Characteristics of Changsha elevator models and screw specifications

Structural type of screw lift.
Elevators are divided into structural types.
The screw performs rotational movement and axial movement at the same time.
The screw makes a rotational motion, and the nut on the screw moves axially.
Assembly type of screw lift.
Each structural type of elevator is divided into two assembly types.
The screw (or nut) moves upward.
The screw (or nut) moves downward.
Screw head type of screw lift.
The structural type of the screw head of Changsha elevator is divided into.
Four types: Cylindrical type), (Flange type), (Threaded type), (Flat head type).
The structural type of screw head is divided into two types: (cylindrical type) and (threaded type).
The transmission ratio of the screw lift.
Pole lifts are divided into two transmission ratios, namely normal and slow speed.
Screw protection.
The protection of the elevator screw is divided into basic type, anti-rotation type and type with protective cover.
The protection of the elevator screw is divided into basic type and type with protective cover.
In screw lifts, the specification of the screw is one of the aspects. The trapezoidal screw is generally a trapezoidal thread. The specifications of the screw in screw lifts mainly include Hunan lifting platform, and.
There may be some differences among manufacturers with different screw models and specifications in screw lifts. This is mainly caused by different specifications and standards of screws in screw lifts.
What are the characteristics of the ball screw transmission mechanism? This is also a common question. The following is the answer for those who are proficient in mechanics.
Characteristics of the ball screw transmission mechanism.
Compared with the sliding Hunan elevator screw, the driving torque of the ball screw transmission mechanism is only one-third, and the movement efficiency is high and it can save electricity.
The transmission efficiency of the ball screw transmission mechanism can reach % to %, and it can convert torque into thrust, or convert thrust into torque, that is, convert between the two.
The friction is point contact rolling friction, so the friction resistance is very small, it has high sensitivity, and there is no low-speed crawling phenomenon, and it can control micro feed.
Mechanism During the transmission process of the Hunan elevator, the temperature rise is very small, so there is basically no primary elastic deformation phenomenon, and the screw rod can be pre-stretched to obtain high positioning accuracy.
The hardness of the balls and raceways can reach 100%, and good accuracy can be maintained. In terms of service life, it is also very good.
The lubrication of the ball screw transmission mechanism is also very convenient, and if the lubrication work is done well, its wear resistance and transmission efficiency can be improved, which is beneficial to the ball screw transmission mechanism.
