Five things I should know about dryspin® lead screw technology: Importance of lead screw technology, details about the product range of dryspin® lead screw drives, difference in thread types, individual machining and configuration, and the lubrication of lead screw drives.
The thread is a profiled indentation that runs along a helical line wound around a cylinder. The type of lead screw is defined by the profile shape, the pitch, the number of threads and the direction of rotation. You will find more terms related to lead screws in another blog post. Basically, lead screw drives are machine elements that convert rotary movement into linear motion. In this blog post we look at one of the common thread sizes: the 10×3 thread size.
Our lead screw support blocks are available in thread sizes of 6 mm. Choice of mounting: plain bearings or, with higher dynamics, ball bearings (BB). All lead screw support blocks, like the matching lead screw clamp rings, are supplied in hard anodised aluminium.
How exactly is axial clearance defined? What must we watch out for? And what possibilities does igus offer for reducing axial clearance? The axial clearance is used to describe the lost motion, i.e. the “dead travel” on the lead screw, or in other words the gap between the lead screw and the lead screw nut.
What is the difference between left-hand and right-hand threads? How can I recognise the thread direction even without a test? The thread rotation direction right or left can be easily determined with a visual inspection. If you look at the lead screw from the front, you can best see the difference between left-hand and right-hand threads.
