Asynchronous dynamo joins that the towing machine that worm and gear slows down is low because of its cost, stable performance occupies larger proportion on market, but this towing machine complex structure, part are many, and volume is big, Heavy Weight; Drive motor is an asynchronous dynamo, and efficient is low, and power factor is low, and is not energy-conservation; The power factor of asynchronous machine is low, requires the capacity of controller big; The requirement on machining accuracy of worm and gear is higher, the tooling cost height; Worm and gear gearing friction resistance is big, and driving efficiency is low, wastes energy; Overall volume is huge, is difficult to be applied in the Machineroom-less elevator system.Just because of the existence of above-mentioned defective, the towing machine of the type is replaced by the higher permanent-magnet synchnorous gearless dragging machine of efficient just gradually at present.
Permanent-magnet synchnorous gearless dragging machine more and more widely is used, and becomes the towing machine type of main flow gradually.The towing machine of the type uses permagnetic synchronous motor direct drive traction sheave, saves the gear change link, has saved volume and weight.But the drive motor of this towing machine belongs to the low speed high torque motor, and volume is big, and Heavy Weight is not high with respect to its power density of high-speed electric expreess locomotive, and needs expensive material such as copper cash and magnet steel more, has increased overall cost; This motor shaft end directly carries the loading of dangling of car and counterweight, requires motor supports that enough intensity will be arranged, and this has increased the cost of casing, axle and bearing; Because rotating speed of motor and frequency are lower, for the elevator motion system is carried out accuracy control, need to use the position transduser (coder) of high-resolution, this has also increased cost; For brake system, braking force acts directly on the parts that slowly run, and required braking force is big, and the volume of brake part is big, Heavy Weight; For satisfying equipped in addition handwheel of laws and regulations requirement needs and jiggering gear, increased extra cost; Though the towing machine of the type can be used in no machine room and small room, but be not suitable for hanging than in 1: 1 elevator device, mainly be applicable to and hang than in 2: 1 the elevator device, but hang than the cost of hoist ropes in 2: 1 the elevator device and track adjusting wheel than 1: 1 elevator device height a lot.
Except that two above-mentioned class towing machines, the towing machine of speed reduction gearings such as helical wheel or planetary wheel appears having in some document.Through patent retrieval, the towing machine that utility model patent " traction machine with permanent-magnetic electric machine drive gear " (application number CN200820186335.7) is mentioned is to use permagnetic synchronous motor in conjunction with turbine and worm decelerator, though this towing machine has used the higher permagnetic synchronous motor of efficient, but still exist the worm and gear driving efficiency low, defective such as volume is big; Patented invention-creation " permanent magnetic synchronous arm rest lift traction machine " (application number 200710144004.7), all mention in patented invention-creation " cargo lift tractor " (application number 200610155079.0) and the utility model patent " arm rest lift traction machine " (patent No. ZL 200620092267.9) and use helical wheel to carry out deceleration transmission, but these towing machines all are furnished with a cover drop-gear box, need to process at least one cover low speed big gear wheel in addition (such as helical wheel, dish gear and bevel gear etc.), these Gear Processing are taken higher, noise can be bigger when gear had deformation, in addition, handwheel is also wanted in addition processing separately, can not be shared with the gear in the speed reduction gearing, so such towing machine complex structure, the space is dumb, and not too is fit to no machine room.Patented invention-creation " elevator traction machine " (application number 200410062097.5) and patented invention-creation " elevator traction machine " (application number 200480041519.9) are all mentioned the employing planetary gear speed-reduction, but this drive mechanism gearing noise is big, the tooling cost height.In a word, though the towing machine in above-mentioned patent all relates to speed reduction gearing, all inequality with the structure and the effect of the invention.
The innovation and creation content
The purpose of the invention is: a kind of compact conformation is provided, and cost is low, the efficient height, and the geared machine that has speed reduction gearing of energy-conserving and environment-protective can solve the above-mentioned technical matters that known towing machine exists effectively.
The technical conceive of the invention is: the speed change transmission by between traction sheave and motor, and rotating speed of motor is raised, torque reduces, thereby improves the power density of motor, improves the efficient of system.Described big gear wheel, traction sheave, jiggering gear can become one, and compact conformation can be saved the volume and weight of towing machine.
The technical scheme of the invention provides a kind of motor, traction sheave, brake equipment, speed change transmission big gear wheel, speed change transmission towing machine of miniature gears and bracing frame that comprises, it is characterized in that described big gear wheel and traction sheave are fixed as one, and can be as a coaxial synchronous rotation of integral structure component, the axostylus axostyle of this integral structure component is supported on the bracing frame of towing machine; Make the rotating speed of rotating speed of motor by the transmission of power between described big gear wheel and the miniature gears greater than traction sheave.
A notable feature of the technical program is that described speed change transmission type is the non-again planetary gear speed-changing transmission of non-worm and gear speed change transmission, neither directly use known gear case to carry out speed change, but the speed change transmission is fixed as one by modes such as casting, welding or bolt ups with big gear wheel and traction sheave, become a unified integrated morphology part, this framing member do as a whole can either traction or Wound steel rope, can carry out the speed change transmission with the miniature gears interlock of motor side again, even can also be used for the jiggering operation as the jiggering direct geared.As seen, it structurally is the characteristics of coaxial swivel that the technical program has been utilized speed change big gear wheel and traction sheave, integrate the part that they can be shared, two script independent structures parts---the speed change transmission is integrated into an integral structure component with big gear wheel and traction sheave in traditional towing machine, compact conformation, saving in material and cost.
Towing machine in the technical program has speed-changing mechanism, and its variable speed type can be the transmission of one-level speed change, promptly by and the big gear wheel of traction sheave rotation synchronously and and the miniature gears of machine shaft rotation synchronously between directly gear mesh realize transmission of power; It also can be the transmission of secondary gear speed change, be that described big gear wheel and described miniature gears do not mesh, but by an other cover intermediate gear as intermediate transfer link transferring power indirectly between described big gear wheel and described miniature gears, this cover intermediate gear is meshed with described big gear wheel and described miniature gears respectively.Except that gear transmission, the power delivery mode in the technical program can also be a linked transmission, and promptly chain is meshed with described big gear wheel and described miniature gears respectively, as intermediate link transferring power betwixt.
In above-mentioned speed-changing mechanism, the radius of rotation of motor shaft end miniature gears is less than the radius of rotation that is fixed in the big gear wheel on the traction sheave, and behind gear transmission, rotating speed of motor is greater than the rotating speed of traction sheave.According to the electric machine design theory, the motor of equal-wattage, rotating speed high torque (HT) more are just more little, and motor volume and weight are also more little, and electrical efficiency is also high more, so the no-load voltage ratio of above-mentioned speed-changing mechanism is big more, motor speed is high more, and the cost of motor is just low more.
When maintenance and installation exercise, sometimes need under powering-off state, move up and down car by manpower, this need design barring mechanism on towing machine, a feature in the technical program is exactly that the big gear wheel used of described speed change transmission can be used as the jiggering gear, and manpower rotates big gear wheel by the jiggering handle and just can drive car and move up and down.In addition, double geared towing machine mentioned above, that the secondary intermediate gear that is meshed with the motor shaft end miniature gears also can be used as the jiggering gear, is used for the jiggering operation of elevator, and the jiggering handle that the jiggering operation time is used for applying manpower also can be integrated in this jiggering gear.As seen, the jiggering gear that big gear wheel that transmission is used in the technical program and jiggering are used is same framing member, structurally unites two into one, and two independent structures parts of script are integrated into a framing member in promptly traditional towing machine in the technical program.
