Abstract
The invention relates to an axial positioning roller bearing. The axial positioning roller bearing comprises an outer ring, an inner ring, a sealing ring and rollers, wherein the inner ring is arranged in the outer ring, and the rollers are arranged between the outer ring and the inner ring; and a sealing ring is arranged between the outer ring and the inner ring and at the outer sides of the rollers. The axial positioning roller bearing is characterized by also comprising a retaining ring, wherein two rollers in each row are arranged between the outer ring and the inner ring; and a groove is arranged on the surface of the inner ring between the two rollers, and is internally provided with the retaining ring. The axial positioning roller bearing has the advantages that the production and the processing are convenient, and the production cost is reduced.
Description
Technical field
The present invention relates to a kind of roller bearing, relate in particular to a kind of axially locating roller bearing.
Background technique
Present roller bearing comprises outer ring, inner ring, seal ring, fastening flange and roller; Wherein inner ring is installed in the outer ring; Every row installs a roller between outer ring and inner ring; On the inner ring of roller one side, be provided with a shaft shoulder; On the inner ring of roller opposite side, be provided with a groove, a fastening flange is installed in groove, between outer ring outside the fastening flange and the shaft shoulder and inner ring, installing respectively has a seal ring; This roller bearing is positioned between outer ring and the inner ring roller with crossing the shaft shoulder and fastening flange, and it is relatively wasted time and energy and will on inner ring, process a shaft shoulder, also compares waste material simultaneously, and the inner ring processing cost is also taught height.
Summary of the invention
To above-mentioned shortcoming, the object of the present invention is to provide the axially locating roller bearing that a kind of production and processing is convenient, cost of production reduces.
Technology contents of the present invention is: a kind of axially locating roller bearing, comprise outer ring, inner ring, seal ring and roller, and wherein inner ring is installed in the outer ring, and roller is installed between outer ring and the inner ring; Between outer ring outside roller and the inner ring seal ring is installed; It is characterized in that it also comprises a back-up ring, every row roller is installed two between outer ring and inner ring, on the inner peripheral surface between two rollers, is provided with a groove, and a back-up ring is installed in the groove.
The advantage that the present invention is compared with prior art had is: through on the inner peripheral surface between two rollers, being provided with a groove; One back-up ring is installed in the groove; Can cancel shaft shoulder processing on the inner ring thus, and deduct fastening flange, convenient, the cost of production reduction of production and processing thus; Every row's roller has one to change two into, has improved the working life and the reliability of bearing thus.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Embodiment
Further narrate the present invention below in conjunction with embodiment and accompanying drawing thereof.
As shown in Figure 1, a kind of axially locating roller bearing comprises outer ring 1, inner ring 2, seal ring 3 and roller 4; Wherein inner ring 2 is installed in the outer ring 1, and roller 4 is installed between outer ring 1 and the inner ring 2; Between the outer ring 1 in roller 4 outsides and inner ring 2, a seal ring 3 is installed; It is characterized in that it also comprises a back-up ring 5, every row roller 4 is installed two between outer ring 1 and inner ring 2, on inner ring 1 surface between two rollers 4, is provided with a groove 4.1, and a back-up ring 5 is installed in the groove 4.1.
