Hi all,
I do condition monitoring and over the years 3 gearboxes with exact 2:1 reduction spiral bevel gears have failed with spalling of the pinion teeth at the tips only.
The loads are smooth and about 50% of the design loads for this gear pair.
The following 2 helical gear sets have lower...
Hi,
I'm using a motor cycle engine in the back of a space frame for a single seater hill climb car.
To get 4WD I need to have a stub shaft from the normal gearbox output sprocket and from it use a CF toothed belt to the front axle ass'y.
I want to use a duplex chain coupling and this means...
I am designing/building a small open wheel hill climb car (bitumen track) with a 1 litre motor cycle engine behind the driver. The driver volume will be a CF tub and the engine volume will be a space frame.
I built one in ’68 from ¾” 1/16” wall mild steel and it is still very successful today...
Hi All,
I’ve only recently discovered this forum, after occasionally posting on the machinery vibration forum. I’m a mech eng and live in Melbourne, Australia
I’m again designing a motor cycle powered rear engined hill climb car, all ball joints.
After reading Ortiz & others again and again...
I have been asked to investigate "roll chatter" on a "skin pass" steel rolling mill used for final cold rolling of previously hot rolled, 1 mm thick material for car bodies.
The mill has 2 work roll sizes (450 mm dia for 150 tons and 650 mm for 400 tons) and 2 backup rolls both 1100 mm dia...
Hi all,
I'm designing a hill climb car and want to use metal bellows to hydraulically transmit the force and deflection of each wheel to another belows in central position.
A "warp" suspension system will optimize all wheel movements, google it for details if interested.
At a design load of 5...
A client has a second hand Sag mill with no detail drawings of the mill pinion and girth gear.
The mill pinion has not been turned around so it has one unworn side.
To manufacture a new pinion I am advised that the pinion must be removed, taken to a the manufacturers, and accurately measured on...
