Abstract: Grease fed from a grease tank 10 to a metering force feeder 22 is fed into an injection cylinder 30 after the weight of the grease is precisely measured, and the total amount of the grease in the injection cylinder 30 is injected from the nozzle 34. The nozzle 34 can advance toward an electric motor 60. When the nozzle 34 advances, a first packing 50 and a second packing 52 provided on a tip-end face 34a closely contact to an outer ring 66a and an inner ring 66b of a bearing 66, respectively. In the condition, when the grease is injected from an injection hole 34b, the grease is pushed into an operation space of rolling elements 66c of the bearing 66. A grease pocket 68 is also filled with the grease.

Abstract: A grease packer (10) for packing grease into a bearing (15) has an inner race and an outer race, having a non-rigid bearing holder (11) that defines a conical chamber (12) having a first open end (13) and a second open end (14) through which the bearing (15) may be loaded into the packer (10) with the outer race (16) sitting on the inner wall (17) of the conical chamber (12) and the bearing (16) spaced from the first open end. A non-rigid insert (20) has a first end defined by a stub (22) adapted to pass through the inner race (18) of the bearing (16) located in the conical chamber (12) and a conical outer surface (23) adapted to seat against the inner race (18) of the bearing (16).

Abstract: Wheel assemblies including bearings for inline skates and skateboards with provision for lubricating. In one embodiment, a wheel is supported by the bearings which are in turn supported by an axle/spacer having a central chamber and at least one port extending therethrough to the inner surfaces of the bearings. Screws secure the axle/spacer to wheel supports of an inline skate or skateboard. At least one of the screws includes an interior passageway to accommodate a nozzle for introducing lubricant and/or cleaner under pressure to the central chamber from which it passes through the port or ports in the axle/spacer to the inner surfaces of the bearings. In another embodiment, a wheel includes a hub which is supported by the bearings which in turn are supported by an axle/spacer. The hub has at least one port extending therethrough from the outside to the inner surfaces of the bearings for the introduction of lubricant and/or cleaner under pressure.

Abstract: A bearing lubrication apparatus, including a bearing support stand having a reverse conical stepped cavity therein to support a wheel or other friction bearing assembly, a grease applicator in the form of an open cylinder filled with lubricating grease, and a manually operated piston disposed within the open cylinder to force grease from the cylinder through a bearing raceway supported on one of the horizontal steps of the bearing support stand. As new grease is forced through the bearing raceway, old grease on each individual ball or roller bearing is removed and replaced by new grease. A process for filling the grease applicator involves placing the open cylinder in an inverted position and forcing one open end thereof into a container of highly viscous lubrication grease, placing a finger over the other open end of the cylinder to trap any air therein and create a suction force within the cylinder that retains the contained grease as the cylinder is removed from the grease container.

Abstract: A device for lubricating bearings and the like including a housing for containing a lubricant, and a movable piston adapted to be inserted into the housing in contact with said lubricant. The piston includes an upper concave surface, for communication of the lubricant with a bearing to be lubricated, and a passage for flow of lubricant. Compression of the piston against the lubricant causes flow of lubricant from below the piston to above the piston. An adapter, or volume-filling means, is disposed on the upper piston surface for filing a portion of a volume defined between the upper, concave piston surface and the wheel bearing. The volume-filling means includes lubricant flow passages for allowing lubricant to flow from said upper concave piston surface to the wheel bearing.

Abstract: A system is disclosed for supplying a lubricant to a bearing assembly, such as that in a gyroscope of a spacecraft. The system includes a housing which is connected to the bearing assembly and which forms a pressurized chamber. A collapsible member, such as a bellows, in the pressurized chamber houses a supply of lubricant. One or more valves regulate and control the flow of lubricant from the collapsible member to the bearing assembly. In response to the actuation of the valves, flow of lubricant is caused by pressure exerted on the collapsible member. Lubricant flow conduits may also be formed within the housing, so that lubricant may be provided directly to a portion of the bearing assembly.

Abstract: The crank mechanism of the piston compressor comprises individual crank disks (5), which each support on their outer circumference a rolling bearing (6) for the bearing of a connecting rod (4). The crank disks (5) are pressed together to form a package by means of tensioning bolts (7). The crank case (1) is preferably closed off by a case cover (10), the inside of which is formed as a bearing mount for the crank mechanism. Assembly and disassembly of a crank mechanism of this type is particularly simple and efficient and can be undertaken by personnel who are not specially trained. In addition, special relubrication devices provide simple and error free servicing, and thus greater longevity.

Abstract: A device for injecting grease into a wheel bearing avoids the need for removing the seal ring of the wheel bearing. The device has a hollow mandrel with a closed bottom. A flange extends outward from the mandrel for contact with an inner cage ring of the hearing. A collar extends radially outward from the mandrel above the flange. The collar has an outer edge for contacting the seal ring. The collar is axially movable relative to the flange. A spring urges the collar and flange apart from each other. A port is located in the mandrel between the collar and the flange. A grease fitting allows grease to be introduced into the mandrel to flow out the port, into the space between the collar and the flange, and into the wheel bearing.

In a first preferred embodiment of the invention a stop ring is provided in the housing to limit travel of the piston plate and piston in the housing and the projecting end of the piston is color-coded to indicate the grease content inside the grease housing. In a second preferred embodiment a retainer is attached to the piston for the same purpose.

Abstract: The lubrication insertions system of the present invention inserts lubricating oil into the critical areas of a bearing. The system comprises a delivery element for delivering lubricating oil to a predetermined point relative to the bearing. The bearing, which is rotating, causes the lubricating oil to be slung outward of the spin axis of the bearing. A cage element, having a lip that extends beyond the edge of the bearing, captures the lubricating oil and directs the lubricating oil into the bearing to the outer race of the bearing and to the rolling elements of the bearing, which track the oil to the inner race of the bearing.
