Description

TECHNICAL FIELD

[0001] The utility model relates to hydraulic coupling technical field, concretely to a novel hydraulic coupling. BACKGROUND

[0002] Hydraulic coupling is a device that uses hydraulic oil as a medium to transmit power. It achieves torque transmission through the circulating flow of hydraulic oil between the pump wheel and the turbine. Hydraulic coupling is widely used in various industrial equipment, with the characteristics of high efficiency, reliability and durability. The working principle of hydraulic coupling is based on hydraulic transmission. When the input shaft rotates, it drives the pump wheel to rotate, and the pump wheel throws out hydraulic oil. These high-speed liquids enter the turbine, pushing the turbine to rotate, thereby transmitting energy to the output shaft. In this process, hydraulic oil forms a circulating flow between the pump wheel and the turbine, achieving continuous power transmission. The structural design of hydraulic coupling can eliminate impact and vibration, protect the motor, improve starting ability, and reduce starting time and average current. Its structure is simple, reliable in operation, no mechanical wear, long service life. Hydraulic coupling has large transmission power and torque, and can realize no-load starting. Because the hydraulic system has small friction loss and high transmission efficiency, it is widely used in many mechanical equipment. In addition, hydraulic coupling also has automatic adjustment and buffering function, which can effectively reduce the impact and vibration in the transmission process.

[0003] The hydraulic coupling hub provided by the present application belongs to the field of couplings, and comprises an inner sleeve, an outer sleeve, an inner layer outer sleeve and an outer layer outer sleeve. The inner sleeve is used for fixedly cooperating with a transmission shaft. The outer sleeve comprises an inner layer outer sleeve and an outer layer outer sleeve. The inner layer outer sleeve is installed in cooperation with the inner sleeve and has an oil storage cavity between the inner layer outer sleeve and the inner sleeve. The outer layer outer sleeve is installed outside the inner layer outer sleeve, and the cooperation surface of the outer layer outer sleeve and the inner layer outer sleeve has a predetermined taper. The outer layer outer sleeve is provided with a first through hole, and the inner layer outer sleeve is provided with a second through hole. The first through hole and the second through hole are communicated with the oil storage cavity. The hydraulic coupling hub of the present application can adjust the maximum hole diameter of the rotating shaft by adjusting or replacing the inner layer outer sleeve and the inner sleeve under the condition that the outer dimension (the diameter of the upper surface of the outer layer outer sleeve) is fixed, thereby reducing the cost of the hydraulic coupling. However, the above-mentioned hydraulic coupling structure is relatively complex, and after pressurization, the fixed effect may be poor due to the wear of the coupling during use. Moreover, the liquid inlet cannot be quickly and conveniently opened and closed for oiling during use. Therefore, a novel hydraulic coupling is proposed. UTILITY MODEL CONTENT

DETAILED DESCRIPTION

[0022] The technical scheme in the embodiments of the utility model will be described clearly and completely below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0023] Please refer to Figures 1-4 The utility model provides a technical scheme: a novel hydraulic coupling, comprising driving shaft 1 and driven shaft 2:

[0024] Driving shaft 1 and driven shaft 2 outside are all set with fixed sleeve 3, and two groups of fixed sleeve 3 are all set with hydraulic chamber 6 inside, two groups of hydraulic chamber 6 are all set with liquid inlet 7 inside, and two groups of liquid inlet 7 are all set with valve assembly inside, two groups of hydraulic chamber 6 are all set with oil storage port 13 on the upper end, and oil storage port 13 is all set with pressure regulating assembly on the upper end.

[0025] The two groups of fixing sleeves 3 are provided with positioning sheets 4 at one end close to each other, and a plurality of positioning holes 5 are oppositely formed on the surfaces of the two groups of positioning sheets 4. The combination of the positioning holes 5 and the positioning sheets 4 can effectively prevent the driving shaft 1 and the driven shaft 2 from axial displacement during operation, ensure the stability of transmission, and increase the contact area between the fixing sleeves 3 by the design of the plurality of positioning holes 5, thereby improving the structural rigidity of the whole coupling, reducing the structural deformation caused by vibration or impact, and realizing quick alignment and installation through the cooperation of the positioning holes 5 and the positioning sheets 4, thereby simplifying the installation steps and improving the work efficiency. When the parts need to be repaired or replaced, the design of the positioning holes 5 makes the disassembly process more convenient and fast, thereby reducing the maintenance cost.

[0026] The valve assembly comprises a mounting sheet 8, a movable rod 9 movably inserted in the middle position of the mounting sheet 8, and a blocking plate 10 provided at the upper end of the movable rod 9. Two groups of holes are formed on the surface of the mounting sheet 8, and the size of the blocking plate 10 is greater than the size of the holes. Through the design of the movable rod 9 and the blocking plate 10, the operator can easily control the opening and closing of the liquid inlet 7 without the need for complex tools or steps. The size of the blocking plate 10 is greater than the size of the holes, which can ensure that the liquid inlet 7 is completely closed in the closed state, thereby effectively preventing the leakage of hydraulic oil.

[0027] A limiting block 11 is provided at the lower end of the movable rod 9, and a return spring 12 is sleeved outside the movable rod 9, and the two ends of the return spring 12 are connected with the mounting sheet 8 and the limiting block 11, respectively. When the valve assembly needs to be closed, the return spring 12 can automatically push the movable rod 9 to move downward, so that the blocking plate 10 tightly fits the holes formed in the mounting sheet 8, realizing quick closing. This design simplifies the operation process and improves the work efficiency. Since the return spring 12 exists, the operator does not need to continuously exert pressure to maintain the closed state of the valve, reducing the need for manual intervention and labor intensity. The limiting block 11 can limit the excessive movement of the movable rod 9, ensuring that the valve assembly will not be accidentally opened in the non-operation state, which helps to prevent hydraulic oil leakage or other safety accidents caused by misoperation or external interference.

[0028] The pressure regulating assembly comprises a rotating sleeve 14 provided outside the oil storage port 13, and an adjusting plug 15 provided inside the rotating sleeve 14. The adjusting plug 15 is inserted into the inside of the oil storage port 13, and is made of polytetrafluoroethylene. Polytetrafluoroethylene has excellent chemical corrosion resistance and can resist the erosion of various chemicals, ensuring the long-term use of the adjusting plug 15 under various working conditions. The friction coefficient of polytetrafluoroethylene is extremely low, which helps to reduce the wear between the adjusting plug 15 and the inside of the oil storage port 13, and improve the service life of the pressure regulating assembly.

[0029] The inner wall of the rotating sleeve 14 is provided with a threaded structure, and the outer side of the oil storage port 13 is provided with a threaded structure matched with the threaded structure, the threaded structure can provide a more secure connection, prevent loosening between the rotating sleeve 14 and the oil storage port 13 due to vibration or impact during use, by rotating the rotating sleeve 14, the position of the rotating sleeve 14 can be adjusted, so as to drive the adjusting plug 15 to move, and then the hydraulic pressure in the fixing sleeve 3 is increased, and the fixing effect is improved.

[0030] Working principle: by installing two groups of fixing sleeves 3 on the outer side of the driving shaft 1 and the driven shaft 2 respectively, then adding hydraulic oil into the hydraulic chamber 6 through the adjusting valve assembly, after the oiling is completed, the reset spring 12 can automatically push the movable rod 9 to move downward, so that the blocking plate 10 is tightly attached to the hole of the fixed plate, then the adjusting of the pressure regulating assembly arranged on the oil storage port 13 is ensured, then the driving shaft 1 and the driven shaft 2 are fixed through the positioning piece 4 and the positioning groove.
