Description
This is the gearbox of the SM 1A Meccano Motor Chassis. You can find the leaflet here :
http://meccrl.free.fr/sml/
The animation system in VM manages only the simple rotations and translations, and the electric motor is bigger that the one in the leaflet ! So I have built only the gearbox, with 4 forward speeds and the reverse. You drive it with the three layshafts controls which names are built with a color name and the name in the leaflet.
Menu : View : Toolbars and Docking Windows : Motion, adjust the general speed and the MOTOR speed. Then select the unit controls in the rigthmost unit combo box :
-BLUE_layshaft_51 : speed 3, neutral, speed 4
-WHITE_layshaft_61 : speed 1, neutral, speed 2
-RED_layshaft_75 : forward reverse. CAUTION ! You can only use it when the others layshafts are on the Neutral position. Or you destroy the gearbox of a Bentley ! Ouch !
The model is given in neutral position. Use the numkeys + and – to drive it.
The speed ratios are : 0,2 - 0,58 - 1 – 1,73
Now if somebody wants build the entire model around this one, I say to him : good luck !
