Abstract
A conductive slip ring of a two-pole inner feedback speed adjusting motor comprises a slip ring inner body 2. At least a slip ring 3 is embedded in the outer part of the slip ring inner body 2; at least a heat dissipation groove 4 is formed at the top part or on two sides of the slip ring 3; and a ventilation hole 5 is formed on the slip ring 3 in the axial direction. The heat dissipation groove 4 and the ventilation hole 5 are formed on the slip ring 3, so that the radiating effect is reinforced, the radiating problem is solved, the effects of removing aircushion and exhausting powder are eliminated, and the current and the signal of the two-pole inner feedback speed adjusting motor can be accurately transmitted.
Description
Technical field
The utility model relates to the conducting slip ring field, particularly relates to a kind ofly realizing that two relatively rotate the signal of mechanism and the accurate power transmitting device of current delivery, be particularly useful for two extremely in the feedback bunchers.
Background technology
As everyone knows, conducting slip ring is used for that relative mechanical rotation place's transmission current and signal are being arranged, and it just is being widely used in the technical field of automation, has obtained in each field widely applying.But, existing conducting slip ring two extremely in the feedback buncher application in be restricted.
Two extremely in the great advantage of feedback bunchers be exactly can be regulating high-power, high-tension motor speed than the control appliance of low capacity and voltage, thereby reduce the investment of whole governing system.Yet the rotor current of two extremely interior feedback bunchers is big, and the slip ring number that needs is many, and as calculated, the number of slip ring must be more than 400, and as if being that example is calculated with 400, the linear velocity of conducting slip ring is 3000 * 3.14 * 0.4/60=62.8m/s.General conducting slip ring is under so big electric current and so high linear velocity situation, and heating is relatively more severe, and it is out of condition to dispel the heat, and can not guarantee the accurate transmission of current of electric and signal.
The content of utility model
The applicant improves research at the problems referred to above, and the conducting slip ring of a kind of two extremely interior feedback bunchers is provided, and the conducting slip ring caloric value that solves two extremely interior feedback bunchers is big, the bad problem of dispelling the heat.
The technical solution of the utility model is as follows:
Two extremely in the conducting slip rings of feedback bunchers, it comprises slip ring endosome 2, slip ring endosome 2 outsides are inlayed and are provided with at least one slip ring 3, the top of slip ring 3 and both sides offer at least one radiating groove 4, slip ring 3 axially offer ventilation hole 5.
Useful technique effect of the present utility model is:
The utility model is opened measures such as axial ventilation hole by add radiating groove on slip ring, has strengthened radiating effect, thereby has solved heat dissipation problem.
And, the slip ring top can produce air cushion because contacting with brush, slip ring top radiating groove can be the air scavenge that forms on the slip ring, reduce the gas pressure on the slip ring, eliminate ground effect phenomenon, guaranteed the slip-ring current distributing homogeneity and guaranteed that the slip ring temperature rise is unlikely to too high.In conducting slip ring when wearing and tearing,, itself also can produce dust impurity such as carbon dust, so radiating groove also can play the effect of getting rid of dust, improves conducting slip ring ambient air quality.
Description of drawings
Fig. 1 is a structure chart of the present utility model.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described further.
As shown in Figure 1, the conducting slip ring of two extremely interior feedback bunchers, it is in motor shaft 1 one ends and its formation one, it comprises slip ring endosome 2, slip ring endosome 2 outsides are inlayed and are provided with at least one slip ring 3, the top of slip ring 3 and both sides offer at least one radiating groove 4, slip ring 3 axially offer ventilation hole 5.
By on conducting ring, adding radiating groove 4, open axial ventilation hole 5 measures such as grade, strengthened heat radiation, the accounting temperature of slip ring is controlled in 75 ℃, the operating temperature of actual measurement is 63 ℃.
The slip ring top contacts with brush and can produce air cushion, and slip ring top radiating groove can reduce the gas pressure on the slip ring to the air scavenge that forms on the slip ring, eliminates ground effect phenomenon, has guaranteed the slip-ring current distributing homogeneity and has guaranteed that the slip ring temperature rise is unlikely to too high.
In conducting slip ring when wearing and tearing,, itself also can produce dust impurity such as carbon dust, so radiating groove can play the effect of getting rid of dust, improves conducting slip ring ambient air quality.
