Description
Technical field
The present invention relates to Automatic manual transmission instrument, especially relate to a kind of portable bearing installing tool.
Background technology
In industrial processes, usually can run into the situation that bearing is assembled on axial workpiece.For example, fill in breaker
Join workshop it is necessary to bearing is installed on the substantial amounts of power transmission shaft in Crankarm box.
Assembling to bearing is initially carried out by the pure craft of manpower, uses workman and is struck along bearing outer ring using "painted-face" character in opera
Hit the mode of bearing, adopt in this way assemble bearing when, due to being localized contact between "painted-face" character in opera and bearing, unbalance stress, very
It is susceptible to the situation of bearing inclination, further, since being manually to tap, inclined situation, this kind of situation are struck in unavoidable occurring
Once occurring, then "painted-face" character in opera will strike on the inner ring of bearing or strike on axle sleeve, if copper strikes on bearing outer ring, tap and produced
Raw power can reach inner ring after the rolling element of bearing again, easily causes the deformation of rolling element, affects the normal use of bearing,
The respective end surface irregularity of axle if "painted-face" character in opera strikes on axle, can be made, affect axle surface quality；Furthermore, installed using tapping
The mode of bearing sometimes there is also the situation that workman knocks hand, easily causes accident.
Presence in view of the above problems, occurs in that the technology installing bearing with hot charge practice and cold charge in industrial production.Cold
Dress method is to put in low temperature environment by axle, for example, put in low temperature liquid nitrogen by axle, and axle is subject to cold events, then takes out dress with instrument
Join bearing, with the rise of temperature, axle expands, completes and bearing fit, and the method is simple, however it is necessary that low temperature liquid nitrogen, low temperature
Liquid nitrogen needs ultralow temperature to preserve, high cost, simultaneously the use of liquid nitrogen, there is also higher safety requirements it is desirable to have strict
Operational procedure, and it is equipped with necessary protective articles.Hot charge practice is first to bearing heating, for example, heat bearing by high temperature spray gun,
Bearing expanded by heating, then on assembly axis, after cooling, bearing shrinks, and completes the cooperation with axle, and the method is also required to high warm
Source, is also uneconomical, less safe method.
Although above two method 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 to be applied in some special fields, it does not have
To being widely popularized.Particularly in field of circuit breakers, because Crankarm box is welded inconvenient movement, implement said method particularly difficult.
Content of the invention
It is an object of the invention to provide a kind of portable bearing installing tool, to solve the power transmission shaft installation axle of Crankarm box
Hold inconvenience, and the flimsy problem in installation process in power transmission shaft and bearing.
In order to solve the above problems, the portable bearing installing tool of the present invention employs the following technical solutions: portable shaft
Hold installation tool, including support, for pushing the press mold of bearing inner race and being used for ordering about the press mold drive that press mold moves along a straight line
Motivation structure, described support includes supporting leg, and one end of supporting leg is provided with for spiral shell on being welded with Crankarm box, being located at around dead eye
The external screw thread of pit cooperation, press mold drive mechanism includes the screw-nut body being assemblied on support, and press mold rolling assembling is in silk
The end of the leading screw of thick stick nut body.
Described press mold has for the endoporus with the power transmission shaft guiding cooperation of Crankarm box.
Felt relieved by fixing structure between described leading screw and press mold and coordinate.
It is provided with thrust bearing between described leading screw and press mold.
Described thrust bearing is self-aligning thrust roller bearing.
When assembling bearing on the portable bearing installing tool using the present invention is to the power transmission shaft of Crankarm box, can be logical first
The external screw thread crossing supporting leg respective end is assemblied on corresponding Crankarm box is welded, and then passes through to drive feed screw nut then to can achieve
Bearing is press-fited, during press-fiting, press mold is fitted with the inner ring of bearing all the time, thus can ensure that each portion of bearing inner race is subject to
Power, uniformly it is ensured that bearing is not damaged by, meanwhile, taps, due to having abandoned, the mode installed, thus also completely eliminating axle
Struck bad possibility.In sum, the portable bearing installing tool of the present invention can be welded with corresponding Crankarm box at any time
It is used together, convenient, flexible, the mode of pressing bearing then substantially increases the installation effectiveness to bearing, reduces to bearing and axle
Destructiveness, the power transmission shaft that the present invention solves Crankarm box installs bearing inconvenience, and in power transmission shaft and bearing in installation process
Flimsy problem.
Further, on press mold, setting and the endoporus of the power transmission shaft cooperation of Crankarm box can ensure bearing to power transmission shaft
Make smooth advances；Fixing structure ensure that coaxial between press mold and leading screw, thus press mold can be ensured, to bearing, each portion uniformly exerts a force,
Prevent bearing crooked in assembling process；Thrust bearing can achieve the smooth pivotal cooperation between leading screw and press mold；Using thrust
Self-aligning roller bearing be in order to using its adaptation function it is ensured that press mold to bearing uniform force.
