Engineering Enclosed Plastic Roller Drag Cable Chain
Basic parameters of drag chains
1.Material:reinforced nylon. It can stand with high pressure and has good tensile strength,toughness and elasticity ,wearing and falmable resisance.
2.Resistances:It is oil and acceleration is 5m/sec.(specfic speed and acceleration depends on specific).
3.Service life:Under normal conmal condition,5 million reciprocating motions can be reached(which is also related to the operating conditions.)
|Impact strength||50Kj/m2||Water Absorption||4%|
|Tenprature range||-40.C-130.C||Friction factor||0.3|
|Surface resistaned||1010-1012||Falme resistance||HB(UL49)|
Characteristics and Applications of Drag chains
1.The product can be used for such locations where repciprocating motions are required so that internally installed cables.oil pipes,gastubes and water tubes can be draged and protected.
2.Each joint of the chain can be opened up so as to facilitate repairs and maintenance.It can also be operated under high speed.
3.The drag chains have already extensively used in digital-controlled machine tools.electronic equipment,machinery for stone windows.moulding injectors,manipulators,lifting and transport equipment and automatic warehouses,etc.
Construction of the drag chains:
1.The appearance of the chain looks like the crawler of a tank consisting of certain number of joints ,The joints of crawler are freely turned round.
2.The same series of chain hsa same inner height and out height and same pitch but the inner herght radius R can be made per different specifications.
3.A unti chain joint is consisting of a left-right chain plate and updown cover.Each chain joint can be piened up so as to facilitate assembly and dismantal without threading.Cables,oil pipes and gaspipes can be put into the drag chain after the cover plate is opened.
4.Spacers are available for use,which are able to divide the space inside the chain into divisions according to requirements.
Installation for cable frag chains:
1.Put a screw driver vertically into the opening hole at both ends of the cover and then open the cover .Put the drag chain for cables and oip pipes according to the instructions provided .Put the cover back.Note that the fixed end and the moving end of a cable should be fixed by using a tension device
2.When used in a long sliding service,it is recommended to use a guiding grove,Please ask our technical personnel about the usage of the guiding grove.
