Abstract
The utility model relates to an amplitude modulation vibration exciter for hollow eccentric disc and pertains to a roller vibration exciter. The vibration exciter comprises a hollow eccentric disc, a movable eccentric block, an inner shaft and a hollow shaft. The inner shaft goes through the hollow shaft and is connected with the movable eccentric block positioned in the hollow eccentric disc. The vibration exciter for hollow eccentric disc greatly increases control range of eccentricity regulation, therefore, in the formula P=M e Omega # + [2], the option space of exciting force is greatly increased, which is conducive to improving roller performance and compaction effect. After the synthesis of the exciting force generated by the movable eccentric block during working and the exciting force generated by the hollow eccentric disc, the synthesized exciting force is transmitted to the ground by a vibration bearing and a vibration wheel to realize compaction. The force of the vibration bearing is better than that of a vibration bearing in a stepless regulation vertical vibration exciter. For realizing serial application of two vibration exciters, the utility model can be applied to large-tonnage roller and can realize stepless regulation as well as manual regulation.

Background technology
At present, the conventional vibrator that uses on the vibratory roller, this vibrator is to be connected with vibrating shaft on the axial line of vibrating wheels, is connected with two fixed eccentric blocks on vibrating shaft; Also be connected with the movable eccentric block that can on vibrating shaft, rotate simultaneously.Usually there are two such equipments to be serially connected on the same axial line for the large-tonnage road roller, connect by splined shaft between the vibrator.This equipment can only produce two eccentric throws (two amplitudes), can not realize many amplitudes and ungraded amplitude.
Summary of the invention
The purpose of this utility model provides a kind of hollow eccentric disc amplitude modulation vibrator that can realize many amplitudes and ungraded amplitude.
The purpose of this utility model is achieved in that this vibrator is made of hollow eccentric disc, movable eccentric block, interior axle, hollow shaft, and interior axle penetrates to hollow shaft, is connected with movable eccentric block on the interior axle, and movable eccentric block is positioned at hollow eccentric disc.
Hollow eccentric disc is made of two eccentric discs, two hollow shafts, upper curved plate, lower curved plates, two eccentric discs are parallel to each other, on two eccentric discs, be connected with hollow shaft respectively, hollow shaft extends to two opposite directions, and its axle center is positioned on the same axial line, is connected with sliding bearing sleeve in the hollow shaft, hollow shaft is outward a spline, upper curved plate and lower curved plate be connected two eccentric discs between, upper curved plate is positioned at the upper end of eccentric disc, lower curved plate is positioned at the lower end of eccentric disc.
Hollow eccentric disc can be integral piece or weldment or composite member.
Movable eccentric block has interior axle, is connected with eccentric block on the interior axle, and the axle head of interior axle is a spline.
Beneficial effect: owing to adopted such scheme, hollow eccentric disc vibrator increases the eccentric throw modification scope greatly, makes P=Me ω
2In the formula, extensive space has been expanded in the selection of exciting force, helps the raising of road roller performance and consolidation effect.After the exciting force that exciting force that movable eccentric block produces at work and hollow eccentric disc produce is synthetic,, be passed to soil, realize compacting through vibrating wheels by vibration bearing.Vibration bearing stressed is better than the stressed of vibration bearing in the stepless regulated vertical vibration vibrator.Because the utility model can be realized two vibrator serial connections and use, thereby can be applied to the large-tonnage road roller.Can realize stepless regulatedly realizing manual regulation and control again, reach the purpose of this utility model.
