Track traffic gear-box driven gear is installed on the rail traffic vehicles axletree, plays the effect that drives the axletree running.Along with the continuous development of rail traffic vehicles to high speed, heavily loaded direction, reliability and the security requirement of vehicle operating improve constantly, therefore the position accuracy demand that driven gear is installed on the axletree just progressively improves, and needs the special assembly tool of design to guarantee its installation accuracy.
The assembling of current track transport gear case driven gear and axletree mainly contains hot jacket, colds pressing, oiling press-fits modes such as (being primarily aimed at band tapering axle).Colding pressing press-fits plurality of devices such as needing press, oil pump with oiling, and required frock is many, and the cost input ratio is bigger.Compare with these two kinds of assembling modes, the hot jacket assembling mode is convenient and swift, and required tooling device is few, and cost is low, therefore, and track traffic gear-box driven gear and the axletree assembling hot jacket assembling modes that adopt more.
When adopting the hot jacket assembling mode, driven gear is nested into axletree in the driven gear wheel hub, and sets upright by oiling after heating, and driven gear installation site and precision guarantee by tool locating.Assembly tool adopts the axle shaft end locate mode more in the driven gear assembling in the past, this locate mode needs the extra spacer pad of making, and the gear installation accuracy is subjected to assembling to bear a plurality of parts such as platform, gear positioning tool, spacer pad, axletree end face precision easily to be influenced, installation accuracy is difficult for guaranteeing and control that tool structure is complicated.In a single day and find that the driven gear installation site is inaccurate, and adjust relatively difficulty again, need expend the plenty of time, influence production efficiency easily.
Summary of the invention
The purpose of this utility model is to provide a kind of can guarantee driven gear installation site precision, and track traffic gear-box driven gear assembly tool easy to use.
In order to achieve the above object, the technical solution of the utility model is: a kind of track traffic gear-box driven gear assembly tool, comprise that assembling positioning table and assembling bear platform, has mesopore on the described assembling positioning table, stopping step, locating table and positioning step, described stopping step is positioned at the top of assembling positioning table, locating table is the step surface that is positioned at assembling positioning table periphery bottom, positioning step is positioned at the bottom of the mesopore of assembling positioning table, the upper surface of positioning step is plane of orientation, described assembling is born platform and is had pedestal and platform, have a hole and stop table top on the pedestal, described stop table top is positioned at the end face that platform is born in assembling, platform is positioned at the bottom that platform is born in assembling, the bottom of described assembling positioning table is inserted into assembling and bears in the seat hole of platform, and the locating table of assembling positioning table places assembling to bear on the stop table top of platform.
Have two the first lifting hole(eyelet)s radially on the described assembling positioning table, described assembling is born has two second lifting eyes radially on the platform.Lifting hole(eyelet) is set can connects the screw etc. of slinging, can utilize the lifting machine will assemble positioning table and assembling and bear the platform movement of slinging, convenient use alleviates user of service's labour intensity.
Pedestal and assembling positioning table that platform is born in described assembling are cylindric.Cylindric axletree centering can be convenient to gear location and hot jacket the time.
After adopting said structure, when driven gear and axletree assembling, earlier driven gear is heated, make the expansion of rising of gear hub diameter heat, after heating reaches uniform temperature, treat that the gear hub diameter expands prescribed limit to, rapidly driven gear is placed on the assembling positioning table in the utility model, be nested in the driven gear wheel bore after then axletree being sling, after treating the positioning step applying on the assembling positioning table in the axletree shaft shoulder and the utility model, axletree stops to fall, and then sets upright by oil filler point oiling on the driven gear.Namely fit with the positioning step of assembling positioning table by the axletree shaft shoulder and position in the installation site of driven gear.
The utility model has changed the axle shaft end locate mode of in the past using always, need not additionally to make the axle head spacer pad, and adopts its ratio of precision axletree end face locating accuracy height of axletree shaft shoulder plane positioning, has improved driven gear installation site precision.
In addition, the utility model also has simple in structure, and is easy to use, and cost is low, easily the characteristics of making.
