Therefore, for addressing the above problem, need to be improved existing planet carrier structure, avoid planet carrier to produce the defects such as tissue looseness, pore, sand holes in the process of casting, guarantee the sealability of planet carrier respective side panels simultaneously, can adopt lubricant oil to be lubricated planetary gear train, improve the usability of planetary gear train, increase the service life.
Model utility content
In view of this, the purpose of this utility model is to provide a kind of planet carrier of being convenient to casting processing, can avoid planet carrier to produce the defects such as tissue looseness, pore, sand holes in the process of casting, can guarantee the sealability of planet carrier respective side panels simultaneously, can adopt lubricant oil to be lubricated planetary gear train, the usability that improves planetary gear train, increases the service life.
The planet carrier of being convenient to casting processing of the present utility model, the pto＝power take-off that comprises the first side plate, the second side plate, is fixedly connected on the disc between described the first side plate and the second side plate and is fixed on the first side plate; Described pto＝power take-off is hollow shaft; Described the first side plate is provided with and connects with pto＝power take-off endoporus and aperture is not less than the hole of dodging of pto＝power take-off endoporus;
Further, also comprise the capping of dodging hole described in being sealingly fastened in;
Further, described pto＝power take-off and the first side plate are one-body molded;
Further, described capping connects and fixes in dodging hole by jump ring;
Further, described capping and dodging between the inwall of hole seals by seal ring;
Further, described in, dodging hole is step hole; Described capping periphery is the step surface with dodging hole and matching;
Further, described the second side plate and disc and the first side plate are one-body molded.
The beneficial effects of the utility model are: the planet carrier of being convenient to casting processing of the present utility model, can avoid planet carrier to produce the defects such as tissue looseness, pore, sand holes in the process of casting, can guarantee the sealability of planet carrier respective side panels simultaneously, can adopt lubricant oil to be lubricated planetary gear train, the usability that improves planetary gear train, increases the service life.
