The specific embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing:
Extremely shown in Figure 3 by Fig. 1, this kind low speed revolution torsional oscillation formula power set, comprise a columnar power box 12, in addition, described unit head also comprises hydraulic motor 1, motor base 2, final drive shaft 3, upper cover plate 4, driving bevel gear 5, revolution power transmission shaft 6, two driven bevel pinion group 7, cross binding axle 8, two vibration eccentric block group 9 and bearing group 13 that the vibration eccentric block consists of that driven bevel pinion consists of.Wherein, described hydraulic motor 1 is fixed on the motor base 2, and the turning cylinder of this motor is connected with final drive shaft 3; The bearing formation that final drive shaft 3 passes upper cover plate 4 central authorities is rotationally connected; The coaxial fixedly driving bevel gear 5 in the lower end of final drive shaft 3, the central cavity of passing described driving bevel gear 5, revolution power transmission shaft 6 is connected with final drive shaft 3 by spline.
The center of described cross binding axle 8 has the hole of passing through for revolution power transmission shaft 6, its two ends then are fixed with bearing group 13, to realize two driven bevel pinions are installed in by bearing the both sides of cross binding axle 8, two vibration eccentric blocks are separately fixed at the outside of two driven bevel pinions.
At last, described revolution power transmission shaft 6 is connected by the Kong Houyu drilling rod of cross binding axle 8 centers, and driven bevel pinion group 7 is meshed with described driving bevel gear 5, and the motion mode of two driven bevel pinions is for rotating in opposite directions; The two ends of described cross binding axle 8 pass behind the sidewall of power box 12 fastening by left gland 10 and right gland 11 respectively; Aforementioned final drive shaft 3, upper cover plate 4, driving bevel gear 5, revolution power transmission shaft 6, driven bevel pinion group 7, cross binding axle 8, vibration eccentric block group 9 and bearing group 13 interconnect the rear described power box 12 that all is positioned at.
For adapting to power box, most preferred vibration eccentric block structure is semicircular arc.
The course of work of the present utility model is as follows:
During use, drive final drive shaft by low speed high torque hydraulic motor, drive and the splined revolution power transmission shaft of final drive shaft simultaneously; Then the revolution power transmission shaft links to each other with drilling rod by the interstitial hole of fixed cross binding axle, and rotary output shaft provides the power such as the rotating moment of torsion of drilling rod, has realized creeping into of drilling rod.Simultaneously, driving bevel gear drives two driven bevel pinions and dallies at the cross binding axle, vibrates eccentric block generation out-of-alignment by the driven bevel pinion drive of two idle running and rotates in opposite directions, thereby produce torsional oscillation.Owing to when rotating speed is crept in transmission, will transmit the reciprocating rotating moment of torsion, therefore requiring the connection between the drilling rod must adopt key with bolt combination or adopt pin to be connected.
When low speed high torque hydraulic motor is passed to driving bevel gear with power by final drive shaft, driving bevel gear drives driven bevel pinion and rotates, and driven bevel pinion is in opposite directions rotary state always.Because driven bevel pinion is to rotate simultaneously around fixing horizontal back shaft with the vibration eccentric block, they have certain distance apart from the centre of gyration, and therefore the centre of gyration produces torsional moment relatively; Driven bevel pinion is with vibration eccentric block 360 ° of rotations, the torsional moment that produces forward for a moment, backward, will form twisting vibration for a moment; Twisting vibration passes and passes at last drilling rod by bearing, horizontal back shaft, left and right sides gland, cylinder casing, has realized the torsional oscillation of drill bit.Because what adopt is low speed high torque hydraulic motor, so this vibrates and is the low frequency torsional oscillation, and this is very effective for overcoming external resistance.
