Abstract

The invention discloses a lever gear drive device, which comprises two sets of levers, a gear set, a second support shaft, and a first support shaft; the lever comprises a power arm, a resistance arm, an inner gear arc and an outer gear arc; The gear set includes a first gear, a second gear and a third gear; the third gear meshes with the inner tooth arc, the first gear meshes with the outer tooth arc, and the second gear and the third gear are fixedly connected and connected with the The second support shaft is rotatably connected; the first gear meshes with the second gear and is rotatably connected with the first support shaft; when one side of the lever is driven, its internal tooth arc and external tooth arc provide driving force at the same time, each tooth arc, Under a reasonable ratio of gear radii, it is ensured that the rotation angles of the second gear and the third gear are the same, so that the second gear and the third gear rotate synchronously and in the same direction. The invention utilizes levers for driving and gear transmission, has a long power arm, less power loss, high power efficiency, high precision, and can ensure a reasonable rotational speed.

Description

technical field [0001] The invention relates to the field of mechanical driving, in particular to a lever gear driving device. Background technique [0002] At present, the commonly used transmission methods mainly include belt drive, chain drive, gear drive and worm drive. Among them, the center distance of the belt drive has a wide range of changes, stable transmission, low noise, simple structure, and low cost. However, the transmission accuracy is low, the efficiency is low, and the service life is short. The center distance of the chain drive has a wide range of changes, and it can work reliably under harsh conditions such as high temperature, oil, and acid, but it has shock, vibration, and noise, and its service life is low. The gear transmission has small outline size, high efficiency, constant transmission ratio, wide range of peripheral speed and power, the most widely used, high manufacturing and installation precision requirements, no buffering, and noise. The w...
