TokyoKeiki CR-10-4PT4-30-SD-JA-S146-J Internal Gear-type low-speed High-torque Motor
TokyoKeiki CR-10-4PT4-30-SD-JA-S146-J internal gear-type low-speed high-torque motor is suitable for petroleum-based hydraulic fluids, with a displacement of 10 cm3/rev. The mounting method of TokyoKeiki is bolt flange, and the piping method is RC1/2 threaded port piping on the valve body side. It includes a tachometer mounting port (standard), and the shaft end type is a square key parallel shaft (1-1/4"). The rotation direction (viewed from the shaft side) is counterclockwise when fluid enters port A (clockwise when entering port B). The distribution valve uses a low-pulsation spool. An Rc1/8 external drain port is located on the same face as the main ports.
The TokyoKeiki CR-10-4PT4-30-SD-JA-S146-J hydraulic motor has a displacement of 167 cm3/rev, a rated operating pressure of 16 MPa, and a maximum operating pressure of 21.5 MPa. The rated flow rate is 60 L/min, and the maximum flow rate is 80 L/min. The rated torque is 380 N·m, and the maximum torque is 505 N·m. The rated speed is 300 rpm, and the maximum back pressure is 7 MPa.
Hydraulic Motor Selection Method:
Select a hydraulic motor model that meets the three conditions of pressure difference, speed, and required torque by referring to the characteristic curve. For example, a hydraulic motor that satisfies a pressure difference of 10.5 MPa, a speed of 300 rpm, and a required torque of 240 N·m is the CR-10. Additionally, it can be determined that the necessary flow rate under these conditions is 53 L/min.
