The utility model content:
Its purpose of the utility model provides a kind of circumferential angle position adjustable shaft coupling with regard to being to overcome above defective; Can adapt to and under the working condition of high rotating speed, heavy load, be used for coupling two coaxial line drive shaft system; And can let this system carry out position, ± 6 ° of circumferential angles adjustment fast, simply along diameter of axle circumferencial direction, have again transmit that moment of torsion is big, running steadily, the characteristics of long service life, low cost of manufacture.
The utility model comprises for realizing the technical scheme that above-mentioned purpose is taked; It is made up of left half a coupler, right half a coupler, left hand thread crank block, right-handed thread crank block, adjusting screw mandrel, screw mandrel adjustment screw, locating piece, splined shaft retaining plate and flange clamping screw; Left side half a coupler end face has the crank block guide groove, and flange locking screw hole drill becomes cylindrical hole; Right half a coupler end face has crank sliding pin guide groove, and flange locking screw is the long waist shaped slotted eye; Left hand thread crank block, right-handed thread crank block are respectively charged in the guide groove of left half a coupler, right half a coupler; The two ends of regulating on the screw mandrel are respectively equipped with the equidistance reverse thread, two crank block screws with regulate the screw mandrel couplet that matches.
Described left hand thread crank block is square, and the right-handed thread crank block is a cylindrical pin shape, and the hole screw thread of two crank blocks is respectively the left and right screw thread that revolves of equidistance.
The two ends screw thread of described adjusting screw mandrel is uniform pitch and the opposite screw thread of rotation direction, regulates the screw mandrel end and is provided with locating piece.
The end of described right half a coupler is provided with the splined shaft retaining plate.
Compared with prior art, the advantage of the utility model is,
1, circumferentially the adjustment of position, angle is accurate, efficient and convenient in limited range for this device, low cost of manufacture, characteristics such as its bearing torque is big, safe and reliable, long service life.
2, having can be simple and easy, be used to adjust a kind of novel coupler of power transmission shaft in the fine setting of the position, angle of circumferencial direction fast; Suit in metallurgical rolling machinery, to be used for coupling two coaxial line drive shaft system, and this system is carried out the adjustment of position, ± 6 ° of circumferential angles along diameter of axle circumferencial direction.The elaboration screw-thread steel that reaches rolling high added value is to the accurate adjustment requirement of the phase place (angle) of adjusting upper and lower two rolls.

The specific embodiment
Embodiment; Like Fig. 1, Fig. 2, Fig. 3, Fig. 4 and shown in Figure 5; It by left half a coupler 1, right half a coupler 4, left hand thread crank block 7, right-handed thread crank block 9, regulate screw mandrel 8, screw mandrel adjustment screw 2, locating piece 3, splined shaft retaining plate 5 and flange clamping screw and form; Left side half a coupler 1 end face has the crank block guide groove, and flange locking screw hole drill becomes cylindrical hole; Right half a coupler 4 end faces have crank sliding pin guide groove, and flange locking screw is the long waist shaped slotted eye; Left hand thread crank block 7, right-handed thread crank block 9 are respectively charged in the guide groove of left half a coupler 1, right half a coupler 4; The two ends of regulating on the screw mandrel 8 are respectively equipped with the equidistance reverse thread, two crank block screws with regulate screw mandrel 8 couplet that matches.
Described left hand thread crank block 7 is square, and right-handed thread crank block 9 is a cylindrical pin shape, and the hole screw thread of two crank blocks is respectively the left and right screw thread that revolves of equidistance.
The two ends screw thread of described adjusting screw mandrel 8 is uniform pitch and the opposite screw thread of rotation direction, regulates screw mandrel 8 ends and is provided with locating piece 3.
Left and right revolving in the guide groove that the screw thread crank block is respectively charged into two half a couplers made constant speed in opposite directions or reverse shuffle through the left and right threaded adjusting screw mandrel driving left and right slide block that revolves.Crank block is packed into and is done the straight line slippage in the guide groove of left half a coupler end face, and the crank sliding pin is packed into and done the angle slippage in the guide groove of right half a coupler, thereby makes two half a couplers can do the angular displacement adjustment of circumferencial direction.
Because two crank blocks are made constant speed in opposite directions or during reverse shuffle, it is very little that crank revolves the angle that moves to two half a couplers, and two cranks constitute couple, regulate screw mandrel and crank block is played spiral move to power, accomplish the adjustment of position, angle thereby drive two half a couplers by crank.So can be very easy and convenient and can very accurately reach the adjustment requirement of position, circumferential angle.
In the slide block guide groove of left half a coupler; The fixedly locating piece and the screw that locks screw mandrel of screw mandrel are housed; Make screw mandrel and crank block accurate stationary positioned in guide groove; Move for preventing scurrying of splined shaft at half a coupler and splined shaft assembling back, on splined shaft, have back stop slot, the splined shaft retaining plate pins right half a coupler.
The step of position, the circumferential angle of the utility model practical implementation adjustment does
:
1, unclamps the clamping screw and the screw mandrel lock-screw of left and right half a coupler adpting flange.
2, turn is regulated screw mandrel pulling crank block (sliding pin) and two half a couplers are done position, circumference angle is accurately adjusted.
3, adjustment need only be locked flange bolt after finishing and the screw mandrel lock-screw gets final product.
