Description

Gear copper bush pressing auxiliary tool

Technical Field

The utility model belongs to the technical field of gear machining, concretely relates to utensil is assisted to gear pressure copper sheathing.

Background

The gear and the copper sleeve outer ring are connected through interference fit, and the copper sleeve and the output shaft must be in clearance fit, so that the shape and the size of the inner hole after the copper sleeve is pressed are especially important to control. The press fitting of the copper bush is mainly completed by an oil press at present domestically, and the magnitude of press-in force in the press-in process cannot be monitored. During press mounting, if the magnitude of interference between the outer ring of the copper sleeve and the hub aperture is too large, the pressing force is increased, and excessive extrusion in the press mounting process causes the size of the inner hole of the copper sleeve to be reduced and the inner hole to be deformed, so that the service life of the gear is shortened, and even the gear cannot work normally; if the interference magnitude is too small, the copper sleeve is possibly separated from the gear in the working process, so that a series of safety hidden ranges are formed.
