Description

Technical Field

[0001] The utility model relates to the technical field of automatic clutches, in particular to an oil supply interface of a synchronous automatic clutch. Background Art

[0002] In the combined heat and power generation unit, a synchronous automatic clutch is usually installed between the high-pressure rotor and the low-pressure rotor. The synchronous automatic clutch can automatically engage and disengage according to the input and output speeds, so that the unit can flexibly switch between back pressure operation and extraction and condensation operation. When the back pressure mode is required, the low-pressure rotor slows down, the clutch automatically disengages, the low-pressure rotor is decoupled, and the high-pressure rotor runs alone, maximizing the heating capacity of the unit.

[0003] When the unit needs to operate in pure condensing or extraction condensing mode, the low-pressure rotor speed increases to the rated speed, the clutch automatically engages, and the low-pressure rotor is put into operation to maximize the power generation capacity of the unit. The synchronous automatic clutch transmits the torque of the low-pressure rotor through the internal sleeve gear. When the sleeve gear transmits the torque, sufficient lubricating oil is required. At the same time, when the sliding part of the synchronous automatic clutch is engaged or disengaged, a large stroke axial sliding will occur. In order to ensure the smoothness of sliding, the mating surface between the sliding part and the supporting shaft also requires sufficient lubricating oil.

[0004] At present, the lubricating oil required for the synchronous automatic clutch is from the oil storage chamber of the rotors at both ends of the clutch, through the rotor flange oil inlet hole, and then into the clutch support shaft oil inlet hole, and then transported to the lubrication point inside the clutch. In order to ensure that the lubricating oil can enter the clutch support shaft oil inlet hole from the rotor flange oil inlet hole, it is necessary to angularly align the rotor flange oil inlet hole with the clutch support shaft oil inlet hole. However, before the clutch is installed into the rotor flange, the clutch's hoisting state and the rotor flange state are random, and it is necessary to intentionally adjust the clutch's hoisting state or adjust the rotor flange state by turning the wheel. Even if it is adjusted, it is impossible to ensure that the rotor flange oil inlet hole and the clutch support shaft oil inlet hole are aligned at one time, which greatly increases the installation workload of the synchronous automatic clutch. This structure also has the possibility that after the oil inlet hole is installed in a misaligned position, it is not discovered in time, and the clutch cannot be supplied with lubricating oil, which brings hidden dangers to the safe operation of the synchronous automatic clutch. Utility Model Content

[0005] In view of the above technical problems, the utility model provides an oil supply interface for a synchronous automatic clutch which is simple to assemble and does not require a ring groove oil supply interface corresponding to an angular position.

[0006] The utility model provides an oil supply interface for a synchronous automatic clutch, which is characterized by comprising a clutch sliding member, a clutch support shaft and a rotor flange, the clutch sliding member is connected to the clutch support shaft, the clutch support shaft is connected to the rotor flange, a support shaft oil hole is arranged on the clutch support shaft, a support shaft ring groove is arranged on the end face of the clutch support shaft, and a rotor flange oil hole is arranged on the rotor flange.

[0007] The radial width of the supporting shaft ring groove is greater than the diameter of the supporting shaft oil hole.

[0008] The center of the supporting shaft ring groove is consistent with the radial position of the supporting shaft oil hole.

[0009] The support shaft ring groove is a full circle structure, and the support shaft oil holes are evenly distributed around.

[0010] The support shaft ring groove is connected to the rotor flange oil hole in radial position.

[0011] The beneficial effects of the utility model are as follows: in order to solve the existing problems of difficult alignment of the oil holes of the synchronous automatic clutch and inconvenient on-site installation, the utility model proposes a synchronous automatic clutch annular groove oil supply interface, and an annular groove structure is processed at the mating end faces of the clutch support shaft and the rotor flange. The annular groove connects the ends of several oil inlet holes distributed circumferentially on the clutch support shaft. As long as the oil inlet hole of the rotor flange is connected with the annular groove on the clutch support shaft, it can ensure that the lubricating oil can enter the oil inlet hole of the clutch support shaft and then be supplied to the area inside the clutch that needs lubrication. The oil supply annular groove structure is easy to process and can be modified on old equipment, eliminating the process of oil inlet hole alignment when the synchronous automatic clutch is installed on-site, making the installation of the clutch more convenient and efficient, and completely eliminating the problems of misalignment of the oil inlet hole and inability to supply oil to the clutch.

[0016] Example

[0017] The technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the present invention.

[0018] The utility model provides an oil supply interface for a synchronous automatic clutch, which is characterized by comprising a clutch sliding member 1, a clutch support shaft 2 and a rotor flange 3, the clutch sliding member 1 is connected to the clutch support shaft 2, the clutch support shaft 2 is connected to the rotor flange 3, a support shaft oil hole 5 is arranged on the clutch support shaft 2, a support shaft ring groove 7 is arranged on the end surface of the clutch support shaft 2, and a rotor flange oil hole 6 is arranged on the rotor flange 3.

[0019] The radial width of the support shaft ring groove 7 is greater than the diameter of the support shaft oil hole 5 .

[0020] The center of the supporting shaft ring groove 7 is consistent with the radial position of the supporting shaft oil hole 5 .

[0021] The supporting shaft ring groove 7 is a full circle structure, and the supporting shaft oil holes 5 are evenly distributed around.

[0022] The supporting shaft ring groove 7 is connected to the rotor flange oil hole 6 in radial position.

[0023] Example

[0024] exist Figure 1 The conventional synchronous automatic clutch oil supply interface structure is shown in the figure. The lubricating oil required by the synchronous automatic clutch is from the oil storage chamber of the rotor flange 3 at both ends of the clutch, through the rotor flange oil hole 6, and then enters the clutch support shaft oil hole), and then is transported to the clutch internal lubrication point 4. In order to ensure that the lubricating oil can enter the clutch support shaft oil inlet hole 5 from the rotor flange oil hole 6, it is necessary to angularly align the rotor flange oil hole 6 with the clutch support shaft oil hole 5, as shown in the figure. However, before the clutch is installed in the rotor flange, the clutch hoisting state and the rotor flange state are random. In order to ensure that the rotor flange oil hole 6 and the clutch support shaft oil hole 5 are angularly aligned after the clutch is installed, it is necessary to intentionally adjust the clutch hoisting state or adjust the rotor flange 3 state by turning. Even if it is adjusted, it is impossible to ensure that the rotor flange oil hole 6 and the clutch support shaft oil hole 5 are aligned at one time, which will greatly increase the installation workload of the synchronous automatic clutch. This oil supply interface structure also has the problem that if the rotor flange oil hole 6 and the clutch support shaft oil hole 5 are misaligned during installation and are not discovered in time, lubricating oil may not be supplied to the clutch, posing a hidden danger to the safe operation of the synchronous automatic clutch.

[0025] As shown in the figure, the utility model patent processes a support shaft ring groove 7 at the mating end surface of the clutch support shaft 2 and the rotor flange 3. The radial position of the support shaft ring groove 7 is consistent with the radial position of the support shaft oil hole 5. The radial width of the support shaft ring groove 7 is greater than the diameter of the support shaft oil hole 5. The support shaft ring groove 7 can connect the ends of several circumferentially distributed support shaft oil holes 5. As long as the rotor flange oil hole 6 is connected with the clutch support shaft ring groove, it can be ensured that the lubricating oil can enter the clutch support shaft oil hole 5 and then be supplied to the clutch internal lubrication point 4. Since the support shaft ring groove can connect the rotor flange oil hole 6 with the clutch support shaft oil hole 5 at any angular position, as shown in the figure, there is no need to accurately correspond to the angular position of the rotor flange 3 and the clutch support shaft 2, making the installation of the clutch more convenient and efficient, and completely eliminating the equipment safety hazards caused by the misaligned installation of the oil inlet hole and the inability of the clutch to supply oil.

[0026] This synchronous automatic clutch oil supply interface solution can also be used for the transformation of old equipment. It only requires processing a support shaft ring groove 7 of appropriate size at the end surface position of the clutch support shaft 2 corresponding to the oil inlet hole to connect one end of the support shaft oil hole 5. It has no effect on other parts of the clutch and does not require the addition of new parts.
