Vibratory roller is widely used in the constructions such as road, airfield runway, dykes and dams with the operating feature of its high-effect high-quality, and large exciting force consolidation effect is good, high efficiency.Exciting force is the centrifugal force that is produced by the exciting agency High Rotation Speed, and speed is faster, and centrifugal force is larger.The same larger centrifugal force of exciting agency eccentricity is also larger.Domestic single-drum road roller all is single-chamber type or bicavate vibrating device at present, and the bicavate vibrating device is two vibration cavity, two groups of exciting agencies, four vibration bearings.The load that each bearing of this device bears is large, has limited the rotary speed of exciting agency, and the less limit speed of bearing is higher but its load is relatively just little; Simultaneously single increasing eccentricity in this device certainly will cause exciting agency huge, has increased the difficulty such as production, installation and maintenance.Exciting force is large not, and then compaction force and operating efficiency are not high.Therefore under the constant condition of vibratory roller vibrative compacting wheel and exciting agency external form, obtain large exciting force, realize superpower compaction force, technology content and the market competitiveness that can improving product.
The utility model content
The technical problem that the utility model mainly solves provides a kind of road roller vibrating device of three-chamber exciting agency, in the situation that does not change Wheel for Vibrational Body of Vibratory Roller, exciting agency profile and bearing size, improve the rotary speed of exciting agency, the eccentricity of increase exciting agency, thereby improve the centrifugal force of exciting agency, realize increasing the main purpose of exciting force, and then realize the superpower compaction force of road roller, increase work efficiency.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: the road roller vibrating device that a kind of three-chamber exciting agency is provided, involving vibrations wheel body and vibrating motor, be provided with three vibration cavity in the described vibration wheel body, be provided with an exciting agency in each vibration cavity, described exciting agency is welded on the vibrating shaft of described vibrating motor, and links to each other with vibrating motor by shaft coupling; Described exciting agency is driven by vibrating motor and rotates, rotates synchronously with vibrating shaft.
Wherein, pass through spline joint between the axle of described exciting agency.
Wherein, be provided with lubrication oil in the described vibration cavity.
Wherein, described bearing is self-aligning roller bearing.
The beneficial effects of the utility model are: by be provided with three vibration cavity in the vibration wheel body, be provided with an exciting agency in each vibration cavity, three groups of vibration bearings in the vibration cavity reduce the load that each bearing bears than the bicavate vibrating device under the condition that does not change the bearing size like this, so that thereby bearing can bear the rotary speed that higher rotating speed improves exciting agency, increase the centrifugal force of exciting agency.
In addition, the axle of three groups of exciting agencies of series connection has strengthened eccentricity than the bicavate exciting agency so greatly by spline joint on the basis that does not change the exciting agency external form.
So that vibratory roller in working order the time, greatly improves centrifugal force, thereby greatly improved exciting force, has superpower compaction capacity by the combination of above-mentioned dual mode.
