Abstract
The utility model relates to a dense-type motor speed reduction mechanism belonging to a technical field of motor production. The utility model includes a worm which is connected with an outlet shaft of motor; the worm is provided with a spiral tooth with single rotation direction. The same side of the worm is provided with two combined gears; each combined gear includes a coaxially arranged worm part and a gear part; the worm parts of two combined gears are engaged with the worm at the same time; the gear parts of the two combined gears are engaged with the output gear at the same time. The utility model has 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 compact(ing) machine 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 compact structure, 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 that links to each other with Motor Shaft, described worm screw is provided with the helical tooth of single rotation direction, the same side of worm screw is provided with two built-up gears, each built-up gear comprises the worm gear part and the gear parts of coaxial setting, the worm gear part while and the worm meshing of two built-up gears, the gear parts of two built-up gears meshes with output gear simultaneously.Two at the same level decelerations of identical built-up gear 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 the axis of described output gear and two built-up gears lays respectively at the both sides of worm screw.The both sides that two built-up gears and output gear are separately positioned on worm screw can make their distribution more even, and structure is compact more.
As preferably, the worm gear of described built-up gear part and gear parts 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 compact structure, 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 same side of worm screw 1 is provided with two built-up gears 2, each built-up gear 2 comprises the worm gear part 3 and the gear parts 4 of coaxial setting, worm gear part 3 and gear parts 4 are the one injection structure, the worm gear part 3 of two built-up gears 2 meshes with worm screw 1 simultaneously, the gear parts 4 of two built-up gears 2 simultaneously and output gear 5 engagements, output gear 5 and two built-up gears 2 lay respectively at the both sides of worm screw.
