Description

A kind of electromagnetic disc type brake

Technical field

The utility model relates to the break technical field, particularly a kind of electromagnetic disc type brake.

Background technique

Traditional drum-type, the structure more complicated of disk type braker, its volume is bigger, and adjust, maintenance is inconvenient, under many working conditions, owing to can't use by the restriction of installation conditions and installing space, as adopt hydraulic pressure jaw type braking device, must be equipped with hydraulic station again, the same like this cost is just than higher, maintenance difficulty is big, break is generally single brake disc of electromagnetism dead electricity braking at present, it mainly comprises and is used for the connecting wheel that is rotationally connected synchronously with the motor output revolving shaft, its spinning that endwisely slips only is furnished with brake disc in the outer circumferential face upper edge of connecting wheel, be separately installed with armature and mounting plate in the both sides of brake disc, on armature and the mounting plate with on the corresponding side surface of brake disc the friction plate that is used to oppress brake disc is being installed, side away from brake disc of armature is provided with and is used for the yoke that is connected with motor base, corresponding side surface with armature on the yoke is provided with electromagnetic coil, be provided with along yoke with the corresponding side surface of armature on the yoke and extend axially spring mounting hole, be provided with pressure spring in the mounting hole, an end roof pressure of pressure spring is on the side of armature.Above-mentioned single brake disc is when electromagnetic coil is switched on, electromagnetic coil work, make it away from brake disc armature absorption, this moment the pressure spring pressurized, brake disc is not worked, rotating shaft is rotated further, when dead electricity, electromagnetic coil is not worked, and the restoring force of pressure spring forces armature to be pressed on the brake disc, brake disc is subjected to friction plate surface friction drag, thereby realizes the countershaft braking.But safe operation is had in the place of specific (special) requirements at some,, often adopts the break of two stacks, and the break that adopts stack complex structure not only in order to realize bigger braking moment, and itself and install also inconvenient.

The model utility content

The purpose of this utility model provides the big and electromagnetic disc type brake simple in structure of a kind of braking moment.

For achieving the above object, the utility model adopts following technological scheme: a kind of electromagnetic disc type brake, comprise the connecting wheel that is used for the yoke that is connected with pedestal and is used for being connected with rotating shaft, its spinning that endwisely slips only is furnished with brake disc in the outer circumferential face upper edge of connecting wheel, be provided with armature with the yoke corresponding matching in a side of the close yoke of brake disc, opposite side at brake disc is provided with the mounting plate of fixedlying connected with yoke, on the bi-side of brake disc, be equipped with friction plate, described brake disc is along connecting two brake discs that axial parallel is provided with, be provided with transition disc between two brake discs, on the end face of the close brake disc of yoke, be installed with axially extended sliding pin along connecting wheel, transition disc and armature are provided with the pilot hole with the corresponding cooperation of sliding pin, and transition disc and armature are slidedly assemblied on the sliding pin by pilot hole.

Described mounting plate is arranged on the yoke by adjusting bolt, and the equal flip sleeve of armature and transition disc is contained in to be adjusted on the bolt.

In the utility model with the outer circumferential face of the connecting wheel of rotating shaft coaxial rotation assembling on only revolve two brake discs of slidable fit, a transition disc is set between two brake discs, so just effectively improved the braking moment of break, and itself is simple in structure, processing easily, the production of break integral body, installation and maintenance cost are lower, are convenient to market and use.

Fig. 3 is an A-A place sectional view among Fig. 2.

Embodiment

As Fig. 1, Fig. 2, shown in Figure 3, a kind of electromagnetic disc type brake, comprise and be used for the yoke that is connected with motor base 5 and be used for and the coaxial connecting wheel that is connected 13 of output revolving shaft, it endwisely slips and ends two brake discs 2 that spinning is furnished with parallel setting in the outer circumferential face upper edge of connecting wheel 13, only revolve and be slidingly matched by being arranged on the internal spline on the brake disc and being arranged on external splines on the connecting wheel outer circumferential face between brake disc 2 and the connecting wheel 13 in the present embodiment, be provided with armature 3 with yoke 5 corresponding matching in a side of the close yoke 5 of brake disc 2, in the groove corresponding to the end face of armature 3 of yoke 5, be provided with electromagnetic coil 9, yoke 5 with armature 3 corresponding end faces on also be provided with along the axially extended spring mounting hole of yoke, at spring mounting hole pressure spring 6 is installed, one end roof pressure of pressure spring 6 is on the corresponding end face of the close yoke of armature 3, opposite side at brake disc 2 is provided with by adjusting the installation version 1 that bolt 10 is fixedlyed connected with yoke 5, between two ends brake disc 2, be provided with transition disc 20, be provided with friction plate on the both ends of the surface of brake disc, on the end face of the close brake disc 2 of yoke 5, be installed with axially extended sliding pin 7 along connecting wheel, at transition disc, offer pilot hole on armature and the mounting plate with the corresponding cooperation of sliding pin, transition disc, armature and mounting plate are slidedly assemblied on the sliding pin 7 by pilot hole, and sliding pin 7 is fixed on the yoke 5 by fixing bolt.

Mounting plate is connected on the yoke 5 by adjusting bolt 10 in the foregoing description, is provided with and adjusts bolt 10 corresponding unthreaded holes on armature 3 and transition disc 20, and armature 3 and transition disc 20 are by unthreaded hole and adjustment bolt 10 slidable fit.

Mounting plate 1 is realized axial restraint by the tightening nut 12 and the adjustment nuts that are installed in the mounting plate both sides, is being provided with the lock washer 11 that is sleeved on the adjustment bolt 10 between tightening nut 12 and the mounting plate 1.

External splines only revolves and is slidingly matched in adopting between connecting wheel and brake disc in the foregoing description, when specifically implementing, can also adopt other only to revolve structure, as adopt inside and outside gear engagement.

The utility model in use, when work mechanism is worked, electromagnetic coil 9 gets electric generation suction, armature 3 moves to yoke 5 directions under the effect of electromagnetic attraction, compressing pressure spring 6, and unclamp roof pressure to brake disc 2, this moment, brake disc 2 separated with armature 3, transition disc 20, mounting plate 1, realized declutching.

When needs are braked, electromagnetic coil 9 outages, electromagnetic attraction disappears, pressure spring 6 discharges, promote armature 3 and move and push brake disc 2, transition disc 20 and mounting plate 1 to brake disc 2 directions, this moment, brake disc 2 was subjected to the extrusion friction resistance of armature 3, transition disc 20 and mounting plate, brake disc 2 is squeezed and stops operating under the effect of surface friction drag, because brake disc is connected with the rotating shaft coaxial rotation by connecting wheel, rotating shaft is stopping operating under the effect under the effect of braking moment surface friction drag, realizes brake sticking brake.

Adjustment bolt 10 in the foregoing description uses when being everlasting manual work, when being in an emergency or have a power failure maintenance, break is in the band-type brake state, unscrew this moment and adjust bolt 10, fully discharge pressure spring 6, remove the pressure of 3 pairs of brake discs 2 of armature, transition disc 20 and mounting plate 1, realize declutching.In the specific implementation, need to guarantee to adjust the design length of bolt, to guarantee to discharge pressure spring.
