Description

Известен способ разборки прессовых соединений деталей типа вал-втулка, включающий операции нагрева соединени  до заданной температуры и охлаждени  его до темлератуфы окр жаю-щей среды ic последующим съемом обхватывающей детали. Однако способ не обеспечивает разборку тонкостенной обхватывающей детали с валом.There is a known method of disassembling press joints of parts such as a shaft hub, including the operation of heating the joint to a predetermined temperature and cooling it to temleratums of the surrounding medium ic, followed by removal of the gripping part. However, the method does not provide for disassembly of a thin-walled clutch piece with the shaft.

По .предлагаемому способу в цел х устранени  указанного недостатка соединение охлаждают со скоростью град/сек.According to the proposed method, in order to eliminate this drawback, the compound is cooled at a rate of deg / sec.

Способ за1ключаетс  в следующем.The method is as follows.

Hainperoe соединение охлаждают в калгере со средней скоростью град/сек (путем струйного опрыскиваии  соеди1неН1И  хладагентом ).Hainperoe compound is cooled in the calgers at an average rate of degrees / sec (by spraying with a non-refrigerant compound).

При иатреве в соединении деталей как с различным коэффициентом линейного расширеди  вала и втулки, та.к и с ад-и-наковым коэффициентом ваЗНИкает те лшературный нат г. При охлаждении обхватывающа  товкостел .на  деталь, быстрее .вала, создает в соединении донолнигельный температурный .нат т, который, суммиру сь с температурНЫМ нат гом при иагреве и расчетным .нат гом в соединении, превышает ма1К1СИмально допустимый нат г. В результате происходит остаточнам пластическа  деформаци  тонкостепной обхватывающей детали, напрп.мер удлинител  .вала электродвигател , и расчет ый нат г изза см ти  исчезает. После полного охлаждени  вала обхватывающа  тонкостенна  деталь без усили  легко снимаетс .When connecting to parts, as with a different linear expansion coefficient of the shaft and sleeve, as well as with an ad-and-nak coefficient, it takes up the spec. Nat. t, which, summing up with the temperature stress during heating and the calculated intake in the joint, exceeds the maximum allowable tension, y. As a result, residual plastic deformation of the fine-grained wrap part occurs, eg extender .vala motor, and the calculation of the first tension due g creasing disappears. After the shaft has completely cooled, the thin-walled, thin-walled part is easily removed without effort.

Предлагаемый способ обеспечивает разборку соединений тонкостенна  втулжа-вал при различных значени х н «хд.т, где а - коэффициент линейного расширени . Он поз0 вол ет производить за-.мену, в частности, удлинителей при ремонте электродвигателей без .повреждени  вала. Способ отличаетс  простотой , высо;кой эффективностью, возможностью The proposed method provides for disassembling the thin-walled sleeve-shaft connections at various values of n & ht, where a is the linear expansion coefficient. It allows one to replace, in particular, extension cords when repairing electric motors without shaft damage. The method is characterized by simplicity, high efficiency, possibility
