Problems solved by technology

When pressing the bearing in this method, since the fit between the crankshaft and the bearing is an interference fit, it needs to be pressed with a pressure of about 3000N on the press, and the crankshaft is an eccentric crank throw part. It is easy to deform at the crank of the crankshaft, which affects the quality of the crankshaft

Abstract

The present invention relates to a method for press-mounting bearing on crankshaft. Said method includes the following steps: firstly, fixing the crankshaft on a supporting frame; then making the bearing to be mounted by cover-placed on the upper side of mounting portion of said crankshaft and making axis of bearing be coincident with axis of said crankshaft; in the notch position of said crankshaft placing a pusher along the axial direction of said crankshaft and making two end portions of pusher be respectively tightly contacted with first main shaft neck and second main shaft neck; finally applying pressure to said bearing until the described bearing is fixed on the mounting portion of said crankshaft.

Description

technical field [0001] The invention relates to a method for press-fitting a bearing on a crankshaft, which is mainly used on a loom. Background technique [0002] The crankshaft is an important part of the loom, and the quality of the crankshaft will directly affect the performance of the loom. The crankshaft generally includes a first main shaft and a second main shaft arranged at both ends, a first main journal connecting the first main shaft and the second main shaft, and a second main journal connecting the first main journal and the second main journal and deviated from the axis center of the crankshaft The crank throw set by the line, so as to form the gap between the first main journal, the second main journal and the crank throw. The traditional press-fitting method is to place the crankshaft on the support frame, and place the bearing at the position to be pressed for press-fitting . When pressing the bearing in this method, because the fit between the crankshaft...
