Embodiment Construction

[0020] Embodiment 1 of the injection lubrication method between rolling bearing rings of the present invention, as figure 1 As shown, the following steps are included: 1) Install a rotating nozzle 12 on one axial side of the rolling bearing 11, make the rotation axis of the nozzle 12 perpendicular to the rotation axis of the rolling bearing 11 and make the nozzle of the nozzle 12 face the inner ring of the rolling bearing 11 and between the cages. In this embodiment, this step is completed in such a way that the outer ring rotates when the rolling bearing 11 works, so an accompanying ring 13 corresponding to the inner ring of the rolling bearing 11 is provided on the axial side of the inner ring of the rolling bearing 11, and the accompanying ring 13 is opposite to the inner ring of the rolling bearing 11. When the inner ring of the rolling bearing 11 is stationary, the nozzle 12 is rotated on one side of the rolling bearing 11 through a base shaft 14 provided on the accompany...

Abstract

The invention relates to a method and device for implementing jet lubrication among rolling bearing rings. The method for implementing jet lubrication among rolling bearing rings comprises the following steps of: 1) rotatablely arranging a nozzle on the axial side of a rolling bearing, wherein the rotational axis of the nozzle is perpendicular to the rotational axis of the rolling bearing, and a mouth of the nozzle faces a position between the inner ring of the rolling bearing and a cage; 2) connecting an oil pump on the nozzle, and setting the oil jet pressure and jet speed of the nozzle; and 3) rotatablely connecting a driving device for driving the nozzle to swing so as to adjust the inward-jet angle of lubricating oil on the nozzle, monitoring the rotating speed of the rolling bearing through a rotating speed sensor, transmitting a rotating speed signal of the rolling bearing to a controller, and presetting a proportion coefficient between the inward-jet angle of the lubricating oil and the DN (nominal diameter) of the rolling bearing in the controller, so that the controller controls the driving device to drive the nozzle to swing to a corresponding inward-jet angle of the lubricating oil according to the signals of the rotating speed sensor and the proportion coefficient between the inward-jet angle of the lubricating oil and the DN of the rolling bearing. According to the invention, the amount of oil jetted to the inside of the rolling bearing can be controlled.

Description

technical field [0001] The invention relates to the technical field of jet lubrication of rolling bearings, in particular to a method and device for jet lubrication between rings of rolling bearings. Background technique [0002] In order to ensure the safe and reliable operation of the rolling bearing, the rolling bearing must be lubricated in order to minimize friction and wear when the rolling bearing is working, and to avoid pitting on the surface of the rolling bearing and causing failure. The lubrication methods of rolling bearings can be divided into two types: grease lubrication and oil lubrication. Compared with grease lubrication, under high temperature and high speed working conditions, oil lubrication is less affected by temperature changes, and the viscosity of the oil ensures that it does not lose its minimum viscosity at the working temperature, so that a sufficient thickness is formed between the raceway and the contact surface of the rolling element lubrica...
