Abstract

PURPOSE:To facilitate the fitting-in of a nut anti-rotation pin and obtain enough clamping torque, by adjusting the position of a clamping nut to a pin hole while inching the nut in additional clamping at high torque after clamping at low torque. CONSTITUTION:High-pressure air from an air source 11 is divided to a high and a low pressure air regulators 12, 13 connected to a control valve 14. First a shutoff valve 15 is opened and a push button 16 is switched off to turn a nut runner 10 through the regulator 12 to perform clamping at low torque. The push button 16 is thereafter switched on to turn the nut runner 10 through the regulator 13 to perform clamping at high torque. In this work, a nut 4 is stopped just in front of the pin hole 7 of a drive shaft 1 and then inched in a direction for additional clamping so that the position of the nut is adjusted to a hole for a nut anti-rotation pin 6.

As shown in Fig. 1, a pair of drive shafts 1 are attached to the left and right sides of the drive differential 2, and wheel hub anchors 3 and the like are fastened to each side end of the drive shaft 1. As shown in FIG. 2, the end of the drive shaft 1 is provided with a threaded portion 5 of a nut 4 and a pin hole 7 of a nut locking pin 6. After fixing the nut, the nut rotation stopper 6 is attached to the drive shaft 1.
It is fixed by fitting it into the pin hole 7.

である。However, in conventional assembly work, in order to insert the lock pin 6 for rotating the nut into the pin hole 7 of the drive shaft 1, it is difficult to align the locking groove of the nut 4 with the pin hole 7 of the drive shaft 1. In other words, if the nut 4 is tightened too much, it will not be able to rotate and the holes will not match up, so the worker must tighten the nut in the loosening direction, giving priority to hole alignment, resulting in insufficient tightening torque for the nut, etc. 9 in the figure is a shaft & joint assembly.

When assembling and fixing the wheel hub assembly to the end of the drive shaft, while moving it in the direction of increasing the Nand's supply,
This provides a method for tightening a drive shaft with the aim of making it easy to align the pin hole of the drive shaft and the loose groove of the oak, etc., and to obtain sufficient tightening (= J chipping). O Hereinafter, embodiments according to the present invention will be explained in detail based on FIGS. 3 and 4. FIG. 3 is an exploded perspective view showing the main parts of the drive shaft 1 according to the present invention, and is different from the conventional structure. Z), which will be explained with the same reference numerals. In the figure, 1 is a drive shaft, a 4-piece tightening nut, 5 is a screw portion of the drive shaft 1, a 6-piece nut rotation stopper pin, and a pin hole of the 7-piece drive shaft 1.
