Timing gears press-fiting on bent axle operated as follows:
Earlier timing gears are put into the gear locating hole of gland, and the tooth at place, timing marks place on the timing gears is meshed with the tooth card, thereby finish the location of timing gears in press-fiting cover.
Afterwards, the crankshaft output end that is pressed with woodruff key is inserted in timing gears centre bore and the positioning sleeve successively, and the woodruff key of crankshaft end is entered in the locating slot of positioning sleeve, thereby finish the location of bent axle in press-fiting cover.
Bent axle is placed on the workbench of press together with press-fiting cover, step on motivation bed switch pedal, the lathe pressure head press press-fit the cover descending, because bent axle can not be descending on the workbench of press, the crankshaft output end that then is pressed with woodruff key upwards slides (the compression spring is compressed) with respect to pressure cylinder in pressure cylinder with positioning sleeve, thereby timing gears are fitted on the bent axle.
After treating the up return of lathe pressure head, the two ends of with the hands holding driving lever upwards promote driving lever, driving lever will drive positioning sleeve and upwards slide in pressure cylinder, positioning sleeve is separated with bent axle, just bent axle can be taken out from press-fit cover then, positioning sleeve is return under the compression spring action then, is pressed on the upper surface of gland again, thereby finishes timing gears press-fiting on bent axle.
Utilize and described in the utility modelly press-fit cover and carry out press-fiting of timing gears, timing gears and bent axle are in that to press-fit the location that puts convenient and reliable, timing gears can not produce displacement when press-fiting, press-fit the qualification rate height, can reach 100%, and press-fit simple to operationly, only need a people to finish and press-fit operation.
