Number comparison module sends the control signal to motor 20 after being carried out to two tach signals, so as to effective regulation speed.
For the axial force of central gear 50 caused by helical gear of the absorption in planetary stage 60, the present invention uses
Central gear 50 and hollow shaft 30 are arranged to detachably be connected with support shaft 15.Driving body 90 can be spheroid, or
Cylindrical roller.When driving body 90 is using cylindrical roller supporting axial force, aperture 31 and the shape and cylinder of groove 51
The profile of roller is adapted, and the axial direction of cylindrical roller and the axial direction of connecting shaft 40 are perpendicular, hollow shaft 30, connecting shaft
40th, central gear 50 and planetary stage 60 cylindrical roller during transmission can rotate but without absorption in accommodating chamber
Axial force in transmission process.
Driving body 90 is made up of the small material of coefficient of friction.Driving body 90 can be spheroid, and the corresponding accommodating chamber is
The spherical cavity being adapted with spheroid form, spheroid fit in accommodating chamber and with the inwall of accommodating chamber.
Driving body 90 can be cylindrical roller, and the corresponding accommodating chamber is the post being adapted with cylindrical roller shape
The cavity of the bodily form, cylindrical roller in the accommodating chamber, the curved wall of cylindrical roller respectively with aperture 31 and the phase of groove 51
Fitting, the axial direction and the axial direction of connecting shaft 40 of cylindrical roller are perpendicular.
Aperture 31 is radial hole or transverse holes.Aperture 31 is opened in hollow shaft 30, when driving body 90 is spheroid, each
Aperture 31 and the shape of spheroid are adapted.In the periphery of central gear 50 at least provided with two or more spheroids.Central gear 50
On open up the groove 51 of a circumferential.Groove 51 is located at towards on the periphery of the hollow shaft 30 of central gear 50, central gear
It is axial arranged between 50 groove 51 and the inner edge profile 42 of connecting shaft 40.After central gear 50 and hollow shaft 30 assemble, spheroid
It is inserted into accommodating chamber, spherical part is located at the aperture 31 of hollow shaft, and part is in the groove 51 of central gear 50.Ball
Body can freely rotate in accommodating chamber, can transmit the axial direction of central gear 50 and hollow shaft 30 in the two directions by spheroid
Power.The size of groove 51 and spheroid on central gear 50 is adapted, and spheroid is diametrically played a role, so that hollow shaft
30 and the radial motion power of central gear 50 be compensated.
In order to prevent spheroid from being dropped out from aperture 31, can be pushed away by annular construction member 91 or the like via hollow shaft 30
Pressure, the radial direction of accommodating chamber is sealed by annular construction member 91, so that the radially movable of spheroid is protected.Hollow shaft 30, which is provided with, to be used
In the circlip 92 of axial restraint annular construction member 91.Circlip 92 is arranged in hollow shaft 30, so as to solid well on axial direction
Determine annular construction member 91, well prevent the axial displacement of annular construction member 91 under assembled state.Annular construction member 91 is along driving body
90 periphery is set, and is sheathed in hollow shaft 30.
Driving axle housing includes left end shell 11, enclosure body 12 and the right-hand member shell 13 set gradually, left end shell 11 and right-hand member shell
13 are detachably connected by locking screw spigot 14 with enclosure body 12 respectively.
Traditional connection side can be used by locking screw spigot 14 between left end shell 11, enclosure body 12 and right-hand member shell 13
Formula is joined directly together, i.e., locking screw spigot 14 is each passed through into left end shell 11 and enclosure body 12 along the axial direction of left half axletree 81 respectively
And it is locked between enclosure body 12 and right-hand member shell 13.But this sample loading mode is used to be used when drive axle to a timing
Between after locking screw spigot 14 will inevitably loosen.Once locking screw spigot 14 loosens, i.e., it can make left end shell 11
Axial play occurs for the connection between enclosure body 12 or enclosure body 12 and right-hand member shell 13, so that in driving axle housing
Part produce loosening make to be connected between each part it is unreliable, cause the normal works of all parts in driving axle housing by
Serious influence.
Therefore, optimization connected mode will be used to make to be reliably connected between left end shell 11, enclosure body 12 and right-hand member shell 13.It is excellent
Changing connected mode includes:The first protruding block 121 is respectively equipped with enclosure body 12 with the junction of left end shell 11 and right-hand member shell 13
With the second protruding block, the first protruding block 121 and the second protruding block are set along the raised axially outward of left half axletree 81, left end shell 11
It is convex with the first projecting slot 111 and second for being respectively equipped with adaptable with the first protruding block 121 and the second protruding block on right-hand member shell 13
Grooving, the first projecting slot 111 and the second projecting slot cover on the first protruding block 121 and the second protruding block respectively, and first is raised
The first perforate is offered in the projecting slot 111 of block 121 and first respectively, locking screw spigot 14 includes the He of the first locking screw spigot 141
Second locking screw spigot, the first locking screw spigot 141 are arranged in the first perforate and by the first protruding block 121 and the first projecting slots
111 lockings are connected, and the setting direction of the first locking screw spigot 141 and the axial direction of left half axletree 81 are perpendicular.Second protruding block and
Offer the second perforate in second projecting slot respectively, the second locking screw spigot be arranged in the second perforate and by the second protruding block and
The locking of second projecting slot is connected, and the setting direction of the second locking screw spigot and the axial direction of left half axletree 81 are perpendicular.Using so
Mode will be connected between left end shell 11 and enclosure body 12 and enclosure body 12 and right-hand member shell 13, even if when the first clamping screw
The locking screw spigot of part 141 or second loosens, and does not also interfere with the normal work of drive axle.With the first locking screw spigot 141
Exemplified by loosening, when the first locking screw spigot 141 loosens, the first bolt part 141 will be in the first perforate along vertical
Relatively moved in the direction of the first protruding block 121 or the first projecting slot 111, due to the locking side of the first locking nut 141
To perpendicular with the closure of left end shell 11 and enclosure body 12, therefore left end shell 11, enclosure body 12 can't be caused to send out
It is unreliable that raw loosening causes to connect, and greatly enhances the security used.
