The screw lifter is a kind of lifting equipment with relatively complex and reasonable internal structure. The internal structure is worm gear. When the worm is rotated, the worm drives the worm gear, and the worm gear drives the screw rod or the nut on the screw rod to do linear lifting. The internal structure of the rack elevator is relatively simple, and the rack is directly driven by the gear to do linear movement. Although the lifting speed is faster, it has many disadvantages in use and the price is relatively low.
The rack elevator appeared relatively early in China, and was gradually replaced by the elevator with worm gear and worm structure introduced from abroad.
The lead screw elevator operates more smoothly and safely, has strong bearing capacity, and is simple and diversified in installation. It can be used in conjunction with steering gear connecting rod and other accessories. It is suitable for all kinds of automatic equipment to assist manual or mechanical precision linear displacement. It can also be used with servo motor for precise positioning. The bearing capacity ranges from several hundred kilograms to more than one hundred tons, and can be used horizontally, vertically or even overturned.
The selection of the screw lift should pay attention to the following points: 1. It can not be used with overload or temporary load, which will have a certain impact on the service life of the machine; 2. It is not allowed to blindly select the model according to the base number, and it is necessary to calculate the limit load under the length of the screw lift; 3. It is necessary to calculate whether the power exceeds the allowable value during high-speed operation.
The screw lift is a foolproof equipment that does not need frequent maintenance. It has obvious advantages over other lifting equipment and is affordable. You need this part for your mechanical equipment as an assistant. You can communicate details with us.
