Embodiment Construction
[0033] Below in conjunction with embodiment, further illustrate the present invention.
[0034] see Figure 1-Figure 4 It can be seen that a radial multi-cylinder hydraulic motor of the present invention is composed of a motor body 1 and a hydraulic cylinder 3 that drives the motor body 1; Connected into one body; the motor rotor rotates along the bearing 5; a plurality of hydraulic cylinders 3 are installed at intervals along the circumference of the motor body 1, the rear end of the hydraulic cylinder 3 is hinged to the motor body 1, and the turntable 2 of the motor rotor is arranged in an equilateral polygonal shape. The outer surface of the turntable 2 is equidistantly provided with grooves 9 along the circumferential direction. The number of grooves 9 corresponds to the number of hydraulic cylinders 3. When the piston rod at the front end of the hydraulic cylinder 3 is stretched out, the end of the piston rod pushes into the groove 9. Pushing the rotor to rotate, the out...

The invention discloses a radial multi-cylinder hydraulic motor, which comprises a motor body and a hydraulic oil cylinder for driving the motor body. The middle part of the motor body is equipped with a bearing assembly and a motor rotor, and the motor rotor is integrally composed of a rotating shaft and a turntable; The motor rotor rotates along the bearing; multiple hydraulic cylinders are installed at intervals along the circumference of the motor body. The rear end of the hydraulic cylinder is hinged with the motor body. The number of grooves corresponds to the number of hydraulic cylinders. When the piston rod at the front end of the hydraulic cylinder is stretched out, the end of the piston rod pushes into the groove to push the rotor to rotate. The outer wall of the cylinder body of the hydraulic cylinder is provided with a pushing mechanism. The pushing mechanism pushes the piston rod of the hydraulic cylinder close to the turntable. The structure of the device is relatively simple, there are no high-speed running parts, it is resistant to overload, and has obvious cost advantages.
Description
technical field [0001] The invention relates to a hydraulic device, specifically a radial multi-cylinder hydraulic motor. Background technique [0002] At present, hydraulic cylinders have been widely used in various engineering fields, and with the development of technology, the demand for low-speed, high-torque, and large-displacement hydraulic cylinders is increasing. So far, low-speed, high-torque, large-displacement hydraulic cylinders mostly use connecting rod hydraulic cylinders. [0003] As disclosed in CN 202789314U's "A Hydraulic Cylinder", a connecting rod type single-acting 18-piston cylinder double row radial motor. There are also multi-acting internal curve motors. However, the former hydraulic cylinder has a large outline size and a large pressure and flow pulsation. The latter has the defects of complex structure, large contact stress of the working part, large lateral force, short life and high processing cost. On the other hand, when the inner curve moto...
