Description

10 15 20 25 50 55 8105724-2 Üppfinningen beskrivas närmare under hänvisning till bifogade figurer. Fig 1 visar en ändvy och fig 2 ett snitt som A-A i fig 1 anger. 10 15 20 25 50 55 8105724-2 The invention is described in more detail with reference to the accompanying figures. Fig. 1 shows an end view and Fig. 2 shows a section as A-A in Fig. 1.

I figurerna. beteclmar 1 en elektromagnetisk skivbroms som är monterad på en elmotors lagersköld 2 med hjälp av ett azxtal bultar 5. Bromsen 1 innehåller en magnet A bestående av ett magnethus 4 med en spole 5 och en i förhållande till magnethuset 4 axiellt rörlig bromsskiva 6, som utgör magnetens A ankare, en fast bromsskiva 7 och en på motoraxeln 8 monterad roterande bromsskiva 9 med ett antal i öppningar i skivan 9 anbringade friktionskutsar 10 tillverkade av sintemetall med stor slit-styrka.In the figures. beteclmar 1 an electromagnetic disc brake mounted on a electric motor bearing shield 2 by means of an azxtal of bolts 5. The brake 1 contains a magnet A consisting of a magnetic housing 4 with a coil 5 and one in relation to the magnetic housing 4 axially movable brake disc 6, which constitutes the armature of the magnet A, a fixed brake disc 7 and a rotating brake disc 9 mounted on the motor shaft 8 with a number of friction pads 10 mounted in openings in the disc 9 manufactured of synthetic metal with high wear resistance.

Bromsskivan 7 är axiellt fixerad i förhållande till lagerakölden 2 med bultar 5, distanshylsor 11 och muttrar 12. Iiagnethuset 4 med spolen 5 är justerbart axiellt fixerad i förhållande till lagerskölden 2 med justermuttrar 15 på bultarna 5. Dessa justermuttrar 15 är roterbart lagrade i magnethuset 4 och utformade med en fläns 14 och ett spår 15 för en låsring 16 som fixerar dem axiellt i lagersätena 17 i huset 4. Justermuttrarna 15 är utformade med en ut- skjutande, inwräïndigt gängad hylsa 18. Denna utgör styrning för bromsens axiellt rörliga bromsskiva 6, som även utgör magnetens .A ankare. Muttrarna 15 är även utformade med en ursvarvning 19 för en tryckfjäder 20 för ansättning av bromsen.The brake disc 7 is axially fixed in relation to the bearing cold 2 with bolts 5, spacer sleeves 11 and nuts 12. The magnet housing 4 with the coil 5 is adjustable axially fixed in relation to the bearing shield 2 with adjusting nuts 15 on the bolts 5. These adjusting nuts 15 are rotatably mounted in the magnetic housing 4 and formed with a flange 14 and a groove 15 for a locking ring 16 which fixes them axially in the bearing seats 17 in the housing 4. The adjusting nuts 15 are formed with an sliding, internally threaded sleeve 18. This forms the guide for the axial of the brake movable brake disc 6, which also constitutes the .A armature of the magnet. The nuts 15 are also formed with a recess 19 for a compression spring 20 for applying the brake.

När bromsen ansatt bildas ett luftgap a mellan magnethusets 4 polyta och ankaret (bromsskivan) 6. När magxetspolen får ström attraheras ankaret 6 och bromsverkan upphör. Muttrarnas 15 styrningar 18 hindrar ankaret 6 att rotera.When the brake is applied, an air gap a is formed between the polyta of the magnetic housing 4 and the armature (brake disc) 6. When the magnetic coil is energized, the armature 6 and the braking effect ceases. The guides 18 of the nuts 15 prevent the armature 6 from rotating.

Muttrarrxa. är försedda med ett spår 21, ett invändigt sexkantigt hål eller dy- likt för ett justeringsverktyg.Muttrarrxa. are provided with a groove 21, an internal hexagonal hole or similar to an adjustment tool.

Justermuttrarna 15 är fritt åtkomliga, varför justeringen av luftgapet a kan utföras utan att någon bromsdetalj först behöver demonteras. Justeringen kan ske steglöst. Som nämnts kan enkla standardverktyg användas. Genom att juster- muttrarna 15 är belastade av fjädrarna 20 med en ansenlig kraft är risken för att de skall rotera på grund av vibrationer obefintlig. Särskilda låsanord- ningar för justermuttrarna är därför ej nödvändiga.The adjusting nuts 15 are freely accessible, so the adjustment of the air gap a can performed without the need to disassemble the brake part first. The adjustment can happen steplessly. As mentioned, simple standard tools can be used. By adjusting the nuts 15 are loaded by the springs 20 with a considerable force is the risk of that they should rotate due to vibrations non-existent. Special locking devices adjustments for the adjusting nuts are therefore not necessary.

För att förhindra att luftgapet a blir så stort, innan den manuella efterjuste- ringen görs, att magneten ej förmår lyfta ankaret, kan en brygga 22 anbringas över två. av muttrarna 15. Dessabrvvggor är förenade med ankaret (bromsskivan) 6 med bultar 25 och distansrör 24.To prevent the air gap a from becoming so large, before the manual readjustment If the magnet is not able to lift the anchor, a bridge 22 can be fitted over two. of the nuts 15. These nuts are connected to the anchor (brake disc) 6 with bolts 25 and spacers 24.

Bromsen är mycket servicevänlig. Magnethusst 4 med spole 5 kan lätt bytas. En- dast låsringarna 16 och de eventuella bryggorna 22 behöver avlägsnas. Vid utbyte av friktionskutsarna 10 behöver därutöver endast justermuttrarna 15 skruvas bort.The brake is very service-friendly. Magnetic housing 4 with coil 5 can be easily replaced. One- only the locking rings 16 and the possible bridges 22 need to be removed. In exchange of the friction liners 10, in addition, only the adjusting nuts 15 need to be unscrewed.
