The improved combination device for the joint bearing and the universal pin roll comprises a pin roll baffle plate, a dish-shaped gasket, a large flat dish, a bolt, a fixing block, a supporting base, a spacer ring B, a sealing cushion, a joint bearing, a fixing object and a retainer ring, wherein the pin roll is a hollow pin roll; the pin roll and the baffle plate are welded together and capable of penetrating through the supporting base, the sealing cushion, the spacer ring B, the retainer ring, the joint bearing and the fixing object in sequence; an opening is formed on the baffle plate; the baffle plate is blocked on the fixing block; the fixing block is welded on the supporting base; a threaded hole is formed in the fixing block; and the bolt penetrates through the dish-shaped gasket, the large flat dish and the fixing block in sequence for fixedly connecting the baffle plate with the fixing block. Compared with the existing joint bearing-pin roll combination device, the improved combination device for the joint bearing and the universal pin roll is lighter in weight, convenient to mount and dismount and capable of realizing full-penetration welding, so that the welding strength of the baffle plate and the pin roll is higher, and therefore, the condition that the gasket is sunken to the U-shaped opening of the baffle plate after being damaged is avoided, and the connecting reliability of the bolt is increased.
Description
Technical field
The utility model relates to the general bearing pin composite set of a kind of improved joint shaft bearing, belongs to joint shaft bearing and bearing pin composite set technical field.
Background technique
Mine truck is the key equipment during surface mine exploitation and the extensive earthwork are built, and is for the professional equipment of ore or cubic metre of earth transportation, has characteristics such as load-carrying is big, working efficiency height.At present mine truck have towards maximize, the trend of hugeization development, also more and more harsher to the requirement of the bearing structure intensity of mine truck, and the Placement of joint shaft bearing is to the structural strength decisive role.
At present, both at home and abroad on the electronic quarry tipper of large-tonnage, the fixed pin shaft of joint shaft bearing mainly contains following two kinds of means of fixation: a kind of is to adopt to get through the hole at flange circumference and bearing pin circumference, fix with bolt again or install baffle plate additional at the bearing pin head, fix in the mode of bearing pin afterbody machining screw; This means of fixation has several shortcomings: the first, and circumference perforation processing difficulty; The second, bolt bears the shearing force of circumferential and axial in the course of the work simultaneously, and is all influential to the reliability of working life of bolt and system; The 3rd, the pin shaft structure complexity.Another kind of means of fixation as shown in Figure 1, it mainly is made up of bearing pin 1, baffle plate 2, dish-shaped pad 3, bolt 4, fixed block 5, side plate 6, flange 7, spacer ring A8 and joint shaft bearing 9, after bearing pin 1 welds with baffle plate 2, bearing pin 1 passes side plate 6, flange 7, spacer ring A8 and joint shaft bearing 9 successively, have gap on the baffle plate 2, be stuck on the fixed block 5, fixed block 5 is welded on the frame, and be provided with tapped hole, utilize dish-shaped pad 3 and bolt 4 that baffle plate 2 is compressed, can overcome preceding a kind of means of fixation shortcoming, limit rotation and the axial float of bearing pin simultaneously.But also there are the following problems: the first, and solid pin only can be used for little tonnage quarry tipper, if when being used for the large-tonnage dumping car, is not easy to installation owing to bearing pin is overweight; The second, bearing pin baffle plate welding cut is too small, can not realize the full-penetration welding, influences the intensity of bearing pin; The 3rd, only use the butterfly pad under the bolt, because butterfly pad external diameter is less relatively, easily take place to be absorbed in the U-shaped opening of baffle plate after pad damages, thereby the inefficacy that causes bolt connects.
Summary of the invention
Problem at above-mentioned prior art existence, the utility model provides a kind of improved joint shaft bearing general bearing pin composite set, it is in light weight, be convenient to install, dismantle, can realize the full-penetration welding, make baffle plate and bearing pin weld strength higher, the situation of avoiding being absorbed in the U-shaped opening of baffle plate after the pad damage takes place, and increases the connection reliability of bolt.
To achieve these goals, the technical solution adopted in the utility model is: the general bearing pin composite set of a kind of improved joint shaft bearing, comprise the bearing pin baffle plate, the dish pad, big plate, bolt, fixed block, bearing, spacer ring B, sealing gasket, joint shaft bearing, fixture, back-up ring, bearing pin is hollow bearing pin, bearing pin and baffle plate weld together, and pass bearing successively, sealing gasket, spacer ring B, back-up ring, joint shaft bearing and fixture, have gap on the baffle plate, be stuck on the fixed block, fixed block is welded on the bearing, and be provided with tapped hole, screw bolt passes dish pad, big plate and fixed block are fixedlyed connected baffle plate with fixed block.
Gap on the baffle plate is U-shaped opening.
The beneficial effects of the utility model are: compare existing joint shaft bearing bearing pin combination, this combination possesses following advantage: the first, use hollow bearing pin at the large-tonnage quarry tipper, and satisfying under the bearing pin strength condition, reduced the weight of Assembly of pin, be convenient to install, dismantle; The second, bigger welding cut is arranged on the bearing pin baffle plate, can realize the full-penetration welding, make baffle plate and bearing pin weld strength higher; The 3rd, the big plate of use and butterfly pad combination under the bolt can prevent from being absorbed in the gap of baffle plate after pad from damaging, thereby has increased the connection reliability of bolt.
Description of drawings
Fig. 1 is the structural representation of existing joint shaft bearing bearing pin means of fixation;
Fig. 2 is structural representation of the present utility model.
Among the figure: 1, bearing pin, 2, baffle plate, 3, dish-shaped pad, 4, bolt, 5, fixed block, 6, side plate, 7, flange, 8, spacer ring A, 9, joint shaft bearing, 10, big plate, 11, bearing, 12, spacer ring B, 13, sealing gasket, 14, fixture, 15, back-up ring.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 2, the general bearing pin composite set of a kind of improved joint shaft bearing, comprise bearing pin 1, baffle plate 2, dish pad 3, big plate 10, bolt 4, fixed block 5, bearing 11, spacer ring B12, sealing gasket 13, joint shaft bearing 9, fixture 14, back-up ring 15, bearing pin 1 is hollow bearing pin, bearing pin 1 welds together with baffle plate 2, and pass bearing 11 successively, sealing gasket 13, spacer ring B12, back-up ring 15, joint shaft bearing 9 and fixture 14, have gap on the baffle plate 2, be stuck on the fixed block 5, fixed block 5 is welded on the bearing 7, and being provided with tapped hole, bolt 4 passes dish-shaped pad 3 successively, big plate 10 and fixed block 5 are fixedlyed connected baffle plate 2 with fixed block 5.
During use, what adopt because of bearing pin 1 is hollow bearing pin, is satisfying under the bearing pin strength condition, has reduced the weight of Assembly of pin, is convenient to installation and removal; Bigger welding cut is arranged between bearing pin 1 and the baffle plate 2, can realize the full-penetration welding, make baffle plate 2 and bearing pin 1 weld strength higher; Bolt uses big plate 10 and 3 combinations of butterfly pad for 4 times, and the situation that can prevent from being absorbed in after butterfly pad 3 from damaging in the gap of baffle plate 2 takes place, thereby has increased the connection reliability of bolt.
Preferably, the gap on the baffle plate 2 is U-shaped opening, cooperates with the peripheral shape of fixed block 5, further reduces to be absorbed in the gap of baffle plate after pad damages, and increases the connection reliability of bolt.
