A Chicago-area bakery was replacing
the tray support bearings in its ovens
on a reactionary basis. Their weekly
inspection cycle was resulting in two
mechanics spending an average of 20
labor hours per week to replace failed
bearings. The premature bearing failures
were caused by a combination of
the high heat and humidity in the ovens,
resulting in lubrication failure and
contamination. When BDI was asked
to recommend a solution, the bakery
was averaging one month of bearing
life in this application.
Specialist power transmission supplier JBJ Techniques Limited, of Redhill, Surrey, England were recently contacted by the staff of Bloodhound SSC R&D engineering team to solve
a problem on the fuel pump test rig. JBJ Techniques had worked with various team members in the past and this previous experience made JBJ an easy choice to assist with this project. The scope of supply was to produce a suitable drive coupling with a maximum diameter of 160 mm, capable of
transmitting 550 Nm @ 10,000 rpm, with as short an assembly as possible, and at the same time be able to accept misalignment within the drivetrain.
rotary-type blowers? Examples: for motor KW; RPM; temperature; pressure production; lifetime; etc.
In other words, how do I choose between belts or couplings?
Bellows couplings first began to be
widely used by machine tool builders
in the mid-to-late 20th century. With the
advent of CNC technology, machine
engineers started looking to improve
upon some of the negative influences
traditional power transmission couplings
can have on a precision rotary /
linear motion system.
