Description
Technical field
The utility model belongs to the escalator technical field, relates in particular to a kind of actuating device of escalator.
Background technology
Existing driving device of escalator comprises motor, drop-gear box, main drive shaft, drive sprocket, first driven sprocket and second driven sprocket, and drive sprocket, first driven sprocket and second driven sprocket all are connected on the main drive shaft.Motor and drop-gear box are given drive sprocket by chain with transmission of power, and drive sprocket drives main drive shaft and rotates, and drive two driven sprockets thus and rotate, and driven sprocket then drives component movement such as step by chain.Give drive sprocket by motor, drop-gear box and chain with transmission of power in the above-mentioned driving device of escalator, its power transmission process is not steady, easily produces vibration and noise.Simultaneously, because messenger chain is longer, work efficiency is low, and waste of power is big, and fault rate is higher, and the life-span is short, and maintenance cost is higher.
The utility model content
It is steady that technical problem to be solved in the utility model provides a kind of transmission of power, high efficiency, and fault rate is low, the driving device of escalator of long service life.
The utility model comprises stator axis, rotor sleeve, first sprocket wheel, second sprocket wheel, clutch shaft bearing and second bearing; Outside face in described stator axis is arranged coil, and the inside face of rotor sleeve is arranged permanent magnet, and described rotor sleeve is enclosed within outside the stator axis; One end of stator axis interconnects by the clutch shaft bearing and first sprocket wheel, and the other end interconnects by second bearing and second sprocket wheel; One end of rotor sleeve is captiveed joint with first sprocket wheel, and the other end is captiveed joint with second sprocket wheel.
In the utility model behind the coil electricity of driving device of escalator, the magnetic field interaction that magnetic field that coil produces and permanent magnet produce produces propulsive effort, the driving rotor sleeve rotates, thereby drive first sprocket wheel and second sprocket rotation, first sprocket wheel and second sprocket wheel then drive component movement such as step by chain.Actuating device in the utility model has changed in the existing driving device of escalator and to adopt motor and drop-gear box to give drive sprocket by chain with transmission of power, drive the type of drive of two sprocket rotation again by main drive shaft by drive sprocket, but utilize original main drive shaft as stator axis, make rotor sleeve rotate by means of coil and permanent magnet, by two sprocket rotation of rotor sleeve direct drive, owing to saved chain gear, so transmission of power is steady, high efficiency, fault rate is low, also corresponding raising in service life.
Preferably, interconnect by the bolt and nut fastener between the described rotor sleeve and first sprocket wheel and second sprocket wheel.
Preferably, described permanent magnet is a Nd-Fe-B permanent magnet.
Figure of description
Fig. 1 is the structural representation of driving device of escalator.
The specific embodiment
As shown in Figure 1, the driving device of escalator in the present embodiment comprises stator axis 1, rotor sleeve 2, first sprocket wheel 3, second sprocket wheel 4, clutch shaft bearing 5 and second bearing 6.Outside face in described stator axis 1 is arranged coil 1-1, and the inside face of rotor sleeve 2 is arranged permanent magnet 2-1, and described rotor sleeve 2 is enclosed within outside the stator axis 1.One end of stator axis 1 interconnects by the clutch shaft bearing 5 and first sprocket wheel 3, and the other end of stator axis 1 interconnects by second bearing 6 and second sprocket wheel 4.Captive joint between one end of rotor sleeve 2 and first sprocket wheel 3, captive joint between the other end of rotor sleeve 2 and second sprocket wheel 4.Preferably, interconnect by the bolt and nut fastener between the rotor sleeve 2 and first sprocket wheel 3 and second sprocket wheel 4; Permanent magnet 2-1 is a Nd-Fe-B permanent magnet.
The magnetic field interaction that magnetic field that coil 1-1 energising back produces and permanent magnet 2-1 produce produces propulsive effort, driving rotor sleeve 2 rotates, driving first sprocket wheel 3 and second sprocket wheel 4 rotates, 4 on first sprocket wheel 3 and second sprocket wheel drive component movement such as step by chain.
