Japanese company THK solved the once difficult problem of rolling contact linear motion through its unique technological strength, and became the first company in the world to develop and commercialize linear motion (LM) guides in 1972. The use of linear motion systems can quickly improve the accuracy and speed of advanced electromechanical devices, and can save manpower investment. THK's LM rolling guide can enable ultra-high precision operation of machine tools and industrial automation machinery, and enable semiconductor manufacturing devices to operate within subminiature devices. Recently, the system has also been applied to LCD production lines, railway passenger cars, disabled assistance vehicles, medical equipment, skyscrapers and residences, as well as entertainment facilities. The range of use of LM rolling guide has exceeded all previous limitations.
The use of THK guide rails is not only reflected in the safety of high-speed rail, but also in the comfort performance of high-speed rail. Currently, this technology is used in the first class cabin of the Northeast Line, allowing passengers to enjoy safety and comfort while riding.
LM track width 30mm~60mm
● SPR/SPS 20LR ● SPR/SPS 25LR ● SPR/SPS 30LR ● SPR/SPS 35LR ● SPR/SPS 45LR
In order to surpass traditional LM guides and achieve ultra-low volatility and ultra-high rigidity, the following three points have been adopted:
① . 8 rolling channels
② Small diameter steel ball
③ Ultra long slider
As a result, not only does it significantly increase the effective number of steel balls, but it also suppresses the amplitude of the rolling element to the minimum. Achieved low volatility comparable to static pressure guidance systems. At the same time, the minimization of deformation of the steel ball achieves ultra-high rigidity over the roller guide rail. Contribute to the high-precision of the device.
After talking about high-speed rail, it's time to talk about shock absorption. Japan is an island country with frequent earthquakes, typhoons, and tsunamis, which have caused significant disasters and damage to daily life and production. In order to avoid greater losses, current houses use high-performance shock absorption structures. Among them, it is necessary to mention the design (solution) developed by THK company. In actual earthquakes, even if the buildings are not damaged, The personnel inside may also be injured in the second accident. Valuable property indoors may fall and be destroyed. In order to prevent such damage, the idea of indoor items being 'not subject to shaking' is crucial. There are two main types of seismic technology to protect life and property from the threat of earthquakes: "seismic resistance" and "seismic isolation". The former refers to strengthening columns, beams, and walls to resist earthquakes, while the latter refers to installing components on the foundation of a house that can absorb ground vibrations. If the house is directly located on its foundation, it means it is directly affected by the earthquake. The seismic isolation component is similar to a buffer pad and can provide seismic protection for the house. THK has fully utilized the knowledge and experience gained in seismic isolation technology in residential buildings, enabling the implementation of seismic isolation strategies for indoor items.
In 1971, THK was established in Meguro ku, Tokyo, initially named Toho Seiko Co., Ltd. The name "THK" represents "Toughness", "High Quality", and "Know how". In 1972, THK became the first company in the world to develop a method of achieving linear motion through rolling contact, and began manufacturing and selling a commercial achievement: linear motion (LM) guides. The goal is to promote social progress and industry development by following these three principles in the process of technology development and product manufacturing.
