Problems solved by technology
[0003] At present, the screw shaft used by the screw conveyor is very long as a whole, and it needs to adopt segmented production connection. The current connection is mainly a rigid connection. The rigid flange is rigidly connected with the upper and lower (or front and rear) screw shafts. The structure is simple and easy. However, there are the following limitations: the rigid connection is a statically indeterminate structure, and the structural deformation and installation error of the screw shaft will cause an abnormal increase in the support reaction force at the support part, which will cause excessive energy consumption of the screw conveyor; processing errors and installation errors will cause screw conveyors Shaft vibration shock

The invention provides a spherical gear coupling for screw shafts, and relates to the technical field of couplings. The coupling is characterized in that a mounting ball is arranged at one end of an outer spherical gear shaft, a positioning plane is arranged at the end, away from the outer spherical gear shaft, of the mounting ball, and a first flange is arranged at the other end of the outer spherical gear shaft; a second flange is arranged at one end of an inner spherical gear shaft, an inner spherical gear seat is arranged at the other end of the inner spherical gear shaft, a mounting groove is formed in the inner spherical gear seat, the inner wall of the mounting groove comprises a first spherical peripheral surface and an inner end surface, the first spherical peripheral surface is suitable for being connected with a spherical spline of the mounting ball, and a positioning ball is arranged at the center of the inner end surface; and a spherical gear cap is suitable for sleeving the mounting ball, the inner wall of the spherical gear cap comprises a second spherical peripheral surface and a straight peripheral surface, the second spherical peripheral surface matches the spherical surface of the mounting ball, the inner diameter of the straight peripheral surface is larger than the diameter of the outer spherical gear shaft, and the spherical gear cap is suitable for being connected with the inner spherical gear seat so that the mounting ball can be fixed in the mounting groove. According to the coupling, the performance of the connected spiral shafts is improved.
Description
technical field [0001] The invention relates to the technical field of shaft couplings, in particular to a ball tooth coupling for a helical shaft. Background technique [0002] In the field of bulk cargo transportation, screw conveying equipment is popular among users for its excellent environmental protection performance. The intermediate support and connection mode of the screw shaft is one of the key technologies of the screw conveyor equipment, and its performance has a decisive impact on the energy consumption, operation stability, and precision requirements of manufacturing and installation of the screw conveyor. [0003] At present, the screw shaft used by the screw conveyor is very long as a whole, and it needs to adopt segmented production connection. The current connection is mainly a rigid connection. The rigid flange is rigidly connected with the upper and lower (or front and rear) screw shafts. The structure is simple and easy. However, there are the following...
