It relates to the method of enclosing.

体例えば合成ゴムや合成樹脂で作られている。FIG. 5 shows a constant velocity joint device equipped with a conventional flexible boot 1. The mounting parts 3 and 4 at both ends of the flexible boot 1 are attached to the outer ring 6 of the joint and the rotating shaft 8 which is inserted into and fixed to the inner ring 7 of the joint, and the outer circumference is tightened and fixed with the coupling band 10, as described above. This prevents the leakage of lubricant and the intrusion of foreign matter from the outside, and maintains a sealed state. The flexible boot 1 has attachment parts 3 and 4 at both ends.
and a bellows part 2 formed in the middle. The flexible boot 1 must be flexible, prevent damage by absorbing the impact of solid objects such as stones flying from the outside and colliding with it, and must itself have the strength to withstand high-speed rotation. For this reason, this type of flexible boot is generally made of a rubber-like elastic material such as synthetic rubber or synthetic resin.

法などがある。The method of sealing lubricant inside the flexible boot 1 is to attach the flexible boot to a constant velocity joint, and before tightening it with the coupling band 10, apply a grease gun or the like from the large-diameter side attachment part 3 or the small-diameter side attachment part 4 of the flexible boot. Insert the nozzle, inject the lubricant, and then attach the connecting band 10.
There is a method of tightening the lubricant, that is, a method of injecting lubricant after installing the flexible boot, or a method of sealing lubricant inside the flexible boot in advance, attaching the flexible boot to a constant velocity joint, and tightening it with a connecting band, that is, installing the flexible boot. There are ways to inject it beforehand.

な知見に基づいてなされたものである。However, in the case of resin flexible boots, the above method of inserting a grease gun and injecting the grease after installing the flexible boots does not allow insertion of a brace gun because the grease has less elasticity compared to rubber flexible boots. In addition, the method of putting lubricant inside the flexible boots and then installing them later requires lubricant to be applied to the inside of the flexible boots, which is inefficient and difficult to install. This has the disadvantage that the lubricant leaks out of the flexible boot or adheres to the inner surface of the mounting part, causing slippage during rotation and twisting the flexible boot. In particular, the inventors of the present invention have focused on the inconvenience of twisting of a flexible resin boot during operation of a constant velocity joint equipped with a flexible boot made of resin. After carefully examining the causes of this, they discovered that the main cause of twisting of the flexible boot is that lubricant adheres to the inner surface of the attachment part when the flexible boot is attached. The present invention has been made based on such knowledge.

する方法、ｔＸ提僕ユれろ。The object of the present invention is to solve the above-mentioned conventional drawbacks, to penetrate the lubricant sealing wall, to facilitate the lubricant injection operation, and to prevent the lubricant from adhering to the inner surface of the mounting portion 3゜4. A flexible resin boot is provided with a lubricant injection port, and the mounting portions at both ends are tightened and fixed to the outer ring of the constant velocity joint and the rotating shaft fixed to the inner ring of the joint. The inside of a flexible boot in a constant velocity joint device, characterized in that after the flexible boot is attached to a constant velocity joint, a lubricant is injected from the injection port into the inner space of the flexible boot, and then the injection port is sealed. How to seal lubricant into space, tX, please tell me.
本発明の方法においては、例えば第１図に示されている

を備えた突起５が形成されている。In the method of the present invention, a flexible boot 1 as shown in FIG. 1, for example, is prepared. The bellows portion 2 of the flexible boot 1 has an injection port 9 that passes through the bellows portion 2.
A protrusion 5 is formed.

口９以外に空気抜き口を設けても良い。Connect the mounting parts 3 and 4 of the flexible boot to the joint outer ring 6.
After the lubricant is attached to the rotating shaft 8 and tightened and fixed with a connecting band 10, lubricant is injected from the injection port 9 of the projection 5. After injection, as shown in FIG. 2, the projection 5 is melted by heating with electricity or gas, or by ultrasonic waves, high frequency waves, etc., and the injection port 9 is sealed. In order to facilitate the injection of lubricant, an air vent may be provided in addition to the injection port 9.
この空気抜き口は、注入口９と同様に潤滑剤注入後には
密封する。Similar to the injection port 9, this air vent port is sealed after the lubricant is injected.

等は設計上の都合により色々と変更することができる。In the example shown in FIG. 3, the above-mentioned protrusion is not provided, and the injection port 9 is made of only a hole. The hole is sealed with a plug 11 such as a grommet as shown in FIG. The position, quantity, shape, etc. of the injection port 9 can be changed in various ways depending on design considerations.

が生じない。In the present invention, since a flexible boot provided with an injection port is used, the required amount of lubricant can be easily injected into the inner space of the flexible boot from the injection port, and when injecting lubricant, the flexible boot is provided with an injection port. Since the large-diameter side attachment portion and the small-diameter side attachment portion of the boot are tightened by the coupling band, no grease adheres to these portions, and therefore problems such as slippage do not occur in the tightened portions during rotation.
