Embodiment Construction

[0011] Such as figure 1 , 2 As shown, a quick scraping and repairing method for the lining tile surface of a Babbitt alloy bearing includes the following steps: Step 1, lightly poke 6-10 times on the bearing lining tile surface 1 with the tip of a triangular scraper to make the bearing lining tile surface Corresponding micro-protrusions 2 appear, and a row of micro-protrusions 2 is axially arranged at the bottom of the bearing lining surface 1, and 1-2 rows are arranged on both sides of the row in the axial direction according to the specifications of the bearing lining, and each row of micro-protrusions 2 There are 2-3; step 2, after grinding the hollow shaft 3 and the bearing lining tile surface 1, scrape according to the change of the micro-protrusion 2, the scraping volume of the micro-protrusion 2 is greater than that of the micro-protrusion 2 when it is ground or low on the tile surface 2 The scraping sales volume at the higher tile surface; the scraping sales volume de...

Abstract

The invention provides a rapid scraping repair method of a babbitt metal bearing bushing surface. The rapid scraping repair method of the babbitt metal bearing bushing surface comprises the following steps of 1, slightly pricking the bearing bushing surface for 6-10 times through a point of a triangular scraper to enable corresponding tiny protrusions to appear on the bearing bushing surface; 2, mutually grinding a hollow shaft and the bearing bushing surface, and performing scraping according to changes of the tiny protrusions, wherein scraping quantity of the bushing surface with flat or low tiny protrusions is greater than that of the bushing surface with high tiny protrusions. By means of the rapid scraping repair method, grinding and scraping times are reduced, scraping repair time is greatly shortened, scraping time is shortened to one to third of the existing scraping time, workload is reduced, stopping times is reduced to the greatest extent, and production efficiency is increased.

Description

technical field [0001] The invention belongs to the field of processing and repairing of bearing linings of large and medium-sized bearings, and relates to a method for quickly scraping and repairing the lining surface of Babbitt alloy bearings. Background technique [0002] The bearing lining used in the ball mill is Babbitt alloy. The matching between the shaft and the Babbitt alloy tile surface requires high precision. When a fault occurs, it is difficult to repair and the repair period is long. Due to the low melting point of Babbitt alloy, the normal operating temperature does not exceed 100°C. Therefore, failures are prone to occur. The traditional working method is to scrape the pins according to the imprint left by the two parts of the hollow shaft and the bearing bush after they are grinded together. Since it is difficult to grasp the actual situation of the tile surface, it can only be repeatedly ground and scraped. The work progress is very slow. Slow, it takes mo...
