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) a rotating nozzle 12 is arranged on one axial side of the rolling bearing 11, the axis of rotation of the nozzle 12 is perpendicular to the axis of rotation of the rolling bearing 11 and the spout of the nozzle 12 is directed towards 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...

Abstract

The invention relates to a method and device for spray lubrication between rolling bearing rings. The method and device for spray lubrication between rolling bearing rings include the following steps: 1) Rotate and install a nozzle on one axial side of the rolling bearing, the rotation axis of the nozzle is perpendicular to the rotation axis of the rolling bearing and the nozzle The nozzle of the nozzle faces between the inner ring of the rolling bearing and the cage; 2) Connect the oil pump to the nozzle and set the injection pressure and injection speed of the nozzle; 3) The transmission connection on the nozzle is used to drive the nozzle to swing to adjust the incident angle of lubricating oil The driving device monitors the rotational speed of the rolling bearing through the rotational speed sensor and transmits the rotational speed signal of the rolling bearing to a controller. The ratio coefficient between the incident angle of lubricating oil and the DN of the rolling bearing is preset in the controller. The proportional coefficient between the angle and the rolling bearing DN is used to control the driving device to drive the nozzle to swing to the corresponding lubricating oil incident angle; it can control the amount of oil injected into the rolling bearing.

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...
