In: Research in Agricultural engineering, Czech Academy of Agricultural Scienses, Institute of Agricultural and Food Information, 49, 2003 (1), s. 27-31, ISSN 1212-9151 Abstract: Several techniques are at disposal for production or repair of internal threads. The repair of threads by means of flexible thread inserts and the repair of threads by means of sold thin walled thread inserts belong to the most important ways. The properties of threads repaired using flexible and solid thin-walled thread inserts were experimentally verified and compared. Laboratory comparison of loading capacity of the threads according to observance of specified technological procedures was carried out. Durability and reliability of the repaired threads were verified in operation, while the threads endured long-time variable mechanical and temperature load.
