Description

Ball screw valve and assembling equipment thereof

Technical Field

The invention relates to the field of valves, in particular to a ball screw valve and assembling equipment thereof.

Background

The history of people using screws for transmission is not very long, and the traditional screws are always positioned badly and are easy to damage. Until 1898, the first attempt was to improve the poor positioning and damage of the screw by placing steel balls between the nut and the screw to replace sliding friction by rolling friction. In 1940, the ball screw was placed on the steering device of the car, and the ball screw was greatly revolutionized in its application, and gradually replaced the conventional ACME screw (ACME). Until recently, ball screws have become one of the most widely used components in the industry.

The ball screw is an ideal product for converting rotary motion into linear motion or converting linear motion into rotary motion. The ball screw is the most commonly used transmission element on tool machinery and precision machinery, and has the main function of converting rotary motion into linear motion or converting torque into axial repeated acting force, and has the characteristics of high precision, reversibility and high efficiency. Ball screws are widely used in various industrial equipments and precision instruments due to their small frictional resistance.

The ball screw consists of a screw rod, a nut, a steel ball, a preforming piece, a reverser and a dust remover. Its function is to convert the rotary motion into a linear motion, which is a further extension and development of the acme screw, the important meaning of this development is to change the bearing from sliding motion to rolling motion.

At present when valve heavy-calibre valve in market is bearing the high pressure, the switching torque of valve is very big, and along with the increase of reduction ratio, the valve bore is big more, and the number of turns of opening is just more, and the time of needs is just long, normally opens a heavy-calibre valve and need rotate the nearly 100 circles of hand wheel, and under the emergency, it is not only hard but also consuming time to close the valve, and the equipment of valve body and valve gap is usually by the manual work equipment screw and nut after punching, extravagant manpower, production efficiency are low.
