How it works:Working principle : the planetary roller screw is a mechanical device to convert rotary motion to linear motion .Planetary roller screw drive mode is different, the main thread screw around planets arranged 6-12 threaded roller screw , so the rotary motion of the motor into linear motion of the screw or nut . Able to withstand heavy-duty planetary roller screw thousands of hours in extremely difficult conditions , so that makes it ideal for planetary roller screw requires continuous duty applications.Planetary roller screw and ball screw difference:Planetary roller screw and a ball screw similar structure , except that the load transmission element planetary roller screw threaded roller , is a typical line contact ; the load transmission element is a ball screw , a point contact .Carrying capacity and lifeAdvantage planetary roller screw and ball screw ball screw is able to provide higher rated dynamic and static load , thread roller ball will make alternative load quickly released through numerous line of contact , which can have a greater impact capacity.Planetary roller screw and a ball screw are applicable laws Hz HertzHertz Hertz pressure by the law, we can conclude : planetary roller screw can withstand static load of ball screw 3 times to 15 times the life of ball screw .Speed and accelerationPlanetary roller screw provides higher rotational speeds and higher acceleration , RGT and RGTB series planetary roller screw design agency in a non- circulating roller , and ball screw mechanism for the circulation of the ball , which will enable the rotational speed of the planetary roller screw is a screw of two times the acceleration will reach 3g.Lead and pitchPlanetary roller screw lead screw may be smaller than manufactured .Since the planetary roller and the pitch of the lead screw as a function of a lead may be less than 0.5mm or less. Planetary roller screw design calculations can lead to an integer or a decimal ( for example : every turn mobile 3.32mm), will not be required to reduction gear ratio . Change will not lead screw shaft and nut bring any change in the geometry .The lead screw and the ball diameter of the ball by the limit , and thus lead to a standard .Stiffness and StrengthNumber of the line of contact of the planetary roller screw will greatly increase the stiffness and impact resistance.
