Independent tensioning wheel waterproof structure of multi-rope group sawing machine

Abstract

The utility model provides an independent tensioning wheel waterproof structure of a multi-rope group sawing machine, a main body comprises a bearing, a tensioning wheel flange, a tensioning wheel, a bearing shell, a bearing core shaft, a flange cover and a tensioning wheel bracket, dynamic seals are arranged between the tensioning wheel flange and an annular waterproof baffle and between the flange cover and the bearing shell, and the dynamic seals adopt labyrinth seal structures. And an annular water guide groove and a straight drainage groove are arranged. According to the waterproof structure for the independent tensioning wheel of the multi-rope group sawing machine, at least one group of labyrinth sealing structures with the annular water guide grooves and the straight drainage grooves is arranged, and stone slurry water entering the labyrinth sealing structures is guided by the annular water guide grooves and is drained through the straight drainage grooves. According to the waterproof structure for the independent tensioning wheel of the multi-rope group sawing machine, stone slurry water entering the independent tensioning wheel can be reduced, and the service life of the bearing is prolonged.
