Abstract
Description
Technical Field
[0001] This utility model relates to the field of compressor component technology, and in particular to a high manganese steel oil baffle for an air conditioning compressor. Background Technology
[0002] The oil baffle of a compressor is an important component, mainly used to prevent lubricating oil leakage and ensure the normal operation of the internal lubrication system of the compressor.
[0003] Application No. 202012235667X discloses a compressor oil baffle that saves lubricating oil. By having a groove for storing leaked lubricating oil, it avoids lubricating oil leakage and pollution, effectively reducing lubricating oil consumption and saving resources.
[0004] Setting up slotted storage for oil reduces oil waste, but the oil tends to accumulate in the slots, resulting in poor oil flow and uneven oil distribution. This, in turn, affects the lubrication of the equipment and its normal operation. Utility Model Content
[0005] In view of this, the purpose of this utility model is to propose a high manganese steel oil baffle for an air conditioning compressor to solve the problem of poor oil flow.
[0006] Based on the above objectives, this utility model provides a high-manganese steel oil baffle for an air conditioning compressor, including an oil baffle body. The oil baffle body has a central hole in the middle, and multiple sets of slots are equidistantly arranged around the inner side wall of the central hole. A guide groove is also provided on the inner side wall of the central hole, and the guide groove is located between the slots. Multiple sets of mounting posts are arranged around the oil baffle body, and mounting holes are provided on the mounting posts. A flow hole is provided on the side of the oil baffle body, and an oil baffle boss is provided on the side of the oil baffle body. A groove is provided on the side of the oil baffle boss, and a rubber ring is engaged in the groove.
[0007] A further improvement is that the oil baffle body is annular, with an outer diameter of φ55mm~φ54.5mm and an inner diameter of φ22.35mm~φ21.65mm.
[0008] A further improvement is that the mounting posts are provided in three sets, the outer side of the mounting posts is stepped, the diameter of the mounting holes is φ4.2mm~φ4.8mm, the height of the mounting posts is 7.75mm~7.25mm, and the height of the steps is 2.75mm~2.25mm.
[0009] A further improvement is that the slot is provided in three sets, including a semi-circular slot opened on the inner side wall of the central hole and triangular slots opened on both sides of the semi-circular slot. The triangular slots are connected to the guide slots, and the side walls of the slots are inclined.
[0010] A further improvement is that the flow passage is of the waist-shaped type, and the sidewall of the flow passage is inclined.
[0011] A further improvement is that the slot and the flow hole are interconnected.
[0012] The beneficial effects of this utility model are as follows: by opening slots and flow holes for oil storage, the consumption of lubricating oil is reduced, resources are saved, and pollution caused by oil leakage is reduced; the slots are connected by guide grooves, and the slots and flow holes are connected to facilitate the flow of oil. Through the flow of oil, the heat in the oil is dissipated, reducing the heat accumulation caused by oil accumulation; and the sidewalls of the slots and flow holes are inclined, which facilitates the collection and flow of oil.

[0018] like Figure 1-4 As shown, this embodiment provides a high-manganese steel oil baffle for an air conditioner compressor, including an oil baffle body 1 with a central hole 2 in the middle. The oil baffle body 1 is annular, with an outer diameter of φ55mm~φ54.5mm (specifically φ55mm) and an inner diameter of φ22.35mm~φ21.65mm (specifically φ22mm). The oil baffle body 1 has a manganese content of 16~20%, a weight of 38.5g~32.5g (specifically 35.5g), and a flatness of ≦0.3mm.
[0019] Multiple sets of mounting posts 5 are arranged around the oil baffle body 1. Each mounting post 5 has mounting holes 6 for installation. There are three sets of mounting posts 5 to make the installation more stable. The outer side of the mounting post 5 is stepped. The diameter of the mounting holes 6 is φ4.2mm~φ4.8mm, specifically φ4.5mm. The height of the mounting post 5 is 7.75mm~7.25mm, specifically 7.5mm. The step height is 2.75mm~2.25mm, specifically 2.5mm. The center distance between the holes of the mounting posts 5 is φ32.7mm~φ32.3mm, specifically φ32.5mm.
[0020] Multiple sets of slots 3 are equidistantly arranged around the inner wall of the central hole 2. These slots store oil.
