Technical problem to be solved by this invention is, a kind of gearbox of engineering machine is provided, and by strengthening module, improves the velocity ratio of associated gear and also selects suitable gear shaft for use, improves its combination property, in order to overcome the defective of above-mentioned existing like product.
The technical solution adopted for the present invention to solve the technical problems is as follows:
A kind of gearbox of engineering machine, one shaftgear is fixed on first, high gear and low speed gear are fixed on second by spacer, a high gear and a shaftgear often mesh, and reverse gear is fixed on second, pay the speed change shifting slide gear, two, fourth gear and, three-range transmission are contained on the 3rd, two, fourth gear shifting slide gear and one or three reverse gear shifting slide gears are contained on the 4th, and the deceleration gearwheel is fixed on the 5th, often mesh with the 4th fixed gear.
The velocity ratio of one shaftgear and high gear is 1: 1.3-1.5, preferred 1: 1.4; High gear is 1.7-1.5 with the velocity ratio of paying speed change shifting slide gear small end: 1, and preferred 1.647: 1; Low speed gear is 1 with the velocity ratio of paying the big end of speed change shifting slide gear: 1.4-1.6, preferred 1: 1.5; One, the velocity ratio of the bigger end of three-range transmission and one or three reverse gear shifting slide gears is 1: 1.25-1.45, preferred 1: 1.388; Two, the velocity ratio of fourth gear and two, fourth gear shifting slide gear is 1.8-2.0: 1, and preferred 1.941: 1; The velocity ratio of gear shaft and deceleration gearwheel is 1: 3-4.5, and, preferred 1: 3.266 or 1: 3.923; The velocity ratio than small end of reverse gear and one or three reverse gear shifting slide gears is 1.0-1.2: 1, and preferred 1.1: 1.
Second and the 3rd adopt six keys, 36 millimeters of outer diameters, 31 millimeters of inner diameters, key wide eight millimeters; The 4th is adopted six keys, 40 millimeters of outer diameters, 35 millimeters of inner diameters, wide ten millimeters on key.
Good effect of the present invention is: the number of teeth of associated gear, velocity ratio design science, therefore, each gear speed is reasonable, not only saves power, and has improved working efficiency.In addition, the design alternative of gear shaft more meets product requirement, has improved the product combination property, has prolonged the working life of gearbox.
