Nylon roller features:
1, galvanized roller has high wear resistance, low friction coefficient, not easy to wear belt;
2, the nylon roller has the self lubrication oil, not good, not easy to use in harsh conditions;
3, nylon roller has antistatic, anti ageing, smoldering, chemical (acid, alkali and organic solvent) corrosion;
4, can withstand repeated shocks, vibration;
5, nylon roller use ambient temperature range: - 40 C ~ 80 c;
6, excellent mechanical properties, light weight, easy installation, no maintenance;
7, nylon roller voice low (3-7DB) smooth operation, long life (is the metal roller life of 3-5 times).
Economic analysis of roller manufacturing
(1) investment equipment is the result of comprehensive balance of economy and technology, regardless of scale production and non scale production. Such as the investment of 300 thousand yuan of equipment, according to the cost of recycling equipment for 5 years, the annual production of 10 thousand sets, together with the cost of equipment maintenance, the production cost of at least $10 per set.
(2) it is an economic and technological comprehensive optimization of the production process of the roller production by using the method of non - Large - scale cast iron bearing seat. Cast iron bearing seat of the finished product is more than 9 tons of cold finished products bearing base of about $1, a set of roller bearings need only 2 seats, a total cost of about $18. But the iron bearing large interference pressing, can save cylinder stop processing costs 8 yuan, at least to save the bearing seat and the simplified welding manual and material costs 12 yuan, saving the cylinder material costs 10 yuan (not to be simplified because processing can properly reduce the wall thickness of 0.5 ~ 1.0mm), provincial special section amortization of equipment and maintenance costs about 10 yuan.
(3) a comprehensive comparison of the use of non - cast iron bearing seat of the greater pressure on the installation process, than the use of cold drawn bearing seat welding process, each roller manufacturing costs can be reduced by at least an average of about 20 yuan. According to an annual output of 10 thousand sets of calculations, the annual increase of more than 200 thousand yuan profit, great benefits.
The endless iron bearing large interference pressing roller manufacturing process, can give full play to the advantages of general transportation equipment, saving equipment investment and maintenance costs; roller manufacturing, the quality will be better, the cost will be lower, the efficiency will be higher. |
