摘要： A crankshaft of an in-line, four-cylinder internal combustion engine has five journal portions. The journal portions are each supported by a main bearing unit. Each of the main bearing units includes a cylinder block side bearing part and a bearing cap. The No. 1, No. 2, No. 4 and No. 5 main bearing units employ an iron-based bearing cap, and the No. 3 main bearing unit at the center employs a bearing cap made of an aluminum alloy having a relatively high thermal expansion coefficient. At high temperatures, the bearing clearance of the No. 3 main bearing unit is configured to expand so as to reduce bearing load.

摘要： The compressor comprises: a crankcase (10) carrying a cylinder (20) and a bearing hub (40) having a first and a second end portions (40a, 40b) and defining a radial bearing (41), in which is housed a crankshaft (50); and a connecting rod (60) coupled to a piston (30) housed in the cylinder (20) and having a larger eye (61) mounted in an eccentric end portion (55) of the crankshaft (50). Each of said end portions (40a, 40b) is defined by a bushing extension (45, 46) affixed in the interior of the bearing hub (40) and having an end portion (45a, 46a) projecting outwards from the bearing hub (40), in order to be elastically and radially deformed when pressed by a confronting portion of the crankshaft (50), which presents coaxiality deviation in relation to the axis (X1) of the radial bearing (41).

摘要： A crankshaft bearing for internal-combustion engines is provided in an internal-combustion engine housing made of a light metal alloy and comprises a bearing bore for a crankshaft journal of a crankshaft. The crankshaft bearing is provided with a device that reduces the increase in bearing play that occurs during the operation of the internal-combustion engine. This device includes a compensating element which is provided between the bearing bore and the crankshaft journal and has a relatively high coefficient of expansion.

摘要： The invention relates to a method for producing and/or assembling a bearing with a bearing bore, a journal which is located in the bearing bore and at least two bearing shells which at least partially encompass the journal in the bearing bore, there being a number n of tolerance classes. Here the bearing class width C1 for the bearing bore and/or the journal should obey a relation C1=T1=t2=T3= . . . =tn/Tn, and another bearing class width C2 for at least the first of the bearing shells and/or at least one other of the bearing shells should follow the relation C2=t1=T2=t3= . . . =Tn, Ti (with i=1, . . . , n) being tolerance range values of the bearing bore and/or of the journal and ti (with i=1, . . . , n) being tolerance range values of at least one first and/or of at least one other bearing shell and that the bearing bore is assigned to one bearing shell and/or the journal is assigned to the other bearing shell such that there is the same bearing classification with C1=C2 and/or an unlike bearing classification with C1 C2, preferably C1>C2. The invention furthermore relates to a bearing.
