The outer diameter of bushing and the outer diameter for being more than support shaft, the bushing are pressed between annular stop boss and annular gland in annular
An oil sealing around the support shaft is each provided on the outside of lid and annular stop boss, on the medial surface and outside of bushing
It is correspondingly arranged on the external oil groove and inside tank being connected to by radial direction oil hole on bushing, is provided on the swinging mounting and bushing
The oil filler point of upper external oil groove connection.
Further, swing drive axle is connect with swinging mounting in lubrication system, and the swinging mounting endoporus is located at ring
The wall surface in the outside of shape positive stop lug boss is stepped, and the stair-stepping wall surface and the outer circumference surface of the support shaft are constituted around institute
The first oil seal groove of support shaft is stated, the oil sealing on the outside of the positive stop lug boss that commutates is located in first oil seal groove.
Further, swing drive axle is connect with swinging mounting in lubrication system, the outside mask of the annular gland
There are ring-shaped step, the ring-shaped step to surround the second oil seal groove of the support shaft with the outer circumference surface composition of the support shaft,
The oil sealing on the outside of annular gland is located in second oil seal groove.
Further, swing drive axle is connect with swinging mounting in lubrication system, and inside tank is diameter on the bushing
To the not equal deep varying depth oil groove of depth.
Further, swing drive axle is connect with swinging mounting in lubrication system, and the inside tank is along bushing axis
The spiral in the shape of a spiral on direction.
The utility model compared with prior art, has the following advantages that：By the way that inside tank is arranged in the inside and outside of bushing,
And inside tank is the not equal deep oil groove of non-circumferential direction, improves the lubricant effect of the passability of lubricating oil, improvement swinging mounting and axis；It is logical
The limit method for improving bushing is crossed, the limit effect of bushing is improved, reduces failure.
