The above technical purpose of the present invention can be achieved by the following technical solutions: the utility model provides a coaxial bevel gear speed reducer, includes the box and rotates and set up in the output shaft and the input shaft of box, coaxial setting between output shaft and the input shaft, the box internal rotation is provided with the pivot, be equipped with along with pivot pivoted second grade bevel gear and tertiary bevel gear in the pivot, be equipped with on the input shaft along with the input shaft rotate and with the one-level bevel gear of second grade bevel gear meshing, be equipped with on the output shaft along with the output shaft rotate and with tertiary bevel gear meshing's level four bevel gear.

By adopting the technical scheme, the bevel gears are matched to change the transmission ratio, so that the effects of reducing the rotating speed and increasing the torque are realized; and the change and the compensation of the bevel gear transmission direction are matched, so that the output shaft and the input shaft can be in a coaxial state through the structure, the use of some special working conditions is adapted, and the practicability of the bevel gear is improved.

Further setting the following steps: the box includes main part, first connecting pipe and second connecting pipe, the input shaft rotates to set up in first connecting pipe, output shaft and rotates to set up in second connecting pipe, pivot and rotate and set up in the main part, all through bolted connection between first connecting pipe and the main part, between second connecting pipe and the main part.

Through adopting above-mentioned technical scheme, install the pivot in the main part earlier respectively, the input shaft is installed in first connecting pipe, output shaft and is installed in the second connecting pipe, installs main part, first connecting pipe and second connecting pipe three again for the equipment operation of this speed reducer is more convenient.

Further setting the following steps: tapered roller bearings are arranged between the input shaft and the first connecting pipe, between the main body and the rotating shaft and between the output shaft and the second connecting pipe.

By adopting the technical scheme, the tapered roller bearing can play a more stable limiting role on the shaft along the axial direction of the shaft and reduce the friction resistance in rotation.

Further setting the following steps: the free end of the first connecting pipe and the free end of the second connecting pipe are both provided with bearing glands, sealing rings are arranged between one of the bearing glands and the output shaft and between the other bearing gland and the input shaft, and a plurality of sealing bulges are arranged on the inner peripheral wall of each sealing ring.

Through adopting above-mentioned technical scheme, a plurality of bellied settings of sealing form the multiple seal, promote the leakproofness of the inside cavity of speed reducer to the life of extension speed reducer.

Further setting the following steps: one of them terminal surface of sealing washer is equipped with first deformation groove, be equipped with the spring ring in the first deformation groove.

Through adopting above-mentioned technical scheme, the deformability that has the promotion sealing washer in first deformation groove realizes with the better laminating that needs sealed position, and the setting up of spring coil promotes the power of holding tightly between sealing washer and the axle, further promotes the leakproofness.

To sum up, the utility model discloses following beneficial effect has: the utility model discloses enable output shaft and input shaft and be in coaxial state to adapt to the use of some special operating modes, promote its practicality.
