Abstract
The utility model relates to a hybrid bearing which comprises a bearing main body as well as a static pressure oil chamber, a transitional oil chamber and a dynamic pressure oil chamber sequentially arranged on the inner wall of the bearing main body from deep to shallow, wherein the transitional oil chamber is connected between the static pressure oil chamber and the dynamic pressure oil chamber and is arranged in involute. The static pressure oil chamber and the dynamic pressure oil chamber are arranged to enhance the bearing capacity of the hybrid bearing. The transitional oil chamber is connected with the static pressure oil chamber and the dynamic pressure oil chamber, so that the static pressure oil chamber and the dynamic pressure oil chamber are smoothly connected. In addition, the transitional oil chamber is arranged in involute, so that the dynamic pressure bearing capacity and rigidity of the hybrid bearing are enhanced according to hydromechanical property of hydraulic oil.
Description
Technical field
The utility model relates to a kind of bearing, is specifically related to a kind of dynamic and hydrostatic bearing.
Background technique
At present, the bearing that is used for grinding wheel spindle of grinder is mainly selected hydraulic bearing or hydrostatic bearing for use, the bearing of part high-precision grinder main shaft then adopts the sound bearing, and the oil pocket structural type of these dynamic and hydrostatic bearings is with the laying of staggering in the axial direction of dynamic pressure cavity and static pressure chamber, so, before entering the normal operation operating mode, utilize the static pressure in static pressure chamber to be used for carrying external load; When entering the normal operation operating mode, close the pressure oil in static pressure chamber, carry external load by the kinetic pressure of dynamic pressure cavity.The bearing of this structural type is the simple combination mode of dynamic pressure and static pressure, and is not compound on function, complex structure and bearing capacity deficiency.
Given this, the dynamic and hydrostatic bearing of some improved types appears in industry, and dynamic pressure cavity and static pressure chamber are arranged direct connection, and then, its bearing capacity is defectiveness still.
