In the drawings: the device comprises an input spiral bevel gear 1, an output spiral bevel gear 2, an input shaft 3, an output shaft 4, a shell 5, a double-row angular contact bearing 6, a tapered roller bearing 7, an input small flange 8, an input flange 9, an oil seal 10, an output flange 11, an elastic retainer ring for a shaft 12, a distance ring 13, an upper cover 14 and a vent cap 15.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

All the electrical components in the present application are connected with the power supply adapted to the electrical components through a wire, and an appropriate controller and an appropriate encoder should be selected according to actual conditions to meet control requirements, and specific connection and control sequences should be obtained.

The embodiment is as follows: according to the attached figures 1-2 of the specification, the compact spiral bevel gear commutator comprises an output shaft 4 and an input shaft 3, wherein two sides of the outer wall of the output shaft 4 penetrate through an output flange 11 and a tapered roller bearing 7 from outside to inside to output a spiral bevel gear 2, the output flange 11 is fixed on a shell 5 through bolts, the two sides of the output shaft 4 are identical in structure, two sides of the outer wall of the input shaft 3 on one side sequentially penetrate through an input flange 9, a double-row angular contact bearing 6, an input small flange 8, a distance ring 13, an input spiral bevel gear 1 and a shaft elastic check ring 12 from outside to inside to be connected through a clamp spring, two ends of the pair of input spiral bevel gears 1 and the pair of output spiral bevel gears 2 are clamped to form a square, the input spiral bevel gears 1 drive the output spiral bevel gears 2 to rotate, so that the input shaft is rotated, the output shaft is rotated by power, and the transmission of the power is completed. The input shaft 3 is connected with the input spiral bevel gear 1 in a key mode. The input flange 9 and the input small flange 8 clamp the double-row angular contact bearing 6. The input flanges 9 on both sides of the output shaft 4 are not in accordance with the type of the input small flange 8. Different sizes are adopted according to the connecting structure. The output flange 11 and the input flange 9 are provided with oil seals 10. To ensure the sealing effect. A vent cap 15 is provided on the upper cover 14 of the housing 5. Prevent that the pressure that the air inflation produced can't discharge, can dispel the heat simultaneously.

The operation process comprises the following steps: the input shaft may be coupled to various power sources by keyed couplings. The output shaft may be coupled to various work machines by keyed couplings. The input shaft is rotated, the output spiral bevel gear 2 is driven by the input spiral bevel gear 1, so that the output shaft starts to rotate by power, and the power transmission is completed. The input shaft at the other side is in a follow-up state. In the process of high-speed rotation power transmission, certain heat is generated along with the contact of the spiral bevel gear, so that internal lubricating oil and air can be expanded. The inside of the speed reducer shell is in a sealed state, and the internal air expansion is solved by a 15-ventilation cap arranged on the upper cover 14. The output shafts of the single and double input shafts can be replaced according to the installation requirement; the input flange and the output flange are replaced.
