Sizing of telescopic applications T elescopic s lides R ANGE The main factors for sizing the slides for a telescopic movement: - The weight/forces of mobile part and their position compared to slides. - Presence of dynamic forces / eventual abuse - Max. acceptable flexion - Max. acceptable extraction/closing force of mobile part - Ambients, frequency, speed - Expected lifetime All load capacities Co rad, are indicated per single slide and with the load perfectly centered. I.e an homogeneous load placed between 2 slides. Hereby the load P is acting as a radial point load, at half the extension and in the middle between the 2 slides. The load capacity for a pair is then : P = 2 • Co rad Co rad When sizing a telescopic application, it must be carefully evaluated if the load is centered. Also it must be considered if any external dynamic forces, or possible abuse could further increase the load forces acting on the slides. In case the load isn’t centered. i.e. load center Pe1 more towards one of the slides, and/or more towards the tip of the load, the center weighted load must be calculated for the must slides = Pe1 , to be inserted in formula on next page. Co rad = = Pe1 = (P • a) (a + b) • fp Where : P = Weight/load of mobile part a, b = distances from centered load to left/right slide fp = load position coefficient, based on relation of “c” distance between actual load P and load Co rad position, compared stroke H . The coefficient fp is obtained from below diagram. as the ratio between “c/H” . When only 1 slide the formula is Pe = P • fp P Pe2 a b Pe1 Capacity load reduction according to the position of the load P. P fp Stroke H c c/H = = 74
Verification of load capacity Mz Co rad To assure a correct selection of the slides according to the slide’s load capacity, it is assumed the known different forces acting on the slides, which then must be decomposed in : radial, axial or moment forces. Then again compared to load/moment capacities indicated for each single product in previous pages. For the slides with intermediate element TLS, TLR, TLA the verification is mainly down to comparing the load capacity Co Rad. to Pe as calculated on previous page, including a safety factor Z . Pe
