Japanese THK ball screw manufacturers explain the ball screw circulation method

THK Ball Screw Manufacturer: Two Common Circulation Methods of Ball Screws When using ball screws, there are situations where the ball screw is separated from use or remains in contact with use. These two situations are divided into two circulation methods, namely the commonly known internal circulation and external circulation. In fact, internal circulation means that the ball is always in contact with the screw, while external circulation means that the ball is out of contact with the screw. Below is a brief introduction to the two circulation methods of ball screws. 1. Internal Circulation If it is an inner ring, it is mainly realized through an inverter. Inverters are actually of two types, one is a cylindrical cam inverter and the other is a flat oval inlaid block directional indicator. Compared with these two types of inverters, the latter is smaller, but the applicable environment requires higher precision, mainly for higher requirements on the size of the outer profile of the inverter and the groove on the nut. 2. External Circulation At the end of the ball circulation process, it returns to the ball screw nut through the spiral groove of the nut or sleeve for circulation. This circulation mainly includes the end cap, sleeve and spiral groove. Among them, the sleeve technology is better, but the tube protrudes from the nut body, so the size is relatively large. This external circulation structure has a much simpler manufacturing process and is widely used. The circulation methods of ball screws are mainly internal and external circulation. When choosing, it mainly depends on the requirements of the use environment and the use situation in each type of occasion. The external circulation type has low cost, but the gap of the raceway is not smooth enough, and it still has a certain impact on the smooth performance of the ball raceway. THK Ball Screw Manufacturer: The Main Working Principle of Ball Screws Ball screw transmission has high efficiency and accurate positioning. It is a widely welcomed and favored transmission component in current industrial machinery production. As we all know, it mainly converts linear motion into rotary motion or rotary motion into linear motion, and the switching between the two is relatively safe and convenient. The main principle of ball screw is to improve transmission efficiency and make positioning more accurate. The principle is described in detail below. First, the original trapezoidal screw, which is also known as a screw, has been basically replaced by a ball screw. The main reason is that the principle of the ball screw is that when rotary motion is converted into linear motion or linear motion is converted into rotary motion, as a transmission component, it can both improve transmission efficiency and accurately position. Second, the corresponding linear motion can be quickly realized. For example, when the ball screw is used as the driving body, the nut can realize the conversion of corresponding specifications following the rotation angle of the screw. That is to say, in this case, the passive workpiece can be connected with the nut seat or nut, so as to realize the corresponding linear motion work. In the final analysis, the main principle of the ball screw is that it can quickly convert rotary motion into linear motion, and the switching between these two motions is relatively easy. And it can ensure accurate positioning in the case of switching between the two. As a transmission component, the ball screw has excellent efficiency and accuracy, and can be used in many situations. That's all for the introduction of THK ball screw manufacturer today. Thank you for watching.

Original imported THK guide rail slider from Japan, SHS55LC+1020L, large quantity in stock, spot supply

Original THK guide rail slide, SHS55LC+1020L, imported from Japan. Large quantities in stock, available now. — Retainer-type roller guide rail Utilizing a roller retainer, this achieves ultra-high rigidity with low friction, smooth movement, and long-term maintenance-free operation. SHS-type ball retainer LM guide rail, world standard type Structure and features: Steel balls roll along four precisely ground rolling surfaces on the LM rail and LM slide. Through the ball retainer and the ball returner assembled on the LM slide, the steel ball rows perform a circulating motion. To ensure that the four directions of action on the LM slide have the same rated load, each steel ball row is designed with a contact angle of 45°. Therefore, it can be used in any posture, and because uniform pre-load can be applied, a low friction coefficient is maintained while strengthening the rigidity in four directions. At the same time, due to the low cross-sectional height and the high-rigidity design of the LM slide, stable high-precision linear motion can be obtained. The flange of the THK guide rail SHS-C type LM slide is threaded. It can be installed from either the top or bottom. It can be used in situations where through-holes for mounting bolts cannot be drilled on the worktable.

HTPM Kate Precision Machinery LM/LMW series miniature linear guide unit

Structural Features 1.Adopts a compact design with one roller track on each side, resulting in small size and light weight, making it particularly suitable for miniature equipment. 2.The groove design is a Gothic structure, with a contact angle of 45 degrees in all directions. Therefore, it has equal rigidity and load capacity in all four directions (up, down, left, and right). 3.Due to its wide guide rail width, the LMW series has high rigidity and high load capacity in terms of lateral torque, making it suitable for single use. LM7 and LM9 models also have the following features: 1.Part of the slider body uses resin material, which reduces the weight by 25% compared to ordinary sliders and reduces inertia. 2.The slider components are interlocked, resulting in a tighter structure and smoother ball circulation. 3.It has a retaining wire to prevent ball dropping. Even if the slider is removed from the rail, the balls will not fall off. 4.The guide rail, slider, steel balls, and retaining wire can all be made of stainless steel for good corrosion resistance.
