Using Yu sliding bearing within of oil are has rust sexual, rust of performance good or bad main is see oil of soluble, different stick consistency and different material formed of grease, has different level of anti-capacity and rust performance, General of,, stick consistency large and fat dissolved sexual poor of oil waterproof sexual better, such of oil even in culture forest cavity in the full has water, also can in steel surface formed a layer can resist of oil film. Bike due to speed low, oil of select can relative with stick consistency slightly high, but waterproof sexual very strong of type, because bike in wash car, rainy day, cross-country, are often and water deal, this on makes waterproof sexual very important, even is slightly stick heavy of oil, also does not effect low turn Xia of smooth, and once surface formed has oxidation damage, that whole stripping process and aging process are will fast of increased.
Oils in high speed rotation, at times soft, leading to leakage, when when there is vibration, oil will be squeezed from your Raceway thrown oil is producing mechanical disintegration which makes oil SOAP structure is destroyed, or even throw bearing.
Oil seal is contains oil and sliding bearing does not by outside pollution of portal, industrial Shang many bearing only using has ball maintained frame, some using of is metal oil seal system, some because has automatically refueling system, and rendering full open State, and bike usually cannot using such of bearing, otherwise only in oil depletion or pollution of first a cycle Hou, that declared life end, and metal oil seal of sliding bearing while also can in a more long time avoid pollution, and can up to containing oil role, But yihou cannot opened new note oil or for full of clean, so also also does not for bike using, bike using of sliding bearing must select purchased with rubber seal of, this package of anti-pollution performance good, oil maintained time long, and can in a is long of using cycle Hou, will plastic oil seal pick opened, then will internal for full of clean and oil of replaced.
4. mix oil
Never grease mix incompatible, if two incompatible greases mixture, usually soft consistency, final loss damage because fat easily, if you do not know your bearings using grease, you first have to clear all the grease, and then add a grease lubricated.
, Cleaning plain bearings and related parts (already grease-lubricated bearings and double-sided with seals or shields, seal ring bearing before installation no cleaning. ）
, Check the relevant parts of sizes and finishing
And installation method
Installation of sliding bearing should be based on the bearing structure, size and bearing parts fit in nature may be, pressure should be directly added to the tight fit on the ferrule end face, shall not pass through the rolling pressure bearing installation use the following method:
A. press fit
Tight fit sliding bearing inner ring and shaft, when the outer ring and the housing bore is a loose fit, you can first press bearing press mounting on the shaft, and then load the shaft with bearings into the housing bore, when pressure on the bearing inner ring side face, mat made of a soft metal Assembly bushing (copper or mild steel).
Sliding bearing outer ring and the housing bore tight fit, when the inner ring and shaft for a loose fit, you can press the bearing into the housing bore, fitted sleeve outside diameter is slightly smaller than the diameter of the hole should be.
If the bearing ring and shaft and housing bore when you are tight fit, installing the indoor ring and the outer ring also pressed into the shaft and housing bore, assemble the casing structure should be able to simultaneously charge adapter for ball bearing inner ring and outer ring side face.
B. heating combined with
By heating the bearing or housing, use of thermal expansion installation method of the tight fit into a loose fit. Is a popular and labor-saving installation method. This method suitable for bearing installation of larger amounts of interference, charging the former separable bearings or bearing rings into the tank evenly heated 80-100 ℃, and then remove from oil loaded on the shaft, as soon as possible, in order to prevent cooling after the end surface of the inner ring and shaft shoulder fit firmly, after the shaft axial fastening. Bearing outer ring with light metal housings when tight fit, heating the bearing seat and charging method used, you can avoid scratch the mating surfaces.
