Technical problem to be solved in the utility model is achieved by the following technical solution:
A kind of twin shaft cycloid hydraulic motor comprises the commentaries on classics stator pack that first housing and an end link to each other with first housing, and the other end of described commentaries on classics stator pack links to each other with second housing, and second housing links to each other with protecgulum; Rotor in the described commentaries on classics stator pack links to each other with second output shaft by couple axle, and the axle head of second output shaft convexedly stretches in outside the protecgulum.
In order to guarantee under join strength and the firm prerequisite, make material and weight reduce to minimum, the end that described second housing is connected with protecgulum evenly is provided with bolt hole, the wall thickness of each bolt hole forms a cylindrical body along the end portion thickness direction, adopts circular arc excessively to connect between two adjacent formed cylindrical bodys of bolt hole.
The external tooth engagement of the back segment of the internal spline of described rotor and couple axle front end, the internal spline engagement of the external tooth of the rear end of described couple axle and second output shaft.
In order to make motor can bear the bigger thrust load that radially reaches, be provided with needle bearing between described second output shaft and second housing.
Fastening in order to connect, reliable, the described protecgulum and second housing are fastenedly connected by screw.
In sum, the housing of the utility model redesign motor rear end, flange, the structure of connecting bolt and axle, the utility model provides more simple assembly technology, improves the manufacturing efficiency of motor, and the maintenance of the motor of being more convenient for, this structure has also improved the sealability of motor simultaneously, effectively prevents the joint seepage of the high pressure oil of motor inside from bolt.
Below in conjunction with the drawings and specific embodiments the technical solution of the utility model is described in detail.
