Pressure driving speed reducing device is developed so far, although product structure has formed diversification.Hydraulic moving deceleration device brand completes
Seriation, but construction machinery industry enters extremely low state in recent years, occur in that production capacity surplus, market profit generally glide and
The phenomenons such as competition situation changes, in this case, enterprise must release the product being more close to the users.Present domestic life
The hydraulic moving deceleration device produced is substantially NGW type of belt drive planet circular system composition, sun gear and gear ring and uses floating structure,
The one-level Gear Planet Transmission with two grades is split, due to the split transmission of planetary gear, causes the volume of hydraulic moving deceleration device
Increasing, take up space, service life is short, causes processing to reduce with the precision installed, and manufacturing cost is the most of a relatively high.
Utility model content
This utility model is in order to make up the deficiencies in the prior art, it is provided that one is rational in infrastructure, volume is little, service life is long
Duplicate gear deceleration device.
For achieving the above object, this utility model employing following technical proposals: a kind of duplicate gear deceleration device, including shell
Body, one-level ring gear, planetary plate, duplicate gear, two grades of ring gears and connection gear；Described one-level ring gear is fixed on housing
On, the end of described housing is provided with end cap, and described planetary plate is installed on the output shaft of hydraulic motor by bearing, described duplex
Gear is installed on planetary plate, and described duplicate gear includes that a large diameter gear and a small-diameter gear, described connection gear are fixed on
On the shell of hydraulic motor, described two grades of ring gears are sheathed on connection gear and engage with being connected gear；Described duplicate gear
Large diameter gear engage with the driving tooth on hydraulic motor output shaft and one-level ring gear, the small-diameter gear of described duplicate gear with
Two grades of ring gear engagements.
Preferably, described connection gear is fixed in hydraulic motor shell by screw and straight pin.
Preferably, described housing and hydraulic motor shell are installed by bearing fit and the outside of bearing is provided with floating oil
Envelope.
Preferably, described two grades of ring gears coordinate installation by jump ring with being connected gear.
With improvement, described two grades of ring gears include two profile of tooth sections, two profile of tooth sections respectively be connected gear and duplex-gear
The small-diameter gear engagement of wheel.
Operation logic: hydraulic motor output shaft rotates and drives large diameter gear to rotate, now one-level ring gear and duplicate gear
Large diameter gear composition NGW type Planetary Gear Transmission, the small-diameter gear composition NGW type planet tooth of two grades of ring gears and duplicate gear
Wheel transmission；Due to large diameter gear and the small-diameter gear angular velocity phase of mass motion during Planetary Gear Transmission in duplicate gear
With and diameter is different, and two grades of ring gears with is connected gear and engages and do not rotate, therefore finally rotation is by the big footpath of duplicate gear
Gear passes to housing drive shell and rotates.
The beneficial effects of the utility model are: the feature of similar products at home and abroad is used for reference, integrated to this utility model, original
On the basis of planetary gear monomer, being designed to one, duplicate gear deceleration device is compared with conventional hydraulic driving speed reducing device
At least three aspect advantage: be 1. duplicate gear due to planetary gear, make deceleration inner chamber reduce, save portion supports, overall body
Long-pending reduction, plays energy-saving and cost-reducing purpose, and duplicate gear i.e. saving of labor in terms of machining with tooth Profile Machining can guarantee that again higher
Machining accuracy；2. compact conformation, volume is little, lightweight；3. stable movement, service life is long.

Detailed description of the invention
In order to be illustrated more clearly that this utility model embodiment or technical scheme of the prior art, below will be to embodiment
Or the required accompanying drawing used is briefly described in description of the prior art, it should be apparent that, the accompanying drawing in describing below is only
It is embodiments more of the present utility model, for those of ordinary skill in the art, before not paying creative work
Put, it is also possible to obtain other accompanying drawing according to these accompanying drawings.
A kind of duplicate gear deceleration device as shown in Fig. 1 to Fig. 2, including housing 1, one-level ring gear 2, planetary plate 3, double
Connection 4, two grades of ring gears 5 of gear and connection gear 6；One end cap 11 is secured by bolts on housing 1, OK with one-level ring gear 2
Astrolabe 3 is installed on the output shaft of hydraulic motor by bearing；Duplicate gear 4 is installed on planetary plate 3 by a rotating shaft, and wraps
Include large diameter gear 7 and the small-diameter gear 8 of 20 teeth of 20 octadentates；Connect gear 6 solid by screw and straight pin
