The most important property of control cable is its ability to transmit force from the control mechanism to the actuator (in other case why do you need it?).<\/p>\n
But even ancient noticed that friction forces prevent any movement, especially when the route of laid control cable has a lot of bends.<\/p>\n
Known task: whether the ten-year child can hold sea ship with rope? It can if entwine rope around the post. Because as a result of \u201cn\u201d turns of rope force required for its retention is reduced to \u0422<\/strong>0<\/sub><\/strong>\/<\/strong>\u0422<\/strong> = e2<\/sup><\/strong>p<\/sup><\/strong>m<\/sup><\/strong>n<\/sup><\/strong> times. This is the famous Euler formula. If there are many bands of route, this is a major obstacle for force transmission of control cable.<\/p>\n And why there are engineers? As they compared the control cable with a linear bearing, so immediately realized: \u201csliding friction is less than rolling friction\u201d and they came up with the design of the FLEXBALL cable. If standard control cable or bowden can translate push-pull forces not bigger than 1000-2000 N. With bigger efforts will work control cables manufactured exclusively by special FLEXBALL technology (push-pull efforts from 800 to 15000 N). In this case cable efficiency close to 100% without loss of travel (backlash). To find needed cable, please see our catalog.<\/strong><\/p>\n All this is difficult, but it is achievable, Design of control cable by FLEXBALL technology is shown below:<\/p>\n Why such control cable maybe need?<\/p>\n FLEXBALL cables used in particularly important cases such as in aircraft, high-speed rail transport, trains and subway trains, in sports cars etc., wherever necessary precision transmission of large forces.<\/p>\n Please note that during transportation the cable should be placed in a certain way.<\/p>\n<\/p>\n
