Bearing bush scraping device of large radial sliding journal bearing

Abstract

The invention discloses a bearing bush scraping device of a large radial sliding journal bearing. The surface of a working platform of the bearing bush scraping device is provided with sliding groovesat intervals. Pressing brackets are located at the two ends of the working platform, and the bottoms of the pressing brackets are arranged in the sliding grooves and positioned through locking screws. Pressing plates are arranged on the top surfaces of the pressing brackets, and the inner side surfaces of the pressing plates are provided with long grooves. Saddle-shaped brackets are arranged on the two sides of the middle of the working platform, and through holes are formed in the top surfaces of the saddle brackets at intervals. Guiding rods and threaded rods are arranged on the bottom surface of a lifting block at intervals, and the threaded rods are located between the guiding rods. The guiding rods and the threaded rods penetrate into the through holes of the saddle-shaped brackets correspondingly. A roller frame is arranged on the lifting block through a rotating shaft. A rolling handle and a bush surface pressing groove roller are arranged on the top surface and the bottom surface of the roller frame correspondingly. According to the bearing bush scraping device of the large radial sliding journal bearing, defects of a traditional bearing bush scraping mode are overcome, the scraping quality is ensured, the labor intensity is reduced, the scraping efficiency is improved, normal operation of equipment is ensured, and the bearing bush scraping device adapts to scraping operation of various specifications of bearing bushes.

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,...
