Abstract
The invention relates to a transmission apparatus in connection with a pulling equipment intended for moving especially a cable or a corresponding product, the transmission apparatus comprising a shaft that is operated by a motor ( ) and that is connected to an output shaft ( ) of the transmission apparatus by means of cog wheels ( ). The output shaft ( ) is connected to means ( ) that are in contact with the cable. The cog wheels ( ) are arranged to form a circle extending from the motor-driven shaft to the output shaft (16) and correspondingly from the output shaft ( ) to the motor-driven shaft. In order to provide clearance-free operation, the cog wheels ( ) are helical gearwheels, and one cog wheel shaft is arranged to be moved in its longitudinal direction when the rotation of the output shaft ( ) is being decelerated.
