Geared System Apparatus | ProDynami – 1346
The Geared System Apparatus ProDynami – 1346 investigates the dynamic behavior of 1, 2, and 3 stage spur gear units using 4 shafts. This Geared System Apparatus is driven by a cable drum and weight set via a removable crank, with a total transmission ratio of i = 64:1. It features inductive speed sensors, a transparent protective cover, and a hand brake for gentle braking. Optional flywheel masses and a chart recorder support angular acceleration and efficiency studies.
The Geared System Apparatus ProDynami – 1346 consists of a 3-stage spur gear unit with 4 shafts, allowing one and two stage gear units to also be realized. This Geared System Apparatus drives gears using a cable drum and a variable set of weights lifted via a removable crank. Each shaft can be equipped with an additional flywheel mass to increase angular inertia.
Product Overview
This unit consists of a 3-stage spur gear unit with 4 shafts. One and two stage gear units can thus also be realized. Each shaft can be equipped with an additional flywheel mass to increase the angular inertia. The gears are driven using a cable drum and a variable set of weights that are lifted using a removable crank. Unwinding is prevented by a safety catch; a clamping roller free wheeling hub prevents undesired coiling of the cable. The weight is arrested by a receptacle with an impact attenuating insert.
A hand brake facilitates gentle braking. The transparent protective cover prevents unintentional contact with the rotating parts. All four shafts are fitted with inductive sensors for measuring the speed. A chart is used to record speed-time diagrams from which the angular acceleration can be read on this Geared System Apparatus.

Construction and Design
The Geared System Apparatus ProDynami – 1346 consists of a 3-stage spur gear unit with 4 shafts, allowing 1 and 2 stage gear units to also be realized. Gear width is 16mm at modulus 2, giving a transmission ratio of i = 4:1 per stage and i = 64:1 total. Each shaft can be equipped with an additional flywheel mass to increase angular inertia. The gears are driven using a cable drum and a variable set of weights, lifted using a removable crank, with a fall height of up to 0.65m. A safety catch prevents unwinding, and a clamping roller free wheeling hub prevents undesired coiling of the cable. The weight is arrested by a receptacle with an impact attenuating insert. A hand brake facilitates gentle braking. A transparent protective cover prevents unintentional contact with the rotating parts. All four shafts are mounted in ball bearings and fitted with inductive sensors for measuring speed, supported by an optional chart recorder with a chart width of 100mm, paper feed of 7200mm/h, and speed range of 0 to 2000rpm. The apparatus is built on a sturdy steel tube support.
Scope of Delivery
