With the continuous development of modern manufacturing technology, great changes have taken place in the traditional manufacturing industry. Numerical control technology, mechatronics and industrial robots have been more widely used in production. At the same time, the positioning accuracy, guiding accuracy and feed speed of the mechanical transmission mechanism are constantly improving, which has greatly changed the traditional guiding mechanism. It meets the requirements of today's machinery for high precision, high speed, energy saving and shortening the product development cycle. It has been widely used in various heavy combined machining machines, CNC machines, high-precision EDM cutting machines, grinders, industrial robots and even general industrial machinery.

1.適應(yīng)高速運動且大幅降低驅(qū)動功率

1. Adapt to high-speed movement and greatly reduce driving power

采用滾動直線導(dǎo)軌的機床由于摩擦阻力小，可使所需的動力源及動力傳遞機構(gòu)小型化，使驅(qū)動扭矩大大減少，使機床所需電力降低80%，效果明顯?？蓪崿F(xiàn)機床的高速運動，提高機床的工作效率20~30%。

Due to the small friction resistance of the machine tool with rolling linear guide, the required power source and power transmission mechanism can be miniaturized, the driving torque can be greatly reduced, the power required by the machine tool can be reduced by 80%, and the energy-saving effect is obvious. It can realize the high-speed movement of the machine tool and improve the working efficiency of the machine tool by 20 ~ 30%.

2.承載能力強

2. Strong bearing capacity

滾動直線導(dǎo)軌副具有較好的承載性能，可以承受不同方向的力和力矩載荷，如承受上下左右方向的力,以及顛簸力矩、搖動力矩和擺動力矩。因此，具有很好的載荷適應(yīng)性。在設(shè)計制造中加以適當(dāng)?shù)念A(yù)加載荷可以增加阻尼，以提高抗振性，同時可以高頻振動現(xiàn)象。而滑動導(dǎo)軌在平行接觸面方向可承受的側(cè)向負荷較小，易造成機床運行精度不良。

The rolling linear guide rail pair has good bearing performance and can bear force and torque loads in different directions, such as up, down, left and right, as well as bumping torque, shaking torque and swinging torque. Therefore, it has good load adaptability. Proper preloading in design and manufacture can increase damping, improve vibration resistance and eliminate high-frequency vibration. The sliding guide rail can bear less lateral load in the direction parallel to the contact surface, which is easy to cause poor operation accuracy of the machine tool.

3.組裝容易并具互換性

3. Easy assembly and interchangeability

傳統(tǒng)的滑動導(dǎo)軌必須對導(dǎo)軌面進行刮研，既費事又費時，且一旦機床精度不良，必須再刮研一次。滾動導(dǎo)軌具有互換性，只要更換滑塊或?qū)к壔蛘麄€滾動導(dǎo)軌副，機床即可重新獲得高精度。

The traditional sliding guide rail must scrape and grind the guide rail surface, which is both time-consuming and time-consuming. Once the accuracy of the machine tool is poor, it must be scraped and grinded again. The rolling guide rail is interchangeable. As long as the slider or guide rail or the whole rolling guide rail pair is replaced, the machine tool can regain high precision.

如前所述，由于滾珠在導(dǎo)軌與滑塊之間的相對運動為滾動，可減少摩擦損失。通常滾動摩擦系數(shù)為滑動摩擦系數(shù)的2%左右，因此采用滾動導(dǎo)軌的傳動機構(gòu)遠優(yōu)越于傳統(tǒng)滑動導(dǎo)軌。

As mentioned earlier, since the relative motion of the ball between the guide rail and the slider is rolling, the friction loss can be reduced. Generally, the rolling friction coefficient is about 2% of the sliding friction coefficient, so the transmission mechanism using rolling guide rail is far superior to the traditional sliding guide rail.
