Abstract
The utility model relates to the field of mechanical equipment and provides a high-speed rotating shafting vibration elimination device of a cantilever shaft structure. The high-speed rotating shafting vibration elimination device comprises two supporting bearings, a shaft and a cantilever object, as well as an auxiliary shaft and an auxiliary bearing, wherein the shaft is supported by the two supporting bearings; the cantilever object strides across the shaft of the supporting bearing at one end to be hung at the tail end; the center of the shaft at the tail end of the cantilever object is additionally provided with the auxiliary shaft and is concentric with the shaft and the cantilever object; and the auxiliary shaft and the auxiliary bearing are installed at the tail end of the cantilever object. The high-speed rotating shafting vibration elimination device is convenient in operation and can solve the vibration problem of the high-speed rotating shafting of the cantilever shaft structure.
Description
Technical field
The utility model relates to the machinery field, and particularly the high-speed rotating shaft of cantilevered axle structure is a vibration cancelling arrangement.
Background technique
The high-speed rotating shaft system of cantilevered axle structure, regular appearance vibration exceeding the standard can't satisfy the needs of normal operation, and on-the-spot general several ways are centering centerings, do dynamic balancing, reduce methods such as bearing radial gap, but sometimes various ways are used up, still can't be solved vibration problem.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and the high-speed rotating shaft that a kind of cantilevered axle structure is provided is a vibration cancelling arrangement.
The technical solution of the utility model is as follows:
A kind of high-speed rotating shaft of cantilevered axle structure is a vibration cancelling arrangement, comprise two spring bearings, axle, the cantilever thing, also comprise auxiliary axis, auxiliary bearing, described axle is supported by two spring bearings, described cantilever thing strides across a described end spring bearing and hangs at described the tip of the axis, increase auxiliary axis at described cantilever thing terminal shaft center, and with described axle, the cantilever thing is concentric, described auxiliary axis, auxiliary bearing is installed on described cantilever thing end, main of described auxiliary bearing plays the weakening effect, do not bear excessive load, so the diameter of axle, bearing size is selected other diameter of axle relatively, spring bearing is less.
The beneficial effects of the utility model are:
Easy to operate, and can solve the vibration problem of the high-speed rotating shaft system of cantilevered axle structure.
Description of drawings
Figure is the utility model structural representation.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
As shown in the figure, the utility model comprises spring bearing 1, spring bearing 3, axle 2, cantilever thing 4, auxiliary axis 6, auxiliary bearing 5.Axle 2 is supported by spring bearing 1 and spring bearing 3, the cantilever structure axle is that cantilever thing 4 strides across the end of spring bearing 3 at axle 2, reason vibrations such as often big owing to initial weight, axle is that rotating speed is higher, cantilever centre distance spring bearing 3 is far away are bigger, if dynamic balancing, equipment are installed every data all in index, still because vibration can't run well, can reduce vibration by increase auxiliary axis 6, auxiliary bearing 5.
The above, it only is preferred embodiment of the present utility model, be not that the technical solution of the utility model is done any pro forma restriction, every foundation technical spirit of the present utility model all still belongs in the scope of the technical solution of the utility model any simple modification, equivalent variations and modification that above embodiment did.
