screw lift is a kind of basic lifting part, has become an indispensable part of modern mechanical equipment, widely used in dry machinery, metallurgy, construction and other industries. Chemical, medical, cultural and health industries. It can accurately control and adjust the height of lifting or propulsion according to certain procedures. It can be driven directly by motor or additional power or manually. This is a one man lifts.
What are the advantages of the screw hoist?
1. Superior transmission efficiency
ball screw transmission system can get a lot of thrust with a slight torque, its transmission efficiency is up to 90%~98%, so it can also be converted from linear motion to rotary motion, which is more than 2 times the traditional sliding screw system.
2, high durability
Rolling steel ball has a long service life and precision retention, contact part after hardening and precision grinding, the process of circulation system is pure rolling, relatively tiny wear.
3, high precision
In the process of movement, the temperature rise of the screw lift drive system is tiny, which can obtain high positioning accuracy and repeated positioning accuracy, and can brighten to eliminate the axial clearance and prestretch the wire to compensate for thermal elongation.
4, smooth movement
The Ball screw transmission system is point contact rolling movement, extreme sensitivity during operation, no flutter when starting, no crawling phenomenon at low speed, tiny friction resistance, so it can accurately control trace feed.
5. Perfect synchronization
Because of the characteristics of no blocking, smooth movement, sensitive response, no skid, using multiple groups of the same ball screw transmission system to drive the same parts or devices at the same time, can get a excellent synchronization effect.
