Single-row denominator subtraction reducer

Abstract

The invention relates to a planet row gear structure reducer which comprises a mechanical system, a lubricating system and the like. The reducer includes a single-row bevel gear planet row or a single-row variable-line-speed planet row with the characteristic parameter close to 1.0, wherein the motion characteristic equation of the single-row bevel gear planet row or the single-row variable-line-speed planet row is that Nt-axNq-(1-a)xNj=0. The reducer has a specific transmission path, the transmission path or a heterogeneous type of the transmission path with the corresponding transmission ratio formula having the denominator subtraction property is selected, the value of the planet row characteristic parameter is adjusted by selecting the planet row kind structure type and adjusting the number of teeth of three parts of the planet row, the denominator subtraction property can be utilized so that the transmission ratio formula denominator absolute value can be minimized, the member absolute value is not minimized, the transmission ratio absolute value is maximized, and therefore the reducer with the large transmission ratio is achieved. The reducer can serve as an independent reducer and accelerator or serve as a part in a transmission machine.

Description

technical field [0001] The invention relates to a planetary-row mechanical reducer, specifically a single-row planetary-row reducer with a characteristic parameter close to 1.0, which utilizes the denominator subtraction property of its transmission ratio formula. Background technique [0002] In order to flexibly change the torque and speed of the power system in a wide range, many power machines are equipped with mechanical reducers. The existing mechanical reducers mainly include cylindrical gear reducers, worm gear reducers, planetary gear mechanical reducers, cycloidal pin wheel reducers, harmonic drive reducers, etc. Among the existing reducers, the cylindrical gear reducer and the worm gear reducer have a large volume and a small transmission ratio; the cycloidal pin wheel reducer and the harmonic drive reducer have complex structures, high manufacturing costs, and low transmission torque; The gear reducer with a row gear structure has a simple structure, but general...
