Lead screw transmission efficiency
Mechanical efficiencies for Trapezoidal lead screws range from 20% – 40% depending upon the lead angle, coefficient of friction and nut material. Plastic nuts offer approximately 10% – 20% better efficiency than bronze because of their lower coefficient of friction when running against steel screws.
All ALM Trapezoidal screws have lead angles of 5° or less making them self-locking.Trapezoidal lead screws will not backdrive under most conditions. So you no need consider brakes or other holding devices to sustain loads for trapezoidal screws. All other screws except Acme series require some braking,that is to say,to prevent backdriving.
How to select lead screw nut?
When selecting the right nut for an application, there are a few things to keep in mind,bronze nut provide superior service at high working loads.They should be well lubricated with a good quality, Extreme Pressure (EP) grease compatible with the operating environment.plastic nuts can be used without lubrication and are popular for low load applications.
T ISO Trapezoidal Thread Din103
For transmission and position adjustment, widely used in the mechanical industry.
H High-helix Screws
A high-helix leadscrew, speedy multi-start lead screw, or steep lead screw features a high pitch that is used to transform a smaller radial movement into a large axial movement.
M ISO Metric Thread (60° )
The most common form of thread used for fastening and precision transmission.
A ACME Thread (29° )
Inch threads can also be used for fastening connections, but not for high accuracy.
R Knuckle Thread
With the same arc thread as ball screw, the transmission is smoother.
G Gothic thread
Gothic double arc thread, offering the advantages of ball screw, is similar a new kind of lead screw.
X Self-reversing thread
A screw that makes the slide block reciprocate without changing the rotation direction of the spindle.
