Abstract
The utility model relates to an improved bush roller chain. In the present bush roller chain, two through holes are formed in two ends of the pin shaft connecting chain plates, and two rivets are provided for connecting the chain plates, therefore, the structure requires longer time for manufacturing technique, and increases the expense on labor and material. The improved bush roller chain includes multiple chain plates arranged in parallel, wherein corresponding chain plates are connected through pin shafts; the improved bush roller chain is characterized in that limit stops propped against the chain plates are formed at one ends of the pin shafts, and through holes are formed in the other ends thereof; rivets are assembled in the through holes; and stepped surfaces are formed on the pin shafts at positions close to the limit stops. According to the utility model, the limit stops are formed at one ends of the pin shafts, the through holes are formed in the other ends thereof, and the rivets are assembled in the through holes to connect the chain plates; therefore, the manufacture process of the pin shafts is simplified, the mounting and demounting of the products are facilitated, the expense for labor and material is lowered, and further the production cost of an enterprise is lowered.
Description
Technical field
The utility model relates to the driving component of FU series conveyor, especially a kind of improved sleeve-barrel roollr chain.
Background technique
Chain belongs to flexible traction organ, and drive scraper plate in service is walked together, is fed forward thereby promote material.Can produce polygon effect when chain and sprocket engagement, make chain speed inhomogeneous, move steadily inadequately, cause noise to increase, also can cause dynamic load, so motion speed should not be too fast.The delivering chain of FU series conveyor mainly contains 3 kinds: dropforged chain, bush roller chain and two plate chain, and wherein bush roller chain has rotation flexibly, long service life, supporting and guiding are easy to solve the lower advantage of noise during operation.Be applicable to MS, MC, MK, MX type buried plate conveyor.And the bearing pin that connects carrier bar in the bush roller chain has two through holes at two ends, and is equipped with 2 rivets and is used to connect carrier bar, and the required manufacturing process time of this structure is longer, has also increased manual work and Master Cost.
Summary of the invention
The utility model provides a kind of improved sleeve-barrel roollr chain to the problem that existing technology exists, and manufacturing and processing technology are simple, and assembling is reliable, reduces entreprise cost.
The utility model mainly is able to solve through following technical proposals: a kind of improved sleeve-barrel roollr chain; Comprise a plurality of carrier bars that laterally arrange; Link to each other through bearing pin between the corresponding carrier bar; It is characterized in that described bearing pin one end form with carrier bar against positive stop, the other end has through hole, dummy rivet in the through hole.
Next-door neighbour's positive stop place forms step surface on the described bearing pin.
The bearing pin of the utility model at one end forms positive stop, and the other end has through hole and disposes rivet to connect carrier bar.Simplify the manufacture process of bearing pin, also made things convenient for the installation and removal product, reduced manual work and Master Cost, further reduced the enterprise production cost.
Description of drawings
Fig. 1 is the structural representation of existing bearing pin
Fig. 2 is the pin shaft structure schematic representation of the utility model
Fig. 3 is the structural representation of the utility model.
Embodiment
Pass through embodiment below, and combine accompanying drawing, do further bright specifically the technological scheme of the utility model.
A kind of improved sleeve-barrel roollr chain shown in Fig. 2 and 3; Comprise a plurality of carrier bars that laterally arrange 5, link to each other bearing pin 1 outside installing sleeve 6 through bearing pin 1 between the corresponding carrier bar 5; Bearing pin 1 one ends form with carrier bar 5 against positive stop 3; The other end has through hole 2, dummy rivet 7 in the through hole, and next-door neighbour's positive stop 3 places also form step surface 4 on the bearing pin 1.
The bearing pin of the utility model at one end forms positive stop, and the other end has through hole and disposes rivet to connect carrier bar.Simplify the manufacture process of bearing pin, also made things convenient for the installation and removal product, reduced manual work and Master Cost, further reduced the enterprise production cost.
At last, should be pointed out that above embodiment only is the more representational example of the utility model.Obviously, the utility model is not limited to the foregoing description, and many distortion can also be arranged.Every technical spirit according to the utility model is to any simple modification, equivalent variations and modification that above embodiment did, all should think the protection domain that belongs to the utility model.
Claims (2)
