Abstract
The utility model discloses a bearing support structure for a rotating shaft of a position transmitter. The bearing support structure comprises a shell body and the rotating shaft of the position transmitter, wherein a first rolling bearing for supporting the rotating shaft is embedded into one side of the shell body; a bearing seat is arranged on the other side of the shell body; a second rolling bearing which is concentric with the first rolling bearing and supports the rotating shaft is embedded into the bearing seat; the rotating shaft is provided with an elastic retaining ring for a shaft which is connected with the inner circle of the second rolling bearing. The first rolling bearing and the second rolling bearing are oil-containing deep groove ball bearings in the same model number. The bearing support structure for the rotating shaft of the position transmitter adopts two same rolling bearings; as the dynamic resistance of the rolling bearings or the oil-containing rolling bearings is low, the problems that the cylindrical shell body of a powder metallurgy oil-containing shaft sleeve position transmitter has reliable sealing performance, rusting and blocking are thoroughly solved. The bearing support structure for the rotating shaft of the position transmitter has the outstanding advantages that the position transmitter reliability is improved, the service life of an executing mechanism is prolonged, and the maintenance cost is reduced.
Description
Technical field
The utility model belongs to electric actuator, particularly relates to a kind of bearing support structure of electric pneumatic converter rotating shaft.
Background technique
Electric pneumatic converter is one of vitals of electric actuator, its fundamental composition comprises housing, rotating shaft, gear, limit switch, phase-splitting capacitor, cam pack, conductive plastic potentiometer, socket etc., between rotating shaft and housing, oiliness shaft lining for powder metallurgy is set.
To there is contained grease volatilization in the long-time use under compared with the condition such as high ambient temperature, dust of above-mentioned oiliness shaft lining for powder metallurgy, phenomenon dries up, cause rotating shaft and oiliness shaft lining for powder metallurgy surface of contact to get rusty, glue together even stuck, when serious, will cause shaft gear to damage.Oiliness shaft lining for powder metallurgy is also often in being difficult for the position of oiling in electric pneumatic converter, and therefore grease volatilization, withered phenomenon can not be avoided.
The above-mentioned phenomenon of oiliness shaft lining for powder metallurgy will directly cause the serious consequence that actuator is uncontrolled, consequently damage valve.
Summary of the invention
The utility model is that grease volatilization, the withered technical problem that causes serious consequence appear in the oiliness shaft lining for powder metallurgy in order to solve between existing electric pneumatic converter rotating shaft and housing, and a kind of bearing support structure of electric pneumatic converter rotating shaft is provided.
The utility model is taked following technological scheme for achieving the above object: a kind of bearing support structure of electric pneumatic converter rotating shaft, comprise housing and the rotating shaft of electric pneumatic converter, feature is, described housing one side inserting slot is provided with the first rolling bearing of supporting revolving shaft, housing opposite side is provided with bearing support, described bearing support is installed with the second rolling bearing of the supporting revolving shaft concentric with the first rolling bearing, and rotating shaft is provided with the circlip for shaft engaging with the second rolling bearing inner ring.
The utility model can also be taked following technical measures:
The oil-containing deep groove ball bearing that described the first and second rolling bearings are same model.
The beneficial effects of the utility model and advantage are: the bearing support structure of this electric pneumatic converter rotating shaft adopts two identical rolling bearings, due to rolling bearing or preferably its dynamic resistance of oil-containing rolling bearing is little, thoroughly solve existing oiliness shaft lining for powder metallurgy electric pneumatic converter cylindrical housings and there is reliable sealability, got rusty, stuck problem.The utlity model has the outstanding advantages that improves electric pneumatic converter reliability, extends actuator's working life and reduction maintenance cost.
