Abstract
The invention discloses a rotating limiting structure of an automatic ice discharging device output gear. The rotating limiting structure comprises an output gear and a lower shell of an automatic ice discharging device electromechanical portion. A track the same as a rotating trajectory of the output gear is arranged at the position, corresponding to the output gear, inside the lower shell. The two ends of the track are provided with an opening limit and a closing limit. Concave and convex parts corresponding to the track are arranged on the face, opposite to the lower shell, of the output gear. The rotating limiting structure has the advantages that the track and the limits are additionally arranged on the rotating trajectory of the output gear; even if the output gear is not rotated in place at a certain time and rotated back, the output gear is rotated to the preset position and also prevented from rotating excessively due to the blocking of the limits, the output gear is still rotated from the preset rotating starting point next time, and the phenomenon that the output gear is derailed from a friction wheel is avoided; meanwhile, the vertical contact face is added on the track for the output gear, vertical waggling is avoided, and the structure is reliable and stable.
Description
Technical field
The present invention relates to a kind of gear mechanism, particularly a kind of can the limit structure of control gear rotation amplitude.
Background technique
Refrigerator goes out ice device automatically, is with DC motor Driver one group of gear drive, driving the coaxial ice mouth baffle plate connected to open and close, by controlling the forward and reverse rotation of direct current generator, realizing the opening and closing of ice mouth baffle plate by the output gear of final stage.
Output gear 1-1 as shown in Figure 1, it is a kind of special shape gear prevented in company with rotating, by the tooth 1-2 engagement driving on friction wheel and output gear 1-1, the rotation amplitude of output gear 1-1, directly determine the opening and closing amplitude of ice mouth baffle plate, rotation amplitude is not in place, opens and closes amplitude also not in place.By the flank of tooth arc length L of tooth 1-2 on design output gear 1-1, simultaneously by the duty cycle time T of setting direct current generator, both coordinate, and make output gear turn to end positions, ensure that ice mouth baffle plate is opened completely and closed completely.But this method requires high to design-calculated on the one hand, on the other hand, if output gear rotation amplitude in a duty cycle time T of direct current generator is not in place, then in next operating time T, will rotate excessively during output gear revolution, cause output gear and friction wheel to derail, cause ice mouth baffle plate cannot continue to open or close.
In accompanying drawing 1, output gear 1-1 is connected by axle 1-4 with the lower shell body 1-3 automatically going out ice device electro-mechanical parts, output gear 1-1 is by the fraction surface of contact with axle 1-4, and with the surface of contact of friction gear teeth transmission, stable effect is vertically being played to output gear 1-1, prevent from vertically teetertottering, but surface of contact is few, structural instability.
Summary of the invention
Goal of the invention: for the problems referred to above, the object of this invention is to provide a kind of special-shaped output gear rotation to automatically going out ice device and carry out spacing structure, even if certain rotation amplitude of output gear is not in place, rotates excessively when it also can not be caused to turn round and cause ice mouth baffle plate cannot continue to open or close.
Technological scheme: a kind of rotary position limiting structure automatically going out ice device output gear, comprise output gear, automatically go out the lower shell body of ice device electro-mechanical parts, in described lower shell body, corresponding to the position of described output gear, be provided with the track identical with described output gear rotary motion trace, described track two ends are provided with opens spacing and closed spacing, and described output gear is provided with corresponding concavo-convex with described track on the face relative with described lower shell body.
Described track comprises main orbit, auxiliary track, and the radial direction along described output gear rotary motion trace is arranged, and to the surface of contact that output gear adds on vertical, plays stabilization further to vertical direction.
Best, described auxiliary track is at least one, is arranged at described main orbit both sides.
Described track, built with lubricant oil, increases lubrication between track and output gear.
Beneficial effect: compared with prior art, advantage of the present invention is in the rotary motion trace of output gear, set up track and spacing, even if certain rotation amplitude of output gear is not in place, due to spacing stop after revolution, not only turn to predeterminated position but also prevent it from rotating excessively, remain when again turning to from the rotation starting point preset, there will not be output gear in friction wheel derailment occurring, simultaneously track surface of contact that output gear is added on vertical, prevent from vertically teetertottering, structure is reliable, stable.
Accompanying drawing explanation
Fig. 1 is that existing output gear is going out the structural representation in ice device electro-mechanical parts housing automatically;
Fig. 2 is structural representation of the present invention, and output gear goes to closed spacing;
Fig. 3 be in Fig. 2 output gear go to open spacing;
What in Fig. 2, Fig. 3, dotted line represented is output gear.
Embodiment
Below in conjunction with the drawings and specific embodiments, illustrate the present invention further, these embodiments should be understood only be not used in for illustration of the present invention and limit the scope of the invention, after having read the present invention, the amendment of those skilled in the art to the various equivalent form of value of the present invention has all fallen within the application's claims limited range.
As shown in Figure 2, a kind of rotary position limiting structure automatically going out ice device output gear, comprises output gear 1, automatically goes out the lower shell body 2 of ice device electro-mechanical parts.
In lower shell body 2, corresponding to the position of output gear 1, be provided with the track 3 identical with output gear 1 rotary motion trace, comprise main orbit 31, auxiliary track 32, radial direction along output gear 1 rotary motion trace is arranged, and auxiliary track 32 can be more than one, is arranged at main orbit 31 both sides.
Track 3 two ends are provided with opens spacing 4 and closed spacing 5, and output gear 1 is provided with corresponding concavo-convex with track 3 on the face relative with lower shell body 2, concavo-convexly fastens with track 3, but is not clamping, should be smooth and easy, also lubricant oil is housed in track 3.
With the position identified in accompanying drawing 2,3, rotation process of the present invention is described.
As shown in Figure 2, output gear is in the closed spacing of left end, and now ice mouth baffle plate is closed completely, then direct current generator carries out the work of a duty cycle time T, the unlatching that output gear turns to the right-hand member shown in Fig. 3 is spacing, and now ice mouth baffle plate is opened completely, and so forth.
If go to closed spacing process at output gear from unlatching is spacing, to skid between output gear and friction wheel 6 or because of other reason, output gear is caused not reach closed spacing, ice mouth baffle plate is not closed completely, so in the output gear process that from then on position turns to unlatching spacing again, owing to opening spacing stop, output gear can not ovdersteering and derailing with friction wheel, ice mouth baffle plate is still in the position of opening completely, after this, output gear still rotates from unlatching is spacing to closed spacing direction, and ice mouth baffle plate is normally closed.Vice versa.
The surface of contact that track adds on vertical output gear, plays stabilization further to vertical direction, prevents output gear teetertottering in vertical direction.
