Description of drawings
For above-mentioned purpose of the present invention, feature and advantage can be become apparent, below in conjunction with accompanying drawing the specific embodiment of the present invention is elaborated, wherein:
Figure 1A, 1B illustrate the elevator scheme drawing with rack-and-gear lift system of one embodiment of the invention.
Fig. 2 illustrates the rack-and-gear lift system decomposing schematic representation of one embodiment of the invention.
The specific embodiment
The present invention is the power bi-shunting form that adopts in the gear case of elevator out of doors, utilize a motor shaft to drive two identical output gears simultaneously, when one of them output gear can't mesh fully owing to running to the standard knot junction between tooth bar and tooth bar, by the double split flow load balancing mechanism, regulate the engagement of output gear wheel and rack, make the stand under load equalization of gear case.
Figure 1A, 1B illustrate the elevator scheme drawing with rack-and-gear lift system of one embodiment of the invention.Wherein Figure 1A is a front view, and Figure 1B is a lateral plan.Elevator 1000 has rack-and-gear lift system 100, electrical motor 200, electric cabinet 300 and lift car 400.Contain the electric component that is useful on the operation of control elevator in the electric cabinet 300.Electrical motor 200 is via its motor shaft 201 outputting powers, and passes to rack-and-gear lift system 100, and rack-and-gear lift system 100 is by rack drives lift car 400 action of upgrading.
Above-mentioned rack-and-gear lift system 100 comprises power dividing parts, first drive disk assembly and second drive disk assembly.The output shaft 201 of electrical motor 200 is couple to the power dividing parts by first gear 103, and first gear 103 is a miniature gears.In one embodiment, electrical motor 200 configurable frequency converters are realized the adjustment of rotating speed.
The power dividing parts are made of second gear 111, the first shunting gear 112, the second shunting gear 113 and first transmission shaft 114, second gear 111, the first shunting gear 112, the 4th gear 113 all are located on the transmission shaft 114, wherein second gear 111 is a big gear wheel, itself and first gear 103 mesh, and realize first order deceleration.The first shunting gear 112 and the second shunting gear 113 are evenly exported the power of electrical motor 200 at the two ends of transmission shaft 106 respectively, and the first shunting gear 112 and the second shunting gear 113 are miniature gears.
First drive disk assembly is made up of the 3rd gear 121 and transmission shaft 122, second drive disk assembly is made up of the 4th gear 131 and transmission shaft 132, wherein the 3rd gear 121 and the 4th gear 131 are big gear wheel, with the first shunting gear 112 and 113 engagements of the second shunting gear, realize second stage deceleration respectively.Power is passed to first output gear 123 and second output gear 133 via transmission shaft 122,132 simultaneously.
In an embodiment of the present invention, first drive disk assembly and second drive disk assembly as the transmission device between the first shunting gear 112 and the second shunting gear 113 and first output gear 123 and second output gear 133, can be realized certain reduction ratio respectively.According to the needs of elevator operation, first drive disk assembly and second drive disk assembly are provided with the different gear numbers of teeth or gear mesh structure, so the present invention is not limited to the above embodiments.
During the work of said gear tooth bar lift system, power is by motor shaft 102, first gear 103, be divided into two-way branch then and transmit, in the 1st branch, power is by second gear 111, the first shunting gear 112, in the 3rd gear 121 and first output gear, 123, the 2 branches, power is by second gear 111, second shunting gear 113, the four gears 131 and second output gear 133.First output gear 123 and second output gear 133 mesh with tooth bar 140 simultaneously.
Now by the traditional gear mechanism of description shown in Figure 1, traditional pinion and rack has only single output gear (for example second output gear 133) and tooth bar 140 engagement operations, out of doors on the elevator, because the accumulation location tolerance between the tooth bar standard knot is bigger, often occur as the situation of tooth bar 141 with tooth bar 142, when gear 133 when running to the junction of tooth bar 141 and tooth bar 142, wheel and rack can produce in the engagement transition beats, because the processing of tooth bar length restriction, cause the load of output gear inhomogeneous, thus violent vibrations and the noise of generation that continues.
And the present invention is owing to adopted the double split flow gear case to pass through load balancing mechanism, when second output gear 133 runs to the junction of tooth bar 141 and tooth bar 142, first output gear 123 is normal operation on tooth bar 141 still, though this moment two output gear wheel and racks engagement situation difference, but two output gears 123,133 affact load on the transmission shaft 114 at the first shunting gear 112 and the second shunting gear, 113 places simultaneously, this transmission shaft 114 adopts floating type mounting means, so be in operation, can carry out moving of axial direction automatically, final realization gear all carries, thereby has guaranteed whole elevator smooth running at work.
Elevator also uses frequency converter to control the real-world operation speed of elevator when adopting the double split flow gear case, by the number of teeth of distribution gear and the frequency of motor, thereby satisfies elevator operating needs under the various working.
In sum, elevator of the present invention has adopted the rack-and-gear lift system of double split flow, thereby realizes that outdoor elevator all keeps low noise in the operation overall process, few vibrations, the super performance of smooth running and ride comfort.Evidence, the noise that produces in the forced stroke of outdoor elevator of the present invention in 100 meters is 75 decibels, effectively reduces the noise of elevator operation.In addition, the elevator safety of the present invention also elevator than general individual gears lift system is good, and power is through after the double split flow, and the load that each branch bears all is original 50%～60%.
Though the present invention discloses as above with preferred embodiment; right its is not in order to qualification the present invention, any those skilled in the art, without departing from the spirit and scope of the present invention; when can doing a little modification and perfect, so protection scope of the present invention is when with being as the criterion that claims were defined.
