Description

Technical Field

[0001] This utility model relates to the field of copper bushing technology, specifically a copper bushing structure with multiple oil inlet channels. Background Technology

[0002] Copper bushings, also known as copper shaft sleeves, come in various types, including machine copper rollers and copper bearings. They are used in various light industrial, large, and heavy machinery, serving as important mechanical components. As bearings, they can be used in compressor bearings. Copper bushings possess high hardness, excellent wear resistance, and are not prone to seizing. They also have good casting and machining properties, and exhibit good corrosion resistance in air and fresh water.

[0003] Traditional copper bushings are generally cylindrical in structure with several oil inlet channels. However, each oil inlet channel requires a separate oil inlet port to connect with the bearing housing shaft, increasing the difficulty of bearing housing machining and complicating oil circuit connections. Currently, there is a type of copper bushing with an annular groove containing several oil inlet channels, allowing the bearing housing to have only one oil inlet port. However, this structure currently typically uses a single annular groove, which results in slow oil flow and low efficiency. Therefore, an improved technology is urgently needed to solve this problem in the existing technology. Utility Model Content

[0019] Please see Figure 1-4 This utility model provides a technical solution: a copper sleeve structure with multiple oil inlet channels, including a copper sleeve body 1. The outer surface of the copper sleeve body 1 is uniformly provided with several annular grooves 2 along the circumferential direction. The outer diameter of the copper sleeve body 1 at each annular groove 2 is the same to ensure that the oil storage volume in each annular groove 2 is the same and there will be no pressure difference. The inner surface of the copper sleeve body 1 is uniformly provided with several oil cavities 3. The inner wall of the copper sleeve body 1 at each oil cavity 3 is recessed outward 7. The recess 7 does not contact the main shaft, so that the lubricating oil enters into the recess 7 and fully contacts the main shaft to improve the lubrication effect. An oil inlet channel 4 is provided between the oil cavity 3 and each annular groove 2. An annular protrusion 5 is formed between adjacent annular grooves 2. The outer diameter of the copper sleeve body 1 at each annular protrusion 5 is the same to ensure that it can be inserted into the bearing seat completely and smoothly. The annular protrusion 5 is provided with several notches 6, and adjacent annular grooves 2 are interconnected through the notches 6. The copper sleeve body 1 is inserted into the bearing housing 8. An oil inlet 9 is provided on one side of the bearing housing 8. The oil inlet 9 corresponds to any one of the annular grooves 2, so as to ensure that the lubricating oil can smoothly enter the corresponding annular groove 2 from the oil inlet 9, and then enter other annular grooves 2 through various notches 6.

[0020] Usage and Operating Principle: First, a copper sleeve body 1 is manufactured. The inner wall of the copper sleeve body 1 has several oil cavities 3. Then, the sleeve is clamped using a machine tool fixture, and an annular groove 2 is created on the surface of the copper sleeve body 1 using a cutting tool. Simultaneously, a notch 6 is created at the corresponding position of the annular protrusion 5, located on the vertical line between two oil cavities 3. Finally, an oil inlet channel 4 is created using a drilling machine, connecting the oil inlet channel 4 to the oil cavities 3, completing the machining process. In use, the sleeve is inserted into the bearing housing 8, with the oil inlet 9 of the bearing housing 8 corresponding to one of the annular grooves 2. Lubricating oil enters from the oil inlet 9 of the bearing housing 8, then flows into the corresponding annular groove 2, and subsequently enters the other annular grooves 2 sequentially through the notch 6. Finally, it enters each oil cavity 3 through the oil inlet channel 4, achieving lubrication of the inner wall of the sleeve and thus lubrication between the sleeve and the spindle. This utility model has a reasonable structure. The outer surface of the copper sleeve body 1 is provided with several annular grooves 2. Adjacent annular grooves 2 are connected to each other through notches 6. Each annular groove 2 is provided with an oil inlet channel 4 to realize synchronous oiling of each oil cavity 3. This structure can realize synchronous and uniform oiling of each oil cavity 3 without increasing the oiling port of the bearing seat 8. The oiling speed is fast and the oiling efficiency is high. At the same time, due to the presence of several annular grooves 2, the amount of copper used is also saved, thereby saving production costs.
