Description
Technical field
Step speed changer of the present invention is specifically related to a kind of planetary transmission.
Background technique
Along with the development of electric motor car industry, the motor demand constantly increases, and the drawback that electric motor car can not the conversion gear displays is also more and more; As: the electric motor car climbing is unable; Burn out motor easily, can not embody speed when unloaded, based on this; Many manufacturers have developed the box speed changer of many moneys, and box speed changer structure is complicated, volume is big, higher, the difficult installation of cost.
Summary of the invention
The objective of the invention is to: a kind of planetary transmission is provided, and this speed changer structure is simple, and advantages of small volume is with low cost, and is easy for installation.
Technical solution of the present invention is: bull gear, little gear ring, input shaft, output shaft, mafor planet gear, small planetary gear, planet carrier, planet pin, large sun gear, Sunny gear are installed in the cabinet of being made up of casing and case lid are constituted planetary transmission; On the inwall of casing, pass through the decorative pearl on top of an official cap, jackscrew fixedly bull gear and little gear ring; At least three grooves distribute on the outer wall of bull gear and little gear ring; The decorative pearl on top of an official cap withstands on large and small gear ring can only forward be slided on cabinet wall; Bull gear and little gear ring are linked together by the speed governing pull bar, and the speed governing pull bar passes case lid, at an end of casing input shaft are installed; The large sun gear of the different teeth of coaxial installation and Sunny gear on the input shaft; The other end at casing passes through the Bearing Installation output shaft, connects planet carrier on the output shaft in the casing, passes through at least three pairs of mafor planet gears of the coaxial installation of planet pin and small planetary gear on the planet carrier; Mafor planet gear engagement Sunny gear and little gear ring, small planetary gear engagement large sun gear and bull gear.
When the needs transmission, pulling speed governing pull bar makes one group of mafor planet gear of little gear ring interlock; Mafor planet gear revolves round the sun on little gear ring, and one group of small planetary gear is done driven rotation, when mafor planet gear revolves round the sun on little gear ring; Mafor planet gear drives planet carrier and rotates, and rotates thereby drive output shaft; Otherwise, push back the speed governing pull bar, make one group of small planetary gear of bull gear interlock; Small planetary gear revolves round the sun on bull gear, and one group of mafor planet gear is done driven rotation, when small planetary gear revolves round the sun on bull gear; Small planetary gear drives planet carrier and rotates, and rotates thereby drive output shaft; Because big or small planetary velocity ratio is different, output shaft just obtains speed change.
The input shaft of speed changer of the present invention and direct coaxial connection of motor obtain speed changes through two groups of planetary gear train, also can parallelly connected four-speed gear shift, and simple in structure, advantages of small volume, with low cost, easy for installation.
Description of drawings
Fig. 1 is a structural representation of the present invention
Fig. 2 is that the A-A of Fig. 1 is to cut-away view
Among the figure: 1 casing, 2 jackscrews, 3 decorative pearls on top of an official cap, 4 bull gears, 5 speed governing pull bars, 6 case lids, 7 input shafts, 8 mafor planet gears, 9 small planetary gears, 10 large sun gears, 11 Sunny gears, 12 little gear rings, 13 planet carriers, 14 output shafts, 15 bearings, 16 planet pins.
Embodiment
Like Fig. 1, shown in 2; Installation bull gear 4, little gear ring 12, input shaft 7, output shaft 14, mafor planet gear 8, small planetary gear 9, planet carrier 13, planet pin 16, large sun gear 10, Sunny gear 11 constitute planetary transmission in the cabinet of being made up of casing 1 and case lid 6; On the inwall of casing 1, pass through the decorative pearl on top of an official cap 3, jackscrew 2 fixedly bull gear 4 and little gear ring 12; At least three grooves of distribution on the outer wall of bull gear 4 and little gear ring 12, the decorative pearl on top of an official cap 3 withstands on large and small gear ring 4,12 can only forward be slided on casing 1 inwall, and bull gear 4 is linked together by speed governing pull bar 5 with little gear ring 12; Speed governing pull bar 5 passes case lid 6; End at casing 1 is installed input shaft 7, and the large sun gear 10 and Sunny gear 11 of the different teeth of coaxial installation on the input shaft 7 are installed output shaft 14 at the other end of casing 1 through bearing 15; Connect planet carrier 13 on the output shaft 14 in the casing 1; Through at least three pairs of mafor planet gears of planet pin 16 coaxial installations 8 and small planetary gear 9, mafor planet gear 8 meshes Sunny gears 11 and little gear rings 12 on the planet carrier 13, small planetary gear 9 engagement large sun gears 10 and bull gear 4.
When the needs transmission; Pulling speed governing pull bar 5 makes one group of mafor planet gear 8 of little gear ring 12 interlocks, and mafor planet gear 8 revolves round the sun on little gear ring 12; One group of small planetary gear 9 is done driven rotation; When mafor planet gear 8 revolved round the sun on little gear ring 12, mafor planet gear 8 drove planet carrier 13 and rotates, and rotated thereby drive output shaft 14; Otherwise; Push back speed governing pull bar 5, make one group of small planetary gear 9 of bull gear 4 interlocks, small planetary gear 9 revolves round the sun on bull gear 4; One group of mafor planet gear 8 is done driven rotation; When small planetary gear 9 revolved round the sun on bull gear 4, small planetary gear 9 drove planet carrier 13 and rotates, and rotated thereby drive output shaft 14; Because the velocity ratio of big small planetary gear 8,9 is different, output shaft 14 just obtains speed change.
