Drum gear coupling is a kind of coupling with a higher usage rate. Compared with straight gear coupling, it can allow greater angular displacement, and the angular compensation is greater than that of straight gear coupling. The contact conditions of the teeth are greatly improved, so the service life of the coupling is increased.
There may be some problems in the use of the coupling, such as the imbalance of the rotor.The phenomenon of unbalanced centrifugal inertial force, centrifugal inertial couple force and dynamic deflection (vibration shape) during operation is called the unbalanced phenomenon of the rotor.
When the lubrication effect of the coupling and the bearing bush fails to meet the requirements, a variety of failure characteristics will appear.If the oil pressure is low, the part between the shaft and the bearing bush will cause dry friction due to direct contact and cause damage and damage to the moving surface. At this time, the shaft surface is blue.
The structure of the plum blossom coupling is simple, the number of parts is small, the radial dimension is small, and there is no need for lubrication; the elastic element has a high pressure bearing capacity.Except for the double-flange quincunx elastic coupling, the half-coupling must be moved axially when replacing the vulnerable quincunx elastic parts.This kind of coupling has a certain ability to compensate the relative deviation of the two shafts.
With the continuous improvement of the quality and performance of our country’s sewing equipment, power tools, garden machinery and instrument machinery, the application and demand for high-quality small modulus bevel gear couplings are also increasing year by year, and their manufacturing accuracy and quality are facing even greater challenges. Great challenge.
In order to solve the problem of the fragile damage of the traditional diaphragm assembly, a diaphragm coupling with a patch is first designed based on the TRIZ theory, and then the CosmosWorks software is used to analyze the diaphragm group of the traditional coupling and the diaphragm with a patch diaphragm coupling. The film set was analyzed.
Coupling is a device that connects two shafts or shafts and rotating parts, and rotates together without disengaging during the process of transmitting motion and power (torque). During the transmission process, the direction of rotation and the magnitude of the torque are not changed. It is the common function of all kinds of couplings.
The main elastic drum-shaped gear coupling of the high elastic coupling is a torsionally loaded rubber component. The rubber component can be designed in a single row or multiple rows. Each rubber component has a variety of standard stiffnesses to choose from, which can be used in a wide range of To meet the rigidity requirements determined by the torsional vibration calculation, the drum-shaped gear coupling.
