Selection of jack size No. 5 Check again with ball screw jack Type J-B. Yes. Set the hand wheel radius if the screw jack is to be used for manual operation. Yes. Yes. Specification Select temporarily the size No. of the screw jack having the standard capacity to meet the load. Assume the worm reduction ratio as"h"and obtain the required input shaft rpm from the lifting speed. Is the allowable maximum input shaft rpm exceeded? No. Calculate the required input shaft torque from the load at the time of lifting. Obtain the required power per jack from the required input shaft torque and rpm. Is the maximum power per jack exceeded? No. Is the allowable buckling load exceeded? No. If low speed or fine adjustment is specially required, check assuming the worm reduction ration as "L" If the jack is so designed that tensile loads are applied to the screw, the size No. can be selected economically without concern about bucking even when a long stroke is needed. Adopt the size No. Required jack performance <Step 1> Formula (1) Select temporarily J2G and obtain the input shaft min -1 n assuming the worm reduction ratio as H. V : lifting speed (mm/min) n : input shaft min -1 C : speed coefficient (see page 7) n Since the allowable input min -1 for J2G is 10 min -1, this n is acceptable. <Step 2> Next. obtain the required input shaft torque. Formula (2) Formula (3) [Calculation example] Load at the time of lifting: 30 kn Lifting speed: 0 mm/min. n T : required input shaft torquenm a : torque coefficient (see page 7) b : input shaft no load torque (see page 7) W : lifting load (kn) <Step 3> Obtain the required power from the values and P : required power kw n : input shaft min -1 T : required input shaft torque Nm Since the maximum power per jack for J2G is 2.3 kw from the table on page 7, the required power is not met. So the selection of J2G is inappropriate. Change the size No. to J3GH and perform the above calculatins again as follows. As the maximum power per jack for J3GH is 3.1 kw the required power is met. So this size No. shall be adopted. The following formula can also be used to obtain the required power. : jack efficiency

Overhang load = Input torque (N m) Radius of pulley, sprocket, etc. 3) In the presence of impact or Vibration, the self-locking function does not work in some cases. Then, the use of brake must be considered. 4) The service temperature ranges for standard products are -15 to + C for JOG to JGA and -15 to + C for J4A to J7A. If these ranges are exceeded, we can meet your requirements at your option. Please consult us. 5) As the lifting screw end is not locked, do not use the jack outside the service ranges. 6) Allowable loads of 2 kn and 4 kn are also available. Please refer to special bulletin (J-005). 7) If special accuracy, grade, etc., are necessary, please consult us.
