Multi-stage submerged reducer

Abstract

The invention discloses a high-performance multilevel under-liquid speed reducer comprising a box seat and a box cover covering the box seat. A first-level rotary shaft, a second-level rotary shaft and a third-level rotary shaft are rotationally arranged between the box cover and the box seat. The first-level rotary shaft is provided with a first-level gear. The second-level rotary shaft is provided with a third-level gear and a second-level gear meshing with the first-level gear. The third-level rotary shaft is provided with a fourth-level gear meshing with the third-level gear. An oil storage groove is formed in the bottom of the interior of the box seat. The fourth-level gear extends into the oil storage groove. An oil passing channel located above the oil storage groove is formed in the position, corresponding to the peripheral wall of the fourth-level gear, of the inner wall of the box seat. A strainer is arranged on the oil passing channel. A fixing hook part for fixing the strainer is arranged between the strainer and the oil passing channel. The high-performance multilevel under-liquid speed reducer has the following advantages and effects that higher transmission performance is achieved, and service life is longer.

Description

technical field [0001] The invention relates to the technical field of a transmission device, in particular to a multistage submerged reducer. Background technique [0002] The reducer is generally used for low-speed and high-torque transmission equipment. The motor, internal combustion engine or other high-speed running power is used to achieve the purpose of deceleration through the gear with a small number of teeth on the input shaft of the reducer and the large gear on the output shaft. Ordinary The reducer will also have several pairs of gears with the same principle to achieve the ideal deceleration effect. The ratio of the number of teeth of the large and small gears is the transmission ratio. [0003] Since the parts of the reducer will have certain processing errors and assembly errors during the processing and assembly process, the occurrence of this error will cause the gears to wear during the transmission process, which is the so-called running-in period. The w...

Problems solved by technology

The wear of the gears will produce a certain amount of iron filings, which will fall into the oil in the tank under the action of gravity, and the iron filings in the oil can easily re-enter between the gears under the agitation of the gears , thus causing secondary wear to the gear, affecting the service life and transmission performance of the reducer
