Also it is machined with shoulder block on the inside hole wall of wherein one end of bearing mounting hole, erects at the other end and be machined with on seat along the circumferentially distributed some baffle plate installing holes of bearing mounting hole；Or it is machined with on the perpendicular seat outside bearing mounting hole two ends respectively along the circumferentially distributed some baffle plate installing holes of bearing mounting hole.
Preferably, it is connected between base with perpendicular seat and has smooth transition surface.
Preferably, base is also machined with round key installing hole.
Preferably, perpendicular seat being also machined with lubricating cup installing hole, the inner of lubricating cup installing hole connects with bearing mounting hole.
The invention also discloses a kind of quarry tipper tripod bearing fixation assembly, including above-mentioned bear-sleeve casting, the oscillating bearing being assemblied in bearing mounting hole, the bearing pin being assemblied in oscillating bearing, it is assemblied in the bearing baffle on baffle plate installing hole by securing member, and is sleeved on the spacer ring on the bearing pin of oscillating bearing both sides.
This utility model has the advantages that
1, by certain moulding, it is to avoid stress is concentrated so that it is have enough intensity and good fatigue life, it is possible to effectively vehicle frame and rear axle housing are coupled together, this simple in construction easily realizes, is easy for installation and removal and the maintenance in later stage.
2, fix not only by bolt between base and rear axle housing, coordinate also by round key, make bolt all to shearing force under any operating mode.
3, shoulder block and bearing baffle are used for stopping oscillating bearing axial float, and the spacer ring of oscillating bearing both sides reduces the gap between oscillating bearing and vehicle frame thus prevents bear-sleeve casting from swinging.
4, lubricating cup installing hole is used for installing lubricating cup, and timing to oscillating bearing charging-up lubricant oil, extends active time by lubricating cup.

Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is further described.Following example are only used for clearly illustrating the technical solution of the utility model, and can not limit protection domain of the present utility model with this.
Embodiment one
As shown in Figures 2 to 4, a kind of quarry tipper tripod bearing fixation assembly, including bear-sleeve casting 3, oscillating bearing 8, bearing pin 5, bearing baffle 7, and spacer ring 6.
Bear-sleeve casting 3 includes fixing base 3-2, and is connected between the perpendicular seat 3-1, base 3-2 being vertically fixed on base 3-2 and perpendicular seat 3-1 and has smooth transition surface 3-4.Base 3-2 is also machined with some counter sink 3-3 near marginal position, and base 3-2 middle position is machined with round key installing hole 3-8.The bearing mounting hole 3-5 of fixing joint bearing 8 it is machined with on perpendicular seat 3-1, lubricating cup installing hole 3-9 also it is machined with on perpendicular seat 3-1, the inner of lubricating cup installing hole 3-9 connects with bearing mounting hole 3-5, and lubricating cup installing hole 3-9 is used for installing lubricating cup, and timing passes through lubricating cup to oscillating bearing 8 charging-up lubricant oil.Also it is machined with shoulder block 3-6 on the inside hole wall of wherein one end of bearing mounting hole 3-5, the perpendicular seat 3-1 outside its other end is machined with along some baffle plate installing hole 3-7 circumferentially distributed for bearing mounting hole 3-5.
Oscillating bearing 8 is assemblied in bearing mounting hole 3-5, and bearing pin 5 is assemblied in oscillating bearing 8, and bearing baffle 7 is fixed on the baffle plate installing hole 3-7 of perpendicular seat 3-1 by securing member 9, and bearing pin 5 exposes to be set with a spacer ring 6 in the part of oscillating bearing 8 both sides.In the present embodiment, shoulder block 3-6 and bearing baffle 7, in the both sides of oscillating bearing 8, are used for stopping the axial float of oscillating bearing 8.Spacer ring 6 is also fitted with the both sides at oscillating bearing 8, is used for preventing tripod bear-sleeve casting 3 from swinging.
During installation, as it is shown in figure 1, be first assembled in the bearing mounting hole 3-5 of tripod bear-sleeve casting 3 by oscillating bearing 8, and use securing member 9 that bearing baffle 7 is installed to the position of correspondence.Bolt 4 is used to be installed on rear axle housing 2 the tripod bear-sleeve casting 3 with above part afterwards, and avoid bolt 4 by shearing force by round key auxiliary assembling, again the rear axle housing 2 with above part is installed on the correspondence position (thrust frame bearing) of vehicle frame 1, and prevent tripod bear-sleeve casting 3 from swinging at the left and right sides of oscillating bearing 8 suit spacer ring 6, finally bearing pin 5 is sequentially passed through the side of the thrust frame bearing of vehicle frame 1, spacer ring 6, oscillating bearing 8, the opposite side of the thrust frame bearing of spacer ring 6 and vehicle frame 1, and prevent it from rotating by fixing with vehicle frame 1 for one end of bearing pin 5, thus complete assembling.
