Domestic linear guide - Class Double Arc

Products HTSD-LG series linear guides an overview of class double circular rail static stiffness and rigidity in the swing arc between the rails of both single and double arc, not only has high rigidity, but also has a high Self-calibration performance. Second, the raceway groove shape design HTSD-LG-type linear guides with a single arc raceway and sub-channel rail compared to the double arc (shown below), has a unique class of dual arc-shaped design. Deputy bear rails, when the light load in a single arc contact state, bear a heavy load when in double arc contact state, both the advantages of both, with good static stiffness, friction characteristics, preload, errors are capability and other performance indicators. Three characteristics ◇ 1, carrying capacity, stiffness in the spherical raceway rail, by forming grinding arc-shaped grooves, increasing the contact area, can withstand greater allowable load, to withstand impact loads and When heavy loads, bearing contact area is increased to improve the rigidity of the system. HTSD-LG-rail four-way deputy can withstand a variety of vertical and horizontal load, can be installed and designed for different purposes. ◇ 2, high precision work required, due to increase preload, make sure the ball does not slip, realize smooth movement, reduce impact and vibration motion, while deputy campaign rolling the ball rolling by means of linear guides implementation guide Deputy friction small, the difference between static and dynamic friction, easy to produce at low speed crawling. Repeat positioning accuracy, suitable for frequent start or change direction of moving parts. ◇ 3, sealing against dust and strong slider sealed at both ends with end caps, bottom sealed film, has a good dust properties. Meanwhile rail mounting hole with a screw cap to prevent dust accumulation plug, thus ensuring the life and adaptive performance. ◇ 4, easy to install thanks to precision processing technology, high pitch linear guide rail mounting holes of error is small, easy to install. Meanwhile HTSD-LG guideways Since slide built with steel cage, for easy removal. Our company can provide the assembly with "false guides" to the user. ◇ 5, interchangeability HTSD-LG deputy formal structure rail rule, easy to carry out high-precision measurements, increase the slider, change the slider to adjust the preload easily. Installation dimensions in line with national standards, in addition, HTPM company uses advanced processing techniques, deputy running rails, low noise, motion accuracy and reliability of the sport is well guaranteed. Fourth, the pre-load and rigidity HTPM designed guideways with dynamic load rating C of 7% for the pre-load limits. The following table lists HTPM-LG series of various pre-load value type products.

If you need detailed relationship between load and displacement of the slider, you can contact the company directly, HTPM company can provide detailed solutions for user selection. Fifth, the precision specifier HTSD rolling linear guide deputy accuracy standards and test methods according to People's Republic of China Machinery Industry Standard JB / T7175.4-2006 "Linear Rolling Guide Part 4: Acceptance technical conditions" to develop, with foreign companies in the same industry standards equivalent.
