Gear Train Model | ProDynami 1248
Gear Train Model ProDynami 1248 demonstrates the mechanism of compound gears, letting students calculate gear ratio, velocity ratio and torque ratio changes caused by intermediate gears. This Gear Train Model uses steel gears with 40, 60, 80, and 100 teeth, a modulus of 2mm, and a P-ring 5x650mm drive belt on an anodised aluminium base frame. Bearings slide along T-slots for flexible set-ups, and plastic belt pulleys are available in 300mm, 320mm, and 400mm diameters. The whole equipment weighs 3-4 kg and operates using manual power.
The Gear Train Model ProDynami 1248 is designed to demonstrate the mechanism of compound gears. Through this Gear Train Model, students can inspect and calculate changes in gear ratio, velocity ratio and torque ratio caused by intermediate gears in compound gearing.
Product Overview
The Gear Train Model ProDynami 1248 uses gears of different pitch circle diameter and number of teeth, meshed together and seated on the base at the same level. Pins lock the gears in place, and the gears are adjustable. Students can perform different experiments by changing the position of the gears, achieving different velocity ratios and torque ratios. This Gear Train Model is used to demonstrate belt drives, wheel and disk drives, and gear trains. Basic terminology and relationships such as transmission ratio, direction of rotation reversal, reference circle and modulus, and the function of intermediate gears can be clearly demonstrated. A solid frame made of anodised aluminium section forms the base for the unit. Bearings for the pulleys and gears are attached to T-slots in the profile using clamping screws. These are easy to release and can be slid horizontally, making a wide range of different set-ups possible. All experiments are carried out using manual power. The size of the unit ensures the experiment is clearly visible even for larger groups of students.
