Hangzhou Ka-Machinery Co., Ltd. is a professional production of worm reducer, gear reducer of large-scale industrial and trade enterprises, is committed to providing the industry with professional, efficient and humane overall transmission program.
Schematic diagram of the gear The noise of the reducer is mainly caused by the friction, vibration and collision of the transmission gear. How to effectively reduce and reduce Noise, making it more in line with environmental requirements is also a key research topic at home and abroad. Reducing gear transmission noise has become an important research topic in the industry, many scholars at home and abroad have gear wheel The change of tooth engagement stiffness is regarded as the main factor of gear dynamic load, vibration and noise. With the modification method, so that its dynamic load and speed fluctuations reduced to Minimum, in order to achieve the purpose of reducing noise. This method proved to be a more effective method in practice. However, in this way, the process needs Have modified equipment, the majority of small factories are often unable to implement.
The role of reducer are: worm reducer 1, while reducing the output torque, torque output ratio by the motor output multiplication and reduction ratio, but pay attention not to exceed the reducer rated torque. 2, slow down while reducing the inertia of the load, inertia reduction for the reduction ratio of the square. We can look at the general motor has a value of inertia.
Worm gear reducer used in the process, often encountered when the reducer heating operation. Resulting in rapid wear of the internal worm gear. Once a serious fever, please stop working immediately to find out the reasons for the worm gear reheat and remove. Because once the worm gear reducer serious heat will make the worm and worm wear coefficient decreased, resulting in reducer quickly wear parts. The following is a common cause of the worm gear reducer fever and the general solution: 1, the transmission device is not fixed, worm wear or damage, bearing wear or damage, bolt loosening, foreign body invasion Elimination method: fixed transmission, replace the worm, replace the bearing, tighten the bolt, remove the foreign body and replace the oil leakage 2, the oil seal damage, gasket damage, oil too much, the oil plug loose, oil mark damage Elimination method: replace the oil seal, replace the gasket, add the appropriate amount of oil, tighten the oil plug, replace the oil mark forc...
Leakage is a common thing, which not only a waste of resources, but also on the life of reducer impact. So it is necessary to reducer oil leakage analysis. In a closed reducer, each pair of gear meshing heat, with the long running time, so that the temperature inside the gear box gradually increased, while the deceleration of the chassis volume unchanged, the pressure inside the box also increases, the box Lubricant oil by flying oil, sprinkle the slowdown in the box wall. As the oil permeability is relatively strong, the pressure in the box, which is not strict sealing, oil will penetrate out from there. Reducer design caused by unreasonable oil leakage, such as the design of the reducer no ventilation hood, reducer can not achieve pressure, resulting in higher and higher pressure inside the box, then there will be oil spills. Therefore, the reducer maintenance is critical

Engine fault identification When the engine control system is abnormal, the alarm lamp will light (flashing). When the key switch is set to the "ON" position, it lights up (about 6 seconds) and goes off when the engine is started. (1) Do not operate while the alarm lamp is on (flashing). In this state, the driver will become the cause of fuel consumption deterioration and power reduction. Therefore, please check and repair the nearest service station. (2) In order to indicate that the vehicle is a vehicle with a speed control device, the vehicle with the speed control device (SLD) keeps the key switch in the "ON" position for 15 seconds or more while the engine is stopped, the engine control The alarm lamp flashes three times (approximately 1 second for a 1-second interval). (3) If the engine control system is abnormal when the engine is in the stop state when the key switch is in the "ON" position, the warning lamp will continue to blink, so the speed control can not be confirmed Dev...
