起に゛より潤滑油が鎖の継手へ飛散される。In order to disperse the lubrication of the chain immersed in the oil bath, it was developed in Germany to catch the oil thrown away by the chain with a guide strip with a U-shaped cross section and return this oil to the inside of the chain through a pipe. It is known from the Federal Republic of Patent Application Publication No. 1ρ30123. It is also known to provide a play gap between the inner and outer metal plates of the chain to facilitate the entry of lubricating oil. However, these measures only provide incomplete lubrication, especially when the chain transmission is operated at high speeds. This is because when the chain is immersed in an oil bath or splashes an oil stream, not enough lubricating oil reaches the joints of the chain where it should perform its lubrication and cooling role. be. This is disclosed in US Pat. No. 3,528,526, in which a capsule containing a lubricant is provided between two coaxial pongees each having a chain wheel, and the double chains on the chain wheels of both swords form a type of shaft joint. However, such a lubrication device cannot be accommodated in a timing silver chain transmission. This also applies to the conveyor chain known from French Patent No. 2,408,679 aS. The conveyor chain is provided with a rotatable disc with projections that engage the chain, and these projections spray lubricating oil onto the joints of the chain.

出とに役だつ油の流通を行なうことができる。According to the invention, this object is achieved by providing a feed opening in the joint of the chain consisting of bottle, sleeve and possibly roller. By providing such supply openings, when the chain is immersed into the oil bath or splashes oil, each supply opening receives a certain amount of oil and directs it towards the bottle, thereby forming an oil film. , an oil flow can be provided which serves for cooling and for removing any wear particles present.

れに応じて定めることができる。In an advantageous embodiment of the invention, each sleeve and possibly each roller is provided with a radial feed opening, or each bin has a central hole extending to the middle of its length, which is followed by a radial hole. , if rollers are provided on the sleeve, the sleeve can have radial holes. In the case of rolled sleeves, the openings are preferably formed by punching out semicircular notches when punching out the sleeve in its stretched form. If a directed oil jet is splashed onto the chain, the direction of the feed opening can be determined accordingly when manufacturing the chain.

As a result, the oil initially present is forced out and once the load on the chain is removed, oil is sucked back into the cavity where it now resides. This results in an advantageous PtJJ distribution of the strands.

ちろんである。The sleeve chain according to FIG. 1 consists of an inner metal sheet 1, a sleeve 2, an outer metal sheet 3 and a pin 4. The inner sheet metal 1 is fixed to the sleeve 2, and the outer sheet metal 3 is fixed to the bin 4 located in the sleeve i. The sleeve 2, which is in the form of a rolled sleeve and a groove, has a supply opening 5 through which lubricating oil flows in the direction of the arrow 6 when the sleeve chain is immersed in an oil bath or is exposed to an oil jet. Then, it reaches the sliding partner consisting of the sleeve 2 and the bottle 4 of the chain link. The supply opening 5 can be provided at any location on the sleeve 2. These feed openings are preferably formed by semicircular punching of the abutting edge of the unrolled sleeve during the punching of the sleeve. During manufacture of the chain, these feed openings are oriented so that oil enters them. Of course, instead of a round feed volume lower, any cross section can be provided.

。In the case of the sleeve chain according to FIG. 2, a central hole 7 is provided in the bottle 4 as a feed opening for lubricating the spigot joint, and this hole 7 is followed by a radial hole 8 opening into the circumferential surface of the bottle 4. There is. This arrangement is particularly suitable for directing an oil jet from the side in the direction of arrow 9 onto the sleeve chain in order to lubricate the chain.

向穴をもつことができる。In the roller bearing according to FIG. 3, the rollers 11 are seated on a sleeve 2 that connects the inner sheet metal 1. In the roller bearing according to FIG. In order to introduce sufficient lubricating oil into sleeve 2, sleeve 2
The annular end face 12 of is interrupted by a recess 13 which serves as a feed opening. Lubricating oil accumulates in the notch 13 and reaches the gap between the sleeve 2 and a pin (not shown) in the direction of the arrow 14. In order to lubricate the rollers 11 which fit onto the sleeve 2, the sleeve 2 can have radial holes as in the embodiment of FIG.

吸込まれる。In the sleeve chain according to FIGS. 4 and 5, the sleeve 2 has an enlarged hole 15 as a feed opening which extends conically from its longitudinal center to both ends. This allows a sufficient amount of lubricating oil to reach between sleeve 2 and pin 4 in the direction of arrow 16. When the sleeve chain and therefore the chain links are loaded, the contact between the sleeve 2 and the pin 4 takes place continuously from the inside to the outside as the load increases. As a result, the lubricating oil is pushed out in the direction of arrow 17, and when the load on the sleeve chain is removed, the course of movement of the lubricating oil is reversed and it is sucked in again in the direction of arrow 16 into the then created cavity.
こうしてスリーブ２上 流通が採血される。Thus the top of sleeve 2 Blood is drawn from circulation.
