Abstract
The utility model relates to a transmission mechanism of a final drive of a helicopter. The transmission mechanism comprises a final drive input driving bevel gear, a gear shaft and a tail output driven bevel gear; a transmission gear is fixedly arranged on the gear shaft; the transmission gear comprises an installing structure and a gear disc; bevel teeth are processed on the end part of the gear disc, divided into two parts and distributed on two sides of the end part of the gear disc; one part of the bevel teeth is engaged with the final drive input driving bevel gear and the other part is engaged with the tail output driven bevel gear; and the transmission gear is installed on the gear shaft by the installing structure. According to the utility model, numbers of gear parts of a final drive are reduced, and an integrated gear processing technique is adopted, so difficulty levels of installing and debugging of the final drive can be effectively reduced and objectives of easy maintenance and use, and reduction in height and size of the final drive are achieved.
Description
Technical field
The utility model relates to a kind of driving mechanism, especially a kind of main reducing gear driving mechanism.
Background technique
In traditional Helicopter Main Reducer structure, main subtracting comprises input drive bevel gear, input driven wheel of differential, tail output driving gear and four kinds of bevel gears of tail output driven wheel of differential.Major function is that the rotating speed of motor and power are passed to rotor and tailing axle.The power that concrete transmission circuit is motor and rotating speed are delivered to gear shaft by input drive bevel gear and input driven wheel of differential, gear shaft fixing input driven wheel of differential and tail output driving gear, gear shaft and planetary system acting in conjunction are delivered to rotor by rotating speed and power.Tail output driving gear and tail output driven wheel of differential are delivered to tailing axle by rotating speed and power.Input driven gear and tail are exported driving gear and are arranged on gear shaft, reach the object that input speed and power is delivered to rotor shaft and tailing axle, and concrete structure is shown in Fig. 1.These structure component are more, complex structure, and part takes up room larger.Need to main subtract input gear secondary with tail output gear wheel set totally four gears adjust respectively installation, cause main reducing gear to install, debug and safeguard inconvenience.
Summary of the invention
The purpose of this utility model be to provide a kind of simple in structure, amount of parts is few, is easy to the driving mechanism of adjusting and installing.
The technical solution of the utility model is that mechanism comprises main reducing gear input drive bevel gear, gear shaft, tail output driven wheel of differential.On described gear shaft, be installed with driving gear, driving gear comprises mounting structure and gear disk, the end of gear disk is processed with cone tooth, described cone tooth is two-part the both sides that are distributed in gear disk end, a part and the engagement of main reducing gear input drive bevel gear, another part and the engagement of tail output driven wheel of differential, driving gear is arranged on gear shaft by mounting structure, and described driving gear is to be arranged on gear shaft by bolt.
The utility model subtracts input driven gear and the integrated design of tail output driving gear by master, the gear of integrated design is arranged on gear shaft, met the main installation requirement that subtracts bevel gear and tail-rotor drive bevel gear, this model utility will reduce Driven Gear of Final Reduction Gear number of spare parts, by integrated Gearmaking Technology, control, can effectively reduce main reducing gear installation, debugging difficulty, reach and safeguard the main object that subtracts height dimension of easy to use, reduction.
Accompanying drawing explanation
Fig. 1 is conventional helicopters main reducing gear driving mechanism;
Fig. 2 is structural representation of the present utility model.
Embodiment
As shown in the figure, Helicopter Main Reducer driving mechanism comprises main reducing gear input drive bevel gear 1, gear shaft 2, tail output driven wheel of differential 3.On described gear shaft 2, be installed with driving gear 4, driving gear 4 comprises mounting structure and gear disk, the end of gear disk is processed with cone tooth, described cone tooth is two-part the both sides that are distributed in gear disk end, a part and main reducing gear input drive bevel gear engagement 1, another part and 3 engagements of tail output driven wheel of differential, driving gear is arranged on gear shaft 2 by mounting structure, and described driving gear is to be arranged on gear shaft 2 by bolt 4.
