Worm gear reducer is one of the commonly used reducers. In the process of using worm gear reducer, it is inevitable that you will encounter problems.
XNUMX. Common problems of worm gear reducer and their reasons:
(1) The drive pinion helical gear is worn, (2) the bearing (at the worm) is damaged.
1 The drive pinion helical gear is worn.It usually occurs on the reducer of the vertical device, mainly related to the increase in the amount of lubricating oil and the selection of lubricating oil.In the case of a vertical device, it is very simple to constitute a lack of smooth oil. When the reducer stops working, the transmission gear oil between the motor and the reducer is lost, and the gear does not get the smooth protection due to it, and it is not useful during starting or operation. The smoothness causes mechanical wear and even damage.
2 Worm bearing is damaged.When the reducer breaks down, even if the reduction box seal is excellent, the factory often finds that the gear oil in the reducer has been emulsified, and the bearing has been rusted, corroded, and damaged. This is due to the fact that the gear The oil is composed of the condensation of moisture that occurs after the heat becomes cold; of course, it is also closely related to the quality of the bearing and the technical methods of the device.
XNUMX. The solution of worm gear reducer:
(1) Ensure the quality of the device.In order to ensure the quality of the device, the factory purchases and cheapens some special items. When disassembling and installing reducer worm gears, worms, bearings, gears and other components, try to avoid direct hits with hammers and other things; when replacing gears, worm gears, and worms, Try to choose original parts and replace them in pairs; when installing the output shaft, pay attention to the cooperation of public service, D≤50mm, choose H7/k6, D>50mm, choose H7/m6, and use anti-sticking agent or red lead oil together. Protect the hollow shaft, avoid wear and rust, avoid dirt on the cooperation area, and it is difficult to disassemble during maintenance.
(2) Selection of lubricating oil and additives.Worm gear reducers usually use 220# gear oil. For some reducers with heavier loads, frequent launches, and poor operating environments, the factory also selects some smooth oil additives (such as Anzhi Chemical Co., Ltd.) to reduce speed. When the machine stops working, the gear oil is still attached to the gear surface to form a protective film to avoid heavy load, low speed, high torque, and metal and metal touch when starting.The additive is also rich in seal ring regulators and anti-leakage agents, allowing the seal ring to maintain softness and flexibility, effectively reducing the appearance of smooth oil leakage.
In short, the hollow shaft worm reducer is convenient to install, reasonable in layout, and reliable in use.Of course, we must also pay attention to choosing the trademark of the reducer. A strong company will describe the key points based on the appearance of the reducer, the placement of the heat dissipation ribs, the calculation of the heat balance, the depiction of the oil circuit, etc., and the actual use and operating conditions of the reducer will be selected. Outstanding manufacturing technology produces high-quality, reliable and durable reducers.Users only need to use the protection correctly to be able to get a satisfying effect
