Description

Technical Field

[0001] This utility model relates to the technical field of connecting rod small end bearings for piston compressors, and particularly to connecting rod small end bearings for piston compressors. Background Technology

[0002] The connecting rod small end bearing is a key component in a reciprocating compressor. It connects to the small end of the fixed rod and is supported by a bearing to ensure that the reciprocating motion of the piston can be smoothly transmitted to the crankshaft. The connecting rod small end bearing is usually made of wear-resistant materials, such as copper alloy, to withstand high pressure and the heat generated by friction. During the operation of the compressor, the connecting rod small end bearing requires good lubrication to prevent wear and overheating.

[0003] In traditional reciprocating compressors, the connecting rod small end bearing is prone to wear and damage during reciprocating motion due to the difficulty in adding lubricant, which increases friction between the connecting rod small end bearing and the piston pin. This leads to frequent replacements of the connecting rod small end bearing, reducing worker efficiency and increasing workload. Furthermore, excessively worn connecting rod small end bearings may break, posing a potential risk to workers.

[0004] Therefore, regarding the connecting rod small end bearing in the traditional piston compressor, during reciprocating motion, the difficulty in adding lubricant increases the friction between the connecting rod small end bearing and the piston pin, leading to wear and damage. A design can be made that stores lubricant and adds it during operation via the movement of a fixed rod. This lubricant reduces friction, prevents excessive wear of the connecting rod small end bearing, extends its service life, and reduces the frequency of bearing replacement. This decreases the number of replacements required, maintains worker efficiency, reduces workload, and prevents excessive wear leading to bearing breakage and potential safety risks. Utility Model Content

[0005] In order to overcome the problem that in traditional piston compressors, the connecting rod small end bearing is prone to wear and damage during reciprocating motion due to the difficulty in adding lubricant, which increases the friction between the connecting rod small end bearing and the piston pin.

[0006] The technical solution of this utility model is as follows: a connecting rod small end bearing of a piston compressor, comprising a rotating shaft, a mounting assembly, a fixing assembly, a piston assembly, a pressure plate, a fixing column, a spring, a thin tube, a pressure block, a through hole, an oil storage tank, and a fixing rod; a mounting assembly for mounting is provided on the outside of the rotating shaft, a fixing assembly for fixing is provided on one side of the rotating shaft, a piston assembly for pushing is provided above the rotating shaft, a fixing rod is provided above the rotating shaft, an oil storage tank is provided inside the fixing rod, a thin tube is provided at the upper end of the oil storage tank, a pressure block is provided inside the oil storage tank, a fixing column is provided at the upper end of the pressure block, a pressure plate is provided at the upper end of the fixing column, a spring is provided at the upper end of the pressure block, and a through hole is provided at the upper end of the pressure block, the through hole penetrating the pressure block.

[0007] Preferably, the mounting components facilitate installation, the fixing components prevent the fixing rod from falling off, and the piston assembly enables the compressor to operate through reciprocating motion. The movement of the fixing rod causes the small end bearing to exert downward pressure on the pressure plate, which in turn drives the fixing column, which in turn drives the pressure block. The pressure block compresses the internal space of the oil reservoir, storing lubricating oil. A through-hole allows the lubricating oil to pass through the pressure block, and a thin tube guides the lubricating oil to the small end bearing. A spring resets the pressure block, and the movement of the fixing rod adds lubricating oil, preventing excessive wear of the connecting rod small end bearing, extending its service life, and reducing the frequency of replacement. This reduces the number of times workers need to replace the connecting rod small end bearing, maintains worker efficiency, reduces workload, and prevents potential risks to workers due to excessive wear causing the connecting rod small end bearing to break.

[0008] Preferably, the mounting assembly includes a lower cover and an upper cover; the upper cover is provided at the upper end of the rotating shaft, and the lower cover is provided at the lower end of the rotating shaft.

[0009] Preferably, the mounting components also include a base; the upper half of the cover has a base at the top, and the base is located at the lower end of the fixing rod.

[0010] Preferably, the fixing component includes a screw hole, a screw, and a fixing block; a fixing block is provided on one side of the upper half cover, and multiple sets of fixing blocks are provided, with some fixing blocks located on one side of the lower half cover. A screw hole is provided at the upper end of the fixing block, and a screw is provided inside the screw hole.

[0011] Preferably, the fixing component also includes a nut; the nut is provided on the outside of the screw and is located at the lower end of the fixing block.

[0012] Preferably, the piston assembly includes a piston body, a piston pin, and piston rings; the piston body is located above the fixed rod, the piston rings are located on the outer side of the piston body, and the piston pin is located on the inner side of the piston body, with the piston pin penetrating the fixed rod.

[0013] Preferably, an oil inlet is provided on one side of the fixing rod, and a sealing cap is provided on the outside of the oil inlet, which is fixed by threads.

[0014] The beneficial effects of this utility model are:

[0015] 1. The movement of the fixed rod causes the small end bearing to exert downward pressure on the pressure plate. The movement of the pressure plate drives the movement of the fixed column, which in turn drives the movement of the pressure block. The movement of the pressure block compresses the internal space of the oil storage tank, which stores lubricating oil. The lubricating oil passes through the pressure block via a through hole and is guided to the small end bearing through a thin tube. The pressure block is reset by a spring. The movement of the fixed rod adds lubricating oil, preventing excessive wear of the connecting rod small end bearing and ensuring its service life. This reduces the frequency of connecting rod small end bearing replacements, thus reducing the number of times workers need to replace them, maintaining work efficiency, reducing workload, and preventing potential risks to workers due to breakage caused by excessive wear.
