Comparison of Several Lubrication Methods for Chains
1) Drip oil lubrication Use the drip oil cup to drip the oil between the two hinge plates. Its refueling volume and period should be sufficient to alert the lubricating oil of the chain link hinges to a stable color. The single-row chain drips about 5 to 20 drops of oil per minute, and drops more at high speeds. It is necessary to prevent the oil droplets from being deflected by the wind. If the oil droplets are in the middle of the chain, they cannot effectively slip the combined area. Lubricant must be directed to the inside of the pin and the appearance of the rafter side plate.
2) Brush lubrication Use a brush or oiler to regularly add oil to the ring joints of the inner and outer chain plates on the loose side of the chain, preferably once every 8 hours. Its refueling volume and period should be sufficient to alert the lubricating oil at the joints of the chain links. In the low-speed category (υ <1m / s), the standard pig hair brush is accepted, while in the high-speed category (υ> 5m / s), nylon brushes are accepted, and in the medium-speed category (υ = 1-5m / s), both Are applicable. However, when the speed is extremely high (υ> 10m / s), it is required to force the oil to be lubricated in order to dissipate the heat and reduce the temperature. The normal temperature should not be higher than 70 ° C.
3) Oil bath or oil pan lubrication When lubricating with an oil bath, the lower side chain determines the oil pool in the Gearbox. The oil level should reach the pitch circle line at the lowest position of the chain. When it is necessary to lubricate with an oil pan, the chain is above the oil level. The oil carried by the oil pan from the oil sump is often guided by an oil tank to allow the oil to settle on the chain. The diameter of the oil pan should be sufficient to produce a rotation speed of 3.3 to 4.5 m / s. When the chain width is greater than 25mm, oil pans should be installed on both sides of the sprocket.
4) Oil injection lubrication Oil injection lubrication is to provide a continuous oil flow to each Transmission Chain. Oil should be added to the inside of the chain link, just aligned with the link of the chain link, and guided to the loose side of the chain along the chain width. Lubricating and non-toxic.
