General design

The mechanical variable speed chain gear-boxes are one of the systems of infinitely variable speed gears assuming a dominant position in the driving technique for the transmission of little and mean outputs.

Owing to their properties, such as:

• the sufficiently large control range
• the suitable control characteristic
• the minimum drop of speed when loaded
• the minimum claims for maintenance
• the simple manipulation

the mechanical variable speed gear-boxes with plate-link chains range with the most demanded types.
