Embodiment
In order to make the purpose of this utility model, technological scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
As shown in Figure 1, the utility model discloses the protective gear of shaft drive equipment, it comprises transmission case 1, transmission shaft 7, gear assembly, fixing-assembly, elastic component, fitting and position limit switch 8, wherein:
Gear assembly comprises driving gear 3 and driven gear 4.As shown in Figure 2, driving gear 3 comprises hollow shaft 31 and engaging tooth 32, and engaging tooth 32 is distributed in the axial end of hollow shaft 31.Driven gear 4 comprises hollow shaft 41 and engaging tooth 42, and engaging tooth 42 is distributed in the axial end of hollow shaft 31.Driving gear 3 and driven gear 4 are coaxial transmission. Engaging tooth 31,41 is arc-shaped gear.
As described in Figure 2, transmission shaft 7 surfaces are provided with many axial notches 71, and hollow shaft 41 internal surfaces of driven gear 4 are provided with the raised line 411 matching with groove 71.Raised line 411 and groove 71 fasten, and driven gear 4 is in axial sliding connection with transmission shaft 7.
