Bearing pad scraping device for large radial sliding journal bearings

Abstract

The invention discloses a bearing pad scraping and grinding device for a large radial sliding journal bearing. The surface of the working platform of the device is provided with chute grooves at intervals, the pressing brackets are located at both ends of the working platform, and the bottom is arranged in the chute grooves through locking screws. Positioning, the pressing plate is arranged on the top surface of the pressing bracket and the inner side is provided with a long groove, the saddle-shaped bracket is arranged on both sides of the middle part of the working platform and the top surface is spaced with through holes, and the guide rod and the screw rod are arranged on the bottom surface of the lifting block and The screw is located between the guide rods, the guide rod and the screw are respectively inserted into the through holes of the saddle bracket, the drum frame is set on the lifting block through the rotating shaft, the rolling handle and the tile surface grooved roller are respectively set on the top surface and bottom surface of the drum frame . The device overcomes the defects of the traditional bearing pad scraping and grinding method, ensures the scraping and grinding quality, reduces labor intensity, improves the scraping and grinding efficiency, and ensures the normal operation of the equipment.

Description

technical field [0001] The invention relates to a bearing pad scraping device for a large radial sliding journal bearing. Background technique [0002] Large radial sliding journal bearings are widely used in large rotary machinery, such as large ball mills, rotary kilns, coolers, etc. For this type of bearing with heavy load and low speed, establishing a safe and reliable lubricating oil film is the focus of research in recent years. In the installation project, the scraping of the bearing bush is the key process of the whole mechanical installation project. Many machines have caused major quality or safety accidents due to the scraping of the bearing bush, because the scraping of the bearing bush is different from the individual skills of the operator. difference. Usually, the scraping of bearing pads is done by manual operations such as rough scraping, fine scraping, and slotting. The scraping quality varies from person to person, and it is time-consuming and laborious,...
