It is connected with each other, when so that motor 7 being run, drives helical screw 3 to rotate by first pulley 9, belt 13 and the second belt wheel 11.
It is understood, however, that can be installed using intermeshing and respectively instead of first pulley 9, belt 13 and the second belt wheel 11
To drive, helical screw 3 rotates gear in the shaft and helical screw 3 of motor 7 or helical screw 3 passes through shaft coupling
It along aligned is directly connected to be also feasible with the shaft of motor 7.
Fig. 2 shows the spiral shell of the driving mechanism according to the preferred embodiment in the utility model with the schematic isometric of partly cut-away
Female component, Fig. 3 are the exploded perspective views of the partly cut-away of nut assembly shown in Fig. 2.As shown in Figures 2 and 3, according to the utility model
The nut assembly 5 of the driving mechanism 1 of preferred embodiment includes with the internal screw thread 15a engaged with the external screw thread 3a of helical screw 3
Nut 15.In preferred illustrated embodiment, nut 15 include the general cylindrical with internal screw thread 15a first part 15b,
With with the second part 15d for accommodating the central through hole 15c of first part 15b, lead on second part 15d along center
Hole 15c's is diametrically opposite provided with the first hole 15e and the second hole 15f.First part 15b and second part 15d for example pass through
Screw 15g is fixedly attached to together.It should be understood that first part 15b can use such as oval shape or prismatic
Any suitable shape, second part 15d can also using from different other the suitable statuses of diagram hexahedral shape, such as eight
Embody shape in face.More it should be understood that first part 15b and second part 15d may be integrally formed, still, first part 15b
It is separately formed with second part 15d convenient for processing the first hole 15e and the second hole 15f on nut.In first part 15b and
In the case that second part 15d is integrally formed, the first hole 15e and the second hole 15f are formed with internal screw thread 15a's along nut 15
The diametrically opposite setting of threaded hole.
It as shown in Figures 2 and 3, further include being formed according to the nut assembly 5 of the driving mechanism of the preferred embodiment in the utility model 1
Have the link block 17 of the center cavity 17a for accommodating nut 15, on the side wall of center cavity 17a with the first hole on nut 15
15e and the corresponding position the second hole 15f are respectively formed with the third hole 17b and the 4th hole 17c communicated with center cavity 17a.Spiral shell
Female component 5 further includes a pair of of pin shaft, that is, the first pin shaft 19a and the second pin shaft 19b.
Fig. 4 is the cross section view of nut assembly shown in Fig. 2 for connecting with crossbeam.By passing through screw 15g by fixedly
The nut 15 that the first part 15b and second part 15d to link together is constituted is placed in the center cavity 17a of link block 17
It is interior.The third hole 17b that first pin shaft 19a is passed through on link block 17 is extended in the first hole 15e on nut 15, the second pin shaft
The 4th hole 17c that 19b is passed through on link block 17 is extended in the second hole 15f on nut 15.First pin shaft 19a and the second pin shaft
19b itself is permanently connected together with link block 17, such as by interference fit, but for the ease of mounting and dismounting, the
The first flange 19c and the second flange 19d are accordingly formed on an end of one pin shaft 19a and the second pin shaft 19b.First pin
Axis 19a is permanently connected together by passing through the screw 19e that the first flange 19c is screwed into link block 17 with link block 17, the

It is swung in a certain range around axis.In this way, causing the helical screw 3 that engages with nut 15 in the first pin shaft 19a and the due to vibrating
The inclination (that is, helical screw 3 is in non-vertical state) in X-direction that two pin shaft 19b are limited can be by nut 15 along first
Pin shaft 19a and the second pin shaft 19b is compensated in the movement of X-direction, since whirling vibration leads to the taenidium engaged with nut 15
Inclination of the bar 3 in the Y-direction vertical with X-direction can be by nut 15 around the swing of the first pin shaft 19a and the second pin shaft 19b
To compensate.Therefore, can be substantially reduced or eliminate by link block 17 be passed to by driven structure (such as then description
Simple shear knife-edge or double shear knife-edge bracket) on whirling vibration, to reduce the vibration that generates driven structure and noise.
Nut 15 is mobile relative to the first pin shaft 19a and the second pin shaft 19b and cause to wear in order to prevent, can on nut 15 the
The first anti-wearing liner 21a and the second anti-wearing liner 21b are accordingly fixedly disposed in one hole 15e and the second hole 15f.In this feelings
Under condition, internal diameter of the diameter less than the first anti-wearing liner 21a of the first pin shaft 19a, and the diameter of the second pin shaft 19b is less than second
The internal diameter of anti-wearing liner 21b.It should be understood that nut 15 can also otherwise with link block 17 or structure mutually interconnects
It connects, as long as nut 15 can be made to be restricted along a direction vertical with helical screw 3 relative to link block 17
Swing that is mobile and being restricted around a direction.
In the embodiment shown in fig. 1, conventional belt can be used although being mounted on second belt wheel 11 of 3 one end of helical screw
Wheel, but more preferably the second belt wheel 11 uses discharging type pulley assemblies 23, is transmitted to taenidium to further decrease motor 7
Vibration on bar 3.Fig. 5 is the discharging type belt wheel that very diagrammatically show with exploded perspective view according to the preferred embodiment in the utility model

Certainly, end cap 39 can be integrally formed with belt wheel 25.Lead to for the ease of the installation positioning of helical screw 3 and by axial load
It crosses second bearing 31 to be transmitted to bearing block 33 and be transmitted in turn on substrate 35, is additionally provided with axially position ring 43 and 44.Setting
Prevent helical screw 3 from falling off from discharging type pulley assemblies 23 in the gasket 45 and nut 47 of the end tip of helical screw 3.
As illustrated in figures 1 and 7, the belt wheel of discharging type pulley assemblies 23 is driven by first pulley 9 and belt 13 when motor 7
When 25 rotation, since belt wheel 25 passes through the end cap 39 being firmly connected with it and the key being arranged on end cap 39 and helical screw 3
Key 41 in slot is connect with helical screw 3, only in torque transfer to helical screw 3, so that helical screw 3 is with belt wheel 25 1
Play rotation.In this manner it is achieved that the function that driving helical screw 3 rotates.On the other hand, belt wheel 25 is also connected by first bearing 27
It is connected to off-load sleeve 29, and off-load sleeve 29 is connected on substrate 35 further through bearing block 33.In this way, when belt wheel 25 rotates,
Radial load (such as belt tension) on belt wheel is passed to first bearing 27 and is then communicated to off-load sleeve 29.Due to
Off-load sleeve 29 is connected on substrate 35 further through bearing block 33, and radial load is eventually transferred to substrate 35 by bearing block 33
On.Therefore, it is possible to avoid generating moment of flexure on helical screw 3, so that the bending deformation of helical screw is avoided, so that helical screw
It steadily rotates, reduces work noise and vibration.
