Abstract: A self-compensating hydrostatic (pressurized fluid film) linear bearing that maintains a fluid gap between a carriage and a rail when relative forces are applied. The geometric shape of the rail and mating carriage enable the bearing to have very high stiffness and load capacity without exessive detrimental carriage deformation. The carriages contain bearing grooves and lands which control and use fluid pressure to provide a very high degree of restoring force in response to changes in the fluid gap. The fluid emanating from the bearing gap is prevented from immediately leaking from the bearing carriage, and is instead routed back to the source from which it is pumped, thereby sealing the bearing carriage and simplifying the handling of the lubricating fluid. The hydrostatic bearing is particularly designed to be compact and to be bolt-for-bolt compatible with conventional linear bearings.

Abstract: The present invention is directed to an indexing tool turret assembly and method for operating the same. The indexing tool turret assembly includes a tool turret assembly rotatably supported on the machine tool, an indexing assembly for selectively rotating the tool turret assembly to a desired location. The indexing assembly includes a locking assembly to prevent rotation of the tool turret assembly during operation of either a stationary tool assembly or live tool assembly located on the tool turret assembly. A cushioning bearing assembly is provided for selectively separating the tool turret assembly from the locking mechanism during an indexing operation. The cushioning bearing assembly provides a slight lift to separate the tool turret assembly from the locking mechanism to reduce friction and other potential damages forces between these components.

Abstract: An indexing tool turret assembly is disclosed including a rotatable indexable turret tooling plate having mounted thereon stationary as well as live tooling. A single drive motor is utilized in order to perform indexing as well as to drive the live tooling. A plurality of live tools can be simultaneously mounted on the turret tooling plate and the single drive motor is selectively engageable with each of the live tools so that only one of the plurality of live tools is driven at a given time. The selective live tool drive train includes an axially movable drive shaft and bevel drive gear for selectively engaging the driven bevel gear of the desired live tool. The axially movable shaft assembly includes a mechanism for adjusting the backlash between the driving and driven bevel gears when these gears are engaged with one another. The turret assembly further includes a clutch for selectively engaging the single drive motor to index the turret tooling plate and a torque limiter provided in the indexing drive train to disengage the indexing drive in the event of a torque overload occurring during indexing.
