Analysis of the operating environment of screw jacks
1. The maximum allowable power is a parameter under conditions of an ambient temperature of 20℃ and a duty cycle of 20% per hour. 2. The overall efficiency is a parameter under grease lubrication conditions. 3. The allowable torque, power, and speed vary when lifting different loads, and the maximum power varies with different duty cycles. 4. For jacks with double guide sleeves, the screw is allowed to withstand a certain amount of lateral force in addition to axial force. 5. The worm gear shaft extension is allowed to withstand a certain amount of radial force and is permitted to be fitted with gears, sprockets, or pulleys. 6. Worm gear screw jacks are generally self-locking when stationary.
