Abstract
The utility model relates to a step shaft bearing installing tool, strikeing sleeve, guide sleeve, compression spring and the spacing post that leads including main, mainly strikeing the microscler guiding hole that sleeve bilateral symmetry position was equipped with the break -over, guide sleeve locates main strikeing inside the sleeve to corresponding two microscler guiding hole position departments and being equipped with the screw thread through -hole, compression spring locates main strikeing between sleeve and the guide sleeve, the spacing post that leads passes the owner and strikes telescopic microscler guiding hole screw in on guide sleeve's screw thread through -hole, treat the bearing of installation and place on the step shaft, but guide sleeve places between the minor diameter axle of step shaft and the bearing inner race that treats the installation just free rotation. The utility model provides a reliably install the bearing in the too big epaxial problem of ladder of diameter ratio, the operation and take care of be convenient for has in addition remedied the not enough of prior art.
Description
Technical field
The utility model relates to a kind of multidiameter bearing installing tool.
Background technology
The pressure roll of chemical fibre industry up-coiler is a kind of not only thin but also long axle; draw ratio is more than 16; generally all make two sections, centre connects with shaft coupling, and the diameter of dress bearing place axle is than large more than 2 times of the diameter filling shaft coupling place axle; when outer power press-in bearing; because the concentricity of bearing and axle can not be ensured, so bearing often can block, if continue firmly press-in can damage axle; if go out bearing with La Mala can damage bearing, maintenance cost is very high.
As shown in Figure 1, it is the bearings mounted schematic diagram of erecting tools of prior art, first bearing 2 is enclosed within multidiameter 1 during installation, roughly ensure the concentricity of bearing 2 and multidiameter 1 by rule of thumb, then the erecting tools 8 of prior art is adjacent to bearing 2, the erecting tools 8 of prior art is knocked with iron hammer, bearing 2 is installed on multidiameter 1, because bearing 2 and multidiameter 1 are interference fit, so the concentricity of bearing 2 and multidiameter 1 absolutely can not be guaranteed when putting bearing 2, just there will be bearing 2 when knocking and be stuck in situation on multidiameter 1, bearing 2 or multidiameter 1 is caused to damage, maintenance penalty is very large.
Summary of the invention
The purpose of this utility model is to provide a kind of multidiameter bearing installing tool, and solve and bearing is reliably arranged on diameter than the problem on excessive multidiameter, also convenient operation and keeping, compensate for the deficiencies in the prior art.
For achieving the above object, the utility model is solved by the following technical programs:
A kind of multidiameter bearing installing tool, comprise master and knock sleeve, pilot sleeve, Compress Spring and guide and limit post, described master knocks the microscler pilot hole that sleeve bilateral symmetry position is provided with break-through, described pilot sleeve is located at described master and is knocked sleeve inner, and corresponding described two microscler pilot hole positions are provided with tapped through hole, described Compress Spring is located at master and is knocked between sleeve and pilot sleeve; Described guide and limit post screws on the tapped through hole of pilot sleeve through the main microscler pilot hole knocking sleeve; Described bearing to be installed is placed on described multidiameter, and described pilot sleeve to be placed between the small diameter shaft of described multidiameter and described bearing inner race to be installed and free to rotate.
As preferred technical scheme:
A kind of multidiameter bearing installing tool described in the utility model, described master knocks at the bottom of the cylinder of sleeve and is provided with blind hole, and described spring one end is placed in blind hole, and the other end is placed in the projection at the bottom of described pilot sleeve urceolus.
A kind of multidiameter bearing installing tool described in the utility model, described bearing to be installed and described multidiameter are arranged with one heart.
A kind of multidiameter bearing installing tool described in the utility model, described guide and limit post, microscler pilot hole, tapped through hole correspondence are provided with two.
The beneficial effects of the utility model are:
A kind of multidiameter bearing installing tool of the present utility model, has fully used the function of spring, guarantees reliable compressing guide sleeve cylinder in bearing installation process, ensures the concentricity of bearing and multidiameter, ensures installation quality; Multiple parts are assembled into an entirety by a kind of multidiameter bearing installing tool of the present utility model dexterously, high in technological content, and are convenient to certainly deposit.

Detailed description of the invention
Below in conjunction with detailed description of the invention, set forth the utility model further.
As shown in Fig. 2-6, a kind of multidiameter bearing installing tool of the present utility model, erecting tools assembly 3 knocks sleeve 4, pilot sleeve 5, Compress Spring 6 and guide and limit post 7 by master and forms.First Compress Spring 6 being put into master during assembling knocks in the blind hole of sleeve 4, then pilot sleeve 5 is put into master and knock sleeve 4, downward pressing also rotates pilot sleeve 5, until see the screwed hole on pilot sleeve 5 by the main elongated hole knocked on sleeve 4 cylinder, then also being screwed in through the main elongated hole knocking sleeve 4 by guide and limit post 7 is arranged on the screwed hole of pilot sleeve 5, define an indivisible entirety, be convenient to keeping and deposit.
As shown in Figures 3 and 4, the cross-sectional schematic that the utility model prepares bearings mounted cross-sectional schematic and installed by bearing respectively, comprise multidiameter 1, bearing 2 and erecting tools assembly 3, when bearing 2 will be installed, first bearing 2 is set on multidiameter 1, again erecting tools assembly 3 is placed on bearing 2, ensure that pilot sleeve 5 to be inserted on the inner ring of bearing 2 and multidiameter 1 between small diameter shaft, and pilot sleeve 5 can freely rotate, then main top of knocking sleeve 4 is knocked with the instrument of knocking, because Compress Spring 6 is downward compressing guide sleeve cylinder 5 always, so pilot sleeve 5 can reliably lead, ensure the concentricity of bearing 2 and multidiameter 1, guarantee that bearing 2 is reliably contained on multidiameter 1.
Prove through test, a kind of multidiameter bearing installing tool of the present utility model really solves and bearing is reliably arranged on diameter than the problem on excessive multidiameter, and also convenient operation and keeping, compensate for the deficiencies in the prior art.
