In case you missed them, following are three recent blog postings by our popular PTE bearings blogger - Norm Parker. We also felt that, should you not be a blog follower, this would be a good way to introduce you to Norm's bearings wisdom. Parker is currently the global senior specialist/roller bearings at Fiat Chrysler Automobiles (FCA).
I'm not able to get a good connection
between the pulley and shaft in my drive
assembly. Could you explain the various
ways of connecting a pulley to a shaft to
prevent the pulley from slipping?
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.
