Abstract
The invention discloses a kind of tenter dryer needle plate chain, comprise the identical chain block of multiple structure and the many bearing pins connected for chain interblock, one end of chain block has been wholely set public connecting portion, the other end of chain block is wholely set the female connecting portion coordinated with male connecting portion grafting, public connecting portion offers the first axis hole, female connecting portion offers second axis hole corresponding with the first axis hole position, bearing pin is through the first axis hole and the second axis hole, bearing pin is fixedly connected with female connecting portion, feature is provided with oiliness bearing in the first axis hole, the outer wall of oiliness bearing and the hole wall tight fit of the first axis hole, bearing pin is through oiliness bearing, gap is provided with between bearing pin and the inwall of oiliness bearing, the material of oiliness bearing is powder metallurgy, advantage relatively rotates between oiliness bearing and bearing pin in use procedure, and the part that wearing and tearing occur is oiliness bearing, only need change oiliness bearing, reduce production, maintenance cost significantly after wearing and tearing.
Description
Technical field
The present invention relates to a kind of chain, especially relate to a kind of tenter dryer needle plate chain.
Background technology
Existing tenter dryer needle plate chain is formed by connecting by the chain block that multiple structure is identical, chain block comprises the male link of band axis hole and female link of band axis hole, pinned connection is passed through after male link and female link grafting, bearing pin and female link rivet clasp, can relatively rotate between bearing pin and public link.Tenter dryer in use, because chain often bears larger pulling force, time has been grown and will wear and tear, the axis hole of the public link of chain block is widened, use and just cannot continue to use less than 2 years, and needs all replacings cannot be repaired, and the chain block on a tenter dryer can reach several thousand pieces, whole replacing needs the expense of hundreds of thousands unit, and this adds very high production cost to enterprise.
Summary of the invention
Technical problem to be solved by this invention be to provide a kind of use wearing and tearing after tenter dryer needle plate chain without the need to all changing, it can reduce production, maintenance cost significantly.
The present invention solves the problems of the technologies described above adopted technical scheme: a kind of tenter dryer needle plate chain, comprise the identical chain block of multiple structure and the many bearing pins connected for chain interblock, one end of described chain block has been wholely set public connecting portion, the other end of described chain block is wholely set the female connecting portion coordinated with described male connecting portion grafting, described public connecting portion offers the first axis hole, described female connecting portion offers second axis hole corresponding with the first described axis hole position, described bearing pin is through the first described axis hole and the second described axis hole, described bearing pin is fixedly connected with described female connecting portion, oiliness bearing is provided with in the first described axis hole, the outer wall of described oiliness bearing and the hole wall tight fit of the first described axis hole, described bearing pin is through described oiliness bearing, gap is provided with between the inwall of described bearing pin and described oiliness bearing, the material of described oiliness bearing is powder metallurgy.
Described public connecting portion offers the first oil through, described oiliness bearing offers second oil through corresponding with the first described oil through position, first oil through and the second oil through are offered after oiliness bearing is assembled to the first axis hole, be convenient to production and processing, the first described oil through, the second described oil through and described gap three are connected, for refueling to chain, the rate of wear of the chain that is conducive to slowing down.
The height of described oiliness bearing is equal with the height of described public connecting portion, is convenient to assembling and changes.
Compared with prior art, the invention has the advantages that owing to being provided with oiliness bearing in the first axis hole, the outer wall of oiliness bearing and the hole wall tight fit of the first axis hole, bearing pin is through oiliness bearing, gap is provided with between bearing pin and the inwall of oiliness bearing, relatively rotate between oiliness bearing and bearing pin in use procedure, the part that wearing and tearing occur is oiliness bearing, the problem needing all to change cannot be repaired after avoiding the wearing and tearing of chain block, only oiliness bearing need be changed after wearing and tearing, chain block then can repeatedly reuse without the need to changing, reduce production significantly, maintenance cost, the material of oiliness bearing is powder metallurgy, and ABRASION RESISTANCE is better, reduce further cost.
Accompanying drawing explanation
Fig. 1 is structure partial sectional view of the present invention;
Fig. 2 is structure partial top view of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, the present invention is described in further detail.
As shown in the figure, a kind of tenter dryer needle plate chain, comprise the identical chain block 1 of multiple structure and the bearing pin 2 of Duo Gen for connecting between chain block 1, one end of chain block 1 has been wholely set public connecting portion 3, the other end of chain block 1 is wholely set the female connecting portion 4 coordinated with the grafting of male connecting portion 3, public connecting portion 3 offers the first axis hole 31, female connecting portion 4 offers second axis hole 41 corresponding with the first axis hole 31 position, bearing pin 2 is through the first axis hole 31 and the second axis hole 41, bearing pin 2 is fixedly connected with female connecting portion 4, oiliness bearing 5 is provided with in first axis hole 31, the outer wall of oiliness bearing 5 and the hole wall tight fit of the first axis hole 31, bearing pin 2 is through oiliness bearing 5, gap 6 is provided with between the inwall of bearing pin 2 and oiliness bearing 5, the material of oiliness bearing 5 is powder metallurgy, public connecting portion 3 offers the first oil through 32, oiliness bearing 5 offers second oil through 51 corresponding with the first oil through 32 position, first oil through 32, second oil through 51 and gap 6 three are connected, the height of oiliness bearing 5 is equal with the height of public connecting portion 3.
Claims (2)
