Timken bearing gear transmission equipment Application Technology Analysis
Timken gear transmission equipment is widely used in various industries, the type and size varied, need to meet the application requirements also vary. And as one of the key components of various gear bearing equipment, its performance directly determines the life of the whole device to some extent. Therefore, the gear transmission equipment in the selected bearing the necessary analysis and calculations are essential. While avoiding the calculated bearing L10 life theory is equivalent to the entire contents of the analysis of bearing applications, especially for gear transmission device, the application environment very different walks of life, even in the analysis of bearings with a different position of the gear device to be the focus should also be different.
Application of bearings under low speed conditions
Most of the reduction gear device is applied, it is often the output shaft rotational speed are the lowest. Different sectors of the output shaft speed is different, generally two dozen turn, some even only a dozen revolutions per minute per minute. If you ignore the loss, the power transmission substantially unchanged, so that the output shaft of the torque are generally large, low speed high torque applications, the most concern is the lubrication of the bearing, which is the film formation problem. The role of oil film bearing operation at the time of separating the two metal contact surfaces, avoid direct contact occurs between the metal and the metal. We generally use the parameters to characterize the effect of lubrication λ (λ is defined as the film thickness and roughness of the two contact surfaces and the ratio). If λ is greater than 1, indicating that the oil film thickness sufficient to separate the two metal surfaces, good lubricating effect, and if λ is less than 1, it indicates that the oil film thickness is not sufficient to separate the two metal surfaces, the lubricating effect is not ideal. Bearing in operation process if the λ value is less than 1, it may appear as shown in Figure 1 of injury.
