Problems solved by technology

[0002] At present, in hydraulic machines that require low-speed rotation, and at the same time set other components at the center of rotation or require simultaneous movement and other compound motions, the usual solution is to install another motion mechanism to complete it, which results in increased Reduced the size of the equipment and energy consumption, and sometimes cannot be completed due to volume limitations
The existing technology generally adopts the structural form of oil distribution plates at both ends. The design and processing of the oil distribution mechanism such as the oil distribution plate of the hydraulic motor with this structure are relatively complicated, and the sealing problem when connecting with other hydraulic components is difficult to solve. Causes processing difficulty and processing cost to increase, so it is rarely used on the market

Abstract

The invention discloses a cam rotor hydraulic motor for distributing oil in an abdominal cavity. The cam rotor hydraulic motor comprises a shaft sleeve, and a left stopper, a concave surface cam rotor and a right stopper mounted on the shaft sleeve in sequence from left to right; a stator is fixed between the left stopper and the right stopper, and sleeves the concave surface cam rotor; a shell is fixed outside the stator, and is provided with a shell oil return joint, a blade oil inlet joint and a shell oil inlet joint; an annular oil return groove, an annular blade oil groove and an annular oil inlet groove are formed in the outer wall of the stator; multiple blade oil ways and blade cavities are axially formed in the inner wall of the stator; radial blade oil inlet holes are formed in the stator; double blades are arranged in the blade cavities; and multiple pressureless cavity oil return holes and pressure cavity oil inlet holes are formed in the stator in the radial direction. The cam rotor hydraulic motor adopts a structure form of distributing the oil in the abdominal cavity, replaces a complex oil distribution disc mechanism by the annular oil grooves and the oil holes, is simpler in design and machining, preferably solves the sealing problem of hydraulic parts, and improves the efficiency.

Description

technical field [0001] The invention relates to a low-speed rotary hydraulic motor, in particular to a cam rotor hydraulic motor suitable for abdominal cavity oil distribution in drilling and blasting engineering construction such as tunnels and mines. Background technique [0002] At present, in hydraulic machines that require low-speed rotation, and at the same time set other components at the center of rotation or require simultaneous movement and other compound motions, the usual solution is to install another motion mechanism to complete it, which results in increased It reduces the size of the equipment and energy consumption, and sometimes it cannot be completed due to the limitation of the volume. The existing technology generally adopts the structural form of oil distribution plates at both ends. The design and processing of the oil distribution mechanism such as the oil distribution plate of the hydraulic motor with this structure are relatively complicated, and th...
