Lead of Screw Solution

STEP 0: Pre-Calculation Summary

Formula Used

Lead of Screw = Pitch*Number of Threads
L = P_screw*n
This formula uses 3 Variables

Variables Used

Lead of Screw - (Measured in Meter) - Lead of Screw is the linear travel the nut makes per one screw revolution and is how ball screws are typically specified.
Pitch - (Measured in Meter) - Pitch is the distance between screw threads and is commonly used with inch sized products and specified as threads per inch.
Number of Threads - Number of Threads is total no. of threads in a screw.

STEP 1: Convert Input(s) to Base Unit

Pitch: 5 Meter --> 5 Meter No Conversion Required
Number of Threads: 16 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

L = P_screw*n --> 5*16

Evaluating ... ...

L = 80

STEP 3: Convert Result to Output's Unit

80 Meter --> No Conversion Required

FINAL ANSWER

80 Meter <-- Lead of Screw

Force at Circumference of Screw given Helix Angle and Coefficient of Friction

Go Force Required = Weight*((sin(Helix Angle)+Coefficient of Friction*cos(Helix Angle))/(cos(Helix Angle)-Coefficient of Friction*sin(Helix Angle)))

Torque Required to Overcome Friction between Screw and Nut during Lowering Load

Go Total Torque = Load*tan(Limiting Angle of Friction-Helix Angle)*Mean Diameter of Screw/2

Torque Required to Overcome Friction between Screw and Nut while Lowering Load

Go Total Torque = Load*tan(Limiting Angle of Friction-Helix Angle)*Mean Diameter of Screw/2

Torque Required to Overcome Friction between Screw and Nut

Go Total Torque = Load*tan(Helix Angle+Limiting Angle of Friction)*Mean Diameter of Screw/2

Helix Angle for Multi-Threaded Screw

Go Helix Angle = atan((Number of Threads*Pitch)/(pi*Mean Diameter of Screw))

Force at Circumference of Screw given Helix Angle and Limiting Angle

Go Force Required = Load*tan(Helix Angle+Limiting Angle of Friction)

Helix Angle for Single Threaded Screw

Go Helix Angle = atan(Pitch/(pi*Mean Diameter of Screw))

Helix Angle

Go Helix Angle = atan(Lead of Screw/Circumference of Screw)

Lead of Screw

Go Lead of Screw = Pitch*Number of Threads

Lead of Screw Formula

Lead of Screw = Pitch*Number of Threads
L = P_screw*n

What is lead?

Lead is the linear travel the nut makes per one screw revolution and is how ball screws are typically specified. The pitch and lead are equal with single start screws. For multiple start screws the lead is the pitch multiplied by the number of starts.

What is a lead screw mechanism?

A lead screw turns rotary motion into linear motion combining a screw and a nut where the screw thread is in direct contact with the nut thread. In the case of roller screws, the rollers rather than the nut are in direct contact with the screw thread offering greater efficiency.

How to Calculate Lead of Screw?

Lead of Screw calculator uses Lead of Screw = Pitch*Number of Threads to calculate the Lead of Screw, Lead of Screw is the linear travel the nut makes per one screw revolution and is how ball screws are typically specified. The pitch and lead are equal with single start screws. For multiple start screws the lead is the pitch multiplied by the number of starts. Lead of Screw is denoted by L symbol.
