The present invention is the synchronous drive method with several parallelly installed eccentric shafts and typical synchronous drive mechanism. The typical synchronous drive mechanism consists of mainly two parallelly installed eccentric shafts, vibrating bearings, vibrating bearing seats, synchronous gear box, shaft coupler, etc. The vibrating bearings are mounted on the eccentric shafts and set on the vibrating bearing seats, the vibrating bearing seats are installed on the webs inside the vibration wheel, the synchronous gear box is located on the vibrating bearing seats, installed on the webs and has inside installed synchronous gear connected with the eccentric shafts via shaft coupler for driving. The present invention solves the problems of synchronously driving eccentric shafts.
Description
The present invention relates to driven in synchronism method and representative synchronization driving mechanism that a kind of many (more than two or two) eccentric shafts are installed in parallel, especially driven in synchronism method that multiple-eccentric shaft is installed in parallel in the vibrator of vibrating roller and representative synchronization driving mechanism belong to the road building machinery field.
The present invention is that typical case illustrates driven in synchronism method and the representative synchronization driving mechanism that multiple-eccentric shaft is installed in parallel with driven in synchronism method and the representative synchronization driving mechanism that two eccentric shafts are installed in parallel.
At present, the exciting agency of the vibratory roller of extensive use both at home and abroad all is the vibrator of single eccentric shaft (or two eccentric shaft series connected on an axis), its operating principle is to utilize the eccentric shaft of vibrator and the centrifugal force of eccentric block generation when rotating at a high speed to force the vibration of vibrating the crop rotation circumferencial direction, i.e. " circular vibration ", because there is the nuisance vibration of horizontal direction in this " circular vibration ", the compacting usefulness of existing vibratory roller is restricted; And, also exist certain ambient vibration to pollute, in order to improve the performance deficiency of " circular vibration " road roller, in recent years, the vertical vibration and the vibration vibrotechnique of road roller have been worked out, vertical vibration is that two eccentric shafts are installed in parallel in the horizontal direction in the vibrator housing, starting phase angle when the eccentric block of two eccentric shafts is installed equates, the driving of two eccentric shafts is to rotate as synchronous backward and realize by being directly installed on a pair of synchromesh gear on the eccentric shaft, because the vibrator housing does not rotate, so the eccentric block centrifugal force in the horizontal direction of two eccentric shafts of installing is relatively cancelled out each other, and only produces the exciting force on the vertical direction.The exciting agency of vibration vibration then is to be installed in parallel two eccentric shafts in vibrating wheels, starting phase angle when the eccentric block of two eccentric shafts is installed differs 180 °, two eccentric shafts drive two eccentric shafts by a central axis by synchronous cog belt and do synchronously rotation in the same way, and two eccentric shafts and eccentric block only produce when rotating in the same way synchronously and be parallel to each other but reverse centrifugal force forms alternate torque makes the vibration wheel body produce vibration to vibrate.But vertical vibration that above-mentioned prior art provides and vibration vibratory roller are difficult to enter the application stage, main cause, being because there is major defect in the exciting agency of vertical vibration wheel that prior art provides and vibration vibrating wheels, is that the synchronously driven method and the synchronous drive mechanism of two eccentric shafts that are installed in parallel in the exciting agency exists defective definitely.Two eccentric shafts that are installed in parallel in the vibration vibrating wheels by the synchronous cog belt driving are because the operating mode of road roller is abominable, so the functional reliability and the application life of synchronous cog belt are lower; And the driven in synchronism of two eccentric shafts that are installed in parallel in the vertical vibration wheel, because the amount of deflection that produces in existence of the end-play of vibration bearing and the eccentric shaft rotation changes, make the transmission center to center distance be installed in two synchromesh gears on two eccentric shafts in rotation, do the cycle and change, thereby cause two synchromesh gear application life short even can't normally move.
The object of the present invention is to provide a kind of new two or two driven in synchronism method and representative synchronization driving mechanisms that above eccentric shaft is installed in parallel, avoid in the exciting agency of vibration vibrating wheels, using synchronous cog belt and cause lower functional reliability and application life; The transmission center to center distance of two synchromesh gears did not change when eccentric shaft rotated in the exciting agency of assurance vertical vibration wheel, made vertical vibration and vibration vibratory roller can access real commercial Application.
The object of the present invention is achieved like this: two eccentric shafts that are installed in parallel in the vibrating wheels of will vibrating synchronously in the same way driving mechanism change synchronously gear driven mechanism in the same way into by synchronizing jugged tape drive mechanism, and synchromesh gear is avoided being directly installed on the eccentric shaft; Two synchromesh gears of two eccentric shafts that are installed in parallel in the vertical vibration wheel are also avoided being directly installed on the eccentric shaft, concrete method is: the design synchronous gear box, synchromesh gear and travelling gear are installed in synchronous gear box, the output of every synchromesh gear all by shaft coupling or other compact conformations, can the constant speed transfer torque, input with certain flexible coupling and corresponding eccentric shaft is connected, the transmission center to center distance of synchromesh gear equates fully with the distance between axles of two eccentric shafts; The installation base plate correspondence of synchronous gear box is positioned on the vibrating shaft bearing of two eccentric shaft inputs and is installed on the two ends former of vibration wheel body endoporus, the installation base plate of synchronous gear box and the locate mode of vibrating shaft bearing can be the seam boss, also can be that positioning sleeve or other modes are located, to guarantee the rigging position precision of two synchromesh gears and two eccentric shafts, because connection is to realize by having flexible shaft coupling between the eccentric shaft of every corresponding driving with it of synchromesh gear, avoided two eccentric shafts to exist owing to the end-play of vibration bearing when rotated fully and the amount of deflection of eccentric shaft changes transmission center to center distance and the engagement that changes synchromesh gear, made the transmission center to center distance of two synchromesh gears and the engagement keep initial installation accuracy constant.
