Description
Technical field
The present invention relates to Automatic manual transmission instrument, particularly relate to a kind of portable bearing installing tool.
Background technology
In industrial processes, usually can run into the situation of running in bearings on axial workpiece.Such as, in breaker assembly shop, just need a large amount of on the power transmission shaft in Crankarm box, bearing to be installed.
The assembling of bearing is undertaken by the pure craft of manpower at first, what adopt is that workman uses "painted-face" character in opera to knock the mode of bearing along bearing outer ring, adopt in this way running in bearings time, owing to being localized contact between "painted-face" character in opera and bearing, unbalance stress, be easy to the situation that bearing inclination occurs, in addition, owing to being by manually knocking, inclined situation is struck in unavoidable there will be, this kind of situation is once occur, then "painted-face" character in opera just can strike on the inner ring of bearing or strike on axle sleeve, if copper strikes on bearing outer ring, then knock produced power and after the rolling element of bearing, inner ring can be reached again, easily cause the distortion of rolling element, affect the normal use of bearing, if "painted-face" character in opera strikes on axle, then can make the respective end surface irregularity of axle, affect axle surface quality, moreover employing is knocked bearings mounted mode and sometimes also be there will be the situation that workman knocks hand, easily causes accident.
Existence in view of the above problems, has occurred in industrial production with hot charge practice and the bearings mounted technology of cold charge.Cold charge is that axle is put into low temperature environment, such as, axle is put into low temperature liquid nitrogen, and axle is by cold events, then take out running in bearings with instrument, along with the rise of temperature, axle expands, complete and bearing fit, the method is simple, but needs low temperature liquid nitrogen, low temperature liquid nitrogen needs ultralow temperature to preserve, cost is high, and the use of liquid nitrogen, also exists higher safety requirements simultaneously, require strict operational procedure, and be equipped with required protective articles.Hot charge practice is first to bearing heating, and such as, by high temperature spray gun heating bearing, bearing expanded by heating, then on assembly axis, after cooling, bearing shrinks, and complete and the coordinating of axle, the method also needs high temperature heat source, is also uneconomical, not too safe method.
Although above-mentioned two kinds of methods can reduce the damage to bearing and axle, improve the installation accuracy of bearing and axle, but all there is the defect of high cost, be nowadays also only obtain application in the field that some are special, it is not extensively promoted.Particularly in field of circuit breakers, because Crankarm box is welded inconvenient mobile, implement said method particularly difficult.
Summary of the invention
The object of the present invention is to provide a kind of portable bearing installing tool, with solve Crankarm box power transmission shaft install bearing inconvenience, and at power transmission shaft and bearing flimsy problem in installation process.
In order to solve the problem, portable bearing installing tool of the present invention is by the following technical solutions: portable bearing installing tool, comprise support, for push bearing inner race press mold and for ordering about the press mold driving mechanism that press mold moves along a straight line, described support comprises supporting leg, one end of supporting leg be provided with on being welded with Crankarm box, be positioned at the external screw thread that the screwed hole around dead eye coordinates, press mold driving mechanism comprises the screw-nut body be assemblied on support, and press mold rotates one end place being assemblied in the leading screw of screw-nut body.
Described press mold has for leading the endoporus coordinated with the power transmission shaft of Crankarm box.
Described leading screw is coordinated with being felt relieved by fixing structure between press mold.
Thrust bearing is provided with between described leading screw and press mold.
Described thrust bearing is self-aligning thrust roller bearing.
At use portable bearing installing tool of the present invention on the power transmission shaft of Crankarm box during running in bearings, can be first assemblied on corresponding Crankarm box is welded by the external screw thread of supporting leg respective end, then by driving feed screw nut then can realize press-fiting bearing, in the process press-fited, press mold is fitted with the inner ring of bearing all the time, thus bearing inner race each portion uniform force can be ensured, ensure that bearing is not damaged, meanwhile, owing to having abandoned the mode of knocking installation, thus also completely eliminate axle and struck bad possibility.In sum, portable bearing installing tool of the present invention uses together with can being welded with corresponding Crankarm box at any time, convenient, flexible, the mode of pressing bearing then substantially increases the installation effectiveness to bearing, reduce the destructiveness to bearing and axle, the invention solves Crankarm box power transmission shaft install bearing inconvenience, and at power transmission shaft and bearing flimsy problem in installation process.
Further, press mold arranges the endoporus coordinated with the power transmission shaft of Crankarm box and can ensure bearing making smooth advances to power transmission shaft; It is coaxial that fixing structure ensure that between press mold with leading screw, thus can ensure that press mold evenly exerts a force to each portion of bearing, prevents bearing crooked in assembling process; The smooth pivotal that thrust bearing can realize between leading screw with press mold coordinates; Adopting self-aligning thrust roller bearing to be to utilize its adaptation function, ensureing that press mold evenly exerts a force to bearing.
