導軌絲桿用途，滾珠絲桿作為將旋轉運動轉化為直線運動或直線運動轉化為旋轉運動的理想產品，在設備中起著至關重要的作用，但在機器的設計過程中，我們要如何選擇滾珠絲桿呢？下面由涌創智深工程師金工為你介紹一下，以便在設計的過程中，省時又省力！從滾珠絲桿具有精度高、可逆性好、效率高等特點來定義絲桿

1. First of all, we need to know the ball screw washer type, screw thread type, tooth type axial clearance adjustment and pre-pressure to choose. In the selection process to do: economic and reliable, rigid high, easy to dismantle, so as not to be in use when in a hurry. As for the reason of choosing double nut Washer type preloading, it is because of its simple structure, good reliability, high rigidity and convenient disassembly.

2. There are two kinds of steel ball circulation in ball screw, inner circulation and outer circulation. The reason why we choose outer circulation is that its structure is simple, economical and practical.

Three. For the selection of thread raceway profile, we try to choose single ARC profile and double arc, which is mainly for debugging and stability. The reason for choosing 2 Double Arcs, however, is that the contact angle remains the same, and there is still a small gap at the intersection of the two arcs. According to the above points, we can confirm the choice of ball screw, however, in the actual machine design, we have to choose according to Type Selection Information!
