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

A kind of dynamic and hydrostatic bearing

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.

The model utility content

At the problem that prior art exists, the purpose of this utility model is to provide a kind of dynamic and hydrostatic bearing, the big and good rigidly of its bearing capacity.

A kind of dynamic and hydrostatic bearing that the utility model provides, it comprises that bearing main body reaches successively by being deep to shallow static pressure oil pocket, transition oil pocket and the dynamic pressure oil pocket that is arranged at the inwall of described bearing main body, wherein, described transition oil pocket connects described static pressure oil pocket and described dynamic pressure oil pocket and is the involute setting.

Based on disclosing of above technological scheme, the utility model possesses following beneficial effect:

A kind of dynamic and hydrostatic bearing that the utility model provides, it comprises that bearing main body reaches successively by being deep to shallow static pressure oil pocket, transition oil pocket and the dynamic pressure oil pocket that is arranged at the inwall of described bearing main body, wherein, described transition oil pocket connects described static pressure oil pocket and described dynamic pressure oil pocket and is the involute setting; The setting of described static pressure oil pocket and described dynamic pressure oil pocket is to promote the bearing capacity of described dynamic and hydrostatic bearing, described transition oil pocket connects described static pressure oil pocket and the setting of described dynamic pressure oil pocket, so that described static pressure oil pocket and the smooth connection of described dynamic pressure oil pocket, in addition, described transition oil pocket is the involute setting, according to the hydrodynamic performance setting of hydraulic oil, to promote dynamic pressure bearing capacity and the rigidity of described dynamic and hydrostatic bearing.
