The groove of the oil groove copper sleeve has various forms, each with its own characteristics and functions, as follows:

Spiral groove:

Characteristics: spiral around the inner or outer wall of the copper sleeve. The pitch and depth of this groove will be designed according to the specific requirements of use.

Role: When the shaft rotates in the copper sleeve, the spiral groove can make the lubricant flow along the spiral direction, forming a good oil film, thus effectively reducing the friction and wear between the shaft and the copper sleeve. Spiral grooves can also increase the storage capacity of the lubricant, extend the use of lubricant time, improve the lubrication effect. For example, in some high-speed rotating mechanical components, spiral groove copper sleeve can provide stable lubrication for the shaft to ensure the normal operation of machinery.

Circular groove:

Characteristics: It is a closed annular groove formed in the circumferential direction of the copper sleeve. The ring groove can be single or multiple parallel distribution.

Role: mainly used to store lubricant, when the shaft and the copper sleeve relative movement, the ring groove lubricant can be evenly distributed to the contact surface, play a lubricating effect. The design of multiple ring grooves can increase the storage and distribution area of lubricant and improve the uniformity of lubrication. For example, in some low-speed, heavy-duty mechanical devices, ring groove copper bushings can withstand greater pressure, while ensuring good lubrication.

Linear shaped grooves:

Characteristics: Distributed in a straight line along the axial or radial direction of the copper bushing. The length, width and depth of the linear grooves are adapted to the specific application.

Function: Straight grooves can guide the flow direction of the lubricant, so that the lubricant can quickly reach the parts that need lubrication. In some special mechanical structures, such as linear motion guide rails or piston devices, linear groove copper bushings can provide good lubrication and support for the linear motion of components.

Mesh groove:

Characteristics: by a number of grooves in different directions are interconnected to form a mesh-like structure.

Role: this groove form can make the lubricant in the copper bushing more evenly distributed, increase the lubricant coverage area, improve the lubrication effect. Mesh grooves can also enhance the heat dissipation ability of the copper sleeve, because the lubricant in the flow process can take away the heat generated by friction. For example, in some high-load, high-temperature working environment, mesh groove copper bushing can effectively reduce the temperature, reduce the thermal deformation of the copper bushing and shaft, and improve the reliability and service life of the machinery.
