Analysis of the use environment of the screw elevator

1. The maximum allowable power is a parameter under the condition that the ambient temperature is 20°C and the work duration is 20% per hour.
2. The total efficiency is a parameter under the condition of grease lubrication.
3. When lifting different loads, the allowable torque, power, and speed are different, and the maximum power for different starting continuity rates is different.
4. For elevators with double guide sleeves, the lead screw is allowed to bear a certain lateral force in addition to the axial force.
5. The worm shaft extension is allowed to bear a certain radial force, and it is allowed to install gears, sprockets or belt pulleys.
6. The worm gear screw elevator can generally be self-locking in a static state.
