Description

本発明は、エレベーターにおける、ブレーキ装置のストローク自動調整機構に関するものである。   The present invention relates to an automatic stroke adjusting mechanism for a brake device in an elevator.

エレベーターのロープを巻き上げる巻上機にはブレーキ装置が搭載されており、緊急時には、回転している巻上機のディスクまたはドラムに、ブレーキ装置のライニングを押し当て、相互に発生する摩擦力によってエレベーターを停止させている。ブレーキ装置を使用すると、摩擦力によってライニングの表面は摩耗する。すると、ライニングが摩耗した分、ライニングのストロークが増え、ライニングを押し付けるバネの伸び量が増えるので、押し付け力が弱くなり、制動力が低下する。また、ライニングが摩耗した分、ブレーキ解除時のディスクまたはドラムとライニングとの隙間が大きくなるので、ライニングのストロークが増え、クランプ時の騒音が大きくなる。このため、緊急停止時後は、ライニングのストロークを再調整する必要があった。（例えば特許文献１参照）。   The hoisting machine that winds up the rope of the elevator is equipped with a braking device. In an emergency, the lining of the braking device is pressed against the rotating disk or drum of the hoisting machine, and the elevator produces the frictional force that is generated mutually. Is stopped. When the brake device is used, the surface of the lining is worn by frictional forces. Then, since the lining is worn, the stroke of the lining increases and the amount of extension of the spring that presses the lining increases, so the pressing force becomes weak and the braking force decreases. Moreover, since the gap between the disc or drum when releasing the brake and the lining increases due to the wear of the lining, the lining stroke increases and the noise during clamping increases. For this reason, it was necessary to readjust the lining stroke after an emergency stop. (For example, refer to Patent Document 1).

実施の形態１．
図１ないし図５を用いて、本発明の一実施の形態における、ストローク自動調整機構について説明する。図１はブレーキの全体構成を示し、図２は変位部材２０、図３はストローク調整部材３０を示す図である。また、図４は、図１のブレーキにおいて、ライニング３が摩耗する前の状態を示し、図５は、ライニング３が摩耗した状態を示している。Embodiment 1 FIG.
An automatic stroke adjustment mechanism according to an embodiment of the present invention will be described with reference to FIGS. FIG. 1 shows the overall configuration of the brake, FIG. 2 shows a displacement member 20, and FIG. 3 shows a stroke adjustment member 30. 4 shows a state before the lining 3 is worn in the brake of FIG. 1, and FIG. 5 shows a state where the lining 3 is worn.

図１において、ライニング３は、保持部材１０に保持されて、ストローク調整部材３０に連結されている。ストローク調整部材３０は第１雄ねじ部４０を有し、第１雄ねじ部４０は、アーマチュア１の第１雌ねじ部４１に螺合されている。ストローク調整部材３０の第１雄ねじ部４０を、第１雌ねじ部４１に対して締める方向あるいは緩める方向に回転させることにより、ライニング３の摩擦面５と、ブレーキディスク２の制動面４との距離、すなわちライニング３のストロークを調節することができる。   In FIG. 1, the lining 3 is held by a holding member 10 and connected to a stroke adjusting member 30. The stroke adjusting member 30 has a first male screw portion 40, and the first male screw portion 40 is screwed to the first female screw portion 41 of the armature 1. The distance between the friction surface 5 of the lining 3 and the braking surface 4 of the brake disk 2 by rotating the first male screw portion 40 of the stroke adjusting member 30 in the tightening direction or the loosening direction with respect to the first female screw portion 41, That is, the stroke of the lining 3 can be adjusted.

図１において、ライニング３の摩擦面５には、少なくとも一か所の穴が設けられ、変位部材２０が挿入されている。図２に示すように、変位部材２０は、先端に第１傾斜面５０を有し、後端は曲面形状とされている。そして、変位部材２０は、先端の第１傾斜面５０をストローク調整部材３０側に向け、後端がライニング３の摩擦面５と一致するように、ライニング３の穴に挿入される。なお、変位部材２０の後端は、曲面以外の形状、例えば平坦でもよい。   In FIG. 1, the friction surface 5 of the lining 3 is provided with at least one hole, and a displacement member 20 is inserted therein. As shown in FIG. 2, the displacement member 20 has the 1st inclined surface 50 in the front-end | tip, and makes the rear end into a curved-surface shape. The displacement member 20 is inserted into the hole of the lining 3 so that the first inclined surface 50 at the front end faces the stroke adjusting member 30 and the rear end coincides with the friction surface 5 of the lining 3. The rear end of the displacement member 20 may have a shape other than a curved surface, for example, a flat surface.

図３に示すように、ストローク調整部材３０のライニング３側には、ライニング３に設けられた、変位部材２０を挿入する穴位置に対応する位置に、第２傾斜面５１を有する穴が設けられている。ストローク調整部材３０の各第２傾斜面５１は、各変位部材２０の第１傾斜面５０に当接するように調整される。なお、図３には、３つの円弧状の長穴を有するストローク調整部材３０が記載されているが、この数および形状に限定されるものではない。例えば、長穴は２つあるいは４つ以上でもよく、また、１つの環状の長穴の中に、複数の第２傾斜面５１を形成してもよい。   As shown in FIG. 3, a hole having a second inclined surface 51 is provided on the lining 3 side of the stroke adjusting member 30 at a position corresponding to the hole position in the lining 3 where the displacement member 20 is inserted. ing. Each second inclined surface 51 of the stroke adjustment member 30 is adjusted so as to contact the first inclined surface 50 of each displacement member 20. Although FIG. 3 shows the stroke adjusting member 30 having three arc-shaped elongated holes, the number and shape are not limited to this. For example, the number of the long holes may be two or four or more, and a plurality of second inclined surfaces 51 may be formed in one annular long hole.

次に、図４、および図５を用いて、ライニング３が摩耗するのに伴い、変位部材２０が変位する過程を説明する。図４に示すように、ライニング３が摩耗する前は、変位部材２０の後端は、ライニング３の摩擦面５の位置にある。ブレーキが稼働すると、ライニング３はブレーキディスク２の制動面４に押し付けられて摩耗する。   Next, a process in which the displacement member 20 is displaced as the lining 3 is worn will be described with reference to FIGS. 4 and 5. As shown in FIG. 4, before the lining 3 is worn, the rear end of the displacement member 20 is at the position of the friction surface 5 of the lining 3. When the brake is operated, the lining 3 is pressed against the braking surface 4 of the brake disk 2 and is worn.

図５において、ｄは、ライニング３の摩耗量を示している。変位部材２０の後端は、ライニング３の摩擦面５と同時にブレーキディスク２の制動面４に当接するので、変位部材２０は、ライニング３が摩耗するのに伴い、制動面４に押圧されて、ライニング３の摩耗量ｄと同じ量だけ、ライニング３に押し込まれる方向に変位する。   In FIG. 5, d indicates the amount of wear of the lining 3. Since the rear end of the displacement member 20 contacts the braking surface 4 of the brake disk 2 simultaneously with the friction surface 5 of the lining 3, the displacement member 20 is pressed against the braking surface 4 as the lining 3 wears, The lining 3 is displaced in the direction of being pushed into the lining 3 by the same amount as the wear amount d.

変位した変位部材２０の第１傾斜面５０は、ストローク調整部材３０の第２傾斜面５１を押圧する。押圧されたストローク調整部材３０の第１傾斜面５１は、変位部材２０の押圧力を、ストローク調整部材３０の第１雄ねじ部４０を、アーマチュア１の第１雌ねじ部４１に対して緩める方向の回転力に変換する。そして、ストローク調整部材３０は、ライニング３を、ブレーキディスク２に近づける方向に変位させる。   The displaced first inclined surface 50 of the displacement member 20 presses the second inclined surface 51 of the stroke adjusting member 30. The first inclined surface 51 of the pressed stroke adjusting member 30 rotates the pressing force of the displacement member 20 in the direction to loosen the first male screw portion 40 of the stroke adjusting member 30 with respect to the first female screw portion 41 of the armature 1. Convert to force. Then, the stroke adjusting member 30 displaces the lining 3 in a direction approaching the brake disc 2.

以上、本実施の形態１によれば、摩耗したライニング３の摩耗量に応じて、ライニング３の摩擦面５と、ブレーキディスク２の制動面４との距離、すなわち、ライニング３のストローク量を調整することができる。   As described above, according to the first embodiment, the distance between the friction surface 5 of the lining 3 and the braking surface 4 of the brake disk 2, that is, the stroke amount of the lining 3 is adjusted according to the wear amount of the worn lining 3. can do.

なお、実施の形態１では、アーマチュア１に第１雌ねじ部４１を設けたが、この位置に限定されるものではない。例えば、図６に示すように、ストローク調整部材３１を、軸受７０と係止部材７１を用いてアーマチュア１に支持し、保持部材１１に、ストローク調整部材３１の雄ねじ部４２と螺合する雌ねじ部４３を設けてもよい。   In the first embodiment, the first female screw portion 41 is provided in the armature 1, but is not limited to this position. For example, as shown in FIG. 6, the stroke adjusting member 31 is supported by the armature 1 using a bearing 70 and a locking member 71, and the holding screw 11 is screwed with the male screw portion 42 of the stroke adjusting member 31. 43 may be provided.

また、実施の形態１では、変位部材２０の先端を第１傾斜面５０としたが、この形状に限定されるものではない。例えば、図７に示すように、変位部材２１の先端を球状にしてもよいし、図８に示すように、変位部材２２の先端に、回転自在なローラー２５を備え、ストローク調整部材３１の第２傾斜面５１に、ローラー２５の回転面を当接させるようにしてもよい。   Moreover, in Embodiment 1, although the front-end | tip of the displacement member 20 was made into the 1st inclined surface 50, it is not limited to this shape. For example, as shown in FIG. 7, the tip of the displacement member 21 may be spherical, or as shown in FIG. 8, the tip of the displacement member 22 is provided with a rotatable roller 25, and the first of the stroke adjustment member 31. The rotating surface of the roller 25 may be brought into contact with the two inclined surfaces 51.

実施の形態２．
図９は、本発明の実施の形態２における、ストローク自動調整機構である。本実施の形態２におけるストローク自動調整機構は、変位部材２３と、第１かさ歯車８０と、第１かさ歯車８０と噛合う第２かさ歯車８１と、ストローク調整部材３２とを備えている。Embodiment 2. FIG.
FIG. 9 shows an automatic stroke adjustment mechanism according to Embodiment 2 of the present invention. The automatic stroke adjustment mechanism according to the second embodiment includes a displacement member 23, a first bevel gear 80, a second bevel gear 81 that meshes with the first bevel gear 80, and a stroke adjustment member 32.

変位部材２３の先端には、第１かさ歯車８０の被係合部８３に係合する係合部８２が設けられており、第２かさ歯車８１は、ストローク調整部材３２に固定されている。また、ストローク調整部材３２には、第２雄ねじ部４４が設けられ、保持部材１２に設けられた第２雌ねじ部４５に螺合されている。   At the distal end of the displacement member 23, an engagement portion 82 that engages with the engaged portion 83 of the first bevel gear 80 is provided, and the second bevel gear 81 is fixed to the stroke adjustment member 32. Further, the stroke adjusting member 32 is provided with a second male screw portion 44 and is screwed into a second female screw portion 45 provided on the holding member 12.

ライニング３が摩耗すると、変位部材２３が変位して、変位部材２３の先端に設けられた係合部８２が、第１かさ歯車８０に設けられた被係合部８３を介して、第１かさ歯車８０を回転させる。第１かさ歯車８０が回転すると、第１かさ歯車８０と噛合う第２かさ歯車８１が回転するので、第２かさ歯車８１が固定されたストローク調整部材３２が回転する。すると、保持部材１２の第２雌ねじ部４５に対して、ストローク調整部材３２の第２雌ねじ部４４は、ストローク調整部材３２を保持部材１２から引き抜く方向に回転し、保持部材１２と、保持部材１２に保持されたライニング３を、ブレーキディスク２の方へ移動させる。   When the lining 3 is worn, the displacement member 23 is displaced, and the engaging portion 82 provided at the distal end of the displacement member 23 is moved through the engaged portion 83 provided in the first bevel gear 80 to the first bevel. The gear 80 is rotated. When the first bevel gear 80 rotates, the second bevel gear 81 that meshes with the first bevel gear 80 rotates, so that the stroke adjusting member 32 to which the second bevel gear 81 is fixed rotates. Then, the second female screw portion 44 of the stroke adjusting member 32 rotates in the direction of pulling out the stroke adjusting member 32 from the holding member 12 with respect to the second female screw portion 45 of the holding member 12, and the holding member 12 and the holding member 12 are rotated. The lining 3 held in the position is moved toward the brake disc 2.

以上、本実施の形態２によれば、摩耗したライニング３の摩耗量に応じて、ライニング３のストローク量を調整することができる。   As described above, according to the second embodiment, the stroke amount of the lining 3 can be adjusted according to the wear amount of the worn lining 3.

実施の形態３．
図１０は、本発明の実施の形態３における、ストローク自動調整機構である。図１０に示すように、本実施の形態３におけるストローク自動調整機構は、変位部材２４と、ストローク調整部材３３と、歯車９０とを備えている。Embodiment 3 FIG.
FIG. 10 shows an automatic stroke adjustment mechanism according to Embodiment 3 of the present invention. As shown in FIG. 10, the automatic stroke adjustment mechanism according to the third embodiment includes a displacement member 24, a stroke adjustment member 33, and a gear 90.

歯車９０は、一方向にのみ回転可能とされ、ストローク調整部材３３を、ブレーキディスク２の方向にのみ移動可能とする。変位部材２４は、歯車９０と噛合う第１の櫛刃９１を有し、ストローク調整部材３３は、歯車９０と噛合う第２の櫛刃９２を有している。また、第１の櫛刃９１と第２の櫛刃９２は、互いに対向させて、歯車９０に係合されている。   The gear 90 can be rotated only in one direction, and the stroke adjusting member 33 can be moved only in the direction of the brake disc 2. The displacement member 24 has a first comb blade 91 that meshes with the gear 90, and the stroke adjustment member 33 has a second comb blade 92 that meshes with the gear 90. The first comb blade 91 and the second comb blade 92 are engaged with the gear 90 so as to face each other.

ブレーキが稼働して、ライニング３の摩擦面５がブレーキディスク２の制動面４に押圧されると、ストローク調整部材３３には、ストローク調整部材３３をアーマチュア１側に移動させる力が働くが、歯車９０が回転しないため、移動することはない。ライニング３が摩耗すると、変位部材２４がアーマチュア１側に変位し、変位部材２４の先端に設けられた第１の櫛刃９１が歯車９０を回転させる。すると、ストローク調整部材３３は、変位部材２４と逆の方向へ移動し、保持部材１３に保持されたライニング３を、ブレーキディスク２の方へ移動させる。   When the brake is operated and the friction surface 5 of the lining 3 is pressed against the braking surface 4 of the brake disk 2, a force that moves the stroke adjustment member 33 toward the armature 1 acts on the stroke adjustment member 33. Since 90 does not rotate, it does not move. When the lining 3 is worn, the displacement member 24 is displaced toward the armature 1, and the first comb blade 91 provided at the tip of the displacement member 24 rotates the gear 90. Then, the stroke adjusting member 33 moves in the direction opposite to that of the displacement member 24 and moves the lining 3 held by the holding member 13 toward the brake disk 2.

以上、本実施の形態３によれば、摩耗したライニング３の摩耗量に応じて、ライニング３のストローク量を調整することができる。   As described above, according to the third embodiment, the stroke amount of the lining 3 can be adjusted according to the wear amount of the worn lining 3.
