Abstract
Disclosed is a vibration exciter. Bearing installation cylindrical surfaces are arranged at two ends of a shaft. An eccentric body passes through a round hole which is formed in the eccentric body and is arranged in the middle portion of the shaft. A threaded hole is formed in the middle portion of the shaft in a radial mode. A location hole is formed in the round hole of the eccentric body in a radial mode. The eccentric body is fixed on the middle portion of the shaft through a screw. According to the vibration exciter, the vibration exciter is capable of facilitating the independent machining and processing of the shaft and the eccentric body is arranged on the shaft. Therefore, welding deformation is avoided and coaxiality of the bearing installation cylindrical surfaces which are arranged at two ends of the shaft is guaranteed. Additional load of a bearing is avoided when the vibration exciter is used. Service life of the bearing is prolonged.
Description
Technical field
The utility model relates to the vibrator that uses on a kind of vibratory roller
Background technology
The vibrator that uses on the vibratory roller is a kind of eccentric structure, produces centrifugal force when High Rotation Speed, and two ends have the bearing installation face of cylinder usually, use bearings also to be installed in the vibrating wheels.The vibrator that uses on the vibratory roller at present is welded by eccentric body and axle, two kinds of forms are arranged usually, eccentric body is welded on the bearing installation face of cylinder that the first processes first on the axle again, this moment, axle can produce welding deformation, it two is first at axle welding eccentric body reprocessing bearing the face of cylinder to be installed, this moment is because the centrifugal mechanical axis of eccentric body produces deflection deformation, no matter adopt any form, the capital is because the distortion of axle makes bearing installed surface disalignment, and the bearing that causes its two ends in the vibrator use procedure bears additional load and shortens application life of bearing.
Summary of the invention
The purpose of this utility model provides a kind of bearing installed surface axiality that improves and reaches the prolongation bearing vibrator in application life.
The purpose of this utility model is achieved in that the axle two ends have bearing that the face of cylinder is installed, eccentric body is installed in the middle part of axle by its circular hole, directly upwards there is screwed hole the axle middle part, and the Circular Aperture on the eccentric body upwards has locating hole, and eccentric body is fixed in the centre position of axle by screw.
Because the utility model adopts said structure, be beneficial to axle is processed separately and processed, and by eccentric body is assemblied on the axle, avoid welding deformation to guarantee bearings at both ends the axiality on the face of cylinder to be installed, thereby make vibrator use procedure middle (center) bearing not bear additional load, prolong the application life of bearing.
Description of drawings
Fig. 1 is the structure chart of the utility model embodiment.
Fig. 2 is the right view of Fig. 1.
1 axle, 1-1. screwed hole, 1-2 bearing are installed the face of cylinder, 2 eccentric bodies, 2-1 circular hole, 2-2 locating hole, 3 screws, 4 bearings among the figure.
The specific embodiment
Embodiment: directly upwards there is screwed hole 1-1 axle 1 middle part, axle 1 two ends have bearing that face of cylinder 1-2 is installed, wherein an end is extruded with spline 1-3, circular hole 2-1 is arranged on the eccentric body 2, Circular Aperture upwards has locating hole 2-2, eccentric body 2 is installed in the middle part of axle by its circular hole 2-1, be fixed in the centre position of axle by screw 3, and axle 1 supports and is installed in the vibrating wheels by bearing 4.
Axle 1 is part independently, can process separately and process to guarantee the axiality of bearings at both ends installation face of cylinder 1-2, eccentric block 2 is fixed on the middle part of axle 1 by circular hole 2-1 and screw 3, avoid welding deformation to bearing the face of cylinder to be installed and bring impact, thereby make vibrator use procedure middle (center) bearing 4 not bear additional load, prolonged the application life of bearing 4.
Claims (1)
1. vibrator, the axle two ends have bearing that the face of cylinder is installed, and eccentric body is installed in the middle part of axle by its circular hole, it is characterized in that: directly upwards there is screwed hole the axle middle part, Circular Aperture on the eccentric body upwards has locating hole, and eccentric body is fixed in the centre position of axle by screw.
