Summary of the invention
To be solved in the utility model is the problem that existing motor has only single-ended output, aims to provide the motor of a kind of two ends output, enriching the type of product, and satisfies some instructions for uses in special dimension.The technical scheme that addresses the above problem employing is: the motor of two ends output, comprise motor body, and it is characterized in that described motor body two ends are equipped with power transmission shaft and gear reduction box.
With the bag hired car is example, and its structure is the four-wheel vehicle normally, and preceding two-wheeled is a universal wheel, and back two-wheeled is the driving wheel that be arranged in parallel.Adopt prior motor, then must adopt the gear reduction box of eccentric output simultaneously, motor could be installed between two trailing wheels, thereby the gear reduction box size is bigger, installation difficulty is big, and is also very uneconomical.The motor of two ends of the present utility model output owing to adopt two ends output, can directly be installed on two trailing wheels on the output shaft of gear reduction box.Described gear reduction box can calculate the most rational transmission progression, transmission relevant parameters when according to different products or user's needs, is optimized design.Thereby gear reduction box can eccentric be exported, and also can export with one heart, and latter's structure can become entire machine design elongated shape, makes overall structure compacter, has promptly improved the runnability of motor, and is economical and practical again.
According to the utility model, described each gear reduction box comprises casing, case lid, train of reduction gears and output shaft, described train of reduction gears comprises first gear that is meshing with each other successively, second gear, the 3rd gear, the 4th gear and output gear, described first gear set is on the power transmission shaft of motor body, and described output gear is connected with output shaft; Adopt the external toothing mode between described first gear and second gear, the 4th gear and the output gear, engagement system in adopting between described second gear and the 3rd gear, described the 3rd gear and the 4th gear.This structure can guarantee that power transmission shaft and output shaft are concentric.Described second gear is a gear train on the benchmark circumference in the center of circle for evenly being arranged on the power transmission shaft.The gear quantity of this gear train is advisable with 2-4, decides preferred 3 on concrete designing requirement.Described second gear train is made of three gears.Described the 4th gear is one group, and evenly to be arranged on the power transmission shaft be gear train on the benchmark circumference in the center of circle.The gear quantity of this gear train is advisable with 2-4, decides preferred 3 on concrete designing requirement.After adopting gear train, for each gear in this gear train, its suffered driving force is less relatively, can make and operate steadily, and increase the service life.Gear for being meshed with this gear train can make its stress balance, and then makes the complete machine running more steady, improves the stability and the reliability of its operation.
According to the utility model, described motor body can be a direct current machine, also can be alternating current machine.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is an outline drawing of the present utility model.
Fig. 2 is the structural representation of the utility model gear reduction box.
Fig. 3 is that the A-A of Fig. 2 is to cutaway view.
Embodiment
With reference to Fig. 1, the motor of two ends output, motor body 1 adopts the standard permanent magnet DC motor, and power is 150W, and motor body 1 two ends are equipped with power transmission shaft and gear reduction box 2,3.With reference to Fig. 2,3, shown in the figure structure of right-hand member gear reduction box 2.Described gear reduction box 2 comprises casing 6, case lid 9, train of reduction gears and output shaft 4, described train of reduction gears comprises be meshing with each other successively first gear 7, second gear 8, the 3rd gear 10, the 4th gear 11 and output gear 13, described first gear 7 is sleeved on the power transmission shaft 12 of motor body, and described output gear 13 is connected with output shaft 12; Adopt the external toothing mode between described first gear 7 and second gear 8, the 4th gear 11 and the output gear 13, engagement system in adopting between described second gear 8 and the 3rd gear 10, described the 3rd gear 10 and the 4th gear 11.
Described second gear 8 is made of three gear 8-1,8-2,8-3, and evenly being arranged on power transmission shaft 12 is on the benchmark circumference 14 in the center of circle.Described the 4th gear 11 also is that three gears constitute, and evenly being arranged on power transmission shaft 12 is on the benchmark circumference in the center of circle.
The gear reduction box 3 of left end is identical with right-hand member gear reduction box 2 structures.
The transmission process of above-mentioned reduction gear box is as follows: after motor passes through, power transmission shaft 12 drives first gear 7 and rotates, and send this power to second gear train 8, the 3rd gear 10, the 4th gear train 11 and output gear 13 successively, at last from output shaft 4 output torques.When transmission behind first gear, 7 to second gear trains 8, center of rotation is transferred on the benchmark circumference 14 by drive of motor axle center 15; When transmission behind second gear train, 8 to the 3rd gears 10, center of rotation is transferred to the axle center of the 3rd gear 10 by benchmark circumference 14, this axle center overlaps with drive of motor axle center 15; When transmission behind the 3rd gear 10 to the 4th gear trains 11, center of rotation is transferred to the axle center of the 4th gear by the axle center of the 3rd gear 10, this axle center overlaps with benchmark circumference 14 in the present embodiment; When transmission from the 4th gear train 11 to output gear 13, center of rotation is transferred to the output gear axle center by benchmark circumference 14, this axle center overlaps with drive of motor axle center 15; Therefore the axle center of final output shaft 4 also overlaps with drive of motor axle center 15.
