Abstract

The invention discloses a lever gear driving device. The device comprises two levers, a gear set, a second supporting shaft and a first supporting shaft, wherein each lever comprises a power arm, a resisting arm, an inner toothed arc and an outer toothed arc; the gear set comprises a first gear, a second gear and a third gear, the third gear is meshed with the inner toothed arc, the first gear ismeshed with the outer toothed arc, and the second gear is fixedly connected to the third gear and is rotationally connected to the second supporting shaft; the first gear is meshed with the second gear and is rotationally connected to the first supporting shaft; and when the lever on one side performs driving, the inner toothed arc and the outer toothed arc provide driving force at the same time,under the reasonable radius matching of the toothed arcs and the gears, it is guaranteed that the second gear and the third gear rotate by the same angle, and the second gear and the third gear synchronously rotate in the same direction. According to the device, the levers are used for driving and gear transmission, the power arm is long, the power loss is small, the force effect is high, the precision is high, and a reasonable rotating speed can be guaranteed.

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...
