Structural features and technical requirements of sleeve parts
Publisher: Webmaster | release time:2013/6/25 |read:1852Times
    The sleeves Precision parts are divided according to the structural characteristics: there are various bearing rings and shaft sleeves that support the rotating body, drill sleeves and guide sleeves on the fixture, and cylinders on the internal combustion engine Sleeves, hydraulic cylinders in hydraulic systems, valve sleeves for electro-hydraulic servo valves, cooling sleeves in electric spindles, etc.
    1. Structural characteristics of sets of parts
   The structure and size of the sleeve parts vary with different uses, but the structure generally has the following characteristics:
    1) The diameter d of the outer circle is generally smaller than its length L, usually L/d<5.
    2) The difference between the diameter of the inner hole and the outer circle is small.
   3) The coaxiality of the inner and outer circular surfaces must be high.
    4) The structure is relatively simple.
