Description and Specification for Lab Tenders
Astra Scientific Working Model of Gear Box.
The Gear box with engine cutaway model is carefully sectioned for
training purposes, professionally painted with different colours to
better differentiate the various parts, cross-sections, lubricating
circuits, fuel system, cooling system etc. Many parts have been
chromium-plated and galvanized for a longer life.
The gearbox provides a selection of gears for different driving
conditions: standing start, climbing a hill, or cruising on level
surfaces. The lower the gear, the slower the road wheels turn in
relation to the engine speed.
The engine drives the input shaft, which drives the lay shaft. The lay
shaft rotates the gears on the main shaft, but these rotate freely until
they are locked by means of the synchromesh device, which is splined to
the shaft.
