FIELD: machine building.SUBSTANCE: invention relates to machine building, and can be used in grinder equipped with drive of the toothed rim. The horizontal grinder is equipped with drive (8) for the toothed rim (6) containing gearbox (10) containing driven shaft (18) made with possibility of connection with motor of at least one output pinion (20), at that output pinion or each output pinion is made with possibility of engagement with toothed rim and with possibility of rotation by driven shaft, and crankcase (22). The gearbox contains at least two output pinions. The gearbox contains at least one rear down stage (26) containing rear tooth-wheel (28) for group of pinions (30), and in particular only one rear pinion (30) installed with radial mobility and engaging with each rear tooth-wheel (28) of this down stage (26).EFFECT: balance of engagement forces by assurance of free movement of the tooth-wheels.24 cl, 14 dwg |
