Gear drive of the present utility model comprises gear disk 3, gland dish 4 and hubcap 5.This gear disk 3 is flat circular cylindrical shape on the whole, and outside is equally spaced is provided with a plurality of gear teeth 35.The center of this gear disk 3 is provided with circular rotating shaft through hole 32.This rotating shaft through hole 32 is for accommodating the end of drive shaft 5.These rotating shaft through hole 32 arranged outside have the gland groove 31 of toroidal, and this gland groove 31 matches for accommodating this gland dish 4 with the shape of this gland dish 4.The rotating shaft setting of parallel this gear disk 3 of outer side wall of this gland groove 31, madial wall arranges at an angle with the axes of rotation skew of this gear disk 3.The madial wall of this gland groove 31 coordinates definition one clamping boss 33 with the sidewall of this rotating shaft through hole 32.This clamping boss 33 is the boss that hollow outer side surface is taper on the whole, and rotating shaft through hole 32 is positioned at the axle center of this clamping boss 33.
In a preferred embodiment, the thickness of this gear disk 3 is 25 millimeters, and the diameter of this rotating shaft through hole 32 is 25 millimeters.14 millimeters of the degree of depth of this gland groove 31, the height of this clamping boss 33 is 14 millimeters.The diameter of these gland groove 31 outer side walls is 95 millimeters.This clamping boss 33 is 36 millimeters with the diameter of these indent 31 intersections, bottom, and the larger diameter of the madial wall of these clamping boss 33 bottom gland grooves 31 is 36 millimeters.The small diameter of the madial wall of this gland groove 31, the top diameter of this clamping boss 33 is 32 millimeters, this top diameter is also commonly called port diameter.
In the bottom of this gland groove 31, have 6 screw holes 34, this screw hole 34 extends to another surface of this gear disk 3 from the bottom of this gland groove 31, for running through the through hole of this gear disk 3.In alternate embodiments, this screw hole 34 can be also blind hole.These 6 screw holes 34 are about rotating shaft symmetry and the equidistantly distribution of this gear disk 3, and the line angle between any two screw holes 34 and this axis is 60 degree.In a preferred embodiment, this screw hole 34 is the hole of M8 screw.
The fixing locking device that this gland dish 4 is disc-shapes.Concrete, in this gland dish 4, be provided with boss fixed hole 41, end cap straight hole 42 and a plurality of via hole 43.This boss fixed hole 41 is cone shape hole, and the diameter of conical lower portion is 35 millimeters, and the diameter of conical top is 33.4 millimeters, and the distance between top and bottom (the taper hole degree of depth) is 9 millimeters.This boss fixed hole 41 is arranged on the center of this gland dish 4, has common central shaft with this gland dish 4.The bottom of these boss fixed hole 41 larger apertures and a flush of this gland dish 4, the smaller aperture due top of this boss fixed hole 41 is positioned at the inside of this gland dish 4 and connects this end cap straight hole 42.
This end cap straight hole 42 is cylindrical hole, with this gland dish 4 and this boss fixedly via hole 41 have common central shaft.In better embodiment, the diameter of this end cap straight hole 42 is 35 millimeters, and an one bottom joins with the top of this boss fixed hole 41, another flush of another bottom and this gland dish 4.In better embodiment, the height of this end cap straight hole 42 is 6 millimeters, so this end cap straight hole 42 coordinates two bottom surfaces running through this gland dish 4 with this boss fixed hole 41.
The quantity of this via hole 43 is 6, is the via hole of hexagonal countersunk screw in M8x30, and its distribution on this gland dish 4 is corresponding one by one with the distribution of this screw hole 34 on this gear disk 3.
On this cover clamp dish 4, be also provided with two screw through-hole (not shown), these two screw through-hole are on the circumference of this via hole 43.The effect of these two screw through-hole is: when disengage gear dish, with screw, eject gland dish 4, make cone boss unclamp transmission shaft.
This hubcap 5 is thin rounded flakes shape, and centre has the locking hole 51 that runs through this hubcap 5.The diameter of this hubcap 5 is less than the diameter of this end cap straight hole 42 and is greater than this boss fixed hole 41 away from the diameter of one end of this gear disk.
Gear drive of the present utility model also comprises a plurality of screws, the M8 screw that this screw is standard.When mounted, the end of rotatingshaft 6 is inserted the rotating shaft through hole 32 of this gear disk 3 from the opposing side of gland groove 31, the end in these rotatingshaft 6 insertion rotating shaft through holes 32 and the interior profile of this rotating shaft through hole 32 are substantially identical.The gland groove 31 of this gear disk 3 is towards the side away from this rotatingshaft 5.The conical lower portion of the boss fixed hole 41 of this gland dish 4, towards this gear disk 3, embeds gland groove 31 and the clamping boss 33 of this gear disk 3 from a side relative with this rotatingshaft 6 of this gear disk 3.In present embodiment, when embedding, because the conical lower portion diameter of the boss fixed hole 41 of gland dish 4 is less than the base diameter of clamping boss 33, the conical top diameter of boss fixed hole 41 is greater than clamping boss port diameter, between the bottom of the conical lower portion of this boss fixed hole 41 and this clamping boss 33, this gland dish 4 also has the gap of 6 millimeters between the surface of this gland groove 31 is with these gland groove 31 bottom surfaces.Each screw is screwed into this screw hole 34 through after corresponding via hole 43.These 6 screw symmetries are firmly locked this gland dish 4 in this this gland groove 31 completely, extruding clamping boss 33 male cone (strobilus masculinus)s that cooperatively interact of the cone structure by this boss fixed hole 41 and this clamping boss 33 now, tightening force is converted into axial enclasping force, make the diameter Stepwize Shrink of this rotating shaft through hole 32, final locking is arranged in the rotatingshaft 6 of this rotating shaft through hole 32.
Subsequently, this hubcap 5 is placed in this end cap straight hole 42, on this rotatingshaft 6, also there is locking nut hole 61, by screw, pass this locking hole 51 and be screwed in this locking nut hole 61, thereby further by this gland dish 4 and these gear disk 3 lockings.
With respect to prior art, because the utility model comprises the clamping boss 33 that is positioned at the taper on gear disk 3, the boss fixed hole 41 that comprises the taper matching with this clamping boss 33 on this gland dish 4, this boss fixed hole 41 forms tapered sleeve locking mechanism with this clamping boss 33, when a plurality of screws fix this gear disk 3 with these gland dish 4 interference fit, this tapered sleeve locking mechanism has guaranteed the close contact of this rotatingshaft 6 and this gear disk 3, has guaranteed the moment transmission between rotatingshaft 6 and this gear disk 3.And; such structure makes to have realized and having flexibly connected between string China ink, Chuan Shui mechanism and the main transfer mechanism of printing equipment; the in the situation that of equipment high speed stop, significantly reduction is resolved paper and is twined the impact that glue causes main drive gear, has played the protective action to main drive gear.
It should be noted that, above embodiment is only unrestricted in order to the technical solution of the utility model to be described, although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify or be equal to replacement the technical solution of the utility model, and not departing from the spirit and scope of technical solutions of the utility model, it all should be encompassed in the middle of claim scope of the present utility model.
