    摘要: A rotary drive apparatus comprises a housing including an intermediate transmission portion, an input shaft portion connected to one end of the intermediate transmission portion and extending outwardly therefrom in a first direction and an output shaft portion connected to the opposite end of the intermediate transmission portion and extending outwardly therefrom in a second opposite direction. The intermediate transmission portion is provided with an exhaust port for the exhaust of air which is directed under pressure to an air motor which is carried eccentrically in a rotatable mounting in the input shaft portion of the housing. The air motor includes a drive pulley on its drive shaft which is connected through a belt to a driven pulley carried on a output shaft which is rotatably supported in the output shaft portion of the housing and which includes an outer drive end which is connected to a drive element, for example, a grind stone. Compressed air which is circulated through the drive motor is discharged through the exhaust port of the intermediate transmission portion of the housing. The tension on the drive belt extending between the input pulley on the air motor drive shaft and the output pulley carried on the output shaft may be adjusted by rotating the mounting for the air motor so as to vary the spacing between the input and the output shafts and thereby to adjust the tension on the belt. After this tension is adjusted the mounting for the air motor is clamped into position.

    摘要: The air motor has substantially the size of a standard fountain pen and includes an extruded outer cylindrical casing formed with a circular cross-section eccentric inner surface which has annular grooves in its forward part and a smooth surface, substantially coincident with the bases of the grooves, in its rear part. The grooves constitute air supply and exhaust passages, a retainer groove and a pin groove. A front retainer closes the forward end of the casing and has a tongue projecting into the retainer groove to maintain a predetermined angular orientation in the casing, and a rear retainer is seated against the ribs defining the grooves in the forward portion of the casing and has a tongue projecting into the retainer groove to maintain a relative angular orientation with respect to the front retainer. A motor cylinder is mounted in the casing between the two retainers and has air supply and exhaust ports communicating with the air supply and exhaust passages, respectively. A vane type rotor is rotatably supported in the two retainers, through bearings, and is eccentric to the motor cylinder. The forward end of the rotor is formed with a shaft by means of which a grinder or another tool can be secured to the rotor. The portion of the casing rearwardly of the rear retainer constitutes an air supply and control chamber in which there is an air filter means, and the air passing through the filter means flows through supply passages in the rear retainer into the air supply passage. A connection is provided at the rear of the casing for connecting the air motor to a source of air under pressure, and a manually operable grip threaded on this connection controls the supply of air under pressure to the supply and control chamber. In a modification of the air motor, the exhaust air flows rearwardly along the exterior surface of the motor cylinder and through sound absorbing means to exhaust ports leading to the atmosphere or to an exhaust line.
