1、 The core role of overload protection mechanism During the operation of the rice mill, the load may suddenly increase sharply due to excessive feeding, mixing of hard impurities (such as stones, metals) in the material, or internal jamming of the equipment. If there are no effective protective measures, the huge torque generated by this overload will be directly transmitted to the reducer, wh
1. Compact structure, highly adaptable to rice milling equipment space The cycloidal gear reducer adopts the planetary transmission principle and the cycloidal gear meshing structure, with the input shaft and output shaft aligned on the same straight line. This design significantly reduces its size and weight compared to conventional reducers of the same power. In rice milling machines, this co
1、 Core benchmark judgment rules Rotation matching principle: The backstop can be divided into two types: clockwise (S) and counterclockwise (N), which should fully correspond to the actual normal working rotation direction of the high-speed shaft of the reducer. For example, when driving an upward belt conveyor, the counterclockwise (N) model should be selected. Incorrect installation of the c
1、 Core function failure The backstop is a one-way locking device, and its internal structure (such as wedges and rollers) has clear directionality. Once installed in reverse, in working conditions where the equipment needs to prevent reversal (such as shutdown or power outage), the backstop not only fails to lock, but also remains in a "free" state, causing the equipment to reverse under the a
1. Immediate shutdown and thorough discharge Once serious contamination of gear oil is found, the equipment should be stopped immediately to prevent the deteriorated oil from exacerbating the wear of key components such as gears and bearings during operation. After marking the shutdown, open the drain valve at the bottom of the fuel tank and drain all the deteriorated oil inside. If there is a
1、 Observe the appearance and equipment operation status This is the most basic preliminary judgment method, which detects signs of pollution through abnormal sensory and equipment performance: Appearance: Normal gear oil is usually clear or slightly yellowish, with no impurities or emulsification. If the oil becomes turbid, it indicates the presence of solid particles mixed in; If the oil e
1、 Material selection: laying the foundation for performance The material of the internal gear ring is the cornerstone of its performance, and different steels can achieve a performance leap from soft tooth surface to hard tooth surface through heat treatment, to adapt to the harsh working conditions of the cutting machine. 1. Alloy impregnated carbon steel (preferred for hard tooth surfaces
1、 The influence mechanism of tooth profile on transmission smoothness and noise 1. Tooth profile accuracy is the foundation High precision tooth profile ensures smooth transition of gears during meshing, reducing impact and vibration. On the contrary, tooth profile errors (such as tooth profile deviation and tooth pitch error) can cause gears to collide at the moment of meshing and disengag
