Abstract
The utility model discloses a kind of light-duty planetary reduction gear box, including input casing, input shaft gear, bevel gear wheel, middle adpting flange, planetary mechanism, output end casing and output flange axle；Installation input shaft gear and bevel gear wheel in input casing；Installation output flange axle in output end casing；Input shaft gear and bevel gear wheel composition straight bevel gear pair, straight bevel gear pair is first order reducing gear, and is connected with planetary mechanism, while realizes 90 ° of angle transmissions to change transmission direction；Planetary mechanism and output flange axis connection.The utility model simplifies the drive mechanism of input, and intensity and manufacturing cost have been taken into account under the operating mode of small torque applications；The power source for adapting to different rotation directions improves the applicability of gear-box.
Description
Technical field
The utility model belongs to planetary reduction gear box technical field, and in particular to a kind of light-duty planetary reduction gear box.
Background technology
Light-duty planetary reduction gear box, industrial or agricultural Mixing Machine and engineering machinery are mainly used in, it is a kind of high efficiency
Type.Conventional type can not be realized lightweight, can not simultaneously be taken into account and be manufactured into while proof strength due to reasons in structure
This.The utility model is correspondingly improved with regard to disadvantages mentioned above.
The content of the invention
The purpose of this utility model is in view of the above-mentioned problems, providing a kind of light-duty planetary reduction gear box, its design structure
Compact, overall weight is lighter.
The utility model adopted the following technical scheme that to realize, a kind of light-duty planetary reduction gear box, it is characterised in that：
Mainly include input casing, input shaft gear, bevel gear wheel, middle adpting flange, planetary mechanism, output end casing and output
Flange shaft；Installation input shaft gear and bevel gear wheel in input casing；Installation output flange axle in output end casing；Input shaft
Gear and bevel gear wheel composition straight bevel gear pair, straight bevel gear pair is first order reducing gear, and is connected with planetary mechanism,
90 ° of angle transmissions are realized simultaneously to change transmission direction；Planetary mechanism is second level reducing gear, and with output flange axis connection.
Further, above-mentioned light-duty planetary reduction gear box, it is characterised in that：Described input shaft gear is small bevel gear
Wheel merges the integrative-structure to be formed with input shaft.
Straight bevel gear pair is arranged at speed end, is first order reducing gear, and planetary mechanism is in final reduction mechanism.
It is of the present utility model to have the technical effect that：Power is transferred to auger tooth by the left end of input shaft gear first during use
Wheel, straight bevel gear pair realize that the first order is slowed down；Now moment of torsion obtains is lifted for the first time, while realizes 90 ° of angle transmissions to change
Become transmission direction.Power is transferred to planetary mechanism by straight bevel gear pair again, and planetary mechanism plays a part of second level deceleration, turned round
Square, which is got back, to be substantially improved.Power is transferred to output flange axle by last planetary mechanism again, output flange axle do not change speed and
Direction, the only moment of torsion to outside equivalent output planetary mechanism output.
The utility model has the advantages that：Straight bevel gear is secondary to realize that and can while increasing torsion and change transmission direction of slowing down is fitted
The power source of two kinds of different rotation directions clockwise and anticlockwise is answered, so as to improve the applicability of gear-box.Bevel gear and input shaft
The design being integrated not only had taken into account the strength of gear teeth under the operating mode of small torque applications but also had reduced manufacturing cost.Gear Planet Transmission is adopted
With floating load balancing mechanism, load inequality coefficient is small between planetary gear, and effect of load balancing mechanism is notable.Planetary mechanism power density is big, small volume.
Brief description of the drawings
Fig. 1 is overall structure diagram of the present utility model.
Fig. 2 is Fig. 1 partial enlarged drawing.
In figure, 1. input casings, 2. input shaft gears, 3. bevel gear wheels, 4. middle adpting flanges, 5. planet machines
Structure, 6. output end casings, 7. output flange axles.
Embodiment
As shown in Figure 1 and Figure 2, a kind of light-duty planetary reduction gear box, gear case body use closed type structure, mainly included
Input casing 1, middle adpting flange 4 and output end casing 6.Mainly comprising input shaft gear 2, auger in input casing 1
Gear 3, power input from the left end of input shaft gear 2.In output end casing 6 mainly comprising output flange axle 7 and with planet machine
Structure 5 is connected.Input casing 1 is sequentially connected with middle adpting flange 4, planetary mechanism 5 and output end casing 6, described input
Shaft gear 2 is that bevel pinion merges the integrative-structure to be formed with input shaft.Input shaft gear 2 and bevel gear wheel 3 form straight-tooth cone
Gear pair, straight bevel gear pair is first order reducing gear, and is connected with planetary mechanism 5, while realizes 90 ° of angle transmissions to change
Transmission direction.Planetary mechanism 5 is second level reducing gear, and is connected with output flange axle 7.
Internal drive part connects as follows：Input shaft gear 2 connects bevel gear wheel 3, and bevel gear pair subtracts for the first order
Speed, while 90 ° of angle transmissions are realized to change transmission direction.Bevel gear wheel 3 is connected with planetary mechanism 5, and planetary mechanism 5 plays second
The effect that level is slowed down.Planetary mechanism 5 is connected with output flange axle 7 again.Output flange axle 7 is embedded in row by outer involute spline
In the planet carrier of star mechanism 5 in involute spline.
