摘要
Automatic mechanical centering device for endless belts moving on a pair of rollers - a driving roller (RM) and a tension roller (1) - especially for an emery cloth belt (TS) moving on the cantilevered rollers (1, RM) of a belt sander (S) for wooden floors. The tension roller (1) is formed in two parts: a minor portion (3), close to a support (5) of the roller shaft (2), mounted - rotatable but not inclinable in respect of said shaft - onto an eccentric rotary sleeve (11), its part closest to said support (5) being of frustoconical shape; and a major portion (4), mounted revolving on a bush (12) coaxial to the roller shaft (2) and inclinable on a ball joint (13) but not rotatable in respect of said shaft. A unilateral contact ball constraint (15) is moreover provided between said sleeve (11) and said bush (12), and at least one spring (16) is provided to cause the inclination of said bush (12) in respect of the roller shaft (2) in the direction allowed by said constraint (15).
