As a new type of transmission device, the miniature ball screw has the advantages of high precision, high transmission efficiency, low noise and long life. It is widely used in various small mechanical equipment, especially in precision machinery, medical equipment, drones and other fields. The miniature ball screw is mainly composed of three parts: the screw body, bearing and nut.
The screw body is the core part of the miniature ball screw, usually made of high-precision alloy materials such as stainless steel, alloy steel, carbon steel, etc. The screw body is machined with a spiral groove for transmitting motion and power.
The bearing is an important supporting component of the miniature ball screw, which is used to ensure the stability and precision of the screw during movement. The bearing usually adopts ball bearings or roller bearings, which have the advantages of high precision, high rigidity and low friction.
The nut is another part of the miniature ball screw, which is usually used in conjunction with the screw body. The nut is machined with a spiral groove, which matches the spiral groove on the screw body to achieve the transmission of motion and power.
The working principle of the miniature ball screw is to use the ball rolling on the track to achieve the relative movement of the threaded shaft and the threaded sleeve. When the threaded shaft rotates, the ball is driven by the cage to roll on the track, thereby driving the threaded sleeve to move along the axial direction of the threaded shaft to achieve the purpose of transmission. This mode of movement can achieve precise linear motion and precise positioning. At the same time, due to the characteristics of high precision, high rigidity, and low friction of the micro screw, its motion accuracy and stability are guaranteed.
In addition, the micro screw can also adapt to different application requirements by changing the shape and size of the spiral groove. For example, some micro screws use trapezoidal spiral grooves, which can increase the bearing capacity and rigidity of the screw; while other micro ball screws use triangular spiral grooves, which can reduce friction and improve motion efficiency.
