Abstract
A static pressure air bearing for an impeller dynamic balancing machine comprises an air bearing body, and is characterized in that an air chamber is arranged in the air bearing body, and a plurality of nozzles are arranged at the upper and lower parts of the air bearing body in a circular way and communicated with the air chamber. A connecting plate is fixedly arranged at the bottom of the air bearing body. The static pressure air bearing for the impeller dynamic balancing machine improves measuring precision, removes the combination error between a central spindle and the impeller and the rotation error of a high-speed supporting bearing, and improves working efficiency.
Description
Technical field
The utility model belongs to static-pressure air bearing, impeller dynamic balancing machine technical field, is specifically related to a static-pressure air bearing that is used for the impeller dynamic balancing machine.
Technical background
Static-pressure air bearing is one of common form of gas bearing, the static pressure air-bearing lubricating bearings is because advantages such as running speed height, rotating accuracy height, lubricated clean environmental protection are widely used in fields such as Precision Machining industry, low temperature compression industry, food industry, medical and health industry, nuclear industry, Aero-Space gradually.
On traditional impeller dynamic balancing machine, at first select the mandrel that matches with impeller when doing transient equilibrium, and then impeller is contained in is placed on the enterprising action balance of dynamic balancing machine on the mandrel.Major defect is 1, efficient is low.2, precision is low.
The utility model content
For addressing the above problem, the utility model provides a kind of static-pressure air bearing that is used for the impeller dynamic balancing machine.
The technical scheme that adopts is:
A kind of static-pressure air bearing that is used for the impeller dynamic balancing machine comprises the air-bearing main body, is characterized in being provided with air chamber in the air-bearing main body, and the upper and lower of air-bearing main body is equipped with a plurality of nozzles respectively, and a plurality of nozzle all is connected with air chamber.The bottom of air-bearing main body is installed with web joint.
Replace the tapering mandrel with static-pressure air bearing, utilize the self-centering principle of air-bearing, automatic capturing.Allow impeller be in suspended state, the periphery drives by pressurized air simultaneously.
The working method of the utility model static-pressure air bearing is: when balance begins, and the air-bearing stuffiness, manually put into impeller on the air-bearing and (between air-bearing and the impeller certain clearance is arranged) this moment.The balance start button is pressed, the air-bearing ventilation, and impeller is in suspended state.This moment, the peripheral driver source of the gas was opened, the impeller rotation, and equilibrator enters duty.
The utility model has following beneficial effect:
(1) improves measuring accuracy.
(2) reject the mismatch error of mandrel and impeller, rejected the rotation error of high speed spring bearing.
(3) increase work efficiency.
Description of drawings
Fig. 1 is the structural representation of static-pressure air bearing in the utility model.
Embodiment:
