Generally speaking, the coincidence degree of the helical gear system is greater than 2, and the continuous gradual involution of its meshing process makes the process of meshing in and out of the helical gear more stable than that of the spur gear system. However, if the segmented clearance...
Subject to the layout structure of double-input-single-output gears, as shown in Figure 1, the meshing process of the left and right gear pairs is difficult to fully synchronize, and there is a certain phase difference in the stiffness excitation of both sides. Points A, B and C are fixed...
Because of the existence of helical angle, the meshing stiffness of helical gear changes not only with the change of rotation angular displacement, but also with the different positions of the same meshing line at the same time. The helical gear can be divided into a series of slices...
The physical model and simplified torsional vibration model of the rigidly supported double-input-single-output helical gear system are shown in the figure without considering the influence of the rotating shaft and bearing in motion. The system consists of two power input helical gears (p, q), one power output helical gear...
The double-input-single-output helical gear transmission system under asymmetric load has become an important structure in the important power propulsion device of large ships due to its advantages of high power density, compact structure and flexible power parameter ratio. However, due to the particularity of the structure, with the improvement...
Firstly, the grid independence verification process of several sets of “normal contact of two elastic cylinders” is studied, and the general conclusion that the grid size threshold of the contact area is 1/4 times the half-width of the contact zone when the contact pressure and half-width of the contact...
The parameters of a standard helical gear are shown in the table. According to the formula h, the half-width of contact band bg=0.693 7 mm, Hertz contact pressure σ H=997.94 MPa。 Parameters Modulus mn/mm Number of teeth z Helix angle β/ (°) Normal tooth angle α n/(°) Rotation direction...
The meshing solid model of helical gear is established in ANSYS, and the mesh of helical gear is divided and solved according to the general conclusion of mesh control in the contact area obtained from the normal contact simulation analysis of two elastic cylinders. The results of the solution...
Gear transmission is the most widely used transmission form in modern machinery. It has the characteristics of high transmission accuracy, high transmission efficiency, reliable operation and long service life. Gear transmission is composed of spur gear, helical gear, bevel gear and other gear pairs. The traditional gear design is...
When selecting the right gear solution for a particular application, it is important to consider the specific requirements, operating conditions, and performance characteristics. While worm gears offer unique advantages, it’s essential to compare them to other gear types to make an informed decision. Here’s a comparison between worm gears...
