Installation requirements and precautions of transmission sprocket

Installation requirements ① Select the drive sprocket model correctly according to the model specifications. ②Check whether the position where the drive sprocket is installed (transmission output countershaft, hub, etc.) is in good condition, otherwise the relevant parts must be overhauled or replaced. ③Install the main and driven sprockets in place according to the correct method, and tighten the fasteners to meet the specified torque requirements. ④After installing the drive chain and adjusting the tightness, check whether the chain and the sprocket are smoothly matched, coplanar, and there is no interference with the chain cover. Precautions: ①The driven sprocket should have anti-loosening measures. ②After the driven sprocket is loaded into the vehicle, the rear wheel axle should be adjusted with the adjuster and the rear cradle (also called the rear wheel fork) markings. This can prevent the rear wheel from deviating, and also avoid the early stages of the sprocket and chain. Wear. ③It is best to replace the sprocket and chain at the same time. If only one of them is replaced, the wear of both will be aggravated. ④Due to the high speed of the driving sprocket and the small number of teeth, it wears faster than the driven sprocket under the same conditions, which is normal. ⑤ Clean and lubricate the drive chain and drive sprocket regularly to improve their service life.
