Gearbox Apparatus

Gearbox Apparatus The sliding mesh box, although it is still used on heavy commercial vehicles, is seldom found on modern cars, but its basic construction and operation are important from the student’s point of view as it represents the basic layout from which most modern gearboxes have been developed. Teaching objectives Measure of the angular displacement at the input and output of the gear box and comparison with the calculated values. Calculation of the efficiency for different ratios according to the torque at entry. Technical specifiations Fundamentally the gearbox consists of gear wheels of different sizes which may be engaged as required. Simple three forward ratio and reverse sliding mesh box. Pulleys fitted with protractors are attached to the input and output shafts so that the student may determine and verify velocity and torque ratios. Experiment manual Dimensions and weight 540 x 480 x 270 mm approx. Net Weight 14 kg. Essential requirements A set of masses (not supplied as standard). Optional equipment : The Gearbox can be coupled to the Overdrive and Differential  to represent a simple transmission system. The unit may be wall mounted or attached to Universal Bench Mounting Frame.
