Equipment downtime and reduced component
life are a few of the consequences — and
potential costs — of using the wrong seals on many types of industrial equipment including pump bearing frames, electric motors, fans, pillow blocks, gearboxes and more. However, if
correctly specified and installed, seals provide effective barriers that both retain lubricants as well as protect against water, corrosion, debris and other contaminants.
Eddy Swiben, branch manager at BDI
Canada, explains how to problem solve
on an automatic cutter for tissue rolls.
“This is a very major paper tissue manufacturer that sells paper tissue rolls all over America.” They roll paper tissue just like newsprint paper mills do. When the product is finally done and dried, they need to roll it on a light carton core 20-ft. long.
Bearings are an essential component
in the majority of mechanical
designs and equipment.
It is important to consider the
most effective materials when designing
industrial machinery, especially in
applications where water or other liquids
are present. Many materials will
be unable to overcome the challenges
associated with operating in a wet or
corrosive environment.
It's no secret that conveyor systems are the primary market for gearmotors, and so it shouldn't be much of a surprise that gearmotor manufacturers are looking for ways to cater to that market's needs. From Brother's new VFDs to Siemens' Simotics S-1FG1, a lot of the new solutions in the industry have their own unique quirks, but all fall into a few common veins.
Here’s what we know about Tremont, Illinois: It’s a small village in Tazewell County, (population 2,400+), holds an annual summer turkey festival
(quite popular) and the courthouse is a famous historic site where politician James Shields challenged an “up-and-coming” lawyer named Abraham Lincoln to a duel with cavalry broad swords (they showed up, but the duel never materialized). In 2016, you can add FIRST Robotics Competition World Champion to the village’s rather eccentric list of accomplishments.
Until now the estimation of rolling bearing life has been based on engineering models that consider an
equivalent stress, originated beneath the contact surface, that is applied to the stressed volume of the
rolling contact. Through the years, fatigue surface–originated failures, resulting from reduced lubrication or
contamination, have been incorporated into the estimation of the bearing life by applying a penalty to the
overall equivalent stress of the rolling contact. Due to this simplification, the accounting of some specific
failure modes originated directly at the surface of the rolling contact can be challenging. In the present
article, this issue is addressed by developing a general approach for rolling contact life in which the surfaceoriginated
damage is explicitly formulated into the basic fatigue equations of the rolling contact. This is
achieved by introducing a function to describe surface-originated failures and coupling it with the traditional,
subsurface-originated fatigue risk of the rolling contact. The article presents the fundamental theory of the
new model and its general behavior. The ability of the present general method to provide an account for
the surface–subsurface competing fatigue mechanisms taking place in rolling bearings is discussed with
reference to endurance testing data.
For the lubrication of open gear drives
used in different industrial applications
such as cement and coal mills,
rotary furnaces, or where the sealing
conditions are difficult, semi-fluid
greases are often used in preference to
fluid oils. For girth gear applications
the greases are used with a splash or
spray lubrication system. The selection
of such greases influences pitting lifetime
and the load-carrying capacity of
the gears, as well as wear behavior
Ernest Head (Arnie), CBS and technical
sales representative at Motion Canada
helped save a lumber industry customer
time and money by adapting a bearing
solution for another client. Here’s how:
When trying to find a new bonding material dispense system, one manufacturer tested a series of pumps — all of which leaked due to the abrasiveness of the bonding material. The manufacturer also had been attempting to manage shot size
manually with their previous system, and was not able to keep dispense consistent. The company searched for
a system that could accurately dispense programmed shot sizes while also eliminating the leaking issues they
had experienced with previous pumps. Graco provided a Check-Mate pump with SmartWare software, and the manufacturer is now able to automatically dispense shots of bonding material as small as one ounce without leaks.
