But it also has some problems. According to relevant information: when the transmission ratio of the harmonic transmission reducer is tens of revolutions per revolution, its transmission efficiency is 90%. When it is three hundred and forty revolutions per revolution, It has a transmission efficiency of 70%

Embodiment Construction

[0014] The present invention mainly includes housing 9, input shaft 7, output shaft 8 and related gears contained in housing 9, it is different from the prior art in that: input shaft 7 is fixedly connected with planetary gear shaft 1; 2 is fixedly connected with gear 3; gear 4 is fixedly connected with housing 9; output shaft 8 is fixedly connected with gear 5.

[0015] Gear 6 is installed on the extended part of the output shaft shaft center by bearing, and the place that output shaft and input shaft are connected with housing is all equipped with bearing, and planetary gear is fixed on the planetary gear shaft 1 by bearing.

[0016] Gear 2 meshes with internal gear 4; gear 3 meshes with internal gear 5, and gear 3 meshes with gear 6 at the same time.

[0017] ( Figure 5-1 ) The length from the center point of gear 2 to the meshing point with gear 4 is "active arm a", the meshing point of gear 2 and gear 4 is the "support point c" that bears gravity, and the part of gear 3...

Abstract

The invention relates to direct-acting gear speed increaser (decelerator), which is driven by the lever balancing the gravity, and since only one point of engagement of two gear teeth bear sliding friction coefficient produced by certain gravity at any ratio of transmission, the problem that higher ratio of transmission will result lower efficiency of transmission in the field of speed increaser (decelerator). Said invention has simple structure, easy production, and high efficiency of transmission. Since it can set any ratio of transmission just by adjusting the relative parameter of the diameter ratio of gear without increasing the collocated amounted of gear, it has small volume and lower weight. And three collocated amounted of symmetrical planetary gear improve the meshing ratio of gear teeth, and increase the supporting efficiency of speed increaser (decelerator) significantly while steady operation. Said speed increaser (decelerator) can suit the speed increaser in wind generator, as well as the field which need high ratio and super high ratio of transmission with certain supporting ability.

Description

Technical field: [0001] The present invention relates to the technical field of the speed increaser (decelerator), because it is directly driven by balancing the weight of a lever arm, so it is specifically a "direct-acting gear speed increaser (decelerator)". Background technique: [0002] In the existing technical field, the harmonic drive reducer is a high-ratio reducer, and its first-stage retrieval transmission ratio can reach 500 revolutions per revolution, so it has a wide application prospect in high-ratio reduction equipment . But it also has some problems. According to relevant information: when the transmission ratio of the harmonic transmission reducer is tens of revolutions per revolution, its transmission efficiency is 90%. When it is three hundred and forty revolutions per revolution, It has a transmission efficiency of 70%. Invention content: [0003] The object of the present invention is to provide a direct-acting gear speed increaser (reducer), which c...
