Embodiment 2

[0057] Embodiment 2 of the injection lubrication system between rolling bearing rings in the present invention: the difference between this embodiment and embodiment 1 is that the nozzle in this embodiment only has a nozzle, and one end of the nozzle shrinks to form a nozzle, and the other port is connected to the pump The source is connected, and the middle part of the nozzle is hinged on the lifting screw rod through a hinge shaft, and the rotation axis of the hinge shaft is perpendicular to the rotation axis of the lifting screw rod itself. At this time, the rotation axis of the hinge shaft is the first rotation axis, and the pushing structure of the nozzle mounting part is fixed on the hinge seat, so that the nozzle mounting part can rotate around the second rotation axis together with the nozzle, and the action output end of the nozzle mounting part Cooperate with the ejection of the nozzle, and set the corresponding elastic reset structure between the nozzle and the lifti...

Embodiment 3

[0058] Embodiment 3 of the injection lubrication system between rolling bearing rings in the present invention: the difference between this embodiment and Embodiment 1 is that in this embodiment, the first angle adjustment mechanism and the second angle adjustment mechanism are the first drive motor and the second angle adjustment mechanism respectively. For the second drive motor, the axis of the output shaft of the first drive motor is the first axis of rotation, and the axis of the output shaft of the second drive motor is the second axis of rotation. Wherein, the lifting screw is fixedly installed on the output shaft of the first driving motor, the axis of the lifting screw is perpendicular to the axis of the output shaft of the first driving motor, and the rotation of the output shaft of the first driving motor realizes the swing of the nozzle around the first rotation axis ; The first drive motor is fixed on the output shaft of the second drive motor through the fixing se...

Embodiment 4

[0059] Embodiment 4 of the injection lubrication system between rolling bearing rings in the present invention: The difference between this embodiment and Embodiment 1 is that the lifting screw is replaced by a telescopic rod that can expand and contract along its own axis, and the spray head is directly fixed on the top of the telescopic rod. The radial position adjustment of the nozzle is realized through the extension and contraction of the telescopic rod.

Abstract

The invention provides a rolling bearing inter-ring jet lubrication system. The system comprises a rolling bearing, the rolling bearing comprises a movable circle, a fixed circle and a rolling body arranged between the movable circle and the fixed circle, a jet lubrication device used for lubricating oil jet between rings of the movable circle and the fixed circle and arranged on the axial side ofthe rolling bearing is further included, an oil guide groove is formed in the inner wall of the axial end, facing the jet lubrication device, of the movable circle, the two ends of the oil guide groove extend to the axial end face of the rolling bearing and the rolling body correspondingly, the jet lubrication device comprises a nozzle formed in the axial side of the rolling bearing, and furthercomprises an angle adjusting mechanism used for adjusting the angle so as to enable the jet lubrication device to be aligned with the oil guide groove, a monitoring instrument used for monitoring therotating speed, the lubricating oil viscosity and the density pressure of the rolling bearing and a controller, and the controller controls the angle adjusting mechanism to act according to the signalof the monitoring instrument. The technical problem that in the prior art, the bearing inter-ring jet lubrication system cannot carry out jet lubrication on the rolling bearing at the high rotating speed is solved.

Description

technical field [0001] The invention relates to the field of bearing jet lubrication, in particular to a jet lubrication system between rolling bearing rings. Background technique [0002] Rolling bearings are key components in the transmission, and their working performance has an important impact on the transmission stability and reliability of the entire transmission. Therefore, the rolling bearings must be lubricated to reduce friction and wear inside the bearings and to dissipate heat. However, with the development of equipment manufacturing technology, especially in the fields of aero-engines, high-speed railways and high-precision machine tools, the rotational speed of rolling bearings has become higher and higher, making the DN value of rolling bearings (that is, the limit speed of rolling bearings, determined by bearing The sum of the inner diameter and outer diameter of the bearing is divided by two and then multiplied by the bearing speed) is getting higher and hi...
