Description

Technical Field

[0001] The utility model relates to the technical field of dual-shaft clutches, in particular to a water-cooled dual-shaft clutch. Background Art

[0002] The dual-axis clutch is a dual-axis magnetic powder clutch, which is based on the electromagnetic principle and uses magnetic powder to transmit torque. It has a basically linear relationship between the excitation current and the transmitted torque. It can transmit a certain torque regardless of the slip, and has the advantages of fast response speed, simple structure, no pollution, no noise, no impact vibration, and energy saving. The traditional dual-axis clutch includes a housing and a brake mechanism arranged inside the housing, and the brake mechanism includes an inner rotor, wherein the inner rotor is composed of a rotating part and a shaft head connected, and the end of the shaft head passes through the housing to cooperate with external tooling. When the brake mechanism is running, the temperature inside it gradually rises, and the temperature of the shaft head also gradually rises. At this time, the inner rotor accumulates heat seriously. Under long-term high-temperature conditions, the service life of the inner rotor decreases, and the high-temperature conditions affect the operating efficiency and operating accuracy of the inner rotor.

[0005] The advantages of adopting the above technical scheme are as follows: when the water-cooled dual-axis clutch is operating, the external water cooling device is started and the water-cooling liquid is transported to the rotating water-cooling joint through the liquid outlet pipe, and the water-cooling liquid is poured into the water cooling circuit through the liquid outlet end. When the inner rotor is operating, it drives the water-cooling liquid to flow in the water cooling circuit, and part of the water-cooling liquid flows to the liquid return end through the liquid outlet end, and then flows back to the external water cooling device through the liquid return end, thereby realizing water cooling circulation in the water cooling circuit, thereby reducing the temperature of the inner rotor, avoiding the inner rotor temperature being too high and heat accumulation seriously affecting the operating efficiency and operating accuracy of the inner rotor when the brake mechanism is running at high speed, and improving the service life of the inner rotor in disguised form; the rotating water-cooling joint in the above technology is the prior art, and when the shaft head rotates, it rotates in conjunction with the shaft head to avoid the phenomenon of jamming between the rotating water-cooling joint and the shaft head. Because it is the prior art, its structure and function and the connection method with the water cooling device will not be described in detail; the reflux and pouring of the water-cooling liquid in the water cooling circuit and the circulation method are all the prior art, so the specific reflux, pouring and circulation methods will not be described in detail.

[0006] The utility model is further provided that: the water cooling circuit comprises a water cooling hole opened in the shaft head along the length direction of the shaft head, and the water cooling hole is connected to the liquid outlet end of the rotary water cooling joint.

[0007] The benefits of adopting the above technical solution are: the water cooling circuit in the above technology includes a water cooling hole opened along the length direction of the shaft head, and the water cooling liquid flowing out from the liquid outlet of the rotating water cooling joint can be poured into the water cooling hole, thereby reducing the temperature of the shaft head when the inner rotor runs at high speed, avoiding the shaft head from heating up too quickly, accumulating too much heat and being too high in temperature, thereby avoiding affecting the operating efficiency and operating accuracy of the inner rotor, and indirectly improving the service life of the inner rotor.

[0008] The utility model is further provided that: the water cooling circuit comprises a water cooling groove which is hollowly opened in the rotor part, the water cooling groove is opened in a ring direction along the axis direction of the shaft head, and the water cooling groove is connected with the water cooling hole.

[0009] The benefits of adopting the above technical solution are: the water cooling circuit in the above technology includes a water cooling tank hollowly opened in the rotor part, and the water cooling liquid flowing out through the liquid outlet of the rotating water cooling joint can be poured into the water cooling hole, and then poured into the water cooling tank through the water cooling hole, thereby reducing the temperature of the rotor part when the inner rotor runs at high speed, avoiding the rotor part from heating up too quickly, accumulating too much heat and having too high a temperature, thereby avoiding affecting the operating efficiency and operating accuracy of the inner rotor, and indirectly improving the service life of the inner rotor.

[0010] The utility model is further configured that: the liquid outlet end is rotatably connected to the shaft head, and a bearing group is connected between the liquid outlet end and the shaft head.

[0011] The advantages of adopting the above technical solution are as follows: the bearing group in the above technology is arranged to improve the transmission accuracy between the liquid outlet end and the shaft head, thereby avoiding the phenomenon of jamming between the liquid outlet end and the shaft head.

[0012] The utility model is further configured that: an external seepage hole is arranged on the rotary water-cooling joint, and the external seepage hole is connected to one side of the bearing group and is arranged close to the shaft head.

[0013] The benefits of adopting the above technical solution are: in the above technology, the external seepage hole is connected to one side of the bearing group and is arranged near the shaft head. When the water-cooling liquid refluxes, a small amount of liquid will seep out to the vicinity of the bearing group. The setting of the external seepage hole prevents the bearing group from being corroded or accumulated by a large amount of water-cooling liquid, affecting the transmission accuracy and service life of the bearing group.
