Seal for transmission with mechatronic system
PATENTS Seal for transmission with mechatronic system
Inner seal for CV joint boot Applicants/Inventors: D. Dao et al. (Canada) During use of a CV joint it is possible for some lubricant to migrate out from the bearing to the interior of the CV joint boot. It is possible for the lubricant to overstress the boot at high rotational speed. This patent describes a way of inhibiting the migration
of bearing lubricant during use of the CV joint. An inner shield is fitted inside the boot assembly that seals between the bearing and the boot to inhibit migration of the grease from the bearing. Patent number: WO 2006/133550 Publication date: 21 December 2006
Applicant: ZF Friedrichshafen AG, Germany The invention relates to a seal for an automatic transmission with a mechatronic system which includes an electronic module and an electrohydraulic switching device. The
Lip type seal Applicant: NOK Corporation, Japan A plastic lip type seal is described that is designed to be capable of increasing safety against rupture by reducing the rigidity of a plate-like lip bent about the tip point A. The wedge-shaped recess reduces the stress concentration at the point A, suppressing the reduction of sealability due to a reduction in the creep of
Patent WO 2006/133550 describes a CV joint boot fitted with an inner shield to inhibit migration of grease from the bearing into the boot.
Circumferential machining is also discussed. Patent number: WO 2006/135085 Inventors: O. Kubota, T. Yui and H. Furukawa Publication date: 21 December 2006
Ellipsoid roller bearing piston ring Applicant/Inventor: A.R. Williams (USA) This patent describes a piston ring that is designed to reduce friction and hence improve engine performance. A series of elongated rollers, which may be elliptical in profile, are arranged around the
the lip. It also increases the follow-up capability of the lip to any eccentricity. A variety of arrangements for the serrations, that may be on either the static or dynamic surfaces are also described. Patent number: WO 2006/134756 Inventors: Y. Kondo et al. Publication date: 21 December 2006
The plastic lip seal design with a stress reducing recess, from WO 2006/134756.
High-pressure seal for fuel injection valve Applicant: Bosch Corporation, Japan A high-pressure seal design for fuel injectors is described. The mating flange faces are machined with a concave geometry so that initial contact is at the outside diameters.
elastomeric seal is inserted between the electronic module and the actuator and/or sensor. Patent number: WO 2006/133817 Inventor: N. Hoersch Publication date: 21 December 2006
Mechanical seal Applicant: Eagle Industry Co Ltd, Japan This patent describes a compact stationary metal bellows seal with external rotating face but also includes an illustration of a
stationary floating element seal with external springs. Patent number: WO 2006/137305 Inventor: H. Takahashi Publication date: 28 December 2006

on an O-ring or similar flexible mount. This permits some shaft movement as for example if there is bending of a pump shaft during operation. Patent number: WO 2006/137766 Inventor: J. Zebrowski Publication date: 28 December 2006
Adjustable gas delivery mask with flexible gasket Applicant: Nellcor Puritan Bennett Inc, USA This patent describes a mask for the provision of continuous positive airway pressure (CPAP) therapy to a patient who may be suffering from a breathing ailment while sleeping. This
mask has a particularly flexible gasket that overcomes leakage problems that occur due to the wide variety of face and head sizes and shapes. Patent number: WO 2006/138346 Inventors: E.M. Geiselhart et al. Publication date: 28 December 2006 13
