Abstract
The utility model provides a kind of two-stage gear hub reduction gear structure, and the reducer structure includes main shaft, sedan-chair shell, back casing, gear ring, sun gear, planet carrier, planetary gear, procapsid；The main shaft is installed with sedan-chair shell close to end, installs rack gear on the sedan-chair shell end；Back casing has been bolted outside the sedan-chair shell；The spindle nose is connected with sun gear, which is planet carrier；The planetary gear using planet carrier as axis connection is installed on the planet carrier；The procapsid is wrapped in sun gear, planet carrier, outside planetary gear, is fastened by bolts between the front housing and the rear housing；The structure realizes the deceleration transmission of large transmission ratio, reduces the transmission ratio of level-one main reducing gear, so that entire drive axle structure is more compact.
Description
Technical field
The utility model relates to technical field of mechanical transmission more particularly to a kind of two-stage gear hub reduction gear structures.
Background technique
Currently, hub reduction gear mainly has two major classes, one kind is cone planetary gear formula hub reduction gear, but uses wheel
The structure size of entire drive axle does not vary widely after side reducer, influences vehicle passability；Another kind of is cylinder row
The transmission ratio concentrated on central main reducing gear is distributed to hub reduction gear, subtracted to a certain extent by star gear hub reduction gear
The small size of main reducing gear, but in the case where hub for vehicle wheel installation site is certain, the transmission ratio of hub reduction gear distribution is not
It can guarantee the reasonable distribution of resultant gear ratio.
Utility model content
The purpose of this utility model is that it is in view of the drawbacks of the prior art and insufficient, a kind of two-stage gear hub reduction is provided
Device structure, which realizes the deceleration transmission of large transmission ratio, reduces the transmission ratio of level-one main reducing gear, so that entire drive axle knot
Structure is more compact.
A kind of two-stage gear hub reduction gear structure that in order to achieve the above purposes, the technical solution adopted by the utility model is:,
The reducer structure includes main shaft, sedan-chair shell, back casing, gear ring, sun gear, planet carrier, planetary gear, procapsid；The master
Axis is installed with sedan-chair shell close to end, installs rack gear on the sedan-chair shell end；Back casing has been bolted outside the sedan-chair shell；
The spindle nose is connected with sun gear, which is planet carrier；It is installed on the planet carrier using planet carrier as axis
The planetary gear of connection；The procapsid is wrapped in sun gear, planet carrier, outside planetary gear, passes through between the front housing and the rear housing
Bolt fastening.
Preferably, the gear ring is fixed on back casing by locking nut.
Preferably, tapered roller bearing is installed between the planet carrier and planetary gear, between the bearing and procapsid
It is installed with sleeve.
The beneficial effects of the utility model are: the structure realizes the deceleration transmission of large transmission ratio, reduces level-one main reducing gear
Transmission ratio so that entire drive axle structure is more compact.
Detailed description of the invention
Attached drawing described herein is to be used to provide a further understanding of the present invention, and constitutes one of the application
Point, but do not constitute the restriction to the utility model.
Fig. 1 is reducer structure schematic diagram.
Wherein: 1 is main shaft, and 2 be sedan-chair shell, and 3 be back casing, and 4 be gear ring, and 5 be sun gear, and 6 be planet carrier, and 7 be planetary gear,
8 be procapsid.
Specific embodiment
In conjunction with attached drawing, the utility model is described in further detail.
As shown, a kind of two-stage gear hub reduction gear structure, the reducer structure include main shaft 1, sedan-chair shell 2,
Back casing 3, gear ring 4, sun gear 5, planet carrier 6, planetary gear 7, procapsid 8；The main shaft 1 is installed with sedan-chair shell 2 close to end,
Rack gear 4 is installed on 2 end of sedan-chair shell；Back casing 3 has been bolted outside the sedan-chair shell 2；1 end of main shaft is connected with
Sun gear 5,5 two sides of sun gear are planet carrier 6；The planetary gear 7 with planet carrier 6 for axis connection is installed on the planet carrier 6；
The procapsid 8 is wrapped in sun gear 5, planet carrier 6, outside planetary gear 7, tight by bolt between the procapsid 8 and back casing 3
Gu.
In specific implementation, the gear ring 4 is fixed on back casing 3 by locking nut.
In specific implementation, it is installed with tapered roller bearing between the planet carrier 6 and planetary gear 7, the bearing and procapsid 8
Between be installed with sleeve.
When it is implemented, being equipped with 3 two-stage planet wheels 7 between sun gear 5 and gear ring 4, two-stage planet wheel 7 is in tradition
On the basis of simple planetary arrangement, planetary gear is changed to two-stage gear, i.e., a planetary gear is changed to coaxial left-right 2
A gear in different size engages 7 gear wheel of planetary gear with sun gear 5, planetary gear 7 to further increase transmission ratio
Pinion gear is engaged with gear ring 4.
