1. Spline connection is used to connect the driving part with the bevel gear
2. Customers can process the reserved whole position according to their own actual working conditions
3. If you have any other requirements, please consult with the sales department of Stard-Gear
1) When the gearbox leaves the factory, the protection grade is IP65 and IP67.But only refers to the inside of the gearbox. IP protection level according to EN60529/IEC529 according to GB/T4208.IP65/IP67 applies to standard environment; IP68 is suitable for the water depth is not more than 1 meter, duration is not more than 72 hours of work environment. The working environment requirements need to be clarified in the previous contract.
2) gear box standard working environment temperature -20℃ ~ 120℃ seals are made of butadiene rubber (NBR) or liquid sealant gear box. When working in high temperature and low temperature environment, the seals are made of high and low temperature resistant seals according to the requirements of working conditions.(Special environment, need to be clear in the earlier contract)
3) The cover and other parts of the gearbox shall not be removed after delivery to the end customer, as doing so will damage the sealing of the gearbox and lead to leakage.
