Abstract
The invention relates to the technical field of speed reduction of aeration machines, in particular to a large-torque cone-hypocycloid speed reducer of a rotary brush aeration machine. The large-torque cone-hypocycloid speed reducer is characterized by comprising a bevel gear pair and a hypocycloid drive, wherein the bevel gear pair comprises a drive bevel gear and a driven bevel gear; the hypocycloid drive comprises a pin wheel housing, a needle pin, three cycloidal wheels and a W output mechanism, wherein a screw hole with a ventilation cap is formed on an engine base, an oil return hole is arranged in a bearing hole of the engine base, the oil return hole is located below a space between an oil seal and a bearing, the pin wheel housing is connected to an inner hole of the engine base, an oil feeding hole is arranged in a round end cover on the small end face of the engine base, an oil scale is arranged in the hole, and the oil scale is drawn to check the oil quantity and refuel rapidly. The large-torque cone-hypocycloid speed reducer of the rotary brush aeration machine has the advantages that: (a) hypocycloid wheel teeth are continuous, so that the overload capacity is larger than external gearing transmission of a parallel shaft, and bearing capacities of three bearings can be increased by 50 percent; (b) the price of the hypocycloid speed reducer is less than one third of a hard tooth surface, so that the cost is 50-55% lower than that of the hard tooth surface; and (c) the oil quantity in the speed reducer can be rapidly checked and the oil can be rapidly refueled to the speed reducer in both dirty and exposed environments.
Description
[technical field]
The present invention relates to aerator braking technique field, retarder is bored-put to a kind of rotary-brush type aerator high pulling torque.
[background technique]
The rotary-brush type aerator is widely used in the Industrial Wastewater Treatment of the industries such as city domestic sewage and oil, chemical industry, process hides, printing and dyeing, papermaking, food, coal gas.The Environmental Conditions of aerator is quite abominable, and there are a lot of platform aerators in a very large open-air sewage-farm in running, and winter is cold, summer is not only hot but also smelly, and the workman whoever do not think many slow-witted upper a few minutes.The rotary-brush type aerator mainly forms by turning brush and speed reducer two major parts, wherein bores the rate of fault of tooth+helical teeth reducer with hardened tooth surface with the K series of imitative SEW the highest.
This is because there is following problems in background technique K series reducer with hardened tooth surface:
(1) working life is short: only a some months high speed level conical tooth shaft holds fracture, cone tooth broken teeth in actual use, its reason is that level cone tooth is positioned at highest point at a high speed, the lubricant oil that the slow speed turbine stage gear splashes is not enough to lubricating bearings, the bad lubricated bearing that makes is just thirsty oily early, cause the retainer fracture, the roller that is scattered (steel ball) makes again the bevel gear snaggletooth;
(2) the oil mass site inspection is difficult in the K series reducer with hardened tooth surface cabinet, oiling is very inconvenient;
(3) " cone tooth+parallel axes " reducer with hardened tooth surface is domestic imitative SEW company product, thereby selling at exorbitant prices.
[summary of the invention]
That the object of the invention provides is a kind of " cone tooth+cycloid " double reduction, long service life, lubricated reliable, Fuel Check is convenient and retarder is bored-put to the low rotary-brush type aerator high pulling torque of price.
Because the Environmental Conditions of aerator is very poor, not only dirty but also be open-air, thereby require that retarder is light, long service life, that overload capacity reaches greatly price is low, the cycloid transmission possesses above-mentioned requirements fully: can use the more than ten years, price only is 1/3rd of the hard flank of tooth; Require the oil reserve inspection in not easy oil leakage, the case convenient, easy to lubricate.
The advantage of cycloid transmission is: (a) single-stage speed reducing is than large; (b) cycloidal gear teeth broken teeth never; (c) manufacture cost is less than 1/3rd of the hard flank of tooth.Technological scheme of the present invention is as follows:
(A) adopt the three-disk cycloid wheel to improve the technological scheme of cycloid carrying and impact resistance:
SUMITOMO CHEMICAL FA three-disk cycloid wheel decelerator is the cycloid transmission of current new development, and three cycloid wheel phase angles are staggered 120 °.Its advantage is: (1) volume is little, lightweight; (2) because there not being pin gear sleeve, the maximum deceleration ratio can reach 119 (" calculating of three-cycloid gear driver cycloid wheel intensity " Machine Designs 2007.10); (3) the rotary arm bearing weak link is improved; (4) pin tooth and pin stress equalization, stable drive; (5) bearing capacity increases by 50% in theory.
(a) gerotor structure is simple, part is few in addition, single-stage speed reducing is larger than very; In addition, cycloidal gear teeth has very high counter-bending ability;
(b) adopt cage type W output mechanism, make the cantilever pin become freely supported structure, improved the crooking ability of pin, the short two block bearings distance of axial dimension is large, makes transmission more steady;
(B) screw of a dress abat-vent is arranged on the support, oilhole once in the support bearing hole, spill port are below between oil sealing and the bearing, and little support end face upper joint one nose circle lid has a tank filler sleeve in the described nose circle lid, device one oil scale in the tank filler sleeve.
[beneficial effect]
The present invention contrasts the existing hard flank of tooth parallel shaft (speed) reducer of aerator, and its novelty, creativeness and practicability are embodied in:
(a) cycloidal gear teeth broken teeth not, thereby overload capacity is larger than parallel axes outer gearing transmission, three wheel bearing capacities increase by 50%;
(b) the cycloidal reducer price is less than 1/3rd of the hard flank of tooth, thereby the low 50-55% of cost;
(c) not only dirty but also be in the open-air atmosphere, can check fast oil mass and rapid refueling in the retarder.
