Description
[technical field]
The utility model relates to a kind of technical field of electricity loss brake, especially a kind of skill of electricity loss brake magnetic yoke
Art field.
[background technique]
Electricity loss brake is the mechanical dress braked and discharged to brake disc using spring and power supply as power source
It sets, is to execute braking under power blackout situation, therefore claim electricity loss brake.Its structure includes magnetic yoke, armature, spring, coil, rubs
Wipe the composition such as disk, friction plate, release lever, microswitch.The working principle of electricity loss brake are as follows: magnetic yoke with loaded in magnetic yoke
Coil forms electromagnet, and in coil access failure power supply, armature is pressed on friction plate by spring, and friction is formed on friction plate
Resistance is braked the equipment being connected on frictional disk so that frictional disk be made to be braked；When the coil is energized, magnetic yoke generates
Thrust that magnetic force and spring generate makes armature and rubs on the contrary, armature is attracted to magnetic yoke on one side by the electromagnetic force for being greater than spring thrust
It is separated between pad, just produces gap in this way between armature and friction plate and to act on the frictional resistance on friction plate
It disappears, braking is released from.In the prior art, armature and magnetic yoke are reduced by the way that cushion is fixedly installed on the working face of magnetic yoke
Collide the noise generated, since the working face of magnetic yoke is stretched out in cushion working end, after being squeezed, the circumferential surface of cushion extension end without
Support causes the deformation of cushion working end serious, the phenomenon that armature and magnetic yoke clamping cushion occurs, cushion is caused to damage,
Make the service life reduction of cushion.
[utility model content]
The purpose of this utility model is exactly to solve the problems of the prior art, proposes a kind of power loss for improving buffering pad life
Brake magnetic yoke.
To achieve the above object, the utility model proposes a kind of electricity loss brake magnetic yoke, including it is magnetic yoke main body, several
Groove and several buffer gears, the working face of the magnetic yoke main body are equipped with equally distributed groove, are equipped in the groove
Buffer gear, the buffer gear include that cross section is circular cyclic annular cushion and the intermediate buffering in cyclic annular cushion
Pad.
Preferably, the magnetic yoke main body is equipped with several threaded holes, one end of each threaded hole is connected to a groove, separately
The rear end of magnetic yoke main body is run through in one end, is equipped with adjusting screw rod in the threaded hole, the front end of the adjusting screw rod, which is equipped with, stretches
Enter the support base in groove, the front end of the support base is equipped with inserting groove, and the inserting groove is interior inserted with intermediate buffering pad.
Preferably, the internal diameter of the threaded hole is not less than the diameter of groove.
Preferably, the diameter of the intermediate buffering pad is slightly larger than the diameter of inserting groove, the internal diameter of the ring-type cushion
The slightly smaller than diameter of intermediate buffering pad.
Preferably, the rear end of the ring-type cushion contradicts on support base.
The utility model has the beneficial effects that the utility model is equally distributed by the way that the working face of magnetic yoke main body to be equipped with
Groove, is equipped with buffer gear in groove, and buffer gear includes that cross section is circular cyclic annular cushion and is located at cyclic annular buffering
Intermediate buffering pad in pad avoids the occurrence of the clamped drawback of conventional buffer pad；It is equipped with adjusting screw rod in threaded hole, adjusts spiral shell
The front end of bar is equipped with the support base protruded into groove, and the front end of support base is equipped with inserting groove, and inserting groove is interior inserted with centre
The overhang that buffer gear stretches out groove is adjusted in cushion, and guarantee reaches best noise reduction effect, and dismantles adjusting screw rod
Afterwards, buffer gear is pulled out together with adjusting screw rod, facilitates the replacement of cushion；Compared with prior art, it can be improved buffering
Pad life facilitates the replacement of cushion and the adjusting of overhang.
The feature and advantage of the utility model will be described in detail by embodiment combination attached drawing.
[Detailed description of the invention]
Fig. 1 is a kind of structural schematic diagram of electricity loss brake magnetic yoke of the utility model.
In figure: 1- magnetic yoke main body, 2- groove, 3- buffer gear, 4- threaded hole, 5- adjusting screw rod, 6- support base, 7- grafting
Slot, 31- ring-type cushion, 32- intermediate buffering pad.
[specific embodiment]
Refering to fig. 1, a kind of electricity loss brake magnetic yoke of the utility model, including magnetic yoke main body 1, several grooves 2 and several
Buffer gear 3, the working face of the magnetic yoke main body 1 are equipped with equally distributed groove 2, are equipped with buffer in the groove 2
Structure 3, the buffer gear 3 include that cross section is circular cyclic annular cushion 31 and the intermediate buffering in cyclic annular cushion 31
Pad 32, the magnetic yoke main body 1 are equipped with several threaded holes 4, and one end of each threaded hole 4 is connected to a groove 2, and the other end runs through
The rear end of magnetic yoke main body 1, is equipped with adjusting screw rod 5 in the threaded hole 4, the front end of the adjusting screw rod 5 be equipped with protrude into it is recessed
Support base 6 in slot 2, the front end of the support base 6 are equipped with inserting groove 7, and the inserting groove 7 is interior inserted with intermediate buffering pad
32, the internal diameter of the threaded hole 4 is not less than the diameter of groove 2, and the diameter of the intermediate buffering pad 32 is straight slightly larger than inserting groove 7
Diameter, the internal diameter of the ring-type cushion 31 are slightly smaller than the diameter of intermediate buffering pad 32, and the rear end of the ring-type cushion 31 contradicts
On support base 6.
Utility model works process:
A kind of electricity loss brake of the utility model during the work time with magnetic yoke, when cushion needs replacing, adjust by disassembly
It after section screw rod 5 and pulls out, buffer gear 3 pulls out together with adjusting screw rod 5, i.e., replaceable.
