Abstract
The invention discloses an installation tool special for fixing a bearing by means of a roller-type ring-shaped rolling bearing seat. The installation tool comprises a mandrel, a cylindrical roller, a holding rack, a locating sleeve, a locating pin and a jackscrew. The locating sleeve and the holding rack are installed together in series by means of the locating pin through a center hole formed in the locating sleeve and a center hole formed in the holding rack; the cylindrical face opening face A of the holding rack faces outwards, the spherical surface of the roller points to a center hole of the holding rack to be pushed into the cylindrical surface of the holding rack, the locating pin is inserted into a center hole of the mandrel, all the parts are tightly attached with one another, and the locating pin is fixed on the mandrel by means of the jackscrew through a cylindrical side face threaded hole of the mandrel. The installation tool is advanced in design principle, relatively simple in structure, low in making cost, reliable, firm, durable in use and convenient to operate. A spinning part can be precisely controlled, the radial force applied to a bearing outer ring is small, it is proved through multi-batch production that all relevant requirements can be met through one-time rolling, and the purpose of fixing the bearing through closing of the ring-shaped rolling bearing seat can be completely achieved.
Description
Technical field
The invention belongs to Machining Technology field, be specifically related to a kind of roller ring-type rolling shaft bearing and fix
The special installation tool of bearing.
Background technology
It it is the key that effectively plays a role of bearing in qualified bearing is fixed on qualified bearing saddle bore on request
Link.It is most common method that ring-type rolling shaft bearing fixes bearing.Ring-type rolling shaft bearing fixes bearing
Method mainly has the methods such as steel ball rolling, roller rolling.During steel ball rolling, due to rolling and the operation of steel ball
Track can not effectively control, and often occurs that steel ball slides, and irregular or ring-type impression, scratch occurs in flange,
Surface roughness is undesirable.Owing to being limited by steel ball cross sectional shape, flange and bearing chamfer break joint
Gap is excessive.Roller rolling device structure is complicated, and between two rollers, spacing is difficult to accurately control, roller installing hole and
Installing axle need to mutually rotate, by radial force and the comprehensive function of axial force, there is beat in roller, and roller is pacified
Dress hole seamed edge constantly gnaws installation axle in both direction and cross section, installs and occurs that groove, roller are difficult on axle
Flexible rotating on the mounting shaft, roller slides on bearing block, and roller beat is serious, causes rolling position difficult
Accurately to control.Two kinds of rolling depression methods can cause extruding axial force and not reach required value, outside excessive compression bearing
Circle, affects Bearing inner gap, roll bearing swing and rotation dumb；Rolling is repeated several times the most undesirable,
Can only worn bearing seat.
Summary of the invention
It is an object of the invention to: manufacture and design a kind of roller ring-type rolling shaft bearing and fix the special peace of bearing
Holding tool, solves steel ball rolling, the deficiency of roller rolling depression method and defect, meets ring-type rolling shaft bearing and receives
The demand of the fixing bearing of mouth.
Technical scheme: a kind of roller ring-type rolling shaft bearing fixes the special installation tool of bearing,
It is characterized in that: comprise mandrel 1, cylindrical roller 2, retainer 3, positioning sleeve 4, alignment pin 5, jackscrew 6；
With alignment pin 5, positioning sleeve 4, retainer 3 is in tandem together by its centre bore, retainer 3 cylinder opening
Face A is outside, opening surface has three axis uniform centered by retainer 3 centre bore axis meet at one
The cylinder inclined hole of point, pushes in retainer 3 cylinder inclined hole by cylindrical roller 2 sphere sensing retainer 3 center,
Each part is mutually adjacent to, and with jackscrew 6, by mandrel 1 cylindrical side screwed hole, alignment pin 5 is fixed on mandrel 1
On.
Mandrel 1 end face has a V-type annular groove, and V-type angle is 90 °, and V-groove inclination angle is α, cylindrical roller
2 spheres are fallen in V-type annular groove by retainer 3 center cylinder inclined hole.
Beneficial effects of the present invention: it is former that roller ring-type rolling shaft bearing fixes the design of bearing special installation tool
Reason advanced person, structure is relatively easy, and cost of manufacture is low, reliable, solid, durable, easy to operate.Roller exists
Mandrel goes in ring and runs on track is RADIAL location, axial point location, registration, stable, it is possible to precisely
Controlling spinning position, roller is substantially reduced with mandrel frictional force, it is ensured that roller rolls flexibly；Roller length model
Enclose the contact of interior all fronts, stop unbalance stress and eccentric wear occurs, extend tool life.According to plastic deformation body
Long-pending principle of invariance design roller bus orientational cone-shaped surface angle [alpha], the radial force applied to bearing outer ring is little, passes through
Multiple batches of production is verified, once rolls, can meet all related requests, is fully able to reach ring-type rolling
Bearing block closes up and fixes the purpose of bearing.

Detailed description of the invention
In conjunction with accompanying drawing, invention is described in further detail:
As shown in Figures 1 to 4, a kind of roller ring-type rolling shaft bearing fixes the special installation tool of bearing,
Comprise mandrel 1, cylindrical roller 2, retainer 3, positioning sleeve 4, alignment pin 5, jackscrew 6；With alignment pin 5
Positioning sleeve 4, retainer 3 is in tandem together by its centre bore, and retainer 3 cylinder opening A is outside,
Three axis uniform centered by retainer 3 centre bore axis are had to meet at any cylinder on opening surface oblique
Hole, pushes in retainer 3 cylinder inclined hole by cylindrical roller 2 sphere sensing retainer 3 center, each part phase
It is adjacent to mutually, with jackscrew 6, alignment pin 5 is fixed on mandrel 1 by mandrel 1 cylindrical side screwed hole, core
Axle 1 end face has a V-type annular groove, and V-type angle is 90 °, and V-groove inclination angle is α, cylindrical roller 2 sphere
Fallen in V-type annular groove by retainer 3 center cylinder inclined hole.
During as it is shown in figure 5, use specific purpose tool rolling shaft bearing, base 10 is placed on Drilling machines bench,
The bearing block 9 pushing bearing 7,8 is put on base 10 with end face and bearing inner race 7 Internal hole positioning, uses
Drill chuck on drill press spindle clamps specific purpose tool top installing handle, depresses drilling machine rocking arm, moves base 10 simultaneously,
Make positioning sleeve 4 on specific purpose tool can pass in and out bearing inner race 7 endoporus flexibly, with pressing plate, base 10 is fixed on
On Drilling machines bench, so far, mounting and adjusting is complete.The bearing block 9 pushing bearing 7,8 is put into base 10
On, start drilling machine, the most afterburning by drilling machine rocking arm, rolling shaft bearing 9, measure pressure by force cell
Power, when pressure arrives setting, completes the rolling of this face.The like, complete another side or other bearing block
Rolling.
