Abstract
Formal dress formula angular contact ball bearing pretightning force testing arrangement, including strutting arrangement, bearing installation fixing device and loading device, strutting arrangement comprises meet an emergency foot and work platform, bearing installation fixing device is including test axle, first screw, locating pin, first gland, left angular contact ball bearing, right angular contact ball bearing, bearing frame, second gland and second screw, loading device includes steel ball, sensor, spacer and lock nut. The utility model discloses structural design is simple reasonable, easy operation, and it is convenient and reliable to adjust the pretightning force, size that can the accurate determination of pretightning force.
Description
Technical field
The utility model relates to a kind of bearing device for measuring force, is specifically related to a kind of positive-installed angular contact ball bearing pretightning force proving installation.
Background technology
At present, in engineering except the occasion not high for ask for something has some simple pretightning force evaluation methods, determine that the method for bearing pre-fastening mainly adopts two kinds: one to be empirical method, namely feeless method; Two is according to axle=to LOAD FOR pretightning force or axial deflection.These two kinds of methods all need the related components such as repeated disassembled and assembled bearing or cushion cover to carry out gap adjustment in the process of test pretightning force, and the two all has inefficiency, labour intensity is large, and operation link complexity waits common ground, and all has certain limitation.For special occasions and some high-precision bearings systems, the pretension force value accuracy requirement of bearing bearing reality is high, the repeated disassembled and assembled even do not allowed repeatedly had.
Utility model content
In order to solve the technical matters of above-mentioned existence, the utility model adopts following technical proposals: positive-installed angular contact ball bearing pretightning force proving installation, comprise bracing or strutting arrangement, bearing fixing device for installing and charger, described bracing or strutting arrangement is by straining pin and workbench is formed, described bearing fixing device for installing comprises test axle, the first screw, register pin, the first gland, left comer contact ball bearing, right corner contact ball bearing, bearing seat, the second gland and the second screw, and described charger comprises steel ball, sensor, spacer and set nut.
Described bearing seat is fixed on workbench upper surface by screw and register pin.
The left cover face of described first gland contacts with the outer ring of right corner contact ball bearing and coordinates.
The outer ring of described left comer contact ball bearing contacts with the right cover face of the second gland and coordinates.
Described charger and the first gland closely cooperate.
The beneficial effects of the utility model are: structural design advantages of simple, simple to operate, regulate pretightning force convenient and reliable, can the size of Accurate Determining pretightning force.
Accompanying drawing explanation
Fig. 1 is cross-sectional view of the present utility model;
Fig. 2 is the cross-sectional view of the utility model charger.
Embodiment
As shown in Figure 1-2, positive-installed angular contact ball bearing pretightning force proving installation, comprise bracing or strutting arrangement, bearing fixing device for installing and charger 6, described bracing or strutting arrangement is by straining pin 1 and workbench 2 is formed, described bearing fixing device for installing comprises test axle 3, first screw 4, register pin 5, first gland 7, left comer contact ball bearing 81, right corner contact ball bearing 82, bearing seat 9, second gland 10 and the second screw 11, described test axle 3 is through bearing seat 9, described bearing seat 9 is fixed on workbench 2 upper surface by screw 4 and register pin 5, bearing seat 9 adopts stiffness better, and the bearing seat of sternly joining with corresponding bearing size, positive-installed angular contact ball bearing is a kind of formula angular contact ball bearing face-to-face, the left cover face of described first gland 7 contacts with the outer ring of right corner contact ball bearing 82 and coordinates, the outer ring of described left comer contact ball bearing 81 contacts with the right cover face of the second gland 10 and coordinates, when part external force is pressed in the outer ring of right corner contact ball bearing 82 by the first gland 7, due to the effect of bearing contact angle, be delivered to the inner ring of left comer contact ball bearing 81 through test axle 3 by right corner contact ball bearing 82 inner ring by ball, equally due to the effect of bearing contact angle, the outer ring of left comer contact ball bearing 81 is delivered to by ball, by the second screw 11, power is delivered on bearing seat 9 by the second gland 10 again, complete the pretension of bearing, described charger 6 left end and the first gland 7 closely cooperate, charger 6 comprises steel ball 61, sensor 62, spacer 63 and set nut 64, for the applying of pretightning force and the collection of force signal, realize mainly through charger 6, process is that external force is applied on sensor 62 through set nut 4, and be delivered on the first gland of left end by steel ball 1, simultaneously due to the retroaction of power, force signal exports computer acquisition and disposal system to by sensor 62.
