A filling and draining device for filling lubricant into and draining lubricant out of a housing (1), having a lubricant line (2, 21, 22) through which the lubricant passes into the housing (1), during filling, and through which the lubricant passes when the lubricant is drained from the housing (1). The housing (1) has a valve (6) through which the lubricant flows during filling and draining such that, for filling, the valve (6) adopts a first aperture width for the lubricant and, for draining, the valve (6) adopts a second aperture width for the lubricant.

A method and a lubrication system for lubricating a transmission system component. The lubrication system may include a lubrication system reservoir for storing a lubrication liquid; and a distribution system. The distribution system may be configured to refill, with the lubrication liquid, a transmission system reservoir that is configured to lubricate the transmission system component. The refill occurs while the transmission system component and the lubrication system are positioned within a vacuum chamber.

A gearbox filler assembly includes a cylindrical insert attached to an interior of a port disposed within a housing of the gearbox. The cylindrical insert has a first end disposed within the port, a second end extending outward from the port and is configured to receive a detachable filler cap, a retaining lip around at least a portion of a first interior circumference proximate to the first end, and a retaining slot around at least a second interior circumference between the retaining lip and the second end. A retaining ring is detachably coupled within the retaining slot. A cylindrical baffle is detachably retained between the retaining ring and the retaining lip.

A system includes an oil filling device for a transmission, the transmission having a recess. The oil filling device includes a slotted bushing which is provided with an axially uninterrupted recess through which a cone unit projects, the cone unit having an external thread onto which a nut is screwed, on the side of the slotted bushing facing away from the transmission. The cone unit includes a region that widens in the direction of the transmission, and/or a cone region which presses the slotted bushing against the transmission, in particular in the axial region covered by the recess.

A drive apparatus includes a motor; a reduction gear connected to the motor; a differential connected to the reduction gear, for rotating an axle about a differential axis; a housing including a gear housing portion housing the reduction gear and the differential; and an oil housed in the gear housing portion. The differential includes a gear for rotating about the differential axis. An end portion of the gear is lower than the reduction gear, and is configured to soak in the oil. The housing includes an oil drain hole and an oil feed hole for joining an interior of the housing and a space outside of the housing, a first stopper member removably in the oil drain hole, and a second stopper member removably in the oil feed hole. Each of the oil drain hole and the oil feed hole is in a portion of the gear housing portion.

A straddle-type vehicle includes a drive unit used for driving a rear wheel of the straddle-type vehicle, wherein a discharge port that discharges oil in the drive unit is installed on a lower section of the drive unit, and a guide that guides oil to an outside in a vehicle width direction is installed in a vicinity of a lower section of the discharge port.

A pneumatic transmission fluid delivery apparatus for quick and effective transmission fluid replenishment includes a fluid container and a fluid cap to seal and alternatively expose an inner compartment. An air supply channel is coupled to the fluid container and is in fluid communication with an air aperture. An air hose adaptor is coupled to the air supply channel and is in fluid communication with the air supply channel and is configured to receive a compressor hose to pass compressed air through the air aperture into the fluid container. A fluid tube is coupled to the fluid container and is in fluid communication with an output aperture to deliver pressurized transmission fluid stored in the fluid container to a vehicle transmission.

A guard for protecting a drain plug and a ground-facing surface of an axle housing on a machine including a first portion and a second portion. The first portion has a body configured to be mounted to the axle housing to protect at least portion of the ground-facing surface of the axle housing. The body includes an opening configured to allow access to and removal of the drain plug through the opening. The second portion is removably couplable to the first portion. When the second portion is attached to the first portion, the second portion covers the opening to protect the drain plug. When the second portion is removed, the drain plug is accessible and removable to service oil in the axle housing.

A planetary screw includes a main screw having an outer threading and a connecting portion. A nut includes a hole extending through two end faces of the nut. The hole includes an inner periphery having an inner threading. A planetary unit includes a supporting mechanism and a plurality of rollers rotatably supported by the supporting mechanism to rotate in a fixed position. The plurality of rollers is identical to each other. Each of the plurality of rollers has an outer threading meshed with the outer threading of the main screw and the inner threading of the nut. The planetary screw can be used in a machine tool.

A lubricating oil discharge and filling structure of an oil pan including a cylindrical lubricating oil amount adjustment wall vertically provided from a bottom surface of the oil pan, and having a lubricating oil amount adjustment passage communicating with an outside of the oil pan, formed on an inner periphery. The lubricating oil amount adjustment wall has a lubricating oil discharge hole formed in a lower part, to the lubricating oil amount adjustment passage, a cylindrical lubricating oil amount adjustment plug in which a communication hole that communicates with the lubricating oil amount adjustment passage is formed is assembled movably along the lubricating oil amount adjustment passage. The lubricating oil amount adjustment plug includes a screw portion that screws into a screw groove formed in the lubricating oil amount adjustment passage, and a sealing wall that seals discharge of the lubricating oil from the lubricating oil discharge hole.
