Nonstandard crowned tooth coupling

Abstract

The invention provides a nonstandard crowned tooth coupling which mainly comprises a left external tooth, a left seal ring, a left internal tooth, a right internal tooth, an oil cup, an end face seal ring, an end cover, a right seal ring, a right external tooth, a screw, a washer, a bolt, an elastic cushion and a nut, wherein inner holes of the left external tooth and the right external tooth are provided with key slots; threaded holes are distributed in the right end face of the external tooth; the left external tooth is meshed with the left internal tooth; the left seal ring is arranged between the external cylindrical surface of the left side of the left external tooth and the inner hole of the internal tooth; the end tooth of the left internal tooth is matched with that of the right internal tooth, and flanges of the left internal tooth and the right internal tooth are fixed together by virtue of the bolt, the elastic cushion and the nut; the outer cylindrical surface of the right internal tooth is provided with a threaded hole, and the oil cup is arranged in the threaded hole; threaded holes are distributed in the left end face of the right external tooth; the right external tooth is meshed with the right internal tooth; the right seal ring clings to the outer cylindrical surface of the right external tooth and is arranged in an end cover hole; the end cover is connected with the right end face of the right internal tooth by virtue of the screw and the washer; the end face seal ring is additionally arranged between the left end face of the end cover and the right end face of the right internal tooth; the right external tooth can slide freely on the right internal tooth. The nonstandard crowned tooth coupling is simple in structure and changeable in length.

Description

[0001] technical field [0002] The invention relates to the technical field of shaft couplings, in particular to a non-standard drum gear coupling. Background technique [0003] The standard drum gear coupling has the advantages of compact structure, small radius of gyration, large bearing capacity, high transmission efficiency, low noise and long maintenance period. However, there is also a disadvantage that the length of the rotary axis cannot be changed, and it cannot be used in occasions where the length of the rotary axis needs to be changed. Contents of the invention [0004] According to the above deficiencies, the present invention provides a non-standard drum gear coupling with simple structure and variable length. [0005] In order to achieve the above purpose, the non-standard drum-shaped tooth coupling of the present invention mainly includes: including left outer teeth, left sealing rings, left inner teeth, right inner teeth, oil cups, end face sealing rings...
