Abstract
The invention discloses a kind of rotary position limiting structure for going out ice device output gear automatically, including output gear, automatically go out ice device electro-mechanical parts lower house, in the lower house, corresponding to the position of the output gear, it is provided with and the output gear rotary motion trace identical track, the track, which is provided at both ends with, opens spacing spacing with closure, and the output gear is provided with the bumps corresponding with the track on the face relative with the lower house.It is an advantage of the invention that setting up track in the rotary motion trace of output gear and spacing, even if certain rotation amplitude of output gear is not in place, stopped after revolution due to spacing, not only predeterminated position had been turned to but also had prevented it from rotating excessive, it is not in output gear in friction pulley derailment occurring since default rotation starting point to be still when returning again to, while track adds the contact surface on vertical to output gear, prevent from vertically teetertottering, structure is reliably, stably.
Description
Technical field
It is particularly a kind of to control the position limiting structure of pinion rotation amplitude the present invention relates to a kind of gear mechanism.
Background technology
Refrigerator goes out ice device automatically, is, with one group of gear drive of DC motor Driver, to be driven by the output gear of final stage
Coaxially connected ice mouth baffle plate is opened and closed, and by controlling the forward and reverse rotation of direct current generator, realizes opening for ice mouth baffle plate
Open and close.
Output gear 1-1 as shown in Figure 1, is a kind of special shape gear for preventing companion from rotating, passes through friction pulley and output
Tooth 1-2 engaged transmissions on gear 1-1, output gear 1-1 rotation amplitude directly determines unlatching and the pass of ice mouth baffle plate
Amplitude is closed, rotation amplitude is not in place, open and close amplitude also less than position.By the flank of tooth for designing tooth 1-2 on output gear 1-1
Arc length L, while the duty cycle time T by setting direct current generator, both coordinate, and output gear is turned to end positions,
Ensure that ice mouth baffle plate is fully opened and a fully closed.But on the one hand this method requires high to design-calculated, the opposing party
Face, if output gear rotation amplitude in a duty cycle time T of direct current generator is not in place, in next work
Between in T, output gear will be rotated excessively when turning round, and caused output gear to be derailed with friction pulley, caused ice mouth baffle plate can not
Continue on or close.
In accompanying drawing 1, output gear 1-1 is connected with going out the lower house 1-3 of ice device electro-mechanical parts automatically by axle 1-4, output
Gear 1-1 is by the fraction contact surface with axle 1-4, and the contact surface with friction gear teeth transmission, to output gear 1-1 perpendicular
To stable effect is played, prevent from vertically teetertottering, but contact surface is few, structural instability.
The content of the invention
Goal of the invention：In view of the above-mentioned problems, it is an object of the invention to provide a kind of special-shaped output gear to going out ice device automatically
Wheel, which is rotated, carries out spacing structure, even if certain rotation amplitude of output gear is not in place, is rotated when also not resulting in its revolution
Spend and cause ice mouth baffle plate can not continue on or close.
Technical scheme：It is a kind of automatically go out ice device output gear rotary position limiting structure, including output gear, automatically go out ice device
The lower house of electro-mechanical parts, in the lower house, corresponding to the position of the output gear, is provided with and the output gear
Rotary motion trace identical track, the track be provided at both ends with unlatching it is spacing and close it is spacing, the output gear with it is described
Lower house is provided with the bumps corresponding with the track on relative face.
The track includes main orbit, auxiliary track, along being radially arranged for the output gear rotary motion trace, to output gear
The contact surface on vertical is added, stabilization is further functioned as to vertical direction.
Optimal, the auxiliary track is at least one, is arranged at the main orbit both sides.
The track is lubricated increasing between track and output gear built with lubricating oil.
Beneficial effect：Compared with prior art, it is an advantage of the invention that setting up track in the rotary motion trace of output gear
With it is spacing, even if certain rotation amplitude of output gear is not in place, after revolution due to it is spacing stop, not only turned to predeterminated position again prevent
Only it rotates excessive, and it is not in that output gear is de- in friction pulley since default rotation starting point to be still when returning again to
Rail phenomenon, while track adds output gear the contact surface on vertical, prevents from vertically teetertottering, and structure is reliable, surely
It is fixed.
Brief description of the drawings
Fig. 1 is structural representation of the existing output gear in ice device electro-mechanical parts housing is gone out automatically；
Fig. 2 is schematic structural view of the invention, and it is spacing that output gear goes to closure；
It is spacing that Fig. 3 goes to unlatching for output gear in Fig. 2；
In Fig. 2, Fig. 3 dotted line represent for output gear.
Embodiment
Below in conjunction with the accompanying drawings and specific embodiment, the present invention is furture elucidated, it should be understood that these embodiments are merely to illustrate
The present invention rather than limitation the scope of the present invention, after the present invention has been read, those skilled in the art are each to the present invention's
The modification for planting the equivalent form of value falls within the application appended claims limited range.
As shown in Figure 2, it is a kind of to go out the rotary position limiting structure of ice device output gear automatically, including output gear 1, go out automatically
The lower house 2 of ice device electro-mechanical parts.
In lower house 2, corresponding to the position of output gear 1, it is provided with and the rotary motion trace identical track of output gear 1
3, including main orbit 31, auxiliary track 32, along being radially arranged for the rotary motion trace of output gear 1, auxiliary track 32 can with more than one, if
It is placed in the both sides of main orbit 31.
Track 3 is provided at both ends with unlatching spacing 4 and closure spacing 5, and output gear 1 is set on the face relative with lower house 2
The bumps corresponding with track 3 are equipped with, bumps are fastened with track 3, but are not clampings, should be smooth, and profit is also equipped with track 3
Lubricating oil.
With the position identified in accompanying drawing 2,3, illustrate rotation process of the present invention.
As shown in Figure 2, closure of the output gear in left end is spacing, and now ice mouth baffle plate is completely closed, Ran Houzhi
The work that motor carries out a duty cycle time T is flowed, the unlatching that output gear turns to the right-hand member shown in Fig. 3 is spacing, now
Ice mouth baffle plate is fully opened, and so on.
If output gear from open it is spacing go to closure it is spacing during, beaten between output gear and friction pulley 6
Slide or because of other reasons, cause output gear not reach that closure is spacing, ice mouth baffle plate is not completely turned off, then output
Gear from this position turn again to open it is spacing during, due to opening spacing stop, output gear will not ovdersteering and
Derailed with friction pulley, ice mouth baffle plate is in the position fully opened, hereafter, output gear is still spacing to closing from opening
Close spacing direction to rotate, ice mouth baffle plate normal switching-off.Vice versa.
Track adds the contact surface on vertical to output gear, further functions as stabilization to vertical direction, prevents
Only output gear teetertottering in vertical direction.
