This actuator consists of motor, reducer and drum;
1.1.2 Transmission characteristics
This gear transmission stability, high efficiency;
1.2 demonstration program
The prime design mover is the motor, after the coupling sleeve by the reducer drive to roll. Drive motor and reducer program uses a straight, simple structure, easy to manufacture.
High transmission efficiency of gear reducer, wide range of power and speed, long life, is the most widely used modern machines.
Overall, the transmission program meet the performance requirements of the working machine, to adapt working conditions, reliable work, in addition to simple structure, compact size, high transmission efficiency.
Part 2 Selection of Dynamo
2.1 Selection of dynamo
2.1.1 The total efficiency of the transmission device
η=η1η2η3
Portions of efficiency: even sleeve transmission efficiency η1=0.99, speed reducer efficiency η2=0.98, transmission efficiency is η3=0.98, substituted into the drum
η=0.99*0.98*0.98=0.95
Part 3 calculation and verification
3.1 rope diameter
According to customer specified wire diameter d = 14mmm;
3.2 drum diameter D
3.6 Conditions reel wall strength
3.6.1 stress
Source rope around the drum wall stress
