Abstract
The utility model relates to an automatic center determining device with a rotating axis, which is provided with a bearing seat, wherein the bearing seat is provided with bearings; the bearings contact a main axis; the main axis is connected with a transmission mechanism or bears a supporting frame. The utility model is characterized in that the bearings are push conical bearings which are arranged flatly on the bearing seat; the lower end of the bearing seat is provided with the single-row conical bearings. The push conical bearings which are adopted by the technical scheme of the utility model can bear huge axial loads, and radial loads are generated under the action of a conical surface to prompt the main axis not to offset an axial lead when the main axis rotates. The single-row conical bearings which is arranged on the lower end absorb an axial jumping force to control radial offsets in consideration that axial jumpiness and the radial offsets are generated because a centrifugal action is formed when the rotating axis rotates. Meanwhile, the automatic positioning action is enhanced and the purpose that the center of the rotating axis can be determined automatically.
Description
Technical field
The utility model relates to self-centering's device of a kind of rotation, belongs to mechanical component, can be widely used in the rotary automatic plastic bottle blowing machine of various multi-position, and in the equipment such as chemical industry, pharmacy.
Background technique
In chemical industry, pharmacy and plastic article are produced, as multi-position automatic plastic bottle blowing machine, equipment all needs to rotate around shaft axis in along with spindle operation, huge thrust load (gravity is downward) and radial load (centrifugal force) are born in the vertical shaft rotation, tend to make axle to produce axial runout and radial deflection, rotation hour offset shaft axis.Prior art adopts simple thrust-bearing, only bears thrust load, can not overcome radial deflection and axial runout problem.
Summary of the invention
The purpose of this utility model is in order to overcome the shortcoming that prior art exists, and provides a kind of main shaft that makes to drive that equipment is on-stream to be born huge thrust load and absorb axial runout power, the rotational automatic centralizer of axle of control radial deflection.
The technological scheme of self-centering's device of a kind of rotation of the utility model is: a bearing support is arranged, bearing is installed in the bearing support, bearing contacts with main shaft, main shaft connects driving mechanism or carrying support, it is characterized in that described bearing is the last Plane Installation thrust conical bearing of bearing support, single row conical bearing is installed in the bearing support lower end.The technical program adopts the thrust conical bearing can bear huge thrust load, under the effect of conical surface, produce radial load, must not be offset shaft axis when impelling main shaft to do rotation, form centrifugal action when considering the running shaft rotation, produce axial runout and radial deflection, absorb axial runout power, the control radial deflection at its lower end assembling single row conical bearing, strengthen automatic positioning action simultaneously, reach running shaft self-centering purpose.
Self-centering's device of a kind of rotation of the utility model is equipped with floor clip and Thrust nut under its single row conical bearing, can connect single row conical bearing, main shaft and bearing support like this.And, seal the bearing support bottom at bearing support bottom installation end cap, and prevent that dust from entering in the bearing, prolong bearing life.Its thrust conical bearing outer end configuration dust ring.At the bearing support lower plane locating pad is arranged.Its driving mechanism that connects main shaft is a gear, under the gear brake wheel is arranged, and main shaft can be by the gear driven of power through driving mechanism.
Description of drawings
Fig. 1 is self-centering's apparatus structure schematic representation of a kind of rotation of the utility model.
