Description
Technical field
The present invention relates to a kind of passenger conveying equipment, relate in particular to a kind of escalator or movable sidewalk with an operation band.Described passenger conveying equipment is by forming with the lower part: a support; One is installed in the main operation band actuating device on the described support, and this device has an axle drive shaft, has at least an operation band drive wheel to be connected in described axle drive shaft; One is used to drive the driver element of described main operation band actuating device, and there are a drive motor and a reduction gear apparatus in this unit, and the output of this reduction gear apparatus is connected in the input of described main operation band actuating device.
Background technology
Many these type of passenger conveying equipments are using now.The operation band is represented passenger's delivery element of passenger conveying equipment.The passenger stands or walks on the outside face of operation band, and then is transferred.For escalator, described operation band also refers to the ladder band.This ladder band is made up of a plurality of ladders, by a ladder chain described ladder is linked together one by one.One main operation band actuating device is arranged at one of them location of operation band commutating zone usually.This main operation band actuating device typically, has two sprocket wheels that are used to drive described operation band.This main operation band actuating device is by a drive unit drives.
For movable sidewalk, described operation band is formed by connecting by supporting plate one by one, thereby in the case, described operation band then refers to a kind of supporting plate band.These supporting plates link together one by one by being similar to the such conveyer chain of escalator, and are driven by a main operation band actuating device.Yet, the also movable sidewalk of forming by rubber-like material such as reinforced plastics comparatively speaking by operation band, this material that is to say do not have single ladder or supporting plate in this case along moving strip length direction integral extension.These movable sidewalks are also driven by a main operation band actuating device that is arranged at one of commutating zone usually.
The driver element that is used for main operation band actuating device has a drive motor usually, and the first order of a reduction gear apparatus directly links to each other with this motor.The brake equipment of passenger conveying equipment also is usually placed in the zone of drive motor.Drive motor is installed on the support of passenger conveying equipment with the reduction gear apparatus first order usually.The output of the first order of reduction gear apparatus drives main operation band actuating device by so-called breast wheel.This breast wheel is generally a sprocket wheel or a Knucle-gear.Because breast wheel need be crossed over certain distance usually, thereby is easy to realization with sprocket wheel, that is to say, cross over required separation distance easily with a long slightly chain.The breast wheel that is designed to Knucle-gear has several usually, and their sizes are the same, thereby need not gear reduction.Sprocket wheel is applied to usually so-called " department store system ", for example in the department store, the system that locates to use such as supercentre, shopping arcade or office building.So-called " traffic system ", as be applied to the public transport region of occasions such as Railway station, airport and subway station, need higher requirement be arranged than commercial applications.The breast wheel of Knucle-gear form is mainly used in " traffic system ".
There are some defectives in all these known systems.At first, a series of single parts need mutually positioning and are installed on the support respectively.Especially the drive motor separation is installed on can be directed on the support and produces additional vibratory on support, and the result produces undesirable noise.Being installed separately also has each parts need distinguish the shortcoming of adjusting each other, and this can increase assembly cost, that is to say, the power of striving affects adversely unexpectedly.
In addition, each independent parts need each independent housing respectively.This can cause: the material that needs are extra increases cost.
Summary of the invention
Therefore, the present invention is based on following purpose: design a kind of passenger conveying equipment of describing that starts, it can avoid giving support the transfer of vibration of drive motor, be easy to make, and manufacturing cost is not high.
According to the present invention, its goal of the invention realizes by following scheme.A kind of passenger conveying equipment, be characterized in: drive motor is installed on the casing of reduction gear apparatus, drive motor and reduction gear apparatus form a driver element, this driver element is supported by main operation band actuating device, and more satisfactory ground also integrates brake equipment with driver element, for example, can be arranged in brake equipment between drive motor and the reduction gear apparatus, it can be one fen part of opening, and also can become one with drive motor or reduction gear apparatus.
If the present invention is compared with the structure of prior art, people can be very easy to find: only need a driving device to replace two reduction gear apparatuss that separate just can realize easily that whole gear system slows down.Drive motor is installed on the casing of described driving device.In this case, as true needs, brake equipment can be arranged between this reduction gear apparatus and this drive motor.The result is: need not drive motor to be directly installed on the support, thereby the vibration meeting of passing to support significantly reduces again.Reduction gear apparatus, drive motor, also have brake equipment and then form the driver element of one as needs.The driver element that to also have characteristics are described one is directly supported by main operation band actuating device.Driver element can give and be assembled into parts.This driver element be need not special adjustment.Specifically, this driver element can design like this, and promptly the casing of reduction gear apparatus is the end protective case of drive motor rotor simultaneously, and in the case, if the casing of reduction gear apparatus is the casing of brake equipment simultaneously, then advantage is more outstanding.Selectively, the casing of drive motor can be connected with the casing of reduction gear apparatus by traditional Connection Element.When the assembling passenger conveying equipment, whole driver element can be installed on the main operation band actuating device.According to the type of installing, only need little adjustment or need not adjust, just as following more detailed description.
Comparatively it is desirable to: driver element is supported by the axle of main operation band actuating device.For example, can make the axial gear teeth on the axle of main operation band actuating device, the gear teeth are meshed with the output of reduction gear apparatus.Like this, driver element only is pulled on the axle of main operation band actuating device basically, and connect in the mode of for example screw or key firm, thereby locking.
Selectively, for example can be connected to the casing of driver element rigidly on the supporting construction of main operation band actuating device with screw.In this structure, need certain calibration adjustment, so that the energy of drive motor can successfully be delivered to main operation band actuating device through reduction gear apparatus.For example, do not adjust correctly if reduction gear apparatus was calibrated when installing to master's operation band actuating device, that cooperation adjustment that will be directed between the rotating part is bad, and then wearing and tearing increase.Contrast with a situation about supporting of driver element by main operation band actuating device, this structure needs certain adjustment.
More satisfactory ground, torque support is arranged between the support and driver element of passenger conveying equipment.For example, torque support can begin at reduction gear apparatus casing or drive motor place.Especially only need torque support in the structure that supports by main operation band actuating device at driver element.Yet because the long arm of force is arranged, this structure Design also has its advantage: driver element also can be connected on main operation band actuating device such as its supporting bracket.Torque support also can directly be connected on the support of passenger conveying equipment.Yet this connection also can be realized indirectly in the mode that parts are installed between the two.Under the situation of special case very, also differently design torque supports.If need really, can be connected to the building that is used to install passenger conveying equipment to torque support.
Comparatively ideally provide a kind of elastomeric torque support.For example, this torque support can be made up of traditional bump leveller or coil spring bump leveller.These bump levellers are used in the auto-industry in large quantities as them.Especially think favourably of this parts when considering cost.Poly-mer vibration isolator, rubber shock absorber or all can be considered by the vibration isolator that other suitable elasticity material is formed are to satisfy this purpose.
More satisfactory ground, reduction gear apparatus can be formed by gear system.Usually the gear system ratio is more suitable for transmitting high load capacity.In addition, they do not need too many maintenance.This point advantage especially for integrally-built driver element.Especially the most handy three grades deceleration wheel word.Only reduction gear apparatus is made up of a reduction gear apparatus by three grades, its first order is the bevel-gear pair of the axial change that will rotate 90 degree, its second and third level is the commutating tooth wheel set, locating axial rotary at second and third grade does not change, that is to say that axial rotary only is converted into another level from one-level in a parallel manner.
For realizing required driving device reduction ratio, the reduction gear apparatus that includes three grades especially has advantage.The conventional drive motor is the typical rotating speed of four phase asynchronous dynamos for example, when line frequency is 50Hz, is approximately 1500rpm.When line frequency also was 50Hz, six mutually asynchronous rotating speed of motor were approximately 1000rpm.Be approximately 10rpm owing to drive the hope rotating speed of main operation band actuating device, therefore the reduction ratio of required wheel word is approximately 120: 1.One comparatively ideal reduction gear apparatus includes: a reduction ratio is approximately 6: 1 bevel-gear pair, and it is as the first order; The first order that spur gear slows down, its reduction ratio is approximately 4: 1; The second stage that spur gear slows down, its reduction ratio is approximately 6: 1.Consequently total reduction ratio is approximately 120: 1.Finishing bevel gear cuter is preferably the double curved surface screw bevel gear, perhaps is the finishing bevel gear cuter of other any kind.
As selectable scheme, reduction gear apparatus also can be the combination of a sprocket transmission device or gear system and sprocket transmission device.
The casing of reduction gear apparatus better is divided into different chambers, so that can use different lubricating oils for different levels.Obviously, high speed gear needs the more lubricating oil of good quality than low speed gear.Similarly, there is the gear of high-energy-density to need corresponding more premium-quality lubricating oil.For example, lubricate low speed gear through grease commonly used, high speed gear is then used oil lubrication preferably.If all grades use identical lubricating oil, then should determine the quality of lubricating oil and the replacement cycle of lubricating oil to require the highest level.If the casing of reduction gear apparatus is divided into different chambers, just can select a kind of proper lubrication oil for each chamber.Because this measure, the quantity of required expensive high-quality lubricating oil will significantly reduce.The oil change cycle of two chambers can be complementary each other, finally can not produce the result of additional expenditures for maintenance by selecting suitable chamber size and coupling lubricating oil, can obtaining.
Design preferably is: for first and second level provides a chamber, for the third stage provides second chamber.
Comparatively ideally be: the separate modular that contains the reduction gear apparatus first order and drive motor respectively can be connected to wheel chain last also be on the gear of reduction gear apparatus outgoing position.If for first and second level provides a chamber and for the third stage provides second chamber, this point just can realize in a kind of very simple mode.Can be connected to selection on the wheel chain final gear to the several separate modular that contain the drive motor and the reduction gear apparatus first order, make the driver element that just can realize satisfying the passenger conveying equipment of virtually any size with several identical parts only, the just so-called modular concept of foundation.Obviously, lack passenger conveying equipment needs still less the driving energy of the passenger conveying equipment of delivered length or low delivery head than long delivered length or high delivery head.Remain till now: the drive motor of different capacity is used for different power needs, makes the gear of different size for every kind of power of drive motor, and the production of these parts correspondingly can increase cost with storage.The modular design of being recommended according to the present invention, make and only use two kinds of different parts, promptly be positioned at casing and the last gear of the wheel chain of several connection modes arranged and have the module of the reduction gear apparatus first order and drive motor, just can realize satisfying the driver element of any power needs of passenger conveying equipment.
More satisfactory ground, the driving of reduction gear apparatus are connected on the axle of main operation band actuating device.
Way is preferably: the final gear of wheel chain is directly connected on the band drive wheel of main operation band actuating device.This specific design has following advantage: under the situation of special case very, the final gear of wheel chain can become one with the band drive wheel of main operation band actuating device.Because two elements usually have identical diameter, thereby adopt this measure can make its manufacturing become simple in many cases.
The present invention also relates to a kind of driver element that is used to have the passenger conveying equipment that moves band, it has a drive motor and a reduction gear apparatus that links to each other with main operation band actuating device, and the characteristics of described driver element are that drive motor is installed on the reduction gear apparatus.
