The present invention provides a lubrication device for coating a lubricant onto the outer circumferential surface of a bearing. A lubrication device comprises a housing and a lubrication member that is accommodated within the housing. A bearing crosses and passes through the lubrication member so that an outer circumferential surface of the bearing comes into contact with an inner surface of the lubrication member, and due to this configuration, it becomes possible for the lubricant to be coated onto the outer circumferential surface of the bearing.

It is hereby disclosed a carriage arrangement for lubricating a carriage, wherein the arrangement comprises: a carriage; a carriage beam; a drive mechanism to move the carriage along a longitudinal direction of the carriage beam; and a lubrication roller at a fixed position relative to the carriage beam, the lubrication roller having an outer surface with a non-lubricating section and a lubricating section each at a determined angular position; wherein the carriage is to contact the outer surface as it moves passed the lubrication roller and wherein the contact causes a rotation of the roller that modifies the angular positions of the lubricating section and the non-lubricating section.

An object of the present invention is to provide a chain guide that can improve functional properties of a chain drive system. The chain guide of the present invention is attached to an engine block by a mounting bolt and slidably guides a running chain. The chain guide includes a mounting part provided with a shaft hole through which a mounting bolt is passed, and an oil jet passage for injecting lubricating oil, supplied to the shaft hole at a predetermined pressure, toward the chain.

A bearing housing assembly featuring a bearing housing having a bearing housing wall portion with a bearing assembly chamber for receiving a bearing assembly and a shaft to be rotated, an oil sump for receiving and containing oil for lubricating the bearing assembly when the shaft is rotated, an oil path channel formed as an oil path for receiving dirty oil from the bearing assembly chamber for traveling down the oil path, and a filter assembly wall portion forming a filter assembly cavity coupled fluidically between the oil sump and the oil path channel; and a filter assembly arranged in the filter assembly cavity, to couple to the filter assembly wall portion, receive the dirty oil traveling down the oil path, filter the dirty oil and provide filtered oil to the oil sump, so the filtered oil can be recirculated to lubricate the bearing assembly when the shaft is rotated.

A lubricant coating device preventing coating unevenness of lubricant powders is provided. The lubricant coating device includes a solid lubricant, a coating member and a film shaping member. The coating member in which first fibers composed of a material located on a positive polarity side and second fibers composed of a material located on a negative polarity side, on a triboelectric series with respect to the material of the solid lubricant are implanted, coats lubricant powders scraped off from the solid lubricant onto the image supporter. The film shaping member comes in contact with the image supporter and presses the lubricant powders onto the image supporter, to shape the lubricant powders into a form of a film. A scraping amount of the lubricant powders by the first fibers and a scraping amount of the lubricant powders by the second fibers are set to become substantially identical.
