PURPOSE:To automate appropriate affording of a thrust pre-pressure to the universal joint by affording the thrust pressure to the universal joint, and measuring the swinging resistance to discriminate the thrust pre-pressure. CONSTITUTION:An engaging metal fitting 8 is meshed with the other yoke 2b of the universal joint 1 afforded with a thrust pre-pressure by pressing means, and a leaf spring 9 is swung by a swinging angle of 25 deg. in one direction by a hyraulic cylinder 10 for swinging. Upon this occasion, the quantity of strain generated in the leaf spring 9 is detected by a strain sensor 17 and further amplified by an amplifier 18 and introduced into a comparison discriminator 19. When the swinging resistance is discriminated to be unsuitable, a controller 21 issues an instruction to a variable type pressure drive source 22, and application of pressure with respect to the universal joint 1 is resumed by pressure application means 23. |
