SKU: AG-014

Epicyclic Gear Unit (2 elements)

This unit is assembled in an anodized aluminum profiles structure, with a steel panel painted in epoxy paint.

It is a bench-top unit supported by four legs. Besides, it is provided with four brackets to be suspended in the wall, which allows the experiments with weights to be carried out more easily.

This unit is mainly composed of:

2 Coupled epicyclic gears sets, formed by:

Sun gears.

Satellite gears set.

Common support of the satellites.

External ring.

2 Graduated discs located at the input and output shafts.

Different mechanical pins that simulate the pilot valves used to brake the different planetary components.

The shafts of the unit are made in stainless steel. The discs and gears are made in aluminium to facilitate the experiments.

The pinions are mounted on ball bearings to reduce frictional losses. They are made in aluminium, so the inertia will be less and the results of the experiments will be improved.

The MTE2 unit provides three forward speeds.

In order to carry out some of the practices with MTE2 unit, 2 set of weights “B type” are required. (See required accessories).

Manuals: This unit is supplied with the following manuals: Required services, Assembly and Installation, Starting-up, Security, Maintenance and Practices manual. 

Dimensions (approx.): 360 x 260 x 300 mm.  

Weight: 24 Kg.
