Abstract
The utility model discloses a pull-out tool for a bearing outer ring. The pull-out tool is composed of a bolt, a step shaft and ejector rods, wherein a threaded through hole is formed on the step shaft axially and matched with the bolt, the large end of the step shaft is provided with two to eight radial holes, and the ejector rods are positioned in the radial holes; the front end of the bolt is a cone and the back end of the bolt is a cylinder; the axis of the threaded through hole is perpendicular to the axis of the radial holes; the front end of each ejector rod is a sphere, the tail end of each ejector rod is a cone, and the tail ends of the ejector rods contact with the front end of the bolt when the bolt enters the inside of the threaded through hole. During usage, the large end of the step shaft is firstly placed into a bearing hole, then, the bolt advances towards the step shaft large end direction in a rotating mode until the ejector rods in the radial holes tightly abut against the bearing outer ring, and finally the bearing outer ring is pulled out directly through the tool. The whole operation process is simple and rapid, and time for maintenance is effectively shortened.
Description
Technical field
The utility model relates to the machine upkeep instrument, and particularly a kind of bearing outer ring takes out instrument.
Background technology
At present in the restriction because of working environment of the bearing of wire-drawing machine winding seat, can't charging-up lubricant oil, and the bearing rotating speed is higher, the situation of separating often appears in bearing outer ring and inner ring.Bearing outer ring is with after inner ring separates, and the outer ring is stuck in and is difficult in the hole taking out, and need weld an iron staff during maintenance in the outer ring because dead eye is more not easy to operate, during welding iron staff easily and bearing block weld together, repair very consuming time.
The utility model content
In order to address the above problem, to the utility model proposes a kind of bearing outer ring and take out instrument.
It is as follows that bearing outer ring of the present utility model takes out instrument:
Formed by bolt, Step Shaft and push rod, wherein Step Shaft axially have a tapped through hole, tapped through hole coordinates with bolt, the large end of Step Shaft has 2～8 radial holes, push rod is positioned at radial hole.
The utility model as above illustrates further, and described bolt front end is cone, and tail end is cylinder.
The utility model as above illustrates further, and the axis of described tapped through hole is vertical with the axis of radial hole.
The utility model as above illustrates further, and described push rod front end is sphere, and tail end is cone, when bolt enters tapped through hole inside, and end in contact before push rod tail end and bolt.
The beneficial effects of the utility model are:
At first the utility model puts into the large end of Step Shaft dead eye inside in use, then bolt is advanced to the large extreme direction rotation of Step Shaft, until the push rod in radial hole holds out against bearing outer ring, directly extracts bearing outer ring with instrument at last.Whole operating process simple and fast has effectively shortened and has keeped in repair the required time.
Description of drawings
Fig. 1 is the utility model side sectional view.
Fig. 2 is for using schematic diagram of the present utility model.
The specific embodiment
Below in conjunction with figure and specific embodiment, further illustrate the utility model patented technology.
The utility model is comprised of bolt 1, Step Shaft 2 and push rod 3, wherein Step Shaft 2 axially have a tapped through hole 201, tapped through hole 201 coordinates with bolt 1, the large end of Step Shaft 2 has 2～8 radial holes 202, push rod 3 is positioned at radial hole 202.Described bolt 1 front end is cone, and tail end is cylinder.The axis of described tapped through hole 201 is vertical with the axis of radial hole 202.Described push rod 3 front ends are sphere, and tail end is cone, when bolt 1 enters tapped through hole 201 inside, and push rod 3 tail ends and the front end in contact of bolt 1.At first the utility model puts into the large end of Step Shaft 2 dead eye 4 inside in use, then bolt 1 is rotated to the large extreme direction of Step Shaft 2 and advances, until the push rod 3 in radial hole 202 holds out against bearing outer ring 5, directly extracts bearing outer ring 5 with instrument at last.
The above has carried out exemplary description to the specific embodiment of the present utility model by reference to the accompanying drawings, and obviously the utility model is not limited to this, and the various remodeling that carry out in the utility model scope all do not exceed protection domain of the present utility model.
