Abstract
The utility model discloses a take-over type harmonic gear reducer. The take-over type harmonic gear reducer comprises a shell body (1). A steel wheel (2), a harmonic generator (3), and a flexible wheel (4) are fixedly connected with the inside of the shell body, wherein the steel wheel (2) is provided with an inner gear ring (21). One end of the flexible wheel (4) is provided with an outer gear ring (41), and the other end of the flexible wheel (4) is provided with an inner gear ring (42). The harmonic generator (3) is installed at one end of the flexible wheel (4), wherein the end of the flexible wheel (4) is provided with the outer gear ring (41). The flexible wheel (4) is meshed with the inner gear ring (21) of the steel wheel (2) through the outer gear ring (41). The flexible wheel (4) is meshed with an outer gear ring (51) of an output take-over sleeve (5) through the inner gear ring (42). The output take-over sleeve (5) penetrates an end cover (11) and extends out of the shell body (1). Firstly, the take-over type harmonic gear reducer effectively resolves the problems that a combination of an output shaft and an input shaft is adopted in an existing harmonic gear reduction motor to form a torque output mechanism, the structure is complex, the size of the entire machine is difficult to down-regulate, and the applicable installation conditions are restricted to some extent. Secondly, the problems that an output shaft is used in the existing harmonic gear reduction motor as power output, a coupler is needed for cooperation, and enterprise usage cost is increased are resolved. Lastly, the problems that an existing harmonic reducer generally integrates the motor and can not be independently matched with other motors, and therefore application environment is restricted are resolved.
Description
Technical field
The utility model relates to retarder technical equipment field, is specifically related to take over the formula harmonic gear reducer.
Background technique
Harmonic gear reducer is a kind of new type speed reducer that utilizes the planetary pinion transmission principle to grow up, Harmonic Gears (abbreviation harmonic driving), and it is to rely on flexible part to produce a kind of planetary pinion transmission that the elastic mechanical ripple comes transferring power and motion.Harmonic gear reducer is because of it possesses the bearing capacity height, velocity ratio is big, transmission efficiency is high, the life-span is long, stable drive, nothing are impacted, noise free, and the kinematic accuracy advantages of higher is widely used in fields such as electronics, chemical industry, space flight and aviation, robot.At present; Existing harmonic gear reducer adopts the combination of output shaft and output wheel to constitute the moment of torsion output mechanism usually; Because the restriction of the internal structure of existing retarder can't be made the output that receives the cover form, make just comparatively compact originally inner space seem complicated, the place that some are had relatively high expectations to the equipment installation dimension; Perhaps because of its size can't possess installation conditions, limited its using scope to a certain extent; Secondly,, generally need be connected with transmission device, also improve the user cost of enterprise to a certain extent through coupling because existing harmonic gear reducer adopts output shaft to export as power.
Summary of the invention
The utility model purpose provides catcher formula harmonic gear reducer, and the utility model at first effectively solves existing harmonic gear reducer and adopts the combination of output shaft and output wheel to constitute the moment of torsion output mechanism, and mechanism is complicated; The complete machine size is difficult to downward modulation; The problem that causes its suitable installation environment to be restricted to a certain extent, next has solved existing harmonic gear reducer and has adopted output shaft to export as power, needs to cooperate coupling to use; Improved the problem of enterprise's user cost; Having solved the general and motor of existing harmonic speed reducer at last is one, can not match with other motors separately, causes the restricted problem of suitable environment.
The utility model is realized through following technological scheme:
Catcher formula harmonic gear reducer comprises housing, and the housing internal fixation is connected with steel wheel, harmonic generator, the flexbile gear that is provided with ring gear; One end of said flexbile gear is provided with external toothing; The other end end is provided with ring gear, and harmonic generator is arranged at the end that flexbile gear is provided with external toothing, and flexbile gear is meshed through the set ring gear of external toothing and steel wheel; Flexbile gear is meshed with the set external toothing of output catcher cover through ring gear, and output catcher cover passes end cap and stretches out housing.
The further technological scheme of the utility model is:
Said steel wheel is fixedly connected with housing through fastening piece.
The utility model technological scheme further is:
Said output catcher cover is provided with the keyway that is complementary with transmission device.
The utility model compared with prior art has following obvious advantage:
The utility model is improved catcher formula harmonic gear reducer on the basis of harmonic gear reducer; The utility model makes full use of the internal structure of harmonic gear reducer; Flexbile gear is combined with output catcher cover; The existing output shaft moment of torsion output mechanism of forming that combines with output wheel is replaced with output catcher cover, form a new type speed reducer that integrates speed reducer and gear coupling, not only reduced the manufacture cost of existing harmonic gear reducing motor; Simplified internal structure; It is more reasonable that the complete machine size also becomes, and improved the applicability of Environmental Conditions, and this retarder can effectively be realized gearing down with any drive motor in different operating environments; And, also, equipment practiced thrift the cost of buying coupling for using producer because the utility model adopts the output of catcher cover form.
