Abstract
The utility model provides a high-speed hydraulic motor shell, comprising a housing body which forms a cylinder as a whole, wherein a cavity body is arranged at one end part of the housing body; bumps are evenly distributed at the lateral wall of the housing body; a through hole is arranged on each bump; the through holes are communicated with the cavity body; an axial hole is arranged at the other end face of the housing body; and the axle hole is communicated with the cavity body. The high-speed hydraulic motor shell provided by the utility model has the advantages of being small in volume, light in weight, simple in structure, good in manufacturability, and small in inertia; and the impact resistance of the hydraulic motor can be improved.
Description
Technical field
The utility model relates to a kind of oil hydraulic motor, particularly a kind of high-speed hydraulic motor housing.
Background technique
oil hydraulic motor refers to traditionally to export and rotatablely moves, the hydraulic energy that oil hydraulic pump is provided changes the energy conversion device of mechanical energy into, it is mainly used in injection machine, boats and ships, work the machine of raising, engineering machinery, building machinery, coal mine machinery, mining machinery, metallurgical machinery, ship machinery, petrochemical industry, harbour machinery etc., but traditional high-speed hydraulic motor torque ripple is larger, efficient is lower, starting torque less (be only 60% of rated torque---70%) and low-speed stability are poor etc., therefore need a kind of new high-speed hydraulic motor and housing that can overcome above defective of exploitation.
The model utility content
