Abstract
Urządzenie do nagniatania powierzchni wewnętrznych cylindrów siłowników hydraulicznych charakteryzuje się tym, że zbudowane jest z wału napędowego (6), na którego końcówce osadzona jest wirująca oprawa (3) zamknięta pokrywą (7) z luźno umieszczonymi co najmniej dwoma bijakami (1) z końcówkami roboczymi (2), które na pobocznicy posiadają nacięcia w postaci spiralnych rowków, natomiast przestrzeń pod bijakami (1) napełniana jest cieczą chłodząco - smarującą (10) pełniącą funkcję sprężyny hydraulicznej, poprzez otwory (5) wykonane w pierścieniach (4 i 4a) pod bijakami (1).The device for burnishing internal surfaces of cylinders of hydraulic cylinders is characterized by the fact that it is made of a drive shaft (6), on the end of which a rotating housing (3) closed with a cover (7) with loosely located at least two beaters (1) with working ends is mounted. (2), which have incisions in the side surface in the form of spiral grooves, while the space under the beaters (1) is filled with a cooling-lubricating liquid (10) acting as a hydraulic spring, through the holes (5) made in the rings (4 and 4a) under the beaters (1).
