Sliding system for a wraparound transmission

A sliding rail for a wraparound element of a wraparound transmission for reducing vibrations and undulations of the wraparound transmission, the sliding rail comprising:

• a sliding channel with an inner sliding face and an opposing outer sliding face, wherein, the sliding channel defines a running direction for the wraparound element,
• the wraparound element having, in the running direction, a plurality of deflecting axes oriented transversely with respect to the running direction and parallel to the inner and outer sliding faces, and the wraparound element having a height oriented transversely with respect to the deflecting axes, and
• wherein the sliding channel is divided in the running direction into an entry section, a main section and an exit section, the sliding channel having a setpoint height adapted to the height of the wraparound element,
• wherein an operating temperature of the inner and outer sliding faces, the main section has a first section height equal to the setpoint height, and, at a lower temperature of the inner and outer sliding faces, the first section height is lower than the setpoint height.
