Description

Tapered roller bearing with grooved inner ring

Technical Field

The utility model relates to a tapered roller bearing structure specifically relates to an inner circle grooved tapered roller bearing uses in the structure that uses flexible space ring, belongs to bearing technical field.

Background

And a flexible space ring structure is used in part of the system, so that the self-adaptive capacity of the whole system can be improved. The bearing inner ring has high rigidity, so that the bearing inner ring is not easy to break when subjected to impact load, and the flexible space ring has low rigidity and plays a role in buffering when subjected to impact load. If a common bearing inner ring is adopted, a plurality of oil ports are required to be opened on the flexible spacer ring for packaged lubrication to realize oil lubrication. However, the strength of the flexible space ring is greatly reduced in use, and the flexible space ring is easy to break.

Disclosure of Invention

In view of the above technical problem, the utility model discloses a special tapered roller inner circle makes its inner circle trough of belt, when making the bearing inner circle play the location bearing, has packed the function of lubricated hydraulic fluid port.

In order to realize the purpose, the utility model discloses the technical scheme who adopts is: an inner race grooved tapered roller bearing comprising: the roller cage comprises an outer ring, a roller, a retainer and an inner ring; the outer ring and the inner ring are respectively provided with a roller path, and the roller is arranged in the retainer and is arranged between the inner ring and the outer ring through the inner ring roller path and the outer ring roller path; the end part of the inner ring in the same direction as the small end of the roller is connected with a bearing space ring, and a groove is arranged on the bearing inner ring close to the edge of the end part of the bearing space ring and used as a circulating oil port for lubricating the whole bearing;

the bearing space ring is made of flexible materials;

furthermore, an outer flange and an inner flange are arranged on the outer circumference of the bearing inner ring, the roller is arranged between the outer flange and the inner flange of the inner ring and is positioned on one side of the inner flange, and the groove is arranged on the other side of the inner flange of the bearing inner ring;

further, the outer diameter of the bearing inner ring at the position where the groove is formed is the same as the outer diameter of the joint transition part of the bearing space ring;

furthermore, grooves formed in the inner ring of the bearing are uniformly distributed at equal distances along the circumference of the inner ring of the bearing;

furthermore, the number of the grooves is set to be 4, and 90 degrees are set between every two adjacent grooves;

further, the above structure is applied to a double row tapered roller bearing, that is, the grooved inner ring structure is located on both sides of the bearing spacer.

The utility model has the advantages that: by adopting the tapered roller bearing with the inner ring slotted structure, the inner ring of the bearing plays a role in positioning the bearing and simultaneously packages the function of a lubricating oil port. When the structure is used, the lubricating requirement of the bearing can be met while the strength of the flexible space ring can be ensured.

Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that 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 efforts belong to the protection scope of the present invention.

As shown in fig. 1 to 2, an inner race grooved type tapered roller bearing includes: the roller cage comprises an outer ring 1, rollers 2, a retainer 3 and an inner ring 4; the outer ring 1 and the inner ring 4 are respectively provided with a roller path, and the roller 2 is arranged in the retainer 3 and is arranged between the inner ring 4 and the outer ring 1 through the inner and outer ring roller paths; the end part of the inner ring 4 in the same direction as the small end of the roller 2 is connected with a bearing space ring 5, and the edge position of the bearing inner ring 4 close to the end part of the bearing space ring 5 is provided with a groove 6 which is used as a circulating oil port to provide lubrication for the whole bearing;

the bearing space ring 5 is made of flexible materials;

further, an outer flange 4.1 and an inner flange 4.2 are arranged on the outer circumference of the bearing inner ring 4, the roller 2 is arranged between the outer flange 4.1 and the inner flange 4.2 of the inner ring 4 and is positioned at one side of the inner flange 4.2, and the groove 6 is arranged at the other side of the inner flange 4.2 of the bearing inner ring;

further, the outer diameter of the bearing inner ring 4 at the position where the groove 6 is arranged is the same as the outer diameter of the joint transition part of the bearing space ring 5;

furthermore, grooves 6 formed in the bearing inner ring 4 are uniformly distributed at equal distances along the circumference of the bearing inner ring 4;

preferably, the number of the grooves 6 is 4, and 90 degrees are arranged between every two adjacent grooves 6;

further, the above structure is applied to a double row tapered roller bearing, that is, the grooved inner ring 4 structure is located on both sides of the bearing spacer 5.
