Abstract
The utility model relates to a bearing spacer sleeve, the spacer sleeve be installing in rotatory epaxial cylinder shaped casing shape structure, the thickness at middle part is big than both ends, the external diameter of the position that thickness is big on be provided with rectangular thread. The utility model discloses improve the lubricated condition of bearing, increase the life cycle of bearing, guarantee whole mechanical system's operational reliability, have the characteristics that rigidity is big, operational reliability is high.
Description
Technical field
This utility model relates to a kind of bearing spacer sleeve in mechanical component.
Background technology
Bearing is widely used revolving member in machine driving, and the supporting being generally used on axle point-to-point transmission, in two bearings, interannular carries out axial limiting by bearing spacer sleeve.Common bearing spacer sleeve is cylindrical sleeves structure, as it is shown in figure 1, by bearing guard shoulder limitation in height, spacer sleeve thinner thickness, rigidity is poor.Meanwhile, during bearing lubrication, good lubricating condition can be obtained when directly being lubricated by nozzle, but when general splash lubrication, lubricating condition is poor, and lubricating condition tends to severe when lubricants capacity reduces, break down so that whole mechanical system is run.
Summary of the invention
The purpose of this utility model is in that to provide a kind of bearing spacer sleeve improving bearing lubrication condition, has that rigidity is big, operational reliability high simultaneously.
Concrete technical scheme of the present utility model is, described bearing spacer sleeve is installation cylindrical sleeve structure on the rotary shaft, the two ends of spacer sleeve withstand on the internal ring of two block bearings, the thickness at the middle part of described spacer sleeve is big compared with two ends, and the external diameter of the position that described thickness is big is provided with rectangular thread.
Bearing spacer sleeve interior thickness of the present utility model strengthens, and increases the rigidity that bearing spacer sleeve is overall；Simultaneously, it is provided with screw thread, part lubricating oil can be stored, when splash lubrication or lubricants capacity reduce suddenly, it is stored in the lubricating oil in thread pitch and the lubricating oil of a bearing part can be provided, thus improving the lubricating condition of bearing, increase the life cycle of bearing, it is ensured that the operational reliability of whole mechanical system.This utility model has improved on original structure basis, has the advantages that rigidity is big, operational reliability is high.
Accompanying drawing explanation
Fig. 1 is the structural representation of former bearing spacer sleeve；
Fig. 2 is structural representation of the present utility model.
Detailed description of the invention
As shown in the figure, bearing spacer sleeve is installation cylindrical sleeve structure on the rotary shaft, the two ends of spacer sleeve withstand on the internal ring of two block bearings, and the thickness at the middle part of described spacer sleeve is big compared with two ends, and the external diameter of the position that described thickness is big is provided with rectangular thread 1.
Claims (1)
1. a bearing spacer sleeve, it is characterized in that, described bearing spacer sleeve is installation cylindrical sleeve structure on the rotary shaft, the two ends of spacer sleeve withstand on the internal ring of two block bearings, the thickness at the middle part of described spacer sleeve is big compared with two ends, and the external diameter of the position that described thickness is big is provided with rectangular thread (1).
