Abstract
The utility model discloses an electricity-loss brake for AC servo electrical machinery, which is composed of a flange (8), a magnetic yoke (1), an armature (4), a coil (2), and a fixed friction plate (7). The piston of the armature (4) is positioned on the flange (8); a pressure spring piece (5) is arranged between the armature (4) and the fixed friction plate (7); the two sides of the pressure spring piece (5) are provided with friction pieces (6); the pressure spring piece (5) is fixed on the convex platform of the flange (8). A hole is opened on the magnetic yoke (1), and a spring (3) is inserted and arranged in the hole. The utility model has the advantages of simple structure, high speed, no empty load force moment, etc.
Description
The utility model is the AC servo motor power-off brake, is contained on the rotor shaft of AC servo motor as executive component.
At present, domestic friendship commonly used roll actuating motor with power-off brake often from external import, though the break of import can satisfy the brake request of AC servo motor, its structure is complicated, price is expensive, retro-speed slow and few steadily, have a unloaded moment.
Task of the present utility model be to provide a kind of simple in structure, retro-speed fast and steadily, the AC servo motor power-off brake of no unloaded moment.
Task of the present utility model is finished like this, a kind of AC servo motor power-off brake, form by flange (8), yoke (1), armature (4), coil (2), fixed friction plate (7), existing armature (4) kink is on flange (8), between armature (4) and fixed friction plate (7), be provided with pressure spring sheet (5), pressure spring sheet (5) two sides are provided with friction plate (6), pressure spring sheet (5) is fixed on the boss of flange (8), on yoke (1), have the hole, be embedded spring (3) in the hole.
The utility model is because after adopting above-mentioned design, simplify the structure, owing between armature (4) and fixed friction plate (7), be provided with pressure spring sheet (5), and be provided with friction plate (6) in its two side, so when braking, retro-speed is fast and steady, because armature (4) is movable, so under non-braking situation, armature (4) can overcome spring (3) resistance and by yoke (1) adhesive, between armature (4) and friction plate (6) and friction plate (6) and fixed friction plate (7), certain space can occur like this, thereby eliminate unloaded moment.
Below in conjunction with accompanying drawing the utility model is further described below.
Accompanying drawing is the utility model structural drawing.
Friction plate of the present utility model (6) is bonded in two sides of pressure spring sheet (5) respectively with adhesive material.On the boss of sending out blue (8), open several screws, pressure spring sheet (5) is fixed on the boss, then flange (8) is contained on the rotor shaft of AC servo motor with screw (12).
The coil (2) that produces magnetic force when energising is housed in the yoke of the present utility model (1), yoke (1), coil (2), armature (4) are formed closed magnetic circuit, yoke (1) is contained on the AC servo motor casing, armature has the hole on (4), device retainer ring (9) in the hole, retainer ring (9) is enclosed within on the socket head screw (10), retainer ring (9) is a Spielpassung with armature (4), the hole that is armature (4) is slightly larger than retainer ring (9), so that armature (4) can be gone up the axially activity of doing at retainer ring (9).Fixing with yoke (1) by socket head screw (10) then fixed friction plate (7), retainer ring (9), so just fixed friction plate (7), retainer ring (9), yoke (1) three are fixed.Have several holes on the circumference of yoke of the present utility model (1), embed spring (3) in each hole respectively, the end of spring (3) contacts with armature (4).When coil (2) no electric circuit, just the elastic force by spring (3) ejects armature (4), and armature (4) and yoke (1) are thrown off.
When interchange department clothes electrical power, be fixed on its rotor axis of electric in just running thereupon of flange (8), because pressure spring sheet (5) is to be fixed on the boss of flange (8), and friction plate (6) is again two sides that are bonded in pressure spring sheet (5), so when flange (8) rotated, pressure spring sheet (5), friction plate (6) be rotation thereupon just.At this moment, make coil (2) energising by wiring terminal (11), coil (2) produces magnetic force with yoke (1), at this moment armature (4) overcome spring (3) resistance and by adhesive, to be armature (4) at retainer ring (9) go up does moving at interval, thereby is just producing the gap and the zerofriction force distance between the friction plate (6) of armature (4) and pressure spring sheet (5) one sides and between the friction plate (6) of pressure spring sheet (5) opposite side and fixed friction plate (7); When the AC servo motor dead electricity, coil (2) is dead electricity just, coil (2) loses magnetic force with yoke (1), the restoring force of spring (3) is just arranged this moment and armature (4) is ejected, thereby make between the friction plate (6) of armature (4) and pressure spring sheet (5) one sides and the friction plate (6) and the disappearance of the gap between the fixed friction plate (7) of pressure spring sheet (5) opposite side.Armature (4) and fixed friction plate (7) clamp with the friction plate (6) of pressure spring sheet (5) two sides respectively, thereby produce the frictional force distance,, rapidly rotor shaft is braked apart from braking the rotor shaft of AC servo motor by this frictional force to reach effectively in the moment of AC servo motor dead electricity.
Claims (2)
1, a kind of AC servo motor power-off brake, form by flange (8), yoke (1), armature (4), coil (2), fixed friction plate (7), it is characterized in that armature (4) kink is on flange (8), between armature (4) and fixed friction plate (7), be provided with pressure spring sheet (5), pressure spring sheet (5) two sides are provided with friction plate (6), pressure spring sheet (5) is fixed on the boss of flange (8), has the hole on yoke (1), is embedded spring (3) in the hole.
2, AC servo motor power-off brake according to claim 1, it is characterized in that having the hole on the armature (4), device retainer ring (9) in the hole, retainer ring (9) is enclosed within on the socket head screw (10), retainer ring (9) is a Spielpassung with armature (4), and is fixing with yoke (1) fixed friction plate (7), retainer ring (9) by socket head screw (10).
