Abstract
The crank mechanism of the piston compressor comprises individual crank disks (5), which each support on their outer circumference a rolling bearing (6) for the bearing of a connecting rod (4). The crank disks (5) are pressed together to form a package by means of tensioning bolts (7). The crank case (1) is preferably closed off by a case cover (10), the inside of which is formed as a bearing mount for the crank mechanism. Assembly and disassembly of a crank mechanism of this type is particularly simple and efficient and can be undertaken by personnel who are not specially trained. In addition, special relubrication devices provide simple and error free servicing, and thus greater longevity.
