Description
Technical Field
The utility model belongs to the technical field of the stirring speed reducer, concretely relates to parallel axis helical gear speed reducer of no oil leakage.
Background
In the prior art, the rotating speed of a stirring tank used in the chemical industry is reduced through a speed reducer, a driving wheel with a small diameter on a motor transmission shaft is used for driving a driven wheel with a large diameter to rotate so as to reduce the rotating speed, and the speed reduction mode is widely applied.
The traditional speed reducer has the technical problems of large abrasion and short service life; in order to prolong the service life of the gearbox, oil is required to be coated on the contact part where the transmission shaft is meshed with the gear frequently for lubrication, although the service life of the gearbox can be prolonged, the transmission shaft rotating at a high speed can splash lubricating oil from an output shaft, so that the technical problems of oil waste and environmental pollution exist, oil flows incompletely in the box body, and part of the meshing parts of the gear cannot be fully coated with the oil, so that the gearbox is unsmooth in lubrication and unstable in operation.
Secondly, in the field of food, the phenomenon of food pollution caused by oil leakage at the output shaft is very common, and the food cannot be used after being polluted, so that the production cost is high; and the traditional large-torque speed reducer is difficult to apply due to the influences of poor lubrication and oil leakage along with the higher viscosity of the stirred materials in the field of food.
The utility model discloses a patent number is 201820575181.4's utility model patent discloses a novel parallel shaft speed reducer can spray lubricating oil at the reducing gear box internally through the oil pump that sets up, and the principle is taken inside lubricating oil of inside out for utilizing the external oil pump of reducing gear box and spouts to the reducing gear box inside through the copper pipe again, provides the guarantee for smooth operation. However, the drawback begins to appear after using for a period of time, because the oil pump is the accessory of adopting outward, the quality of oil pump is great to the influence of speed reducer, and the life and the quality of oil pump can not match with the speed reducer promptly, just so cause the phenomenon that the speed reducer can't normally work because of the damage of oil pump, and the phenomenon that later stage equipment repair returns the factory is very common for the normal development of enterprise is controlled by the accessory of adopting outward, and the condition is more unfavorable. In addition, the structure with the oil pump also needs to be provided with a copper pipe, and the assembly process of the equipment is complicated and inconvenient.
Therefore, it is necessary to design a parallel shaft reducer that can achieve a good lubrication effect without an oil pump.
Disclosure of Invention

In order to achieve the purpose, the utility model relates to a parallel shaft helical gear reducer without oil leakage, which comprises a reduction box body; the top end of the reduction box body is provided with a motor, and a transmission shaft of the motor is in transmission connection with an input shaft in the reduction box body;
the input shaft is in meshed transmission connection with a first reduction gear on the rotating shaft through a gear I; the rotating shaft is in meshed transmission connection with a second reduction gear on the output shaft through a gear II;
an oil blocking boss is arranged at the rotary connection position of the output shaft and the reduction box body; the top end of the oil blocking boss is mutually attached to the bottom surface of the second reduction gear in a sliding manner;
and an oil throwing toothed sheet is arranged at the bottom of the input shaft.
Furthermore, the oil slinger tooth plates are arranged in a petal type by taking the input shaft as the center of a circle.
Furthermore, the oil slinger tooth sheet is inclined leftwards or/and rightwards.
The utility model discloses rational in infrastructure, the preparation of being convenient for, overall structure obtains abundant subtracting, has saved oil pump and copper pipe, and the installation is more swift. The lubricating oil is thrown out at a high speed by arranging the oil throwing toothed sheet at the bottom of the input shaft, a good lubricating effect can be achieved, an oil pump is omitted, the cost is saved, and the use stability and the service life of equipment are also improved.
