Abstract
The invention discloses an assembly tool for a compact type bearing assembly and belongs to the field of bearing machining. The assembly tool is characterized by comprising a pressing sleeve (1), a guide sleeve (2), a locating bolt (3) and a shaft (5). The locating bolt (3) is designed according to a bolt hole in the end of the shaft (5). The diameter of the guide sleeve (2) is 0.4-0.5 mm smaller than that of the shaft (5). A bearing (4) is mounted on the guide sleeve (2) and is in small clearance fit with the guide sleeve (2). The clearance between the pressing sleeve (1) and the guide sleeve (2) ranges from 0.7 mm to 0.8 mm. The outer diameter of the pressing sleeve (1) is designed according to the outer diameter of a part needing press fitting and just needs to be slightly smaller than the outer diameter of the press fitting part. The length of the pressing sleeve (1) and the length of the guide sleeve (2) are designed according to the width of the bearing (4) so as to ensure the travel distance. Two 180-degree long grooves are formed in the pressing sleeve (1) and the guide sleeve (2). The assembly tool for the compact type bearing assembly solves the problem that when the compact type bearing assembly is installed in the press fitting mode, a tool is needed due to large interference and a long press fitting travel distance of the bearing.
Description
Technical field
The invention belongs to bearing machining field, relate in particular to a kind of compact bearings component assembling frock.
Background technology
In compact bearings assembly, be pre-charged with lubricating grease and be with sealing ring, during because of buying, bearing is an assembly, can not adopt hot charge practice that bearing is installed, and can only install with press-fiting method; This bearing interference is larger, and press-mounting stroke is longer, therefore need to use frock.
Summary of the invention
The object of this invention is to provide a kind of compact bearings component assembling frock, solved compact bearings assembly adopt when press-fiting method and installing because of bearing interference is large and press-mounting stroke length need to use the problem of frock.
In order to achieve the above object, the present invention by the following technical solutions: a kind of compact bearings component assembling frock, comprises gland, fairlead, bolt and axle; Wherein utilize bolts at axle end hole Design Orientation bolt, fairlead is than the little 0.4 ~ 0.5mm of the diameter of axle, it is little matched in clearance that bearing is mounted to fairlead position and bearing and fairlead, the gap of gland and fairlead is 0.7 ~ 0.8mm, the external diameter of gland press-fits the external diameter design at position as required, and more smaller than the external diameter that press-fits position, the length of gland and fairlead designs according to the width of bearing, assurance stroke is made two elongated slots of 180 ° on gland and fairlead.
A compact bearings component assembling frock, wherein, also can make fairlead toply, with center hole, adds strong fix.
The invention has the beneficial effects as follows: a kind of compact bearings component assembling frock is provided, improved production efficiency after using this frock, and this frock making has been simple, simple to operate, practical, be convenient to promote.
Accompanying drawing explanation
Fig. 1 is the structural representation of compact bearings component assembling frock.
In figure, 1, gland, 2, fairlead, 3, bolt, 4, bearing, 5, axle.
The specific embodiment
Below in conjunction with accompanying drawing, the present invention will be further described.
A compact bearings component assembling frock, comprises gland 1, fairlead 2, bolt 3 and axle 5; Utilize axle 5 terminal bolt hole Design Orientation bolts 3, a fairlead 2 is installed, fairlead 2 is more smaller than the diameter of axle 5, is convenient to bearing and is mounted to fairlead 2 positions, and fairlead 2 and bearing 4 are little matched in clearance, and fairlead 2 is than the little 0.4 ~ 0.5mm of axle 5 diameter; This gap can not be too large, otherwise fairlead may not have effect, can not guarantee that bearing is vertically pressed into axle journal, and the design of this gap being advisable bearing assemble to fairlead.
Gland 1 can suitably strengthen with the gap of fairlead 2, be 0.7 ~ 0.8mm, the external diameter of gland 1 press-fits the external diameter design at position as required, more smaller than the external diameter that press-fits position, be subject to product to tie enough impacts, some gland wall thickness are thinner, and pressure assembling force is larger, it is modified that now the material of gland 1 can be selected No. 45 steel, and the position contacting with forcing press is designed to sphere, can guarantee that pressure passes through center all the time; The length of gland 1 and fairlead 2 designs according to the width of bearing 4, guarantees stroke; The key of this Fixture Design is the selection of the fit tolerance of fairlead and bearing, in addition, also fairlead 2 can be made toply, with center hole, adds strong fix; Finally on gland 1 and fairlead 2, make two elongated slots of 180 °, during use, with crowbar, pass long slot bore, as lifting device, be convenient to fitting operation.
Compact bearings assembly bearing it should be noted that while press-fiting that rampiston center line and center line of journal should keep coaxial, press-fits and in process, answers swivel bearing outer ring, whole, must keep its rotation flexibly freely in press-fiting process, if stuck, stop press-fiting, and move back and unload inspection.
The present invention does not describe part in detail, is those skilled in the art of the present technique's known technology.
Claims (2)
1. a compact bearings component assembling frock, is characterized in that: comprise gland (1), fairlead (2), bolt (3) and axle (5), wherein utilize axle (5) terminal bolt hole Design Orientation bolt (3), fairlead (2) is than the little 0.4 ~ 0.5mm of diameter of axle (5), bearing (4) is mounted to fairlead (2) position and bearing (4) and fairlead (2) for little matched in clearance, gland (1) is 0.7 ~ 0.8mm with the gap of fairlead (2), the external diameter of gland (1) press-fits the external diameter design at position as required, more smaller than the external diameter that press-fits position, the length of gland (1) and fairlead (2) designs according to the width of bearing (4), assurance stroke, on gland (1) and fairlead (2), make two elongated slots of 180 °.
2. a kind of compact bearings component assembling frock according to claim 1, is characterized in that: wherein, also fairlead (2) can be made toply, with center hole, add strong fix.
