[0015] As Figs. 1 to 5 The utility model discloses a combined press transmission gear, including replacement and general part, and the replacement and general part coaxial arrangement and spline connection, and the replacement is composed of two half gears 1, and the general part includes two half ring plates 2, and two half ring plates 2 are detachably spliced into cylindrical structure, to prevent the radial gap of spline connection, and the replacement is screw-threaded connected with the annular end face of one side of the general part through a plurality of circumferentially uniformly distributed bolts 3, and the shaft hole 4 is set up in the center of the replacement.

[0016] The half ring plate 2 one end along the axial line direction is set up with the through slot and is formed with the connecting plate, and the connecting plate is set up with the through hole 6 at intervals, and the half ring plate 2 other end is set up with the threaded hole 5 corresponding with the through hole 6, and two half ring plates 2 are spliced into a whole through bolt connection.

[0017] The end face of half ring plate 2 and half gear 1 is uniformly set with a plurality of bosses 7 along the circumference, and the shaft hole 4 hole wall of half gear 1 is set up with a plurality of recesses 8 corresponding with boss 7.

[0018] The specific operation process of the utility model is as follows:

[0019] Two half ring plates 2 are spliced into cylindrical structure and the boss 7 is towards the same side, and the bolt passes through the through hole 6 on the first half ring plate and is fastened in the threaded hole 5 on the second half ring plate through rotation, and similarly, the bolt passes through the through hole 6 on the second half ring plate and is fastened in the threaded hole 5 on the first half ring plate through rotation, and then the recess 8 on two half gears 1 and boss 7 are spline connected, and the bolt 3 is used to fasten half gear 1 and half ring plate 2 together to combine into complete press transmission gear.
