Description
Technical field:
The utility model relates to the transmission device technical field, refer in particular to a kind of control and carry out action accurately, sensitive, reliably and not can produce the electromagnetic clutch type harmonic speed reducer that is used for precision drive of electrical spark.
Background technique:
General drive mechanism mostly utilizes mechanical structure to realize, perhaps the mechanism of pure electromagnetic type; These existing drive mechanisms exist easily carries out defectives such as accuracy of action is poor, sensitivity is not high, reliability is bad; Transmission for precision just seems not enough, especially aspect military project or precision type instrument.
The model utility content:
The technical problem that the utility model solves be to provide a kind of control and carry out action accurately, sensitive, reliably and not can produce the electromagnetic clutch type harmonic speed reducer that is used for precision drive of electrical spark.
Technical problem of the present utility model is achieved by the following technical solution: comprise housing, motor connecting plate, input shaft, adapter sleeve, clutch plate, armature, braking vane, yoke and shell head; Motor connecting plate and shell head are connected with housing respectively, are furnished with adapter sleeve, clutch plate, armature, braking vane and yoke on the input shaft in regular turn; Adapter sleeve can be fixed on the input shaft, and yoke is fixed on the housing; Between armature and braking vane, be provided with the spring of nature; Also comprise interior cover, a left side just wheel seat, a left side just wheel, joint sleeve, right just wheel seat, the right side just take turns, flexbile gear; Interior cover, a left side just wheel seat, flexbile gear and right firm wheel are arranged in regular turn; Interior being placed on the input shaft, the one end places between clutch plate and armature, and the other end is connected by the firm wheel seat of a joint sleeve and a left side; The left and right firm wheel that is fixed on the left and right firm wheel seat can mesh with flexbile gear respectively; Right wheel seat just links to each other with output shaft.
Between flexbile gear and left and right firm wheel, be provided with the thrust washer of thrust.
Be provided with bearing between left and right firm wheel and shell head.
Clutch plate and braking vane difference screw are in adapter sleeve and brake panel seat; And it is all along the finedraw that is provided with contraction deformation at clutch plate and braking vane.
Adapter sleeve be fixed on the input shaft the position along input shaft axially on an adjustable stroke is arranged.
The utility model utilizes the clutch of electromagnetic type, can realize the output of two kinds of velocity ratios, and switches easily, and control is reliable, and two transmission speed ratio intervals are very big; When armature was switched on, transmission speed ratio was 1: 1; During the armature outage, transmission speed ratio can be very big, but concrete parameter artificer selects harmonic device as required; As 1: 80.Because friction plate is the outside that is convexly set in clutch plate and braking vane fully, thus armature can be directly and friction plate do contact friction completely, consequently can not produce noise and spark.Clutch plate of the present utility model and braking vane are that direct spiral shell is located on adapter sleeve and the brake panel seat, all at it along having cut finedraw, when being screwed into, Locking screw can utilize the contraction of this finedraw, and its distortion is packed on adapter sleeve and the brake panel seat, so after using a period of time, when this friction plate is frayed, need only loosen Locking screw, gap between clutch plate and braking vane and armature is turned down, just can make its action reach to be quick on the draw, optimum efficiency accurately and reliably.The adjustable in the axial direction solidating fixed position of adapter sleeve on the input shaft, thus adjust the gap of clutch, adjust the gap after the tightening Cock screw get final product; Thereby its clutch action is reached cause be quick on the draw, optimum efficiency accurately and reliably.And,, thereby can make the startup braking torque force bigger so the amount of leakage field is minimum or do not leak because armature is a plane and need not establish the isolation channel that runs through.Because the utility model effectively and compact magnetic clutch and harmonic device are coupled together, and the housing of electromagnetic clutch retarder is divided into two, and is convenient to install, debugging and maintenance, and is in light weight, volume is little.In input one regularly, the conversion of output velocity ratio only need realize by the switching electricity of control magnetic clutch, thus control and the adjustment easily of output velocity ratio, and the scope of adjusting is bigger.Because total number of teeth in engagement is more during Harmonic Gears, promptly the number of teeth of bearing load is more simultaneously, and when other conditions were identical, its bearing capacity can improve greatly than other forms of transmission.Because the relative sliding velocity of engaging tooth is extremely low.Therefore loss is little, and can work under the situation of processing roughness and poor lubrication.Because of flexbile gear during with wheel engagement just, tooth and between cog even contact, tooth engaging-in and nibbling out carries out gradually with the distortion of flexbile gear.Thereby the wearing and tearing of tooth are little and even, and motion does not steadily have impact.
