Description

One shaft type two-stage multi gear planetary transmission
Technical field
The present invention relates to a kind of planetary reduction gears, are in particular a shaft type two-stage multi gear planetary transmissions.
Background technique
It is many that planetary transmission has that small in size, light-weight, compact-sized, transmitting power is big, bearing capacity is high etc. Advantage, but also have that structure is complicated, bonded block is more simultaneously, need many clutches to switch input and output, maintenance is also inconvenient, Although the planetary transmission structure of fixed input shaft is simple, no-load voltage ratio is limited, it is difficult to realize biggish no-load voltage ratio.
Summary of the invention
Present invention aim to provide a kind of shaft type two-stage multi gear planetary transmission being able to achieve compared with large velocity ratio.
The present invention adopts the following technical scheme:
An a kind of shaft type two-stage multi gear planetary transmission, including driving sun gear, bind lines star-wheel group, speedup planetary gear, Gear ring, planetary wheel carrier, fixed gear ring, brake band, driven sun gear, the first output shaft, the second output shaft, bearing, thrust bearing, Oil sealing, cabinet；
The driving sun gear is fixedly mounted on input shaft；
All planet carriers of the bind lines star-wheel group and speedup planetary gear are connected, and form the first output shaft；
The fixed gear ring is engaged with speedup planetary gear；
The speedup planetary gear is engaged with driven sun gear；
The driven sun gear is fixedly mounted on the second output shaft；
First output shaft and the second output shaft are concentric；
Optimization, the bind lines star-wheel group includes double-planetary gear group and planetary gear set, passes through brake band and gear ring Cooperation, can switch between the planetary gear of bind lines star-wheel group, provide including reverse gear and at a slow speed, quickly including it is multiple Gear；
Optimization, the both ends of the cabinet are provided with bearing block, and first output shaft and the second output shaft are supported on On the bearing for stating an end bearing block, input shaft is supported on the bearing of above-mentioned another end bearing block, the first coaxial output shaft and Second output shaft also passes through plane bearing and is supported on bearing block；
Further, oil sealing is provided on the outside of the bearing block.
The principle of the present invention is: forming multiple gears by driving sun gear and double-planetary gear group or planetary gear set First order speed change is controlled by brake band and is shifted gears, it is contemplated that and the gear ratio of fixed input shaft is restricted, after first order speed change, The driven sun gear of the speedup engaged with the planetary gear of fixed gear ring is set, the revolving speed Jing Guo first order speed change is passed through fixed gear ring Planetary gear and the cooperation of driven sun gear constitute second level speed change, the number of teeth for changing driven sun gear may be implemented speedup or subtracts Speed is exported by output shaft.
The present invention is realized second level speed change, is increased by the cooperation of the planetary gear and driven sun gear of fixed gear ring The slewing range of fixed input shaft planetary reduction gear, a gear can be increased by increasing by one group of planetary gear, and structure is opposite Simply.
Detailed description of the invention:
Attached drawing 1 is structural schematic diagram of the invention；
In figure, 1 it is the second output shaft, 2 is oil sealing, 3 is driven sun gear, 4 is bearing, 5 is speedup planetary gear, 6 is flat Spherical bearing, 7 be fixed gear ring, 8 be brake band, 9 be planetary gear, 10 be gear ring, 11 be driving sun gear, 12 be duplex planet Wheel, 13 be planetary wheel carrier, 14 be cabinet；
Specific embodiment:
