Abstract
The utility model discloses an increasing gear, include: planet drive gear group, planet drive gear group includes: power end planetary gear set and acceleration rate planetary gear set, the power end planetary gear set and the power input shaft of gear box mesh the transmission, and power end planetary gear set and the coaxial setting of acceleration rate planetary gear set set up the output shaft on acceleration rate planetary gear set's the sun gear wheel position, make acceleration rate planetary gear set drive the output shaft transmission of gear box. The utility model provides an increasing gear, through setting up the output shaft on the sun gear wheel position at acceleration rate planetary gear set, the sun gear drives through the meshing of the three planet pinion around the sun gear in the acceleration rate planetary gear set, reaches the driven purpose of output shaft that acceleration rate planetary gear set drove the gear box. Because sun gear does not wherein need the bearing to support, can realize higher rotation rate to guarantee increasing gear's output speed.
Description
Technical field
The utility model is related to technical field of mechanical transmission, more particularly to a kind of step-up gear.
Background technology
The output shaft of existing step-up gear generally needs to use bearings, using bearings, does not reach gear high
The purpose of speed rotation, the speed of output shaft will be affected, so as to limit the output speed of speed increasing gear.
Utility model content
To solve in the prior art, the output shaft that step-up gear is present uses bearings, causes output speed to be limited
Technical problem, the technical solution of the utility model is as follows：
Step-up gear in the utility model, including：Planet pinion group；The planet pinion group includes：
Power end planetary gearsets and speedup planetary gearsets；The power input shaft of the power end planetary gearsets and the gear-box
Engaged transmission, the power end planetary gearsets are coaxially disposed with the speedup planetary gearsets, the speedup planetary gearsets
Central gear position on output shaft is set, make the speedup planetary gearsets drive the output shaft of the gear-box to be driven.
In a preferred embodiment, the gear in the power end planetary gearsets is spur gear.
In a preferred embodiment, the gear in the speedup planetary gearsets is herringbone bear.
In a preferred embodiment, around the central gear and central gear in the power end planetary gearsets
Planet pinion gearratio be 5:2；Central gear in the speedup planetary gearsets and the planet around central gear
The gearratio of little gear is 4:1.
In a preferred embodiment, the planet in the power end planetary gearsets and speedup planetary gearsets is small
Gear is three.
Step-up gear in the utility model, compared with prior art, its advantage is：
Step-up gear in the utility model, by setting output on the central gear position of speedup planetary gearsets
Axle, central gear is to engage what is driven by three planet pinions around the central gear in speedup planetary gearsets, is reached
The purpose of the output shaft transmission of gear-box is driven to speedup planetary gearsets.Because central gear therein does not need bearing branch
Support, can realize rotary speed higher, so as to ensure the output speed of step-up gear.
Power end planetary gearsets and speedup planetary gearsets are intermeshed the speeders of connection equivalent to two, i.e., in fact
Two-stage speedup is showed, and because power end planetary gearsets are coaxially disposed with the speedup planetary gearsets, has installed and used non-
Often convenience, and gear-box volume will diminish, and will not take larger space.
Gear in power end planetary gearsets is spur gear, and the gear in speedup planetary gearsets is herringbone bear；Adopt
With double helical tooth and the combination speedup form of straight-tooth, there is no any axial force, stability enhancing.
Brief description of the drawings
Fig. 1 is the structural representation of step-up gear in the utility model.
Specific embodiment
Below in conjunction with accompanying drawing of the present utility model, the technical solution of the utility model is clearly and completely described.
Based on the embodiment in the utility model, what those of ordinary skill in the art were obtained under the premise of creative work is not made
Every other embodiment, belongs to the scope of the utility model protection.
As shown in figure 1, step-up gear, including：Planet pinion group；Planet pinion group includes：Power end row
Star gear train and speedup planetary gearsets；The engaged transmission of power input shaft 5 of power end planetary gearsets and gear-box, power end
Planetary gearsets are coaxially disposed with speedup planetary gearsets, and output shaft 1 is set on the central gear position of speedup planetary gearsets,
Speedup planetary gearsets are made to drive the output shaft 1 of gear-box to be driven.Gear in power end planetary gearsets is spur gear.Speedup
Gear in planetary gearsets is herringbone bear.
Wherein power end planetary gearsets include three small teeth of power end planet of power end central gear 3 and its surrounding
Wheel；Speedup planetary gearsets include three speedup end planet pinions 2 around speedup central gear and central gear.Power end
Planet pinion is connected by power transmission shaft 4 with speedup end planet pinion 2.Central gear 3 in power end planetary gearsets with
The gearratio of the planet pinion around central gear is 5:2；Central gear and central gear week in speedup planetary gearsets
The gearratio of the planet pinion 2 for enclosing is 4:1.Specific gear ratio determines according to service condition, realizes defeated from gear-box
Enter two grades of speedups of axle to gearbox output shaft.
The above, specific embodiment only of the present utility model, but protection domain of the present utility model do not limit to
In this, any one skilled in the art can readily occur in change in the technical scope that the utility model is disclosed
Or replace, should all cover within protection domain of the present utility model.Therefore, protection domain of the present utility model should be with the power
The protection domain that profit is required is defined.
