Description

Technical Field

[0001] This utility model relates to the field of hydraulic motor technology, specifically to a high-pressure planar distribution cycloidal hydraulic motor. Background Technology

[0002] Cycloidal hydraulic motors, as a type of low-speed, high-torque motor, have been widely used in many fields such as industry and agriculture due to their advantages such as small size, high power density, high efficiency, and wide speed range.

[0003] However, in current planar distribution cycloidal hydraulic motors, the hydraulic oil entering the motor often contains impurities. These impurities can enter the internal components of the hydraulic motor along with the oil flow, potentially exacerbating wear between parts and causing scratches, peeling, and other damage to the surface of the parts. This can affect the normal operation of the hydraulic motor and, in severe cases, even damage the internal components. Utility Model Content

[0004] In view of the problems existing in the above-mentioned high-pressure planar distribution cycloidal hydraulic motors, this utility model is proposed.

[0005] Therefore, the purpose of this invention is to provide a high-pressure planar distribution cycloidal hydraulic motor, which solves the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A high-pressure planar distribution cycloidal hydraulic motor includes a hydraulic motor body. An oil inlet and an oil outlet are respectively provided on both sides of the upper surface of the tail end of the hydraulic motor body. An oil inlet shell is fixedly installed on the upper side of the oil inlet, and an oil outlet shell is fixedly installed on the upper side of the oil outlet. Through holes are provided at both ends of the oil inlet and oil outlet shells. A filter screen shell is rotatably installed inside the oil inlet shell and above the corresponding through hole. An oil inlet pipe and an oil outlet pipe are fixedly installed in the through holes at the top of the oil inlet and oil outlet shells, respectively. A scraper is fixedly installed on one inner wall of the oil inlet shell, with one side of the scraper abutting against the outer wall of the filter screen shell. A first transmission rod is rotatably sleeved on the side of the oil inlet shell away from the scraper. A first transmission mechanism is provided at one end of the first transmission rod to drive the filter screen shell to rotate. A second transmission mechanism is provided inside the oil inlet pipe to drive the first transmission rod to rotate.

[0008] Preferably, the first transmission mechanism includes a first bevel gear and a second bevel gear. The first bevel gear is fixedly sleeved on the upper outer wall of the filter screen housing, and the second bevel gear is fixedly sleeved on one end of the first transmission rod located inside the oil inlet housing. The first bevel gear and the second bevel gear are meshed together.

[0009] Preferably, the second transmission mechanism includes a second transmission rod and an impeller. The second transmission rod is rotatably sleeved inside the oil inlet pipe, and the impeller is fixedly sleeved on the rod wall of the second transmission rod. One end of the second transmission rod extends to the outside of the oil inlet pipe. A first spur gear is fixedly sleeved on the outer end of the first transmission rod, and a second spur gear is fixedly sleeved on the outer end of the second transmission rod. The first spur gear and the second spur gear are meshed together.

[0010] Preferably, the scraper is a wear-resistant rubber strip.

[0011] Preferably, the middle end of the first transmission rod is rotatably connected to the inner wall of the oil inlet shell through a first sealed bearing.

[0013] Preferably, the bottom of the filter screen housing is rotatably connected to the bottom inner wall of the oil inlet housing via a third sealed bearing.

[0014] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0015] This invention introduces hydraulic oil through an oil inlet pipe, which drives the impeller to rotate, causing the second transmission rod to rotate. This rotation is then transmitted through the first and second spur gears, which in turn causes the first transmission rod to rotate. The first transmission rod, through the transmission of the first and second bevel gears, drives the filter screen to rotate. The scraper strips, which are relatively fixed to the filter screen, rotate, ensuring that the scraper strips can continuously scrape and clean the outer wall of the filter screen, effectively preventing the accumulation of impurities and maintaining smooth oil supply.

[0022] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0023] This utility model discloses a high-pressure planar distribution cycloidal hydraulic motor.

[0024] Reference Figure 1-3 A high-pressure planar distribution cycloidal hydraulic motor includes a hydraulic motor body 1. An oil inlet 6 and an oil outlet 7 are respectively opened on both sides of the upper surface of the tail end of the hydraulic motor body 1. An oil inlet shell 2 is fixedly installed on the upper side of the oil inlet 6, and an oil outlet shell 3 is fixedly installed on the upper side of the oil outlet 7. Through holes are opened at both ends of the oil inlet shell 2 and the oil outlet shell 3. A filter screen shell 9 is rotatably installed inside the oil inlet shell 2 and above the corresponding through hole. The bottom of the filter screen shell 9 is rotatably connected to the inner wall of the bottom end of the oil inlet shell 2 through a third sealing bearing. The top of the oil inlet shell 2 and the oil outlet shell 3... An oil inlet pipe 4 and an oil outlet pipe 5 are fixedly installed in the through hole. A scraper 8 is fixedly installed on one side of the inner wall of the oil inlet shell 2. The scraper 8 is a wear-resistant rubber strip. One side of the scraper 8 abuts against the outer wall of the filter screen shell 9. A first transmission rod 11 is rotatably sleeved on the side of the oil inlet shell 2 away from the scraper 8. The middle end of the first transmission rod 11 is rotatably connected to the inner wall of the oil inlet shell 2 through a first sealed bearing. A first transmission mechanism that drives the filter screen shell 9 to rotate is provided at one end of the first transmission rod 11. A second transmission mechanism that drives the first transmission rod 11 to rotate is provided inside the oil inlet pipe 4.

[0025] Reference Figure 1-3 The first transmission mechanism includes a first bevel gear 10 and a second bevel gear 12. The first bevel gear 10 is fixedly sleeved on the upper outer wall of the filter screen housing 9, and the second bevel gear 12 is fixedly sleeved on one end of the first transmission rod 11 located inside the oil inlet housing 2. The first bevel gear 10 and the second bevel gear 12 are meshed and connected.

[0026] Reference Figure 1-3The second transmission mechanism includes a second transmission rod 14 and an impeller 15. The second transmission rod 14 is rotatably sleeved inside the oil inlet pipe 4, and the impeller 15 is fixedly sleeved on the rod wall of the second transmission rod 14. Both ends of the second transmission rod 14 are rotatably connected to the inner wall of the oil inlet pipe 4 through a second sealed bearing. One end of the second transmission rod 14 extends to the outside of the oil inlet pipe 4. A first spur gear 13 is fixedly sleeved on the outer end of the first transmission rod 11, and a second spur gear 16 is fixedly sleeved on the outer end of the second transmission rod 14. The first spur gear 13 and the second spur gear 16 are meshed together.

[0027] In this invention, during use, hydraulic oil enters the oil inlet shell 2 through the oil inlet pipe 4. The flowing hydraulic oil impacts the impeller 15, driving the second transmission rod 14 to rotate. The second spur gear 16 at the end of the second transmission rod 14 meshes with the first spur gear 13 on the first transmission rod 11, transmitting power to the first transmission rod 11 and causing the first transmission rod 11 to rotate synchronously.

[0028] When the first transmission rod 11 rotates, the second bevel gear 12 at its end meshes with the first bevel gear 10 at the upper end of the filter screen 9, driving the filter screen 9 to rotate around its own axis within the oil inlet shell 2. When the hydraulic oil flows through the filter screen 9, impurities are trapped by the filter screen 9, and the filtered hydraulic oil enters the hydraulic motor body 1 through the oil inlet 6.

[0029] During the rotation of the filter screen housing 9, the scraper 8 on the inner wall of the oil inlet housing 2 is always in contact with the outer wall of the filter screen housing 9, continuously scraping away impurities attached to the surface of the filter screen housing 9, preventing impurities from clogging the filter screen and affecting the oil supply efficiency. The scraper 8 is made of wear-resistant rubber material, which can ensure the cleaning effect without damaging the filter surface of the filter screen housing 9;

[0030] After the hydraulic motor body 1 has been in operation, the hydraulic oil is discharged from the oil outlet 7 and flows out through the oil outlet shell 3 and the oil outlet pipe 5. The first sealed bearing, the second sealed bearing and the third sealed bearing respectively ensure the sealing of the first transmission rod 11, the second transmission rod 14 and the filter screen shell 9 when they rotate, and prevent hydraulic oil leakage.

[0031] The entire filtration and cleaning process requires no additional power source. It is driven by the kinetic energy of the hydraulic oil itself, which enables continuous filtration of impurities and automatic cleaning of the filter screen. This effectively prevents impurities from entering the hydraulic motor and aggravating component wear, thus extending the service life of the hydraulic motor.

[0032] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
