Ball screw machining, Shenzhen ball screw, Korea and Taiwan transmission machinery

 Ball features 1, compared with the sliding screw drive torque deputy 1/3 Because there are a lot of balls in the ball screw rolling movement between the screw shaft and screw nut, they are able to get a higher movement efficiency. Compared with the past sliding screw drive torque vice reach 1/3 or less, that the power required to achieve the same results as using the scroll motion screw vice 1/3. Helpful in saving. 2, high-precision ball screw is used to ensure that the manufacture of the world's highest levels of Japanese machinery and equipment consistent production out of the ball screw agents, especially in the grinding, assembly, inspection of the process plant environment ball screw supply of temperature and humidity were strictly controlled, because the sound quality management system so that accuracy can be fully guaranteed. 3, micro-feed may ball screw ball movement, so the starting torque is extremely small, sliding motion creeping phenomenon does not appear like that, to ensure accurate micro feed. 4, no backlash, high rigidity ball screw can be added to the pressure, the pressure due to the axial clearance can achieve negative, then get a higher rigidity (by giving the ball within a ball screw to increase pressure in actual use in mechanical devices, due to the ball repulsion can enhance the rigidity Ministry of wire mother). 5, the high feed may Ball movement due to the high efficiency, small heat, so I can realize high-speed feed (movement). Product structure innovation is to achieve high-speed ball screw foundation Pn and moderately increased the number of lead screw head is to achieve high-speed ball screw best choice. In the early 1989 completed a large lead ball screw "Seven? Five" key ball screw, helix angle for f> large lead ball screw 9 ° ~ 17 ° has been able to mass production. However, due to the genetic thread grinder Transmission Error "gene" and lead the greater accuracy more difficult to increase the lead. Therefore, taking into account the needs of accuracy, Pn lead to moderate increases, such as the nominal diameter and lead the match d0 × Pn to 40mm × 20mm, 50mm × 25mm, 50mm × 30mm and other appropriate line speed can reach 60m / min or more. The use of two-start thread is the number of turns in order to increase the effective bearing balls, thereby enhancing the screw vice rigidity and load carrying capacity, improved high-speed operation of the ball nut in smoothness. Although large lead ball screw (f> 17 °) can achieve higher line speed, but it is difficult to meet the accuracy and processing (minus) speed. Hollow strong cold. At high speed thermal deformation of the screw shaft is a source of processing errors. Meanwhile, in order to improve the system of rigid pre-stretch on the screw shaft will produce heat. Effective way to solve the problem is to heat the coolant through the interior of the hollow screw forced circulation cooling. Hollow screw ball screw shaft also helps to reduce inertia during high-speed operation to join, increasing torsional rigidity of the screw shaft. Beijing Machine Tool Research Institute in 1997 in cooperation with the Chengdu Tool Research Institute, completed large hollow ball screw hole machining and alloy steel precision deep hole from which to explore the process of experience could be applied in the production of high-speed ball screw.
