Description
Technical field
The present invention relates to urban rail car axle box bearing technology of pressure mounting field, and in particular to a kind of axle box bearing built-in wheel pair
Bearing press mounting frock and pressing method.
Background technology
The urban rail car wheel of conventional structure is to being all assembly of axle box bearings in the outside of wheel relative position, axle box bearing pressure
Two wheel supporting axletree keep levels are utilized during dress, bearing press mounting frock is assembled on axle shaft end screw hole, using can
Portable or fixed bearing press, produce reaction force using axle shaft end screw hole and bearing is pressed on axletree.
A small number of urban rail cars use axle box bearing built-in wheel pair, and its axle box bearing is in the inner side of wheel relative position, pressure
Wheel is not pressed when filling bearing, can not be supported using wheel, and axle box bearing built-in wheel does not have to axle shaft end
Available head screwed hole.Therefore, the bearing press mounting frock of conventional structure can not complete the axle of axle box bearing built-in wheel pair
Pressure-bearing fills work.
The content of the invention
In order to solve the skill that existing bearing press mounting frock can not complete the bearing press mounting work of axle box bearing built-in wheel pair
Art problem, the present invention provide a kind of the bearing press mounting frock and pressing method of axle box bearing built-in wheel pair.
The technical solution adopted for solving the technical problem of the present invention is as follows：
The bearing press mounting frock of axle box bearing built-in wheel pair, it, which includes chassis, baffle plate and two V-type seats, chassis, includes
Front vertical plate and bottom plate, front vertical plate are fixed on the front end of bottom plate, and front vertical plate is provided with a central through hole and four connecting holes；Baffle plate
The rear end of bottom plate is bolted on, two V-type seats are placed on, and between front vertical plate and baffle plate.
The pressing method of bearing press mounting frock based on above-mentioned axle box bearing built-in wheel pair, it comprises the following steps：
The first step, bearing to be pressed is put into axle box, will be relatively fixed using jump ring between bearing and axle box；
Second step, axletree is sling with lifting machine be put on two V-type seats, axletree keep level, one end of axletree leans
Onto baffle plate, the other end prepares pressing bearing；By the axle box described in the first step and bearing holder (housing, cover) on axletree wheel seat；
3rd step, before shifting packaged type bearing press the front vertical plate of chassis onto, stood by four bolt and nuts with preceding
Four screws of plate coordinate, and bearing press and front vertical plate are connected, adjust the height of bearing press, by bearing head
With bearing inner race position correspondence；
4th step, start bearing press, by bearing head by the correct position on bearing press mounting to axletree, and pass through
The observation bearing press pressure assembling force that shows determines whether bearing press mounting is qualified.
The beneficial effects of the invention are as follows：The bearing press mounting frock uses two V-type seat supports axletree keep levels, using gear
The cooperation of screw on plate and front vertical plate, provide reaction force for press fitting and realize bearing press mounting, and can be realized during press fitting
Monitor bearing press mounting power and adhesive force.The frock is simple to operate, simple in construction, low manufacture cost, and is easy to safeguard.
Brief description of the drawings
Fig. 1 is the structural representation of the bearing press mounting frock of axle box bearing built-in wheel pair of the present invention.
Fig. 2 is the application structure schematic diagram of the bearing press mounting frock of axle box bearing built-in wheel pair of the present invention.
Embodiment
The present invention is described in further details with reference to the accompanying drawings and examples.
As depicted in figs. 1 and 2, the bearing press mounting frock of axle box bearing built-in wheel pair of the present invention includes chassis 1, baffle plate 2
With two V-type seats 3, chassis 1 includes front vertical plate 1-1 and bottom plate 1-2, and front vertical plate 1-1 is fixed on bottom plate 1-2 front end, front vertical plate
1-1 is provided with a central through hole and four screws.According to axletree entire length, relative position of the baffle plate 2 on chassis 1 is confirmed
Put, using the screw of six M20 × 50 by the fixation on bottom plate 1-2 of baffle plate 2.According to the structure and size of wheel pair, two are determined
The particular location of individual V-type seat 3, two V-type seats 3 are placed on bottom plate 1-2, and between front vertical plate 1-1 and baffle plate 2.
The process being pressed using the bearing press mounting frock of axle box bearing built-in wheel pair of the present invention to bearing is：By axle
Hold and be put into axle box, will be relatively fixed using jump ring between bearing and axle box；Axletree 6 is hung onto into two V-types with lifting machine
On seat 3, the keep level of axletree 6, one end of axletree 6 is leaned on baffle plate 2, and the other end prepares pressing bearing；By axle box and bearing
Component 5 is temporarily nested on axletree wheel seat, and the outer end of axletree 6 is wheel seat, and wheel seat external diameter is smaller than bearing block external diameter；By packaged type
Bearing press, before shifting the front vertical plate 1-1 of chassis 1 onto, four screw rods are through four connecting holes on front vertical plate 1-1 and using big
Nut is fixed；The height of packaged type bearing press is adjusted, by bearing head 4 and bearing inner race position correspondence；Start bearing
Pressing machine, by bearing head 4 by the correct position on bearing press mounting to axletree 6, the pressure shown by observing bearing press
Power is filled, determines whether bearing press mounting is qualified.
