Abstract

The invention relates to the technical field of speed reduction of an aerator. A cone-cycloid speed reducer for a rotary brush type aerator is characterized by being composed of a bevel gear pair and a cycloid transmission, wherein the bevel gear pair comprises a driving bevel gear and a driven bevel gear; the cycloid transmission comprises a needle toothed shell, a needle pin, a cycloid gear and a W output mechanism; a screw hole for mounting a vent cap is formed on a base; an oil return hole is formed in a base bearing hole; the oil return hole is located under a place between an oil seal and a bearing; the needle toothed shell is linked in a base inner hole; an oil filling hole is formed in a circular end cap on a small end face of the base; an oil scale is mounted in the oil filling hole; and the oil scale is pulled out for checking oil volume and quickly filling oil. The cone-cycloid speed reducer has the beneficial effects that: (a) the cycloid gear is free from tooth breaking, so that the overload capacity is higher than engaging transmission outside a parallel shaft; (b) the cost of the cycloid speed reducer is less than a half of the cost of a planet reducer, so that the cost is reduced by about 30-35%; and (c) the oil volume in the reducer can be quickly checked and the oil can be quickly filled under a dirty open-air condition.

Description

【Technical field】 [0001] The invention relates to the technical field of deceleration specially used for aerators, and relates to a rotary brush type aerator cone-pendulum reducer. 【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 pr...
