Abstract
The invention relates to a low noise decelerator for controlling the winding speed of a rotating roll, which comprises a separate decelerator combined with one side of a casing and being rotated together with an internal rotary roller. The decelerator comprises a housing combined with the casing, a drive gear arranged inside the housing, an intermittent gear used for transmitting or disconnecting the rotation force of the rotary roller, and a connecting mechanism connected with the above gears and combined with the rotary roller. Due to the adoption of the low noise decelerator, when the rotary roller is rotated positively under the action exerted in the unwinding direction of an insect proof net, the rotation force is not transmitted to the brake rubber. Therefore, the unfolding operation is smooth and easy. When the rotary roller is rotated reversely under the action exerted in the winding direction of the insect proof net, the rotation force is transmitted to the brake rubber. The rotation speed of the rotary roller is decreased due to the interference friction force between the brake rubber and a brake ring, so that the rapid winding of the rotary roller and resulting noises and damage are avoided. The centrifugal force exerted on the brake rubber is proportionally reduced along with the winding speed, so that the insect proof net is wound at a certain speed all the time.

Therefore, the present invention does the used time realizing auto reeling as above, by reduce this rotating roller 2 towards reciprocal rotational speed, be included in thereby overcome the problems that the problem such as noise or collision that produces under fast state exists in interior speed reducer in the past.
Therefore, speed reducer according to the present invention possesses the shell 10 that carries out combination by methods such as bolt or pressure insertions at a side end of housing 1, form jut 12 is installed from a side of this shell 10, and on above-mentioned installation jut 12 in conjunction with independent lid 60, thereby the interior formation space portion of jut 12 is being installed, now in this space portion intermeshing configuration flashboard 20 be connected gear 30 and interrupter gear 40 and actuation gear 50, the insertion axle 51 of above-mentioned actuation gear 50 connects lid 60 and gives prominence to, thereby for the independent bindiny mechanism 70 and these insertion axle 51 combinations of above-mentioned rotating roller 2 combinations.
More particularly, on a side of above-mentioned shell 10, be formed with the brake hoop 11 of circular groove shapes to the inner side that jut 12 is installed.In addition, on a side of above-mentioned flashboard 20 by pin in conjunction be inserted with eccentric state the brake rubber block 22,22 of the inner side that is arranged on above-mentioned brake hoop 11 ', on the another side of brake hoop 11, outstanding being formed with transmitted gear 21.Now, above-mentioned brake rubber block 22,22 ' combining structure be mutually depart from a side-prominent formation of flashboard 20 two in conjunction with pin 24, and brake rubber block 22,22 ' on run through respectively the joining hole 25 that is formed with a lateral deviation heart state, by brake rubber block 22,22 ' joining hole 25 insert above-mentioned combination pin 24 and assemble, thereby brake rubber block 22,22 ' can be to be rotated as axle point in conjunction with pin 24, thus from act on brake rubber block 22,22 ' rotating force receive centrifugal force, realize to the active state of inner rotary.
In addition, at a side outstanding another transmission gear 31 that is formed with again of above-mentioned connection gear 30, transmit gear 41 outstanding being equally formed with of a side of interrupter gear 40, insert axle 51 side-prominent being formed with of actuation gear 50.
Thereby, after flashboard 20 is installed in the inner side of the brake hoop 11 of above-mentioned shell 10, gear 30 is connected with a joggle on the transmission gear 21 of flashboard 20, on the transmission gear 31 that connects gear 30, engage interrupter gear 40, mesh driving gear 50 on the transmission gear 41 of interrupter gear 40, thus the transmit mode of the rotating force of each gear formed.
Now, above-mentioned interrupter gear 40 has the outstanding running shaft 42 forming in central authorities, this running shaft 42 be formed on shell 10 and slit groove 13 combinations on corresponding lid 60 with this shell 10, can between shell 10 and lid 60, move about thereby running shaft 42 is assembled into above-mentioned interrupter gear 40 along rectangular slit groove 13.
Therefore, the rotating force that acts on above-mentioned rotating roller 2 is delivered to actuation gear 50 by bindiny mechanism 70, this actuation gear 50 is delivered to interrupter gear 40 and is connected gear 30, and make and flashboard 20 High Rotation Speeds that are connected 30 one-tenth engagements of gear, along with the rotation of above-mentioned flashboard 20, brake rubber block 22 in eccentric pin bonding state, 22 ' by rotary centrifugal force and the flared while inner face ground connection with brake hoop 11, thereby according to ground connection frictional force each other, rotating force to flashboard 20 is inhibited, its result can realize the decelerating effect to rotating roller 2.
At this, above-mentioned brake rubber block 22, 22 ' in the rotational speed of flashboard 20 faster in situation, it is large that centrifugal force becomes, and the ground connection frictional force between brake hoop 11 increases, thereby deceleration effect rises, and in the case of the rotational speed of flashboard 20 is lower, centrifugal force diminishes, and the ground connection frictional force between brake hoop 11 reduces, and earthing effect reduces, therefore be that the situation of high speed or the situation of low speed are irrelevant with the winding speed that acts on rotating roller 2, the retarding force of the level corresponding with this speed is provided, thereby realizing makes this fly net 3 from start to finish can be with the curling effect of uniform speed.
For example, will it is curling under the state launching completely at fly net 3 time, the compressive force of spring assembly is maximum in the early stage, therefore, the rotating roller 2 that is now combined with fly net 3 is carried out opposite spin with very fast speed, and such High Rotation Speed power result can increase the rotational speed of flashboard 20, strengthen brake rubber block 22 simultaneously, 22 ' centrifugal force and increase with brake hoop 11 between ground connection frictional force, thereby increase decelerating effect, till fly net 3 is crimped onto the position adjacent with housing 1 time, the compressive force of spring assembly weakens greatly, therefore the reciprocal winding speed of rotating roller 2 can reduce naturally, and the brake rubber block 22 of the flashboard 20 that rotational speed is lowered, 22 ' centrifugal force also die down thereupon, therefore the interference frictional force and between brake hoop 11 declines, form the faint decelerating effect to opposite spin power.
Therefore, according to the brake rubber block 22,22 of the rotational structure of centrifugal force as above ' retardation efficiency and reciprocal winding speed proportionally change, therefore above-mentioned fly net 3 can be crimped onto in the rotating roller 2 in housing 1 with uniform speed naturally.
Now, above-mentioned shell 10 and lid 60 are the constructs that are separated from each other, therefore should be suitable for combining structure each other, preferably, combining structure by bolt assembling is each other stable, and also can be suitable for as required undercutting (undercut) structure, make shell 10 and lid 60 realize each other fastening by pressurization is closely sealed.
In addition, being accommodated in multiple gears in the installation jut 12 of shell 10 can manufacture and utilize from the outstanding independent insertion axle forming of shell 10, to maintain the state rotation of certain binding site, or the inner face of above-mentioned installation jut 12 is manufactured to the curved surface of answering with each gear mesh, these gears are rotated with the directed state of the inner face from above-mentioned installation jut 12, multiple gear as above is in the rotation of the enterprising line stabilization in position separately, as long as interrupter gear 40 is the structures that can move about along slit groove 13 according to the direction of transfer of rotating force, general gear in conjunction with and fixing structure all applicable.
Particularly, as shown in the figure, be accommodated in multiple gear shape in above-mentioned installation jut 12 become with shell 10 directly in conjunction with and the structure that engages, but also can be fabricated to as follows: above-mentioned installation jut 12 separates from shell 10, the built-in brake hoop 11 of side is with flashboard 20 and be connected gear 30 and interrupter gear 40 and actuation gear 50 therein, and what a side of open installation jut 12 was formed as forming in conjunction with lid 60 cuts apart after individual gear-box form, be fixed on shell 10, thereby meet object of the present invention and effect by said method simultaneously.
Therefore, as shown in Figure 7, when the speed reducer of the present invention with combining structure as above launches fly net 3 downwards by user's artificial strength, form according to the rotation of the postive direction of the rotating roller 2 of the expansion power of this fly net 3, the postive direction rotating force of rotating roller 2 is delivered to actuation gear 50 by bindiny mechanism 70, thereby forms the rotation of this actuation gear 50.Now, if above-mentioned actuation gear 50 rotates, its rotating force is delivered to interrupter gear 40, this interrupter gear 40 is according to the rotating force of actuation gear 50, running shaft 42 moves to the direction consistent with the sense of rotation of interrupter gear 40 along slit groove 13, and according to the movement of interrupter gear 40, interrupter gear 40 and the transmission gear 31 that is connected gear 30 become the state of mutual disconnection, therefore according to the non-rotating effect that connects gear 30, can there is not the turning effort to above-mentioned flashboard 20.
Therefore, as mentioned above, when fly net 3 is launched, can not there is the rotation of flashboard 20 downwards, therefore not have consequent decelerating effect completely, thereby realize drawing and launching fly net 3 simple and easyly.
On the contrary, want to make fly net 3 of drawing state as above to rise and when curling, with the compression force of the independent spring assembly of housing 1 combination in rotating roller 2, this fly net 3 is crimped onto in rotating roller 2 in the mode of being pulled on, and rotating roller 2 is now carried out reciprocal turning effort according to the restoring force of spring assembly.
Now, as shown in Figure 8, the reciprocal rotating force of rotating roller 2 is delivered to bindiny mechanism 70 and actuation gear 50, form the opposite spin of this actuation gear 50, same to opposite direction displacement along slit groove 13 according to the interrupter gear 40 of 50 one-tenth engagements of the opposite spin of actuation gear 50 and actuation gear, in the moving process of interrupter gear 40, interrupter gear 40 forms intermeshing state with the transmission gear 31 that is connected gear 30 simultaneously.
Thus, in the rotation of actuation gear 50, form the rotation of interrupter gear 40 and connect the rotation of gear 30 and the rotation of flashboard 20, as shown in Figure 9, according to the rotation of flashboard 20, produce by brake rubber block 22,22 ' outstanding rotating force cause and brake hoop 11 between interference frictional force, its result, suppress rotating roller 2 with high speed and opposite spin, thereby realize the decelerating effect to rotating roller 2.
Now, when the rotational speed of above-mentioned flashboard 20 is fast, brake rubber block 22,22 ' rotary centrifugal force become large in, and the perturbed force between brake hoop 11 increases, deceleration effect increases, and the rotational speed of flashboard 20 is when slow, brake rubber block 22,22 ' rotary centrifugal force relatively diminish, and the perturbed force between brake hoop 11 dies down, deceleration effect reduces, therefore be opposite spin power poor of rotating roller 2 according to the rotating main body that acts on flashboard 20, automatically form the variation of retarding force, thereby fly net 3 can maintain certain speed and slowly be crimped onto in rotating roller 2.
The action of the speed reducer of this structure is with seasonal or that the essential factor such as temperature variation in place is set is irrelevant, and each gear closely engages and drives, therefore can not produce the noise in driving, not only can prevent the collision being caused by the curling action rising rapidly that fly net 3 is carried out, and by changing gear ratio separately, can regulate retardation efficiency.
For example, rotate the situation of 10 left and right and gear ratio is adjusted into No. 1 flashboard 20 of the every rotation of rotating roller 2 and rotate 50 left and right in the case of gear ratio being adjusted into No. 1 flashboard 20 of the every rotation of rotating roller 2, can produce sizable deceleration poor, self-evident, gear ratio is larger mutually, retardation efficiency is just larger, and the rotating roller 2 in the present invention and the preferred speed ratio of flashboard 20 are 1: 30.
Particularly, above-mentioned shell 10 and brake rubber block 22,22 ' utilize identical material to form, can reduce according to same material the abrasion that mutual friction causes, extend its working life, preferably use polyurethane material.; polyurethane material or silicon materials are not only solid; and wear resistance is good, even if therefore produce interference friction each other repeatedly, abrasion also can be very little; therefore extend working life; simultaneously material this in characteristic, there is solid and soft character, therefore can there is not noise that interfering noise each other or impact cause etc., can very quietly move; and when wear resistance is good, there is good frictional force, thus improve to brake rubber block 22,22 ' deceleration effect.
In addition, as shown in figure 10, speed reducer according to the present invention is brake rubber block 22, 22 ' and brake hoop 11 between the corresponding lateral part of grounding parts form the outwards elastic force grounding parts 23 of outstanding form, thereby according to the turning effort of flashboard 20 at brake rubber block 22, when 22 ' generation centrifugal rotation power, first the end of above-mentioned elastic force grounding parts 23 contacts with brake hoop 11 and produces interference frictional force, along with the rotational speed of flashboard 20 increases, to brake rubber block 22, 22 ' centrifugal rotation power increase time, above-mentioned elastic force grounding parts 23 is to brake rubber block 22, 22 ' the compression of interior side direction time, contact area is further strengthened, thereby realize the retardation efficiency of strengthening more.
Thus, can be extended out following feature: in the case of the rotational speed of flashboard 20 increases, therewith proportionally, according to brake rubber block 22,22 ' and brake hoop 11 between the retardation efficiency of interference frictional force be further enhanced.
In addition, as flashboard 20 according to the present invention and brake rubber block 22,22 ' another embodiment of combining structure, as shown in figure 11, form two insertion grooves 26 that mutually depart from a side of flashboard 20, brake rubber block 22,22 ' outstanding the formation and the insertion mechanism 27 of above-mentioned insertion groove 26 correspondingly-shaped of a side end, by by this insertion mechanism 27 and above-mentioned insertion groove 26 combinations, brake rubber block 22,22 ' move about and can carry out the state rotatablely moving of several angle from insertion groove 26 in inserting mechanism 27.Thus, in the time applying rotating force to above-mentioned flashboard 20, according to this rotating force, centrifugal action in brake rubber block 22,22 ', inserting in mechanism 27 rotates from insertion groove 26, form brake rubber block 22,22 ' to inner rotary, by and brake hoop 11 between interference frictional force, produce decelerating effect.
As mentioned above, above-mentioned brake rubber block 22,22 ' applicable various forms and situation and combining structure, in the time that flashboard 20 rotates, as long as can be simultaneously by utilization act on the brake rubber block 22,22 of rotation ' the spin friction power of centrifugal force suppress the rotating force to above-mentioned flashboard 20, any structure is all applicable.
Embodiment and the structure shown in the drawings in as above specification, recorded are only the preferred embodiments of the present invention, do not represent all technological thoughts of the present invention, therefore should be appreciated that and also have various equivalents and the variation that can replace them.
