摘要： An expandable handheld pneumatic belt grinder includes a body, an expansion component and an operation component. The body has a receiving space, a pneumatic motor, and a rotating wheel driven by the pneumatic motor. The expansion component has an expansion pipe and an expansion rod which are connected. The expansion rod is coupled to the receiving space. The operation component has a support rod with one end carrying a driven wheel and the other end coupled to the receiving space or expansion pipe. A grinding belt fits around the driven wheel and rotating wheel collectively. A user changes the distance between the rotating wheel and driven wheel by choosing between two options: coupling the support rod of operation component and the receiving space; and coupling the expansion rod of expansion component and the receiving space, and then coupling the support rod of operation component and the expansion pipe.

摘要： A sander capable of correcting airflow amount comprises a body and a correction valve. The body includes an air intake passage to receive pressurized air, a drive motor driven by the pressurized air to rotate at a rotational speed including a preset range and an excessive range, and a regulation valve located on the air intake passage to adjust the rotational speed of the drive motor in the preset range. The correction valve includes an adjustment portion operable in an adjustment displacement and a mask wall movable by the adjustment portion to block the air intake passage. The adjustment portion determines the flow amount of the pressurized air passing through the correction valve according to the adjustment displacement thereof to confine the rotational speed of the drive motor from the excessive range to the preset range, thereby controls the rotational speed of the drive motor in the preset range.

摘要： A spin index fixture has a housing which is provided with an air inlet shaft for permitting pressurized air to enter the housing and to propagate through grooves disposed along the outer surface of the sleeve. The air then enters into a clearance volume between the housing and the spindle and serves as an air bearing. The spindle is further provided with impelling recesses disposed circumferentially along the outside surface of the spindle at an axial location that is in alignment with the pressurized air inlets. The force of the air against the recesses rotates the spindle about its axis when the pressurized air supply contacts the recesses.

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.
