Slide block type lubricating device for universal coupling slide block

Abstract

The invention discloses a slide block type lubricating device for a universal coupling slide block. The lubricating device comprises a gearwheel, a sealing cover and a pinion; the exterior of the gearwheel is provided with the sealing cover, and end covers are sealed between the sealing cover and the two end faces of gear teeth of the gearwheel; the pinion is arranged in the cavity of the sealing cover, and end covers are sealed between the two end faces of gear teeth of the pinion and the sealing cover; the sealing cover is provided with an oil inlet; the gear teeth of the gearwheel are divided into two kinds, wherein one kind of gear teeth a are provided with grooves along the circumferential direction, and a plurality of gear teeth are continuous; the other kind of gear teeth b are complete gear teeth, the number of the gear teeth b is continuous two, a radial hole is processed between the teeth roots of the two gear teeth b, the radial hole is communicated with an axial hole of the gear, and the axial hole is communicated with a lubricating point of the slide block through an oil passage pipe fitting; and the plurality of gear teeth a and the two complete gear teeth b are circularly arranged at intervals. The lubricating device overcomes the defects of the conventional lubricating mode, realizes automatic, intermittent and quantitative dry oil injection for the universal coupling slide block, and fulfills the purposes of oil economization and good lubricating state.

Description

Technical field [0001] The invention relates to a lubricating device for a sliding block type universal joint shaft sliding block. Background technique [0002] The lubrication of the slider of the slider type universal joint is more difficult, because the friction surface is connected to the outside, and the lubricating oil is not easy to be stored on the friction surface. Impact, dust, moisture, and high temperature invade the slider and fork boring surface to generate heat and burn easily, especially as the rolling rhythm accelerates and the load increases, the situation will be further deteriorated. The current lubrication methods include manual, dripping, pressure, protective cover, slip ring oil supply and palm end lubrication pump (that is, the main body is a swash plate type axial piston pump). Among them: manual lubrication needs to be stopped, relying on manpower and the effect is poor; drip lubrication is primitive and consumes a lot of oil; pressure lubrication takes...
