Hydraulic motor_1

"In an area of hydraulic motors there are different types of motors with vanes, pistons, screws, gears and so forth that use pressurized liquids for rotating output shaft. The all known hydraulic motors designs have deficiencies in having complex design, low effective ratio torque - weight of motors and most of them have intermediate mechanisms that transfer linear to rotary motion of motor output shaft. There are vane type motors with vanes having linear reciprocation motions during its rotation that is considering as a weakest place of hydraulic motor design. The gear hydraulic motor has low ratio of torque - weight that cannot be useful in some areas of engineering. New rotor type hydraulic motor is capable of converting pressurized fluid energy directly into rotary motion. Theoretical calculated results shows that the new design outperformed (the ratio torque/weight) conventional hydraulic motors above 30 times. This was possible by use the principle of overrunning roller clutch and its incorporation into the motor design.
New vane type hydraulic motor is capable of converting pressurized fluid energy directly into rotary motion of output shaft and can transfer big torque. This was possible by use the principle of overrunning roller or tooth-cam clutches and their incorporation into the motor design. The motor has two sections with four bushed vanes, which connect with output shaft by eight reciprocation clutches. Each section works separately and torque is transferred to the shaft by sections consequently from first section to second section and then from second section to first section without stops of the output shaft.

Reciprocation roller clutch

Area application of the invention reciprocation roller clutch is mechanisms and machines in engineering. Known standard reciprocation roller clutches designed with cylindrical rollers, which axis are parallel to axis of the hub and shaft. This design of the clutch increases the diametrical size one due to location of two hubs, which one is inner and second is outer. In many cases some times this property of known clutches does not allow to use in engineering. Proposed invention the reciprocation roller clutch has different design where rollers locate facially to hubs of the clutch. Such design has less diametrical size and can be used for mechanisms and machines with restricted diametrical dimensions.
