The utility model content:
The purpose of this utility model is exactly the deficiency that exists at prior art and a kind of minisize dc reducing motor gearbox is provided, and has transmission efficiency height, long service life, energy-conservation characteristics.
To achieve these goals, the technical solution adopted in the utility model is:
Minisize dc reducing motor gearbox, include casing, rotate output shaft, the cover be arranged in the casing be pressed in output gear on the output shaft, with output gear meshed gears group, gear train includes a plurality of sub-assemblies of meshed gears successively, a plurality of rotation is arranged on the gear shaft in the casing, each gear train component overlaps respectively and is pressed on the gear shaft, and the two ends of each gear shaft are rotatably connected on the casing by oiliness bearing respectively.
Described gear shaft is provided with knurled surface.
Described output shaft is rotatably connected on the casing by oiliness bearing respectively.
Described gear train component and gear shaft are respectively 3.
Described casing includes front plate and the rear plate that parallel interval is provided with, and is fixedly connected by cylinder between front plate and the rear plate.
Described front plate and rear plate are circular configuration.
Described oiliness bearing pressing and fixing is on casing.
The utility model beneficial effect is: the utility model minisize dc reducing motor gearbox, include casing, rotation is arranged on the output shaft in the casing, cover is pressed in the output gear on the output shaft, with output gear meshed gears group, gear train includes a plurality of sub-assemblies of meshed gears successively, a plurality of rotations are arranged on the gear shaft in the casing, each gear train component overlaps respectively and is pressed on the gear shaft, the two ends of each gear shaft are rotatably connected on the casing by oiliness bearing respectively, oiliness bearing plays the effect of oilgear axle at gearbox, motor is in operation process, gear shaft rotates in oiliness bearing, can prevent to kill phenomenon like this, prolong the useful life of complete machine, gear shaft rotates the resistance of can reducing friction in oiliness bearing simultaneously, thereby improved transmission efficiency, energy-conservation.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is an end view of the present utility model.
Fig. 3 is the cutaway view of A-A direction among Fig. 2.
Embodiment:
Below in conjunction with accompanying drawing the utility model is further described, see shown in Fig. 1 to 3, minisize dc reducing motor gearbox, it includes casing 1, rotation is arranged on the output shaft 2 in the casing 1, cover is pressed in the output gear 3 on the output shaft 2, with output gear 3 meshed gears groups, gear train includes a plurality of sub-assemblies of meshed gears successively 4, a plurality of rotations are arranged on the gear shaft 5 in the casing 1, gear train component 4 and gear shaft 5 are respectively 3 in the present embodiment, each gear train component 4 overlaps respectively and is pressed on the gear shaft 5, the two ends of each gear shaft 5 are rotatably connected on the casing 1 by oiliness bearing 6 respectively, oiliness bearing 6 plays the effect of oilgear axle 5 at gearbox, and gear shaft 5 just can the smooth and easy rotation in oiliness bearing 6 with the transmission of gear train component 4.
Motor is in operation process, and gear shaft 5 rotates in oiliness bearing 6, can prevent to kill phenomenon like this, prolongs the useful life of complete machine, the resistance of can reducing friction of gear shaft 5 rotation in oiliness bearing 6 simultaneously, thus improved transmission efficiency, energy-conservation.
Certainly, the above only is preferred embodiment of the present utility model, so all equivalences of doing according to the described structure of the utility model patent claim, feature and principle change or modify, is included in the utility model patent claim.
