Carrier Centrifuge Bearing 02XR45003201

1. Advantage：

Materials and technology
High-strength materials: usually use high-quality medium carbon steel or medium carbon alloy steel, such as 40Cr, etc., after tempering treatment, with high strength and good toughness, can withstand the alternating load during the operation of refrigeration compressor, to ensure that it is not easy to deformation or fracture under high pressure and high speed working conditions.
Precision machining technology: The use of advanced processing technology, such as CNC milling, grinding, etc., to ensure that the various parts of the connecting rod high dimensional accuracy, strict tolerance control. Small head hole, big head hole cylindricity, roundness and other errors are very small, can achieve high precision with the piston pin, crankshaft connecting rod journal, reduce wear and vibration.
Structural design
Optimized small head structure: The small head adopts an integral structure with bronze bushing inside. This design not only improves the wear resistance of the small head, but also maintains good lubrication performance in relative motion with the piston pin, reducing friction loss and extending the service life of the parts.
Reasonable rod shape: the rod body is usually "H" shape or "I" shape section, while ensuring sufficient strength and stiffness, reduce the weight of the connecting rod, is conducive to reducing the kinematic inertia force, improve the operating efficiency and stability of the compressor, and this shape can also play a role in strengthening the reinforcement to a certain extent, enhance the deformation resistance of the connecting rod.
Reliable head structure: The head is a split structure, connected by high-strength connecting rod bolts. The thin-wall bearing bush is used between the big head and the crankshaft connecting rod journal, which has good bearing capacity and compliance, and can adapt to pressure changes under different working conditions to ensure reliable power transmission.
Surface treatment
Wear-resistant coating: The surface of the connecting rod is usually copper-plated, tin-plated and other surface treatment, or the use of electroless nickel-phosphorus alloy and other processes to form a layer of wear-resistant and corrosion-resistant coating, which can not only improve the hardness and finish of the connecting rod surface, reduce the coefficient of friction between other components, but also effectively prevent rust in the environment of wet or corrosive media. Improve the service life and reliability of connecting rods.
Lubrication treatment: Special lubrication treatment will be carried out on the surface of the small head bushing and the big head bearing, such as processing oil storage tanks, oil holes, etc., to ensure that during the operation of the compressor, the lubricating oil can be evenly distributed on the friction surface, forming a good oil film, further reducing friction and wear, and improving the working efficiency and stability of the components.
