Abstract
The utility model relates to a disk rotor braking device for braking motor in the field of disk motor parts. A rotor of the device is in the shape of a circular disk, an annular friction plate is pasted to the back surface of the rotor, and the rotor and the friction plate are combined into a whole through sunk screws. A compression spring is installed in a central slot of the iron core of the rotor, a casing is fixed on a motor cabinet and covers the rotor, and a brake gap is reserved between the casing and the annular friction plate. The braking device with the function of normal rapid running with power on and instant braking with power off has novel structure, small volume, short axial size, braking flexibility and positioning accuracy. The friction plate can brake for one hundred thousand times without adjustment. Therefore, the utility model is a novel product for replacing traditional electromagnetic brake asynchronous motors, and is used for various mechanical master drivers, auxiliary drivers, construction swinging scaffolds, forging and pressing machine tools, and other industries.
Description
Technical field
The utility model belongs to the disc type electric machine components range, particularly is used for a kind of disc type brake rotor brake apparatus of industries such as various mechanical main transmissions, accessory drives, building hanging basket, forging machine tool.
Background technology
Traditional electrical magnetic brake asynchronous motor is an additional direct current electromagnetic brake between the rear end cap of motor and fan, and brake is made up of yoke, magnet exciting coil, spring, brake disc, armature component, spline housing, hand release and construction bolt etc. respectively.The moving releasing device operation of armrest, when coil electricity, coil produces magnetic field inhales to yoke armature, and armature and brake disc are held; When coil blackout, magnetic field disappears, and armature and brake disc break away from, and armature is released.Spring applies pressure to armature component, the friction plate on the brake disc is compressed, thereby produce the purpose that braking moment reaches braking.But the moving operation of armrest releasing device vary with each individual, and human factor is many, and safety will be affected.
Summary of the invention
The purpose of this utility model is to be the moving operation of armrest releasing device at traditional electrical magnetic brake asynchronous motor, vary with each individual, and human factor is many, the affected deficiency of safety, and provide a kind of disc type brake rotor brake apparatus, it is characterized in that, rotor is disc, be bonded with the annular friction sheet at the rotor back side, and they are formed one with sunk screw, the compression spring be contained in the central channel unshakable in one's determination of rotor, casing is fixed on the motor cabinet, cover rotor and and the annular friction sheet between keep braking gap.
The disk end face unshakable in one's determination of described rotor has radial groove to embed the aluminium sliver.
Described annular friction sheet is an asbestos-free friction sheet.
The beneficial effects of the utility model are rotor and brake gear composition one, novel structure, and volume is little, the axial dimension weak point, braking is flexible, accurate positioning, having switches on normally moves rapidly, instantaneous the stopping of cutting off the power supply stopped fast function, and friction disc brake need not adjustment for 100,000 times.It is the novel product that substitutes traditional electrical magnetic brake asynchronous motor.
Description of drawings
Fig. 1 is the generalized section of disc type brake rotor brake apparatus.
Embodiment
The utility model provides a kind of disc type brake rotor brake apparatus.Below in conjunction with accompanying drawing the utility model is illustrated.
Figure 1 shows that the generalized section of disc type brake rotor brake apparatus.
Rotor 6 is disc, being coated with one deck seccotine equably at the disk end face unshakable in one's determination of rotor 6, to carry out adhesives be asbestos-free annular friction sheet 5 (WSI56 asbestos-free friction sheet), and they are formed one with sunk screw 2, compression spring 1 is contained in the central channel unshakable in one's determination of rotor 6, casing 4 is fixed on the motor cabinet 7, cover rotor 6, and and annular friction sheet 5 between keep braking gap 3.Disk end face unshakable in one's determination at rotor has radial groove to embed the aluminium sliver, forms the aluminium mouse-cage type.After energising, except that generation makes the round rotor turning moment, also produce axial displacement simultaneously, make the compression length of spring compressed and unclamp annular friction plate 5, remove and brake; Motor normally moves, when cutting off the power supply, epitrochanterian annular friction sheet 5 is under the effect of compression spring 1, rotor annular friction plate 5 contacts with casing 4, need not increase power consumption newly, the generation braking moment shuts down motor rapidly naturally.Reach the braking purpose.This novel structure, rotor is formed one, Braking mode rotor with the annular friction sheet of doing brake, volume is little, has energising and normally moves the instantaneous function of stopping and stopping of cutting off the power supply, friction disc brake need not for 100,000 times to adjust, and is the desirable corollary equipment that the required driving of mechanical industry is stopped and stopped.
Specification digest
The utility model belongs to a kind of disc type brake rotor brake apparatus of disc type electric machine components range.This device rotor is disc, be bonded with the annular friction sheet at the rotor back side, and with sunk screw they formed one, the compression spring is contained in the central channel unshakable in one's determination of rotor, casing is fixed on the motor cabinet, cover rotor and and the annular friction sheet between keep braking gap.The utility model novel structure, volume is little, axial dimension is short, and braking is flexible, accurate positioning, the brake noiseless, no energy consumption, pollution-free, having switches on normally moves rapidly, instantaneous the stopping of outage stopped fast function, friction disc brake need not for 100,000 times to adjust, and is the novel product that substitutes traditional electrical magnetic brake asynchronous motor; Belong to the environment-friendly type brake gear, be used for industries such as various mechanical main transmissions, accessory drives, building hanging basket, forging machine tool.
