摘要： PURPOSE:To shorten the cycle time by temporarily assembling two parts on a pallet by use of movable spacers disposed therebetween, the releasing the spacers by use of a robot after the application of liquid by the robot, and thereafter by assembling both parts under pressure by use of an automatic assembly device. CONSTITUTION:A gear casing (GC) 4 and a ring gear (RG) 5 are set onto a set jig 30 on a pallet P, and a pair of right and left spacers 39 are disposed between the RG 5 and the flange part 4a of the GC 4. Then the RG 5 and the GC 4 are assembled temporarily together with the use of bolts 5, and a thread lock agent is applied to the outer peripheral surface of a bolt 5a and the facing surfaces of the RG 5 and GC 4, automatically by a robot. Then the spacers 39 are moved laterally by means of the robot so as to allow the RG 5 and GC 4 to abut against each other. Then, GC 4 and the RG 5 are pressed by a hydraulic cylinder, a pressing rod and a pressing punch so as to make both in close contact with each other, and thereafter they are assembled together with the use of the bolts 5. Thus, it is possible to eliminate the use of a gap forming device, thereby it is possible to shorten the cycle time.

摘要： PURPOSE:To reduce composite unbalance after assembling by also carrying out the correcting machining of the unbalance of mass not only measuring the unbalance of mass with respect to the rotating center of each assembly. CONSTITUTION:Suppose that there is the unbalance of mass as shown by the vector X as the result of measuring the unbalance of mass with respect to the rotating center P of a propeller shaft assembly 1. By giving correcting machining to this unbalance, a predetermined defined magnitude of a vector Z on a reference angle line (a) which is the closest to the vector X is defined as the target vector after correcting. In this case, as can be seen from the vector chart, by newly producing the unbalance of mass as shown by the vector Y, the composite vector of the vectors X and Y can be made agree with the target vector Z.

摘要： PURPOSE:To perform high-precise regulation of a neutral position by determining a temporary neutral position of the one at a time of an input shaft and a yoke assembly, fixing the one thereof to the position, and driving the other with this state. CONSTITUTION:A stepping motor 75 and an encoder 76 are mounted on a input shaft 26, a displacement gauge 71 is located at the end part of an output rod member 16 to measure a stroke displacement amount of an output rod member 16. The swing angle position of a yaw assembly 18 can be detected by means of a signal from a stepping motor 17. In a microcomputer, regarding the one of an input shaft 26 and the yoke assembly 18, a temporary neutral position is determined. The one is secured to the position, and with this state, the other is driven. Based on the current displacement state of an output rod member 16, correction of neutral position dividing of the one is executed, and thereafter, neutral position dividing of the other is corrected in a similar manner described above.

摘要： PURPOSE:To realize connection between a mechanical system and a hydraulic system without misalignment between them by adjusting neutral position of the mechanical system displacing a rear wheel steering shaft with a displacement transmitting means temporarily assembled, thereafter adjusting and assembling the displacement transmitting means so as to absorb misalignment between neutral positions op the mechanical system and the hydraulic system. CONSTITUTION:When a rear wheel steering device is assembled, adjustment of neutral position of a mechanical system is first performed on the basis of a specified operating condition, with hydraulic pressure not applied. Then, with hydraulic pressure applied, the displacements of a rear wheel steering shaft 13 and a supporting support 38 are respectively measured, and the neutral position of the rear wheel steering shaft 13, at which the rear wheel steering shaft 13 is not displaced even when the supporting support 38 is displace, is detected. Thereafter, with the rear wheel steering shaft 13 located at neutral position, the supporting support 38 which is in a temporarily assembled, is assembled, and the engaging end part C of the cross-shaped lever 14A of a lever-assembly 14 or a displacement transmitting means, is rotatably and unmovably assembled. Thus, the mechanical system and the hydraulic system are connected to each other, and misalignment between the neutral position of the hydraulic system and the neutral position of the mechanical system are absorbed by adjusting the assembling state of the supporting support 38.

摘要： PURPOSE:To facilitate adjustment of neutral position by measuring the displacement of stroke in a period of time when a yoke-assembly for controlling the displacement of stroke of an output rod member turns between two angle positions, and adjustably moving a displacement transmitting means by half the displacement. CONSTITUTION:When the neutral position of a rear wheel steering device l is adjusted, first a yoke-assembly 18 is positioned about at the neutral position, and then a worm 32 is rotated counterclockwise by a stepping motor 17 to rotate the yoke-assembly through a specified angle from about the neutral position to the positive phase side and thus position it at a first angle position, and the stroke-position of a rear wheel steering shaft 13 at this time is measured and stored. Thereafter, the worm 32 is rotated clockwise to turn the yoke-assembly 18 to the opposite phase side and thus position it at a second angle position, the stroke-position of the rear wheel steering shaft 13 at this time is measured and stored, and the total displacement delta of the rear wheel steering shaft 13 is detected. A support 38 is then displaced to displace the rear wheel steering shaft 13 by half the displacement delta, and the support 38 is then assembled.

摘要： PURPOSE:To enable the easy exchange of taps with different leads by enabling the taps to absorb an advance speed difference between a drive unit and the taps via the rotational engagement means of the taps and a main spindle coupled to the main spindle for free slide in an axial direction via an elastic body. CONSTITUTION:The rotation axis part 66 of the first main spindle 56 is made to have a boss part 72 in a right and left direction with a large diameter at the right end part 70 thereof and six rows of grooves formed in the hollow part, and the right edge of the rotational axis part 66 is provided with a hole of the same diameter as the spindle diameter of a tap mounting jig part 68. The tap mounting jig part 68 is fixed to a chuck 74 for mounting a tap 62 and the left end part 78 of the axis 66 is formed to have a spline shaft 78 for engagement with the boss part 72, so that the rotational axis part 66 and the tap mounting jig part 68 are in rotational engagement and freely slidable with each other. A coil spring 80 is extended between the left edges of the spline shaft 78 and the boss part 72. And the spline shaft 78 is positioned approximately at the center of the boss part 72 in the natural length of the spring 80. When the spline shaft 78 slides in a left direction with the boss part 72, the tap 62 is subjected to a pressing force in a right direction. A force in a left direction works upon the tap 62 when the spline 78 slides in a right direction with the boss part 72. The same applies to the second main spindle 58.
