The planet gears are mounted on a planet carrier and engage positively in an internally toothed ring gear. Torque and power are distributed among several planet gears. The planetary gear is a special type of gear drive, in which the multiple planet gears revolve around a centrally arranged sun gear. Sun gear, planet carrier and ring gear may either be driving, driven or fixed. The trainer consists of two planet gear sets, each with three planet gears. The ring gear of the first stage is coupled to the planet carrier of the second stage. By fixing individual gears, it is possible to configure a total of four different transmission ratios. Planetary gears are used in automotive construction and shipbuilding, as well as for stationary use in turbines and general mechanical engineering. Unit allows the investigation of the dynamic behaviour of a two-stage planetary gear. The gear is accelerated via a cable drum and a variable set of weights. The set of weights is raised via a crank.

Absorption refrigeration systems operate using thermal energy. This basic principle is demonstrated in the experimental unit with the example of an ammonia-water solution with the ammonia acting as refrigerant. They use the principle of liquids evaporating already at low temperatures when pressure is reduced. In the evaporator the liquid ammonia evaporates and withdraws heat from the environment. To keep the evaporation pressure low, the ammonia steam in the absorber is absorbed by the water. For this purpose, the high concentration ammonia solution is heated in a generator until the ammonia evaporates again. In the final step, the ammonia steam is cooled in the condenser to the base level, condenses and is returned to the evaporator. The low concentration ammonia solution flows back to the absorber. To maintain the pressure differences in the system, hydrogen is used as an auxiliary gas. In the next step, ammonia is permanently removed from the high concentration ammonia solution to prevent the absorption process from being halted.

The medium for the experiment is fed through a gap. The gap between the two elements was selected so that the transfer of heat due to convection can be ignored. It comprises a cylindrical heat exchanger with a heated inner cylinder made of aluminium and a water-cooled jacket. Due to the low temperatures and the polished surfaces, the radiation portion of the heat transfer is also negligible. This experimental unit enables experiments to be performed on steady-state thermal conduction in liquid and gaseous materials. Temperature sensors measure the temperature difference.

The equipment may be mounted vertically for demonstration purposes, or flat on the bench for experimental use. The crank length is adjustable, and the connecting rod length can be varied. Crankshaft rotation is measured by a rotating protractor scale and piston displacement is shown on a sliding scale. The apparatus shows the relationship between crank shaft rotation and piston displacement, for a fixed "cylinder".
This equipment is part of a range designed to both demonstrate and experimentally confirm basic engineering principles. Setting up time is minimal, and all measurements are made with the simplest possible instrumentation, so that the student involvement is purely with the engineering principles being taught. Great care has been given to each item so as to provide wide experimental scope without unduly complicating or compromising the design. Each piece of apparatus is self-contained and compact.
