Abstract
A helical tooth planet doubling mechanism comprises a sun gear, an epicyclic gear, a geared ring, a connecting sleeve, an arresting disc, a high and a low gear outer cone rings, a synchronizer assembly, an epicyclic frame and the like, wherein the connecting sleeve is connected with the geared ring through a large-end and is connected with a fluted disc of the synchronizer assembly through a small-end, the low gear outer cone ring is connected with the arresting disc, a locating lug boss of the arresting disc is connected with the shell of a variable-speed device, the high gear outer cone ring is sleeved on an output shaft, when a geared ring of a synchronizer moves to left and is engaged with the low gear outer cone ring, the geared ring and the shell of a variable-speed device are connected and without rotating, the planetary gear train is in low gear, when the geared ring of the synchronizer moves to right and is engaged with the high gear outer cone ring, the geared ring and the output shaft rotate together, namely, the geared ring is synchronized with the epicyclic frame, wherein the velocity ratio between the sun gear and the epicyclic frame is 1 : 1, namely the velocity ratio is in high gear. The sun gear, the epicyclic gear and the geared ring adopt the helical tooth, and the helical tooth planet doubling mechanism has the advantages of big coincidence coefficient, compact structure, strong carrying power, small impact, smooth transmission and low noise, and the two velocity ratio output enables the velocity ratio of the variable-speed device to increase twice.
Description
Technical field
The utility model relates to a kind of gear that is contained in the automotive transmission rear end, is specifically related to a kind of helical teeth planet times gear mechanism.
Background technique
At present, straight-tooth planetary pinion transmission group is often adopted in the design of speed changer both at home and abroad, and transmission is steady inadequately, and rotational noise is big, and bearing capacity is strong inadequately.
The model utility content
In order to address the above problem, the purpose of this utility model is to provide a kind of helical teeth planet times gear mechanism, and gear teeth overlap coefficient is big, compact structure, bearing capacity is strong, impact little, stable drive, noise is low, the output of two kinds of speed ratios makes the speed ratio of speed changer double.
The helical teeth planet times gear mechanism that provides according to the utility model, it comprises the sun gear that connects output shaft, be fixed on the planetary pinion on the planet wheel shaft, gear ring with the planetary pinion engagement, the connecting sleeve that big end is connected with gear ring, connecting sleeve connects the fluted disc of synchronizer assembly by small end, the fluted disc of synchronizer assembly connects the outer conical ring of high and low shift by the synchronizer gear ring, low-grade outer conical ring is connected with arresting disc by spline, the positioning boss on the arresting disc and the housing of speed changer link together, high-grade outer conical ring by spline package on output shaft.
Above-mentioned sun gear, planetary pinion and gear ring are the helical teeth meshing engagement structure.
The helical teeth planet times gear mechanism that the utility model provides, sun gear, planet wheel, gear ring are helical teeth, and because several planetary pinions are arranged, power is shunted simultaneously, so bearing capacity is strong, stable drive, rotational noise is low, can do mechanism compacter.When synchronizer during respectively to left and right putting into gear, two kinds of speed ratios outputs make the speed ratio output of speed changer double.
Below with reference to accompanying drawings preferred implementation of the present utility model is done to describe in further detail.
Description of drawings
Fig. 1 is the structural drawing of the utility model helical teeth planet times gear mechanism.
Embodiment
Referring to Fig. 1, Fig. 1 has represented the helical teeth planet times gear mechanism of the utility model preferred implementation, mainly is made up of sun gear (on the speed changer two) 10, planet wheel shaft 1, planetary pinion 2, gear ring 3, connecting sleeve 9, arresting disc 4, the outer conical ring 5,7 of high and low shift, synchronizer assembly 6, planet carrier (output shaft) 8.Connecting sleeve 9 is connected with gear ring 3 by the spline of big end, be connected by the fluted disc of small end with the synchronizer assembly, low-grade outer conical ring 5 is connected with arresting disc 4 by spline, and the positioning boss on the arresting disc 4 and the housing of speed changer link together, the outer conical ring of top grade 7 by spline package on output shaft.
Concrete working method is as follows:
When the gear ring of synchronizer is moved to the left when meshing with low-grade outer conical ring 5, gear ring 3 links together with case of transmission by the outer conical ring 5-of the gear ring-low grade arresting disc 4 of the fluted disc-synchronizer of connecting sleeve 9-synchronizer assembly, gear ring does not rotate (not rotating with the rotation of sun gear 10), this moment, planetary gear train was deceleration, and is promptly low-grade.
When the gear ring of synchronizer moves right and meshes with high-grade outer conical ring 7, gear ring 3 links together with output shaft (planet carrier) 8 by the outer conical ring 7 of the gear ring-top grade of the fluted disc-synchronizer of connecting sleeve 9-synchronizer assembly, promptly when sun gear rotates, gear ring and planet carrier rotate synchronously, speed ratio between sun gear and the planet carrier (output shaft) is 1: 1 at this moment, and is promptly high-grade.
This planetary mechanism is loaded on the rear end of speed changer, two sun gears of speed changer as this mechanism, and two kinds of speed ratio outputs by this planetary mechanism make the speed ratio of speed changer double.
Because sun gear, planet wheel, gear ring are helical teeth, because several planetary pinions are arranged, power is shunted simultaneously, so bearing capacity is strong, and stable drive, rotational noise is low, and can do mechanism compacter.
Although above the specific embodiment of the present invention is described, but this only is exemplary, those skilled in the art can figure out: in claims institute restricted portion, multiple other mode of execution can also be arranged, and all based on the mode of execution of design philosophy of the present invention all within the scope of the invention.
