  • Protective cover for universal joint seal boot
    Patent number: 5312300
    Abstract: A drive shaft assembly has universal joints at each end that include flexible seal boots. The drive shaft assembly has a protective cover for the flexible seal boots in the form of a seamless woven nylon sleeve that is clamped onto the universal joint housings at each end of the drive shaft. The sleeve is tied in the middle to reduce its profile. Alternatively, the drive shaft assembly may have an individual protective cover for each flexible seal boot. These individual protective covers are also in the form of a seamless woven nylon sleeve. But these individual sleeves have a conical portion that terminates in a small diameter opening that closely surrounds the drive shaft.
