A torque transmission mechanism, electric starter, engine and garden tool

Abstract

The invention relates to the technical field of garden tools, in particular to a torque transmission mechanism, an electric starting device, an engine and a garden tool. The torque transmission mechanism includes a first transmission member, a second transmission member, and an elastic buffer located between the first transmission member and the second transmission member, the elastic buffer configured to buffer and transfer the first transmission member The torque of the second transmission member. By using the elastic buffer to transmit the torque, the torque of the first transmission member is temporarily buffered by the elastic buffer during the torque transmission process, and then the torque is transmitted to the second transmission by the elastic buffer, which solves the problem of gears and scrolls in the prior art. The hook claws connected between the springs and between the scroll spring and the ratchet are easy to break, and the elastic buffer has a simple manufacturing process, low cost, low transmission noise, and is easy to disassemble and operate, without the need for additional safety protection components.

Description

technical field [0001] The invention relates to the technical field of garden tools, in particular to a torque transmission mechanism, an electric starting device, an engine and a garden tool. Background technique [0002] In the prior art, a small gasoline engine is usually equipped with an electric starting device. The electric starting device usually includes a starter motor, a power transmission mechanism and a clutch mechanism. The power transmission mechanism includes a reduction box and an energy storage assembly. The output torque is transmitted to the energy storage component through the reduction box, and the energy storage component converts mechanical energy into potential energy. When the stored potential energy reaches the threshold value, it is released to the clutch mechanism instantly and makes it rotate. The clutch mechanism meshes with the crankshaft and drives the crankshaft to rotate to start. gasoline engine. After the gasoline engine starts, the trans...
