摘要： One-way clutch 18 has a spring the elastic modulus of which is limited up to a predetermined value, seal rings 36a, 36b have a sliding resistance with respect to the inner rings 22 which is limited up to a predetermined value, and support bearings 17a, 17b have a rotation resistance which is limited up to a predetermined value. The torque required to rotate the driven pulley 7a relative to the sleeve 8a in the direction for overrun condition is limited up to 0.5N·m. Accordingly, the power generating efficiency of the alternator is secured while abnormal sounds are prevented from occurring with the life of endless belt being prevented from reducing.

摘要： Outer peripheral portions of magnetizing terminals 39a constituting a magnetizing apparatus 33a for magnetizing a permanent magnet 32, are made longer than inner peripheral portions. Coils 40 for magnetization are wound around the shorter length inner peripheral portions. A distance L32 between the magnetizing terminals 39a and a step portion 37 of a support ring 34 can thus be shortened, so that the axial length of the encoder 31a can be reduced. This results in reducing the axial length of an encoder 31a to thereby miniaturize and lighten a speed sensing rolling bearing unit incorporating the encoder 31a.

摘要： A rolling-bearing unit including a stationary ring, a rotating ring, an annular magnetic tone wheel having a cutout section with cutouts formed at equal intervals at a pitch, and a sensor facing the tone wheel. The sensor comprises a pair of annular or cylindrical permanent magnets arranged concentric with the tone wheel, an annular or cylindrical stator of magnetic material magnetically connected with the permanent magnets and provided concentric with the tone wheel, and an annular or cylindrical coil provided concentric with the tone wheel and proximate a central portion of the stator. Like magnetic poles of the pair of permanent magnets are magnetically connected to opposite ends of the stator. Peripheral faces of either the magnets or ring portions of the stator are formed with alternating recesses and protrusions with the same pitch as in the cutout section of the tone wheel and facing the cutout section of the tone wheel. The phase of the alternating recesses and protrusions of the peripheral face at one axial end of the stator relative to the cutout section is displaced by one half from the phase of the recesses and protrusions of the peripheral face at the other axial end of the stator relative to the cutout section.
