Abstract

PURPOSE:To stabilize measured results at the time of correcting the balance of a connecting shaft by giving an unbalance to the connecting section of the connecting shaft and correcting the balance of the shaft outside the connecting section at the time of correcting the balance of the connecting shaft. CONSTITUTION:In the first procedure, unbalance correction is performed on the single body of a propeller shaft 1. The unbalance correction is performed by fitting a balance piece to the shaft 1 so that the unbalanced amount of the shaft 1 can become, for example, 20gcm and the unbalanced direction of the shaft 1 can become the direction connecting the center of the shaft 1 and one bolt hole of a flange 2. In the second procedure, the shaft 1 is fitted to a vehicle after the unbalance of the shaft 1 is corrected. At the time of fitting the shaft 1 to the vehicle together with a differential gear, the gear and shaft 1 are fixed by using mass bolts having masses larger than those of other bolts for the bolt holes on the opposite side of the unbalanced direction by 20gcm.

By the way, since the propeller shaft has looseness due to splines, bearings, etc. at the joint portion (connection portion), the balance changes depending on the direction of the looseness. For this reason, even in the balance correction in the propeller shaft alone and in the vehicle mounted state, the unbalance amount cannot be suppressed to be equal to or less than the unbalance amount generated by the change in the backlash direction. In addition, since the direction of the backlash varies from measurement to measurement, a stable measurement result cannot be obtained, and there is a problem that correction takes time.

The balance correction method of the present invention will be described below with reference to the flowchart of FIG. First, as the first procedure, the imbalance is corrected with the propeller shaft alone. Here, the unbalance amount is 20 gcm, and the balance piece is attached to the propeller shaft so that the unbalance direction is the direction connecting the center of the propeller shaft and the bolt fastening hole of the flange (the direction of arrow A in FIG. 3). By doing so, the imbalance is corrected. Mark on the flange 2 so that the unbalanced direction can be seen on the propeller shaft for which the unbalance correction has been completed.

Next, as a second procedure, the propeller shaft, which has been subjected to the imbalance correction as a single unit, is attached to the vehicle. Here, when mounting the differential gear and the propeller shaft, use a mass bolt with a 20gcm mass larger than other bolts for the bolt fastening hole (B in Fig. 3) on the side opposite to the unbalanced direction. To conclude. As a result, the unbalance of the propeller shaft alone will be canceled by the mass bolt, and the on-the-car unbalance amount will be almost 0 gcm.

As described above, in the above-described embodiment, since the unbalance is left when the unbalance of the propeller shaft is corrected, the backlash direction is always constant. Further, in the vehicle mounted state, the mass bolt is mounted on the flange 2 which is out of the range where there is backlash, so the amount of unbalance between the joint 2A and the joint 3A where backlash exists
Since it is kept at 20gcm, the backlash direction is always kept constant, and the on-the-car unbalance amount does not change. In addition, the unbalance amount was adjusted when adjusting the unbalance of the single unit, and the unbalance direction was set to the bolt mounting hole direction.Therefore, when mounting on a vehicle, the unbalance amount is approximately 0 gcm by using the mass bolt corresponding to the unbalance amount of the single unit. As a result, there is no need for adjustment after mounting on the vehicle body, and workability is improved.
