پیچ لید اسکرو T8 طول 30 سانتی متر همراه مهره برنجی

Description:
A leadscrew (or lead screw), also known as a power screw or translation screw, is a screw used as a linkage in a machine, to translate turning motion into linear motion. Because of the large area of sliding contact between their male and female members, screw threads have larger frictional energy losses compared to other linkages.
They are not typically used to carry high power, but more for intermittent use in low power actuator and positioner mechanisms.
The 8mm pitch offers a good trade-off between torque required to drive the screw and linear speed created. Each rotation of the lead screw will drive the mating nut precisely 8mm.
The OD of lead-screws is just under 8mm to ensure the proper fitment in an 8mm ID bearing or clamp.
These screws are commonly used in 3D printers, CNC routers, lift mechanisms, and automation projects.
Power screws are classified by the geometry of their thread. V-threads are less suitable for leadscrews than others such as Acme because they have more friction between the threads. Their threads are designed to induce this friction to keep the fastener from loosening. Leadscrews, on the other hand, are designed to minimize friction. Therefore, in most commercial and industrial use, V-threads are avoided for leadscrew use. Nevertheless, V-threads are sometimes successfully used as leadscrews, for example on microlathes and micromills.
Leadscrews are commonly used in linear actuators, machine slides (such as in machine tools), vises, presses, and jacks.
Leadscrews are manufactured in the same way as other thread forms (they may be rolled, cut, or ground).
