Description

Bearing outer sleeve with oiling structure

Technical Field

The utility model relates to a bearing technical field, especially bearing housing with oiling structure.

Background

The bearing is an important part in the modern mechanical equipment, and the main function of the bearing is to support a mechanical rotating body, reduce the friction coefficient in the movement process of the mechanical rotating body and ensure the rotation precision of the mechanical rotating body.

The bearing structure and the motor rotating speed influence, after lubricating oil enters the bearing outer sleeve, only a small amount of lubricating oil enters the bearing, and the lubricating supply amount of the lubricating oil is far less than the required lubricating oil amount of the bearing during high-speed operation, so that the bearing is extremely easy to lack oil, the bearing is abraded, and the production line is stopped.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a bearing overcoat with oiling structure when guaranteeing original function, the unable problem of comprehensive lubricated bearing of grease when having solved high-speed rotation again.

In order to achieve the above purpose, the utility model adopts the technical scheme that:

the utility model provides a bearing coat with oiling structure, including the bearing coat body, bearing coat body cavity sets up, be provided with multichannel ring channel, multichannel on the bearing coat body inner wall the ring channel parallel arrangement, the degree of depth of ring channel is less than the thickness of bearing coat body, be provided with the inlet port on the ring channel, the inlet port extends to the terminal surface of bearing coat body, still be provided with the oil outlet on the bearing coat body inner wall, the oil outlet also extends to the terminal surface of bearing coat body.

Preferably, the end face of the bearing outer sleeve body is further provided with a groove, and the groove is sleeved on the periphery of the bearing outer sleeve body.

Preferably, the groove is a non-closed annular structure.

Because of the application of the technical scheme, compared with the prior art, the utility model has the following advantages:

the utility model discloses a bearing coat with oiling structure, including the bearing coat body, bearing coat body cavity sets up, be provided with the multichannel ring channel on the bearing inner wall, the parallel setting of multichannel ring channel is on the bearing inner wall, all be provided with the oil inlet on every channel ring channel, the oil inlet accesss to the entering that is used for lubricating oil on the terminal surface of bearing coat, lubricating oil can spread each department of ring channel after getting into the ring channel, lubricate each department to the bearing inner wall, along with the entering of lubricating oil in addition, through liquid cooling, can make the temperature decline in the bearing coat, still be provided with the oil outlet on the bearing coat inner wall simultaneously, a spill for lubricating oil in the bearing. The temperature of the bearing can be reduced while the regular filling is carried out, so that the service life is prolonged.

Detailed Description

The technical solution of the present invention will be described clearly and completely with reference to the accompanying drawings, and obviously, the described embodiments are some, but not all embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention. Furthermore, the technical features mentioned in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

Referring to fig. 1, fig. 2 and fig. 3 show, the utility model discloses a bearing coat body 1, bearing coat body 1's inside is the cavity setting, when using, the bearing coat can set up in this hollow structure, hollow structure's cross-section is generally circular, be provided with multichannel ring channel 2 on bearing coat body 1's the inner wall, multichannel ring channel 2 parallel arrangement, ring channel 2 encircles on bearing coat body 1's the inner wall, contact with the bearing coat when using, be provided with at least one inlet port 3 on every ring channel 2, inlet port 3 extends to bearing coat body 1's outer terminal surface always, an oil feed for the bearing coat, can diffuse to each department of ring channel 2 after the lubricating oil that gets into, the lubricating oil that gets into can make on the one hand to diffuse to bearing coat body 1 inner wall, and then get into the bearing coat, realize the comprehensive lubrication of bearing, on the other hand, because the entering of cooling liquid, can realize reducing the purpose of bearing temperature, thereby the life-prolonging.

Still be provided with slot 5 on the terminal surface of bearing outer sleeve body 1, slot 5 is non-closed loop configuration, sets up in the periphery of bearing outer sleeve body 1 for increase heat radiating area, make the bearing outer sleeve heat dissipation more quick, non-confined loop configuration when the bearing outer sleeve installation of being convenient for, can satisfy heat dissipation and refrigerated demand again.

When the bearing outer sleeve is used specifically, the inner wall of the bearing outer sleeve body 1 is also provided with an oil outlet 4 for discharging oil dirt in the bearing. Generally, the diameter of the oil outlet hole 4 is larger than that of the oil inlet hole 3, so that the cleaning is more convenient. After the bearing is placed in the motor, grease enters the bearing outer ring and then enters the bearing raceway, and the problem that the motor is damaged due to failure of the grease is solved.

The above embodiments are only for illustrating the technical concept and features of the present invention, and the purpose thereof is to enable those skilled in the art to understand the contents of the present invention and to implement the present invention, so as not to limit the protection scope of the present invention, and all equivalent changes or modifications made according to the spirit of the present invention should be covered by the protection scope of the present invention.
