Lubrication Checkup: Greasing Your Motors

lubrication-checkupSymptom:
“As a greaser for an auto part manufacturer, I’ve noticed an increase in the number of replaced fractional and low-horsepower motors I now have to grease. Most of the replacement ‘offshore’ motors all have grease nipples, but they don’t seem to last as long as the ones without nipples. Any suggestions for grease amount and schedule for these ‘greasable’ motors?”

Diagnosis:
This seems to be a common dilemma in light of more fractional and low-hp motors coming from offshore suppliers. The majority of these units are fitted with one or two grease nipples to lubricate the motor’s bearings, yet, due to cost and physical motor size, relatively few have any form of lubricant drain positioned opposite the nipple(s).

Normally found in motors of 25 hp and higher—depending on bearing design and set up-most larger motors have drain relief ports located 180˚ opposite the greasing point. When greasing the motor, the lubricator is required to unscrew the relief drain port dust cap prior to lubricating the bearing. If the bearing is over-lubricated—as it most often is—the grease is allowed to benignly drain through the unsealed bearing and out the drain port. The lubricator then cleans the port and screws the dust cap back in place.

If the dust cap is in place when the bearing is lubricated—or no drain relief port exists—over-lubrication causes excess grease to bypass directly into the motor’s windings. This will start to hydraulically retard the motor, causing it to overheat and fail prematurely. Meanwhile, the motor will require a huge amount of additional electrical energy to overcome the fluid friction of the surplus grease.

Prescription:
Lubrication delivery system manufacturers who have been applying lubricants successfully since the 1920s have always subscribed to the unwritten rule NOT to lubricate motors of 50 hp or less that have sealed bearings. Because a rolling element bearing only requires 40% of its cavity to be filled with grease, “run-to-fail” strategies have proven more effective than “kill-it-with-kindness” over-greasing. With small and fractional hp motors, a very small amount of over-greasing can quickly become problematic. A better approach would be to replace the grease nipple with a plug and run-to-fail. MT

Introduction

Welcome to Bannister’s Bookshelf, the new Maintenance Technology literary review column! As you may already know, each profession relies on a “Body of Knowledge” that acts not only as a blueprint for recalling previously learned methods and practices, but more importantly, as a tool to stimulate new learning and understanding. In my maintenance management consulting practice, I typically have found that most maintainers do not possess a personal technical library. Instead, they tend to rely on their companies’ technical libraries for their reference materials—if such libraries and actually materials exist at their sites! Unfortunately, most maintenance technical libraries tend to be heavily stocked with catalogs and proprietary vendor information, and are rather “thin” on good maintenance practitioner and management books.

The past 25 years have witnessed major changes in the maintenance profession, with a higher focus on diagnostics, failure understanding and failure prevention than on repairs. During this time, there has been a literary explosion of first-rate maintenance publications that most maintainers are unaware of. In today’s maintenance world, if maintainers are not updating and refreshing their knowledge by reading current maintenance books and periodicals, they run the real risk of becoming isolated and stagnant within their profession.

When asked about their reluctance to personally invest in a maintenance library, most say that they would like to do so, but are hesitant to lay out what might be a considerable amount for a maintenance book. The reason, they admit, is that they doubt their ability to choose a book that will deliver value for the money spent.

That’s where Bannister’s Bookshelf comes in. It will focus on reviews of books that relate directly and indirectly to the maintenance function and allow you, the maintainer, to “try before you buy!”

Read the reviews that you will be finding here. If a book appears to interest you, ask your local library to obtain it for you. Then, carve out the time to read it and decide if you would like to buy it for your personal “Body of Knowledge.” Although most of the reviewed titles will be recent publications, you also can count on me to slip in an occasional must-have “oldie but goodie.”

The goal of Bannister’s Bookshelf is to make the maintainer—and the maintenance department—aware of books specifically published for and aimed at the maintenance profession. Over time, this column will review a number of books and categorize each as follows:

  • Title: the book’s name
  • Audience: answers the question “is the book directly targeting maintenance as the primary audience or indirectly targeting maintenance as the secondary target audience?”
  • Maintenance Classification: four classifications – 1) Management; 2) Technology; 3) Practical; 4) Reference
  • Author: the writer’s name
  • Publisher: the company that publishes and prints the book
  • Internet: the Web address of the publisher for more information on the book
  • ISBN Number: the book’s Library of Congress unique ID number
  • Price: the book cost
  • Year: year the book is published
  • Index: indicating if the book has an index
  • Bibliography: indicating if the book has a bibliography
  • Review Outline: the section where I, the reviewer, get to say a few words about the book

Now, take a look at our reviews…

Solution Spotlight: Unitized Split Seals Will Simplify Your Life

A cost-effective alernative to equipment teardown

According to Chesterton, its patent-pending 33K split seal is not only quick to install and reliable, it has proven to outperform conventional lip seals.  Its innovative split technology prevents penetration of external contaminants from entering the housing to provide excellent service in bearing and gearbox applications, among others.

split-seals

The 33K is manufactured using Chesterton’s unique machining process that eliminates the need for tooling costs associated with new sizes. The seal can be installed in either direction, thus allowing the end user to locate sealer rings away from a previously damaged shaft. Based on the product’s unitized assembly, time required for installation can be reduced from hours to minutes.

Materials that outperform conventional oil lip seals
The 33K incorporates two different high-performance types of materials:

  • The unitized housing is made from abrasion-resistant thermoset polyurethane that energizes and provides easy mounting to the equipment.
  • The sealing interface is made from high-performance, filled PTFE material developed specifically for sealing applications.

Fast, easy and reliable

  • Split design eliminates the need for and associated cost of equipment disassembly.
  • No equipment modifications are necessary. All seals are made to order. MT

The Green Edge

Torque Certification Program Targets Wind Professionals

snap-on-industrial

To meet the needs of the growing global wind industry, Snap-on Industrial has launched a torque certification program, which explores torque theory and proper use and application of equipment.

“The understanding and proper application of torque is a mission-critical element of a viable and sustainable wind-power industry in the U.S.,” said Frederick Brookhouse, business and education partnership manager, Snap-on Industrial.

Developed in collaboration with educators, the 16-hour course is designed as a component to an existing wind-power technician training course. The Snap-on torque certification program will be integrated into wind-power technician courses currently available at Lakeshore Technical College, Cleveland, WI; Gateway Technical College, Kenosha, WI.; Texas State Technical College, Sweetwater, TX; Cerritos College, Cerritos, CA.; and the multi-campus Frances Tuttle Technology Center in Oklahoma.

The torque curriculum includes modules on theory, technique, mechanical torque wrenches, electronic torque wrenches, hydraulic torque wrenches, torque multipliers and safety. The program is designed to cover all aspects of torque, from the basics through master-level skills.
