Debunking the Myths of Hydraulic to Electric Actuator Conversion

Debunking the Myths of Hydraulic to Electric Actuator Conversion

With rugged and reliable operation, simple installation, and lower costs, electric actuators are paving the way for significant control and productivity improvements in off highway machinery.  A new White Paper from Al Wroblaski, Linear Actuator Product Manager, Thomson Industries, Inc.

Many manufacturers of off-highway equipment have replaced hydraulic cylinders with electric actuators in order to eliminate pumps, hoses and valves, and make vehicles smaller, lighter and quieter.  They have taken advantage of the flexibility in interfacing with control systems to provide a wide range of new features and capabilities.  For example, electric actuators can easily interface with a vehicle controller for complex motions such as cycling for a specified number of times at various positions, resulting in improved off highway machine performance and productivity.

Today the benefits of electric actuators can be realized in applications with static loads up to 5000 lbs and dynamic loads up to 3000 lbs., with load ratings increasing each year.  For now, hydraulic cylinders are required for higher loads or when moving loads at 100% duty cycle.

But certain myths have arisen about electric linear actuators that have slowed their adoption in many applications where they potentially offer substantial OEM and end-user advantages.  The rest of this article will take a close look at these myths and discuss the opportunities for integrating electric linear actuators in off-highway vehicles and machinery including recreational vehicles, sprayer booms, snow blowers, turf, garden, construction and agricultural equipment.

Myth #1: Electric actuators can’t handle a harsh environment…

5 Key Tips for Linear Bearing Maintenance

A White Paper from Al Ng, Director, Engineering — Thomson Linear Bearings and Guides

How a $25 Investment Now Can Prevent Tens of Thousands of Dollars in Unplanned Downtime.   5 Key Tips for Proper Linear Bearing Maintenance.

Now is the time to start avoiding expensive unplanned downtime by implementing a regular schedule for bearing lubrication and replacement. Proper lubrication is required for rolling element bearings to last, even under light loads. The dynamic load capacities listed in the catalog depend upon appropriate lubrication intervals. For low loads or higher speed low drag applications, machine oil may be sufficient. Oil flows more freely through the bearing, flushing out contaminants but also requiring more frequent re-lubrication. Grease should be used for moderate to high load applications. The higher viscosity provides better adhesion and the channeling properties allow for less frequent lubrication.

A typical minimum lubrication cycle is once a year or every 100 km of travel, which ever comes first. More frequent lubrication may be required based on application specifics, like the duty cycle, usage, and environment…

Power Off Brake Backlash. What you need to know.

Author- Rocco Dragone, Deltran Product Specialist, division Thomson Industries

Power Off Brakes, sometimes referred to as Safety Brakes, Spring Set Brakes or Fail Safe Brakes, are widely used in the industry, usually on the back of motors, to hold a machine, pulley, Z axis, or robotic arm in position in case of a power failure.

There are many application and technical issues that arise when it comes to utilizing Power Off Brakes.  One of the most common issues has to do with backlash in the brake, or what is described as lash, free play, or lost motion.  Backlash is defined as how much or how many degrees (+and-) the shaft will rotate (lost motion) while the brake is holding (no power). This depends on the type of “hub” or “drive”….

Selecting and Sizing Ball Screw Drives

Reprint of Thomson Industries, Inc. Article by Jeff G. Johnson

Thomson Ball Screw Family

Thomson Ball Screw Family

The ball screw drive is an assembly that converts rotary motion to linear motion and vice versa.  The ball screw drive consists of a ball screw and a ball nut with recirculating ball bearings.  The connection between the screw and the nut is made by ball bearings that roll in the matching forms in the screw and ball nut.  The forces transmitted are distributed over a large number of ball bearings, giving a comparatively low relative load per ball.  With rolling elements the ball screw drive has a very low friction coefficient.  Ball screw drives typically provide mechanical efficiency of greater than 90% so their higher initial cost is often offset by reduced power requirements.

Stepper Motor Linear Actuators 101

What exactly is a Stepper Motor Based Linear Actuator?

Need to know how a Stepper Motor Linear Actuator works?

Suppose you, as an engineer, are tasked to design a machine or part of a machine that requires precise linear positioning.   How would you go about accomplishing this?  What is the most straightforward and effective method?

Haydon Kerk Stepper Motor Linear Actuator White Paper

Haydon Kerk Stepper Motor Linear Actuator White Paper

When students are trained in classic mechanical engineering, they are taught to construct a system using conventional mechanical components to convert rotary into linear motion.   Converting rotary to linear motion can be accomplished by several mechanical means using a motor, rack and pinion, belt and pulley, and other mechanical linkages.   The most effective way to accomplish this rotary to linear motion, however, is within the motor itself.

This White Paper, from Haydon Kerk Motion Solutions, discusses the technology behind stepper motor linear actuators, what makes them different, and concludes with a detailed example illustrating how they should be sized to move a given load.   Click on the link below to download it.

Linear Bearings and Guideways Primer

Linear bearings and guideways are primarily used in positioning table (positioning stage) applications.  The main function of a positioning table’s linear or rotary bearing system is to carry the user mounted load while the table is in motion.  The bearings are also a key element in determining the overall positioning table accuracy, repeatability, straightness and flatness.  Each bearing design provides advantages and disadvantages in load capacity, size, cost, stiffness, and friction.  Selecting the right linear or rotary bearing system for a positioning table application is critical.

The four primary linear bearings used in positioning table applications are cross roller, round rail, square rail, and air bearing.

Cross Roller Linear Bearings feature cylindrical rollers with ground “V” ways.  The larger surface contact between the rollers & “V” ways typically increases the table load capacity by up to 3 times more over a comparable ball & rod type system.  These table designs also produce better flatness and straightness specifications over traditional ball & rod type systems.  Thus cross roller linear bearings are typically used in higher accuracy type of applications.  However, the disadvantages of this type of bearing system are short travel lengths, minimal moment load capacity, large horizontal envelope area, and no possibility of using protective cover plates or waycovers.

Cross Roller Linear Bearing

Cross Roller Linear Bearing

Round Rail Linear Bearings use four bushings with recirculating ball bearings which are mounted within either two, or four pillow blocks (aluminum or steel housings).  The pillow blocks are then mounted to the underside of the carriage, which rides on two round hardened & ground shafts (which are mounted to the base).  Travel lengths are only limited by the available shaft and base length.  The contact point between the recirculating balls in the bushing and the round shaft produces a very low friction positioning table.  The greater number of balls contacting the ground shaft provides for a larger load capacity system.  This table design provides long travel lengths, good load capacities, large moment load capacities, and can accommodate protective cover plates & waycovers.

Round Rail Linear Bearing

Round Rail Linear Bearing

Square Rail (linear guide) Bearing Systems are very similar in operation as the round rail systems.  The round shaft has been replaced with a rectangular (square or T-shaped) rail, while the round rail bushing has been replaced with a rectangular bearing block.  The recirculating ball bearings in the bearing block contact more surface area on the curved ball race on the square rail which provides a table that has increased load capacity, increased moment load capacity, and higher system rigidity over the round rail positioning table.  Because of the precision ground ball races on the rails, these linear bearings will have better flatness & straightness specifications than a round rail system.  Table travels are only limited by the available rail, and base length.  This table design is also able to handle shock & vibration forces better than a round rail system due to its robust bearing design, and can accommodate protective cover plates & waycovers.

Square Rail Linear Bearing

Square Rail Linear Bearing

Air Bearing Linear Tables create a small air cushion between the table carriage and the table base (guide rail).  This provides a non-contact linear bearing system that is rigid, friction free, and cog-free.  Using a very accurate guide rail (rectangular or square) can produce excellent flatness & straightness specifications, especially if the air bearing linear table is mounted to a granite base.  Typical drive mechanisms for these tables include high accuracy acme screws and linear motors.  Incorporating a high accuracy non-contact linear motor drive system with a high accuracy non-contact linear encoder for position feedback creates a very accurate sub-micron or nano-precision positioning table, one that could virtually last forever.

Maximize reliability and performance of actuator drive systems by minimizing electrical noise

A New White Paper from Tolomatic .  Published January 28, 2014

Is your actuator drive system subjected to harsh factory conditions that include dust, moisture, heat or vibration?  If so, then chances are electrical noise is the culprit that can disrupt actuator signal controls, cause erratic motion, or in some cases, complete system failure if left unchecked.

Although system noise can never be completely eliminated, Tolomatic’s new white paper  will help you identify and minimize the causes of electrical noise in drive systems to increase system performance.

This white paper will cover:

  • What causes ground loops and how to mitigate ground loop noise
  • The common causes of electromagnetic interference (EMI) and how to minimize the effects with proper switching and cabling practices
  • Best practices for reducing the risk of communication outages and preventing network storms
