Embodiment
1st, the elastic force relational expression of spring 15, the direct relation of both big moments of torsion of torsion motor 14 that slows down are：
Spring constant：Represented with k, when the springs are compressed, often increase the load (kgf/mm) of 1mm distances；
Spring constant formula (unit：kgf/mm)：K=(G × d4)/(8×Dm3×Nc)
The modulus of rigidity of G=wire rods：Piano wire G=8000, stainless steel silk G=7300；PHOSPHATE BRONZE WIRE G=4500, pyrite
Line G=3500,
D=line footpaths, Do=OD=external diameters, Di=ID=internal diameters, Dm=MD=central diameters=Do-d, N=numbers of total coils, Nc=has
The effect number of turns=N-2,
If the compression spring scheme that mechanism adopts is：Line footpath=1.0mm, external diameter=7.0mm, number of total coils=10.5 circle, pressure
Contracting distance：4mm, wire quality=rustless steel steel wire
K=(G × d4)/(8×Dm3× Nc)=(7300 × 1)/(8 × 216 × 8.5)=0.497kgf/mm
Then load is 1.988kgf.
DC speed-reducing, i.e. toothed gearing electric motor, are on the basis of common DC motor, to add associated gear deceleration
Case.The effect of gear reduction box is to provide relatively low rotating speed, larger torque.Meanwhile, the different speed reducing ratio of gear-box can be carried
For different rotating speed and torque.Stall torsion under load torsion and resting state is typically directly provided by motor manufacturer, typically
More than 4kgf/mm.
Coefficient of friction between common metal part and metal screw is 0.11～0.13, there is the situation of lubricating oil therebetween
Under, coefficient of friction can be less,<0.26.The stall torsion of the big torsion reducing motor that mechanism selects is much larger than this value.
2nd, catch ejects the impact to support
According to example above, impulsive force is drawn less than 2N by above formula, in general the surrender of 304 corrosion resistant plates is strong
Spend for 310MPa, that is, being external diameter 7mm with spring contact surface, calculating, then static pressure is produced for the spring of line footpath 1mm
Pressure is 0.03MPa, and catch ejects the kinetic energy of produced impulsive force and provided by pressure, excludes motion loss, then impulsive force
Static pressure is should be less than, another catch is 33mm with the contact area of cradle wall2Left and right, much larger than the 24mm of spring contact area2Then
Pressure is certainly less than 0.03MPa, and 304 steel brackets cannot much bent, still more damaged.
3rd, long term power of the catch to screw rod
According in example above, the static active force to screw rod of catch is 2N or so, and catch is with the contact area of screw rod
5mm2, then static pressure is 0.4MPa, is also much not enough to damage screw rod and catch.
4th, process-time relational expression
The big rotating speed of torsion reducing motor of gear train is relevant with the proportioning of gear train and motor core rotating speed itself, it is assumed that electricity
Machine rotating speed is w (turning/s), and from the point of view of the screw thread according to the M3 adopted in example, standard pitch is 0.5～0.3mm, then one second electricity
Machine screw rod can promote motor in process i.e. mechanism to advance or retreat most 0.5w mm, then when process is L, L/ is most needed soon
The time of 0.5w (s) completes whole processes.In example, process is 15mm, and rotating speed is 2 turns/s, then most need time 15s altogether soon.
5th, long cylinder gos deep into the depth of groove
Long cylinder gos deep into that groove is unsuitable long, plays limiting the six direction degree of freedom of tear-away part and (be divided by long cylinder
Beyond the rotary freedom of axle) effect.This distance should be close to body diameter, so be easy to go deep into the part of groove
Sphere can be processed as, the disengaging being easy to behind tear-away part.
6th, long cylinder dome is to the fit tolerance between circular hole and groove
This tolerance takes 0.15～0.2mm and is advisable, when this fit clearance both can ensure that overall pinning, removable part
Will not too rock, it is also possible to be relatively easy to when removable part needs and departs from constraint.
Note：Long cylinder gos deep into the depth of groove, cylindrical shape (deeply part is dome sphere), fit tolerance these designs
Consider in order to ensure removable part when integrated model is pinned, it is firm to rock not too much, also ensure when separation is needed, can
Separate section can smoothly depart from will not occur unexpected stuck situation.
7th, remotely control
The separable realization of remotely control of single unit system, by the powerful work(based on the communication of RDSS Big Dipper technologies short message
Can, Big Dipper Microstar can be relied on and realize for instruction being remotely assigned to device mainboard, so as to pass through the logical of the MCU controlled motors on mainboard
Power-off, carrys out controlled motor action, and the Design of Mechanical Structure of cooperation single unit system cleverly realizes the separable company of remote-controllable
Connect.
