CARTRIDGE ASSEMBLY FOR CATERPILLAR TRACK OF CATERPILLAR WORKING DEVICE AND WORKING DEVICE USING SAID CARTRIDGE ASSEMBLY Russian patent published in 2010 - IPC B62D55/21 

FIELD: transport.

SUBSTANCE: cartridge comprises pin making an axle, rotating sleeve embracing said pin and insert elements arranged on opposite sides of rotating sleeve. Insert elements comprise surface bearing radial load and circular loop arranged about the pin with aforesaid surface and have axial holes. Assembly comprises anti-friction bearings arranged nearby circular loop of insert elements. Anti-friction bearings are arranged partially inside axial opening of said insert elements. Proposed caterpillar-type device comprises caterpillar belt inner link, outer link and cartridge assembly articulating caterpillar links. Anti-friction bearing assy comprises pin, revolving sleeve and insert elements coupled with caterpillar belt inner link. Antifriction bearings are arranged partially between said pin and one of the insert elements. Loop is arranged nearby appropriate antifriction bearing and oriented orthogonal to outer surface of said pin. Method of operation of caterpillar-type device consists in that antifriction bearing representing revolving sleeve is inserted in between inner and outer caterpillar belt links. Cartridge assembly is assembled using slide fit of insert elements, rotating sleeve, first and second antifriction bearings right about said pin. Sleeves are press-fitted on opposite ends of aforesaid pins to allow clamping insert elements, revolving sleeve, first and second antifriction bearings there between.

EFFECT: reduced wear-out.
