Train Your Eyes To Spot Gearbox Failure

Your gearbox is constantly communicating via sounds, temperatures, and other important cues. But can you tell the difference between signs of normal operations - and potential catastrophic failure? Webinars Courtesy of Philadelphia Gear

4 When a Good Gear Drive System Goes Bad (October 2012)

Even when the critical components of industrial power transmission gear drive systems are properly designed, specified and manufactured consistent with application requirements, performance problems can develop over time and failure may follow.

5 Gear Design Effects on Performance of High-Speed Helical Geartrains as Used in Aerospace Drive Systems (March 2016)

The performance of high-speed helical geartrains is of particular importance for tiltrotor aircraft drive systems. These drive systems are used to provide speed reduction/torque multiplication from the gas turbine output shaft and provide the necessary offset between these parallel shafts in the aircraft. Four different design configurations have been tested in the NASA Glenn Research Center, High-Speed Helical Geartrain Test Facility. The design configurations included the current aircraft design, current design with isotropic superfinished gear surfaces, double-helical design (inward and outward pumping), increased pitch (finer teeth), and an increased helix angle. All designs were tested at multiple input shaft speeds (up to 15,000 rpm) and applied power (up to 5,000 hp). Also two lubrication, system-related, variables were tested: oil inlet temperature (160–250° F) and lubricating jet pressure (60–80 psig). Experimental data recorded from these tests included power loss of the helical system under study, the temperature increase of the lubricant from inlet to outlet of the drive system and fling-off temperatures (radially and axially). Also, all gear systems were tested with and without shrouds around the gears.

6 Lubrication of Plastic Worm Gears (August 2019)

In the selection of lubricating greases for plastic worm gears, the user needs to know the influence of each grease constituent on the tribological performance in order to choose the appropriate lubricant. In this work, the effect of NLGI class, viscosity, base oil and thickener type are investigated separately regarding the efficiency and temperature close to the tribocontact. With the help of this contribution the user understands the effect of each parameter and learns about the potentially reachable efficiency and temperature ranges.

7 A Model for Shear Degradation of Lithium Soap Grease at Ambient Temperature (October 2017)

In this study the mechanical shear degradation of lithium-thickened grease was evaluated using an in-house-developed aging rig and a commercial rheometer. It was found that this grease loses its original consistency during aging and shows a two-phase aging behavior. In the first phase, primarily reorientation and breakage of the thickener network take place, resulting in a progressive drop in the grease's rheological properties. After this, the aging is dominated by the breakage of smaller fiber fragments and the grease degrades at a much slower rate.

8 Bearings for High Temperatures (Fall 2007)

When rolling element or sleeve bearings operate under extreme conditions, it’s more important than ever to follow proper lubrication selection and maintenance procedures to maximize eff ective life and effi cient performance.

9 Prediction of Heat Generation in Transmission Bearings by Application of FEM (September 2018)

Heat generation in bearings is manifested by the power losses of the transmission. Because of the rise in temperature due to heat generation, the appearance of dilatation adversely affects the bearings' geometrical characteristics.

10 The Maintenance of High Quality and Taste (September 2020)

Valves help control temperature, pressure and viscosity for alcohol fermentation.

11 High-Performance Plastics (October 2019)

Custom PEEK Compounds have led to the development of transmission seals and thrust washers that offer lower wear, friction and temperature advantages.

12 Service Without a Smile (April 2010)

Manufacturing employees have always kept their eyes on the robotic systems that continue to pop up in assembly lines and industrial workspaces. These metallic, low-maintenance robotic employees don’t waste time with smoke breaks or catching up on episodes of Lost. They tend to stick to the task at hand with little argument or attitude, giving human counterparts a bad name when they gripe about factory temperatures or lack of a decent dental plan.

13 Flexible Options with Flexible Shafts (August 2013)

You need to transmit a rotary motion where no straight line is possible. Or, you need to allow for some uncontrollable misalignment. How about transmission taking place between moving components? What if you need to control something in hazardous locations where you cannot directly handle the application, such as high-temperature environments, under hazardous conditions or in clean room applications? Functionally designed flexible shafts can meet all these challenges.

14 With Electric Motors, Size Indeed Matters (February 2009)

In this paper, Edward Hage, founder of specAmotor.com, an online motor calculation and selection tool, focuses on the overheating of electric motors. Presented here is a calculation method with which the temperature and heat development of a direct current (DC) motor and a brushless motor can be predicted accurately.

15 Improved Performance for Hydraulic Seals from Thermoplastic Polyurethane (June 2012)

Seal design engineers and end users are continually seeking improved sealing systems and materials. This paper describes the potential of a new thermoplastic polyurethane (TPU) material to deliver improvements in pressure, speed and temperature capability, which are presented as comparisons to proven industry standard materials. Performance is demonstrated by virtue of test bench results of seals made from MDI-, PPDI- and NDI-based materials.

16 Motor Appreciation (April 2014)

When I woke up this morning, my house was a comfortable 68°F, despite the fact that overnight temperatures in the Chicago area were close to freezing. I don’t often think about the blower motor that helps circulate the warm air from my furnace throughout my house, but today I was grateful for it...

17 Belts Vs. Couplings (August 2015)

rotary-type blowers? Examples: for motor KW; RPM; temperature; pressure production; lifetime; etc. In other words, how do I choose between belts or couplings?
