Helical Planetary Gearboxes: Understanding The Tradeoffs
The choice between helical and spur gears in planetary gearboxes may seem straightforward. Go with helical gears if you want the gearbox to run as smoothly and quietly as possible. Choose spur gears when you need to maximize the gearbox’s torque density or working life … [Read more...]
Deliver the most efficient, precise performance
Ball screws are mechanical linear actuators that convert rotary movement into linear motion with little friction, which boosts efficiency. Due to this efficiency, ball screws are ideal for a variety of industrial and automotive applications such as milling-machine tables, robotics and semiconductor … [Read more...]
Saving energy and service cost with electric linear systems
Today we are seeing a major shift from pneumatic linear actuators to electromechanical systems. This is because of high maintenance requirements of pneumatic and hydraulic systems which results in long machine downtimes and lost productivity. But can electrical linear systems truly fill in as a … [Read more...]
Do You Know the Basics of Thermal Expansion?
Motion systems with very long length capabilities like the LoPro® Linear Actuators from Bishop-Wisecarver may require careful evaluation. Thermal expansion is one of the problems that can plague your long motion system application, but it doesn’t have to be! Basics of Thermal Expansion is a … [Read more...]
The Long-Term Advantages of Linear Piston Free Pumps and Aerators
This paper examines the idea of design simplicity as it relates to compressors and vacuum pumps comparing and contrasting conventional design (i.e., motor-driven and diaphragm) with the linear motor free piston system design. … [Read more...]
Selecting Linear Encoder Technology: Design Challenges, Considerations and Solutions
When building a machine, OEMs and end-users are faced with the challenge of finding the highest possible precision technology, while meeting demanding price-performance ratios. Learn more about the challenges designers face and what types of linear encoder technology options should be considered … [Read more...]
How to Build a Better Linear Drive System
With advances in precision manufacturing and the advent of electronic preloading, the accuracy and performance of rack-and- pinion drives can match or exceed that offered by competing hardware – often with better durability, efficiency and economics. This paper outlines four key areas for comparing … [Read more...]
Forms of Closed Loop Stepper Control
This White Paper will explain the three methods that are used to close the feedback loop around stepper motors in a control system. … [Read more...]
