474190000 | Including nonmetallic belt-engaging surface portion | 6 |
20100184548 | INJECTION MOLDED PULLEYS HAVING LOW LEVELS OF OUT-OF-ROUNDNESS - Injection molded plastic pulleys ( | 07-22-2010 |
20120094796 | RESIN PULLEY - A resin pulley includes an outer cylindrical portion including an outer circumferential surface on which a belt is to be wound, an inner cylindrical portion, and a plurality of ribs connecting an inner circumferential surface of the outer cylindrical portion and an outer circumferential surface of the inner cylindrical portion, which are formed of a resin material. The ribs are provided so as to be inclined towards a circumferential direction relative to a radial imaginary line as viewed in an axial direction. Radially outer end portions of the ribs are formed such that inclination angles of the respective radially outer end portions relative to the radial imaginary line increase as the ribs extend radially outward, and radially inner end portions of the ribs are formed such that inclination angles of the respective radially inner end portions relative to the radial imaginary line increase as the ribs extend radially inward. | 04-19-2012 |
20140221140 | PLASTIC PULLEY FOR DRIVING DRUM FOR WASHING MACHINE INTO ROTATION - A pulley comprising: a central hub; a peripheral crown; a first intermediate section comprising a plurality of radial ribs that radially extend from the hub, and a second intermediate section comprising a plurality of peripheral ribs that end into the peripheral crown and intermediate circular rib concentric with the center of the pulley and having a radius basically equal to half radius of the pulley, the circular intermediate rib separating the first intermediate section from the second intermediate section, the circular intermediate rib comprising connection points of radial ribs and of peripheral ribs, wherein the connection points of radial ribs are distant from those of the peripheral ribs; the peripheral ribs being suitably inclined mutually and with respect to the radial ribs in such way to intersect at least in one crossing point to form a web structure in the second intermediate section. | 08-07-2014 |
20140296010 | FRICTION DRIVE BELT AND MANUFACTURING METHOD THEREFOR - In order to allow a friction drive belt to have an effect of reducing slip noise produced between the belt and pulleys for a long period even when the belt gets wet with water or suffers from wearing out, a V-ribbed belt B as the friction drive belt includes a belt body | 10-02-2014 |
