Miniature lubricating assembly

Abstract

A miniature lubricating assembly is formed by coupling at least two units together in an axially abutting manner. Each unit has two connection portions on two opposite ends and a mounting portion on a largest outer peripheral surface. The connection portions between two adjacent units form a pair of interfaces with complementary shapes so as to couple tightly with each other. The mounting portion is securely encased in an inner wall surface of a chamber located at each end of a motor housing. At least one groove and a plurality of notches formed on at least one of the connection portions between the two adjacent units. The notches communicate with the groove and an axle hole. In the assembly, the groove forms at least one storage chamber to store lubricating media, and the notches form at least one set of passages communicating with the storage chamber and an axial hole.

Description

technical field [0001] The invention relates to a miniature lubricating assembly, in particular to a lubricating assembly suitable for a fine shaft core rotating at high speed. Background technique [0002] Due to the strict limitation of space, the existing micro bearings used for micro shaft cores may be damaged by the lubricating medium (lubricating medium) after a short period of operation in severe operating environments such as high temperature, low temperature, high load, high speed, and high vibration. media) is gradually exhausted, resulting in high-frequency percussion and collision between the shaft core and the shaft hole wall, resulting in excessive wear and heat, which will eventually lead to noise, shaft scraping, reaming, shaft jamming, etc. Accelerated damage due to abnormal phenomena such as increased power consumption is a technical problem urgently needed to be solved for this type of existing tiny bearings. [0003] In order to form a tribology interfac...

Problems solved by technology

[0009] However, the above-mentioned existing bearings have no recovery mechanism for dynamic pressure and lubricating medium, lack of adjustability to the flow path of lubricating medium and the position and capacity of the storage chamber, lack of flexibility in using multiple lubricating medium, and the complex structure reduces the Miniaturized applicability and mass production, and it increases the cost and is not conducive to heat dissipation; therefore, it has its limitations in applying it to micro-lubrication components and severe operating conditions such as high temperature, low temperature, and high speed. Under load and high vibration operating conditions, the overall structural strength of miniaturized applications is more important
