你知道組裝滾珠絲桿有多少種不同的方法嗎?
Do you know how many different ways to assemble the ball screw?
一般情況下,THK滾珠絲杠可以通過以下方式組裝:
In general, THK ball screws can be assembled in the following ways:
(1)雙推,單行道
(1) Double push, one way
螺釘一端固定,一端自由。固定端軸承承受軸向力和徑向力。這種類型的支撐用于小沖程的短絲杠。
One end of the screw is fixed and the other end is free. The fixed end bearing bears axial force and radial force. This type of support is used for small stroke short lead screws.

(2)雙推一撐
(2) Double push and one support
絲杠一端固定,另一端支撐。固定端軸承承受軸向力和徑向力。支承端軸承僅能承受徑向力,并能使跟蹤軸向浮動,能避免或減少因自重和彎曲而產生的絲杠。同時,THK滾珠絲桿熱變形可自由延伸一端。
One end of the lead screw is fixed and the other end is supported. The fixed end bearing bears axial force and radial force. The bearing at the supporting end can only bear radial force and make the tracking axial floating, which can avoid or reduce the lead screw caused by self weight and bending. At the same time, THK ball screw thermal deformation can be freely extended to one end.
(3)雙推,雙推
(3) Double push
螺絲端固定。固定端軸承能同時承受軸向力和徑向力。該支護方法可在THK滾珠絲杠上施加適當的預緊力,提高絲杠的支護剛度,部分補償絲杠的熱變形。
Fix the screw end. Fixed end bearing can bear axial force and radial force at the same time. The support method can apply appropriate preload on THK ball screw, improve the support stiffness of the screw, and partially compensate the thermal deformation of the screw.
(4)采用螺釘固定和螺母旋轉驅動方式
(4) Screw fixation and nut rotation drive
此時,螺母旋轉,一邊移動一邊沿著固定導螺桿軸向:因為導螺桿不動,它可以避免臨界速度的限制,避免各種各樣的問題,當細長THK滾珠螺桿高速運行。螺母慣性小,運動靈活,轉速高。這樣可以對絲杠施加預緊力,提高絲杠的支撐剛度,補償絲杠的熱變形。
At this time, the nut rotates and moves along the axis of the fixed guide screw: because the guide screw does not move, it can avoid the limitation of critical speed and various problems. When the slender THK ball screw runs at high speed. The nut has small inertia, flexible movement and high rotation speed. In this way, the preload can be applied to the lead screw to improve the support stiffness of the lead screw and compensate the thermal deformation of the lead screw.
