Перевод efinitions. a press joint, also called a force joint, is obtained by forcing a shaft into a hole that is slightly smaller than the shaft. this is possible because of the elasticity of the materials which produces the grip that holds the hub and shaft together. a shrink joint differs from a press joint chiefly by the method of assembling it. the hub is heated to expand its bore and to slip it on the shaft. when the hub cools down to the temperature of the shaft, the grip is produced in the same way as in the force joint. the shrink joint is also used to connect machine parts by means of special rings, anchors, and tie rods. in a friction joint the holding grip is produced by the conical shape of the shaft end and the hub bore and by the pull of a nut, or by a slotted hub whose bore is smaller than the shaft and which is spread by a wedge when the joint is being assembled. ii. write out from the text the sentences with verbs in the form of the participle or the gerund or the subjunctive mood.
