy to generate in the using process wearing and tearing, distortion, thereby influences the whole service life of chain.
Summary of the invention
The purpose of the utility model is: propose a kind of rational in infrastructurely, firmly, the hollow bearing pin chain of long service life is to overcome the deficiency that existing technology exists.
For realizing the purpose of the utility model; Adopt following technological scheme to be achieved: a kind of hollow bearing pin chain; Include interior sheet, outer plate and pivot pin, described in sheet be connected successively through pivot pin with outer plate, be with sleeve on the pivot pin between the every pair of outer plate; Sheet is enclosed within on the sleeve in described, is arranged with roller on the sleeve between the said two interior sheets; Many on the hollow bearing pin chain are substituted by the hollow pin outer plate equally spaced outer plate, are connected with hollow pin between every pair of hollow pin outer plate.
As preferred version: described hollow pin two ends are provided with the joint in order to be fixedly linked with the hollow pin outer plate.
Compared with prior art, the beneficial effect of the utility model is: because the hollow bearing pin chain structure of this model utility is reasonable, firmly, have longer working life than chain of the same type.
