A transmission lubricating structure includes a power transmitting shaft, a main lubricating circuit, and an auxiliary lubricating circuit. The power transmitting shaft includes an ejection hole communicating an inside with an outside of the power transmitting shaft. The main lubricating circuit includes: a main nozzle having a nozzle hole through which lubricating oil supplied from a main tank is discharged to the internal space of the power transmitting shaft; and a hydraulic pump configured to supply the lubricating oil by pressure from the main tank to the main nozzle. The auxiliary lubricating circuit includes an auxiliary nozzle arranged lower than an auxiliary tank and higher than a lubrication target at the outside of the power transmitting shaft, the auxiliary nozzle being configured to drop the lubricating oil, supplied from the auxiliary tank by an own weight of the lubricating oil, toward the lubrication target.

A laser processing machine includes a guide member with which a laser head is engaged so as to be movable to one side in a conveying direction, a moving device configured to move the laser head along the guide member, a counterweight which is movably engaged to the other side of the guide member in the conveying direction and moves along the guide member in a direction opposite to a moving direction of the laser head in conjunction with the laser head moved by the moving device, and a control device which controls the moving device to move the counterweight to a position facing the grease feeding device and to perform grease feeding to an engaged portion between the counterweight and the guide member.

The present invention relates to a grease replacement method of replacing grease in a case (84) including a sealable gear chamber (31, 36) accommodating a gear (85) as a member to be lubricated, a grease injection port (61, 62) configured to inject grease into the gear chamber (31, 36), and a discharge port (32, 37) configured to discharge the grease in the gear chamber (31, 36), and a grease suction device to be used to perform this method. The grease replacement method includes a suction step (S2) of sucking the grease in the gear chamber (31, 36) from the grease injection port (61, 62) with the discharge port (32, 37) being open, and discharging the grease outside the case (84), and an injection step (S4) of injecting new grease into the grease injection port (61, 62) and supplying the new grease to the gear (85). This facilitates discharging of old grease.

A tire bead lubricating system for applying lubricant to a tire consists of a frame supporting conveyor belts which form a conveyor opening therebetween. The conveyor belts transfer a tire from one end of the frame to another. A lubricating wick chamber is maintained within the frame and positioned underneath the conveyor opening. A lubricating wick assembly is received in the lubricating wick chamber and moves into the conveyor opening. The lubricating wick assembly has at least one engagement roller and at least one elongate brush that carries lubricant applied to the tire.

When an annular portion of a thrust collar rotates together with a rotating shaft member, centrifugal force and shear force, or differential pressure caused by difference in flow rate are generated in lubricating oil in a circulation oil chamber. With this, the lubricating oil in the circulation oil chamber is guided from the inner peripheral side to the outer peripheral side of the annular portion, through a circulation hole penetrating the annular portion. The flow of lubricating oil guided by the circulation hole forms a flow of lubricating oil from a lower oil chamber to an upper oil chamber through the circulation oil chamber. As a result, the lubricating oil stored in the lower oil chamber is circulated to the upper oil chamber through the circulation oil chamber, by rotation of the thrust collar.

Disclosed herein is a system includes a lubricated component and a lubricant pump that selectively provides lubricant to the lubricated component. The system also includes a lubricant source in lubricant providing communication with the lubricant pump. Additionally, the system includes a lubricant flow regulation device in lubricant receiving communication with the lubricated component and lubricant providing communication with the lubricant source. The lubricant flow regulation device is configured to drain lubricant from the lubricated component to the lubricant source based on when the lubricant pump provides lubricant to the lubricated component, and to prevent drainage of lubricant from the lubricated component to the lubricant source based on when the lubricant pump stops providing lubricant to the lubricated component.
