Abstract
The utility model relates to a vibrator bias torque regulating mechanism for a vibrative pile driving hammer, which is mainly characterized in that a spline 15-2 is processed in a driven shaft 10 of the vibrator, an adjusting shaft 9 of a large guide distance helical spline 15-1 is independently arranged and processed on the end part of the driven shaft on the same axes, and the adjusting shaft 9 is fixedly provided with a synchronizing gear 8 engaged with a synchronizing gear 7 which is fixedly installed on the end part of a drive shaft 2. A connection shaft 15 processed with a spline and a large guide distance helical spline causes the driven shaft 10 and the adjusting shaft 9 to be connected with each other via a spline match, but when the connection shaft 15 is in an axial displacement, the adjusting shaft 9 relative to the driven shaft 10 namely the drive shaft 2 relative to the driven shaft 10 are in a relative rotation to change an included angle between bias blocks, thus realizing a regulation of the bias torque.
Description
The utility model is about the improvement of stepless adjustment vibrator eccentric moment invention, particularly be a kind of vibrator eccentric moment adjusting mechanism that is suitable for vibrohammer.
In the prior art, there is following several form in the mechanism of the stepless adjustment eccentric moment of vibrator: 1. shifting slide gear formula: then utilize a gear shaft that is processed with a pair of rotation direction opposite helical angle to move axially, by with its two synchromesh gears that are meshed simultaneously, angle is changed changes eccentric moment; 2. adopt one to be processed with the adjustment axle of the opposite big helical pitch helical spline of a pair of rotation direction and a pair of adjustment gear that is connected with its spline, be meshed with the gear on eccentric axon is housed, when the adjustment axle moves axially, then change angle between the eccentric block, realize the adjustment of eccentric moment; 3. adopt a sleeve that is processed with opposite big helical pitch internal helix spline of rotation direction and external splines.The internal spline of sleeve matches with the adjustment axle that is installed with a synchromesh gear, the external splines of sleeve matches with the adjustment cover that is installed with a synchromesh gear, is fixedly mounted on to adjust axle and adjust the gear that puts to be meshed with synchromesh gear on the eccentric axon respectively.When the helical spline sleeve moves axially, then change the angle between the eccentric block, realize the adjustment of eccentric moment.Above-mentioned three kinds of forms all are that important function has been brought into play in the adjustment of vibrator eccentric moment, also produce complex structure simultaneously because there being the deficiency of each comfortable configuration aspects, problems such as poor reliability or installation difficulty, when the common drawback of above-mentioned three kinds of forms is that guiding mechanism all is the mechanism that is independent of outside the eccentric axon, because mechanism's complexity has brought the height of vibrator to increase, reduced the non-loaded amplitude of vibrator, and cost is higher.
In view of the problem that known technology exists, the purpose of this utility model aims to provide a kind of scientific and reasonable for structure, and good reliability is processed vibrator eccentric moment adjusting mechanism easy to assembly.
The utility model is realized as follows: the vibrator eccentric moment adjusting mechanism includes drive unit, fixing synchromesh gear, movable synchromesh gear, fixed eccentric block, movable eccentric block, driving shaft and driven shaft, it is characterized in that being processed with in the driven shaft spline, the end of driven shaft independently is equipped with the adjustment axle of big helical pitch internal helix spline on same axis, adjust a hard-wired synchromesh gear in driving shaft end of going up synchromesh gear of fixed installation and eccentric body and think engagement, be processed with the connecting axle of spline and big helical pitch helical spline, cooperation by key is connected driven shaft with the adjustment axle, described connecting axle one end is connected with drive unit on being fixedly mounted on casing by bearing, eccentric block on the described vibrator is corresponding respectively to be installed on driving shaft and the driven shaft, and the quiet eccentric moment of every eccentric block equates, in the described angle adjusting range that is installed in the fixed eccentric block on driving shaft or the driven shaft is 0-180 °, the described drive unit that is fixedly mounted on the casing can be that the oil pressure actuated that oil cylinder piston is formed also can be driven by leading screw, described driven shaft also can be processed into flat key or big helical pitch helical spline endoporus, the corresponding fit key of connecting axle also changes flat key or big helical pitch helical spline into, but the rotation direction of big helical pitch helical spline should be opposite with the big helical pitch helical spline rotation direction in adjusting axle.
The utility model is compared with known technology, has scientific and reasonable for structurely, and weight reduction improves amplitude, reduces cost.According to the vibrator eccentric moment adjusting mechanism of the utility model design motif made, produce positive result of use will for the eccentric moment adjustment of vibrohammer.
