Fig. 2 is that A-A among Fig. 1 is to cutaway view.
Fig. 3 is the constructional drawing of the single chain link in the existing chain.
The specific embodiment
Below in conjunction with concrete accompanying drawing and embodiment the present invention is described further.
Sprocket shaft 1 structure such as Fig. 1, shown in Figure 2 of said electric chain hoist; Be followed successively by left end shaft cushion cap 3, chain Luntai 2, sealing platform 4, gear positioning table 5 and right-hand member bearing stand 7 on the sprocket shaft 1 from left to right; Be used to install bearing on the said left end shaft cushion cap 3 right-hand member bearing stands 7, so that sprocket shaft 1 is installed in the casing of electric chain hoist; Said sealing platform 4 is used to install seal ring, is used to install the gear of transferring power on the said gear positioning table 5, and gear positioning table 5 is provided with positioning spline 6, passes through the key transfer torque between gear and the sprocket shaft 1; The periphery of said chain Luntai 2 is the sprocket wheel tip circle; The sprocket wheel tip circle is provided with five five five equilibrium tip circle planes 8; Be concaved with sprocket wheel eye socket 9 in each five five equilibrium tip circle plane 8, said sprocket wheel eye socket 9 is used to carry the chain link that keeps flat, and is sprocket teeth 10 between the adjacent five five equilibrium tip circle planes 8; Said chain Luntai 2 is provided with circular groove 14 at the midway location of its Width; The bottom of said circular groove 14 for sprocket wheel at the bottom of the circle; Circle is provided with disk 12 at the bottom of five five five equilibriums at the bottom of the sprocket wheel; Said circular groove 14 is used to set the chain link of placing vertically, the straight flange of the said chain link of placing vertically corresponding disk 12 at the bottom of five five equilibriums; Disk 12 is uniformly distributed with at the circumferencial direction of chain Luntai 2 at the bottom of described five five five equilibrium tip circle planes 8 and five five five equilibriums, and the vertical center line of disk 12 is 36 ° of angles at the bottom of the vertical center line on each five five equilibrium tip circle plane 8 and the five adjacent five equilibriums.
