Babbit — an antifriction alloys based on lead or tin, low melting point, used to fill between the friction parts of the mobile nodes. Lagerbuchse antimony, copper, zinc, aluminium and other components. The sliding properties of the alloy gives a special heterogeneous structure — bearing solid granules are enclosed in a soft tin or lead based. This reduces the friction and wear of the contacting parts to a minimum, while the rotating parts quickly work to each other. Lead babbit grades: B-88, B-83, B-16, bn are supplied in the form of ingots.
Babbit is very malleable at normal temperatures. They have an extremely low coefficient of friction, They remarkably reduce the wear of friction parts, increase the efficiency of the equipment. Brand B16, B83 include in lead-based solid grains, which relies on the rotating shaft. Fusible base has t° melting point not higher than 320 °C, retains sufficient plasticity to 100 °C. the Maximum speed is 60 km/h. Maximum load: static — 150 kgf/cm2, dynamic — 500 kgf/cm2 sec. Maximum operating temperature: +110°C. the performance of the bearings determines the thickness of the babbit layer on a steel liner. The optimum thickness of fill ≥1 mm. Babbit is able to retain lubricants, while firm enough to serve as a support shaft. The friction coefficient B-16 without lubrication of 0.25, with lubricant — 0,006. This reduces the wear of the shaft.
Mechanical quality B16
At room temperature — increased brittleness when shock and vibration alloy crack and crumble.
Manufacturer of babbit alloy in the form of standardized ingots GOST 1209−90 Composition includes antimony and tin in an amount up to 1/6 by weight of the alloy
Temperature resistance and excellent sliding qualities allow to use a lead babbit at high loads in the engine-thrust nodes of the railway rolling stock, ships, rolling mills, etc. equipment of heavy engineering. Lead babbits relevant to improve the operation of turbine machinery (steam and water turbines), ramovic, crackopening, crank bearings, diesel engines, bearings, crushers, ball and tube mills. Used to fill bearings, marine and stationary steam engines ≤1200 HP, compressors, ≤ 500 HP, hoists ≤1800 HP, electric motors ≤ 270 kW. and generators ≤ 500 kW.
