Document Type and Number:
WIPO Patent Application WO2002057169
Kind Code:
A8
Abstract:
The invention relates to an arrangement for a belt drive device, which comprises two continuous drive belts, which are arranged to be operated by means of drive rollers (2), and which are arranged to travel around stretching rollers as continuous loops spaced apart, and which are arranged to be pressed by means of press rolls against the opposite surfaces of a cable or the like (3) to be drawn. In order to provide a simple structure, the drive rollers (2) are arranged to be rotated by a single power source by driving two planetary gears (8) connected in parallel and provided with angular front transmission. The rotary motion generated by the power source is arranged to be transmitted in the same direction to primary axles (9) of both planetary gears (8) provided with angular front transmission in order to rotate secondary axles (10) and the drive rollers (2) connected thereto in opposite directions.
