Abstract: Disclosed is a crosshead component of a large diesel engine. The crosshead component consists of a crosshead pin (1), slide blocks (2), wear-resisting plates (3), sealing covers (4), and a sleeve (5), and has a structure with H-shaped cross and longitudinal sections. The crosshead pin (1) is a cylinder provided with petal-shaped through holes. The slide blocks (2) are respectively fitted on and connected to outer circles of left and right ends of the crosshead pin (1). The sleeve (5) is inserted in and connected to the petal-shaped through holes (112) of the crosshead pin (1) to form oil inlet/return way cavities. Left and right end surfaces of the crosshead pin (1) are respectively connected to the sealing covers (4) for sealing the oil way cavities. Front and back ends of the slide blocks (2) are respectively connected to the wear-resisting plates (3). The crosshead component has excellent interchangeability, economy and convenience.

Abstract: A pressure-resistant hull for a submersible, includes unit hulls, reinforcing ribs, connecting channels, and closure heads. A plurality of unit hulls are provided, and are sequentially strung together spiralling upward or spiralling downward, the closure heads being arranged on the unit hulls at the first position and the last position respectively, an observation window being provided on each unit hull respectively, adjacent two unit hulls in a horizontal direction being respectively connected by means of a reinforcing rib, and at least two connecting channels being provided between adjacent two rings of the unit hulls in the vertical direction. The design method includes using a spiral joining structure to facilitate organic adjustment of the number of unit hulls, thus having better utilization of space and aiding to greatly expand the space. The sensitivity of the limit load to defects is low, increasing axial rigidity, improving the overall pressure-resistive ability.
