THE EFFECT OF SURFACE TEXTURING ON THE FRICTIONAL RESISTANCE OF STEEL-BRONZE ASSEMBLY IN LUBRICATED SLIDING
Journal Title: Tribologia - Year 2018, Vol 279, Issue 3
Abstract
The experiments were carried out using a block-on-ring tester. The block samples made from bronze CuSn10P of 138 HB hardness were burnished to obtain surfaces with circular oil pockets. Rings were made from 42CrMo4 steel of hardness 40 HRC. Friction tests were conducted at a constant normal load of 900 N. Tests were carried out at increasing sliding speeds of the range 0.08 – 0.82 m/s, starting from the lowest speed. The every speed was maintained for two minutes. The tested assembly was inserted in the reservoir of mineral oil L-AN 46. It was found that the dimple presence on block surface reduced the friction coefficient substantially compared to non-textured turned surfaces. The area density of dimples smaller than 15% (particularly 4.5% and 6%) was beneficial.<br/><br/>

EFFECTS OF THE APPLICATION OF LOW-FRICTION COATINGS IN THE GEAR OF A CHAIN CONVEYOR
There are many problems in the operation of spiral bevel gears; for example, difficult lubrication conditions lead to excessively high oil temperature and the risk of severe wear. Thus, the aim of this work was to check...
