Labelling in accompanying drawing: air intake duct 1, annular air channel 2, cooling water annulus 3, cooling water channel entrance 4, reducer 5, torus knot chute 6, cooling water channel outlet 7, air vent 8.
Detailed description of the invention
Below in conjunction with the accompanying drawings preferred embodiment of the present utility model is described in detail, so that advantage of the present utility model and feature can be easier to be readily appreciated by one skilled in the art, thus protection domain of the present utility model is made apparent clear and definite defining.
Refer to accompanying drawing 1 ~ 3, the air-flotation electric spindle of a kind of thrust bearing of the present utility model, on the bearing block of this air-flotation electric spindle, it is provided with torus knot chute 6, cooling water channel entrance 4, cooling water channel outlet 7, cooling water annulus 3, air intake duct 1, reducer 5, described torus knot chute 6 is rounded, is placed in the end face of bearing block；Described cooling water channel entrance 4, cooling water channel outlet 7 is with circular torus knot chute 6 centrosymmetry, and lives apart in the both sides of torus knot chute 6；Described cooling water annulus 3 is placed in the inner over glaze mouth edge of bearing block, its passway connection cooling water channel entrance 4；The inlet end of described air intake duct 1 and cooling water channel entrance 4 are at same end face, and this air intake duct 1 connects annular air channel 2, and described annular air channel 2 is placed in the outside of water annulus 3；Described reducer 5 is arranged on the outer face of bearing block, its gas port connection air intake duct 1, annular air channel 2.Described air intake duct 1 first extends axially inwardly, then 90 degree of turnings, pivoting point direction, until at the air flue of connection reducer 5, the air flue straight line connection annular air channel 2 of reducer 5.On the bearing block of described air-flotation electric spindle, being additionally provided with air vent 8, this air vent 8 first extends axially inwardly, then 90 degree of turnings, pivoting point direction, until with axle center pipeline communication.The air-flotation electric spindle of thrust bearing typically works in water smoke, so the air-flotation electric spindle interior waterproof design of thrust bearing is particularly important, because sealing during spindle processing when blowing and having moisture, and water-spraying control etc., as waterproof effect is bad, cause the air-flotation electric spindle inner inlet of thrust bearing, easily cause bearing grease to go bad burn bearing or cause coil breakdown, so that the air-flotation electric spindle of thrust bearing damages.This utility model increases torus knot chute and cooling water channel, air intake duct, gas off-take at the air-flotation electric spindle of thrust bearing, makes the machining accuracy of air-flotation electric spindle improve, improves the service life of whole thrust bearing simultaneously, it is to avoid whole main shaft damages.
