Abstract

The invention discloses a regulating device and method for the clearance and the contact spot of a thrust bearing. The regulating device comprises a thrust collar, an ahead thrust device, an astern thrust device, a driving device and a measuring device, wherein the thrust collar is arranged inside the thrust bearing; colorant layers are arranged on the front surface and the back surface of the thrust collar; the ahead thrust device is arranged on a first surface in the thrust bearing; the astern thrust device is arranged on a second surface in the thrust bearing; the driving device is used fordriving a transmission shaft to move axially; when the transmission shaft moves forwards, the ahead thrust device is pressed on the front surface of the thrust collar, and when the transmission shaftmoves backwards, the astern thrust device is pressed on the back surface of the thrust collar; and the measuring device is capable of measuring the axial clearance value of the thrust bearing. The axial clearance check and the contact spot check are realized by one device, so that the efficiency is improved, and through grinding, the size of an adjusting pad can be successfully adjusted, so thatthe accuracy is improved.

Description

technical field

[0001] The invention relates to the technical field of bearings, in particular to a device and method for adjusting gaps and contact spots of thrust sliding bearings. Background technique

[0002] As the key equipment of the power system, the marine gearbox can transmit the thrust generated by the propeller to the hull through the thrust sliding bearing of the gearbox, so that the ship can move forward or backward. Thrust sliding bearing, as a bearing that bears axial thrust and restricts the axial movement of the shaft, is an indispensable part in the structure of large marine gearboxes and is widely used. In order to ensure the force balance of the thrust sliding bearing and prevent bearing damage caused by the unbalanced load of the thrust structure of the gearbox, it is necessary to adjust the contact spots and axial clearance of the thrust sliding bearing to ensure the assembly accuracy and application performance of the thrust sliding bearing.
