Abstract: The passage of a container along a conveyor is lubricated by applying to the container or conveyor a mixture of a water-miscible silicone material and a water-miscible lubricant. The mixture can be applied in relatively low amounts, to provide thin, substantially non-dripping lubricating films. In contrast to dilute aqueous lubricants, the lubricants of the invention provide drier lubrication of the conveyors and containers, a cleaner conveyor line and reduced lubricant usage, thereby reducing waste, cleanup and disposal problems.

Abstract: A greasing system for conveyor belt rollers uses a depression formed in a shaft about which the roller rotates to permit grease to flow from a front side to a backside of a roller bearing. In this way grease can be applied to the bearing while the conveyor is operating. The grease then flows from the backside of the bearing, through the bearing and out an outlet on the front side of the bearing making it easy to determine when the bearing has been fully greased.

Abstract: The invention relates to a rotating shaft apparatus for rotationally driving a spindle or a feed screw shaft and a machine tool including the rotating shaft apparatus, and is directed to enhance durability of a rotating shaft apparatus if the rotating shaft such as a spindle or a feed shaft rotates at a high speed.

Abstract: A roller for a continuous track on a crawler tractor or the like comprises two sections welded together to define an interior lubrication cavity which communicates by means of lubrication passages to spaces containing bearings and to an exterior lubrication port. Liquid plastic material capable of in situ foaming to form an open cell plastic mass is injected into the cavity and passages wherein it sets into an open cell plastic mass. Subsequently, lubricating oil or grease is injected under pressure through the lubrication port to fill the open cells of the plastic mass for storage and subsequent supply to the bearings through the lubrication passages. The open cell plastic mass also provides a barrier or filter for particles of contaminants disposed in the cavity as a result of welding and other manufacturing steps and prevents circulating of such particles with the lubricant and damage to the bearings and seals.

Abstract: A system for lubricating flexible clutches and couplings while they are in motion. There are two shafts provided, one that is driving and another that is driven, connected to one-another by means of a flexible clutch which may be formed from two forked arms held flexibly to one another by means of small stud shafts. These shafts, in the process of operation, have a way to become wornout, and it is rather important that lubricating grease may be delivered to them to decrease friction, Grease is delivered to a stationary housing within which is rotatably mounted a circular disk. The disk is connected to the drive shaft and to the driven shaft. Grease passes from the housing into the disk and is then conducted to the bearing points of the clutch.

Abstract: A track roller for a continuous track on a crawler tractor or the like comprises two sections welded together to define an interior lubrication cavity which communicates by means of lubrication passages to spaces containing bearings and to an exterior lubrication port. The track roller has a central cavity with a foam material holding a lubricant in its open cells. Axles extend from the track roller and through which a passage extends to communicate with the cavity. The axles are supported by bearings in the caps that are fixedly and non-rotatably mounted on the frame that supports the track roller. The passage in each axle permits lubricant to pass from the cavity to the bearings.
