Transmission Screw thread types
| Thread Types | Features |
| Trapezoidal thread | T ISO Trapezoldal Thread:For transmission and posltion adjustment, wldely used In the mechanical Industry. |
| Metric thread | M ISO Metric Thread (60° ):The most common form of thread used for fastening and precislon transmission. |
| ACME thread | English threads can also be used for fastening connectlons,but not for high accuracy |
| Round thread | Wlth the same arc thread as ball screw, the transmission is smoother. |
| Goethe thread | Gothic double arc thread,drawing the advantages of ball screw, is the new products. |
| Reclprocating thread | X Reclprocating thread:A screw that makes the slldle block reclprocate without changing the rotation direction of the spindle. |
What's ALM's lead screw advantages?
●ALM's rolled thread Trapezoidal screws and high performance Trapezoidal nuts are combined to provide the optimum performance.The highly burnished surface finish of the screw and low friction bronze and plastic nuts yield a smoother, less abrasive action than conventional cut Trapezoidal screws. Improved wear and surface properties insure the lead screw a longer service life and quieter operation, widely applied to a wide variety of applications.
●Most sizes of Trapezoidal screws are made in large volume and their widespread popularity makes them the least costly of all power screws.
●All Trapezoidal screws have lead angles of 5° or less making them self-locking. Trapezoidal screws will not backdrive under most conditions. This eliminates the need for brakes or other holding devices to sustain loads after positioned.
Trapezoidal lead screws and nuts are widely used and well suited for both manual and power drive applications including:
•Pharmaceutical machinery
•Packaging machinery
•Slide drives
•Metric valve stems
•Medical device drives
•Farm machinery
•Screw press drives
