Lubrication To extend the life of chain, periodical lubrication is important. However, in the following cases, avoid lubrication. 1) The chain is embedded in the loads (granular material, powder, etc.). 2) Granular material and powder deposit on the chain when carried by pan or apron conveyors. Here, lubrication works adversely. 3) The chain temperature becomes high. ¡Lubricating oils and lubrication frequency SAE SAE30 SAE40 Temperature -10°C ~ 0°C 0°C ~ 40°C In general, lubricate once a week by applying or dripping. ¡Automatic lubrication (oiling) device We have various automatic lubrication (oiling) devices. Consult us if you are using chains in a setup where lubrication is difficult or if you plan to automate lubrication. Service Limits of Conveyor Chain and Sprockets ■ Service limit of conveyor chain Conveyor chain performance gradually deteriorates by wear, corrosion, etc. depending on service conditions. The service limits of respective components are as stated below. ¡R-rollers and F-rollers When the plates begin to contact the rail due to inside and outside wear of rollers. ¡S-rollers and M-rollers When rollers are partially cracked or thickness becomes 40% of the original dimension due to wear. ¡Bushings When the thickness of bushings become 40% of the original dimension due to wear. ¡Plates Service limit of plate thickness : When plate thickness decreases down to 1/3 of the original dimension due to mutual abrasion or contact with rollers. Service limit of plate width : When the plates directly slide on liners, the plates are worn in width, and strength is diminished. In this case, X=1/8B is the service limit. ¡Oblong pin-and bushing-fitted portions. Pins and bushings are securely locked and pressed in plates. Long-term use or an overload loosens the portions where pins and bushings are fitted. In this case, the plate holes become gradually oblong causing sudden progression of chain elongation. This is the service limit. ¡Pitch elongation A chain is bent when it engages with the sprockets or at corners, and the mutual wear between pins and bushings causes the entire length to be elongated. If the elongation becomes excessive, the engagement between the chain and the sprockets becomes less smooth and troubles occur. Limit of chain elongation is 2 % of nominal pitch. Measure chain elongation where tension is applied. Usually, measure from the head of one pin to the head of another, using a tape measure. Measure the length of four pitches or more. ¡Fatigue limit A chain receives varying loads repetitively every cycle. Long-term use causes plates, pins, etc. to reach their fatigue limit, resulting in cracking and then fracture. This is the service limit. ■ Service Limit of Sprocket The wear of sprocket teeth is generally neglected. It is difficult to measure the wear loss and repair by padding is troublesome and diminishes operation efficiency. However, check teeth wear since it promotes wear elongation of the chain. The wear limit is 3~5mm. A sprocket reaching the service limit should be repaired according to a padding gauge or replaced entirely. When a sprocket is replaced, pay attention to hub and key slot dimensions, etc. Wear loss ¡Welding rod for padding In general, select a welding rod of HV350 ~ HV600 in deposited metal hardness from JIS No.DF2B-B according to the degree of wear loss. However, note that if the hardness is about HV600, finishing is difficult. When wear loss is extensive, use welding rod D4316 for underlaying. ¡Teeth gauge for padding Accurate finishing by a grinder using a teeth gauge is necessary when padding. Consult us for gauges.
