Abstract
The utility model relates to a mute enclosed power-off brake. The mute enclosed power-off brake is formed by a single magnetic yoke, double armatures and a single coil or a plurality of coils. The single coil or the plurality of coils is or are allocated to two power supplies uniformly, the brake effect can be achieved as long as one of the power supplies is switched on, the double-brake effect can be achieved if the other power supply is switched on, and accordingly the reliability and the safety of braking are improved. A release handle and an auxiliary release bolt are arranged in the same brake simultaneously. The double-manual-release function is achieved through the brake. A buffer gasket and an adjusting nut are added to the bilateral sides of a buffering cushion respectively so as to achieve the maximum mute effect. Accordingly, the mute enclosed power-off brake has the advantages of being easy to install, small in working size, good in mute effect, high in safety and reliability and the like.
Description
Technical field
The utility model relates to electromagnetic brake field, especially a kind of quiet closed power-off brake.
Background technique
Power-off brake is to utilize spring and the power supply mechanical device that brake disc is braked and discharged as power source, and it carries out braking under powering-off state, therefore claim power-off brake.Its structure comprises yoke, armature, spring, coil, friction disk, friction plate, release lever composition.The working principle of power-off brake is: yoke forms electromagnet with the coil being loaded in yoke, in the time of coil access failure power supply, spring is pressed in armature on friction plate, forms surface friction drag on friction plate, thereby friction disk is braked, and the equipment that makes to be connected on friction disk is braked; In the time of coil electricity, the magnetic force that yoke produces is contrary with the thrust that spring produces, the electromagnetic force that is greater than spring thrust attracts yoke on one side in armature, make to separate between armature and friction plate, the surface friction drag that has just produced gap like this between armature and friction plate and make to act on friction plate disappears, and braking is disengaged.In use, due to poor working environment, it is poor to protect for power-off brake in the past, and easily water inlet, oil, make the larger decline of break braking torque, easily enters foreign matter and block, and braking function and release function were lost efficacy; In the time that break needs manual release, often, because of manual release disabler and without release function for subsequent use, make troubles to work; At work, noise is large for break, although be provided with buffering spacer, the thickness of buffering spacer is difficult to join rationally suitably, thick, or thin, thick easy generation current sound, with thin, be difficult to abate the noise, quiet require high place be not suitable for application; Break is designed to a yoke and drives an armature, takes up room large, could not on the break of single yoke, realize two braking functions.
Summary of the invention
The purpose of this utility model is that the existing power-off brake noise of change is large, the problems such as protection difference and manual release are unreliable, change the unparalleled braking function of single yoke break in the past, design be a kind ofly easy to install, quiet, reliable operation, quiet closed power-off brake that volume is little, the technical solution of the utility model is so to realize:
Quiet closed power-off brake; comprise yoke, armature, friction disk, friction plate, construction bolt, buffering protective cushion, release lever, dust ring, switch, be located at spring and coil in yoke; armature is divided into symmetrical two; all be slidably connected by lead guide pillar and bolt and yoke; between buffering protective cushion and yoke, be provided with buffering spacer; buffering protective cushion opposite side is provided with adjusting nut, and release lever below is provided with through yoke and is connected in the auxiliary release bolt on armature.
As preferably, in described adjusting nut, be provided with contour cover, construction bolt successively through yoke, buffering spacer, buffering protective cushion, contour cover and armature be braked body and be connected.Regulating adjusting nut in appropriate location, can make the crush of buffering spacer in optimized buffer state, make the collision of armature and yoke reach the gentliest or not bump, can be almost zero by noise control, reaches quiet effect.
As preferably, dust ring is wrapped in break surrounding gap and break and is braked the gap between body.Can anti-sealing, the foreign matter such as oil, dust enters in break, effectively prevents from getting rusty, skidding, and prevents that foreign matter is stuck by armature, reduced the probability of happening of brake troubles, improved the reliability of break work.
As preferably, release lever end is provided with criss-crossing V-type groove, between release lever and yoke, is provided with steel ball, and described steel ball is located between V-type groove and the hole at the yoke back side.
As preferably, the number of described coil is more than 1.
As preferably, described yoke is rectangle, and endoporus is circular, and mounting hole is located on four jiaos of yoke or periphery.Yoke is set to square-outside and round-inside, and interior circular hole can directly be installed client's part coding device, has saved encoder mounting rack; Mounting hole is located on foreign side's periphery of yoke, and therefore the braking radius of friction disk can maximize the use, and has increased accordingly break moment of torsion, makes break miniaturization, has saved material.
The quiet closed power-off brake of the utility model design, adopt the structure of single yoke, double armature, single or multiple coils, all coils is averagely allocated to two power supplys, as long as power supply of connection just can reach the effect of braking, connect again the effect that another power supply just reaches two brakings, improved reliability and the Security of braking; Release lever is arranged in a break with the auxiliary bolt that discharges simultaneously, and break has dual manual release function.
Yoke and armature are slidably connected with guiding guide pillar, make break in adhesive or releasing course, and the fast moving of armature becomes steadily, are difficult for tilting, and make the dotted line collision of armature and yoke or friction plate become plane collision, have lowered noise; In braking process, braking force reaches armature by friction plate, reach guiding guide pillar, yoke and construction bolt by armature again, avoid braking force to reach yoke and construction bolt by contour cover, fixing so contour cover and repeatedly can be set to large Spielpassung between motion armature, both do not contact, and have avoided the generation of noise.
The beneficial effects of the utility model are:
The crush that 1, can regulate easily buffering spacer, makes it to bring into play optimized buffer effect, makes break work in mute state.
2, in the situation that same nominal braking torque is provided, break can do littlely, is conducive to save material, reduces costs.
3, improve the protection of break, and realized two brakings on single yoke break, improved the reliability of break.
