The utility model discloses a concrete implementation scheme is: derailleur axle self-lubricating structure, including the axis body, the axis body is inside to have the fuel feeding chamber, the fuel feeding intracavity has inserted and has supplied oil pipe, the inside cavity of fuel feeding pipe forms the oil feed chamber along circumference laid with the oil pipe of oil feed chamber UNICOM, it has the tip of sealing out oil pipe open-ended to go out oil pipe outside end, the tip goes out oil pipe opening through compression spring fixed connection and elasticity shutoff through compression spring with the periphery that goes out oil pipe, the axis body surface has the oil groove, it stretches into the oil extraction hole who supplies the oil chamber to have the axis body of running through on the oil groove, leave the interval between tip and the fuel feeding intracavity wall, the axis body with supply oil pipe fixed connection.

Furthermore, the outside end of axis body is fixed with flange, the outside of fuel feeding pipe is fixed with the fixed plate, pass through the bolt fastening between fixed plate and the flange and guarantee that the fuel feeding chamber of pivot seals.

Furthermore, the oil outlet pipe is provided with a plurality of oil outlet pipes, and the oil supply cavity in the shaft body is provided with an arc-shaped concave part corresponding to the position of the ejector bead.

Compared with the prior art, the utility model discloses following beneficial effect has: the utility model discloses thereby utilize and open the top pearl through centrifugal force and realize that automatic appropriate amount lubrication reduces the cost with axis body fixed connection's oil pipe rotating the in-process.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

As shown in fig. 1 ~ 3, derailleur axle self-lubricating structure, including the axis body 10, the axis body 10 is inside to have the oil feed chamber 110, the oil feed intracavity is inserted and is supplied oil pipe 20, supply the inside cavity of oil pipe 20 to form the oil feed chamber along circumference laid with the play oil pipe 210 of oil feed chamber UNICOM, play oil pipe outside end has the closed tip 220 that goes out oil pipe open-ended, the tip goes out oil pipe 210 opening through compression spring 230 fixed connection and elasticity shutoff through compression spring with the periphery that goes out oil pipe, axis body surface 10 face has oil groove 120, it stretches into the oil drain hole 121 who supplies the oil chamber to have the axis body to run through on the oil groove, the tip 220 and supply and leave the interval between the oil chamber 110 inner wall, the axis body with supply oil pipe fixed connection.

The oil discharge holes 121 are formed in the oil groove in a plurality of axial directions. The oil outlet pipe is provided with a plurality of compression springs and a plurality of top balls correspondingly.

In this embodiment, thereby the axis body rotates with the axis body of supplying oil pipe fixed connection, and the top ball 220 that is located the opening of oil pipe 210 receives the elasticity shutoff oil pipe 210 opening of spring when initial, thereby later receives the effect of centrifugal force to overcome elasticity and open the opening of oil pipe 210 and realize thereby the outflow of fluid and then get into oil groove 120 through oil drain hole 121 and lubricate.

When the rotation is stopped, the top ball 220 can be retracted by the spring force to block the outlet pipe 210 opening again.

In this embodiment, a connecting flange 30 is fixed to the outer end of the shaft body, a fixing plate 40 is fixed to the outside of the oil supply pipe, and the fixing plate and the connecting flange are fixed through bolts to ensure that an oil supply cavity of the rotating shaft is closed.

In this embodiment, in order to avoid appearing the oil outlet pipe has a plurality ofly, and the axis body internal oil supply chamber has and corresponds the knob position and has arc concave part 130, utilizes the arc concave part can be spacing when knob 220 centrifugation in order to avoid appearing the transition and rock and cause spring wear in arc concave part 130.

Any technical solution disclosed in the present invention is, unless otherwise stated, disclosed a numerical range if it is disclosed, and the disclosed numerical range is a preferred numerical range, and any person skilled in the art should understand that: the preferred ranges are merely those values which are obvious or representative of the technical effect which can be achieved. Because numerical value is more, can't be exhaustive, so the utility model discloses just disclose some numerical values with the illustration the technical scheme of the utility model to, the numerical value that the aforesaid was enumerated should not constitute right the utility model discloses create the restriction of protection scope.

The utility model discloses if disclose or related to mutual fixed connection's spare part or structure, then, except that other the note, fixed connection can understand: a detachable fixed connection (for example using bolts or screws) is also understood as: non-detachable fixed connections (e.g. riveting, welding), but of course, fixed connections to each other may also be replaced by one-piece structures (e.g. manufactured integrally using a casting process) (unless it is obviously impossible to use an integral forming process).

In addition, the terms used in any aspect of the present disclosure as described above to indicate positional relationships or shapes include similar, analogous, or approximate states or shapes unless otherwise stated.

The utility model provides an arbitrary part both can be assembled by a plurality of solitary component parts and form, also can be the solitary part that the integrated into one piece technology was made.

Finally, it should be noted that the above embodiments are only used for illustrating the technical solutions of the present invention and not for limiting the same; although the present invention has been described in detail with reference to preferred embodiments, it should be understood by those skilled in the art that: the invention can be modified or equivalent substituted for some technical features; without departing from the spirit of the present invention, it should be understood that the scope of the claims is intended to cover all such modifications and variations.
