An extrusion equipment speed reducer output connection structure, as shown in fig. 1-3, includes: the extrusion device comprises a speed reducer body 1, an extrusion device body 2, a spline housing 3 and a positioning sleeve 4; the reducer body 1 has an output shaft 11; the end face of the spline housing 3 is fixedly connected with the end face of the output shaft 11; an axially through-hole structure is arranged in the spline housing 3, and a plurality of internal spline teeth are arranged on the inner wall of the through-hole structure; the extrusion apparatus body 2 has an input shaft 21; a plurality of external spline teeth are arranged on the circumferential outer side of one end of the input shaft 21; the external spline teeth extend into the internal spline teeth of the spline sleeve 3 to form spline connection; one end face of the positioning sleeve 4 is fixedly connected with the end face of the input shaft 21, and the other end face is tightly attached to the end face of the output shaft 11 and used for axially positioning the input shaft 21.
The utility model comprises a plurality of spline housings 3 and positioning sleeves 4 with different lengths, when the length of an input shaft needs to be changed or the input shaft 21 needs to be moved when the processing materials, technical requirements and the like of an extrusion equipment body 2 change, the input shaft 21 is only needed to be drawn out from the spline housing 3, then the spline housing 3 and the positioning sleeve 4 are taken down, the spline housings 3 and the positioning sleeves 4 with other lengths are replaced, and then the input shaft 21 is inserted into the spline housing 3, so that the adjustment of the input shaft 21 can be completed, the speed reducer body 1 can adapt to the input shafts 21 with different lengths and different positions without being disassembled and adjusted, the assembly efficiency of the speed reducer body 1 and the extrusion equipment body 2 can be greatly improved, simultaneously, a plurality of output shafts 11 are avoided to be processed, and the use cost of the speed reducer body 1 is saved.
In consideration of improving the assembly efficiency of the output shaft 11 and the spline housing 3, as shown in fig. 2 to 4, a positioning groove 111 is formed in the end surface of the output shaft 11 connected with the spline housing 3, and a positioning boss 311 is formed in the end surface of the output shaft 11 connected with the spline housing 3; when the output shaft 11 is fixedly connected with the spline housing 3, the outer side surface of the positioning boss 311 is tightly attached to the inner side wall of the positioning groove 111. When the output shaft 11 is equipped with the spline housing 3, the positioning boss 311 can limit the radial movement of the spline housing 3 after being placed in the positioning groove 111, thereby facilitating the fixed mounting of the output shaft 11 and the spline housing 3.
In consideration of ensuring that the output shaft 11 and the end surface of the spline housing 3 can be tightly attached, as shown in fig. 2, the height of the positioning boss 311 is smaller than the depth of the positioning groove 111, so as to prevent the end surface of the positioning boss 311 from abutting against the bottom surface of the positioning groove 111, which results in that the end surfaces of the output shaft 11 and the spline housing 3 cannot be tightly attached, and finally the coaxiality of the output shaft 11 and the spline housing 3 after installation is affected.
Since the input shaft 21 inevitably generates axis wobbling in the transmission, collision occurs between the input shaft 21, the position sleeve 4 and the output shaft 11. In consideration of avoiding the deformation of the part caused by the acting force generated by the collision, as shown in fig. 2, the two side end faces of the positioning sleeve 4 are both plane structures perpendicular to the axial direction, and the plane structures can ensure that the acting force generated by the collision faces the axial direction of the input shaft 21, the positioning sleeve 4 and the output shaft 11, so as to avoid generating component forces in other directions, thereby better preventing the deformation of the part.
