The specific embodiment

Referring now to Fig. 1, show the gate opening device that can be suitable for opening rotary gate.This gate opening device totally is marked by Reference numeral 1.The general rectangular structure that is provided by outer enclosure 3 is provided gate opening device 1, and this outer enclosure can be by such as the suitable material of plastic material or be made of metal.Gate opening device 1 has output driver 5, and this output driver will drive with arm assembly 7 and be connected (referring to Fig. 3), so that the crank-motion in a known way of rotary gate (not shown).Operator 1 has inner underframe 9, the various parts of this underframe location and support gate opening device 1.Particularly, gate opening device 1 has the motor of installing with respect to underframe 9 11, and motor 11 is used for providing driven by power to power train 13, so that output driver 5 rotations, this output driver makes arm assembly 7 wave then.Motor 11 is preferably the DC motor, yet, do not get rid of and use the AC motor.Usually, the DC motor is 24 volts the DC motor that can change direction of rotation by the pole reversal that applies voltage.Fig. 1 and 2 illustrates the use of user's handle 15 particularly, and this user's handle exposes by the opening in the shell 3 17.Fig. 2 is clearly shown that opening 17 has the structure that slightly is keyhole.Cross side extension in the keyhole provides opening, when rotation user handle 15, can observe mark 19 on user's handle by this opening.Fig. 3 is clearly shown that mark 19 is positioned at the radially two opposite sides of circular user's handle 15.Fig. 1 shows by the keyhole configuration of opening 17 observable, and is depicted as the mark 19 of lock-out state.Opposite mark is represented release conditions.

User's handle 15 is used to make cam rotation, and this cam forms the parts of clutch apparatus (hereinafter to be described), and clutch apparatus allows from motor 11 to output driver 5 to form and drive, and disconnects from motor 11 to output driver 5 driving.

Referring now to Figure 4 and 5, as can be seen, motor 11 is supported with respect to underframe 9 by supporting with housing 21, and housing 21 is around driving shaft 23, and this driving shaft 23 is supported with respect to secondary underframe 25 then.Secondary underframe 25 is connected with underframe 9, but is not clearly shown that in Fig. 4.Describe at Fig. 3, to observe secondary underframe 25 better.Hereinafter will describe in more detail, 5 set up transmission device from motor 11 to output driver.

Turn back to Fig. 4 now, as can be seen, underframe 9 supports output driver 5, makes it spaced apart with respect to medium drive 27.Output driver 5 and medium drive 27 have with respect to underframe 9 and are supported on axle in the roller bearing 29.Medium drive 27 and driving shaft 23 are just in line, and be and coaxial with this driving shaft 23.Driving shaft 23 drives with cone shell 31 and is connected, and cone shell 31 drives rotation along with the rotation of driving shaft 23.Cone shell 31 drives by key 33 then and is connected to medium drive 27.Dog-clutch device (being about to be described) is arranged in the driving shaft 23 coaxially, and allows to drive between driving shaft 23 and the medium drive 27 and separate.Motor 11 has the central main shaft 35 that is connected with worm gear 37 drivings.When worm gear 37 rotations, it makes meshing gear 39 rotations, and therefore this meshing gear makes driving shaft 23 rotations again with respect to driving shaft 23 keyed jointings.Be in the driving engagement state if suppose dog-clutch, then cone shell 31 rotations, this cone shell makes medium drive 27 rotations then.Pinion 41 is keyed to medium drive 27, makes that pinion 41 will rotate with its mode with common driving when middle driver 27 rotates.Pinion 41 makes gear 43 rotation then, and this gear 43 is carried by loosely, is used for rotating freely on output driver 5.The minimum gear that gear 43 has integrally formed with it (perhaps forming and drive interconnection discretely).The external diameter of gear 45 is littler than the external diameter of gear 43.Gear 45 and large diameter gear 47 engagements, gear 47 are mounted on medium drive 27 free axis to rotation.The undergear 49 that gear 47 carryings directly form together with it or form discretely but interconnect with it, this undergear 49 drives output gear 51 then, and this output gear 51 drives with output driver 5 by suitable key pin (not shown) and is connected.

Thereby as can be seen, when dog-clutch is in the driving engagement state, the rotation of the main shaft 35 of motor 11 will be rotated ratio to reduce through power train, thereby output driver 5 will be to rotate than motor main shaft 35 slow speed.Because the rotating speed of the rotating ratio motor main shaft 35 of output driver 5 is low, therefore also will transmit the torque that increases.

Fig. 5 clearly show that the figure that arranges by the drive path of power train.The parts identical with parts among Fig. 4 are established with identical Reference numeral.Fig. 6 illustrates the exploded view of the gear train driver module of Figure 4 and 5, and how the parts that show gear train are assembled in rigid tubular underframe 9.The respective gears 41,47 of jackshaft 27, this jackshaft and roller bearing 29 are assembled in the single gear module in the underframe 9.Similarly, the

respective gears

43,51 of driving shaft 5, this driving shaft and roller bearing are assembled in the single gear module in the underframe 9.Be assemblied in roller bearing 29 in the hole and support axle in the hole of underframe.

In the embodiment shown, each is parallel.Each extends through two holes of the two opposite sides of underframe 9, and these two holes are equipped with roller bearing 29.Should be understood that the alternative that can use roller bearing.For example, can use lining, plastics or the self-lubricating axle collar or any other low friction support.In some embodiments, can be provided for the friction support of axle.

Installation bracket 110 utilizes spiral fastener 127 and nut 126 and is fixed to underframe.During installation, the installation bracket 110 of separation can be fixed on wall, door pillar or other braced structures before the attached underframe 9.This can have the advantage that is easy to install with setter safety.For example, independent Support bracket than underframe and carriage in conjunction with light, therefore, independent carriage is easier to remain on correct position, so that carriage is fixed to support member.It is soldered or for good and all be fixed to installation bracket 110 to be used for the bolt 128 of attached underframe 9.Because the friction between the hole in bolt 128 and the flange 111, therefore, bolt 128 formation can be supported on support member on the installation bracket with underframe 9 by these bolts 128 only.Flange 111 can be integrally formed with underframe 9, for example by cutting the flange profile from an end-grain cutting of the pipe that is used to form underframe 9 and crooked cutting part forms each flange 111.Alternatively, flange can be the resolution element that for example is connected by welding to underframe 9.

Even utilizing before bolt 128 and nut 126 be fixed to Support bracket with underframe, the weight of underframe and Assembling gear etc. also is supported on the Support bracket.This has the advantage that easy operating is installed.Because setter need not support the weight of underframe and Assembling gear when being fixed to carriage at the installation Support bracket and with underframe, so this can reduce the risk of pulling.

Support bracket at first is installed to be installed underframe then and also can reduce the possibility that dust and sand grains etc. enter gear train.For example, be used for bracket support can be produced dust and spun yarn to the boring securing member of concrete or brick wall.Utilize the installation bracket that separates to remove any dust and sand grains before underframe and the gear that is associated are attached to installation bracket 9c, therefore, reduction dust and sand grains enter the possibility in the gear.

When fitting operation device 1, installation bracket 110 is fixed on wall or other structure.In case assemble fully and install, just use tab 120 and nut 125 will cover 3 and be fixed on the operator.

Power train module as shown in Fig. 4 to 10 avoids having the inside underframe 9 that is manufactured into accurate specification, because can process the hole that is used for back shaft easily, therefore, axis is with keeping parallelism.Alignment issues can make can not assemble power train module, and perhaps power train module can be assembled but has unacceptable recoil level or play level between gear.The tubulose underframe of rigidity has reduced the unsuitable axially aligned risk of the central axis of the axle of the various gears of support in assembly.

Axially align or problem that unacceptable play level produces is included in and may causes the unacceptable amount of exercise of barrier in response to the unacceptable motion of external force between friction, vibration and the parts unnecessary between unacceptable noise level of operating period, the parts because of relatively poor in the pinion unit module of prior art.Problem such in the prior art can be increasingly sharpened, and relevant fatigue can cause the gear train module to lose efficacy very early.For example, blocking owing to parts excessive wear, underframe fracture or gear.Known is that the underframe manufacturing issue of prior art has caused these problems.Yet some in these problems also may have other reason.

The utility model is that the gear train driver module of feature has overcome these problems of the prior art by providing with firm integral type tubulose underframe.Firm integral type tubulose underframe 9 can be formed by the extrusion metal such as aluminium or steel.This metal can be squeezed into the pipe with expectation cross section that is used for underframe, cuts then to form underframe.Alternatively, underframe can form integral type tubulose underframe by one or more pieces metal bendings (if desired) and welding.For example, two " U " shape cross section slice of extrusion metal can be welded together, perhaps keep rigidly to form the integral type underframe.Alternatively, can and weld the metal sheet bending to form the integral type underframe.Other alternative embodiment that is used to construct the underframe expectation comprises with technical grade plastics or metal module and forms the integral type underframe.

In the embodiment shown, underframe is roughly rectangular cross section.Yet, also can be other cross section.For example, can use polygon cross section, oval cross section or in conjunction with the mixing cross section of smooth and curved edge.This optional cross section can be used to power train module that particular appearance is provided, and presents the functional advantage of rigidity integral type underframe.

In the embodiment shown, first hole is formed in first side of underframe, and second hole is formed in underframe and second side first side thereof opposite.This is for such underframe is provided, and this underframe is applicable to motor is connected to medium drive on the side of this underframe, and will drive on another side that efferent is connected to underframe.Yet, can be other layout.For example, motor and driving connecting portion can be formed on the side of underframe.Alternatively, motor can form adjacently with driving to be connected, rather than is formed on opposite two sides of underframe.Should be understood that any feasible layout all drops in the scope of the present utility model.

The advantage that should be understood that the integral type tubulose underframe 9 of rigidity is to have the underframe of the character of integral type tubular structure, and the sidewall that this underframe has firm rigid structures and accurately limited, these sidewalls are relative to each other fixing and firmer.In addition, integral structure is avoided and each slice groups of underframe need be fitted together.This is avoided forming the Probability Area of manufacturing tolerance then, manufacturing tolerance for example is to be used for the position of related features of joint between two chassis components and to be present in the tolerance of joint self, such as the size in the hole in the chassis component be used to pass hole poor with between the securing member that is connected each part.

Another advantage of the integral type tubular structure of underframe 9 is to reduce the site error and the alignment error in the hole that is used for receiving axes.For example, be set in the hole under the situation of two sides of underframe, be easier to guarantee the aligning of these holes in the underframe of the tubular structure of integral body than underframe with separating component processing.This can produce because of making processing, is drilled with the hole that matches in line such as drilling by single.

Shown embodiment uses two groups of meshing gears, and one group is carried on the driving shaft 5, and another group is carried on the jackshaft 27.In some embodiments, other jackshaft can be set.The quantity of jackshaft can be based on being used for from the gear configurations of the rotation ratio of expectation is provided between the input of motor and the driven efferent.For example, the meshing gear structure can use three groups of above gears, and every group all needs independent axle.The tolerance sensitivity that should be understood that power train module can increase with the group number of meshing gear, therefore uses integral type tubulose underframe may even more to help having the gearbox module of plural jackshaft.

Referring now to Figure 11, the nearly sight that shows dog-clutch is arranged.Figure 11 clearly show that driving shaft 23 has the central hollow hole of admitting "T"-shaped drive pin 53.Drive pin 53 has and limits "T"-shaped shape body 55 and cross head 57 together.The right-hand member side of driving shaft 23 (when observing Figure 11) has the big footpath hole portion 59 that admits compression spring 61.Packing ring and snap ring 63 will compress spring 61 and remain in the hole 59, and along the head 55 that promotes "T"-shaped drive pin 53 towards the direction on right side, make in the receiving slit (not being clearly shown that) in its bottom that enters cone shell 31.Therefore, under the state of the groove of the downside that is positioned at cone shell 31 at head 55 shown in Figure 11, driving can be delivered to cone shell 31 from driving shaft 23, and is delivered to other parts in the power train then.When being moved to the left when the bias voltage of "T"-shaped drive pin 53 opposing compression springs 61, head 55 will shift out from groove, and disconnects from driving shaft 23 to cone shell 31 driving.This layout provides the dog-clutch that is used for the room door opener, to disconnect or to connect from motor 11 to output driver 5 driving.

Figure 11 is clearly shown that meshing gear 39 is contained in the housing 65 that remains in secondary underframe 25 tops.Driving shaft 23 is supported in the bearing in the housing 65.User's handle 15 forms the part of clutch actuators, and this clutch actuator influences the operation of "T"-shaped drive pin 53, to allow from the motor to the output driver 5 driving or to disconnect this driving.Here, as can be seen, user's handle 15 is the circular discs with interior handshake part 67.User's handle 15 is connected with axle 69, and this axle 69 is connected with cam 71 then.Axle 69 is supported with respect to another secondary underframe 73 again, and secondary underframe 73 is installed in housing 65 tops.The rotation of axle 69 is vertical mutually with the rotation of medium drive 27 and "T"-shaped drive pin 53.Cam 71 is mounted to just with the free end that projects upwards of "T"-shaped drive pin 53 and engages.The configuration of cam 71 makes that cam 71 will not close with the external freedom termination of "T"-shaped drive pin 53, as shown in figure 12 when user's handle 15 is in the position.When user's handle 15 rotates about 180 °, cam action and " T is " on the free end of shape drive pin 53 by being pressed in, to overcome the biasing force of compression spring 61, and the groove of cross head 55 from the soffit of cone shell 31 shifted out, therefore interrupt by power train driving of 5 from motor 11 to output driver.

Can make amendment under the situation that does not deviate from scope of the present utility model, character of the present utility model is stated clearly fixed in the past.
