Abstract
The utility model relates to a bearing taking-out tool, which is composed of an upper sleeve, a lower sleeve, a nut and a screw stem, wherein the front end of the inner hole the upper sleeve and the lower sleeve is provided with a 45-degree angle; the angle and the chamfer of the outer ring of the bearing are connected together; the inner holes of the upper sleeve and the lower sleeve are larger and the outer diameter of the bearing; the length of the inner hole is larger than the thickness of the bearing; the rear parts of the inner hole of the upper sleeve and the lower sleeve are provided with a screw thread hole; the outside parts of the upper sleeve and the lower sleeve are screw threads; the nut matches with the external screw threads of the upper sleeve and the lower sleeve; and the upper sleeve and the lower sleeve compose an entirety; the screw stem is composed of screw threads and a hexagonal head; and the screw stem matches with the screw thread hole of an entirety formed by the upper sleeve and the lower sleeve. The screw stem contacts the end of an axle body in the bearing through the inner screw threads of the upper sleeve and the lower sleeve. By then the screw stem is rotated to make the 45-degree angle at the front ends of the upper sleeve and the lower sleeve to contact the chamfer of the outer ring of the bearing and drive the bearing to separate from the axle body.
Description
Technical field
The utility model relates to a kind of, the instrument that bearing takes out.This instrument is applicable to the taking-up of all size bearing, and this instrument is not subjected to the restriction of space structure simultaneously.
Technical background
On the market many kinds of fetching tool of bearing are arranged now.They are normally by a big nut, and the nut outside is installed several dog clutch and lived the outer ring of bearing.A screw rod withstands the termination of the axis body in the bearing by big nut, and rotary screw makes shaft strength, causes bearing to withdraw from from axis body.It is bigger that these instruments can only be used for bearing specification, the position that the space is rather spacious, but for the bearing of some small dimensions and the position of limited space, the taking-up of bearing just can not have been used the taking-up instrument of said structure.Some factories are when the bearing of dismounting small dimension, and the workman who has only dismantles with several simple tools, as punching pin, is with the pin of tapering etc., through regular meeting with product and damage of bearings.
Summary of the invention
The purpose of this utility model is that a kind of a kind of instrument that can take out from axis body the bearing of all size is provided.Simultaneously not limited by structure space.。
The purpose of this utility model is to realize like this.
It comprises upper sleeve body, following body, nut, screw rod a kind of fetching tool of bearing, and upper sleeve body, following body are fixed as one by nut, and the endoporus front end of upper sleeve body, following body has miter angle; Screw rod is threaded with upper sleeve body and following body.The utility model has the advantages that, in the employing, the angle of following body internal thread front end contacts with the outer ring chamfering of bearing, on, the endoporus of following body is greater than the external diameter of bearing, the thickness that the length of endoporus is greater than bearing adds that axis body stretches the length of bearing face, on, the endoporus rear portion of following body is a screwed hole, on, the outside of following body is the structure of screw thread, make the screw thread of nut and last, the external screw thread of following body matches, thereby make, following body forms a whole, screw flight and last, screwed hole after following body forms a whole matches, it is last that screw rod is passed through, axis body termination in the internal thread of following body and the bearing contacts, at this moment rotary screw makes, front end 45 degree of following body contact and drive bearing with the bearing outer ring chamfering and spin off from axis body.The utility model volume is little, and is in light weight, easy and simple to handle, not limited by structure space, particularly when the bearing that is used for small dimension takes out, can not damage bearing.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of upper sleeve body, following body;
Fig. 3 is that the A of Fig. 2 is to structural representation.
The specific embodiment
Concrete structure of the present utility model is provided by the following drawings explanation and enforcement.
Fetching tool of bearing is made up of nut 1, upper sleeve body 2, screw rod 3, following body 4.Upper sleeve body 1 is two identical parts with following body 4, and they are made up of 45 degree wedge angles 5, endoporus 6, internal thread 8 and external screw thread 7.Its main function is, upper and lower body fastens bearing, and the diameter of the degree of 45 on upper and lower body wedge angle 5 must be less than bearing outer ring 3～4MM, and contacts with the outer ring chamfering of bearing.Upper and lower body diameter of bore is greater than bearing outside diameter 3～4MM, and the length of endoporus 6 is greater than the width of bearing, adds that axis body stretches out the length of bearing face.The length of internal thread 8 can not be less than 20MM.When upper and lower body 2,4 fastened bearing, nut 1 matched with the external screw thread 7 of upper and lower body 2,4, makes, and following body 2,4 is fixed together, and the effective length of nut 1 can not be less than 20MM.Screw rod 3 divides 9 to form by threaded portion and six quadrate parts.Screw rod 3 matches with the internal thread of upper and lower body 2,4 (being fixed together with nut 1), rotary screw 3, and the termination that makes screw rod contact the continuation rotary screw with axis body termination in the bearing
Make, 45 degree wedge angles 5 of following body contact with the bearing outer ring chamfering, and the drive bearing spins off from axis body.Realize the taking-up of bearing.
