Description

Escalator driving host
Technical field
The utility model relates to the elevator technology field, especially a kind of machine that is used to drive staircase motion, band reduction gear apparatus.
Background technology
Existing escalator driving host be by an electrical motor as propulsion source, the output shaft of this electrical motor is connected with a worm type of reduction gearing after through a drg, the output shaft of its worm type of reduction gearing is the axle drive shaft that drives escalator.In use, this axle drive shaft drives the staircase motion by a chain gearing.Owing to there is the relative motion of phase mutual friction in the worm type of reduction gearing between the worm and wheel, therefore, driving efficiency is low, when inversion driving, its driving efficiency is lower, therefore, the staircase driving host power consumption of this structure is bigger, and the energy of these frictional losses also can convert heat to and cause parts rising temperature, thus the aggravation wearing and tearing, the reliability and the service life of reducing machine run.
The utility model content
Problem to be solved in the utility model provides a kind of driving efficiency height, reliable escalator driving host.
In order to address the above problem, this escalator driving host also includes electrical motor and is contained in motor output shaft to the drg between the change speed gear box input shaft, the input shaft of described change speed gear box connects by the input shaft of a pair of cone gear with the planetary gearbox that is contained in this change speed gear box, and the output shaft of this planetary gearbox is the Power Available Shaft of escalator.
On the basis of technique scheme, described cone gear can be the cone gear of hyperbolic-type, can directly be made as the initiative taper generating gear in the described a pair of cone gear in the inner of described change speed gear box input shaft; A gear as the sun wheel of described planetary gearbox also can directly be made in the inner of the input shaft of described planetary gearbox; The inner of the output shaft of described planetary gearbox can make the planetary carrier that becomes described planetary gearbox.
In above-mentioned various technical schemes, the input shaft of described change speed gear box can be inlaid in the power input hole of described gear box casing by bearing and bearing seat, described planetary gearbox also can be inlaid in the takeoff output hole of described gear box casing, and a bearing of this planetary gearbox input shaft is contained in the bearing seat of described planetary gearbox, another bearing of this planetary gearbox input shaft is contained in the bearing seat that is fixedly connected in the described gear box casing mounting hole, this structure be convenient to install with use in maintenance.
Staircase driving host of the present utility model is compared with the main frame of traditional escalator, and following beneficial effect is arranged:
1, adopted finishing bevel gear cuter to rotate and the technical program of epicyclic reduction gear transmission is compared with the technical scheme of traditional worm type of reduction gearing transmission, it is 96% that the rotating driving efficiency of the technical program gear system can reach 98% left and right sides net effciency respectively, and the driving efficiency of traditional rotating direction with double end worm and gear staircase driving machine only is respectively 61% and 45%, thereby mechanical efficiency can promote more than 30%.
2, because the drive technology that adopts hyperbola bevel-gear pair and planetary gear reducing mechanism to be combined into substitutes traditional worm and gear drive technology, not only energy-conservation, and can avoid the wearing and tearing that gear heated up aggravate because of frictional heating, thereby can improve the service life and the reliability of operation of driving host.
3, adopt the cone gear of hyperbolic-type in the cone gear transmission device, can effectively improve gear meshing performance and load-carrying capacity.
4, driving gear is directly made in the inner of change speed gear box input shaft, the sun wheel of planetary gearbox is directly made in the inner of the input shaft of planetary gearbox, the inner of the output shaft of planetary gearbox is the planetary carrier of described planetary gearbox, not only can reduce connecting link and be convenient to installation and maintenance, but also can guarantee the driving efficiency that inter-stage connects, improve the reliability of machine run.In addition, the input shaft of change speed gear box is inlaid in the power input hole of described gear box casing by bearing and bearing seat, described planetary gearbox is inlaid in the takeoff output hole of described gear box casing and a bearing of planetary gearbox input shaft is contained in the bearing seat of described planetary gearbox, another bearing is contained in these structures that are fixedly connected in the described gear box casing mounting hole bottom bracket, all helps the installation and maintenance of machine.
5, planetary wheel and bevel drive mechanism are in transmission process, has bigger rotor inertia, thereby can run under the situation of outside dead electricity for the drg staircase is in operation, by the unexpected band-type brake of electromagnet, provide more favourable pulsation-free even deceleration stop distance, the rotor inertia of enough big necessity is provided.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with the accompanying drawing example:
The electrical motor 1 of escalator driving host shown in Figure 1 is connected with gear box casing 11 by connecting two-way flange 2, the drg that is made of brake wheel 22 and damper brake 23 is housed in two-way flange 2, and drg connects with the input shaft 17 of change speed gear box by coupler 20.
Change speed gear box is made of with planetary gearbox the first order transmission device that gear box casing 11 and a pair of cone gear constitute.First order transmission device is made the change speed gear box of initiative taper generating gear by the inner input shaft 17, bearing 18, bearing seat 19 and driven cone gear 13 constitute, in the fitting process of making, input shaft 17 is linked to be an integral body by bearing 18, bearing seat 19, and setting-in is gone in the power input hole of gear box casing 11 together then.Planetary gearbox made the input shaft 16, planetary wheel 4 of the planetary gearbox of sun wheel by the inner, as the power take-off shaft 8 of planetary carrier, planet wheel spindle 5, gear ring 3, bearing 7,9,12, formations such as the bearing cap shim 6 of band seal ring and bearing seat 10.Planetary wheel 4 wherein, power take-off shaft 8, planet wheel spindle 5, gear ring 3, bearing 7,9,6 of the bearing cap shims of band seal ring and bearing seat 10 become one by the bolt binding when assembling, and whole setting-in is gone in the takeoff output hole of gear box casing 11.The input shaft 16 of planetary gearbox and the dress thereon bearing 12,15 and the driven cone gear 13 of first order transmission device do as a whole in the mounting hole of gear box casing 11, being inserted into the planetary wheel 4, by bearing seat 14 and bolt be contained in the mounting hole of gear box casing 11.
