Abstract
The utility model discloses a novel speed reducer of a double shunt load-balancing central drive mill. The speed reducer comprises a housing, a first stage gearwheel shaft(5), first stage big gearwheels (1 and 6), second stage gearwheel shafts (3, 7), a second stage big gearwheel (8) and an output shaft (9), wherein the first stage gearwheel shaft(5) and the output shaft (9) are coaxially mounted on the housing through a bearing; the second stage gearwheel shafts (3 and 7) are mounted on the housing through the bearing and symmetrically arranged on the two sides of the first stage gearwheel shaft(5) and the output shaft (9); the first stage gearwheel shaft(5) is simultaneously engaged with the first stage big gearwheels (1 and 6) mounted on the second stage gearwheel shafts (3 and 7); and the second stage gearwheel shafts (3 and 7) is simultaneously engaged with the second stage big gearwheel (8) mounted on the output shaft (9). The novel speed reducer of double shunt load-balancing central drive mill not only can ensure that the manufacturing cost is rather lower and the investment is smaller, but also can ensure that the speed reducer is convenient to mount and maintain.
Description
Technical field
The utility model belongs to mechanical field, is specifically related to a kind of novel double split flow and all carries center transmission grinding machine speed reducer.
Background technique
The secondary center transmission grinding machine speed reducer of present domestic employing, main pattern is as follows: the one-level gear shaft meshes two one-level gearwheels simultaneously, and the one-level gearwheel is connected by torsion shaft with the secondary gear axle, utilizes the resiliently deformable of torsion shaft to realize all carrying; This torsion shaft load balancing structure is made complicated, and it is big to adjust difficulty, easily causes unbalance loading, the installation and maintenance inconvenience.
Summary of the invention
The purpose of this utility model is: design a kind of novel double split flow and all carry center transmission grinding machine speed reducer, both guaranteed that manufacture cost was relatively low, investment is less, guarantee to install and use easy to maintenance again.
Technical solution of the present utility model is: this speed reducer comprises housing, one-level gear shaft, one-level gearwheel, secondary gear axle, secondary gearwheel and output shaft, one-level gear shaft and output shaft are installed on the housing by coaxial bearing, two secondary gear axles are symmetrically located at the both sides of one-level gear shaft and output shaft on housing by Bearing Installation, the one-level gear shaft meshes with the one-level gearwheel that is installed on the secondary gear axle simultaneously, and secondary gear axle while and the secondary gearwheel that is installed on the output shaft mesh.
Center transmission grinding machine speed reducer is all carried in novel double split flow of the present utility model, the one-level gear shaft adopts the cylinder double helical gear that helix angle equates, rotation direction is opposite to drive two fens branch roads of two one-level gearwheels formation respectively, and the one-level gear shaft is supported on the housing by axial unconfined roller bearing; The secondary gear axle is tooth, axle single piece, and one of them one-level gearwheel is connected on the secondary gear axle by the swelling cover, and the secondary gearwheel on two secondary gear axles and the output shaft meshes simultaneously.
The utlity model has following advantage: 1. this speed reducer one-level gear shaft adopts the cylinder double helical gear that 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, by axial float, makes two branch roads engagement compensation mutually, obtains all to carry; 3. the secondary gear axle of this speed reducer adopts tooth, axle single piece, and cumulative error is little, and one of them one-level gearwheel is connected on the secondary gear axle by bulging joining sleeve, installs and uses easy to maintenance.
