In current high-power, the high speed Involutes Gears Transmission device, a kind of structural type is to adopt the involute planet gear transmission device, and another kind of structural type is to adopt three shunting involute diclinic gears to add torsion shaft to transfer synchronous transmission device.
Planetary type gear transmission unit is after the planet carrier linear velocity is greater than 20m/s, raising and transmission power that planetary pinion centrifugal force has just restricted the planetary type gear transmission unit rotating speed basically increase, so the general only suitable gear linear velocity of planetary pinion transmission is not more than the middle-size and small-size high-speed gear transmission device of 80m/s; Though three shunting involute diclinic gears add torsion shaft and transfer synchronous transmission device gear linear velocity can reach about 150m/s, it is bigger that transmission power can be done, but because the diclinic gear is to be processed respectively by two monocline teeth, bigger cumulative error must appear, kinematic accuracy and contact precision are reduced, the correction of the flank shape of gear is repaiied to also bad enforcement, and bearing capacity reduces greatly.
The model utility content
In view of this, the utility model provides a kind of three shunting high speed transmission gear-boxes, and to realize the bearing capacity height, the gear linear velocity reaches more than the 170m/s.
For achieving the above object, the utility model provides following technological scheme:
A kind of three shunting high speed transmission gear-boxes, comprise: casing, case lid, rolling bearing, high speed shaft, lower velocity shaft and shunting gear shaft, described lower velocity shaft and described high speed shaft match with case lid, casing respectively in the part insertion casing, described lower velocity shaft is provided with low speed gear, and described high speed shaft is provided with high gear; Being respectively arranged with the rolling bearing of 120 ° of angles of trisection on casing and case lid, matches with described rolling bearing in described shunting gear shaft two ends; Described shunting gear shaft quantity is three, and described low speed gear is meshed with three small gears of shunting on the gear shafts, and described high gear is meshed with three gearwheels of shunting on the gear shafts.
Preferably, above-mentioned three shunting high speed transmission gear-boxes are installed the gearwheel position and are provided with pin on the described shunting gear shaft.
Preferably, above-mentioned three shunting high speed transmission gear-boxes, the quantity of described pin is four.
Preferably, above-mentioned three shunting high speed transmission gear-boxes, described gear and bearing are flooding system lubrication.
Preferably, above-mentioned three shunting high speed transmission gear-boxes, described gear is involute monocline gear.
From above-mentioned technological scheme as can be seen, the utility model embodiment adopts three shunting gear shafts, make three axles transfer torque on the high speed shaft, stressed even, running is synchronous, stable working, its bearing capacity improves greatly, in addition owing to bearing capacity improves, so the also corresponding raising of gear linear velocity can reach 170m/s; Because profile of tooth is involute monocline tooth, the correction of the flank shape of gear is repaiied to also being convenient to enforcement, and centering also is convenient in assembling, and it is littler than diclinic tooth that the while axial dimension can be done, thereby saved the space, saved material, and boundary dimension reduces about 30%, and is in light weight more than 15%.
