Example Embodiment

[0021] Example one:

[0022] Figure 2 shows the method of mounting a bearing on the crankshaft in the first embodiment, which includes the following steps:

[0023] (a) Fix the crankshaft 11 on the support frame 1. The support frame 1 is provided with a mounting hole 13, and the second main shaft 16 of the crankshaft 11 penetrates the mounting hole 13 and makes the The second main journal 3 of the crankshaft 11 is fixedly erected on the upper mouth of the mounting hole 13;

[0024] (b) Set the bearing 7 to be installed on the upper side of the mounting portion of the crankshaft 11 and make the axis line of the bearing 7 coincide with the axis line 9 of the crankshaft 11; A jack 10 is placed at the vacant portion 2 of the crankshaft 11 along the axis 9 of the crankshaft 11. The jack 10 includes a bolt 5 and a screw threaded on the screw 51 of the bolt 5. Cap 6, the bolt 5 abuts against the upper end surface of the second main journal 3, the nut 6 abuts against the lower end surface...

Example Embodiment

[0026] Embodiment two:

[0027] Figure 3 shows the method for mounting a bearing on the crankshaft in the second embodiment, which includes the following steps:

[0028] (a) Fix the crankshaft 11 on the support frame 1. The support frame 1 is provided with a mounting hole 13, and the second main shaft 16 of the crankshaft 11 penetrates the mounting hole 13 and makes the The second main journal 3 of the crankshaft 11 is fixedly erected on the upper mouth of the mounting hole 13;

[0029] (b) Set the bearing 7 to be installed on the upper side of the mounting portion of the crankshaft 11 and make the axis line of the bearing 7 coincide with the axis line 9 of the crankshaft 11; A jack 10 is placed at the vacancy 2 of the crankshaft 11 along the axis 9 direction of the crankshaft 11. The jack 10 includes a screw 19 and a nut threadedly connected to the lower end of the screw 19 18. The top cap 20 fixedly sleeved on the upper end of the screw 19, the top cap 20 abuts against the lower...

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...
