- Servo motor VS stepper motor: How to choose?The vast majority of linear motion applications use a stepper or servo motor to provide torque to a drive mechanism,which is usually a ball screw or lead screw,rack and pinion,or belt and pulley system.Servo motors and stepper motors are designed for very different performance characteristics.DetermApplication March 29, 2023
- What should we pay attention to when using ball splines?The Spline Nut and the Spline Shaft●Do not remove the spline nut from the spline shaft unless necessary.If the spline nut is reinstalled to the spline shaft after the inevitable removal of the nut,the ball position on the spline nut should be aligned with the groove position of the spline shaft,andApplication March 30, 2023
- What are the common applications of hybrid stepper motor linear actuators?For electromechanical linear actuators,integrated design saves space,reduces complexity,and reduces total cost of ownership,while reducing the number of parts required for repair or replacement.The hybrid stepper linear actuator is a design with multiple uses in medical,3D printing and assembly applApplication March 31, 2023
- How to select end fixity conditions for ball screw applications?The ball screw assembly consist of three main components:ball screw shaft,ballnut and end support bearing.The end support bearing is more than just an accessory,it has a significant impact on the stiffness,maximum speed and buckling load of the ball screw assembly.There are four combinations of endBall Screw April 03, 2023
- How to choose the best linear motion components for your application?●Lead screwThe lead screw uses the helix angle of the thread to convert the turning motion into a linear motion.The large area of sliding contact between male and female thread leads to relatively high friction loss.As a result,the lead screw is less efficient and less accurate than the ball screw.LBall Screw April 04, 2023
- How to choose the right linear guide?In the case of optimal cost,the linear guide that meets the actual service requirements such as equipment accuracy requirements,load requirements,and life requirements is selected as the appropriate linear guide.A.Determine the accuracy level of the guide rail according to the equipment accuracy reqBall Screw April 06, 2023
- What are the common materials of plain bearings?Most metal plain bearings are made of bronze.They have the highest load capacity of all three types and are resistant to corrosion.However,they introduce metal-to-metal contact with the shaft,which can lead to wear if proper lubrication is not maintained.Lubrication of bronze bearings must be suppliBall Screw April 07, 2023
- How to choose the right diameter and lead for the lead screw?●Determine the axial loadLead screws are commonly used in linear actuators and positioning devices to provide thrust(axial)force to drive the load.The axial force that the lead screw assembly can withstand depends on the diameter and lead of the lead screw and the material of the nut(plastic or bronBall Screw April 11, 2023
- How to know the lead screw is suitable for your application?●Load capacity of lead screwPlastic nuts are suitable for light loads of less than 100 pounds,although plastic nuts of 300 pounds and up can be designed.Bronze nuts,on the other hand,can be used in applications over thousands of pounds.If the load requirements exceed the lead screw capacity,ball scrBall Screw April 13, 2023
- What is the difference between backlash and hysteresis in linear systems?In linear systems,backlash and hysteresis are often referred to as the same phenomenon.But while they all cause loss of motion,they do so for different reasons and in different ways.Backlash is caused by clearance or play,between mating parts,and dead bands are introduced when the direction of traveBall Screw April 12, 2023
