Abstract
The utility model discloses a faller chain for a stentering dryer. The faller chain comprises a plurality of chain blocks in the same structure and a plurality of hinge pins for connecting the chain blocks, wherein one ends of the chain blocks are integrally provided with male connecting portions, the other ends of the chain blocks are integrally provided with female connecting portions which are in inserting fit with the male connecting portions, the male connecting portions are provided with first pin holes, the female connecting portions are provided with second pin holes corresponding to positions of the first pin holes, and the hinge pins penetrate through the first pin holes and the second pin holes and are fixedly connected with the female connecting portions. The faller chain is characterized in that oil bearings are arranged in the first pin holes, the outer walls of the oil bearings are in close fit with the walls of the first pin holes, the hinge pins penetrate through the oil bearings, gaps are arranged between the hinge pins and the inner walls of the oil bearings, and the oil bearings are made of powder metallurgy. The faller chain has the advantages that during usage, relative rotation occur between the oil bearings and the hinge pins, the oil bearings are abraded, only the oil bearings are needed to be replaced after abrasion, and therefore production and maintenance costs are reduced substantially.
Description
Technical field
The utility model relates to a kind of chain, especially relates to a kind of tentering dryer needle plate chain.
Background technology
Existing tentering dryer is formed by connecting by the identical chain piece of a plurality of structures with the needle plate chain, the chain piece comprises the public link in tape spool hole and female link in tape spool hole, public link is connected by bearing pin with female link grafting back, bearing pin and female link rivet clasp can relatively rotate between bearing pin and the public link.The tentering dryer in use, because chain often bears bigger pulling force, time has been grown and will wear and tear, make that the axis hole of the public link of chain piece is widened, use is used less than just continuing in 2 years, and can't repair and need all to change, and the chain piece on tentering dryer can reach several thousand, all change the expense that needs hundreds of thousands unit, this has increased very high production cost to enterprise.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of the use and need not the tentering dryer needle plate chains all changed after the wearing and tearing, and it can reduce production, maintenance cost significantly.
The utility model solves the problems of the technologies described above the technical scheme that adopts: a kind of tentering dryer needle plate chain, comprise chain piece and the many bearing pins that are used for the connection of chain interblock that a plurality of structures are identical, one end of described chain piece has been wholely set public connecting portion, the other end of described chain piece is wholely set female connecting portion of pegging graft and cooperating with described public connecting portion, offer first axis hole on the described public connecting portion, offer second axis hole corresponding with the described first axis hole position on described female connecting portion, described bearing pin passes described first axis hole and described second axis hole, described bearing pin is fixedlyed connected with described female connecting portion, be provided with oiliness bearing in described first axis hole, the hole wall tight fit of the outer wall of described oiliness bearing and described first axis hole, described bearing pin passes described oiliness bearing, be provided with the gap between the inwall of described bearing pin and described oiliness bearing, the material of described oiliness bearing is powder metallurgy.
Offer first oil through on the described public connecting portion, offer second oil through corresponding with the described first oil through position on the described oiliness bearing, first oil through and second oil through are offered after oiliness bearing is assembled to first axis hole, be convenient to production and processing, described first oil through, described second oil through and described gap three are connected, be used for refueling the rate of wear of the chain that is conducive to slow down to chain.
The height of described oiliness bearing equates with the height of described public connecting portion, is convenient to assembling and changes.
Compared with prior art, advantage of the present utility model is owing to be provided with oiliness bearing in first axis hole, the hole wall tight fit of the outer wall of oiliness bearing and first axis hole, bearing pin passes oiliness bearing, be provided with the gap between the inwall of bearing pin and oiliness bearing, relatively rotate between oiliness bearing and the bearing pin in the use, the part that wearing and tearing take place is oiliness bearing, avoided to repair the problems that need whole replacings after the wearing and tearing of chain piece, the wearing and tearing back only needs to change oiliness bearing and gets final product, the chain piece then need not to change and can repeatedly reuse, and has reduced production significantly, maintenance cost; The material of oiliness bearing is powder metallurgy, and ABRASION RESISTANCE is better, has further reduced cost.
