Reducer is an independent component composed of gear transmission, worm transmission and gear worm transmission enclosed in a rigid housing. It plays the role of matching speed and transmitting torque between prime mover and working machine or actuator. It is widely used in modern machinery. Today, this field is...
1. Data preprocessing Because the point cloud data of the involute cylindrical spur gear measured by the three coordinate machine is regular and the part coordinates are consistent with the software, in the preprocessing stage, only the noise data caused by the influence of the measuring equipment and the...
The cylindrical gear of reducer bears the random load of road surface and the load of driving motor at the input end transmitted by the wheel and half shaft. The remarkable characteristic of these loads is that they are highly random and unpredictable with changes, and their characteristics can...
The primary link of physical reverse engineering is reverse engineering point cloud data acquisition, also known as the digitization of physical surface. The acquisition methods of object surface 3D data in reverse engineering can be divided into two categories: contact and non-contact. Contact type can be divided into point...
1. Establish the precise modification model of cylindrical gear Among the components of electric vehicles, cylindrical gear is the most widely used type of automotive components in the transmission mechanism. Its own composition has a more special design concept and processing technology. In the process of production and processing,...
Generally, during the operation of the automotive electronic control system, the ECU will calculate and judge the physical parameters and working status of the controlled components according to the data flow input by the sensor, and then send the control data flow to the actuator. The actuator works under...
Cylindrical gears have the advantages of strong bearing capacity, stable meshing, convenient processing and adjustment, and are widely used in aviation, automobile and other industries. The dynamic performance of cylindrical gears is very important to the reliability and stable operation of the system, so it has attracted much attention....
Select a single pair of teeth for tooth surface contact stress analysis, import the three-dimensional solid models of double circular arc profile gear and four circular arc profile gear established in Pro /engineer software into ABAQUS software, and set the material elastic modulus E = 2 06 × 105Mpa,...
The single side tooth surface of circular arc tooth profile cylindrical gear is composed of multiple curved surfaces. The establishment of the three-dimensional model of the tooth surface needs to calculate the discrete points on the tooth surface according to the formula, generate the curve from the discrete points,...
1.Calculation of contact stress of cylindrical gear The transmission gear is a cylindrical gear. During the meshing process of the transmission gear, the maximum contact stress on the tooth surface of the cylindrical gear σ H occurs on the pinion. Taking the dynamic output torque of the permanent magnet...
