Lubrication training (dojo Case analysis) - Type coupling

Lubrication training (dojo Case analysis) - 2019 - type coupling 12 - 27 is introduced: type coupling is one of the portable rigid coupling, it is the use of internal and external toothing for two and a half coupling between the transmission of torque and rotation motion, apply to join the two concentric shaft drive line, a certain compensation performance of the two axes relative displacement. It generally by the inner ring gear, gear shaft sleeve and end cover and other major parts. Features: type coupling radial size, large carrying capacity, often used for shaft transmission of working condition of low speed and heavy loading, high precision and the dynamic balance of coupling can be used for high-speed transmission. Type coupling due to its compact structure, large carrying capacity, wide speed range, reliable use, etc and is widely used in metallurgy and other kinds of machinery industry. Case analysis as a set of production line, and in the coupling of tension roller disassembly check the homework, found that the coupling of the internal and external tooth suffered serious wear and tear. Tooth surface dry, poor lubrication, as shown in the figure below: type coupling wear is the cause of bad lubrication, coupling the lubricating oil reservoir type, oil for 2 # lithium base grease, lubrication cycle for 3 months. Due to the lubricating oil when installation not evenly daub, leading to equipment wear and tear. To eliminate hidden dangers, the coupling for replacement, production line of similar equipment for the screening and found a few type coupling appear different degree of wear and tear. Summary this is a typical because of poor lubrication, lead to equipment wear and tear, although not caused equipment downtime, but the damage is very serious. For this kind of situation, the following measures: a, according to 'give oil standards periodically' fill oil, 3 months for 1 time fill oil; Second, fixed monthly repair, maintenance project check coupling state of lubrication and abrasion of the tooth surface; Three, the dimensional inspection unit come on personnel training, standardize operations. （ Beijing shougang tang tin plating)
