Get PriceTorque = Force x Distance = (Rotational Force acting on a ball bearing) x (radius of ballscrew) So you can calculate the rotational vector component of force based on torque and the radius of the ballscrew. T = F1 x D/2, where: F1 is the vector component (tangent to the ballscrew) of the force applied by the screw onto the ball bearing.
Get PriceA screw is a mechanism that converts rotational motion to linear motion, and a torque (rotational force) to a linear force. It is one of the six classical simple machines.The most common form consists of a cylindrical shaft with helical grooves or ridges called threads around the outside. The screw passes through a hole in another object or medium, with threads on the inside of the hole that ...
Get Price01-10-1997· However, in a screw feeder, especially with long inlet openings, axial force can be very severe. Thus, determination of the axial force is necessary for the design of a screw feeder. Roberts and Manjunath [5] proposed a method by which the torque requirement can …
