1 Please be sure to read a handling description before using it. Person who the work of transport, arrangement, plumbing/wiring, operation, maintenance/inspection had expert knowledge and skill. Please establish the safety device on your machine in the case that it is used for person's transportation. Please establish the safety device for fall prevention on your machine in the case that it is used to going up and down device. To the equipment which dislikes especially oil, please attach the damage prevention device such as the oil receiver for the oil leakage. Please do not approach or contact revolution parts during operation.

2 1. Compactibility and light weight 4. Availability of types The even distribution of the transmitted For the input stage, you can select from horsepower on 3 to 5 planetary gears bearing supported, motor direct coupling, substantially lessens each gear's load share. and bevel orthogonal thpes. For the output This load sharing concept enables the ultra portion, you can select from bearing compact and light gears. The 5-gear planetary supported, strengthened bearing supported, gears are produced with the Cantilever and built-in gear coupling types. Carrier, a Mitsui's original invension. 2. Fewer components Thanks to an ultrasimple structure (patented) and small number of components, Mitsui succeeded in producing extremely economical and easy to maintain gears Highly accurate roller bearing Minimum vibration and noise High efficiency 3. Shock load endurance It is very precisely produced by nitriding the internal gear and hardening both the inner central wheel and planet gears. Thus, it has the outstanding ability to withstand shock load.

Select the nearest reduction ratio from among the ratios of the Standard Reduction Ratio Chart (see Chart 1). Bear in mind the difference between the standard reduction ratio fo numbers under 315 and over 355. Reduction ratios not listed in Chart 1 require special design. it is recommended that ratios of Chart 1 are adhered to as much as possible. n Selecting the Number Te f1 f2 f3 f1 : Service factor based on load characteristics (see Chart 2) f2 : Service factor based on motor types (see Chart 3) f3 : Service factor based on starting frequency (see Chart 4) : Rated output torque of reduction gear (see Chart 7) Conditions of use 1 Electric motor N=37kW 2 medium load 3 no=1,500 min -1 4 no=18 min -1 5 Te=17640 N m 6 Tk=35280 N m 7 5 times/hour Reduction Ratio 83 hours 9 Pe=35kW 10ED=20% Le=5,000 hours 1,500 i = = (ip) 18 Deciding the Number Te f1 f2 f3 = = 23285N m From Chart 7, select the frame number so that will be over 23285N m 315 (Tn = 24210) Checking the Peak Torque 2 Tk Checking the Peak Torque N m O.K.
