The width of bearing box is 14cm～16cm; Be provided with the locking nut hole that to insert locking nut at the top of bearing box; Be provided with the connection screw hole that can insert the connection screw at the two ends of bearing box; Oil inlet pipe is installed on filler opening, and oil inlet pipe is provided with the dust cover that can prevent that dust from getting into.

The chamfering that on end cap, is provided with is 8 * 45 °, and the quantity of crossing oil groove is 4～8, and the degree of depth and the width of crossing oil groove are 6～8mm.

End cap is provided with the pasta staff gauge pipe that can observe gear oil fuel head and the groove of draining the oil that inserts oil-draining locknut.

Between bearing box and end cap, be provided with sealing gasket.

Filler opening be arranged on that bearing and end cap front-end face fit directly over.

Be provided with the bearing box base in the bottom of bearing box.

The bearing box base is provided with the screw attachment hole.

Owing to adopted technique scheme; During the utility model work; Along with the rotation of the rotating band dynamic bearing of working shaft in bearing box,, strengthened the circulation of gear oil owing to chamfering that is provided with at the end cap front-end face and mistake oil groove; The centrifugal force driven gear oil that produces when bearing operation protects on the ball of bearing, has protected bearing; Owing to adopted technique scheme; The utility model compared with prior art; That the utility model not only has is simple in structure, make the advantage novel, that fabricating cost is low; But also have safe and reliablely, save the energy, prolonged bearing working life, reduced user cost, can be fully immersed in bearing in the gear oil, reached advantages such as better cooling and lubrication effect.

Embodiment

The embodiment of the utility model: the box bearing box of a kind of novel tooth comprises bearing 2, shown in Fig. 1～6; Bearing 2 is installed in the bearing box 1, is provided with filler opening 3 at the top of bearing box 1 and can the locking of bearing 2 shells be prevented the locking nut 4 that shell rotates, and is installed with end cap 6 through connecting screw 5 respectively in the right ends of bearing box 1; The outer ring of the front end of left and right sides end cap 6 and bearing 2 fits; End cap 6 end faces that fit with bearing 2 are provided with chamfering 7 and cross oil groove 8, in the axis hole of left and right sides end cap 6, are provided with oil sealing 9, and oil sealing 9 is a prior art products; Can prevent that the gear oil in the bearing box is left to outside the device; Oil sealing 9 must be placed in end cap 6 the insides, and whether during assembling, it is concentric with working shaft to observe bearing box 1.

The width L of bearing box 1 is 14cm～16cm, and the length of the employed bearing box 1 of the utility model is 1.3 times of existing employed bearing box length, the more gear oil of in bearing box 1, can packing into like this, the number of times of minimizing charge of oil; Be provided with the locking nut hole 10 that to insert locking nut 4 at the top of bearing box 1, be provided with at the two ends of bearing box 1 and can insert the connection screw hole 11 that connects screw 5, oil inlet pipe 12 is installed on filler opening 3; Oil inlet pipe 12 is provided with the dust cover 13 that can prevent that dust from getting into; Oil inlet pipe 3 is not only the import of adding gear oil, but also produces the relief opening of waste gas when being work, filler opening 3 be arranged on that bearing 2 and end cap 6 front-end faces fit directly over; Like this when refueling; Fluid can flow in the bearing box faster, and during exhaust, waste gas is also discharged in bearing box more easily.
