To begin the design of the CD Drive’s main stage, an engineer would first do a quick assessment to ensure that the force that can be exerted on the stage by the motor at its peak operating efficiency torque is capable of acceler-ating the stage at the desired acceleration. Motor_gearbox_leadscrew.xls shows the type of calculations needed.

When designing spur teeth, is there a formula/guideline/design guide for determining the amount of crowning? 18 Gear Design (December 2017) Our expert explores standard vs. optimized gears, as well as high contact ratio gearing. 19 Gear Design Software, Engineer Beware (February 2014) When software goes bad, what do we call it? System failure?
Design Engineer's Guide - Selecting a Lubricant for Ball Screws Many parameters must be considered when designing or selecting a ball screw assembly. Operating load, speed, accuracy, environment, and power requirements all play major roles in the design criteria.
Design Engineer's Guide: Selecting a Lubricant for Ball ... A ball screw assembly must be thoroughly cleaned to remove all contaminants before lubrication and re-lubrication. Contamination is a leading cause of premature failure of ball screws.

component design life as follows: • Shelf life of the grease-lubricated bearing/component represents the period of time prior to use or installation. • The shelf life is a portion of the anticipated aggregate design life. It is impossible to accurately predict design life due to variations in lubricant bleed rates, oil migration, operating
Ball screws are robust and economic linear positioning systems that are widely employed in high speed and high precision machines. Due to precision and stability requirements, the preload force has been considered one of the main parameters in order to define the axial rigidity and the maximum axial ...
Air Bearing Guides Air bearings can be run on different types of guide material. Common guide surfaces include granite, hard-coated aluminum, ceramics, glass, stainless steel, and chromed steel. Guide Surface Considerations Surface finish, local flatness issues and possibly even holes in the counter surface need to be taken into consideration.
