Abstract
The utility model relates to a hydraulic motor in integrated transmission with a reducer. The hydraulic motor in integrated transmission with the reducer comprises a driving motor and the reducer which is connected with the driving motor, wherein the reducer comprises a center gear with primary planetary speed reduction, a primary planet wheel meshed with the center gear, and an output flange which is taken as a driving device and is meshed with the primary planet wheel. The hydraulic motor in integrated transmission with the reducer has the beneficial effects that the structure is simple, the efficiency of a rotation device is improved, the final output torque is large, the displacement is small, and the impact of external force on the hydraulic motor is reduced, therefore, the service life of the hydraulic motor is prolonged, and the maintenance time is saved.
Description
Technical field
The utility model relates to a kind of swivel gear, relates in particular to a kind of oil hydraulic motor that is applied to the swivel gear of mining machinery or engineering machinery.
Background technique
The walking swivel gear that is applied at present mining machinery or engineering machinery on the market generally all directly drives with oil hydraulic motor; Its defective is that discharge capacity is big, and output torque is little, and the oil hydraulic motor impact resistance is poor; Produce back pressure with the braking of equilibrium valve group and reduced swivel gear efficient, the braking poor reliability.
The model utility content
The purpose of the utility model is to provide the oil hydraulic motor of a kind of oil hydraulic motor and the integrated transmission of retarder; Be mainly used in mining machinery or the engineering machinery; This device is with Hydraulic Motor and Integrated Reducer Driving Device, and it is big to have solved in the existing technology product discharge capacity, the defeated little technical problem of moment of torsion.
For addressing the above problem, the technological scheme that the utility model is taked is:
A kind of oil hydraulic motor of and the integrated transmission of retarder; Described oil hydraulic motor comprises drive motor, the retarder that is connected with oil hydraulic motor, and said retarder comprises the central gear of one-level planetary reduction gear and reaches with the one-level planet wheel of its engagement and is meshed with the double output flange of making drive unit.
Technological scheme further is:
Described mounting plate is used for fixing whole oil hydraulic motor; The left end dress drive motor of mounting plate; Dispose the central gear of the one-level planetary reduction gear of retarder at the right-hand member of drive motor; Described one-level planet wheel is contained in the right-hand member of output flange, with the central gear engagement of one-level planetary reducer, and the internal tooth engagement of described one-level planet wheel and output flange; Output flange is fixed on the mounting plate through first deep groove ball bearing and second deep groove ball bearing.
Said drive motor is connected with the central gear of one-level planetary reduction gear through the splined hole of its axle head, and the central gear of one-level planetary reduction gear is given the one-level planet wheel with transmission of power, and one-level planet wheel and output flange engagement make the output flange rotary work.
Adopt the beneficial effect that technique scheme produced to be:
1. form swivel gear by drive motor and retarder, final output torque is big, discharge capacity is little, has reduced the impact of external force to oil hydraulic motor, has improved oil hydraulic motor working life greatly.
2. through changing hydraulic drive motor, can realize different output torques easily with a series of different displacements.
3. drive motor and retarder are two relatively independent modules, and when one of them module appearance damage, only this module of integral replacing has been practiced thrift engineering time.
