Description
Technical field
The present invention relates to a kind of in order to be attached to friction type emergency brake on a drive motor or the speed changer, that use electromagnetic mode loosening.
Background technique
Known in the prior art polytype this attached brake.The similar break that the applicant is proposed in WO01/59317A1 is considered to immediate prior art.In this immediate prior art, the electromagnetic brake with two coils is attached on a motor or the speed changer.Described break itself is arranged in the inner chamber of roughly cup-shaped driving disc, and moment of torsion externally is delivered to toward on the break by driving disc, and this can find out by WO01/59317A1 accompanying drawing 6 is clear.The closed circuit break (Ruhestrombremse) that is installed in the electromagnetism in the annular cavity of cup-shaped driving disc utilizes a plurality of cylinder head bolts to be screwed on the shell of a speed changer that is not shown specifically or motor, and driving disc is fixedlyed connected with speed changer or motor equally.Described cup-shaped driving disc almost completely surrounds the whole break that comprises the brake rotor that is used to produce braking moment.
By from the known structure of foregoing immediate prior art, a kind of very compact break-wherein break can be fully integrated in driving disc though can be provided with, and the shortcoming of this structure is must remove driving disc when keeping in repair.Described in addition structure needs a corresponding or complicated wire guide device so that be the power supply of the electromagnetic coil of break.When must change, just need very whole this device of taking apart of intricately to the friction covering face of brake rotor.In addition, also because the maximum outside diameter of break only may keep less relatively,, its consequence correspondingly has been limited thereby being exactly the maximum braking moment of break.
Summary of the invention
So the objective of the invention is to, such break is further transformed, making can be more easily near break, simultaneously, just can simply assemble under the situation of the position that does not need to change significantly transmission pulley.
Should also provide a kind of unit of compactness in addition, wherein break can be attached on a motor or the speed changer easily with transmission pulley.
Another object of the present invention is a kind of brake structural with bigger brake rotor friction radius to be set, so that obtain higher maximum braking moment in this way.
For this reason, the invention provides a kind of in order to be attached on a drive motor or the speed changer, friction type emergency brake with electromagnetic mode loosening, have: one is arranged in the break and can be axially movable with respect to brake shell antitorquely, the armature disc of the twinset that spring pressure loads, in order to form a double loop break, two in break with the field coil of the adjacent setting of armature disc of described twinset, one around cup-shaped driving disc, it wraps up each parts of break and can be connected by axially movable brake rotor with one on its annular end face antitorquely, wherein, the armature disc of described twinset when the field coil no electric circuit, exerted pressure by spring force and with the brake rotor frictional engagement, it is characterized in that, the shell of attached brake constitutes bearing cap, it is simultaneously as the coil case that holds field coil and spring assembly, and, bearing cap have one at a side shaft to outstanding central protuberance, in order to the bearing journal of the far-end of the outside that forms supporting cup-shaped driving disc.
The shell of attached brake constitutes bearing cap (end shield), and it is simultaneously as the coil case that holds field coil and spring assembly, and described spring assembly produces the necessary impacting force of braking of brake rotor.Described in addition bearing cap has in the central protuberance of a side shaft in outstanding, casting, and in order to the bearing journal of the far-end of the outside that forms a supporting cup-shaped driving disc, the excircle of driving disc is preferably in the axial direction towards the direction indentation of bearing cap.
Preferably, flanged plate with circular structure is arranged on the inside of the driving disc of cup-shaped, wherein, flanged plate is stamped axial distance with bearing and relative bearing cap is provided with antitorquely, make when field coil no electric circuit spring force that the armature disc of twinset is pressed on the brake rotor, and described brake rotor is pressed on the flanged plate.
In the design of the double loop break with the brake components that works alone each other, such attached brake is widely used in lift.

Embodiment
Relate to a kind of electromagnetism double loop break at this with two field coils (interior field coil 2, outer field coil 3).In case above-mentioned two coil electricities will produce the electromagnetic field of armature disc 7 and external armature dish 6 in the attraction.Thereby rotor 13 can freely be rotated with two friction covering faces 14 and 15.Braking moment is delivered on the driving disc 17 from rotor 13 by drive bolt 16 (8).Flanged plate 10 is connected with brake shell 1 by dividing bush 11 and clamping bolt 12 on a plurality of positions, and brake shell comprises part A, B and C, asks for an interview list of numerals.The driving disc 17 bearing journal C by a bearing 18 and the far-end of brake shell 1 rotatably still axial restraint ground be connected. Armature disc 6 and 7 axial motion can obtain and carry out electrification and handle by a microswitch 21 of each brake circuit.Thereby can express, when armature disc 6 and 7 is attracted with when break is freely.Push control rod 22 and driver plate 23 are as the axial motion of interior armature disc 7 is transmitted outward.The axial motion of external armature dish 6 can directly (not have driver plate) and seizes by a microswitch 21 via a push rod 22.
Four interval pins 26 that stretch into counterbore 20 are only as whole unit is fixed on the motor or speed changer that drives driving disc 17.Motor and speed changer are not shown specifically in the drawings, can design as requested.For the connection set that is connected to driving disc by binding thread 19 also is same.
Two coils of break are directly installed among the bearing cap A, and bearing cap also utilizes the bearing journal C supporting transmission pulley of its far-end.This bearing cap or shell additionally also have base and the internal points that are used for four interval pins, by means of them this assembly are installed on the motor.By two coils are incorporated in the bearing cap, can be better near break and electric connection, for example winding wire and the microswitch that is used to unclamp (release) monitoring.Break and friction disk and bearing cap can be formed a construction package that is easy to mount and dismount jointly.
Owing to the long and narrow structure of break and by break is incorporated in the shell, friction radius can be designed to surpass the driving disc diameter, thereby reaches high moment of torsion.
Driving disc 17 is connected with motor by binding thread 19.Thereby driving disc can be by motor driven.
