Description
Technical field
The utility model relates to the reducing motor class, especially a kind of reducing motor with high-efficiency seal structure that is applied in the chemical industry stirring industry sealing be had requirement.
Background technology
Reducing motor is with its compact conformation, volume is little, operate steadily, the advantages such as noise is low, a lot of automation industries have been applied to, and chemical industry stirs industry owing to its industry particularity, and what a lot of reactors stirred is that dangerous substance has not allowed wet goods impurity to enter reactor, so the reducing motor that stirs power is had higher requirement.
What the industry that stirs at present a lot of chemical industry still adopted is old-fashioned cycloidal planetary gear speed reducer, has leakage of oil, and noise is large, safeguards the shortcomings such as frequent.After adopting reducing motor, can well avoid above problem, but the employing of reducing motor output is rotary rubber oil sea sealing, still can be owing to oil sealing is aging in long-term the use, the reasons such as oil sealing shelves wearing and tearing, the reducing motor output has the possibility of a small amount of leakage lubricating oil.The dangerous substance stirring need to improve the reducing motor output end sealing structure the requirements at the higher level of reducing motor sealing reliability in the industry because chemical industry stirs.
Chemical industry stirs in the industry, and reducing motor is vertical installation, and the inner oil-immersed type that adopts of reductor is lubricated, and the internal gear bearing is complete not in lubricating oil.Motor slows down by the driven gear running and increases transmitting torque work during reducing motor work, and gear rotates will stir lubricating oil, oil temperature height, and the power of motor loss, this part power loss is referred to as thermal power.If reductor internal gear rotating speed is higher, the lubricated thermal power that produces of oil-immersed type is larger, and the power output of reducing motor more reduces.
The utility model content
The technical problems to be solved in the utility model is: based on the problems referred to above, provide a kind of possible reducing motor with high-efficiency seal structure of oil leak that at utmost reduces.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of reducing motor with high-efficiency seal structure, comprise reductor and motor, the output shaft of described reductor is downward, described motor has motor shaft, motor shaft is connected to the high speed level driving gear of reductor, the level driving gear is meshed with a high speed level driven gear at a high speed, the level driven gear connects the center tooth axle at a high speed, the spindle nose of center tooth axle is provided with the cam oil pump, the cam oil pump is positioned at the lubricating oil of reductor inside, the cam oil pump connects the copper oil pipe, the exit of copper oil pipe is positioned at senior driving gear top, the lubricating oil of reductor inside has the oil level line, and the reductor outlet internal is provided with the oil removal cover, and the oil level line is below oil removal cover top.
The drive unit of described cam oil pump is the center tooth axle.The driving power of grease pump need not to fill in addition power source.The change of so only carrying out in reductor inside does not all exert an influence to installation dimension and the profile of reductor outside.
Center tooth axle spindle nose in reductor inside is installed the cam oil pump, band moving cam operation of oil pump when the center tooth axle turns round, and the cam oil pump is drawn onto lubricating oil in the copper oil pipe, and lubricating oil will be transported at a high speed level driving gear place of reductor along the copper oil pipe.After lubricating oil was sprayed on the high speed level driving gear, because level driving gear velocity of rotation is fast at a high speed, lubricating oil will be thrown away at a high speed, be splashed to casing top, flow to again inner each bearing of reductor and gear engagement place, be equivalent to fountain lubricated, reached the effect that reductor normally lubricates.Can reduce like this oil level line of reductor internal lubrication oil, so that can not stir lubricating oil during gear operation, thus avoided the thermal power loss of reducing motor excessive.
Because lubricating oil level can reduce, and at the reductor outlet internal oil removal cover is set, the oil level line is avoided lubricating oil to surpass and is entered oil removal cover inside after oil removal is overlapped below oil removal cover top, has been equivalent to form the pattern of dry-well mechanism.Installing additional of oil removal cover guaranteed that lubricating oil can't enter in the output bearing chamber of reductor, avoided lubricating oil directly to contact with oil sealing, thereby also avoided the rear oil seepage phenomena that occurs of the long-term use of reductor output sealing.
The beneficial effects of the utility model are: the change that the utility model only carries out in reductor inside, and the driving power of cam oil pump need not to fill in addition power source, like this installation dimension and the profile of reductor outside are not all exerted an influence, and the lubricated copper oil pipe of fountain is installed in inner internal circulation system, the leakage of oil possibility that has also produced from stopped outer circulation at all of adopting of reductor.Thermal power loss when the change of lubricating system has also largely reduced reducing motor work has reduced lubricants capacity, cooperates the dry well type sealing device, can satisfy chemical industry and stir special industry does not allow leakage of oil to reducing motor requirement.
