As 0≤F ＇ ＜ F, when the first nut 41 moves to the position in gap just, because F ＇ and F resultant direction to
Under, identical with the direction of motion of the first nut 41, now, of short duration weightlessness, downward acceleration occurs in the first nut 41
Degree can increase the movement velocity of the first nut 41, then hit the lower interface in gap, so that impact noise is produced, such case
Typically periodically occur with the rotation of screw mandrel 40.
As F ＇ >=F, F ＇ and F resultant direction upwards, with the direction of motion of the first nut 41 on the contrary, now, the first spiral shell
Weightlessness will not occur for mother 41, and mechanism will not produce noise and shake in the process of running；
2., screw mandrel 40, which is rotated, drives the upward uniform motion of the first nut 41
As 0≤F ＇≤F, F ＇ and F resultant direction downwards, with the direction of motion of the first nut 41 on the contrary, now, first
Weightlessness will not occur for nut 41, and mechanism will not produce noise and shake in the process of running；
As F ＇ ＞ F, when the first nut 41 moves to the position in gap just, because F ＇ and F resultant direction are upward,
Identical with the direction of motion of the first nut 41, now, of short duration weightlessness occurs in the first nut 41, and mechanism in the process of running can
Produce noise and shake.
The above-mentioned two motion process of comprehensive first nut 41 is understood, when meeting F ＇=F, can avoid the first nut 41
Shock is produced with screw mandrel 40 because of the fit clearance between screw mandrel 40 in motion process up and down, and then avoids screw mandrel
Nut body produces noise and shake in the course of the work.
Screw mandrel protective cover 46 is used for protecting the bar hole 47 for being provided with and being vertically distributed on screw mandrel 40, screw mandrel protective cover 46, first
The nut 42 of nut 41 and second has exposes to screw mandrel protective cover 46 locally through bar hole 47.In addition, in order that the first spiral shell
Female 41, second nut 42 and the load on the first nut 41 can be moved steadily, and the first nut 41 is protected with screw mandrel
Guiding fit structure is equipped between cover 46 and between the second nut 42 and screw mandrel protective cover 46.Being oriented to fit structure can adopt
With the fit structure of conventional convex tendon and groove, herein not reinflated description.
Embodiment two：
As shown in Figure 7 and Figure 8, the transmission mechanism 4 in the present embodiment includes gear 48, rack 49, guide rail 44 and connecting plate
45, gear 48 is driven by motor 3, and rack 49 is vertically arranged and is meshed with gear 48, and rack 49 is made under the transmission of gear 48
Elevating movement, guide rail 44 has two and on the left plate 101 and right plate 102 of mounting bracket 1, installation in the middle of connecting plate 45
