Abstract

<P>PROBLEM TO BE SOLVED: To provide a hoisting machine for an elevator, using an oil thrower structure as an oil leakage measure for grease from a bearing oil seal of the hoisting machine and also having a dust-proof structure as a performance keeping measure for the oil thrower structure. <P>SOLUTION: In this hoisting machine for an elevator, the oil thrower structure 8 is provided in the midway of an outflow passage so that oil flowing out of the bearing oil seal 7 of the hoisting machine does not reach a braking surface 11. A dust-proof measure is applied to the vicinity of the oil thrower structure 8. As the dust-proof measure, a dust-proof felt also serving to strengthen the protection against oil is provided in the vicinity of the oil thrower structure. <P>COPYRIGHT: (C)2005,JPO&NCIPI

Description

この発明はエレベータ用巻上機の油切り構造に関するものである。   The present invention relates to an oil draining structure for an elevator hoist.

従来のエレベータ用巻上機においては、巻上機の軸受用オイルシール部から流出するグリース等の油漏れ対策として、その連続面に例えばブレーキ制動面等の油に対してもろい部分が存在する場合、ブレーキ制動面に到達しないように油の流出経路の途中に油切り構造を設け、その保護を行う。油切り構造とは油を排出側へ流出させることにより連続面上へ油が付着することを妨げる構造を指す。この油切り構造は形状により効果が決定し、その形状を維持する限りその機能を維持できるという長所がある。従来のエレベータ用巻上機の油切り構造の一例としては、グリース等の油の流出経路上に油切り溝を設け、例えばブレーキ制動面への油の付着を妨げていた（例えば、特許文献１参照）。   In a conventional elevator hoisting machine, as a countermeasure against oil leakage such as grease flowing out from the bearing oil seal part of the hoisting machine, there is a brittle part against oil such as a braking surface on the continuous surface. An oil draining structure is provided in the middle of the oil outflow path so as not to reach the brake braking surface, and protection is provided. The oil draining structure refers to a structure that prevents oil from adhering to the continuous surface by causing the oil to flow out to the discharge side. This oil draining structure has the advantage that the effect is determined by the shape and the function can be maintained as long as the shape is maintained. As an example of the oil drain structure of a conventional elevator hoist, an oil drain groove is provided on an oil outflow path of grease or the like to prevent oil from adhering to, for example, a brake braking surface (for example, Patent Document 1). reference).

特開２００１−６３９３３号公報（図５）Japanese Patent Laying-Open No. 2001-63933 (FIG. 5)

上記従来のエレベータ用巻上機の油切り構造では、その形状を維持する限りその機能を発揮するが、その反面、形状が変化するとその機能が全く損なわれる。例えば、異物の付着等がその例である。
図４は従来のエレベータ用巻上機の下半分を示す断面図、図５はその部分詳細図である。図において、エレベータ用巻上機は、軸１、軸受２、ロープ溝３ａを有する綱車３、ステータ４、磁石５、グリース等の軸受油６、及び軸受２に対しグリース等の軸受油６を保持するためのオイルシール７等を備えている。そして、このオイルシール７より流出した油は、綱車３等の内面を通り、その連続面上にあるブレーキ制動面１１に到達し、制動力を低下させる可能性がある。そこで、通常はその間に位置する綱車３等の内壁面に油切り溝８等の油切り構造を設け、ブレーキ制動面１１への油の付着を防止している。
この防塵機能を持たない従来の油切り構造では、図５に示すように、油切り溝８に付着した油によって異物が付着し易くなり、油切り溝８を短絡するほどの大きさの異物１０が付着した場合には油切りの機能を損なうという問題点があった。 The above-described conventional oil draining structure for an elevator hoist exhibits its function as long as its shape is maintained. On the other hand, if its shape changes, its function is completely impaired. For example, the adhering of foreign matters is an example.
FIG. 4 is a sectional view showing a lower half of a conventional elevator hoisting machine, and FIG. 5 is a partial detail view thereof. In the figure, an elevator hoisting machine has a shaft 1, a bearing 2, a sheave 3 having a rope groove 3 a, a stator 4, a magnet 5, a bearing oil 6 such as grease, and a bearing oil 6 such as grease with respect to the bearing 2. An oil seal 7 or the like for holding is provided. The oil that has flowed out of the oil seal 7 passes through the inner surface of the sheave 3 and the like, reaches the brake braking surface 11 on the continuous surface, and may reduce the braking force. Therefore, an oil draining structure such as an oil drain groove 8 is usually provided on the inner wall surface of the sheave 3 or the like positioned between them to prevent oil from adhering to the brake braking surface 11.
In the conventional oil draining structure having no dustproof function, as shown in FIG. 5, foreign matter easily adheres due to the oil adhering to the oil draining groove 8, and the foreign matter 10 having a size enough to short-circuit the oil draining groove 8. In the case of adhering, there is a problem that the function of oil removal is impaired.

この発明は、上述のような課題を解決するためになされたもので、その目的は、巻上機の軸受用オイルシール部からのグリース等の油漏れ対策として油切り構造を用いるとともに、この油切り構造の性能維持対策として防塵構造を兼ね備えたエレベータ用巻上機を提供するものである。   The present invention has been made in order to solve the above-described problems. The object of the present invention is to use an oil draining structure as a countermeasure against oil leakage from grease oil from a bearing oil seal portion of a hoisting machine. An elevator hoisting machine having a dustproof structure as a measure for maintaining the performance of the cutting structure is provided.

この発明に係るエレベータ用巻上機は、巻上機の軸受用オイルシールから流出した油が、ブレーキ制動面に到達しないように油の流出経路の途中に油切り構造を設けてなるものにおいて、油切り構造の近傍に防塵対策を施したものである。   In the elevator hoisting machine according to the present invention, an oil draining structure is provided in the middle of the oil outflow path so that the oil flowing out from the bearing oil seal of the hoisting machine does not reach the brake braking surface. Dust-proof measures are taken near the oil drain structure.

この発明は以上説明したように、巻上機の軸受用オイルシールから流出した油が、ブレーキ制動面に到達しないように油の流出経路の途中に油切り構造を設けてなるものにおいて、油切り構造の近傍に防塵対策を施したので、油切り構造を短絡する大きさの異物が付着することがなく、油切り機能が損なわれることがない。   As described above, the present invention is provided with an oil drainage structure in the middle of the oil outflow path so that the oil flowing out from the bearing oil seal of the hoisting machine does not reach the brake braking surface. Since dust-proofing measures have been taken near the structure, no foreign matter having a size that short-circuits the oil removal structure is attached, and the oil removal function is not impaired.
