Detailed Description
As shown in fig. 1 to 7, the present invention mainly includes a housing 1, an outer gear sleeve 2 and a temperature detection rod 4, and the coupling and its assembling apparatus of the present invention will be described in detail with reference to the accompanying drawings.
As shown in fig. 1 to 4, the coupling of the present invention includes a first coupling half and a second coupling half, and the first coupling half and the second coupling half have the same structure. First, the outer tooth cover 2 and the shell 1 that the second half-coupling all set up including inside and outside, is fixed with internal tooth 13 at the inner wall of shell, is equipped with external tooth 21 at the outer wall of outer tooth cover, and when external tooth and internal tooth meshing, can drive the rotation of shell through outer tooth cover. An end cover 11 is fixedly mounted on the outer shell of the first coupling half through a first bolt assembly 14, and an end cover 11 is fixedly mounted on the outer shell of the second coupling half through a first bolt assembly 14. The shell of the first half-coupling and the shell of the second half-coupling are fixedly connected together through a second bolt assembly 15, and then the first half-coupling and the second half-coupling are fixedly connected. Lubricating oil is filled in the coupler, so far, the structure of the coupler of the invention is not different from that of the existing coupler.
According to the invention, the temperature detection rod 4 is arranged on the shell of the coupler, and as shown in fig. 5-7, the temperature detection rod 4 is a cylindrical silver rod or copper rod. A heat insulation layer 45 is fixed on the upper part of the temperature detection rod, the heat insulation layer is arranged on the outer side of the temperature detection rod, and after the temperature detection rod is connected with the fastening nut 41, the heat insulation layer is arranged between the temperature detection rod and the fastening nut 41. Also be equipped with insulating layer 45 between the terminal surface of temperature indicating sheet and fastening nut, with the insulating layer interval between fastening nut and the temperature detection stick, can avoid like this that the temperature of temperature detection stick transmits for fastening nut, causes the temperature to detect the distortion. A stud 42 is fixed on the end face of the fastening nut, an external thread is arranged on the stud, and the stud is of a hollow structure. A sealing ring 43 is arranged on the outer side of the stud, and the sealing ring is close to and in contact with the end face of the fastening nut. The temperature detection rod penetrates through the whole fastening nut, the first end of the temperature detection rod penetrates through the fastening nut and the stud and then extends out of one section of the stud, the second end of the temperature detection rod is fixedly provided with a temperature indicating sheet 46 which is made of silver or copper materials, and the thickness of the temperature indicating sheet is 0.2-0.7 cm. The temperature indicating sheet is circular. The temperature detection rod is not contacted with the inner walls of the stud and the fastening nut. Be equipped with the screw hole at the lateral wall of shell, during the use, install the double-screw bolt in the screw hole, realize the fixed connection of temperature detection stick and shaft coupling through fastening nut on the one hand this moment, the first end of on the other hand temperature detection stick is arranged in within the shell, and with the lubricating oil contact in the shell, the temperature indicating sheet is arranged in outside the shell. When the coupler works, the external teeth and the internal teeth are in contact friction, so that the temperature of the external teeth and the internal teeth is increased, and heat transfer is generated between the internal teeth and lubricating oil after the temperature of the internal teeth and the external teeth is increased. Along with the extension of shaft coupling operating time, the temperature of external tooth constantly rises, though lubricating oil can play the effect of cooling to external tooth, the temperature of lubricating oil still can rise, and the temperature of lubricating oil equals or is less than the temperature of external tooth. The first end of the temperature detection rod is always in contact with the lubricating oil, so that the temperature of the lubricating oil is transferred to the temperature detection rod, and the temperature detection rod is a silver rod or a copper rod with good heat conductivity, so that the temperature of the temperature indicating sheet is approximately equivalent to the temperature of the first end of the temperature detection rod.
The temperature indicating paint 44 is coated on the outer side of the temperature indicating sheet, and the temperature of the temperature indicating sheet contacted by the temperature indicating paint can be known through the color change of the temperature indicating paint. The application of the temperature indicating paint is the prior art and is not described in detail herein.
When the temperature detection rod is arranged on the coupler, the temperature indicating coating on the temperature indicating sheet is prevented from being damaged.
The high-speed camera 31 is arranged on the outer side of the coupler and is in signal connection with the server 3, the high-speed camera can acquire images of the temperature indicating sheet, and the high-speed camera is also the prior art and is not described herein any more. The image of the temperature indicating sheet acquired by the high-speed camera can be uploaded to the server and stored in the server. After being processed, the color of the temperature indicating sheet is distinguished, and the temperature of the temperature indicating sheet is further known. According to whether the temperature of the temperature indicating plate exceeds a set value or not, whether the temperature of the outer teeth exceeds the set value or not can be further deduced. Because the temperature detection stick has better heat conductivity, and the temperature detection stick keeps contact with lubricating oil, lubricating oil and external tooth keep contact all the time, and then according to the temperature of temperature detection stick, can infer the temperature of external tooth.
The high-speed camera is arranged on one side of the shell, the coupler is in a rotating state during operation, and the high-speed camera is arranged on one side of the coupler so as to collect images of the temperature detection rod on the coupler. In order to ensure that the shaft coupling is unstable due to gravity center shift during rotation, three temperature detection rods are arranged on the shells of the first half shaft coupling and the second half shaft coupling and are uniformly arranged along the circumferential direction. The temperature detection rod is arranged at a position close to the outer teeth, so that the temperature of the outer teeth can be detected more accurately. The temperature detection rod, the high-speed camera and the server form a temperature detection unit, and the temperature detection unit directly detects the temperature of the lubricating oil and indirectly detects the temperature of the external teeth.
The temperature detection device converts the temperature of the outer teeth on the inner side of the coupler into the temperature of lubricating oil on the inner side of the coupler, converts the temperature of the lubricating oil into the temperature of the temperature detection rod arranged on the outer side of the coupler, and can distinguish the temperature of the temperature detection rod arranged on the outer side of the coupler by collecting image information of the temperature detection rod through the high-speed camera. The temperature of direct detection external tooth is more difficult, but through the conversion of detection object for temperature detection is comparatively convenient. Through the temperature data who detects, can in time know whether the shaft coupling external tooth is in higher temperature state, and then avoid the long-time work of shaft coupling under higher temperature to lead to the destruction of external tooth.
