BOOT FOR CONSTANT VELOCITY JOINT AND CROSS GROUP-TYPE CONSTANT VELOCITY JOINT |
摘要 |
<p>A boot for constant-velocity universal joint comprises a major-diameter cylindrical portion 2, a minor-diameter cylindrical portion 3 being separated away from and being put in place concentrically with the major-diameter cylinder portion 2, and having a smaller diameter than that of the maj or-diameter cylindrical portion 2, and an intermediate portion 10 connecting the major-diameter cylindrical portion 2 with the minor-diameter cylindrical portion 3. The intermediate portion 10 comprises a stretchable bellows portion 19 being connected with the minor-diameter cylindrical portion 3 integrally, and a rigidity-producing portion 11 being connected with the bellows portion 19 and the major-diameter cylindrical portion 2 integrally. The rigidity-producing portion 11 enlarges diametrically from the bellows portion 19 toward the major-diameter cylindrical portion 2, and additionally at least an outer peripheral surface 101 of the rigidity-producing portion 11 has a plurality of shoulders 61 in a stepwise manner. By means of the rigidity-producing portion 11, the rigidity at around the major-diameter cylindrical portion is enhanced, and thereby it is possible to suppress deformation at the time of assembling.</p> |
