Мақолада Д-240 ички ёнув двигатели тақсимлаш вали кулачоклари профилининг ташкил этувчи қисмлари, кулачок профили ва турткич гильзасидан иборат бўлган ишқаланиш жуфтлигига қўйилган талаблар ҳамда уларнинг конструктив хусусиятлари таҳлил қилинган. Киритиш ва чиқариш кулачок профилларининг ташкил этувчи қисмлари ўлчамлари ҳамда уларнинг хусусий жиҳатлари ўрганилган. Кулачок ва турткич гильзасидан тузилган ишқаланиш узелининг туташув кенглиги ва майдони, сирпаниш даражаси ҳамда мойли муҳитда ишловчи киритиш ва чиқариш кулачок профилининг ейилиш тезлиги, ишқаланиш сиртларининг ғадир-будурлик кўрсаткичлари ҳамда ишқаланиш узели орасидаги мой пардасининг қалинлигини назарда тутувчи ҳисоблаш услубиятлари ишлаб чиқилган. Кулачок профиллари ейилиш тезлигига таъсир кўрсатувчи нормал юклама, уларнинг бурчак тезлиги, сирпаниш даражаси, туташув кенглиги, материалининг оқиш чегарасига боғлиқлигини аниқлаш имконини берувчи аналитик боғланишлар келтириб чиқарилган.
