Abstract

The invention relates to the technical field of aerator speed reduction. A large torque cone-hypocycloid speed reducer of a rotary-brush aerator is disclosed, and is characterized by being composed of a bevel gear pair and a hypocycloid transmission. The bevel gear pair comprises a drive bevel gear and a driven bevel gear; the hypocycloid transmission comprises a hypocycloid gear ring, a cycloid gear and a W output mechanism; a screw hole installed with a vent cap is disposed on a stand; an oil return hole is disposed in a stand bearing hole; the oil return hole is located below a space between an oil seal and a bearing; the hypocycloid gear ring is connected to a stand inner hole; an oil filling hole is disposed in a circular end cover on a small stand end surface; an oil level gauge is installed in the hole; and the oil level gauge can be pulled out to check an oil quantity and rapidly fill oil. The large torque cone-hypocycloid speed reducer of a rotary-brush aerator has the following advantages that: (a) the hypocycloid gear teeth cannot be broken, so that the overload capacity is greater than the external meshing transmission of a parallel shaft; (b) the price of a cycloid speed reducer is lower than a half of a planet speed reducer, so that the cost is 30-35% lower than the latter; and (c) an oil quantity in the speed reducer can be rapidly checked, and oil can be rapidly filled in a dirt and outdoor environment.

Description

【Technical field】

[0001] The invention relates to the technical field of deceleration of aerators, and relates to a high-torque cone-inner pendulum reducer for a rotary brush aerator. 【Background technique】

[0002] The rotary brush aerator is widely used in the treatment of urban domestic sewage and industrial wastewater in petroleum, chemical, leather, printing and dyeing, papermaking, food, gas and other industries. The environment in which the aerators are used is quite harsh. There are many aerators in operation in a large open-air sewage treatment plant. It is cold in winter and hot and smelly in summer. No one of the workers wants to stay for a few minutes longer. The rotary brush aerator is mainly composed of two parts: the rotary brush and the reducer. Among them, the SEW-like K series bevel gear + helical hard tooth surface reducer has the highest failure rate.

[0003] This is because the background technology K series hard tooth surface reducer has the following...
