Problems solved by technology

[0002] In the past, in order to achieve the purpose of prolonging the life of the motor, the oil content of the oil-impregnated bearing was generally selected. For the type of oil-impregnated bearing with a relatively high oil content, the bearing volume will be relatively larger. Although it is helpful to prolong the life of the motor, it will not Volumetric bearings may not be suitable for the small assembly space in the original motor. Even if large-volume bearings can be used, their cost is often relatively high. After all, the amount is limited, and the problem of prolonging the life of the motor has not been fundamentally solved in essence.

Embodiment Construction

[0046] Please refer to figure 1 and figure 2 , the first embodiment of the present invention will be described below. Motor 1 uses the bearing structure of 1 oil-impregnated bearing 2, offers oil storage hole 20a or 20b on one end side or both sides, and the quantity of oil storage hole 20a or 20b can be single respectively (such as figure 2 (a) shown), can also be multiple (such as figure 2 (b) shown). The size and depth of the oil storage hole 20a or 20b can be changed and specifically adjusted according to actual needs, combined with the size and precision requirements of the bearing itself, and other aspects. The oil storage hole of the oil bearing 2 can have various structural changes as follows:

[0047] Such as figure 2 As shown in (a), the oil bearing 2 is provided with a single hole 20a on one side (the hole does not pass through);

[0048] Such as figure 2 As shown in (b), the oil bearing 2 is provided with holes 20a on one side (the holes are not connect...

Abstract

The invention relates to an oil bearing. The oil bearing is characterized in that reserve fuel quantity is enhanced, and oil keeping time is longer, and at least one side end of the oil bearing is at least provided with an oil storage concave part; a port of the oil storage concave part retracts to the most relative to the most outside of the side end of the bearing, and the side end is provided with an oil undertaking wall; the oil undertaking wall is positioned on the periphery of a port of an oil storage hole, and an oil circulation gasket is fixed on a spindle connected with the oil bearing; and the oil circulation gasket is positioned in a distributing region of the oil in the oil storage hole, and the port of the oil storage hole is sealed by a cover part.

Even if large-volume bearings can be used, their cost is often relatively high. The quantity is also limited after all, and the problem of prolonging the life of the motor has not been fundamentally solved in essence. Contents of the invention [0003] The purpose of the present invention is to provide an oil-impregnated bearing, which can obtain the characteristics of enhanced oil storage capacity and longer oil retention time. [0004] The oil-impregnated bearing of...
