Abstract
The utility model discloses a bearing box. The bearing box comprises a box body; a plurality of screwed holes are formed and uniformly distributed on the circumference of the box body; a lug boss is arranged on the inner side of the box body; a plurality of screwed holes used for jacking are formed and uniformly distributed on the lug boss so as to take out a bearing from the bearing box; and a maze sealing ring-shaped groove is formed on the lug boss in a position matched with a wheel axle or an axle sleeve so as to ensure that the bearing is lubricated when in use. As the lug boss in the bearing box is in tight contact with the outer ring of the bearing, when a wheel set is needed to be dismounted, the bearing box as well as the bearing can be taken out at the same time by using a jacking bolt to jack a moving trolley web through the jacking screwed holes, and another bearing can be taken out from the bearing box by using bolts with specifications corresponding three jacking screwed holes at the other end of the bearing box to jack through the three jacking screwed holes.
Description
Technical field
The utility model relates to a kind of bear box, the bear box device on specifically a kind of crane rail line operating unit.
Background technology
At present, more the supporting form of crane rail line operating unit adopts and hangs the angle bearing box structure, the bore hole formula is installed by set of wheels and 45 ° of dissection types are installed set of wheels.It is complicated to hang the angle bearing box structure, and weight is big, and part is many, and setting accuracy is low.It is difficult to bearing is taken off from axletree when the dismounting bearing though the bear box of bore hole formula structure has improved precision.45 ° of shortcomings that dissection type also exists bearing to be difficult to dismantle.Existing these three kinds of forms are only considered the easy installation and removal of set of wheels single-piece, but as but related components interference fit and be difficult to dismounting and replace on Chang Yinwei and the set of wheels of the bearing of consumable accessory, have to use special speciality tool dismounting for this reason, sometimes even have to take means of destruction, do not scrap and under the situation that bearing has damaged, whole unloading process is extremely wasted time and energy especially at wheel.
Summary of the invention
At above-mentioned the deficiencies in the prior art, the utility model provides a kind of bear box, and this bear box is the advantage of existing structure comprehensively, and can easily bearing be separated set of wheels.
The utility model is achieved through the following technical solutions:
A kind of bear box comprises casing, is evenly distributed with some tapped bore on the casing periphery, and it is characterized in that: described box inside is provided with boss, is evenly distributed with some jack-up on the boss and uses tapped bore, is used for bearing is taken out in bear box.
Described boss and axletree or axle sleeve cooperation place are provided with labyrinth packing annular groove, guarantee that bearing is lubricated in use.
Be evenly distributed with four jack-up on the described boss and use tapped bore.
During use, bear box of the present utility model is the same with bear box of the prior art to be installed and used.When needing the removing vehicle tyres group, because of bear box inner convex platform and outside race closed contact, use jack bolt to withstand the walking carriage web by the jack-up tapped bore, bear box is together taken out together with bearing, can use the bolt of corresponding specification that bearing is taken out in bear box at three jack-up tapped bore of the bear box other end.
The beneficial effects of the utility model are, can be when not using exclusive instrument or other complicated means, and the convenient dismounting that finish main parts size in the set of wheels fast, simple in structure, result of use is good.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the schematic rear view of Fig. 1;
Fig. 3 is a running condition reference diagram of the present utility model.
Wherein, 1, wheel; 2, bear box; 3, bearing; 4, axletree; 5, end cap; 6, vehicle frame; 7, casing; 8, boss; 9, tapped bore; 10, jack-up tapped bore; 11, labyrinth packing annular groove.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described:
A kind of bear box comprises casing 7, is evenly distributed with some tapped bore 8 on casing 7 peripheries, and as shown in Figure 1 and Figure 2, described casing 7 inboards are provided with boss 8, are evenly distributed with four jack-up tapped bore 10 on the boss 8, is used for bearing 3 is taken out from casing 7.Described boss 8 is provided with labyrinth packing annular groove 11 with axletree 4 cooperation places, guarantees that bearing 3 is lubricated in use.
During use, bear box of the present utility model is the same with bear box of the prior art to be installed and used, as shown in Figure 3.When needing the removing vehicle tyres group, earlier end cap 5 is removed from bear box 2, remove the nut of fixed type bearing 3 again, remove the bolt of fixed type bearing case 2 then, and by tapped bore 9 bear box 2 is pushed up from vehicle frame 6 with this bolt, because of bearing 3 outer rings contact with boss 8, so in bear box 2 dismountings, bearing 3 is separated axletree 4 in the lump, take out bearing 3 by nail nipping tapped bore 10 this moment again in casing 7, after bearing 3 was changed and installed, corresponding opposite side also adopted same steps as to replace.
When wheel need be changed, after a side bearing case 2 dismountings finish, between opposite side wheel 1 and vehicle frame 6, fill in weighting material and opposite side bear box 2 can be removed, take out wheel 1 and axletree 4 from frame 6, separate axletree 4 and wheel 1 at last again.
Claims (3)
