Description

Sealed installation frock of magnetic suspension switch lockpin gearbox Technical Field The utility model relates to rail transit, in particular to a sealing installation tool for a magnetic suspension turnout lock pin gearbox. Background The magnetic suspension turnout lock pin gearbox is provided with two identical seals which are respectively positioned at two sides of the gearbox. One for the gearbox input shaft coupled to the motor drive shaft and the other for the output shaft coupled to the encoder. In the normal application process of the gearbox, the lubricating oil in the lock pin gearbox is leaked due to abrasion of the sealing lip, and the damage of the gears of the lock pin gearbox is caused by excessive oil leakage. When the seal is replaced and installed, the seal is difficult, and time and labor are wasted. Because the seal is plastic, the outer edge has a certain hardness. The installation is difficult to rely on the direct pressure equipment of manpower to put in place, does not have suitable assembly tool moreover, can only adopt dummy to beat, how to keep sealed week circle can balanced the packing into, and the degree of difficulty is great. When the sealing lip is assembled, the sealing lip is damaged or the outer edge is deformed, so that the sealing is scrapped and the previous work is abandoned. In addition, when the seal is replaced, the motor or encoder connected to the gearbox must first be removed, and after the seal is installed, the motor or encoder must be reassembled into place, often requiring advance preparation. And in addition, the seal replacement is only carried out in a window period of about 6 hours from the end of the current day to the beginning of the next day of the operation of the maglev train, so that the time is short and the maintenance pressure is high. Disclosure of utility model The utility model aims to overcome the defects existing in the prior art, and provides a sealing installation tool for a magnetic suspension turnout lock pin gearbox.
