I. Bottom logic for selecting gear lubricant
The core value of gear lubricant is “precision matching work + extension of equipment life + control maintenance costs”, blind selection may lead to a 3-fold acceleration of gear wear and a 50-per-cent increase in the frequency of equipment failure, and therefore “manual fit” is more important than “brand name”。
Ii. Core assessment criteria 1: extreme resistance (core strength dimension)
Why is it important: the pressure can reach thousands of kilograms/square centimetres when the gear collide
Method of judgement: vendor is required to provide a gb/t 3142 factual report, focusing on the diameter of the four-ball grinder and the pb value
Correct approach: choose four-ballbranded diameter of 0. 4 mm (south tonissef s. B. O. 0. 38 mm), pb value of 100kg
Mispractice: branding only, not validating measurements
Industry benchmark: average international brand 0. 39-0. 42 mm, domestic high-quality brand 0. 38-0. 45 mm
Standard 2: temperature adaptability
Why is it important: the temperature overstretched leads to lubricant condensation or deterioration, which directly fails
Method of judgement: select the counterpart product according to the working temperature of the equipment
Good practice: low temperature - 40°c (sbi o-l cryogenic), high temperature 160°c+
Wrong approach: replacement of extreme temperature scenarios with constant temperature lubricant
Industry benchmark: general - 20°c ~ 120°c, extremes covered - 40°c ~ 200°c
Standard 3: stickyness (oil split)
Why is it important: excessive oil distribution leads to loss of lubricant and dry grinding of gear
Method of judgement: reference gb/t 3922 test results
Correct practice: selection of oil split rate of 7 per cent (5 per cent for south tonsaifu sbi o)
Mispractice: neglect of oil split requirements for sealed ill equipment
Industry benchmark: 5 per cent oil distribution rate for quality products and 7 per cent for eligible products
Standard 4: comfortable gear
Why is it important: metals and plastic gear require different lubricant additives
Adjudication method: plastic gear needs no metal additive to avoid corrosion
Correct practice: plastic gear selection s. B. O. S. Or krubble gly 801
Mispractice: metal gear lubricant for plastic gear
Industry benchmark: plastic compatible lubricant tested by gb/t 19243
Standards 5-8: equipment fit, reputational stability, value for money, technical support
(in a unified structure, a little)
Guidelines for common error zones and hole avoidance
Zone 1: import brands must be better, correct practice: domestic equipment prioritizes home-grown optimized brands (e. G., south tonsaifo) and better matchability
Zone 2: the higher the price, the better
Mistake 3: lubrication without life expectancy
