Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of couplings, in particular to a novel through-type drum-shaped gear coupling. Background Art
[0002] The drum gear coupling is a rigid-flexible coupling consisting of an inner ring gear with the same number of teeth and a flanged half coupling with external teeth. The external teeth are available in two types: spur and drum gear. The drum gear coupling allows for greater angular displacement, improving tooth contact, increasing torque transmission, and extending service life. Furthermore, the coupling's modular design allows for easy assembly and disassembly based on specific needs. This not only facilitates installation and maintenance but also allows for the coupling's performance to be adjusted according to actual operating conditions. For example, if the equipment's torque requirements change, different modules can be swapped out to meet the requirements.
[0003] The shaft is prone to locking when rotating, which greatly reduces work efficiency. When the coupling is operating, it produces noise and strong vibration due to high-speed operation. For this reason, we propose a new through-type drum gear coupling. Utility Model Content

[0010] As a preferred technical solution of the present invention, the inner wall of the outer ring is provided with a plurality of steel balls, and the plurality of steel balls are distributed on the inner wall of the outer ring in a circular array.
[0011] Compared with the prior art, the present invention has the following beneficial effects:
[0012] 1. This new through-type drum gear coupling, by clamping the anti-lock bearing in front of the rotating shaft, is not only easy to disassemble, but also greatly increases the efficiency of the coupling. The addition of shock-absorbing and noise-reducing components to the outer ring of the bearing can effectively reduce the vibration and noise caused by the equipment during operation. The through-type coupling, which combines rubber shock-absorbing pads and sound insulation materials, can effectively absorb vibration and noise during equipment operation, making the equipment run quieter and more stable.
[0013] 2. This new through-type drum gear coupling also clamps the bearing on the outside of the rotating shaft to effectively prevent the machine from locking due to the different speeds on both sides during long-term operation. The coupling can automatically adjust its own position and angle through multiple steel balls to maintain good transmission performance. This adaptive structure can reduce the vibration and noise of the equipment, reduce the shaking caused by the offset of internal parts when the equipment runs too fast, and improve the stability and reliability of the equipment. In addition, the inner ring is equipped with an oil storage tank and a brush rod to lubricate the equipment while it is running, preventing oxidation and rusting of the equipment after long-term use, and effectively extending its service life.

In addition, a plurality of fixing bolts 2 are provided on the outer wall to make disassembly more convenient and convenient for replacement. By adding shock-absorbing and noise-reducing elements to the coupling, the vibration and noise of the equipment can be effectively reduced, which can not only improve the working environment quality of the equipment, but also reduce the impact of the equipment on the surrounding environment. The through-type coupling combining rubber shock-absorbing pads and sound insulation materials can effectively absorb the vibration and noise during the operation of the equipment, making the equipment run more smoothly and quietly.
[0024] See also Figure 4 The outer wall of the outer ring 71 is provided with an outer ring 79 on the side away from the sealing ring 74, and the outer wall of the outer ring 79 is fixedly connected with multiple limiting protrusions 710. The arrangement of the multiple limiting protrusions 710 makes it easy to rotate the outer shaft to loosen the groove for easy disassembly when the internal structure is damaged or needs to be inspected.
[0025] See also Figure 6An oil inlet 75 is provided on the outer wall of the outer ring 71, and an oil storage tank 76 is provided on the inner wall of the outer ring 71 on the side close to the steel ball 72. A fixed roller 77 is fixedly connected to the outer wall of the oil storage tank 76, and a brush roller 78 is provided on the inner wall of the fixed roller 77. The setting of the fixed roller 77 makes it difficult for the brush roller 78 to shake during the rolling process, thereby preventing the brush roller 78 from shifting and causing a decrease in efficiency.
[0026] See also Figure 2 The sleeve 3 includes an inner cavity 31 located on the inner wall of the flange 1, and a plurality of drum gears 32 are provided on the outer wall of the inner cavity 31.
