A lawn mower is also called a lawn trimmer, etc. The lawn mower is a mechanical tool used for mowing lawns, vegetation, etc. It is composed of a cutter head, an engine, a walking wheel, a walking mechanism, a blade, a handrail, and a control part. The cutter head, equipped with an engine is installed on the traveling wheel, and the output shaft of the engine is equipped with a blade. The blade uses the high-speed rotation of the engine to increase the speed a lot, saving the weeding worker's working time and reducing a lot of human resources.
The lawn mower uses lawn mower belts to transmit power and realize the connection between the components. The lawn mower belt has a certain degree of flexibility and large bearing capacity, so the lawn mower belt is a common realization form of power transmission. In actual practice, the tightness of the belt has an important influence on the transmission efficiency, and the lawn mower belt in the existing belt transmission device is generally of a fixed design, which is fixed after the initial installation. However, in actual situations, due to the presence of temperature, humidity, and other factors, the yard machine riding lawn mower belt tension is inconsistent, which easily leads to a drop in transmission efficiency, especially the larger the belt, the more obvious the impact.
Unifying the tightness of the belt can solve the problem of reduced transmission efficiency to a certain extent. The specific operation is that the tension of the belt can be adjusted by setting up a tension pulley, a tension sleeve adjusting plate, and a tension sleeve fixing plate. In this way, it can prevent the belt tension from being inconsistent, improve the transmission efficiency, and avoid affecting the working efficiency of the lawn mower. At the same time, this approach can change the adjustment method, making the adjustment of the belt tension more simple and convenient, and easy to operate.
