Abstract
The utility model discloses a grinding wheel spindle. The grinding wheel spindle comprises a grinding wheel spindle body, wherein a grinding wheel spindle sleeve is installed on the grinding wheel spindle; a front end cover and a rear end cover are installed on the grinding wheel spindle body respectively, and the grinding wheel spindle sleeve is connected with the front end cover and the rear end cover; a centripetal angular contact bearing and a double-row cylindrical roller bearing are installed between the grinding wheel spindle body and the grinding wheel spindle sleeve respectively. The grinding wheel spindle is high in rigidity, good in sealing performance, and capable of reducing jitter at the time of operation, so that the service life of the grinding wheel spindle is greatly prolonged.
Description
Technical field
The utility model relates to a kind of grinding wheel spindle.
Background technology
Grinding wheel spindle in abrasive machine can drive emery wheel to process.When processing roll rigidity is large or diameter is larger, the high speed rotating of emery wheel can drive the axial float of grinding wheel spindle.When increasing energy consumption, also can cause the damage of grinding wheel spindle, shorten the service life of grinding wheel spindle.Emery wheel adds man-hour, can on grinding wheel spindle, use oil lubrication, but its sealing of grinding wheel spindle apply oil of using is in the market undesirable.
Summary of the invention
For addressing the above problem, the purpose of this utility model is to provide a kind of grinding wheel spindle, and its rigidity is strong, good airproof performance, the play in the time of can reducing grinding wheel spindle running, thereby the service life of greatly having improved grinding wheel spindle.
The utility model is the object that reaches above-mentioned, and the utility model adopts following technical scheme:
A grinding wheel spindle, comprises grinding wheel spindle, and grinding wheel spindle axle sleeve is installed on described grinding wheel spindle, is separately installed with drive end bearing bracket and rear end cap on described grinding wheel spindle, and described grinding wheel spindle axle sleeve is connected with drive end bearing bracket, rear end cap respectively; Between described grinding wheel spindle and grinding wheel spindle axle sleeve, be separately installed with centripetal angular contact bearing and Biserial cylindrical roller bearing.
Described drive end bearing bracket is spelled jack panel by the first pre-load nut, first successively and is connected with grinding wheel spindle.
Described rear end cap is spelled jack panel by the second pre-load nut, second successively and is connected with grinding wheel spindle.
First minute compression ring is installed on described drive end bearing bracket, second minute compression ring is installed on described rear end cap.
On described grinding wheel spindle, end ring is installed, and described end ring contacts with Biserial cylindrical roller bearing.
Between described grinding wheel spindle axle sleeve and rear end cap, sealing ring is installed.
The beneficial effects of the utility model are: the utility model provides a kind of grinding wheel spindle, and its rigidity is strong, good airproof performance, the play in the time of can reducing grinding wheel spindle running, thereby the service life of greatly having improved grinding wheel spindle.
Accompanying drawing explanation
Fig. 1 is the structural representation of utility model.
