Abstract
The utility model relates to a high stability motor gear speed reduction mechanism belonging to the technical field of motor production. The utility model includes a worm which is connected with an outlet shaft of motor, and an output gear; the worm is provided with a spiral tooth with single rotation direction. The two sides of the worm are respectively provided with a left combined gear and a right combined gear; the left combined gear and the right combined gear respectively include a coaxially arranged worm part and a gear part; the worm parts of the left combined gear and the right combined gear have reverse rotation directions with each other and are engaged with the worm at the same time; the output gear is provided with an internal tooth ring; the gear parts of the left and right combined gears are engaged with the internal tooth ring of the output gear. The utility model has high running stability, dense structure, low production cost, long service life, can bear large load rotation moment, and has large speed reduction ratio.
Description
Technical field
The utility model relates to a kind of high stability motor gear reducing gear, belongs to the technical field that motor is produced.
Technical background
A kind of automotive seat of special secondary transmission is regulated motor (CN03251118.3), comprise electric machine assembly, cabinet, reach the worm screw that links to each other with the output shaft of electric machine assembly, on described worm screw, divide two sections the opposite helical tooth of rotation direction is set, the worm gear engagement driving that described two sections helical tooths are complementary with it respectively, and the coaxial gear that is provided with on described two worm gears respectively, described two gears all with the output gear engagement driving that is located in the cabinet.Be provided with two sections helical tooths that rotation direction is opposite on the worm screw of said structure, its difficulty of processing of the worm screw of this kind structure is much larger than the worm screw of single rotation direction, so its processing cost is also higher, and then has caused the raising of motor decelerating mechanism cost of production; Simultaneously, when two sections helical tooths of the different rotation directions of processing, two sections helical tooths need be provided with tool withdrawal groove respectively with the connecting part of intermediate location, and have caused worm screw intermediate location intensity relatively poor, rupture easily, and then influenced the working life of motor decelerating mechanism.
Summary of the invention
The utility model purpose is to provide a kind of transmission stability height, and cost of production is lower, and working life is longer, can bear the heavy load torque, and the compact(ing) machine reducing gear that reduction speed ratio is bigger has solved the problem that above-mentioned technology exists.
Above-mentioned technical purpose of the present utility model mainly solves by the following technical programs: comprise the worm screw and the output gear that link to each other with Motor Shaft, described worm screw is provided with the helical tooth of single rotation direction, the both sides of worm screw are respectively equipped with left built-up gear and right built-up gear, left side built-up gear and right built-up gear comprise the worm gear part and the gear parts of coaxial setting respectively, the worm gear part of left side built-up gear opposite also while and worm meshing with the worm gear part rotation direction of right built-up gear, described output gear is provided with ring gear, the gear parts while of left built-up gear and right built-up gear and the ring gear engagement of output gear.Two at the same level decelerations of built-up gear that lay respectively at the worm screw both sides are set between worm screw that links to each other with Motor Shaft and output gear, improved the stability of gearing down greatly, improved the ability of bearing load torque, simultaneously, because the worm screw that is connected with the electrode shaft is the worm screw of single rotation direction, therefore its difficulty of processing will be well below the worm screw of two sections helical tooths with different rotation directions with processing cost, thereby reduce the cost of production of reducing gear, also transferred to the end of worm screw simultaneously for the tool withdrawal groove of processing helical tooth, and improved the intensity of worm screw, prolonged working life of the present utility model.
As preferably, the axis of described output gear is between the axis of the axis of left built-up gear and right built-up gear.Wherein, the axis designs with output gear can make structure of the present utility model comparatively compact between left built-up gear and right built-up gear.
As preferably, the gear parts of described left built-up gear and right built-up gear and worm gear partly are the one injection structure.Adopt the built-up gear of one injection structure can make structure of the present utility model compact more on the one hand, can alleviate overall weight of the present utility model on the other hand.
Characteristics such as therefore, the utlity model has the transmission stability height, cost of production is lower, and working life is longer, can bear the heavy load torque, and reduction speed ratio is bigger.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model.
Embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment 1: as shown in Figure 1, the worm screw 1 that links to each other with Motor Shaft is provided with the helical tooth of single rotation direction, the both sides of worm screw 1 are respectively equipped with left built-up gear 2 and right built-up gear 3, left side built-up gear 2 comprises the worm gear part 21 and the gear parts 22 of coaxial setting, right built-up gear 3 comprises the worm gear part 31 and the gear parts 32 of coaxial setting, the gear parts and the worm gear of left side built-up gear 2 and right built-up gear 3 partly are the one injection structure, the worm gear part 21 of left side built-up gear 2 and while and worm screw 1 engagement opposite with worm gear part 31 rotation directions of right built-up gear 3,1 output gear 4 is provided with ring gear, the gear parts 21 of a left side built-up gear 2 and right built-up gear 3 and gear parts 31 simultaneously with the ring gear engagement of output gear 4, the axis of output gear 4 is between the axis of the axis of left built-up gear 2 and right built-up gear 3.
