The model utility content
The purpose of the utility model is to provide the oil hydraulic motor of a kind of band brake module and retarder; This device is with drive motor and the integrated transmission device of retarder, and it is big to have solved the old product discharge capacity, the defeated little defective of moment of torsion; Adopt modularization self-controlled type mechanical braking simultaneously; Improve the efficient of swivel gear, braked more reliably, solved the problem that exists in the existing technology.
For addressing the above problem, the technological scheme that the utility model is taked is:
The oil hydraulic motor of a kind of band brake module and retarder; Described oil hydraulic motor comprises drive motor, the retarder that is connected with drive motor and brake module; Described brake module is installed in the middle of drive motor and the retarder; Said retarder comprises the central gear of one-level planetary reduction gear and is meshed with the one-level planet wheel and the double output flange of making drive unit of its engagement; Said brake module comprises butterfly spring, moving block and friction plate group, and the central gear of described friction plate group and one-level planetary reducer and mounting plate engagement.
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; Described butterfly spring is installed in the drive motor right side, and through the force moving block and the friction of friction plate group of butterfly spring, the friction plate group is through the central gear engagement of interior external tooth and mounting plate and one-level planetary reduction gear.
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. by self-controlled type brake module braking, reduced and added external control brake control oil channel or equilibrium valve group in addition, simple in structure, improved the efficient of swivel gear.
2. 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.
3. through changing oil hydraulic motor, can realize different output torques easily with a series of different displacements.
4. oil hydraulic 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.
