导轨丝杆用途，滚珠丝杆作为将旋转运动转化为直线运动或直线运动转化为旋转运动的理想产品，在设备中起着关重要的作用，但在机器的设计过程中，我们要如何选择滚珠丝杆呢？下面由涌创智深工程师金工为你介绍一下，以便在设计的过程中，省时又省力！从滚珠丝杆具有精度高、可逆性好、效率高等特点来定义丝杆

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!
