Why the speed in the linkage system of a worm gear lead screw jack cannot be too fast？There are some reasons that should be considered:
1. Safety Considerations
The screw jack handles heavy loads, and excessive speed may cause loss of control of the equipment or load, increasing the risk of accidents—especially during stopping or emergency braking when large inertial forces occur.
2. Mechanical Structure Limitations
The worm gear screw jack actuator mainly uses worm gear transmission, which has a strong self-locking feature but relatively low efficiency. Excessive speed can cause excessive wear or damage to the worm gear teeth and lead screw surface.
3. Heat Generation and Dissipation Issues
High-speed operation increases friction and generates a lot of heat. The worm gear screw lifter assembly has limited heat dissipation capability, which can lead to lubricant failure and overheating of components, shortening equipment lifespan.
4. Reduced Positioning Accuracy
Machine screw jack actuator are often used where precise positioning is required. Too high speed can cause instability or vibration, adversely affecting work precision and product quality.
5. Limitations of the Drive Motor and Control System
Excessive speed may exceed the design parameters of the motor and control system, causing overloads, frequent protective shutdowns, or control malfunctions.
Therefore, to ensure safe operation, extend service life, and maintain positioning accuracy, the speed of the linkage system in worm gear lead screw lifters is usually designed to be low and stable.
