Abstract
The utility model relates to a tool for installing a bearing. A bearing installing tool is characterized by comprising a tool main body, wherein a shaft hole is arranged in the tool main body, the lower end of the shaft hole is an opening end, the upper end of the shaft hole is closed, the internal diameter of the shaft hole is larger than that of a bearing inner race by 1-10mm; and an inner annular body and an outer annular body are arranged at the lower part of the tool main body, the outer annular body is positioned outside the inner annular body, the outer and the inner annular bodies are arranged into an integral structure, an annular groove is formed between the outer and the inner annular bodies, the external diameter of the inner annular body is smaller than that of the bearing inner race by 0-5mm, and the internal diameter of the outer annular body is larger than that of an bearing outer race by 0-5mm. After the tool is used, the bearing is stressed uniformly, and the bearing is convenient to install.
Description
Technical field
The utility model relates to a kind of bearings mounted instrument that is used for.
Background technology
At present, when bearing is installed, generally adopt hammer directly to beat bearing, the shaft strength inequality, bearing is fragile, the impaired back of bearing fluctuation of service.
Summary of the invention
The purpose of this utility model is to provide a kind of bearing installing tool, and this instrument makes shaft strength even.
To achieve these goals, technical scheme that the utility model adopts is: bearing installing tool is characterized in that: it comprises tool body, be provided with axis hole in the tool body, the lower end of axis hole is an openend, the upper end closed of axis hole, and the internal diameter of axis hole is greater than the internal diameter 1～10mm of bearing inner race; The bottom of tool body is interior annular solid and outer shroud body, the outer ring body is positioned at outside the annular solid, outer shroud body and interior annular solid are structure as a whole, form annular groove between outer shroud body and the interior annular solid, the external diameter of interior annular solid is less than the external diameter 0～5mm of bearing inner race, and the internal diameter of outer shroud body is greater than the internal diameter 0～5mm of bearing outer ring.
The beneficial effects of the utility model are: interior annular solid contacts with bearing inner race, outer shroud body and bearing outer ring contact (the corresponding rolling element of annular groove), and with the upper end of hammer beating tool body, power evenly conduction is given bearing, and shaft strength is even.It is convenient that this instrument is installed bearing.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1-tool body, annular solid in the 2-axis hole, 3-, 4-outer shroud body, 5-annular groove, 6-bearing, 7-axle, 8-bearing inner race, 9-rolling element (as ball), 10-bearing outer ring.Arrow represents to beat direction among the figure.
The specific embodiment
As shown in Figure 1, bearing installing tool, it comprises tool body (body) 1, be provided with axis hole 2 in the tool body 1, the lower end of axis hole 2 is an openend, the upper end closed of axis hole 2, the internal diameter of axis hole 2 is greater than the internal diameter 1～10mm (during use, axle 7 can move in axis hole 2) of bearing inner race; The bottom of tool body 1 is interior annular solid 3 and outer shroud body 4, outer shroud body 4 is positioned at outside the annular solid 3, outer shroud body 4 and interior annular solid 3 are structure as a whole, form annular groove 5 between outer shroud body 4 and the interior annular solid 3, the external diameter of interior annular solid 3 is less than the external diameter 0～5mm of bearing inner race 8, and the internal diameter of outer shroud body 4 is greater than the internal diameter 0～5mm of bearing outer ring.The external diameter of outer shroud body 4 is identical with the external diameter of bearing outer ring 10.Bearing can be rolling bearing.
