Abstract

PURPOSE:To prevent the braking of a rotor from being reduced, by pressing the rotor against a stationary section with air pressure and by contriving the rotor not to slide in the axial direction, after the braking of the rotor of a gap motor in the axial direction is performed by the energizing force of a brake spring. CONSTITUTION:On the cylinder surface formed in a frame 1, a damping plate 8 is fitted not to be rotatably moved, and an air chamber 10 is formed between the damping plate 8 and the frame 1. On braking, a rotor 7 is pressed against the damping plate 8 via a brake lining 11 by the energizing force of a brake spring 12 to perform braking. After that, air is injected into the air chamber 10 through a vent hole 13, and by the air pressure and by the damping plate 8, via the brake lining 11, the rotor 7 is pressed to a collar 15 which is a stationary section in the axial direction, and the rotor is contrived not to be moved in the axial direction. Accordingly, a braking force is increased, and the braking of the rotor is prevented from being reduced.

(Prior art and problems) A brake motor performs braking by pressing a brake lining fixed to the motor rotor against a braking surface provided on a frame such as a bracket by the axial movement of the rotor. Yes, the AG brake motor has a larger braking part diameter, so the brake torque is 250% compared to a general brake motor that has a built-in brake device in a radial gap type motor (brake torque is 150%). Because it is large and has a flat outer shape, it is often used for adjusting the slide of the ram of press equipment.

However, the vibrations in press equipment are intense, and the vibrations cause the rotor to momentarily move in the axial direction against the biasing force of the brake spring, separating from the braking surface of the fixed part, and as a result, the braking of the brake motor's rotor loosens. , there is a problem that the positioned ram may shift.

The rotor 7 is slidably fitted in the axial direction of the rotary shaft 3, and the rotation of the rotor 7 causes the rotary shaft 3 to rotate. A cylinder surface is formed inside the opposite-load side of the machine frame (frame 1), and a brake plate 8 is fitted onto this cylinder surface in an airtight manner. This brake plate 8 is prevented from rotating relative to the cylinder surface by a torque bin 9, and is slid in the axial direction of the rotor 7 as shown by arrow a by air pressure in an air chamber 10, which will be described later. . Further, a brake lining 11 is provided on the end surface of the rotor 7.
(a brake lining may be attached to the end face of the brake plate 8), and by pressing the brake lining 11 against the brake plate 8, the rotation of the rotor is stopped. For this reason, a brake spring 12 such as a compression spring that slides the rotor 7 in the axial direction indicated by the arrow and presses the brake plate 8 in the direction of the brake plate 8 is disposed within the machine frame. Furthermore, an air chamber 10 is formed on the left side of the brake plate 8 between it and the machine frame (frame 1), and an air supply/discharge port 13 is connected to this air chamber 10 to supply air into the air chamber 10. It is designed to supply air and discharge the supplied air. Further, a thrust bearing 14 is interposed between the right end portion of the brake spring 12 and the machine frame (bracket 2), and a collar 15 is fitted onto the rotating shaft 3. Note that the stator 6 is energized by a power supply cable 16 led out from the machine frame.

First, air in the air chamber 10 is discharged through the air supply/discharge port 13 . As a result, the rotor 7 slides to the left due to the biasing force of the brake spring 12, and the brake lining 11
The brake plate 8 also slides to the left through the rotation of the rotor 7, resulting in the state shown in the figure. When the stator 6 is energized in this state, a magnetic attraction force is generated and the brake spring 12 is energized.
The rotor 7 slides to the right against this, and the braking of the rotor 7 is released. As a result, the rotor 7 and the rotating shaft 3 rotate integrally, and the rotation of the rotating shaft 3 allows sliding adjustment of a ram (not shown) of the press device. Once the ram is in place, the current is turned off and the magnetic attraction disappears. Therefore, the rotor 7 is pressed against the brake plate 8 via the brake lining 11 by the biasing force of the brake spring 12, and the rotor 7 is braked. Next, after this braking, air pressurized to 3 to 5 atmospheres is injected from the air supply/discharge port, and this air pressure causes the brake plate 8 to move the rotor 7 through the brake lining 11 to the fixed part in the axial direction (rotation is stopped). The braking force of the rotor 7 is strengthened in a state in which the rotor 7 is pressed against the collar 15, which is freely movable, and is prevented from moving in the axial direction. The brake torque generated by this air locking mechanism is 2500% or more, and the rotor is strongly braked. Therefore, the rotor 7 is maintained in a braking state without loosening due to vibrations, etc., so that the ram does not shift during pressing operations by the press device.
