Calculation of flexion T elescopic s lides R ANGE K P = = Co rad The extended slides have a minor flexion “ f ” in function of applied load P and its own construction. What gives the strength of the slides, are merely the intermediate element’s shape. The slides with a long S-shape intermediate element TLS, TLR, TLA allow for much lower flexion, than the compact slides TSQ, TLQ, TQA, even though all base components are identical. L (mm) The flexion can be estimated as approximately: f = (K • P) 1000 K Where: K = coefficient obtained from graph, in function of slide type and length. P = applied load in the central point of the single slides ATTENTION: The flexion “ f “ is a conceptual flexion. The actual flexion is strongly influenced by the structural rigidity and assembly precision. Co rad In case the load P was applied on two slides in an eccentric position, it is necessary to determine the equivalent component Pe for each slides (see page 74) and replace it to P in the formula. L (mm) Extension & closing forces The required force Fe to extend the applied load, is determined by the friction of the slide’s rolling components and applied load Pe is: Fe ≈ 0,01 • P (N) P Fc The required force Fc to close the applied load is Fc = 0,01 • P + f • P (N) H Fe Where : P = radial load applied on single rail f = calculated flexion H = stroke of slide For applications with 2 slides, with even load the force is x 2 . In addition there might be some additional “binding friction” from non precise assembly. For applications requiring lowest extension/closing forces is recommended roller slides series TLR and TLQ . 76
Speed limitation The speed of the slides is limited by strength of the stoppers , which move the intermediate element along with each opening/closing of the slides. The critical point is the impact, when stopper in rail hits the stopper in intermediate element. The stoppers are different among types of slides, but the same for all lengths of same slide. As the impact force, increase with the lenght og slides, based of same speed, as the weight of intermdiate element increases propotional with the increased lengths, the max impact the stoppers can absorb is: Ek = m • v Where: m = weight of element v = Speed of slide Hereby short slides can operate at faster speeds than long slides. The roller telescopic slides TLR, TLQ , TLA and TQA have strong impact stoppers, to provide the highest speed. The speed range is from 1m/s for the shorter slides to 0,2m for the longest slides. Besides higest speed, the roller telescopic slides are also the most silent and smooth moving slides due to the roller. The strong ball-cage slides TLS offer a speed range of 0,8m/s for shorter slides to 0,2m/s for the longest slides. The TSQ and SR slides are without any rubber inserts, just square pins, so metal against metal impact. The speed range is hereby lower; 0,6m/s for shorter slides to 0,1m/s for max. lengths. Speed (m/s) Lenght (mm) Materials and treatments The rails, except TLAZ-TLAX-TQAZ-TQAX slides are hardened steel profiles with T RACE NOX treatment, to provide a hardened surface, min 58HRC on all surfaces, an overall high corrosion resistance of the entire profile. The treatment provides unique long lasting telescopic slides, even for severe high frequency application and corrosive ambients. The T RACE NOX treatment is made in 3 steps : 1) High-depth nitriding hardening 2) Black oxidation 3) Impregnation in protective black mineral oil The T RACE NOX treatment is done on the complete profile, leaving the rail a smooth matt black finish.
