Technical solution of the present utility model is: this speed reducer comprises housing, the one-level gear shaft, the secondary pinion shaft, three grades of pinion shafts and output shaft, one-level gear shaft and output shaft are installed on the housing by coaxial bearing, two or three grade of pinion shaft is symmetrically located at the both sides of one-level gear shaft and output shaft on housing by Bearing Installation, between one-level gear shaft and three grades of pinion shafts, the secondary pinion shaft is set, the secondary pinion shaft by bearings on housing, one-level small gear on the one-level gear shaft and the engagement of the one-level gearwheel on the secondary pinion shaft, three grades of small gears in the secondary gearwheel engagement on secondary small gear on the secondary pinion shaft and the three grades of pinion shafts, three grades of pinion shafts mesh with three grades of gearwheels on the output shaft.
In the novel tertiary centre transmission speed reducer of the present utility model, the one-level small gear is installed on the one-level gear shaft, the one-level small gear is the cylinder double helical gear that helix angle equates, rotation direction is opposite, and the one-level small gear meshes two one-level gearwheels respectively.
In the novel tertiary centre transmission speed reducer of the present utility model, the one-level gear shaft is supported on the housing by axial unconfined roller bearing.
In the novel tertiary centre transmission speed reducer of the present utility model, secondary pinion shaft, three grades of pinion shafts are tooth, axle single piece, the one-level gearwheel is connected on the secondary pinion shaft by bulging joining sleeve, the secondary gearwheel connects with three grades of pinion shafts by key, two three grades of pinion shafts simultaneously with output shaft on three grades of gearwheels mesh simultaneously.
The utlity model has following advantage: 1. this speed reducer one-level gear shaft adopts the cylinder double helical gear that the two ends helix angle equates, rotation direction is opposite to drive two fens branch roads of two one-level gearwheels formation respectively, realizes power dividing; 2. the one-level gear shaft is supported on the housing by axial nothing constraint roller bearing, when load operation, because of the circular pitch cumulative departure of tertiary gear can cause the single channel engagement, can push a side gear of one-level gear shaft to opposite side this moment, make another branch road obtain engagement, so move in circles, the constantly reciprocal play of one-level gear shaft, two branch roads engagement compensation mutually obtains all to carry; 3. the secondary pinion shaft of this speed reducer, three grades of pinion shafts all adopt tooth, axle single piece, and manufacture cost is relatively low, and tissue production is easier to; 4. this tertiary centre transmission speed reducer carrying scope is big, gear range is big, transmission efficiency is high, user cost is lower, can be widely used in building material industry and mining industry and basic energy resource industry.
