本発明はギヤモー１−ルにおいて、減速機部の潤滑油が
モートル部へ漏れるのを防ぐ為のオイルシールの機能保
持構造に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to a structure for maintaining the function of an oil seal in a gear mole for preventing lubricating oil from a reduction gear part from leaking into a motor part.
従来のギヤモートルにあっては、モートル部と、モート
ル部の回転軸に連結された減速機部とが仕切部材で区画
され、モートル部１よって；減速機部が駆動されたとき
、減速機部の歯車群がその内部に注油された潤滑油によ
って潤滑されるようにしている。In a conventional gear motor, a motor part and a reducer part connected to the rotating shaft of the motor part are separated by a partition member, and when the reducer part is driven by the motor part 1, the reduction gear part is The gear group is lubricated by lubricating oil filled inside the gear group.
また、仕切部材及び回転軸の間にはオイルシールが設置
され、減速機部内の潤滑油が歯車群によって飛散したと
き、オイルシールにより、その潤滑油が仕切部材の回転
軸挿通部を経てモートル部へ漏れるのを防ぐようにして
いる。In addition, an oil seal is installed between the partition member and the rotating shaft, and when the lubricating oil in the reducer part is scattered by the gear group, the oil seal allows the lubricating oil to pass through the rotating shaft insertion part of the partition member to the motor part. This is to prevent leakage.

すると云う点に関しては、充分な配慮がなされていない
。As described above, in conventional gear motors, the main purpose of the oil seal is to prevent the lubricating oil in the reducer from leaking to the mole section, but it is not sufficient to protect the oil seal itself. No consideration was given.
即ち、オイルシールと回転軸との摺動部間には飛散した
潤滑油が入り込んで油膜を形成することにより、双方の
潤滑機能を果しているが、潤滑油には歯車群の摩耗粉が

潤滑機能を低下させるばかりでなく、オイルシールを損
傷させてしまい、しかも回転軸の回転によって生じる熱
によりオイルシールが劣化しやすく、従って、オイルシ
ールの寿命が著しく低下する問題がある。In other words, the scattered lubricating oil enters between the sliding parts of the oil seal and the rotating shaft and forms an oil film, which performs the lubricating function of both, but the lubricating oil is mixed with wear particles from the gears. As a result, the wear particles enter between the sliding parts and not only reduce the lubrication function but also damage the oil seal.Furthermore, the oil seal is easily deteriorated by the heat generated by the rotation of the rotating shaft, and therefore the oil There is a problem that the life of the seal is significantly reduced.
本発明の目的は、上記事情に鑑み、オイルシールを確実
に長寿命化できるギヤモートルにおけるオイルシールの
機能維持構造を提供することにある。In view of the above circumstances, an object of the present invention is to provide a structure for maintaining the function of an oil seal in a gear motor, which can reliably extend the life of the oil seal.
本発明は、仕切部材及びモー１〜ル部の回転軸の間には

させることができる。The present invention provides an oil seal between the partition member and the rotary shafts of the mole 1 and the mole part, which prevents the lubricating oil from entering the reducer part and also serves as a cooling lubricant for the oil seal. It is characterized by forming a space where it can be retained, and retaining the cooling and lubricating oil in the space, and this structure prevents the lubricating oil mixed with wear particles from entering the space. Furthermore, since the cooling and lubricating oil in the space lubricates both the oil seal and the rotating shaft and cools the heat generated by the rotation of the rotating shaft, the life of the oil seal can be reliably extended.

The oil seal 19 is provided between the rotary shaft insertion portion of the partition member 3 and the collar 20 attached to the rotary shaft 4, and is disposed beside the reducer portion 2 of the bearing 10. When the lubricating oil 18 is scattered by the gear group 12, 14, 15, the lubricating oil 18 is prevented from leaking into the motor part 1, and the lubricating oil (not shown) in the bearing 10 is leaked into the reducer part 2. I try to prevent this. For this reason, the rotating shaft insertion portion of the partition member 3 has a groove shaped to accommodate the oil seal 19 (
(not shown) is provided.

リースからなっている。In addition, this lubricating oil 21 is used to prevent wear particles in the lubricating oil 18 from mixing when the lubricating oil 8 of the reducer section 2 begins to enter the gap 24' of the space 22. In order to prevent oil from dripping when applied to a position corresponding to the space 22 of the collar 20 during the assembly process of the five-gear motor, the lubricating oil 18 is made of something more viscous than the lubricating oil 18, such as grease.

and an injection path 26 for injecting the cooling and lubricating oil 21 into the space 22, and these discharge paths 25 are formed at an appropriate time.
Then, the plug 27 fastened to the injection path 26 is removed and the cooling/lubricating oil 21 is replaced to further maintain the function of the cooling/lubricating oil 21.

。The function maintenance structure of the oil seal of the embodiment is as described above.
Oil seal 19 between partition member 3 and rotating shaft 4
A cooling and lubricating oil 21 is reserved in a space 22 provided beside the reducer section 2, and the cooling and lubricating oil 21 forms an oil film between the oil seal 19 and the collar 20 attached to the rotating shaft 4. Oil seal 1
9 can be prevented from deteriorating due to the heat generated by the rotation of the collar 20. At that time, the oil film lubricates both sides, and since the space 22 prevents the lubricant 18 from entering into the reducer section 2, the wear particles in the lubricant 18 are transferred to the cooling lubricant in the space 22. Therefore, the oil seal 1 due to the cooling and lubricating oil 21 is eliminated.
The lubricating function between the collar 9 and the collar 20 can be maintained well.

それがない。In addition, the cooling lubricating oil 21 has higher viscosity than the lubricating oil 18,
Since the space 22 of the collar 20 is not exposed, the lubricant 111 is applied in advance to a position corresponding to the space 22 of the collar 20.
12] If you lubricate the parts, you can assemble the parts smoothly, which improves the assembly workability.
Moreover, even if the wear powder in the lubricating oil 18 were to enter the space 22, the wear powder would be
Since it can be prevented from mixing with 8, there is no risk of deterioration of the lubricating function.
さらに、仕切部材３に排出路２５と注入路２６とが形成

その潤滑油２１の機能が消耗する前にこれを交換すれば
、潤滑油２１の機能をいっそう維持させることができ、
加えてその潤滑油２１の交換作業が部品を取り外すこと
なく容易に行うこともできる。Furthermore, since a discharge passage 25 and an injection passage 26 are formed in the partition member 3, the cooling and lubricating oil 21 can be exchanged from the outside.
If the lubricating oil 21 is replaced before its function is exhausted, the function of the lubricating oil 21 can be further maintained.
In addition, the lubricating oil 21 can be easily replaced without removing any parts.
第３図は本発明の第２の実施例を示している。FIG. 3 shows a second embodiment of the invention.
この場合は、空間部２２と減速機２の内部とを遮蔽する
遮蔽部材２８が設けられている。この遮蔽部材２８は、

つつカラー２０と密接し得るように弾性体で成形されて
いる。In this case, a shielding member 28 that shields the space 22 and the inside of the reducer 2 is provided. This shielding member 28 is
It is disposed between the large groove 23 and the gap 24' in the space 22 in the axial direction, and between the partition member 3 and the collar 20 in the radial direction. This prevents the oil 18 from entering the large groove 23. For this reason, the shielding member 28 is formed of an elastic material so as to allow the collar 20 to rotate and come into close contact with the collar 20.
従って、この実施例によれば、減速機部２の潤滑油１８

２８によって確実に遮蔽するので、空間部２２に対する
摩耗粉の侵入のおそれがなく、従って、摩耗粉による悪
影響をよりいっそう解消できる。Therefore, according to this embodiment, the lubricating oil 18 of the reducer section 2
Even if the lubricating oil 18 is scattered in the direction of the space 22, the lubricating oil 18 is reliably shielded by the shielding member 28, so there is no fear of the abrasion powder entering the space 22, and therefore, the adverse effects of the abrasion powder can be further eliminated.

There is an advantage that the function of the seal can be maintained well, and therefore the life of the oil seal can be reliably extended.
