The specific embodiment
Shown in Fig. 2-8, the utility model is the Power Drive Unit of a kind of escalator or moving sidewalk, comprises driving main shaft 1 and driving host etc.Being installed in has step driving chain sprocket and a handrail driving chain wheel 20 on the driving main shaft.Driving host comprises drive motor 24, deceleration system and brake system 25 three parts.Driving host is installed on the staircase and girder 2 through main frame mounting seat 29, and the driving main shaft other end is installed on the staircase and girder 2 through spindle bearing holder 21.Perhaps, the driving main shaft two ends are connected with two driving host respectively, form the two-shipper drive configuration.
Deceleration system in the driving host comprises bonded assembly input shaft, planetary gear speed reducing mechanism 4, taper direction reverser 3 and output shaft successively.Planetary gear speed reducing mechanism 4 will change into the slow speed of revolution that needs from the high rotating speed that drives motor 24.Taper direction reverser 3 mainly acts on except playing certain deceleration; The more important thing is and let deceleration system output shaft and input shaft be 90 degree angles; Thereby realize that driving main shaft 1 is connected with the output shaft of deceleration system is coaxial; And be 90 degree with the machine shaft 14 of drive motor 24, and it is little that complete machine is taken up an area of, and structure is more compact.The output shaft of deceleration system and the connection mode of driving main shaft: the face face cooperates between the output shaft end face of flange of spindle flange face and deceleration system, and two flange faces are connected by high strength tie bolt 19.
The input shaft of deceleration system is connected with the machine shaft 14 of drive motor 24 through coupler 6.Preferably, coupler is an elastic coupling.This connection mode not only can automatic compensation motor and deceleration system assembly error, and motor can be separated with deceleration system fully, is convenient to separately motor or deceleration system safeguarded.
Drive motor 24 also comprises rotor 7 and coil 8, and its rotor 7 is located at coil 8 peripheries.Adopt outer-rotor structure, can make the diameter maximization of rotor, thereby be implemented in the maximization that realizes the rotor inertia of motor under the limited situation of overall dimension.The increase of rotor inertia means the expansion of the product scope that this main frame is suitable for.Drive motor 24 can be selected from asynchronous dynamo or synchronous dynamo.
Machine shaft 14 ends are provided with coder 12, and after this coder 12 was fixedly installed in machine shaft 14 ends through coder installation shaft 11, the outside was covered with coder seat 13 again.Since coder installation shaft 11 and machine shaft 14 both for dividing body structure, it is removable therefore connecting, thereby is convenient for changing the coder of different model.
Rotor 7 rear ends are installed with jiggering ring gear 9.When needing manual jiggering, hand turning gear 23 is installed on the electric machine stand barring hole, the jiggering driving gear on the hand turning gear 23 meshes with above-mentioned jiggering ring gear 9, realizes manual jiggering.Because the handwheel diameter of hand turning gear 23 is greater than jiggering driving gear diameter, according to the size of power and the arm of force length principle that is inversely proportional to, the power on the handwheel of acting on is less than the power on the jiggering gear, thereby reaches the laborsaving purpose of jiggering.
Brake system comprises: with rotor 7 incorporate brake wheels 15 (being rotor 7 leading portion parts), be enclosed in the compression spring 26 of peripheral brake collar 16 of brake wheel 15 and control brake tensile force of belt size, as the braking motor 27 in drg operation power source etc.Glancing impact, braking motor 27 loosens, and the elastic force of compression spring 26 compresses brake collar 16 and brake wheel 15, and the friction force that produces between it is with the driving host stop.Because brake wheel 15 is integrated with rotor 7, be equivalent to braking force and directly brake on rotor 7, the braking reliability is high.
Embodiment 1
Present embodiment is shown in Fig. 2-7.Driving host comprises drive motor 24, deceleration system and brake system 25 three parts.The main frame installation base plate 28 of driving host 24 is fixed through adjusting bolt 30, bolt of rear end plate 31, adjusting bolt 32 with main frame mounting seat 29, and through regulating above-mentioned bolt, driving host 24 can three directions of x-y-z be adjusted in the space.
Drive motor 24 is a permagnetic synchronous motor, comprises bearing seat 5, rotor 7, motor coil 8, jiggering ring gear 9, electric machine stand 10, coder shaft 11, coder 12, coder seat 13, machine shaft 14, hand turning gear 23.Machine shaft 14 is installed in respectively on electric machine stand 10 and the bearing seat 5 through front and back bearings.Coder shaft 9 is passed through screw retention at machine shaft 14 ends.Jiggering ring gear 9 is connected rotor 7 ends through screw, can carry out jiggering through hand turning gear 23.
Drive motor 24 is realized coaxial the connection through coupler 6 with the input shaft of deceleration system, docks with the seam of deceleration system through the flange on the bearing seat 5 and locatees, and the dependence tie bolt is fastening, thereby is connected as a single entity.The coaxial connection of one end of the output shaft of deceleration system and driving main shaft 1.The other end of driving main shaft 1 is installed on the bearing seat mounting base 34 through spindle bearing holder 21.Spindle bearing holder 21 can through regulate position between bolt 33,35,36 and the bearing seat mounting base 34 in the space three directions of x-y-z all can adjust, thereby improve setting accuracy, the stability of increase machine run.
Embodiment 2
When the hoisting depth of escalator or moving sidewalk is big to a certain degree, when a main engine power is not enough, can adopt as shown in Figure 8.Symmetrical structure is made at driving main shaft among the embodiment 11 two ends.Bearing seat mounting base 34 replaces with another main frame mounting seat 29, and another driving host is installed, and forms the two-shipper drive configuration.
