Description

Technical Field

[0001] The utility model relates to the technical field of torque testing equipment, in particular to a friction type torque limiter testing device. Background Art

[0002] A friction torque limiter is a device used to limit the torque of mechanical equipment. It usually includes friction discs, springs, adjusting nuts and other components, and limits the transmission of torque by adjusting the pressure between the friction discs. When the torque reaches the set limit value, the friction resistance between the friction discs will increase, thereby reducing or stopping the transmission of torque, playing a role in protecting equipment and workers.

[0003] After the friction torque limiter is produced, a series of tests need to be performed. However, the existing test device needs to wait for a long time to cool down after high-temperature testing, which wastes a lot of time and is inconvenient for practical use. Utility Model Content

[0004] The utility model aims to provide a friction torque limiter testing device to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a friction torque limiter testing device, comprising a base plate, a rotating shaft 1, a rotating rod 2 and a control panel, wherein the upper end of the base plate is movably connected with a testing assembly, and the testing assembly comprises a shell 1 and a shell 2.

[0006] Preferably, a motor 1, a torque sensor and a bearing are provided at the upper end of the base plate, a driving wheel is fixedly sleeved on one end of the output shaft of the motor 1, and a driven wheel is fixedly sleeved on the right end of the rotating shaft 1.

[0007] Preferably, the torque sensor is sleeved on the surface of the first rotating shaft, the second rotating rod is fixedly connected to the inner ring of the bearing, and the surfaces of the driving wheel and the driven wheel are sleeved with belts.

[0008] Preferably, the upper end of the base plate is fixedly connected to motor 2, a slide rail, a water collecting tank and a water storage tank, one end of the output shaft of motor 2 is fixedly sleeved with a threaded rod, the surface of the threaded rod is threadedly connected to a moving block, and the upper end of the moving block is fixedly connected to a connecting rod.

[0009] Preferably, the lower ends of shell one and shell two are both provided with through holes, a heating wire and a water pipe are fixedly connected inside shell two, a nozzle is fixedly connected to the lower end of the water pipe, and a water pump is fixedly connected to the upper end of shell two.

[0010] Preferably, the moving block is slidably connected to the slide rail, the threaded rod is rotatably connected to the bottom plate, and the connecting rod is fixedly connected to the shell.

[0011] Preferably, the input end of the water pump is connected to the water tank, and the output end of the water pump is connected to the water pipe.

[0012] Preferably, the control panel is fixedly connected to the housing 2, and the motor 1, motor 2, heating wire and water pump are all electrically connected to the control panel.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. The initial position of shell 1 is a certain distance away from shell 2, which does not affect the installation of the friction torque limiter. After starting motor 2, the moving block drives shell 1 to move toward shell 2 through the connecting rod. When the moving block moves to the front end of the slide rail, shell 1 just contacts shell 2, which facilitates the subsequent internal heating of shell 1 and shell 2.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model.

[0022] like Figures 1 to 3 As shown, a friction torque limiter test device in the embodiment of the first aspect of the utility model includes a base plate 1, a rotating shaft 5, a rotating rod 8 and a control panel 10. The upper end of the base plate 1 is movably connected with a test assembly, and the test assembly includes a shell 1 906 and a shell 2 907. The upper end of the base plate 1 is provided with a motor 2, a torque sensor 6 and a bearing 7. One end of the output shaft of the motor 2 is fixedly sleeved with a driving wheel 3, and the right end of the rotating shaft 5 is fixedly sleeved with a driven wheel 4. The torque sensor 6 is sleeved on the surface of the rotating shaft 5, and the rotating rod 8 and the bearing 7 are connected. The inner ring is fixedly connected, and belts are sleeved on the surfaces of the driving wheel 3 and the driven wheel 4. The upper end of the base plate 1 is fixedly connected to the motor 2 901, the slide rail 903, the water collecting tank 909 and the water storage tank 911. One end of the output shaft of the motor 2 901 is fixedly sleeved with a threaded rod 902, and the surface of the threaded rod 902 is threadedly connected to a moving block 904, and the upper end of the moving block 904 is fixedly connected to a connecting rod 905. The moving block 904 is slidably connected to the slide rail 903, the threaded rod 902 is rotatably connected to the base plate 1, and the connecting rod 905 is fixedly connected to the shell 1 906.

[0023] The technical effect achieved by the above embodiment is: the initial position of shell one 906 is separated from shell two 907 by a certain distance, which does not affect the installation of the friction torque limiter. After starting motor two 901, the moving block 904 drives shell one 906 to move toward shell two 907 through the connecting rod 905. When the moving block 904 moves to the front end of the slide rail 903, shell one 906 just contacts shell two 907, which facilitates the subsequent internal heating of shell one 906 and shell two 907.

[0024] Example 2

[0025] like Figures 1 to 3 As shown, a friction torque limiter testing device includes all the contents of Example 1. In addition, a through hole 908 is opened at the lower end of the shell 1 906 and the shell 2 907, a heating wire 910 and a water pipe 913 are fixedly connected inside the shell 2 907, a nozzle 914 is fixedly connected to the lower end of the water pipe 913, a water pump 912 is fixedly connected to the upper end of the shell 2 907, an input end of the water pump 912 is connected to a water tank 911, an output end of the water pump 912 is connected to the water pipe 913, a control panel 10 is fixedly connected to the shell 2 907, and the motor 1 2, the motor 2 901, the heating wire 910 and the water pump 912 are all electrically connected to the control panel 10.

[0026] The technical effect achieved by the above embodiment is: after detection, the water inside the water tank 911 is transported to the water pipe 913 by starting the water pump 912 and sprayed out through the nozzle 914, which can not only quickly cool down the interior of the shell 1 906 and the shell 2 907, but also quickly cool down the surface of the friction torque limiter, without the need for manual waiting for cooling, thereby improving work efficiency.

[0027] Working principle: install the friction torque limiter between the rotating shaft 1 5 and the rotating rod 2 8, then start the motor 2 901 to drive the threaded rod 902 to rotate, so that the moving block 904 slides on the surface of the slide rail 903, and the moving block 904 drives the shell 1 906 to move in the direction of the shell 2 907 through the connecting rod 905. When the moving block 904 moves to the front end of the slide rail 903, the shell 1 906 just contacts the shell 2 907, and then the heating wire 910 is energized to heat the inside of the shell 1 906 and the shell 2 907 to quickly heat up, and a high temperature test is performed. The motor is started during the test. 1-2 drives the driving wheel 3 to rotate, and the driving wheel 3 drives the driven wheel 4, the rotating shaft 1 5, the friction torque limiter and the rotating rod 2 8 to rotate through the pulley, so that the limit torque data of the friction torque limiter can be measured by the torque sensor 6; after the detection, the water inside the water storage tank 911 is transported to the water pipe 913 by starting the water pump 912 and sprayed out through the nozzle 914, which can not only quickly cool down the interior of the shell 1 906 and the shell 2 907, but also quickly cool down the surface of the friction torque limiter. The cooled water flows into the water collecting tank 909 through the through hole 908 for storage.
