Abstract

The invention discloses a coaxial self-lubricating device for a vertical transmission mechanism. The coaxial self-lubricating device comprises a pump shell (1), and a cylindrical eccentric containingcavity (2) is formed in the lower end of the pump shell (1); a rotor (3) is arranged in the cylindrical eccentric containing cavity (2), and the bottom end of the rotor (3) is rotationally connected with a pump cover (5) through a bearing (4); the part, located in the cylindrical eccentric containing cavity (2), of the rotor (3) is provided with a blade groove (6), and a pair of blades (7) is arranged in the blade groove (6); and the blades (7) are in sliding connection with the blade grooves (6). According to the device, oil can be pumped during forward and reverse rotation; the working rotating speed range is wide, and the coaxial self-lubricating device is suitable for lubricating low-speed, high-speed and rotating-speed-adjustable transmission devices; and the displacement of the lubricating device can be set through adjusting the eccentric distance of the cylindrical eccentric containing cavity or the axial height of the cylindrical eccentric containing cavity. The coaxial self-lubricating device can synchronously work along with the transmission mechanism without extra power.

Description

technical field

[0001] The invention relates to a coaxial self-lubricating device for a vertical transmission mechanism, which belongs to the technical field of mechanical transmission lubrication. Background technique

[0002] The existing gear transmission lubrication methods mainly include oil bath lubrication, circulating oil injection lubrication, oil mist lubrication, centrifugal lubrication and so on. Among them, oil bath lubrication and centrifugal lubrication require gears to have high working speed and oil immersion depth, which are not suitable for transmission devices with low speed and certain height difference, and the application occasions are limited. Oil injection lubrication and oil mist lubrication require additional configuration of lubrication circulation device and its power source, high manufacturing cost, complex pipeline layout, and large transmission device. Therefore there are still deficiencies in the prior art and need to be further improved. ...
