The depth and width of the oil groove of the oil groove copper bushings have an important impact on the lubrication performance, as follows:

The effect of oil groove depth:

Advantages:

Store more lubricant: deeper oil grooves can store more lubricant, in the initial operation of the equipment or a long time after the re-start, can provide sufficient lubricant for the friction surface, to avoid dry friction, effectively reducing wear and prolonging the service life of the copper sleeve and related components. For example, in some large heavy machinery, the reasonable design of the depth of the oil tank can ensure good lubrication of the equipment under high load and long time operation.

Enhance the circulation of lubricant: The increased depth can make the lubricant form a certain pressure difference in the oil groove, which promotes the flow and circulation of lubricant in the oil groove. This circulation helps to take away the heat generated on the friction surface in time, reduce the temperature of the friction part, prevent the deformation of the copper bushing and the decline of lubricant performance caused by overheating, and maintain good lubrication effect.

Disadvantages:

Affect the strength of the copper bushing: the oil groove is too deep will weaken the structural strength of the copper bushing, so that the copper sleeve is more prone to deformation or damage when it is subjected to larger loads. Especially in some high stress, high impact working environment, the oil groove depth is too large may reduce the reliability and service life of the copper bushing.

Increase the processing difficulty and cost: processing deeper oil groove requires higher technical requirements and more complex processing technology, which will increase the production difficulty and cost of copper bushings. Moreover, if the machining accuracy is not up to standard, the uneven depth of the oil groove may lead to uneven distribution of lubricant, affecting the lubrication performance.

Influence of oil groove width:

Advantages:

Improvement of lubricant supply efficiency: wider oil grooves allow more lubricant to enter the friction surface quickly, increase the supply of lubricant, and form a thicker oil film, thus improving lubrication. In high-speed rotation or high load conditions, the wide oil groove can provide enough lubricant for the copper sleeve in time to reduce friction and wear.

Convenient for impurity discharge: wide oil groove can hold more impurities and wear particles, and under the action of lubricating oil flow, it is easier to discharge these impurities out of the copper bushing, reduce impurities on the friction surface of the scratch and wear, and maintain the good working condition of the copper bushing.

Disadvantages:

Reduce the bearing capacity of the copper bushing: The increase in the width of the oil groove will reduce the contact area between the copper bushing and the shaft, thus reducing the bearing capacity of the copper bushing. Under high load conditions, it may lead to deformation or damage of the copper bushing, affecting the normal operation of the equipment.

Affecting the uniformity of lubricant distribution: If the width of the oil groove is too large, the distribution of lubricant in the oil groove may become uneven, resulting in too much lubricant in some areas and not enough lubricant in some areas. This will affect the overall lubrication performance of the copper sleeve, so that the wear of the copper sleeve is not uniform.

In summary, the oil groove depth and width of the oil groove copper bushings need to be reasonably designed according to the specific conditions of use and requirements, in order to achieve the best lubrication performance and service life.
