A volumetric lubricant dispensing apparatus for delivering a precise volume of lubricant, such as oil, to a rotating machine element. The delivery mechanism includes a piston and cylinder assembly. A plurality of sensors are utilized to record operating conditions of the machine, element, environment, and lubricant. The apparatus is controlled either manually or with the aid of a controller unit such as a microprocessor. The output from each sensor is inputted into the microprocessor wherein an algorithm computes an responsive output. The responsive output is sent to the piston and cylinder assembly, which maintains an optimum lubricant condition within the reservoir wherein a rotating machine element located. Alternatively, for the purpose of qualitative control, the present invention may be described as a system intended for controlling lubricants, both mineral (natural) and synthetic based by measuring the condition characteristics of the lubricant. Some condition characteristics may include water or moisture content (the content could be any liquid, e.g., solvents like ketones are known to change condition characteristics like viscosity) and viscosity. Viscosity is related to temperature, therefore, temperature correlation to viscosity is helpful to provide relative indications for condition characteristics like lubricant flow.

Devices, systems, and methods are disclosed which relate to a catheter cap which seals a reservoir of a catheter introducer. The catheter cap secures over an introducer tip to prevent airflow into the introducer tip. The catheter cap utilizes an elongated stem to block a distal opening of the reservoir to further prevent airflow. A lip of the catheter cap may further engage an insertion stop point of the catheter introducer to secure the catheter cap. The catheter cap ensures proper lubrication of the introducer tip and the catheter during insertion of the catheter into the urethra of a user.

A reduction gear is mounted on a revolving frame, and an electric motor having an electric motor shaft is disposed on the reduction gear. A hydraulic motor having a shaft is disposed on an upper side of the electric motor. A shaft insertion hole through which an upper end side of the electric motor shaft is inserted is provided in a lid portion of an electric motor casing. A male spline portion provided on the hydraulic motor shaft is spline-coupled to a female spline portion provided on the electric motor shaft. A bearing is provided between the shaft insertion hole and the electric motor shaft, and a pressure tight seal is provided by being located upwardly of the bearing. Hence, spline coupling portions of the female spline portion and the male spline portion are constantly lubricated by making use of drain oil which has leaked from the hydraulic motor.

The present disclosure relates to a lubricating system for lubricating an implement to be lubricated in the boom system of a working machine, the system comprising a lubricant source which can be installed in a base machine for the working machine and coupled to the implement to be lubricated. The lubricating system further comprises a dispensing unit which can be connected to the implement to be lubricated, for dispensing lubricant to the implement to be lubricated. The present disclosure also relates to a working machine comprising a lubricating system.

A linear motion guide system is disclosed in which a clearance between a slider and a guide rail is closed truly to clear foreign matter away from entering inside the system through any end of the slider traveling on the guide rail. Thus, the linear motion guide system is befitting to severe working environment where much foreign matter occurs. A highly-tight sealing unit is comprised of a cassette constituted with a front panel and an enclosure, sealing plates stowed into the cassette, lubrication plates each interposed between any two adjacent sealing plates, and a rear panel to close-an open edge of the enclosure. The sealing plates are each composed of an intermediate spongy medium flanked by skin layers and impregnated with lubricant. The lubrication plates have pores filled with lubricant.

A lubricant device of four-stroke engine is provided according to the present invention. The lubricant device is applicable to a four-stroke engine having a cylinder, a crank case, a rocker arm room and a cam room connected to the rocker arm room. The lubricant device mainly has the rocker arm room and the crank case be connected to each other, and the design of alternating oil supply and oil recycling channels enables lubricant mists to cycle from the crank case through the rocker arm room to the cam room and then be re-absorbed into the crank case, thereby allowing engines to be manipulated at various angles.

A separator for a bearing comprising a frame including a plurality of cavities for receiving rolling elements and further including a lubrication channel in fluid communication with at least one of the plurality of cavities. This separator may be a component of a bearing including an inner race, an outer race, and a plurality of rolling elements disposed in each of the plurality of cavities of the separator and set to be in movable contact with the outer race and inner race of the bearing. A lubricant is introduced into the lubrication channel and flows into each of the plurality of cavities which provides evenly distributed lubrication to each rolling element of the bearing assembly.
