And, having the directing pin 171 of rubber ring 173 to be inserted under the state of bullport 172a with chimeric, the peripheral part elastic deformation of rubber ring 173 and with the inner peripheral surface butt of bullport 172a.That is, movable core 172 flexibly is supported on arm 111 via rubber ring 173 and directing pin 171, and movable core 172 forms by rubber ring 173 sliding guidances.In addition, the degree of depth of bullport 172a forms the following degree of depth: can take in directing pin 171, and can and be connected to arm 111 with movable core 172 attractions.
Be provided with magnet coil 176 in being of arm 111 circle-shapedly,, erect towards roller 105 outer peripheral faces and to be provided with two springs 174 in the inboard of magnet coil 176 with movable core 172 opposed sides.In Fig. 7; Magnet coil 176 is under excited state; The application force that overcomes spring 174 is adsorbed in arm 111 with movable core 172, thereby makes braking parts 150 leave roller 105, forms thus and between the outer peripheral face of the friction part material 169 of braking parts 150 and roller 105, produces gap g.In Fig. 8, under magnet coil 176 erasing states, 174 pairs of movable core 172 application of forces of spring, thus braking parts 150 is pressed on roller 105.
In Fig. 7, be provided with correction portion 161 in braking parts 150, this correction portion 161 makes friction part material 169 push or revise when separating the posture of friction part material 169 with respect to roller 105.Have the boots 166 that are fixedly connected with friction part material 169, spherical zone seat 162, spherical crown seat 164 and as the elastic clip 168 of the second elastic portion material in correction portion 161.
Figure 11 show along the arrow VII of Fig. 6 to view, Figure 13 show along the arrow VI-VI of Fig. 5 to view.Base portion like two elastic clip 168 of Figure 11, ground shown in Figure 13 arranged opposite is fixed in movable core 172 through screw 167; The terminal part of the sheet of said two elastic clip 168 is pressed the roller 105 opposed faces sides of pressure shoes 166, through elastic force boots 166, spherical crown seat 164, spherical zone seat 162 is pushed and is remained in movable core 172.
Figure 14 illustrates the scheme drawing of elastic clip 168 by the position of pressure shoes 166.Elastic clip 168 be arranged near the of dummy line 166a by the position of pressure shoes 166 and at the both ends of boots 166 side, said dummy line 166a is that roller 105 opposed faces of virtual plane 165 and boots 166 of center-point 162a of spherical zone that comprise pivot center 105a and the spherical zone seat 162 of roller 105 intersect the line that obtains.
The end of elastic clip 168 forms as illustrated in fig. 11 and leans on end thin more more, thereby can push down the certain location of boots 166 like this.
In addition, in this embodiment, elastic clip 168 leans on end thin more more, but also the projection (not shown) of convex can be set in the part by pressure shoes 166 of the terminal part of elastic clip 168, and presses pressure shoes 166 with this jut.
The method of decomposing brake equipment 101 and checking etc. with reference to Fig. 5, Fig. 6 explanation operator when safeguarding.In Fig. 5, the operator unloads with the bolt 114 of stay hook 117 with the bolt 113 that arm 111 is anchored on installation portion 103b when safeguarding.The bolt that is screwing togather 112 is unclamped so that arm 111 can rotate slightly.Then, when being that drive division 170 moved to the position of leaving roller 105 with braking parts 150 after fulcrum rotated arm 111 as illustrated in fig. 6 with bolt 112.Thus, form the part of can Visual Confirmation being blocked by roller 105.
After inspection wait to finish, through according to above-mentioned opposite step assembling, thereby brake equipment 101 is restored.
At brake equipment 101, when friction part material 169 being pressed on the outer peripheral face of roller 105, can send clash in order to brake.In order to reduce this clash, the gap width g between the outer peripheral face of friction part material 169 and roller 105 is adjusted into predetermined value.The method of adjustment of said gap width g is described with reference to Fig. 5, Fig. 6.
The operator determines the gap width g before the adjustment when safeguarding, then unloads with the bolt 114 of stay hook 117 with the bolt 113 that arm 111 is anchored on installation portion 103b, and bolt 112 is unclamped so that arm 111 can rotate slightly.Then, be that fulcrum rotates arm 111 with bolt 112 as illustrated in fig. 6.
In order to make gap width g reach anticipated value; Preprepared liner 115 with preset thickness value t is clipped between arm 111 and the installation portion 103b; Once more arm 111 is fastened on installation portion 103b with bolt 113; And arm 111 is fixed in installation portion 103a with bolt 112, after this, hook 117 is fixed in installation portion 103b with bolt 114.Like this, can change above-mentioned gap width g according to the one-tenth-value thickness 1/10 t of liner 115.
In addition, liner 115 can only be a slice, also can be that multi-disc is overlapping.
Braking, the action of releasing of brake equipment 101 are described with reference to Fig. 7, Fig. 8.Fig. 7 shows that roller 105 unclamps with respect to friction part material 169 and the state that can rotate.
At this moment, energising makes its excitation to magnet coil 176, and the extending force that overcomes spring 174 is adsorbed in arm 111 with movable core 172, elastic deformation the peripheral part and the inner peripheral surface butt of bullport 172a of rubber ring 173, with maintenance movable core 172.Thus, between the outer peripheral face of friction part material 169 and roller 105, form gap g, roller 105 forms and can rotate.
Under the releasing orientation of Fig. 7, when forming erasing state when the electric current that cuts off magnet coil 176, spring 174 elongations, thereby to movable core 172 way rollers, the 105 side application of forces and move it.The mode that movable core 172 slides with respect to the peripheral part of rubber ring 173 with the inner peripheral surface of bullport 172a is directed and moves.Then, as shown in Figure 8, movable core 172 move to make braking parts 150 friction part material 169 by the position of the outer peripheral face that is pressed in roller 105 to brake.
Under the braking mode of Fig. 8, when making magnet coil 176 become excited state, overcome the extending force of spring 174, movable core 172 is drawn and moves to arm 111 side draughts.And movable core 172 moves to and is adsorbed in till the arm 111.The mode that movable core 172 in moving slides with respect to the peripheral part of rubber ring 173 with the inner peripheral surface of bullport 172a is directed and to arm 111 side shiftings.Thus, between the outer peripheral face of friction part material 169 and roller 105, form gap g, roller 105 forms and can rotate.
Like this, thus rubber ring 173 produce elastic deformations and with the inner peripheral surface butt supporting movable core 172 of bullport 172a, thereby and said rubber ring 173 with respect to the inner peripheral surface of bullport 172a the moving of guiding movable core 172 of sliding.
With reference to Fig. 8, Figure 14 brake equipment 101 braking, the action of correction portion 161 when unclamping are described.At glancing impact, when making when pressing on roller 105, be the attitude change that the mode of outer peripheral face makes friction part material 169 and boots 166 along the brake surface of roller 105 with the brake surface of friction part material 169 with roller 105 opposed friction part materials 169.That is, because drive division 170 presses on the power of roller 105 with friction part material 169, the clamped position skew of spherical zone seat 162 and spherical crown seat 164, and elastic clip 168 is with the mode elastic deformation of distortion, and friction part material 169 changes with the posture of boots 166 with respect to roller 105.At this moment, the posture of friction part material 169 and boots 166 changes along the direction of the arrow M of Figure 14.So the brake surface of friction part material 169 is pushed along the outer peripheral face of roller 105 equably.
Then, action when unclamping is described.When friction part material 169 pressed on roller 105, elastic clip 168 was in the state that has produced elastic deformation and twisted to the direction of the arrow M of Figure 14.Then, when drive division 170 made friction part material 169 leave roller 105, the recuperability of elastic clip 168 played a role to eliminate said distortion.On the other hand, because spherical zone seat 162 and spherical crown seat 164 receive the pressing force of elastic clip 168, therefore friction force is arranged in the effect of the engagement section of spherical zone seat 162 and spherical crown seat 164.In addition, because elastic clip 168 is near dummy line 166a and the both end sides of boots 166 by the position of pressure shoes 166, the recuperability of therefore eliminating distortion is little and littler than the friction force of engagement section.Thus, even friction part material 169 separates with respect to roller 105, friction part material 169 still keeps the posture identical with the state that is pressed with boots 166.Thereby, the gap width g approximate equality between friction part material 169 and the roller 105.
The brake equipment 101 that constitutes as described above has following effect.
In Fig. 5, the operator unloads with the bolt 114 of stay hook 117 with the bolt 113 that arm 111 is anchored on installation portion 103b when safeguarding, and the bolt 112 that will be fixed in installation portion 103a unclamps so that arm 111 can rotate slightly.Then, when being that drive division 170 moved to the position of leaving roller 105 with braking parts 150 after fulcrum rotated arm 111 as illustrated in fig. 6 with bolt 112.Thus, exposed by the part that roller 105 blocks, it is easy that Visual Confirmation becomes.
Under this state, for example, use screwdriver that screw 167 is unloaded, can braking parts 150 easily be decomposed.That is, can be when safeguarding easily drive division 170 and braking parts 150 be decomposed to check etc.
In addition, at brake equipment 101, with braking parts 150 direct mounts in drive division 170.Thus, need not to be used to make the linkage portion material or the link gear of drive division 170 and braking parts 150 interlocks.Therefore, can make the device that constitutes by drive division 170 and braking parts 150 become small-sized, so brake equipment 101 also become small-sized.
In addition; At brake equipment 101, when elevator was worked, an end of the arm 111 of brake equipment 101 utilized bolt 112 to be fixed in installation portion 103a; The other end of the arm 111 of brake equipment 101 utilizes bolt 113 to be fixed in installation portion 103b; Even therefore braking, arm 111 also are difficult for producing fine motion, can access stable braking force.
In addition, also can replace the tapped bore 103c of installation portion 103a and the hole is set, and replace bolt 112 and adopt pin.(not shown) according to said structure, the trouble of when rotating arm 111, not unclamping bolt 112.
In addition, thus hook 117 remains on installation portion 103b with arm 111 and makes arm 111 not rotate across the head of bolt 113.Thus, even lose the fastening force of bolt 113, the braking force of brake equipment 101 can not lose yet.
In addition; In this embodiment; To form as the shape of the hook 117 that rotates anti-stop element across bolt 113 and the other end that keeps arm 111; But, even being formed the other end of avoiding bolt 113 and directly being connected to arm 111, the shape of hook 117 keeps in case the moving shape of spline also can access same effect.
In addition; In brake equipment 101, when the gap width g between the outer peripheral face of friction part material 169 and roller 105 is adjusted into predetermined value, under the state that arm 111 has been rotated; Clip the liner 115 of one-tenth-value thickness 1/10 t, utilize bolt 113 that arm 111 is anchored on once more and keep seat 103.
Through changing the one-tenth-value thickness 1/10 t of liner 115 like this, can change gap width g, so the adjustment operation of gap width g becomes easy.
In addition; At brake equipment 101; Movable core 172 by elastic support in rubber ring 173; And, movable core 172 is being attracted to arm 111, or when movable core 172 being moved, is being embedded in rubber ring 173 among the groove 171a of terminal part of directing pin 171 and slides with respect to the inner peripheral surface of the bullport 172a of movable core 172 and guide movable core 172 to move with 174 pairs of movable cores of spring, 172 way rollers, the 105 side application of forces.
Thus, movable core 172 can move swimmingly.
In brake equipment 101, owing to have a correction portion 161, therefore when the pushing of the friction part material 169 of braking parts 150, can the brake surface of friction part material 169 roughly be pressed on equably the outer peripheral face of roller 105.Therefore, the braking force of brake equipment 101 is stable.
When separating; The brake surface of friction part material 169 leaves the outer peripheral face of roller 105 with keeping posture identical when pushing; Therefore can make the gap width g approximate equality between the outer peripheral face of friction part material 169 and roller 105, the operation that gap width g is adjusted in the preset range becomes easy.
In addition; As shown in Figure 9; In this embodiment, between arm 111 and installation portion 103b, accompany a liner 115 and utilize bolt 113 fastening, but also can be: as illustrated in fig. 10; Between arm 411 and installation portion 403b, press from both sides side by side along the pivot center direction of roller 105 and to establish two kinds of different liners of one-tenth-value thickness 1/10 415 with liner 416 and utilize bolt 113 fastening.
One end of arm 411 utilizes bolt 112 to be installed in the installation portion 403a that keeps seat 403, and the other end of arm 411 utilizes bolt 113 to be installed in installation portion 403b.And the movable core 172 of being located at arm 411 makes friction part material 169 push with respect to roller 105 or separate.But, owing to arm 411, keep the manufacturing errors of seat 403, exist arm 411 and be mounted to respect to being the hand of rotation out-of-position situation at center with vertical axle.Under this state, arm 411 tilts with respect to the outer peripheral face of roller 105, and movable core 172 makes friction part material 169 push obliquely with respect to roller 105 or separate.Under said situation; Press from both sides the liner 415 and liner 416 of establishing two kinds of one-tenth-value thickness 1/10s side by side through pivot center direction between arm 411 and installation portion 403b along roller 105; Revised the inclination of arm 411 with respect to the outer peripheral face of roller 105, thus be used to make friction part material 169 push with respect to roller 105 or the action of the movable core 172 that separates stable.
In this embodiment, as shown in Figure 7, between arm 111 and installation portion 103b, accompany rectangular-shaped liner 115, but also can press from both sides the liner 615 of establishing wedge-like as illustrated in fig. 15.Folder is established the liner 615 of wedge-like between arm 611 and installation portion 103b, utilizes bolt 113 that arm 611 is anchored on installation portion 103b.Arm 611 tilts with equal angular with the bearing surface of liner 615.For fear of liner 615 from arm 611 and installation portion 103b between expose, bolt 619 tractives and fixed-bearing 615, said bolt 619 are located at the check plate 618 with installation portion 103b and arm 611 butts.
The method of adjustment of folder being established the gap width g under the situation of liner 615 of wedge-like describes.Arm 611 bolt 112 unclamped slightly, so that can be that fulcrum rotates with bolt 112.On one side bolt 113 is unclamped on one side bolt 619 is tightened, this moment, liner 615 was inserted into so that the distance between installation portion 103b and the arm 611 increases, and gap width g increases.
On the contrary, when on one side bolt 619 being unclamped when on one side bolt 113 being tightened, liner 615 is pushed out, and the distance between installation portion 103b and the arm 611 diminishes, and gap width g diminishes.Therefore, when the liner 615 of establishing wedge-like when folder between arm 611 and installation portion 103b came the adjusting play, rand was confirmed the limit adjustment gap width g of variation continuously easily.
In this embodiment; As shown in Figure 7; Change the one-tenth-value thickness 1/10 t that is clipped in the liner 115 between arm 111 and the installation portion 103b and come adjusting play value g; But also can between movable core 172 and spherical zone seat 162, press from both sides and establish laminal pad, the thickness that changes this pad comes adjusting play value g (not shown).
Method of adjustment is: rotate arm 111, folder has been made as and has made gap width g reach anticipated value and the pad of preprepared preset thickness value between movable core 172 and spherical zone seat 162, and then arm 111 is anchored on installation portion 103b.Through making the one-tenth-value thickness 1/10 thickening or the attenuation of pad, can reduce or increase gap width g like this.
Comparing with the method for adjustment of establishing liner 115 at folder between arm 111 and the installation portion 103b in method of adjustment that folder between movable core 172 and the spherical zone seat 162 is established pad like this, is more to adjust near the position as the gap at adjustment position.That is, the portion's material quantity between position of adjusting and the gap that will adjust is few, so loosening etc. the influence between each material is little, and the precision of adjustment improves, and adjusts operation thus and becomes easy.
In this embodiment; Like Fig. 7, shown in Figure 11; The directing pin that is embedded with rubber ring 173 171 is inserted among the bullport 172a that is located at movable core 172, but also can is as illustrated in fig. 12, erect at arm 511 four directing pin 171 are set; Four angles with directing pin 171 opposed movable cores 572 are provided with circular-arc groove 572a, and the part of the rubber ring 173 among the groove 171a that is embedded in directing pin 171 is engaged with groove 572a.With the peripheral part of the opposed rubber ring 173 of groove 572a slightly elastic deformation and with groove 572a butt.That is, movable core 572 flexibly is supported on arm 511 via rubber ring 173 and directing pin 171, and movable core 572 forms by rubber ring 173 sliding guidances.
When movable core 572 moved, groove 572a slided with respect to rubber ring 173 and guides movable core 572 to move.Thus, movable core 572 can move swimmingly.
In addition, rubber ring 173 exposes always, can easily carry out the visual inspection to the state of the state of rubber ring 173 and slipper.
In this embodiment; As shown in Figure 7, utilize the elastic force of elastic clip 168 that movable core 172 is pushed and remained in to boots 166, spherical crown seat 164, spherical zone seat 162, but; Use spherical zone seat even replace elastic clip 168, also can access same effect (not shown) with magnetic force.Movable core, spherical zone seat, recessed spherical crown seat, boots link together through magnetic attraction each other.When the friction part material is pressed, the clamped position of spherical zone seat and recessed spherical crown seat skew, thus friction part material and boots with respect to the roller outer peripheral face towards change, the brake surface of friction part material is pressed the outer peripheral face of pressing roller equably.Thus, braking force is stable.
When separating; Pass through magnetic force; The friction part material leaves the outer peripheral face of roller with keeping posture identical when pushing, so the gap width approximate equality between the outer peripheral face of the brake surface of friction part material and roller, and the operation that gap width g is adjusted in the preset range becomes easy.In addition, need not the fixing screw of elastic clip is loaded and unloaded, decompose, the stack-mounted operation becomes simple and easy.
The 3rd embodiment
According to Figure 16 the 3rd embodiment of the present invention is described.In second embodiment; Method of adjustment as the gap width g between friction part material 169 and the roller 105; Folder is established liner 115 between arm 111 and installation portion 103b, yet in this embodiment, utilizes screw bolt and nut to adjust the distance between arm 111 and the installation portion 103b.In addition, for the component parts identical with other embodiment labels, expression is with a part and omission explanation in this embodiment.
The method of adjustment of gap width g is described.Two nuts 320 that are screwed together in bolt 313 are unclamped, and bolt 112 is unclamped slightly so that arm 111 can be that fulcrum rotates with bolt 112.When under this state, tightening or unclamping bolt 313, gap width g changes, and therefore adjusts so that gap width g reaches predetermined gap width g.After adjustment, two nuts 320 are tightened, and bolt 112 is tightened.
According to this embodiment, can when confirming the gap width g that changes serially, easily adjust operation.
In addition, in this embodiment, used a bolt 313, yet also can be set up in parallel two bolts 313 (not shown) in the pivot center direction of roller 105.Because manufacturing errors exists arm 111 and the uneven situation of the mutual opposed opposed faces of installation portion 103b.Under said situation, the degree that is screwed into of adjusting each bolt 313 just can be revised the inclination of arm 111.Thus, be used to make friction part material 169 push with respect to roller 105 or the action of the movable core 172 that separates stable.
