Detailed Description
As shown in fig. 1 to 6, a heavy truck double-combination gear, it adopts brand-new structural design, adopt integrated into one piece's structural design, holistic intensity is better, can ensure cooperation precision each other when installing, and whole sealing stability when the erection joint is better, whole security when using is more reliable, the life-span when using is longer, can replace traditional concatenation gear structure of combining together to install and use, the durability of guarantee when using is stronger, its use can make the maintenance cost in later stage lower, efficiency during the installation is higher. The double-combined gear comprises a cylindrical first combined gear structure main body 1, wherein the lower end of the first combined gear structure main body 1 is provided with an integrally formed cylindrical second combined gear structure main body 2, and the two combined gear structure main bodies form a double-combined gear main body. Be equipped with the first cooperation that circumference evenly distributed on the outer face of cylinder of first composite gear structure main part 1 and connect combination groove 3, be equipped with the second cooperation that circumference evenly distributed on the outer face of cylinder of second composite gear structure main part 2 and connect combination groove 4, can cooperate with other gear structures when using and use. The upper end of first combination gear structure main part 1 is equipped with the first combination sealing connection stable trough 5 of obconic, the upper end of first combination gear structure main part 1 leans on the outside position to be equipped with the second combination sealing connection stable trough 6 of obconic, and the cooperation leakproofness of guarantee upper end position can carry out more firm combination to the axial assembly subassembly, and the whole security performance in the use can satisfy the user demand under the multiple application environment.
