Does the imported transmission need maintenance?
Thread Content
Distinguished colleagues: Our department has imported Laverken and Flander transmissions, which have been in operation for three years; the requirement for the next cycle is for them to operate for four years. Take a look and see if maintenance is needed; there is a shortage of maintenance capabilities in the country, so what should be done? Attention, please, thank you!
It needs to be checked, but very carefully – every detail from the gaps to the seals must be precise. Saying that there is a shortage of maintenance capacity in the country is somewhat unfair.
Thank you for the expert advice. Please have the teacher explain in detail the maintenance plan and the required standards. Thank you!
You can refer to the factory settings for inspection; the inspection of the transmission mainly focuses on issues related to the mating surfaces.
Hehe, based on practical experience, there’s no need for maintenance or disassembly; just change the oil properly. As long as it has been disassembled, any sealing O-rings will cause problems, and oil leakage will occur once it’s reassembled
It’s not really any complex technology; please contact me if maintenance is needed.
Regular maintenance must be carried out, actually it should be called regular inspection. There are many components in the reducer that need to be replaced after it is opened; prepare these spare parts in advance. If you’re really worried, contact the supplier; it’s also a good idea to have the manufacturer’s after-sales support come and provide guidance, as this will allow you to learn a lot. Ask the technician to prepare a report afterwards.
Many devices these days undergo preventive maintenance, and inspections are also carried out to prevent accidents caused by potential problems. But if there is no data indicating the need for maintenance, why waste so much effort? Especially given the current poor economic conditions in the chemical industry, many companies only carry out maintenance work after identifying problems; if there are no relevant data indicating the need for maintenance, I personally recommend leaving the system as it is
Conduct vibration monitoring on the gearbox, perform lubricant analysis, and check the oil seals on site to assess the operating condition of the gearbox. In a well-functioning gearbox, rolling bearings theoretically have a limited service life, but there should be no major issues with long-term operation of a reducer or one with a lower speed. Sliding bearings or reducers in large-scale units, based on their vibration levels, operate stably; especially in imported equipment, there are no vulnerable components, and in my opinion no maintenance is needed either. Regarding the methods for maintenance, considering stability, it is best to have the work done by the manufacturer; this involves adjustments such as those to the gear surface, gear contact, side clearance, and bearing play. Moreover, many manufacturers do not provide this type of data, so decisions have to be made based on experience
Please provide the contact information of the expert, thank you!
According to the description, your company is responsible for the long-term operation of the equipment; with a long maintenance cycle, and since the gearbox has been in use for three years, it should need maintenance now； It’s not necessary to repair it, but it definitely needs to be checked to determine if there is any problem. If there are problems once it’s put into operation, it will be troublesome to deal with them later. You can contact professional gearbox manufacturers.
