It should be noted that in order to adapt to same supporting mechanism, facilitating the replacing of disparate modules to use, Cycloid Ball Transmission
Module, involute transmission module, floating disc module, floating steel-ball type module, steel ball circular groove type module, bipyramid pin module and
The tooth form or structure of pin-hole type module are based on same eccentric distance e, and the eccentric distance e is the eccentric throw of gearratio of cycloid axle formation.Specifically,
When the eccentric throw of gearratio of cycloid axle formation is e, then
In Cycloid Ball Transmission module, the tooth profile equation of epicycloid groove 205 is on epicycloid disk 201：
Z in formula0--- steel ball quantity；
E --- eccentric shaft away from；
K --- curtate ratio；
θ1--- the corresponding central angle of arc length being scrolled through on epicycloid basic circle, referred to as epicycloid generate angle；
In Cycloid Ball Transmission module, the tooth profile equation of hypocycloid groove 206 is on hypocycloid disk 203：

107, can realize replacing Cycloid Ball Transmission module completely under the conditions of other parts are not changed, it is ensured that structure is consistent.
All of equispeed output mechanism module design is based on same eccentric distance e, all equispeed output mechanism module sizes
Essentially identical, while all of bolt connection positioning is all identical, all bolt thicknesses are identical, it is ensured that can realize quick-replaceable
Equispeed output mechanism module；Other mechanisms need not be changed during replacing, it is ensured that structure is consistent.
Equispeed output mechanism driving principle is divided into two kinds, and a kind of is using two guide rods of turning-block linkage two of prismatic pair
The equal principle design of instantaneous angular velocity, wherein two guide rods are mutually perpendicular to, including floating disc module, floating steel-ball type mould
Block；Another kind is including the steel ball circular groove type using the equal principle design of the crank instantaneous angular velocity of parallel double crank mechanism two
Module, bipyramid pin module, pin-hole type module.The two effect is all to realize that the constant speed that gearratio is 1 is passed between two-parallel axis
Pass.
The first principle by taking steel-ball type module of floating as an example, referring to Figure 11, floating steel-ball type input disc 501 and floating steel ball

E/2, the bottom land of annular ball groove 604 is in 90 degree, therefore groove depth h is also e/2, according to groove depth conditionSteel ball annular groove is passed
The diameter of steel ball can use in dynamic steel ball group 603In bipyramid pin module, in order to realize equispeed output i.e. shape
Into parallel double crank mechanism, input disc taper pin 703 should be e with the centre-to-centre spacing of output panel taper pin 705, while taper pin head is taper, therefore
The average diameter that taper pin need to be ensured is e；In pin-hole type module, in order to realize that equispeed output forms parallel double crank mechanism,
Input disc pin-and-hole 803 and the centre-to-centre spacing of pin long 805 are e, the i.e. diameter of input disc pin-and-hole 803 than the big 2e of the diameter of pin long 805.
