Abstract
The invention discloses a gear transmission device, which comprises a driving motor, an input gear, three step-shaped intermediate gears and an output gear. The input gear is installed on the driving motor. The input gear is simultaneously engaged with the larger ends of the three step-shaped intermediate gears in an external engagement transmission way to form a first-stage transmission. The three step-shaped intermediate gears are uniformly distributed around the input gear. The output gear is simultaneously engaged with the smaller ends of the three step-shaped intermediate gears in the external engagement transmission way to form a second-stage transmission. The output gear is arranged among the three step-shaped intermediate gears. The axis of the output gear is overlapped with the axis of the input gear. The axes of the three step-shaped intermediate gears are in parallel with the axes of the input gear and the output gear. Compared with a traditional gear transmission structure, the gear transmission device disclosed by the invention has the advantages that the size in the circumferential direction is comparatively balanced, the overall structure is compact, and the size is smaller and the structure is more compact under the situation that the same torque is transmitted.
Description
Technical field
The present invention relates to automobile manufacturing field, particularly relate to a kind of gear drive.
Background technique
In traditional two-stage external gear pump drive mechanism, three gears are arranged generally: an input gear, middle gear and the output gear of connecting.Normally outer gearing mode.If input axis and output axis coaxial line, the size of driving mechanism on single direction can be very outstanding so, and be unbalanced in a circumferential direction, and the space that occupies is also bigger.Each grade transmission engagement all is that a pair of gear is meshing, and all transmission power all concentrates on the single gear, and is very high to intensity and the endurance quality requirement of tooth.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of gear drive and transmits same torque with conventional gears drive mechanism phase specific energy, and size in a circumferential direction is relatively more balanced, and it is little to take up space, compact overall structure.
For solving the problems of the technologies described above gear drive of the present invention, comprising: input gear, three stepped shaft intermediate gears and an output gear, the input gear is installed on the drive motor;
The bigger end of input gear while and three stepped shaft intermediate gears adopts the engagement of the outer gearing kind of drive as first order transmission, and three stepped shaft intermediate gears are distributed on around the input gear;
Meshing as second level transmission than the small end employing outer gearing kind of drive of output gear while and three stepped shaft intermediate gears, output gear is positioned at the centre of three stepped shaft intermediate gears, the dead in line of the axis of output gear and input gear;
Three stepped shaft intermediate gears, its bigger end is different with less end tooth number, its big end tooth number and input gear number of teeth coupling, its less end tooth number and output gear number of teeth coupling, its axis is parallel with the axis of input, output gear.
The size that gear drive of the present invention is compared with the conventional gears drive mechanism in a circumferential direction is relatively more balanced, it is little to take up space, can make automobile with general execution device do littler, better adapt to vehicle installing space demand, under the situation of transmitting same torque, littler, the more compact structure of size.

Embodiment
As shown in Figure 1 and Figure 2, gear drive of the present invention comprises: input gear 2, three stepped shaft intermediate gears 5 and an output gear 8, and input gear 2 is installed on the drive motor 1;
The bigger end 10 of 2 whiles of input gear and three stepped shaft intermediate gears adopts the engagement of the outer gearing kinds of drive as first order transmission, and three stepped shaft intermediate gears 5 are distributed on around the input gear 2;
Meshing as second level transmission than the small end 11 employing outer gearing kinds of drive of 8 whiles of output gear and three stepped shaft intermediate gears, output gear 8 is positioned at the centre of three stepped shaft intermediate gears 5, three stepped shaft intermediate gears than small end 11 be distributed on output gear 8 around, the axis of output gear 2 and the input gear 8 dead in line;
Three stepped shaft intermediate gears 5, its bigger end 10 are with different than small end 11 numbers of teeth, and its bigger end 10 numbers of teeth are mated with input gear 2 numbers of teeth, and it is than small end 11 numbers of teeth and output gear 8 numbers of teeth coupling, and its axis is parallel with the axis of input, output gear.
As shown in Figure 3, input gear 2 is installed on the drive motor 1, and drive motor 1 integral installation and is fixed on the electric machine casing 3 by motor metal blanking cover 4 on electric machine casing 3.Intermediate gear shaft 6 is installed on the electric machine casing 3, is used for supporting the rotation of intermediate gear 5.Three intermediate gears 5 are installed on the intermediate gear shaft 6 engagement of moving of back and input gear 2.Output gear 8 is installed on the terminal housing 7.After electric machine casing 3 and terminal housing 7 fit together, do not have relative movement each other after two housing installations, and output gear 8 is and intermediate gear 5 meshes together.The moment of torsion of drive motor 2 outputs will be delivered on the output gear shaft 9 by input gear 1, intermediate gear 5 and output gear 8, and moment of torsion is passed.Three intermediate gears all are to participate in simultaneously in the process of engagement in the process of motion, and the moment of torsion of drive motor 2 outputs will be divided into three parts and share on the intermediate gear 5, and three intermediate gears 5 pass to output gear 8 simultaneously with moment of torsion again.In the process of engagement, input gear 1 is that three teeth are worked at the same time, and intermediate gear 5 and output gear 8 also are all to be that three teeth are worked at the same time.Under the situation of transmitting identical moment of torsion, the power that each grade gear bears will be littler.
Below through the specific embodiment and the embodiment the present invention is had been described in detail, but these are not to be construed as limiting the invention.Under the situation that does not break away from the principle of the invention, those skilled in the art also can make many distortion and improvement, and these also should be considered as protection scope of the present invention.
