The invention belongs to the field of mining hydraulic motors, and especially discloses a same-distribution-angle
hydraulic cylinder motor. A technical problem to be solved is providing a same-distribution-angle
hydraulic cylinder motor with the advantages of simple structure, operation convenience, high
safety coefficient, long service life and effective reduction of the
coal mine underground accident rate. The motor comprises a case body, three hydraulic cylinders, a
crankshaft, a case body front end
assembly and a
control system, the whole case body is a shell structure, the three hydraulic cylinders are arranged in the case body side by side, the front end of the case body is provided with a case body semicircle seat for installing the
crankshaft, the case body front end
assembly is fixedly connected with the case body to fix the
crankshaft, the
piston terminals of the hydraulic cylinders are connected with the crankshaft through
piston terminal covers, the hydraulic cylinders move back and forth to drive the crankshaft to rotate, the crankshaft drives the
control system to move, and the
control system controls the
reciprocating motion of the three hydraulic cylinders in order to drive the crankshaft to continuously revolve. The motor adopting the hydraulic cylinders to drive the crankshaft to rotate has the advantages of low rotating speed, large torque, and suitableness for the use requirements of
coal mine underground equipment.
