Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic motors, in particular to a hydraulic motor with a residue filtering function. Background Art

[0002] The hydraulic motor is an actuator of the hydraulic system, which converts the liquid pressure energy provided by the hydraulic pump into the mechanical energy (torque and speed) of its output shaft. Liquid is the medium for transmitting force and motion.

[0003] The inventors discovered during actual use that since the hydraulic oil that provides movement for the hydraulic motor is circulated, some debris in the pipes and chambers will be mixed with the hydraulic oil during the compression and flow of the hydraulic oil. Hydraulic oil with large particles of debris entering the hydraulic motor will cause blockage of the internal channels of the hydraulic motor. Utility Model Content

[0004] The utility model aims to solve the shortcomings in the prior art and proposes a hydraulic motor with a residue filtering function.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a hydraulic motor with a residue filtering function, comprising a hydraulic motor body, a liquid outlet pipe and a liquid inlet pipe are installed on the surface of the hydraulic motor body, a filter assembly is arranged at the port of the liquid inlet pipe, the filter assembly comprises a sleeve sleeved on the surface of the liquid inlet pipe, the hydraulic oil enters the hydraulic motor body from the sleeve through the liquid inlet pipe, a bracket is arranged between the sleeve and the liquid inlet pipe for fixing, and a filter module is arranged at the port of the liquid inlet pipe.

[0006] The effects achieved by the above components are as follows: the hydraulic generating unit (which can be a hydraulic pump) pumps high-pressure liquid from the inlet pipe into the hydraulic motor body, and the high-pressure liquid drives the rotor of the hydraulic motor body to rotate and is discharged from the outlet pipe. The filter module is fixed to the inlet pipe port through a sleeve, and then the sleeve is externally connected to the hydraulic generating unit. The oil passes through the filter module and is filtered by the filter module to prevent large particles of impurities in the oil from causing blockage of the internal oil circuit of the hydraulic motor body.

[0007] Preferably, the filter module comprises a filter bucket fixed at the liquid inlet pipe port, a filter ring is fixedly connected to the upper end of the outer ring of the filter bucket, and a filter cone is fixedly connected to the upper end of the filter ring.

[0008] The effects achieved by the above components are: the filter bucket, filter ring and filter cone made of metal filter are blocked at the liquid inlet pipe port, and the oil must pass through the filter bucket, filter ring and filter cone to enter the liquid inlet pipe. The metal filter can filter out large particles of debris in the oil.

[0009] Preferably, a cleaning assembly is provided on the surface of the filter cone, and the cleaning assembly includes a sweeping rod provided on the surface of the filter bowl, the upper end of the sweeping rod is rotatably connected to a spring, the upper end of the spring is rotatably connected to a mounting bracket, and the mounting bracket is installed inside the sleeve.

[0010] Preferably, a swivel is fixedly connected to the bottom surface of the sweep rod, a magnetic block is fixedly connected to the surface of the swivel, and a magnetic ring is rotatably connected to the surface of the sleeve.

[0011] The effects achieved by the above components are: the sleeve is made of transparent acrylic, and you can see through the sleeve to see if there is any debris adhering to the surface of the filter module. If there is, by rotating the magnetic ring, the inside of the magnetic ring and the magnetic block are attracted to each other, and the magnetic ring rotates, driving the magnetic block to move together. The magnetic block rotates on the rotating ring, and the sweeping rod on the upper part of the rotating ring slides on the surface of the filter bucket, and the brush on the surface of the sweeping rod cleans the debris on the filter bucket, thereby ensuring the passability of the filter bucket.

[0012] Preferably, a sliding groove is provided on the surface of the sleeve, and a magnetic ring is rotatably connected in the sliding groove.

[0013] The effect achieved by the above components is that the slide groove plays a role in limiting the position of the magnetic ring.

[0014] Preferably, a sealing device is arranged between the sleeve and the liquid inlet pipe for sealing, and the sealing device comprises a blocking ring. Two blocking rings are arranged, and the two blocking rings are respectively fixed on the surface of the sleeve and the liquid inlet pipe. A spacer ring is arranged between the sleeve and the liquid inlet pipe, and a bevel ring is fixedly connected to the bottom end of the spacer ring. Bolts are inserted into the side wall of the sleeve through threads, and the bolts are pushed upward by the bevel ring to squeeze the seal below the spacer ring.

[0015] The effect achieved by the above components is: when it is necessary to clean the stains inside the sleeve, first use the sweeping rod to sweep the dirt on the surface of the rate cone onto the spacer ring, and then loosen the bolt. At this time, the bottom of the spacer ring is no longer blocked and the spacer ring can slide from the sleeve port along the liquid inlet pipe. The partition slides out of the sleeve. At this time, the dirt on the surface of the partition can be cleaned and the inside of the sleeve can be brushed with a small brush. When installing the partition, insert the partition into the sleeve, and then turn the bolt. The bolt port squeezes the bevel ring at the bottom of the partition, prompting the bevel ring to push the partition to continuously move toward the blocking ring. The partition is squeezed on the blocking ring to seal the sleeve port.

[0016] Preferably, a sealing ring is fixedly connected to the upper end of the spacer ring, and the sealing ring is clamped between the two blocking rings.

[0017] The effects achieved by the above components are as follows: the role of the sealing ring is to improve the sealing effect between the spacer ring and the two blocking rings, thereby facilitating the sealing of the sleeve port.

[0018] Compared with the prior art, the advantages and positive effects of the utility model are:

[0019] In the utility model, the hydraulic generating unit (which can be a hydraulic pump) pumps high-pressure liquid into the hydraulic motor body from the liquid inlet pipe, and the high-pressure liquid drives the rotor of the hydraulic motor body to rotate and is discharged from the liquid outlet pipe. The filter module is fixed to the liquid inlet pipe port through a sleeve, and then the sleeve is externally connected to the hydraulic generating unit. The oil passes through the filter module and is filtered by the filter module to prevent the oil circuit inside the hydraulic motor body from being blocked due to large particles of impurities in the oil.
