Abstract

The utility model is related to a kind of independent sealed bearing arrangements, including bearing outer ring, bearing inner race and the roller and retainer being installed between bearing outer ring and bearing inner race；The both ends of the bearing outer ring and bearing inner race extend outwardly respectively, it is respectively formed with preceding seal chamber and rear seal chamber in the both ends of roller, it is separately installed with Front oil seal and Rear oil seal in the preceding seal chamber and rear seal chamber, the sealing space of roller is collectively formed between the bearing outer ring, bearing inner race, Front oil seal and Rear oil seal；The utility model has carried out structure optimization to traditional bearing arrangement, in forming safe and reliable sealing space in bearing, ensure that lubricating oil or lubricating grease can improve performance and the service life of bearing with parts such as sufficient lubrication bearing rollers.

Description

A kind of independent sealed bearing arrangement

Technical field

The utility model is related to field of bearings, especially a kind of independent sealed bearing arrangement.

Background technology

Currently, bearing reliability operation realizes that lubrication, protection bearing are normal by lubricating oil or lubricating grease substantially in the market Work.The oil sealing that existing bearing lubrication must have the cavity of external cooperation and coordinate with cavity realizes sealed environment, due to outer Larger in the space of sealing, the demand dosage of lubricating oil or lubricating grease is also more, and cavity has casting generally by casting and forming Defect can then lead to poorly sealed hidden danger, and since cavity span is larger, if the coaxiality error at the left and right both ends of bearing is big Also result in poorly sealed hidden danger；It frequently results in lubricating oil or lubricating grease is lost in, cause bearing to generate dry friction, influence bearing Support and guiding function.

Utility model content

The purpose of this utility model is to provide a kind of independent sealed bearing arrangements to realize bearing by structure optimization The safe and reliable small sealing space of interior roller, ensures lubricating oil or lubricating grease sufficient lubrication bearing roller, improves the use of bearing Performance and service life.

To solve the above problems, the utility model uses following technical scheme：

A kind of independent sealed bearing arrangement, including bearing outer ring, bearing inner race and it is installed on bearing outer ring and bearing Roller between inner ring and retainer；The both ends of the bearing outer ring and bearing inner race extend outwardly respectively, in the both ends of roller It is respectively formed with preceding seal chamber and rear seal chamber, Front oil seal and rear oil are separately installed in the preceding seal chamber and rear seal chamber Envelope, is collectively formed the sealing space of roller between the bearing outer ring, bearing inner race, Front oil seal and Rear oil seal.

Specifically, the Front oil seal and Rear oil seal are TC outside framework oil seals.

The beneficial effects of the utility model are：Design is optimized to existing bearing arrangement in the utility model, by axis The both ends held extend the sealed chamber to form to install oil sealing, and the sealing space of roller so can be just formed in bearing, Coordinate without external cavity；One side technological operation is simpler, relatively smaller, the required profit in the space on the other hand constituted Lubricating oil or fat dosage can be less, ensure that the sufficient lubrication of the components such as sealing effect and bearing roller, improve making for bearing With performance and service life.The utility model it is compact-sized, technique realize difficulty it is smaller, can match high requirement use ring In border.

Description of the drawings

Specific embodiment of the present utility model is described further below in conjunction with the accompanying drawings, wherein：

Fig. 1 is the structural schematic diagram of the utility model.

Specific implementation mode

With reference to a kind of attached independent sealed bearing arrangement shown in FIG. 1, including bearing outer ring 1, bearing inner race 3 and peace Loaded on the roller 4 and retainer 5 between bearing outer ring 1 and bearing inner race 3.

The both ends of the bearing outer ring 1 and bearing inner race 3 extend outwardly respectively, before the both ends of roller 4 are respectively formed with Seal chamber 7 and rear seal chamber 8 are separately installed with Front oil seal 2 and Rear oil seal 6, preceding oil in the preceding seal chamber 7 and rear seal chamber 8 Envelope 2 and Rear oil seal 6 are TC outside framework oil seals.It is collectively formed between the bearing outer ring 1, bearing inner race 3, Front oil seal 2 and Rear oil seal 6 The sealing space 9 of roller 4.

Lubricating oil or lubricating grease are interior to 4 sufficient lubrication of roller in sealing space 9, and are not susceptible to be lost in, and ensure that bearing Performance.

The preferable specific implementation mode of the above, only the utility model, but scope of protection of the utility model is not limited to In this, any one skilled in the art is in the technical scope that the utility model discloses, the change that can readily occur in Change or replace, should be covered within the scope of the utility model.Therefore scope of protection of the utility model is with claim Subject to the protection domain of book.
