Reduce Down Time with Torque Limiters
With wood being one of the few renewable resources, its use continues to grow. But the automation of processing the raw material comes with its own challenges. By their very nature, wooden logs are inconsistent in size and density. Although converting tolerances are much larger than metal or plastic components, it's this variation that presents problems in high-speed automated processing. A customer of ours presented us with a problem they were having with their automated de-barking machine. The basic design included a large number of rollers and cutters that sheared the bark off raw [...]
Torque Limiter Finds Drive Problem During Machine Test
Installing some type of torque limiting device in your machine system is very often a wise idea. This is especially true where there is human interaction, but it’s also smart to include them in other types of processing equipment. A common objection to designing them into standard machine designs is that they sometimes cost more than the components they are thought to protect. But that’s really a secondary consideration. The prime reason to add them to machine designs is to eliminate the downtime associated with removing damaged components, finding replacements, and installing new ones. [...]
A Quick Connection Improves Efficiency
Short-run printing and automated machining require solutions for quick tool changes to achieve customized production efficiently. Two different applications use the same design concept to solve this problem. In the first application, a manufacturer of printing presses was looking for a quick-connect device to speed up cylinder changes. With short-run printing becoming the norm, print cylinder changeover was eating up a lot of production time. In the past, a transfer gear was installed on the cylinder shaft journal. However, because of a gear error, some motion variations were created. The new design was to [...]
Why do Replacement Gearboxes fail?
Have you ever replaced a failed gearbox, whether it just wore out after years of faithful service or it crashed and burned as the result of a major jam? Have you ever had said gearbox mysteriously fail again after only a day or a week or a month? Whether you are a user, a distributor who sold it to the user, or an OEM providing service to the user, the situation can be extremely frustrating. Unfortunately the reason for the failure probably wasn’t because of what you were thinking. We don’t get the calls [...]
Mechanical Drive Design For Satellite Dish Positioning
The need for communication and data transfer are growing at a staggering rate. More satellites and more dishes are being put into service on a daily basis to satisfy and utilize the technological advances. While we have written about satellite dish applications before, there has been a recent explosion of inquiries from various companies producing these products in different sizes. The inquiries include large land-based satellite dish positioning drive designs and mobile applications used by the media, government agencies, and the military. In the most recent applications, the requests have been for system [...]
