Traditional actuating unit generally adopts the split-type design method, that is: 1. power section and variable part are separately independently on function; 2. correspondingly, structurally, also with the two design mix from two devices.For example,, as the variable part, and between the two, connect as power section with motor with gear reduction unit by coupling.
Existing transmission gear shift part has a variety of forms, as divided gear reducer, worm reducer, plane table thermoconductivity meter, cycloidal-pin wheel retarder and five kinds of forms of harmonic wave size retarder by transmission and structural feature.Wherein plane table thermoconductivity meter is to be formed by the spur gear engagement, in " design of involute gear Gear Planet Transmission and manufacturing " book of publishing according to China Machine Press 2,002 4~5 pages described, planet size retarder is compared with common size retarder has that volume is little, in light weight, compact structure, transmitted power is big, bearing capacity is high, velocity ratio is big, transmission efficiency height, motion steadily, the stronger characteristics of ability of shock resistance and vibration, thereby obtained extensive use.But traditional planetary reducer medium power part and variable part remain the device that separates between the two, and this has not only increased the volume and the weight of whole transmission device, and has reduced whole transmission efficiency.
The overall volume and the weight that reduce device have become pressing for of raising efficiency of energy utilization, especially in some fields strict to volume and weight, and taked relative measures, as having set forth the development trend of tank power in " system of promoting comprehensively-tank power development trend " literary composition in " vehicular engine " fourth phase calendar year 2001: development is promoted comprehensively system to dwindle tank overall sizes, to alleviate the tank quality in the tank design, improve the power output performance, and proposed each parts and make the as a whole necessity of considering.
According to the information of announcing on the http://www.hsimotors.com/rotory-stepping-motors/planetary-gear-train.htm website, Haydon Switch ﹠amp; Instrument company has developed a kind of transmission device product that retarder and motor are combined, and it is compared with traditional retarder, the compactness that structure becomes, and efficient further is improved; But essentially, its motor and retarder remain independently two parts, and it is that retarder is reduced to be put in the motor at all.
Summary of the invention
The technical problem to be solved in the present invention is, overcomes existing transmission device medium power part and the variable part is separated, structure problems such as compactness, transmission efficiency be low inadequately.At existing design with based on the theory of global design, provide a kind of motor gear integrated dynamic transmission device.It has higher transmission efficiency than existing plane table thermoconductivity meter or common gear reducer, and structure space is compact more, and it is that motor is fused in the size of planetary reducer at all, makes that the two one-tenth is as a whole.
Technological scheme of the present invention: this transmission device is made up of power section and variable part.Described variable part comprises: sun gear, planetary pinion, ring gear, planet carrier and output shaft.Sun gear and planet wheel engagement, on shell, planet carrier is connected by bolt with output shaft ring gear by screw.Described power section comprises: power supply lead wire, pole shoe, jointer electrode, jointer are drawn axle, coil and rotor.Coil stationary is in ring gear, and the front end of rotor is connected with output shaft by screw, and draw on the axle at jointer by bearings the rear end, and the center line that jointer is drawn axle, rotor, planet carrier and output shaft on an axis; Described jointer draw a front end by bolt on sun gear, the rear end by bearings on shell, jointer is hollow in the middle of drawing axle, the hollow parts that the power line of coil is drawn axle by jointer is connected with the jointer electrode that jointer is drawn shaft tail end, and the jointer electrode is installed in jointer and draws that axle is gone up and insulate with its maintenance; Described jointer electrode keeps in touch constantly with pole shoe in the process of rotation, thereby external power supply is introduced the jointer electrode, and then introduces coil; Described pole shoe be installed in that connection jaws covers and with its maintenance insulation; The wiring flap is by being bolted on the shell; Described power supply lead wire is connected with pole shoe, and power lead-ining line circle the most at last.
The present invention has such beneficial effect, be to have saved elements such as shaft joint, bearing between power section and the variable part, it is good to connect coupling, has made full use of the space of variable part, the overall weight of transmission system is greatly reduced, and improved the whole efficiency of system effectively; Variable part provided by the present invention utilizes existing technology to realize, the manufacturing of entire system, assembling realizability have reduced the volume and weight of transmission system by force, significantly, and by reduce element such as shaft joint, bearing waits and improves system's transmission efficiency, improve precision, increase the transmission system reliability.
