Plastic speed reducer, preparation method and mold for molding plastic speed reducer box body

Abstract

The invention discloses a plastic speed reducer, a preparation method and a mold for forming a plastic speed reducer box body, and relates to the field of aquaculture. According to the technical scheme main point, inserts in a bearing chamber can support an input shaft and an output shaft, supporting blocks on one side of the input shaft extend upwards, a bearing seat for connecting the supportingblocks is arranged at the upper part of the supporting blocks. The plastic speed reducer, the preparation method and the mold for forming the plastic speed reducer box body have the technical effectsthat the bearing seat, the two inserts and the input shaft form a frame structure in a relative state, a main shaft of a motor acts on a driving spiral bevel gear, the driving spiral bevel gear transmits centrifugal force generated by rotation of the motor to the bearing seat, and acting force is borne by the frame structure which is formed by the bearing seat, the two inserts and the input shaftin a relative state; and an original plastic box body does not bear the acting force of the part any more, so that the torsion at a flange position of the box body is removed, the deformation problemof the box body is fundamentally solved, and in addition, the noise problem generated by long-time use is further solved in a non-deformation state.

Description

technical field [0001] The invention relates to the field of aquaculture equipment, in particular to a plastic reducer, a preparation method and a mold for forming a casing of the plastic reducer. Background technique [0002] The aerator is a machine that is often used in fish farming. Its main function is to increase the oxygen content in the water to ensure that the fish in the water will not be hypoxic. At the same time, it can also inhibit the growth of anaerobic bacteria in the water and prevent the deterioration of the pool water from threatening the living environment of the fish. [0003] The power part of the aerator will use the reduction box. Since the box body of the reduction box is made of aluminum or casting, on the one hand, it is heavy and needs to provide a large buoyancy in the water; on the other hand, it is easy to rust, so it is not suitable for aquaculture. Industry. [0004] At present, the Chinese patent whose publication number is CN107685424B di...

Problems solved by technology

Due to the deformation of the box, the plane where the flange is located is inclined, resulting in the inclination of the motor shaft connected to it, and the change of the meshing angle of the internal gears, which increases the wear of the gears, affects the life of the gears, and generates a lot of noise
