6. The helical gear reducer with noise reduction effect according to claim 5, characterized in that: The processing table (22) is integrally arranged at the center of the upper end of the functional cover (2); the circulating oil groove (4) is arranged through the processing table (22); the circulating oil groove (4) in the processing table (22) is arranged in a "J"-shaped structure; the upper end of the circulating oil groove (4) in the processing table (22) horizontally penetrates the processing table (22) and a replacement groove is opened on one side; the processing table (22) is integrally provided with a threaded joint (28) located on one side of the replacement groove; the threaded joint (28) is provided with an internal thread; one side of the processing tube (29) is horizontally inserted and arranged in the circulating oil groove (4); one side of the processing tube (29) placed in the circulating oil groove (4) is provided with a plurality of filter holes and flow-through grooves; the processing tube (29) is placed in the threaded joint (28) and connected by threads; and one side of the processing tube (29) placed in the threaded joint (28) is sleeved with a sealing gasket.

7. A method for reducing noise of a helical gear reducer, characterized in that: The helical gear reducer noise reduction method is applied to the helical gear reducer according to any one of claims 1 to 6, comprising the following steps: Step 1: Connect the two functional covers (2) from both sides of the helical gear reducer (1) so that the functional covers (2) and the helical gear reducer (1) are fitted together; Step 2: Rotate the worm screw (9) to control the two telescopic connection boxes (6) to move relative to each other, and insert the two sealing plug connectors (7) into the circulating oil groove (4) of the functional cover (2) respectively, and under the action of the sealing ring, the sealing is reliable; Step 3: Then the soundproof cover (30) is plugged into the hanging strips (31) of the two functional covers (2) through the docking plate to keep the helical gear reducer (1) and the functional cover (2) in stable contact, and under the action of the limit plate (32) set by the spring, the position of the soundproof cover (30) is stably limited to increase the range of noise reduction; Step 4: When the reducer is in use, the reduction shaft (12) is driven to rotate, thereby driving the gear (14) to control the driven gear (15) to rotate rapidly, thereby achieving rapid up and down reciprocating motion of the piston rod (19); Step 5: Under the pushing action of the pressure delivery piston (20), the lubricating oil in the helical gear reducer (1) enters the pressure delivery groove (18) from the oil inlet groove (35), and is pushed into the telescopic connection box (6) and the circulating oil groove (4) on one side; Step 6: Under the action of continuous pressure, the lubricating oil flows through the groove into the processing cylinder (29), is filtered and discharged from the processing cylinder (29), and then flows back into the helical gear reducer (1) through the telescopic connection box (6) on the other side, thereby completing the heat dissipation and treatment of the lubricating oil in the helical gear reducer (1) and improving its service life; Step 7: When replacing the treatment cylinder (29), the adjusting disk (26) is rotated to control the two stop balls (23) to rotate 90 degrees, thereby sealing the circulating oil tank (4) in the treatment table (22). The treatment cylinder (29) is then rotated, removed and replaced. In addition, filter cotton can be added to the treatment cylinder (29) to improve the filtering effect.
