Abstract

The invention discloses an oil leak-proof parallel shaft helical gear reducer which comprises a reduction gearbox body, wherein a motor is arranged at the top end of the reduction gearbox body, and atransmission shaft of the motor is in transmission connection to an input shaft in the reduction gearbox body; the input shaft is in engaged transmission connection to a first reducing gear on a rotating shaft through a gear I; the rotating shaft is in engaged transmission connection to a second reducing gear on the output shaft through a gear II; an oil baffle bump table is arranged at the rotatable connection of the output shaft and the reduction gearbox body; the top end of the oil baffle bump table is in attached sliding connection to the bottom surface of the second reducing gear; and anoil slinging gear sheet is arranged at the bottom of the input shaft. The whole structure is simplified fully and an oil pump and a copper tube are cancelled, so that the mounting process is more convenient and rapid. By arranging the oil slinging gear sheet at the bottom of the input shaft to sling lubricating oil at a high speed, a good lubricating effect can be achieved. The oil pump is cancelled, so that the cost is lowered and the using stability of the oil leak-proof parallel shaft helical gear reducer is further improved and the service life of the oil leak-proof parallel shaft helicalgear reducer is further prolonged.

Description

technical field [0001] The invention belongs to the technical field of agitating reducers, and in particular relates to a parallel shaft helical gear reducer without oil leakage. Background technique [0002] In the prior art, the mixing tank used in the chemical industry uses a reducer to reduce the speed of stirring, and mostly the driving wheel with a small diameter on the drive shaft of the motor drives the driven wheel with a large diameter to rotate to reduce the speed. The deceleration method is widely used. [0003] The traditional reducer has the technical problems of heavy wear and short service life; in order to improve its service life, it is necessary to frequently apply oil to the contact parts of the drive shaft and gear mesh for lubrication, although it can improve its service life, but the high-speed rotating transmission The shaft will cause the lubricating oil to splash and leak from the output shaft, which has technical problems of both oil consumption a...
