Next with reference to Fig. 3, the control system according to the actuating device of realizing mode of the present invention is described below.This control system has control part 41, and control part 41 is connected respectively on the coder 16 and brake equipment 30 of electric notor device 10, electric notor device 10.Actuating device drives the motion elevator crib of elevator, by means of the excitation of the electromagnet of the coil 12 of control part 41 control electric notor devices 10 and brake equipment 30, controls above-mentioned motion elevator crib by preset program simultaneously.In addition, control electric notor device 10 and brake equipment 30 according to information from the revolution of the relevant electric notor device 10 of coder 16 output.
To the control that drive the motion elevator crib of elevator by the actuating device shown in Fig. 1-3 be described.At first, when electric notor device 10 is started by the signal from control part 41 and rotor 14 when being rotated, input shaft 21 is rotated subsequently, and a plurality of friction rotating elements 23 that contact with the circumferential surface of input shaft 21 respectively transmit by friction and rotate around tween drive shaft 24.Then, a plurality of friction rotating elements 23 transmit by friction with its inner cylindrical elements 25 that contacts and rotate, and simultaneously, the belt pulley 27 that joins on the cylindrical elements 25 by a plurality of pins 26 rotates with its inner circumferential portion 27a.Then, the cable wire 29 around belt pulley 27 in the groove 28 on being formed on external peripheral surface is driven and perpendicular movement, so the motion elevator crib of elevator can perpendicular movement.What it should be noted that is that the rotation of input shaft 21 adopts a predetermined reduction ratio that transmits to be decelerated, so belt pulley 27 can be with a certain rotative speed rotation.
On the other hand, for the motion elevator crib that makes elevator stops, therefore, electric notor device 10 is stopped by the signal from control part 41, and in this generation, brake equipment 30 is started.By the operation of brake equipment 30, the direction pushing brake pad 33 shown in the arrow t of brake body 34 in Fig. 1 stops the rotation brake disc 31 so that affact on the both sides of brake disc 31, thereby the belt pulley 27 with brake disc 31 rotations is stopped.Then, cable wire stops their motion, so the motion elevator crib of elevator has stopped.
In service at the brake equipment 30 that constitutes as mentioned above, because brake disc 31 is arranged to extend along the radially R of belt pulley 27, therefore the radius at the position of brake pad 33 brake disc 31 becomes big, adopting this brake disc to obtain under a certain size the situation of brake torque, it is little to need to be applied to the braking force that the braking-force ratio on the brake disc need be applied on the brake disc that is not brake disc of the present invention from brake body 34 by brake pad 33.Therefore, the braking potential of brake body 34 can be less, and this helps to make whole brake equipment 30 miniaturizations.
In addition, in change gear transmission device 20, a plurality of friction rotating elements 23 are around the circumferential surface setting of input shaft 21, cylindrical elements 25 is holding these friction rotating elements 23, therefore the rotating element 23 that rubs produces inner the contact with the inner circumferential surface of cylindrical elements 25, belt pulley 27 is arranged on the outer circumferential sides of cylindrical elements 25, therefore belt pulley 27 is with cylindrical elements 25 rotations, in a word, change gear transmission device 20 is configured to the radially R extension of edge perpendicular to the belt pulley 27 of input shaft 21.Therefore, according to this structure, change gear transmission device 20 along axially can making of input shaft 21 for example the existing actuating device than shown in Figure 4 is thinner.And, because brake equipment 30 is positioned at the radial outside of belt pulley 27, promptly be positioned on the radially R of belt pulley 27, therefore the actuating device integral body of elevator can be made thinner, therefore can make the actuating device miniaturization, thereby make the elevator cabin in the building that is used for being provided with elevator less, and can save the space in the building better.
And, because brake equipment 30 is positioned at the radial outside (radially R) of belt pulley 27, when keeping direction along input shaft 21 thin, can be provided with a plurality of or two brake equipments for example.With regard to two brake equipments were set, the ability of each brake equipment can be half of ability that a brake equipment is set, thereby makes the further miniaturization of brake equipment.In addition, one in two brake equipments can be used as the conventional brake device, and another can be used as emergency braking apparatus simultaneously.In this case, for example, if each part in the change gear transmission device is worn, the rotation of input shaft 21 can not normally be delivered to belt pulley, the detection of this abnormal state can be started emergency braking apparatus, thereby the motion elevator crib of elevator is stopped.
Therefore, realize mode of the present invention although described, the present invention is not limited to these, can carry out various changes to the present invention under the situation that does not break away from know-why of the present invention.For example, cylindrical elements and belt pulley can form one, and cable wire can be on the external peripheral surface of cylindrical elements.Two or more brake equipment certainly is set in addition.
According to the actuating device of elevator of the present invention, not only can make the brake equipment miniaturization, but also can make the actuating device integral body must be thinner than existing along the input shaft directional structure vectorical structure.
