Problems solved by technology

[0003] However, the oil content of general oil-impregnated bearings on the market is extremely limited, and the oil in the bearings will be easily consumed during the continuous operation of the motor.
In this way, the friction resistance between the bearing and the shaft will increase, which will easily cause excessive noise of the motor, and even the bad reflection of the motor stuck, which will greatly affect the service life of the motor.
Further, even if oil-impregnated bearings with high oil content are used, the oil content is greatly limited, including the influence of material, size and other conditions, so oil-impregnated bearings with high oil content still cannot solve the fundamental problem
In addition, in addition to the relatively high cost of high oil bearings, it is easy to cause waste of cost

Embodiment Construction

[0017] Such as figure 1 As shown, one end of the bearing segment 1 axially protrudes from a first flange 11 , and a second flange 12 axially protrudes from the first flange. The bearing segment 1 has a central hole 10 which runs through the entire bearing segment 1 .

[0018] Such as image 3 As shown, one end of the bearing segment 2 is recessed to form a groove 21 . The bearing segment 2 has a central hole 20 which runs through the entire bearing segment 2 .

[0019] The outer diameter of the first flange 11 is larger than the outer diameter of the second flange 12 . The inner diameter of the groove portion 21 is greater than the outer diameter of the second flange, and is close to or equal to the outer diameter of the first flange 11 . A shaft shoulder 13 is formed at the root of the first flange 11 of the bearing segment 11 due to a sudden change in the outer diameter. The first flange 11 and the second flange 12 form a flange coupling. The groove portion 21 forms a ...

Abstract

The invention relates to a motor, an oil bearing and a manufacturing method thereof. The oil bearing comprises at least two bearing sections, ends of each two corresponding bearing sections are in butt joint, an oil storage cavity is formed between each two butt joint surfaces of each two corresponding bearing sections, each two bearing sections in butt joint are sintered integrally, and accordingly oiliness of the bearing is greatly improved.

Description

technical field [0001] The present invention relates to a motor, an oil impregnated bearing and a method of manufacturing the same. Background technique [0002] Today's market generally adopts an oil bearing structure to achieve the effect of reducing motor noise and prolonging the life of the motor. The bearing material is generally made of metal or resin. Since the oil-impregnated bearing itself has a certain amount of oil inside, the motor must always keep lubrication between the bearing and the shaft during operation, so the amount of oil stored inside the bearing determines the operation effect of the motor to a certain extent, such as reducing the motor noise and prolong motor life, etc. [0003] However, the oil content of general oil-impregnated bearings on the market is extremely limited, and the oil in the bearings will be easily consumed during the continuous operation of the motor. In this way, the friction resistance between the bearing and the shaft will in...
