Description

Technical Field

[0001] The utility model relates to the technical field of rotating shafts, in particular to a low-loss rotating shaft. Background Art

[0002] A rotating shaft generally refers to a rotating component in a machine or device, which is used to transmit power, change direction or support the rotating part. It is widely used in fields such as automobiles, mechanical manufacturing, and construction. In electronic devices and mechanical equipment, the friction and movement generated by the rotating components of bearings or motors will cause heat accumulation.

[0003] The above and existing technologies have the following defects: During the actual use of the rotating shaft, a large amount of heat is generated due to friction during the high-speed rotation of the rotating shaft and accumulates on the shaft body. Since the shaft body itself has slow heat dissipation, the shaft body will be deformed, and then the shaft body will be damaged during high-speed rotation, resulting in safety accidents.

[0004] Therefore, a low-loss rotating shaft is proposed. Content of the Utility Model

[0005] The purpose of the utility model is to solve the problem that a large amount of heat is generated due to friction during the high-speed rotation of the rotating shaft and accumulates on the shaft body. Since the shaft body itself has slow heat dissipation, the shaft body will be deformed, and then the shaft body will be damaged during high-speed rotation, resulting in safety accidents, and a low-loss rotating shaft is proposed.

[0006] To achieve the above purpose, the utility model adopts the following technical scheme: A low-loss rotating shaft includes a shaft body, and a heat dissipation device is arranged on the surface of the shaft body. The heat dissipation device includes two connecting seats, both of the two connecting seats are fixedly connected with the shaft body, a heat conduction plate is fixedly connected to the surface of the connecting seat, two limiting grooves are formed on the surface of the heat conduction plate, limiting rods are slidably connected to the surfaces of the two limiting grooves respectively, a heat collecting plate is fixedly connected to the surface of the limiting rod, a screw ring is fixedly connected to the surface of the heat collecting plate, a plurality of heat dissipation plates are fixedly connected to the arc surface of the screw ring, a screw groove is formed on the surface of the heat conduction plate, and a screw rod is threadedly connected to the surface of the screw groove, and the screw rod is threadedly connected with the screw ring.

[0007] The effects achieved by the above components are as follows: By setting the heat dissipation device, through the cooperation among the connecting seat, the heat conduction plate, the limiting groove, the limiting rod, the heat collecting plate, the screw ring, the heat dissipation plate and the screw groove, the shaft body rotating at high speed can be dissipated heat, avoiding a large amount of heat generated due to friction during the high-speed rotation of the rotating shaft and accumulating on the shaft body. Since the shaft body itself has slow heat dissipation, the shaft body will be deformed, and then the shaft body will be damaged during high-speed rotation, resulting in safety accidents. The heat dissipation efficiency of the shaft body rotating at high speed is improved, and the safety protection effect on the staff is further improved.

[0008] Preferably, a plurality of heat dissipation grooves are formed on the surface of the heat dissipation plate, and the plurality of heat dissipation grooves are evenly distributed on both sides of the heat dissipation plate.

[0009] The effect achieved by the above components is that heat will be discharged through the heat dissipation grooves on the heat dissipation plate. At this time, the heat dissipation grooves can increase the heat dissipation area of the heat dissipation plate and improve the heat dissipation efficiency.

[0010] Preferably, an anti-slip pad is fixedly connected to the surface of the screw ring, and the anti-slip pad is a rubber pad.

[0011] The effect achieved by the above components is that when the screw rod abuts against the anti-slip pad, the anti-slip pad made of rubber at this time can increase the friction between the screw ring and the screw rod.

[0012] Preferably, a fixing ring is fixedly connected to the surface of the heat dissipation plate, and the fixing ring and the screw ring are concentric.

[0013] The effect achieved by the above components is that the heat dissipation plate will drive the fixing ring to rotate. At this time, the fixing ring concentric with the screw ring can increase the stability between the heat dissipation plates.

[0014] Preferably, two sliding holes are formed on the surface of the heat conduction plate, and sliding rods are slidably connected to the surfaces of the two sliding holes. The sliding rods are clamped with the limiting rods. A connecting ring is slidably connected to the arc surface of the sliding rods. The connecting ring is fixedly connected to the heat conduction plate. A spring is sleeved on the arc surface of the sliding rods, and both ends of the spring are fixedly connected to the connecting ring and the sliding rods respectively.

[0015] The effect achieved by the above components is that the pulling ball will drive the sliding rod to move along the surface of the sliding hole. Then the sliding rod will drive one end of the spring to move. At the same time, the spring itself will generate an outward elastic force. At this time, the spring can help the sliding rod to quickly reset. When the limiting rod enters the limiting groove, release the pulling ball. At this time, the spring will drive the sliding rod to be clamped with the limiting rod. At this time, with the cooperation of the sliding hole, the sliding rod, the connecting ring and the spring, the limiting rod can be preliminarily limited.

[0016] Preferably, a pulling ball is fixedly connected to one end of the sliding rod, and the pulling ball is a steel ball.

[0017] The effect achieved by the above components is that pull the pulling ball in the direction away from the heat conduction plate, and then the pulling ball will drive the sliding rod to move along the surface of the sliding hole. At this time, the pulling ball can facilitate the staff to pull the sliding rod.

[0018] Preferably, an auxiliary block is fixedly connected to one end of the limiting rod, and the vertical cross section of the auxiliary block is trapezoidal.

Since the shaft body has a slow self-heat dissipation rate, it will cause the shaft body to deform, and further lead to damage to the shaft body during high-speed rotation, resulting in safety accidents. The heat dissipation efficiency of the high-speed rotating shaft body is improved, and the safety protection effect on the staff is further enhanced. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] In order to more clearly understand the above-mentioned objects, features and advantages of the present utility model, the following further describes the present utility model with reference to the drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0029] In the following description, numerous specific details are set forth to provide a thorough understanding of the present utility model. However, the present utility model may also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited to the limitations of the specific embodiments disclosed in the following specification.

[0030] As Figures 1-5 shown, the present utility model provides a low-loss rotating shaft, including a shaft body 1, and a heat dissipation device 2 is provided on the surface of the shaft body 1.

[0031] Specifically described below are the specific settings and functions of its heat dissipation device 2.

[0032] As Figures 2-5As shown in the figure, the heat dissipation device 2 includes two connecting seats 201. Both of the two connecting seats 201 are fixedly connected to the shaft body 1. A heat conduction plate 202 is fixedly connected to the surface of the connecting seat 201. Two limiting grooves 203 are formed on the surface of the heat conduction plate 202. Limiting rods 204 are slidably connected to the surfaces of the two limiting grooves 203. A heat collecting plate 205 is fixedly connected to the surface of the limiting rod 204. A screw ring 206 is fixedly connected to the surface of the heat collecting plate 205. A number of heat dissipation plates 207 are fixedly connected to the arc surface of the screw ring 206. A screw groove 208 is formed on the surface of the heat conduction plate 202. A lead screw 209 is threadedly connected to the surface of the screw groove 208. The lead screw 209 is threadedly connected to the screw ring 206. A number of heat dissipation grooves 210 are formed on the surface of the heat dissipation plate 207. The number of heat dissipation grooves 210 are evenly distributed on both sides of the heat dissipation plate 207. Heat will be discharged through the heat dissipation grooves 210 on the heat dissipation plate 207. At this time, the heat dissipation grooves 210 can increase the heat dissipation area of the heat dissipation plate 207 and improve the heat dissipation efficiency. An anti-slip pad 211 is fixedly connected to the surface of the screw ring 206. The anti-slip pad 211 is a rubber pad. When the lead screw 209 abuts against the anti-slip pad 211, the anti-slip pad 211 made of rubber at this time can increase the friction between the screw ring 206 and the lead screw 209. A fixing ring 212 is fixedly connected to the surface of the heat dissipation plate 207. The fixing ring 212 and the screw ring 206 are concentric. The heat dissipation plate 207 will drive the fixing ring 212 to rotate. At this time, the fixing ring 212 concentric with the screw ring 206 can increase the stability between the heat dissipation plates 207. Two sliding holes 213 are formed on the surface of the heat conduction plate 202. Sliding rods 214 are slidably connected to the surfaces of the two sliding holes 213. The sliding rods 214 are engaged with the limiting rods 204. A connecting ring 215 is slidably connected to the arc surface of the sliding rod 214. The connecting ring 215 is fixedly connected to the heat conduction plate 202. A spring 216 is sleeved on the arc surface of the sliding rod 214. The two ends of the spring 216 are respectively fixedly connected to the connecting ring 215 and the sliding rod 214. The pulling ball 217 will drive the sliding rod 214 to move along the surface of the sliding hole 213. Then the sliding rod 214 will drive one end of the spring 216 to move. At the same time, the spring 216 itself will generate an outward elastic force. At this time, the spring 216 can help the sliding rod 214 to quickly reset. When the limiting rod 204 enters the limiting groove 203, release the pulling ball 217. At this time, the spring 216 will drive the sliding rod 214 to be engaged with the limiting rod 204. At this time, with the cooperation of the sliding hole 213, the sliding rod 214, the connecting ring 215 and the spring 216, the limiting rod 204 can be initially limited. A pulling ball 217 is fixedly connected to one end of the sliding rod 214. The pulling ball 217 is a steel ball. Pull the pulling ball 217 in the direction away from the heat conduction plate 202. Then the pulling ball 217 will drive the sliding rod 214 to move along the surface of the sliding hole 213. At this time, the pulling ball 217 can facilitate the staff to pull the sliding rod 214. An auxiliary block 218 is fixedly connected to one end of the limiting rod 204. The vertical section of the auxiliary block 218 is trapezoidal. The limiting rod 204 will drive the auxiliary block 218 to move.At this time, the auxiliary block 218 with a trapezoidal vertical section can facilitate the limiting rod 204 to enter the limiting groove 203.

[0033] The overall working principle is as follows. When heat dissipation is required for the shaft body 1, first pull the pulling ball 217 in the direction away from the heat conduction plate 202. Then, the pulling ball 217 will drive the sliding rod 214 to move along the surface of the sliding hole 213. At this time, the pulling ball 217 can facilitate the staff to pull the sliding rod 214. Then, the sliding rod 214 will drive one end of the spring 216 to move, and at the same time, the spring 216 itself will generate an outward elastic force. At this time, the spring 216 can help the sliding rod 214 to quickly reset. Then, insert the two limit rods 204 on the heat collecting plate 205 into the limit slot 203. At the same time, the limit rod 204 will drive the auxiliary block 218 to move. At this time, the auxiliary block 218 with a trapezoidal vertical cross-section can facilitate the limit rod 204 to enter the limit slot 203. When the limit rod 204 enters the limit slot 203, release the pulling ball 217. At this time, the spring 216 will drive the sliding rod 214 to be engaged with the limit rod 204. At this time, with the cooperation of the sliding hole 213, the sliding rod 214, the connecting ring 215 and the spring 216, the limit rod 204 can be preliminarily limited. Then, rotate the screw rod 209. Then, the screw rod 209 will enter the screw ring 206 by virtue of its own thread. At the same time, continue to rotate the screw rod 209, and the screw rod 209 will enter the screw groove 208. Then, when the screw rod 209 abuts against the anti-slip pad 211, the anti-slip pad 211 made of rubber at this time can increase the friction between the screw ring 206 and the screw rod 209, preventing the screw rod 209 from slipping. Then, when the shaft body 1 rotates, it will drive the connecting seat 201 to rotate. Then, the connecting seat 201 will drive the heat conduction plate 202 to rotate. At the same time, the heat conduction plate 202 will drive the heat dissipation plate 207 to rotate. Then, the heat dissipation plate 207 will drive the screw ring 206 to rotate. Then, the heat dissipation plate 207 will drive the fixed ring 212 to rotate. At this time, the fixed ring 212 concentric with the screw ring 206 can increase the stability between the heat dissipation plates 207. Then, when the shaft body 1 rotates, it will generate a certain amount of heat. At this time, the heat will enter the heat conduction plate 202 through the connecting seat 201. Then, the heat conduction plate 202 will transfer the heat to the heat collecting plate 205. At the same time, the heat collecting plate 205 will transfer the heat to the heat dissipation plate 207. Then, the heat will be discharged through the heat dissipation slots 210 on the heat dissipation plate 207. At this time, the heat dissipation slots 210 can increase the heat dissipation area of the heat dissipation plate 207 and improve the heat dissipation efficiency. By setting the heat dissipation device 2, using the cooperation between the connecting seat 201, the heat conduction plate 202, the limit slot 203, the limit rod 204, the heat collecting plate 205, the screw ring 206, the heat dissipation plate 207 and the screw groove 208, the high-speed rotating shaft body 1 can be dissipated heat, avoiding a large amount of heat generated by friction during the high-speed rotation of the rotating shaft and accumulating on the shaft body 1. Since the shaft body 1 itself dissipates heat slowly, it will cause the shaft body 1 to deform, and then cause the shaft body 1 to be damaged during high-speed rotation, resulting in safety accidents. It improves the heat dissipation efficiency of the high-speed rotating shaft body 1 and further improves the safety protection effect for the staff.
