Abstract
Present invention relates to a high transformation ratio single stage planetary reduction gear, which has compact conformation, small size, good dynamic property and is suitable for making high performance, high efficiency electrically driven vehicle (electrical driving bicycle, electric motor cycle, electric automobile, electrical driving wheelchair etc).Said invention also can be used as common speed reducer.
Description
Retarder is the core component of electric vehicle, and whether the advanced person will directly have influence on further developing of electric vehicle to its performance.The present invention relates to a kind of high variable speed ratio single-stage planetary reduction gear, this reducer structure compactness, size is little, dynamic property good, is particularly suitable for making high-performance, high efficiency motor vehicle (electric bicycle, battery-operated motor cycle, electric vehicle, electric wheelchair etc.).Also can be used as common retarder uses.
Technological scheme of the present invention is:
The central shaft of retarder is divided into two sections, i.e. left side axle (1) and right axle (7).On left side axle (1), be fixed with bearing (11), (12), (13), the gear of left side axle (1) and the engagement of the gearwheel of turriform planetary pinion (2), the small gear of turriform planetary pinion (2) and imperial palace garden gear (5) engagement, the outer rim of imperial palace garden gear (5) is fixedlyed connected with the inner edge of retarder shell (8), turriform planetary pinion (2) and bearing (3), (6) connect, bearing (3) is connected with planetary carrier end cap (4), bearing (6) is connected with right axle (7), right axle (7) is supported on bearing (9) and (11), bearing (9) is supported on the retarder shell (8), the interior cover of bearing (11) is connected with left side axle (1), planetary carrier end cap (4) is connected with right axle (7) by bolt (10), bearing (12), (13) be connected with retarder end cap (14), retarder end cap (14) is connected with retarder shell (8).
Its planetary carrier is formed by connecting by bolt (10) by planetary carrier end cap (4), right axle (7).
In planetary reducer, designed turriform planetary pinion (2), the gear engagement of the gearwheel of turriform planetary pinion (2) and left side axle (1), the small gear of turriform gear (2) meshes with big garden internal gear (5).
Owing to designed the turriform planetary pinion, make the radial dimension of retarder of the present invention dwindle greatly, this measure can improve the specific power and the rigidity of retarder greatly.
The present invention has the following advantages:
1) simple in structure, reliability is high.
2) size is little, no-load voltage ratio is big.
3) the efficient height, output torque big.
Further specify specific structural features of the present invention and usage mode below in conjunction with Figure of description and embodiment.
Brief Description Of Drawings:
Fig. 1 is the overall erection drawing of a kind of high variable speed ratio single-stage planetary reduction gear of the present invention.(1) among Fig. 1 is a left side axle, (2) be the turriform planetary pinion, (3) are bearings, and (4) are the planetary carrier end caps, (5) be imperial palace garden gear, (6) be bearing, (7) are right axles, and (8) are the retarder shells, (9) be bearing, (10) be bolt, (11), (12), (13) are bearings, and (14) are the retarder end caps.
Specific structural features of the present invention is: the central shaft of retarder is divided into two sections, i.e. left side axle (1) and right axle (7).On left side axle (1), be fixed with bearing (11), (12), (13), the gear of left side axle (1) and the engagement of the gearwheel of turriform planetary pinion (2), the small gear of turriform planetary pinion (2) and imperial palace garden gear (5) engagement, the outer rim of imperial palace garden gear (5) is fixedlyed connected with the inner edge of retarder shell (8), turriform planetary pinion (2) and bearing (3), (6) connect, bearing (3) is connected with planetary carrier end cap (4), bearing (6) is connected with right axle (7), right axle (7) is supported on bearing (9) and (11), bearing (9) is supported on the retarder shell (8), the interior cover of bearing (11) is connected with left side axle (1), planetary carrier end cap (4) is connected with right axle (7) by bolt (10), bearing (12), (13) be connected with retarder end cap (14), retarder end cap (14) is connected with retarder shell (8).
Its planetary carrier is formed by connecting by bolt (10) by planetary carrier end cap (4), right axle (7).
In planetary reducer, designed turriform planetary pinion (2), the gear engagement of the gearwheel of turriform planetary pinion (2) and left side axle (1), the small gear of turriform gear (2) meshes with big garden internal gear (5).
Usage mode of the present invention has three kinds:
1, when retarder uses, the motive force input shaft is connected with left side axle (1), then right axle (7) the output slow-speed of revolution, high pulling torque;
2, when speed increaser uses, the motive force input shaft is connected with right axle (7), then left side axle (1) is exported high rotating speed, little moment of torsion;
3, when electric wheel hub uses, the motive force input shaft is connected with left side axle (1) and right side axle (7) is fixing, then retarder shell (8) rotation and export the slow-speed of revolution, high pulling torque.
