Abstract
The utility model relates to a damping power-off brake which comprises a magnet yoke, a coil, an armature and a friction plate. The coil is poured in the magnet yoke through epoxy resin, the armature is arranged at the opening end of the coil, a damping plate is fixedly connected onto the other end surface of the armature through a press plate and contacts a core board, the core board is connected with a connection baffle through a rivet, and the friction plate is adhered to the other end surface of the core board through epoxy resin and contacts a braking disc. The damping power-off brake has a braking effect permanently during power off and power on, has a large braking torque after power off and a small braking torque after power on, and can adjust the air gap when abrasion affects performance parameters by aid of an additionally arranged torque adjustment device.
Description
Technical field
The utility model belongs to the power-off brake technical field, particularly a kind of damping power-off brake that can be applicable to medical machinery and accurate mapper.
Background technique
In X-ray machine, CT machine, nuclear magnetic resonance and large-scale surveying instrument, extensively adopt power-off brake at present.Because it has reliable accurately location characteristics, add simple to operately, easy to maintenance, begun a large amount of selecting for use.This common power-off brake adopts friction disc brake, utilizes spring pressure to produce frictional force on the surface of two contacts, reaches the purpose of friction catch.This break often causes the handle displacement dislocation to occur because extraneous false touch is moving in operation process; Again it, its braking moment is constant nonadjustable, after braking moment disappeared, all moments disappeared, and have influenced the precision in mapping and the medical procedure; When the operation of friction plate through the long period, some wearing and tearing are arranged in the process of slippage certainly, its moment parameter changes, and has strengthened and has opened distance, because the loss of friction plate strengthens running clearance, makes it influence period of braking, directly has influence on the performance parameter of product.Because the pressure of common power-off brake stage clip is placed among the yoke, can not regulate simultaneously, revise after must dismantling, make troubles also for the maintenance of equipment.
Summary of the invention
The utility model can be adjusted moment (between certain limit) size for the technical problem that exists in the solution known technology provides a kind of, also can adjust the damping power-off brake of air gap.
The technological scheme that the utility model is taked for the technical problem that exists in the solution known technology is:
A kind of damping power-off brake, comprise yoke, coil, armature and friction plate, described coil by poured with epoxy resin in yoke, described armature is arranged at the opening end of coil, be fixedly connected with damping fin by pressing plate on another end face of described armature, described damping fin contacts with central layer, and described central layer connects by rivet and connects block, the other end of described central layer adhering with epoxy resin friction plate, described friction plate contacts with brake disc.
Described brake disc is fixed on the yoke by regulating bolt, and is provided with adjusting nut at the head of regulating bolt.
Vertical riveted joint has the bar of deciding on the end face of described armature, describedly decides bar and passes through hole on the brake disc, and the dish spring is placed in order to be decided on the bar, describedly decides boom end and is connected with nut.
Advantage and the good effect that the utlity model has are:
1. damping fin adopts plasticity, high temperature resistant, abrasion material low, stable performance to make, and after braking moment disappears, still can also keep certain damping torque, thereby guarantee trueness error in mapping and medical procedure.
2. adjust the working clearance, lock through adjusting nut, regulate by adjusting nut, both made things convenient for the stability that can also guarantee moment, armature can also lead by regulating bolt simultaneously.
3. because the dish spring is positioned over the outside of yoke, specifically be positioned at the outside of brake disc, therefore can directly adjust at the scene, can reach technical requirements by adjusting nut, convenient for maintaining has been saved the time.
Description of drawings
Fig. 1 is the utility model structure sectional view.
Among Fig. 1,1. central layer, 2. damping fin, 3. yoke, 4. coil, 5. armature is 6. regulated bolt, and 7. adjusting nut 8. decide bar, 9. nut, 10. dish spring, 11. connection blocks, 12. friction plates, 13. brake discs.
Embodiment
For further understanding content of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
See also Fig. 1, a kind of damping power-off brake, include yoke 3, coil 4, armature 5, damping fin 2 and friction plate 12, coil 4 by poured with epoxy resin in yoke 3, armature 5 is arranged at the opening end of coil 4, damping fin 2 usefulness pressing plates are fixed on another end face of armature 5, and damping fin 2 contacts with central layer 1.Damping fin 2 adopts plasticity, high temperature resistant, abrasion material low, stable performance to make, and after braking moment disappears, still can also keep certain damping torque, thereby guarantee trueness error in mapping and medical procedure.Central layer 1 connects connection block 11 by rivet is fixed on the central layer 1 it, the other end of central layer 1 adhering with epoxy resin friction plate 12, and friction plate 12 contacts with brake disc 13.Brake disc 13 is fixed on the yoke 3 by regulating bolt 6, and is provided with adjusting nut 7 at the head of regulating bolt 6, adjusts the working clearance, locks through adjusting nut 7 again, regulates by adjusting nut 7, both the convenient stability that can also guarantee moment.Armature 5 can also lead by regulating bolt 6 simultaneously.Vertical riveted joint has the bar of deciding 8 on the end face of armature 5, decides bar 8 and passes through hole on the brake disc 13, and dish spring 10 is placed in order to be decided on the bar 8, decides bar 8 ends and is connected with nut 9, is screwed to required positive pressure value by nut 9.Because dish spring 10 is positioned over the outside of yoke 3, specifically be positioned at the outside of brake disc 13, therefore can directly adjust at the scene, can reach technical requirements by adjusting nut 9, convenient for maintaining has been saved the time.
Working principle of the present utility model is, when coil is connected DC electrical source, produces magnetic pull armature is drawn onto the yoke end face, and this moment, big braking moment disappeared, and the less braking moment of job requirement still exists, and it can require set according to product performance.After the outage, armature is pressed to friction plate on the brake disc by the reaction force of dish spring fast, reaches accurate braking.
The permanent strap brake effect during with energising of the utility model when outage, braking moment is bigger after the dead electricity, energising back braking moment less (because operating conditions needs), and increased moment regulating device and friction disc wear air gap when influencing performance parameter and also can adjust.
The above only is the preferable example of executing of the present utility model, is not to limit practical range of the present utility model.Be that all equivalences of doing according to the content of the utility model claim change and modification, all fall into technical scope of the present utility model.
