Description

Technical Field

[0001] This utility model relates to the field of piston motor technology, and in particular to a piston motor equipped with a reduction mechanism. Background Technology

[0002] A piston motor is a type of hydraulic motor. It uses hydraulic oil as a working medium to act on the piston or plunger end face, causing the piston or plunger to make linear reciprocating motion. Then, through a motion conversion mechanism, the reciprocating motion of the plunger is converted into the circular motion of the output shaft. A piston motor equipped with a reduction mechanism is a hydraulic component that integrates the reduction mechanism and the piston motor into one unit.

[0003] Existing piston motors have a relatively simple structure. During operation, the piston motor generates heat due to internal friction and hydraulic oil flow resistance. When too much heat accumulates, it will affect the performance and lifespan of the piston motor. At the same time, the hydraulic medium often contains contaminants, which cause abrasive wear on the piston motor parts. Frequent replacement and maintenance are required to keep the hydraulic oil clean. The short service life of the hydraulic oil greatly affects the working efficiency of the piston motor.

[0004] Therefore, in view of the problems of poor heat dissipation and short service life of existing piston motors, a piston motor equipped with a reduction mechanism can be designed to facilitate heat dissipation and cooling of the piston motor, ensure stable operation of the piston motor, and at the same time filter the hydraulic oil to keep the hydraulic oil clean and extend its service life. Utility Model Content

[0005] To overcome the problems of poor heat dissipation in existing piston motors and short service life of hydraulic oil.

[0006] The technical solution of this utility model is as follows: a piston motor equipped with a reduction mechanism includes a motor body, a reducer fixedly connected to the rear end of the motor body, a rotating shaft fixedly connected to the output end of the motor body extending to the outside of the reducer, a filter provided at the front end of the motor body, a cooling pipe provided on the outside of the filter, and a cooling fan provided at the front end of the cooling pipe.

[0007] Preferably, the hydraulic oil circulates through the cooling pipes for effective cooling. The cooling pipes provide uniform cooling and have a large contact area, improving cooling efficiency. At the same time, the cooling pipes reduce the flow rate of the hydraulic oil and the speed of the motor body. The heat generated by the motor body is quickly transferred to the heat sink. The cooling fan drives the airflow to the cooling pipes and heat sink, further dissipating heat and reducing temperature, improving cooling efficiency, and extending the service life of the piston motor.

[0008] Preferably, the surface of the motor body is provided with heat sinks, which are distributed in a ring array.

[0009] Preferably, an oil outlet is fixedly installed on the upper side of the front end of the motor body, and an oil suction port is fixedly installed on the lower side of the front end of the motor body. Two filters are symmetrically arranged, and the front ends of the oil outlet and the oil suction port are fixedly connected to the rear end of the filter.

[0010] Preferably, the filter has a filter box inside, one end of which is rotatably connected to the filter via a damping shaft. Both the front and rear sides of the filter box are covered with sealing rubber strips, and a filter element is installed inside the filter box.

[0011] Preferably, the cooling pipe has a spiral structure, with the inlet end of the cooling pipe connected to the oil outlet through a filter, and the outlet end of the cooling pipe connected to the oil suction port through the same filter.

[0012] Preferably, the cooling fan is provided with a heat dissipation shroud, with a heat dissipation vent at the front end and an air outlet at the rear end, both of which are compatible with the cooling fan.

[0013] Preferably, the motor body and the heat sink are fixedly connected by a connecting rod, and the front end of the cooling pipe is fixedly connected to the rear end of the heat sink.

[0014] The beneficial effects of this utility model are:

[0015] 1. This piston motor equipped with a reduction mechanism uses cooling pipes and a cooling fan. The hydraulic oil circulates through the cooling pipes for effective cooling. The cooling pipes provide uniform cooling and have a large contact area, improving cooling efficiency. At the same time, the cooling pipes reduce the flow rate of the hydraulic oil and reduce the speed of the motor body. The heat generated by the motor body is quickly transferred to the heat sink. The cooling fan drives the airflow to blow air onto the cooling pipes and heat sink, further dissipating heat and reducing temperature, improving cooling efficiency and extending the service life of the piston motor.

[0016] 2. This piston motor equipped with a reduction mechanism uses a filter box and filter. The filter element inside the filter effectively filters contaminants mixed in the hydraulic oil, preventing contaminants from causing abrasive wear on the piston motor parts and extending the service life of the hydraulic oil. After a period of time, the filter box can be turned out of the filter and the filter element replaced. The operation is simple and convenient for maintenance. The sealing rubber strip ensures the integrity and sealing of the filter box, preventing hydraulic oil leakage. Attached Figure Description

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] Please see Figures 1-5 This utility model provides an embodiment: a piston motor equipped with a reduction mechanism, including a motor body 1, a reducer 2 fixedly connected to the rear end of the motor body 1, a rotating shaft 3 fixedly connected to the output end of the motor body 1 extending to the outside of the reducer 2, a filter 4 provided at the front end of the motor body 1, a cooling pipe 5 provided on the outside of the filter 4, and a cooling fan 6 provided at the front end of the cooling pipe 5. In use, the hydraulic oil is filtered through the filter 4 to keep the hydraulic oil clean and prevent impurities from damaging the piston motor. The cooling pipe 5 and the cooling fan 6 dissipate heat and cool down the motor to prevent overheating from causing a decrease in the performance of the piston motor or damage.

[0025] Please see Figure 1 , Figure 3 , Figure 4In this embodiment, an oil outlet 11 is fixedly installed on the upper side of the front end of the motor body 1, and an oil suction port 12 is fixedly installed on the lower side of the front end of the motor body 1. Two filters 4 are symmetrically arranged. The front ends of the oil outlet 11 and the oil suction port 12 are fixedly connected to the rear end of the filter 4. A filter box 41 is provided inside the filter 4. One end of the filter box 41 is rotatably connected to the filter 4 through a damping shaft. The front and rear sides of the filter box 41 are covered with sealing rubber strips. A filter element 42 is provided inside the filter box 41. During use, the filter element 42 inside the filter 4 effectively filters the contaminants mixed in the hydraulic oil, avoiding abrasive wear of the piston motor parts by contaminants and extending the service life of the hydraulic oil. After a period of time, the filter box 41 is turned out of the filter 4 and the filter element 42 is replaced. The operation is simple and convenient for maintenance. The sealing rubber strip ensures the integrity and sealing of the filter box 41 and prevents hydraulic oil leakage.

[0026] Please see Figure 1 , Figure 3 , Figure 4 In this embodiment, the cooling pipe 5 has a spiral structure. The input end of the cooling pipe 5 is connected to the oil outlet 11 through the filter 4, and the output end of the cooling pipe 5 is connected to the oil suction port 12 through the same filter 4. During use, the hydraulic oil circulates through the cooling pipe 5 to effectively cool down. The cooling pipe 5 cools down evenly and has a large contact area, which improves the cooling efficiency. At the same time, the cooling pipe 5 reduces the flow rate of the hydraulic oil and reduces the speed of the motor body 1.

[0027] Please see Figure 1 , Figure 2 , Figure 5 In this embodiment, the surface of the motor body 1 is provided with heat sinks 7, which are arranged in a ring array. The cooling fan 6 is provided with a heat sink cover 61. The front end of the heat sink cover 61 has a heat dissipation port, and the rear end of the heat sink cover 61 has an air outlet. The heat dissipation port and the air outlet are adapted to the cooling fan 6. The motor body 1 and the heat sink cover 61 are fixedly connected by a connecting rod 62. The front end of the cooling pipe 5 is fixedly connected to the rear end of the heat sink cover 61. When in use, the heat generated by the motor body 1 will be quickly conducted to the heat sinks 7, increasing the surface area of ​​the heat sinks 7 and accelerating heat dissipation. With the use of the cooling fan 6, the cooling fan 6 drives the airflow to blow towards the cooling pipe 5 and the heat sinks 7, further dissipating heat and reducing temperature, improving cooling efficiency, and extending the service life of the plunger motor.

[0028] During operation, the filter element 42 inside the filter 4 effectively filters contaminants mixed in the hydraulic oil, preventing contaminants from causing abrasive wear on the plunger motor components and extending the service life of the hydraulic oil. The hydraulic oil circulates through the cooling pipe 5, which provides uniform cooling and has a large contact area, improving cooling efficiency. At the same time, the cooling pipe 5 reduces the flow rate of the hydraulic oil, thus reducing the speed of the motor body 1. The heat generated by the motor body 1 is quickly conducted to the heat sink 7, increasing the surface area of ​​the heat sink 7 and accelerating heat dissipation. In conjunction with the use of the cooling fan 6, the cooling fan 6 drives airflow towards the cooling pipe 5 and the heat sink 7, further dissipating heat and improving cooling efficiency, extending the service life of the plunger motor. After a period of time, the filter box 41 is removed from the filter 4, and the filter element 42 is replaced. The operation is simple and maintenance is convenient.

[0029] Through the above steps, the use of filter box 41 and filter 4 filters the hydraulic oil, extending the service life of the hydraulic oil. The use of cooling pipe 5 and cooling fan 6 enables the plunger motor to effectively dissipate heat and cool down, improving the cooling efficiency, thereby solving the problems of poor heat dissipation effect of existing plunger motors and short service life of hydraulic oil.
