Embodiment Construction

[0011] Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in further detail:

[0012] As shown in the figure, the marine door lowering reducer includes a box body 1, and a first input shaft 2, a second input shaft 3, an intermediate shaft 4 and an output shaft 5 are supported by bearings in the box body 1. The first input shaft 2 is a worm shaft, the second input shaft 3 is a pinion shaft, the second input shaft 3 is parallel to the intermediate shaft 4 and the output shaft 5 , and the first input shaft 2 is perpendicular to the intermediate shaft 4 . The input end of the first input shaft 2 is processed with an axial connection inner hole 6, and a keyway is processed in the connection inner hole. A flange 7 is installed on the outer casing of the protruding end of the first input shaft 2, and the flange 7 is used for the installation of the input motor, and a sealing ring is installed between the inner ring of the fla...

Abstract

The invention relates to the field of speed reducers, and provides a door descending speed reducer for a ship. Two input modes of worm and gear transmission and planetary transmission are achieved, two input shafts are perpendicular to each other, a proper input mode can be conveniently selected on site, worm and gear input can be used as manual input, meanwhile, self-locking during power failurecan be guaranteed, and safety accidents are avoided. By designing a planet carrier gear, the two transmission modes are combined together, the structure is compact, two-speed-ratio lifting is achievedthrough the double input, and the safety coefficient is high.

Description

technical field [0001] The invention relates to the field of speed reducers, in particular to a marine door drop speed reducer. Background technique [0002] The doors on ships are generally steel structures, and the door leaves in some positions are relatively large in size and weight. The opening of the door leaf usually requires the drive of the reducer. For lift-type doors, if the power is suddenly cut off or the reducer fails during the lifting process, the door leaf will fall easily and a safety accident will occur. The locking mechanism installed on some reducers solves the problem of the door leaf falling, but the door leaf cannot be opened or closed in a fixed position. Contents of the invention [0003] In order to solve the potential safety hazards caused by power failure and other problems in the opening or closing process of the marine door leaf in the prior art and the defect that it cannot continue to work in the case of power failure caused by single inpu...
