Abstract
The utility model discloses a miniature DC (Direct Current) hoisting machine which comprises a housing, wherein a motor, a speed reducer and a winding drum are arranged in the housing; the motor is a DC motor; an output gear is arranged at one end part of the output shaft of the motor; the speed reducer comprises a planet carrier, a planet gear, a static internal gear, a movable internal gear and a planet gear shaft; the planet gear shaft is movably sleeved in the planet gear and fixedly connected with the planet carrier; the static internal gear and the movable internal gear are arranged on the outer side of the planet gear and are together in gear mesh transmission with the planet gear; the planet gear is in mesh transmission with the output gear; and the movable internal gear is in transmission connection with a winding drum shaft. Through the adoption of the DC motor, the application range of the hoisting machine is enlarged, for example, the hoisting machine can be used on a truck which only has a DC supply. Therefore, the hoisting machine has a wide market prospect in nowadays society with increasing labor cost.
Description
Technical field
The utility model relates to a kind of lifting weight-lifting equipment, particularly a kind of minisize dc machine that hoists.
Background technology
The machine of hoisting is a kind of general lifting weight-lifting equipment that uses, and occurs on market and the data and the machine that hoists report mainly is the usefulness alternating current as propulsion source, is divided into industrial and two kinds of family expenses; Industrial be the three-phase machine that hoists, mostly its structural shape is to adopt phase asynchronous taper braking motor, reel, the coaxial in turn connection of retarder; Family expenses for the single-phase machine that hoists, mostly its structural shape is to adopt single-phase asynchronous side magnetic braking motor, retarder, the coaxial in turn connection of reel.Because the existing machine of hoisting can only be satisfied with the occasion that source of AC is arranged, and just powerless for the occasion of having only direct supply.
Summary of the invention
The utility model has overcome the deficiency that prior art exists, and provides a kind of simple in structure, safe in utilization, the minisize dc that is suitable for the direct supply occasion machine that hoists.
For achieving the above object, the utility model adopts following technical scheme: a kind of minisize dc machine that hoists, include housing, be provided with motor in the housing, retarder and reel, described motor is a DC machine, when remaining static, its both positive and negative polarity input end direct connection, form a C/LOOP, the end of the output shaft of motor is provided with an output gear, described retarder includes pinion carrier, satellite gear, quiet inner gear, moving inner gear and planet wheel spindle, described planet wheel spindle is actively socketed in the satellite gear, and described pinion carrier is captiveed joint with planet wheel spindle, described quiet inner gear and moving inner gear are arranged on the outside of satellite gear, and together with satellite gear gear engaged transmission, described satellite gear and output gear engaged transmission, described moving inner gear and drum shaft are in transmission connection.
The utility model can be directly be input to the corresponding both positive and negative polarity of motor with the both positive and negative polarity of direct supply, and motor produces power, power is passed to reel and weight is promoted through retarder.
The beneficial effects of the utility model are, owing to selected DC machine for use, have enlarged the use occasion of the machine that hoists, and such as using having only on the goods carrying vehicle of direct supply, the current society in that labor cost increases day by day has vast market prospect.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described:
Accompanying drawing is the structural representation of the utility model embodiment;
1. housings among the figure, 2. motor, 21. output shafts, 211. output gears, 3. retarder, 31. pinion carriers, 32. satellite gears, 33. quiet inner geares, 34. moving inner geares, 4. reel, 41. drum shaft.
The specific embodiment
With reference to accompanying drawing, a kind of minisize dc machine that hoists, include housing 1, be provided with motor 2 in the housing 1, retarder 3 and reel 4, described motor 2 is a DC machine, when remaining static, its both positive and negative polarity input end direct connection, form a C/LOOP, the end of the output shaft 21 of motor 2 is provided with an output gear 211, described retarder 3 includes pinion carrier 31, satellite gear 32, quiet inner gear 33, moving inner gear 34 and planet wheel spindle 35, described planet wheel spindle 35 is actively socketed in the satellite gear 32, and described pinion carrier 31 is captiveed joint with planet wheel spindle 35, described quiet inner gear 33 and moving inner gear 34 are arranged on the outside of satellite gear 32, and together with satellite gear 32 meshed transmission gear, described satellite gear 32 and output gear 211 meshed transmission gear, described moving inner gear 34 is in transmission connection with drum shaft 41.
Concrete principle of work of the present utility model is: the both positive and negative polarity of direct supply is input to motor 2 corresponding both positive and negative polarities, this moment motor 2 output shaft 21 high speed rotating, described output gear 211 rotates synchronously, drives satellite gear 32 and rotates, under the effect of pinion carrier 31, quiet inner gear 33 and planet wheel spindle 35, moving inner gear 34 slowly runs, promptly rotating speed is reduced, and give drum shaft 41, drum shaft 41 is slowly run transmission of power by retarder 3, drive reel 4 and rotate, thereby weight is promoted; If the transposing of the both positive and negative polarity of direct supply is input to motor 2 corresponding both positive and negative polarities, motor 2 reverse high speed rotating at this moment, reel 4 is backward rotation also, and weight is transferred; When the cut-out direct supply, when motor 2 is remained static, with the both positive and negative polarity input end connection of motor 2, form a C/LOOP, the weight that is suspended on this moment on the reel 4 descends, and with reverse motor 2 output shafts 21 that pass to of torque, makes its rotation, this C/LOOP is done cutting magnetic line movement in magnetic field, produced opposing torque, hindered being rotated further of output shaft 21, made weight stop to descend, play the effect of braking, improved the safety of operation coefficient of machine greatly.
