The invention relates to a special gearbox for compact modular plastic extruder, which comprises a gearbox shell, a high-speed transmission module, a low-speed transmission module and an output shaft. The high-speed transmission module consists of input gear shafts and pinions with various speed ratios. The low-speed transmission module consists of a fixed-speed ratio intermediate gear shafts and large gears. The parallel arrangement of input teeth is installed in the gearbox shell. Shaft, intermediate gear shaft, output shaft, coaxially mounted pinion of intermediate gear shaft, large gear on output shaft, meshing connection between big gear and intermediate gear shaft, meshing connection between pinion and input gear shaft. The gear transmission of the invention adopts two transmission modules to improve the generalization degree of parts, shorten the manufacturing cycle of products and meet the minimum inventory requirement at the same time; the self-aligning thrust bearing is installed in the gap between the big gear and the shell, which maximizes the space utilization ratio and reduces the overall manufacturing cost of the product; and the pre-tightening amount of the output shaft can be accurately adjusted and lifted by adopting the lock nut and thrust ball bearing structure. High product reliability.
