Abstract: A novel turbine motor spindle assembly for a spindle-mounted pneumatic tool, especially in a live tool environment is described. The novel turbine motor spindle assembly includes a manifold with a front end and a rear end. The manifold includes an air intake passage for receiving pressurized air. The pressurized air is directed axially through a drive shaft rotatably coupled to the front end. The pressurized air drives a turbine motor assembly and a drive shaft. The drive shaft is mounted inside a housing is self-lubricating. The turbine motor assembly includes tangential openings for expelling exhaust air therefrom. The turbine motor housing is mechanically coupled to the front end of the manifold with an exhaust air passage for directing exhaust air from the one or more tangential openings out through the rear end of the manifold.

Abstract: A novel mounting assembly used with an air spindle is described. The mounting assembly includes an insertable top portion for inserting into a mounting collar and to be rotatable therein, the insertable top portion formed with an upper disk shape with a first diameter and a lower disk shape with a second diameter and adjacent to the upper disk shape, an outer circumference of the upper disk shape having a groove formed therein, and the upper disk shape and the lower disk shape having a passage axially formed therethrough perpendicular to the groove. The mounting assembly further includes a sleeve disposed below the insertable top portion, the sleeve defining an opening with a sidewall which is perpendicular to the insertable top portion, the opening sized to hold a spindle, a port inside a wall of the sleeve defining the opening providing fluid communications with the passage of the insertable top portion.

Abstract: A high torque dual speed turbine rotor for a lightweight hand held tool for grinding and polishing or for use with a spindle mounted pneumatic machine. The high torque dual speed turbine rotor includes a two-piece shaft with flow control screw disposed within the shaft. The shaft includes a first set of hollow openings, at a first position from one end of the shaft, in fluid communications with a first annular chamber of a rotor. There is also a second set of hollow opening, at a second position from the one end of the shaft, in fluid communications with a second annular chamber of the rotor. The flow control screw moves inside a threaded axial bore of the shaft from an open position inside the axial bore to the closed position corresponding to the second set of hollow openings.

Abstract: Described is a novel spindle mounting assembly for use with a computer numeric controlled (CNC) machine, such as a drill tap machine. In one example an auto changer spindle mounting assembly includes a collar with a gas inlet. The collar defines a collar opening therethrough to create a passage between the first side of the collar with the second side of the collar. The collar further includes a passage in fluid communication between the gas inlet and through a nipple to the collar opening. The mounting assembly includes a manifold body with a gas outlet adapted to mate with the gas inlet of the collar, the manifold body defined a passage in fluid communications between, the gas outlet and a manifold body inlet. Also included is at least one extension bar, adapted to mechanically fasten to the manifold body to a computer controlled machine.

Abstract: An apparatus and method for machining is provided. A mounting assembly for use with a spindle, a CNC machine, an auto changer device and an air supply line, can include a mounting collar and a mounting block. The mounting collar can have a collar body and a collar arm, where the collar body defines a collar opening and one or more grooves circumscribing the collar opening, where the one or more grooves each have a sealing element positioned therein, and wherein the collar arm has a collar inlet, a collar outlet and a collar channel to provide fluid communication between the collar inlet and the collar outlet. The mounting block can be connected to the CNC machine and can have a block inlet connected to the air supply line, a block outlet, and a block channel to provide fluid communication between the block inlet and the block outlet.

Abstract: A rotary device having an inlet adapter for connecting the device to a pressurized fluid source, a turbine rotor, and an input passage. The input passage provides fluid communication between the input adapter and the turbine rotor, has a first end proximate the inlet adapter and an opening downstream from the first end, and has a generally constant cross sectional area between the first end and the opening.

Abstract: A high torque turbine rotor for a lightweight hand held tool for grinding and polishing having a rotor that includes two separate high pressure air chambers separated by a common housing wall, each air chamber having peripheral air expelling nozzles in a tangential direction to the rotor periphery. The rotor housing is lightweight and increases torque without generally increasing the overall size and weight of the tool housing.

Abstract: A spindle apparatus operative by a fluid powered reaction turbine-type motor and having a handle portion, a head portion and a device for attaching a desired tool thereto. The handle portion includes a channel for directing the flow of a received fluid. The head portion includes the reaction turbine-type motor which is coupled to an outlet of the channel so as to receive the fluid therefrom. The head portion further includes a rotatable shaft which is coupled to the reaction turbine-type motor and to the attaching device. Upon receiving fluid from the handle portion, the reaction turbine-type motor rotates, thereby causing the shaft and the tool to rotate.

Abstract: A braking mechanism for a rotary apparatus having a housing adapted to receive a pressurized fluid and a rotor rotatably mounted in the housing. The braking mechanism enables the rotor to rotate in the housing in response to the receipt of the pressurized fluid and inhibits the rotor from rotating in the absence of the receipt of the pressurized fluid.
