直線導軌滑塊有什么特點

來源:http://www.phkcgc.live/ 日期:2019-05-14 發布人:admin

  1)定位精度高

  1) High positioning accuracy
  使用直線導軌作為導向時,由于直線導軌的摩擦方式為滾動摩擦,不但摩擦系數降低至滑動導軌的1/50,動摩擦力與靜摩擦力的差距也變的很小。因此當負載平臺運動時,不會有打滑的現象發生,可達到很高的定位精度2)減少磨損能長時間維持高精度When using linear guideway as guide, because the friction mode of linear guideway is rolling friction, not only the friction coefficient decreases to 1/50 of sliding guideway, but also the difference between dynamic friction and static friction becomes very small. Therefore, when the load platform moves, there will be no slippage, which can achieve high positioning accuracy 2) Reducing wear and maintaining high accuracy for a long time.
  傳統的滑動導軌,無可避免的會因為油膜逆流作用造成平臺運動不良,且因運動時潤滑不充分,導致運行軌道接觸面的磨損,從而影響精度。而滾動導軌的磨損非常的小,所以設備能夠長時間的維持高精度。
  Traditional sliding guideways inevitably cause poor motion of the platform due to oil film countercurrent effect, and inadequate lubrication during movement, resulting in wear and tear of the contact surface of the running track, thus affecting the accuracy. The wear of rolling guide is very small, so the equipment can maintain high precision for a long time.
  3)適用高速運動且大幅降低設備所需驅動動力由于直線導軌移動時的摩擦力非常小,只需要較小的力便能讓負載平臺運動,尤其是在設備工作方式為經常性往復運動時,更能明顯的降低設備電力損耗。且因其摩擦產生的熱量較小,可適用于高速運動。
  3) It is suitable for high-speed movement and greatly reduces the driving power required by the equipment. Because the friction force is very small when the linear guideway moves, only a small force is needed to enable the load platform to move, especially when the equipment works in a regular reciprocating motion mode, it can significantly reduce the power loss of the equipment. Because the heat generated by friction is small, it can be applied to high-speed motion.
  4)組裝容易并具備互換性
  4) Easy assembly and interchangeability

  組裝時只需要銑削或者研磨機床上導軌裝配面,并按步驟將導軌和滑塊分別以特定扭力固定在機床上,即能夠重現加工時的高精度。滑動導軌的則很花費時間,且當導軌精度不良時又需要從新產花。直線導軌具有互換性,可分別更換導軌或者滑塊甚至直線導軌組,設備即可從新獲得高精密度的導向。
  When assembling, only need to milling or grinding the assembly surface of the guide rail on the machine tool, and fix the guide rail and slider on the machine tool with specific torsion step by step, which can reproduce the high accuracy of processing. Sliding guides take a lot of time, and when the accuracy of the guides is poor, they need to produce new flowers. Linear guides have interchangeability. They can be replaced by sliders or even linear guides. The equipment can obtain high precision guidance from the new.
  5)潤滑構造簡單
  5) Simple lubrication structure
  滑動直線導軌使用潤滑不足,將會造成接觸面金屬直接摩擦損毀機床,而滑動導軌潤滑充足并不容易,需要在機床適當的位置鉆孔供油。直線導軌則已經在滑塊上裝配油嘴,可直接以注油器打入油脂,也可換上專用油管接頭連接供油管,以自動供油機潤滑。
  Insufficient lubrication of sliding linear guides will cause direct friction damage to the machine tool, while sufficient lubrication of sliding linear guides is not easy, and oil supply needs to be drilled in the appropriate position of the machine tool. Linear guides have been fitted with oil nozzles on the slider, which can be directly injected into grease by the injector, or can be replaced with special tubing joints to connect the oil supply pipe for automatic lubrication of the oil supply machine.
